A pistol grip handle has a handle axis and an upper end that is positioned below a lower end of the air treatment member. A portion of the air treatment member is positioned between the upper end of the pistol grip handle and the pre-motor filter housing or the pre-motor filter. When the hand vacuum cleaner is horizontal, a vertical projection of the upper end of the pistol grip handle extends through the pre-motor filter housing. The suction motor may be positioned rearward of the pre-motor filter housing. This configuration of the hand vacuum cleaner and the pistol grip handle provides enhanced ergonomics and/or an expanded air treatment member volume.

- Referring to
FIGS. 1-4 , an exemplary embodiment of a surface cleaning apparatus is shown generally as 100. The following is a general discussion ofsurface cleaning apparatus 100, which provides a basis for understanding several of the features that are discussed herein. As discussed subsequently, each of the features may be used individually or in any particular combination or sub-combination in this or in other embodiments disclosed herein. - In the illustrated embodiment,
surface cleaning apparatus 100 is a hand vacuum cleaner. As used herein, a hand vacuum cleaner is a vacuum cleaner that can be operated to clean a surface generally one-handedly. That is, the entire weight of the hand vacuum cleaner may be held by the same hand as the one used to direct a dirty air inlet of the hand vacuum cleaner with respect to a surface to be cleaned. For example, the handle and the dirty air inlet of the hand vacuum cleaner may be rigidly coupled to each other (directly or indirectly) so as to move as one while maintaining a constant orientation relative to each other. This is to be contrasted with canister and upright vacuum cleaners, whose weight is typically supported by a surface (e.g., a floor) during use. When a canister vacuum cleaner is operated or when an upright vacuum cleaner is operated in a ‘lift-away’ configuration, a second hand is typically required to direct the dirty air inlet at the end of a flexible hose. -
Surface cleaning apparatus 100 includes amain body 102 having an air treatment assembly 104 (which may be permanently affixed tomain body 102 or may be removable in part or in whole therefrom for emptying, and optionally is removable as a sealedair treatment assembly 104 other than the air treatment assembly air inlet and the air treatment assembly air outlet), adirty air inlet 106, aclean air outlet 108, and an air flow path extending betweendirty air inlet 106 andclean air outlet 108.Air treatment assembly 104 may comprise one or more air treatment members. -
Surface cleaning apparatus 100 has afront end 110, arear end 112, anupper end 114, and alower end 116. In the illustrated embodiment,dirty air inlet 106 is at an upper portion offront end 110 andclean air outlet 108 is at a rearward portion ofmain body 102. It will be appreciated thatdirty air inlet 106 andclean air outlet 108 may be provided in different locations. As exemplified inFIG. 29A ,hand vacuum cleaner 100 has a hand vacuumcleaner axis 115 that extends between thefront end 110 and therear end 112. Unless expressly stated otherwise, any description herein that relates to the position of one or more hand vacuum cleaner components relative to the position of one or more other hand vacuum cleaner components is made when the hand vacuumcleaner axis 115 is horizontal and in the orientation ofFIG. 29 wherein the upper end of the hand vacuum cleaner is above the lower end of the hand vacuum cleaner. - A
suction motor 118 is positioned in the air flow path to generate vacuum suction through the air flow path.Suction motor 118 is positioned within a body portion 120 (which may be part of the main body 102). Thesuction motor 118 may be provided inbody portion 120 ofmain body 102 and, optionally, asuction motor housing 119 may be provided inbody portion 120.Suction motor 118 may be a fan-motor assembly including an electric motor and impeller blade(s).Suction motor 118 defines a motor axis 122 (about which the impeller rotates). In the illustrated embodiment,suction motor 118 is positioned downstream ofair treatment assembly 104. In this configuration,suction motor 118 may be referred to as a “clean air motor”. Alternatively,suction motor 118 may be positioned at alternate locations, such as upstream ofair treatment assembly 104 in which case it may be referred to as a “dirty air motor”. -
Suction motor 118 may be oriented in any direction. For example, whensurface cleaning apparatus 100 is oriented with theupper end 114 above thelower end 116, e.g., positioned substantially parallel to a horizontal surface,motor axis 122 may be oriented horizontally (as exemplified inFIG. 2 ) or vertically (as exemplified inFIG. 6 ). In alternative embodiments,suction motor 118 may be oriented at any angle between horizontal and vertical. As described below,suction motor 118 may have various positional arrangements, which may improve the ergonomics of the hand vacuum cleaner 100 (e.g., reduced weight, better weight balance, or greater portability). - The air treatment member or members of
air treatment assembly 104 are configured to remove particles of dirt and other debris from the air flow. The air treatment member or members ofair treatment assembly 104 may comprise one or more cyclonic stages, each of which may comprise a single cyclone or a plurality of cyclones in parallel. Each cyclonic stage may have a single dirt collection chamber or a plurality of dirt collection chambers. The dirt collection chamber(s) may be external to the cyclone chamber or may be internal to the cyclone chamber and configured as a dirt collection area or region within the cyclone chamber. Alternatively,air treatment assembly 104 need not include a cyclonic cleaning stage, and can comprise any air treatment chamber known in the vacuum cleaner arts and/or may optionally incorporate a bag, a porous physical filter media (such as foam or felt), or other air treating means. - As exemplified in
FIGS. 1-4 ,air treatment assembly 104 utilizes an air treatment chamber that is acyclone chamber 124 and has an externaldirt collection chamber 126.Cyclone chamber 124 has first and second cyclone ends 128, 130 and acyclone sidewall 132 that extends between first and second cyclone ends 128, 130.Cyclone chamber 124 has acyclone axis 134 that extends between first and second cyclone ends 128, 130. -
Cyclone chamber 124 may be oriented in any direction. As exemplified inFIG. 2 , whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116, e.g., positioned substantially parallel to a horizontal surface,cyclone axis 134 may be oriented vertically. In these configurations, first and second cyclone ends 128, 130 may be referred to as cyclone upper and lower ends 128, 130, respectively. Alternatively, as exemplified inFIG. 29 , whenhand vacuum cleaner 100 is oriented withupper end 114 abovelower end 116, e.g., positioned substantially parallel to a horizontal surface,cyclone axis 134 may be oriented horizontally. In these configurations, first and second cyclone ends 128, 130 may be referred to as cyclone front andrear ends cyclone chamber 124 may be oriented at any angle between horizontal and vertical. - Air circulates about
cyclone axis 134 when incyclone chamber 124. Accordingly,cyclone axis 134 is alternatively referred to herein as a “cyclone axis of rotation”.Cyclone chamber 124 includes acyclone air inlet 136 in fluid communication with aninlet conduit 138, acyclone air outlet 140, and adirt outlet 142 that is in communication with thedirt collection chamber 126. As exemplified inFIG. 2 ,cyclone chamber 124 may have asingle dirt outlet 142. Alternatively,cyclone chamber 124 may include two or more dirt outlets that are in communication with the same dirt collection chamber, or optionally with different dirt collection chambers. -
Cyclone air inlet 136,cyclone air outlet 140 anddirt outlet 142 may be of any design and positioning that is known in the art. Preferably,cyclone air inlet 136 is generally tangentially oriented relative tocyclone sidewall 132, so that air entering thecyclone chamber 124 will tend to swirl and circulate withincyclone chamber 124, thereby disentraining dirt and debris from the airflow, before leavingcyclone chamber 124 throughcyclone air outlet 140. -
Cyclone chamber 124 may optionally be a ‘uniflow’ cyclone chamber (i.e., where the cyclone air inlet and cyclone air outlet are at opposite ends of the cyclone chamber). Alternatively,cyclone chamber 124 may provide bidirectional air flow (i.e., where the cyclone air inlet and cyclone air outlet are at the same end of the cyclone chamber). In the illustrated embodiments,cyclone chamber 124 uses bidirectional air flow. As exemplified inFIG. 2 ,cyclone air inlet 136 andcyclone air outlet 140 may be both provided at cycloneupper end 128. As exemplified inFIG. 29 ,cyclone air inlet 136 andcyclone air outlet 140 may be both provided at cyclonerear end 130. Optionally,cyclone chamber 124 may be an inverted cyclone chamber with thecyclone air inlet 136 andcyclone air outlet 140 provided at the lower end. - As exemplified in
FIG. 2 ,dirt collection chamber 126 may be external to cyclone chamber 124 (i.e.,dirt collection chamber 126 may have a discrete volume from that ofcyclone chamber 124 and in communication withcyclone chamber 124 through dirt outlet 142). In such an embodiment, thedirt outlet 142 may be at any location. For example, it may be at the same end as the air treatment chamber air outlet. Alternately, as exemplified inFIG. 2 , thedirt outlet 142 is vertically spaced apartcyclone air inlet 136 andcyclone air outlet 140. - As previously discussed, dirt collection chamber(s) may be internal to the cyclone chamber (or a non-cyclonic air treatment chamber) and configured as a dirt collection area or region within the cyclone chamber (or a non-cyclonic air treatment chamber). For example,
FIG. 29A shows an example embodiment in whichair treatment assembly 104 has adirt collection region 127 that is internal tocyclone chamber 124. In this embodiment,cyclone chamber 124 anddirt collection region 127 share one contiguous volume. Dirt and debris separated from the air stream within thecyclone chamber 124 can fall todirt collection region 127 without passing through a dirt outlet. -
Cyclone chamber 124 anddirt collection chamber 126 may be of any configuration suitable for separating dirt from an air stream and collecting the separated dirt respectively andcyclone air inlet 136 andcyclone air outlet 140 may be of any design and position known in the art. As exemplified inFIGS. 2 and 29B ,dirt collection chamber 126 may be positioned belowcyclone chamber 124 whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116. Alternatively, or in addition,dirt collection chamber 126 may surround part of all of cyclone chamber 124 (see, e.g.,FIG. 31 ). - In the illustrated embodiment,
cyclone air outlet 140 includes avortex finder 144. As exemplified inFIG. 2 , thevortex finder 144 may consist of or comprise amesh screen 146 to help filter lint, fluff, and other debris, such as hair, that remains in the exiting air flow.Mesh screen 146 may extend inwardly into the cyclone chamber from a solid outlet conduit. - Preferably, at least a portion of
air treatment assembly 104 may be openable for emptying. For example, at least one end (e.g., the bottom end as exemplified inFIG. 3 or the front end as exemplified inFIG. 31 ) may be openable. Optionally both ends oftreatment assembly 104 may also be openable for emptying. The openable end may open the dirt collection chamber and/or the air treatment chamber. - In the illustrated embodiment of
FIG. 3 , thebottom end wall 148 ofcyclone chamber 124 and thebottom end wall 150 ofdirt collection chamber 126 and are both provided by portions of anopenable door 152. Accordingly, in this arrangement,openable door 152 may be referred to as a “bottom door”. In this arrangement, openingbottom door 152 concurrently opensbottom end walls dirt collection chambers Bottom door 152 may be movably connected (e.g., pivotally openable or removably mounted) toair treatment assembly 104 using any suitable mechanism, including a hinge or other suitable device. Optionally,bottom door 152 may be secured in the closed position using any suitable type of locking mechanism. As exemplified inFIG. 1 ,bottom door 152 may be held in the closed position by alatch 154 that may be released by a user. In the illustrated embodiment ofFIG. 31 ,openable door 152 may be referred to as a “front door” and movably connected toair treatment assembly 104 in a similar fashion as the bottom door discussed above. It will be appreciated that the openable end of an air treatment chamber or the air treatment assembly may comprise or consist of an end wall. It will also be appreciated that if an external dirt collection chamber is provided, that theair treatment chamber 124 and thedirt collection chamber 126 may be concurrently openable (see e.g.,FIGS. 3 and 31 ). - As exemplified in
FIG. 2 , a deflector orarrestor plate 156 may be positioned at cyclonelower end 130, at the interface betweencyclone chamber 124 anddirt collection chamber 126. In such an embodiment, thedirt outlet 142 may be provided by one or more gaps between thearrestor plate 156 and the end of thesidewall 132 of thecyclone chamber 124. Alternately, thearrester plate 156 may abut the end of thecyclone sidewall 132 and the sidewall may have a slot which defines thedirt outlet 142. Accordingly, for example,arrester plate 156 may be sized to cover substantially all of cyclonelower end 130, and to abut the lower end ofcyclone sidewall 132 to formbottom end wall 148 ofcyclone chamber 124. Whenarrestor plate 156 abuts the lower end ofcyclone sidewall 132 it may define part of the gaps or slots that formdirt outlet 142. For example,dirt outlet 142 may be bounded on three sides bycyclone sidewall 132 and on a fourth side byarrestor plate 156. Alternatively,cyclone sidewall 132 may be spaced apart fromarrestor plate 156 and the dirt outlet is defined by the gap between thearrester plate 156 and the end of thecyclone sidewall 132. - Optionally,
arrestor plate 156 may be fixed in its position with respect tocyclone sidewall 132 or may be moveable or openable. Providing anopenable arrestor plate 156 may help facilitate emptying ofcyclone chamber 124. Optionally,arrestor plate 156 may be openable concurrently with another portion of the surface cleaning apparatus, including, for example,dirt collection chamber 126. - In the illustrated embodiment,
arrestor plate 156 is mounted to and supported spaced frombottom end wall 150 ofdirt collection chamber 126 by asupport member 158.Support member 158 may be of any suitable configuration and may be formed from any suitable material that is capable of supportingarrestor plate 156 and resisting stresses exerted onarrestor plate 156 by the air flow incyclone chamber 124 or dirt particles exitingcyclone chamber 124. In this configuration,arrestor plate 156 is movable concurrently withbottom end wall 150 ofdirt collection chamber 126, so that openingbottom end wall 150 simultaneously openscyclone chamber 124 anddirt collection chamber 126. Alternatively,arrestor plate 156 may be mounted to cyclone sidewall 132 (or other portion of the surface cleaning apparatus) and need not open in unison withbottom end wall 150 ofdirt collection chamber 126. - Optionally, one or more pre-motor filters may be placed in the air flow path between
air treatment assembly 104 andsuction motor 118. In the illustrated embodiment ofFIG. 2 ,hand vacuum cleaner 100 includes apre-motor filter housing 160 provided in the air flow path downstream ofair treatment assembly 104 and upstream ofsuction motor 118. As exemplified,pre-motor filter housing 160 may be provided as a portion ofmain body 102, aboveair treatment assembly 104. Alternatively,pre-motor filter housing 160 may be provided elsewhere betweenair treatment assembly 104 and suction motor 118 (e.g.,pre-motor filter housing 160 may be rearward ofair treatment assembly 104 as exemplified inFIG. 29 ). - In some embodiments, a portion of the
air treatment member 104 underlies thepre-motor filter housing 160. In these embodiments, thepre-motor filter housing 160 may be provided rearward of an air outlet of theair treatment member 104. As exemplified inFIG. 29A , thepre-motor filter housing 160 is rearward of thecyclone air outlet 140 and aportion 125 ofdirt collection region 127 underlies thepre-motor filter housing 160. This configuration may expand the volume of theair treatment member 104 without increasing overall vacuum cleaner size. - As exemplified in
FIG. 29B , thepre-motor filter housing 160 is rearward of thecyclone air outlet 140 and aportion 125 ofdirt collection chamber 126 underlies thepre-motor filter housing 160. In this embodiment, thedirt collection chamber 126 is external to airtreatment chamber 124. This configuration may expand the capacity of thedirt collection chamber 126 without increasing overall vacuum cleaner size. -
Pre-motor filter housing 160 may be of any suitable construction, including any of those exemplified herein. One or morepre-motor filters 162 may be positioned withinpre-motor filter housing 160. Pre-motor filter(s) 162 may be formed from any suitable physical, porous filter media and having any suitable shape, including the examples disclosed herein with respect to a removable pre-motor filter assembly. For example,pre-motor filter 162 may be one or more of a foam filter, felt filter, HEPA filter, other physical filter media, electrostatic filter, and the like. - In some embodiments, at least a portion of
pre-motor filter 162 may be positioned overlying at least a portion ofair treatment assembly 104. In some embodiments, at least 50% (e.g., 50%, 60%, 70%, 80%, 90% or more) ofpre-motor filter 162 may be positioned overlyingair treatment assembly 104. As an example, the illustrated embodiment ofFIG. 2 shows 100% ofpre-motor filter 162 overlyingair treatment assembly 104. - The diameter or length of the
pre-motor filter 162 in a plane transverse to the cyclone axis ofrotation 134 may be least 50% (e.g., 50%, 60%, 70%, 80%, 90%, 100% or more) of the diameter or length of theair treatment assembly 104 in the same plane. - As exemplified in
FIG. 2 ,pre-motor filter housing 160 may be bounded by abottom wall 164, asidewall 166 and anupper wall 168. In the illustrated embodiment,upper wall 168 is provided by anupper cover 170. Preferably, at least one ofbottom wall 164,sidewall 166 andupper cover 170 are openable to allow access to the interior ofpre-motor filter housing 160. In the illustrated embodiment,upper cover 170 is removable (seeFIG. 4 ) to provide access to the interior ofpre-motor filter housing 160. Alternatively, instead of being removable,upper cover 170 may be pivotally openable or otherwise moveably coupled tomain body 102. - Alternately, if the air treatment assembly is removable, then the
pre-motor filter 162 may be accessible when the air treatment assembly is removed. For example,pre-motor filter housing 160 may be removable frommain body 102 with theair treatment assembly 104. For example,pre-motor filter housing 160 andair treatment assembly 104 may be detachably mounted tomain body 102. Alternately,pre-motor filter housing 160 may remain in place withmain body 102 whenair treatment assembly 104 is removed. For example,air treatment assembly 104 may be detachably mounted by itself tomain body 102 and optionally topre-motor filter housing 160. - Optionally, one or more post-motor filters may be positioned in the air flow path between
suction motor 118 andclean air outlet 108 to help further treat the air passing through thehand vacuum cleaner 100. As exemplified inFIG. 2 ,hand vacuum cleaner 100 may include an optionalpost-motor filter 172 provided in the air flow path downstream ofsuction motor 118 and upstream ofclean air outlet 108. In the illustrated embodiment,post-motor filter 172 is provided inbody portion 120, rearward ofsuction motor 118. As described herein below, various alternative positions ofpost-motor filter 172 are possible.Post-motor filter 172 may be formed from any suitable physical, porous filter media for filtering air in the airflow path downstream ofsuction motor 118 and may be of any suitable shape.Post-motor filter 172 may be any suitable type of filter such as one or more of a foam filter, felt filter, HEPA filter, other physical filter media, electrostatic filter, and the like.Clean air outlet 108 may form part of an optional post-motor filter housing. - As exemplified in
FIGS. 2A and 29C-29D , thesurface cleaning apparatus 100 may include a first movable portion and a second movable portion. The first and second movable portions may be movably connected by anaccess pivot 117, such as a hinge or other suitable device. The movable portions may be held together by a latch or any other suitable coupling means that may be released by a user. Rotating one or both movable portions about theaccess pivot 117 may provide access to one or more components internal to thesurface cleaning apparatus 100, such as one or more ofsuction motor 118,pre-motor filter 162,post-motor filter 172,cyclone chamber 124, anddirt collection chamber 126, such as for cleaning, emptying, replacement, other maintenance purposes, or any other reason. Accordingly, the movable portions may be any two portions of the surface cleaning apparatus. For example, as shown inFIGS. 2A and 29D , the first movable portion is theair treatment assembly 104 and the second movable portion is themain body 102. As another example, as shown inFIG. 29C , the first movable portion is thepre-motor filter housing 160 and the second movable portion is thesuction motor housing 119. It will be appreciated that more than one access pivot and more than two movable portions may be used for access to a greater number of components and/or for additional directions of access thereto. -
Inlet conduit 138 extends fromdirty air inlet 106 tocyclone air inlet 136. In the illustrated embodiment,dirty air inlet 106 ofhand vacuum cleaner 100 is aninlet end 174 ofinlet conduit 138. Optionally,inlet end 174 ofinlet conduit 138 can be used as a nozzle to directly clean a surface.Inlet conduit 138 is, in this example, a generally linear hollow member that extends along aninlet conduit axis 176 that is oriented in a longitudinal forward/rearward direction and is generally horizontal whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116. Alternatively, or in addition to functioning as a nozzle,inlet conduit 138 may be connectable or directly connectable to the downstream end of any suitable accessory tool such as a rigid air flow conduit (e.g., an above floor cleaning wand), a crevice tool, a mini brush, and the like. -
FIGS. 1-4 exemplify aninlet conduit 138 positioned forward ofair treatment assembly 104 and at an upper end of the hand vacuum cleaner. In this configuration,inlet conduit axis 176 intersects body portion 120 (seeFIG. 2 ). Alternatively, in the illustrated embodiment ofFIGS. 29, 29B and 30 ,inlet conduit 138 may be positioned aboveair treatment assembly 104 whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116. In the embodiment ofFIG. 29 ,inlet conduit axis 176 intersectspre-motor filter housing 160. Alternately or in addition, as exemplified in the embodiment ofFIG. 29B ,inlet conduit axis 176 may intersect an energy storage member such as supplementaryenergy storage pack 302. Alternatively, in the illustrated embodiment ofFIGS. 48 and 49 ,inlet conduit 138 may be positioned belowair treatment assembly 104 whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116. In this configuration,inlet conduit axis 176 intersectspre-motor filter housing 160. In some embodiments,inlet conduit axis 176 may intersect bothsuction motor 118 and first energy storage pack 300 (see, e.g.,FIG. 11 ). - In some embodiments, the
inlet conduit 138 can be provided on the openable door 152 (see e.g.,FIGS. 29, 29A, 31 and 33 ). In these embodiments, theinlet conduit 138 moves with the door 152 (see e.g.,FIG. 31 ). As exemplified in the alternate positions shown in dotted outlines inFIG. 29A , the inlet conduit 138 (shown in broken lines) can be positioned proximate the upper or lower end of theopenable door 152. Alternatively, theinlet conduit 138 can be provided at any suitable location between the upper and lower ends of thedoor 152. This positioning of theinlet conduit 138 may be used with any one or more other configurations of an element of a hand vacuum cleaner as discussed herein. - In other embodiments, the
inlet conduit 138 may not be provided on the openable door 152 (see e.g.,FIGS. 29B, 48, and 49 ). As an example, the embodiment ofFIG. 29B shows theinlet conduit 138 positioned above theopenable door 152. As another example, the embodiment ofFIGS. 48 and 49 shows theinlet conduit 138 positioned below theopenable door 152. In these embodiments, theinlet conduit 138 does not move when thedoor 152 is moved. Accordingly, when thedoor 152 is opened (e.g., pivoted) to empty collected dirt and debris, theinlet conduit 138 maintains its position. This positioning of theinlet conduit 138 may be used with any one or more other configurations of an element of a hand vacuum cleaner as discussed herein. - Optionally,
hand vacuum cleaner 100 may be removably mountable on a base (e.g., a surface or floor cleaning head and an upright housing or wand that is pivotally mounted to the surface cleaning head) so as to form, for example, an upright vacuum cleaner or a stick vacuum cleaner, or, if the base is a canister body, then it may be part of a canister vacuum cleaner. The base and the hand vacuum cleaner may provide a surface cleaning apparatus that is a vacuum cleaner, a wet-dry vacuum cleaner and the like. As exemplified inFIGS. 5 and 32 , the base of surface cleaning apparatus may include asurface cleaning head 178 and anelongate wand 180 that can be connected tohand vacuum cleaner 100 so as to provide a stick vacuum cleaner. In this configuration, the surface cleaning apparatus may be used to clean a floor or other surface in a manner analogous to a conventional upright-style vacuum cleaner. -
Inlet end 174 ofinlet conduit 138 may include any suitable connector that is operable to connect to, and preferably detachably connect to, a hose, cleaning tool, the upright section (e.g., rigid wand) of a base of an upright or stick vacuum cleaner) or other accessory. Optionally, in addition to providing an air flow connection,inlet conduit 138 may also include an electrical connection. Providing an electrical connection may allow cleaning tools, accessories and the like that are coupled toinlet conduit 138 to be powered byhand vacuum cleaner 100. For example,hand vacuum cleaner 100 can be used to provide both power and suction to surface cleaning head 178 (seeFIGS. 5 and 32 ). As exemplified inFIGS. 1 and 28 ,inlet conduit 138 may include an electrical coupling in the form of afemale socket member 182, and a corresponding male prong member may be provided on the wand, hose, cleaning tool and/or accessory that is connected toinlet conduit 138. -
Clean air outlet 108 may be provided in any manner that allows the air flow to exithand vacuum cleaner 100. In the illustrated embodiment ofFIGS. 1-4 ,clean air outlet 108 is provided as part of themain body 102 and configured as a grill. Aclean air outlet 108 may be provided on each lateral side ofmain body 102. In this embodiment, the grill is oriented so that air exitingclean air outlet 108 travels laterally outward frommain body 102. This may ensure that the exhausted air is directed away from a user's hand when they are holdinghandle 200 rearward of theclean air outlet 108. Alternatively, as exemplified inFIG. 33 ,clean air outlet 108 may be a grill provided onupper end 114 ofhand vacuum cleaner 100 so that the exhausted air travels generally upwardly fromupper end 114. Alternatively, as exemplified inFIG. 38 ,clean air outlet 108 may be a plurality of openings provided atrear end 112 ofhand vacuum cleaner 100 so that the exhausted air travels generally rearwardly fromrear end 112. - In operation, after activating
suction motor 118, dirty air entershand vacuum cleaner 100 throughdirty air inlet 106 and is directed throughinlet conduit 138 tocyclone air inlet 136. As exemplified,cyclone air inlet 136 directs the dirty air flow intocyclone chamber 124 in a tangential direction to promote cyclonic motion incyclone chamber 124. After enteringcyclone chamber 124, the air rotates and exitscyclone chamber 124 throughcyclone air outlet 140. Dirt particles and other debris is disentrained (i.e., separated) from the dirty air flow as the dirty air flow rotates incyclone chamber 124 while travelling fromcyclone air inlet 136 tocyclone air outlet 140. Some (e.g., the heavier) dirt may be separated from the inflow air stream by gravity due to the air flow rate decreasing as the air enterscyclone chamber 124 and/or a change in the direction of the air flow as it enters or travels throughcyclone chamber 124. Additional dirt and debris may be separated bymesh screen 146 ofvortex finder 144 due to filtration. At least some of the disentrained dirt particles and debris may be discharged fromcyclone chamber 124 throughdirt outlet 142 intodirt collection chamber 126 external tocyclone chamber 124, where the dirt particles and debris may be collected and stored untildirt collection chamber 126 is emptied. - From
cyclone air outlet 140, the air flow may be directed intopre-motor filter housing 160 where it is drawn throughpre-motor filter 162. From the downstream end ofpre-motor filter housing 160, the air flow may be directed intosuction motor housing 119, drawn through thesuction motor 118 and then discharged fromhand vacuum cleaner 100 throughclean air outlet 108. Prior to exitingclean air outlet 108, the treated air may pass throughpost-motor filter 172, which may be one or more layers of filter media. - In the illustrated embodiment of
FIG. 2 ,motor axis 122 is substantially perpendicular tocyclone axis 134. As exemplified,suction motor 118 may be positioned so thatmotor axis 122 intersectspre-motor filter housing 160. Alternatively, or in addition,motor axis 122 may extend through a central portion of thepre-motor filter housing 160 and/or the cyclone chamber 124 (see e.g.,FIG. 29B ). Alternatively, as exemplified inFIG. 6 ,motor axis 122 may be substantially parallel tocyclone axis 134. As described subsequently herein, various alternative positions and orientations ofsuction motor 118 are possible. -
Suction motor housing 119 andpre-motor filter housing 160 may have various positional arrangements. As exemplified inFIG. 2 ,main body 102 may be configured such thatsuction motor housing 119 is located rearward of thepre-motor filter housing 160 and, preferably, axially aligned with thepre-motor filter housing 160 such that air exitingpre-motor filter housing 160 may travel generally linearly tosuction motor 118. Optionally, as exemplified inFIG. 33 ,motor axis 122 may be generally co-axial withcyclone axis 134. This may help provide a desirable hand feel to a user. Alternatively, as exemplified inFIG. 7 ,suction motor 118 may be positioned belowpre-motor filter housing 160 whenhand vacuum cleaner 100 is oriented with theupper end 114 above thelower end 116. In this configuration, air exitingpre-motor filter housing 160 may be drawn downwardly tosuction motor 118. -
Hand vacuum cleaner 100 can include ahandle 200. Various options for a handle configuration and positioning are discussed. Any such handle could be used by itself or in combination with one or more of the other aspects set out herein including one or more of the enlarged dirt collection chamber or region, the power source, the position of the handle, the position of the first energy storage pack, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor, the position of the post-motor filter and an access pivot. - Handle 200 may have various positional arrangements and configurations, which may improve the ergonomics of
hand vacuum cleaner 100. As an example, handle 200 may be located atrear end 112 of hand vacuum cleaner 100 (see, e.g.,FIGS. 54, 58 and 59 ). As another example, handle 200 may be located atupper end 114 of hand vacuum cleaner 100 (see, e.g.,FIGS. 61 and 63 ). As yet another example, handle 200 may be located atlower end 116 of hand vacuum cleaner 100 (see, e.g.,FIGS. 43, 44 and 48 ). - Optionally, handle 200 may be removable from
main body 102. For example,FIGS. 16-17 exemplify aremovable handle 200 mounted belowbody portion 120. Handle 200 can be removably mounted tomain body 102 in any suitable fashion (e.g., dove-tail locking members, clips, etc.). Removinghandle 200 may facilitate charging or replacement ofenergy storage members FIG. 17 ). - The
handle 200 may have various configurations. For example, in the illustrated embodiments ofFIGS. 1-55 , handle 200 is configured as a pistol grip type handle that extends upwardly and forwardly along a handle axis 202 (e.g.,FIGS. 2 and 55 ) between upper and lower handle ends 204, 206, whenhand vacuum cleaner 100 is oriented so thatupper end 114 is above thelower end 116. It will be appreciated that handle 200 may consist of a pistol grip handle (see for exampleFIGS. 2, 29 and 54 ) or it may comprise a pistol grip section (see for exampleFIG. 62 ). - As exemplified in
FIGS. 59-61 , handle 200 may be configured as a stick or linearly extending handle. A linearly extending handle may be mounted to themain body 102 or theair treatment assembly 104. As exemplified inFIG. 59 , handle 200 includes agrip portion 214 that extends rearwardly fromrear end 112. As exemplified inFIG. 61 ,grip portion 214 extends rearwardly from the upper end of a mountingportion 216.FIG. 61 shows mounting portion 216 connected to the upper end ofpre-motor filter housing 160.FIG. 63 shows thehandle 200 mounted to the upper end of themain body 102.FIG. 64 show mounting portion 216 connected to the upper surface ofair treatment assembly 104. - As exemplified in
FIGS. 62, 65 and 66 , ahandle 200 that is mounted to an upper portion of the hand vacuum cleaner may include apistol grip portion 218 extending downwardly from anupper handle portion 220. As exemplified,pistol grip portion 218 is positioned rearward ofmain body 102.FIG. 62 showsupper handle portion 220 mounted to the upper end ofpre-motor filter housing 160. In this embodiment, a continuousfinger grip area 210 is formed (i) betweenpistol grip portion 218 and the rear end ofmain body 102 and (ii) betweenupper handle portion 220 and the upper end ofmain body 102.FIG. 65 exemplifiesupper handle portion 220 mounted to the upper surface ofair treatment assembly 104.FIG. 66 exemplifiesupper handle portion 220 connected to the upper end ofsuction motor housing 119. As exemplified inFIGS. 65 and 66 , afinger grip area 210 may be formed betweenpistol grip portion 218 and the rear end ofsuction motor housing 119. - Although the illustrated embodiments of
FIGS. 62, 66 and 66 exemplify apistol grip portion 218 that extends straight down fromupper handle portion 220,pistol grip portion 218 may extend downwardly and rearwardly from upper handle portion 220 (e.g., at an angle between 0 and 40°). - One or more portions of the
handle 200 may be attached to the hand vacuum cleaner. The handle may be attached to the hand vacuum cleaner directly or by one or more bridge portions. For example, the upper or lower end, or both the upper and lower ends, of thehandle 200 may be attached to the hand vacuum cleaner. - In addition, the handle may be mounted, directly or by one or more bridge portions, to the lower end of the hand vacuum cleaner, the rear end of the hand vacuum cleaner and/or an upper end of the hand vacuum cleaner.
- As exemplified in
FIG. 2 ,upper handle end 204 is mounted to the lower side ofbody portion 120 and a rearwardly extendingbridge portion 208 extends from the rear side ofair treatment assembly 104 tolower handle end 206. As exemplified inFIG. 29 , only theupper handle end 204 is mounted to a lower end of themain body 102. As exemplified inFIG. 55 ,upper bridge portion 212 andlower bridge portion 208 connect the upper and lower ends of thehandle 200 to the rear end wall of themain body 102. As exemplified inFIG. 63 , thehandle 200 is secured at each end of thehand grip portion 222. As exemplified inFIG. 60 , thehandle 200 is attached directly to the rear end wall of thehand vacuum cleaner 100. As exemplified inFIG. 61 , thehandle 200 is attached to the upper end of thehand vacuum cleaner 100. As exemplified inFIG. 63 , handle 200 is configured as a C-shape handle (similar to the handles commonly found at the top of briefcases or toolboxes) and is secured to the upper end of the hand vacuum cleaner by two bridge portions. - In any configuration, the handle, which may be a
pistol grip handle 200, may be mounted at various locations to thelower end 116 ofhand vacuum cleaner 100. For example,upper handle end 204 may be mounted to the lower side of pre-motor filter housing 160 (see, e.g.,FIGS. 29 and 33, 34 ). Accordingly, handleaxis 202 may extend through thepre-motor filter housing 160 and optionally the pre-motor filter 162 (see e.g.,FIGS. 29A-29B ). Alternatively,upper handle end 204 may be mounted to the lower surface of suction motor housing 119 (see, e.g.,FIGS. 39, 42 and 52 ). Alternatively, or in addition,upper handle end 204 may be mounted to the lower side ofair treatment assembly 104, such as a lower surface of the portion of the dirt collection region or chamber underlying the pre-motor filter (see, e.g.,FIGS. 29A, 29B , and/or a lower portion of an air treatment chamber (see, e.g.,FIGS. 40, 44 and 47 ). - As exemplified in
FIGS. 29A and 29B , theupper handle end 204 is positioned below aportion 125 of theair treatment member 104 that underlies thepre-motor filter housing 160. As exemplified, theportion 125 of theair treatment member 104 is positioned between theupper handle end 204 and thepre-motor filter housing 160. As exemplified inFIGS. 29A and 29B , avertical projection 133 of the upper handle end of the pistol grip handle 200 extends through thepre-motor filter housing 160. Accordingly, handleaxis 202 may extend through theportion 125 of theair treatment member 104 that is positioned between theupper handle end 204 and the pre-motor filter housing 160 (see e.g.,FIGS. 29A-29B ). These configurations of thehand vacuum cleaner 100 and the pistol grip handle 200 may improve ergonomics and/or expand the volume of theair treatment member 104 without increasing overall vacuum cleaner size. - In embodiments wherein
upper handle end 204 is mounted to the lower side ofpre-motor filter housing 160 or theportion 125 of theair treatment member 104 is positioned between theupper handle end 204 and thepre-motor filter housing 160, the lower side of the suction motor housing may be generally aligned with the lower side of the cyclone assembly as exemplified inFIGS. 29, 29A, 29B . - In the embodiment of
FIG. 29A , theportion 125 of theair treatment member 104 that is positioned between theupper handle end 204 and thepre-motor filter housing 160 is a portion ofdirt collection region 127. As previously discussed, in this embodiment,dirt collection region 127 is internal to (i.e., within) the air treatment chamber (e.g., cyclone chamber 124). In the embodiment ofFIG. 29B , theportion 125 of theair treatment member 104 that is positioned between theupper handle end 204 and thepre-motor filter housing 160 is a portion ofdirt collection chamber 126. As previously discussed, in this embodiment, thedirt collection chamber 126 is external to the air treatment chamber (e.g., cyclone chamber 124). - In some embodiments, handle 200 may be mounted at a location that is radially outward of suction motor housing 119 (e.g., see
FIGS. 39, 42 and 66 ). Alternatively, handle 200 may be mounted atrear end 112 ofhand vacuum cleaner 100. As exemplified inFIGS. 59 and 60 , handle 200 may be configured as a stick-type handle that extends rearwardly and downwardly from the rear surface ofbody portion 120. In an alternative embodiment (not shown), stick type handle 200 may extend substantially perpendicularly from the rear surface ofbody portion 120. - The handle may be mounted at various locations to
upper end 114 ofhand vacuum cleaner 100. For example, handle 200 may be mounted to the upper end of pre-motor filter housing 160 (see, e.g.,FIGS. 61-63 ). Alternatively, handle 200 may be mounted to the upper side of air treatment assembly 104 (see, e.g.,FIGS. 64-65 ). Alternatively, handle 200 may be mounted to the upper end of suction motor housing 119 (see, e.g.,FIG. 66 ). - A finger grip area may be provided between the handle (the hand grip portion) and the hand vacuum cleaner (the main body and/or the air treatment assembly). As exemplified in
FIG. 2 , an enclosedfinger grip area 210 for receiving the fingers of a user is formed betweenhandle 200 and the rear side ofair treatment assembly 104. It will be appreciated thatbridge portion 208 need not be provided and therefore thefinger grip area 210 may be open. - As exemplified in
FIG. 55 , spaced apart and rearwardly extendingbridge portions body portion 120 tolower handle end 206 andupper handle end 204, respectively. In this configuration,finger grip area 210 for receiving the fingers of a user is formed betweenhandle 200 and the rear side ofbody portion 120. As exemplified inFIG. 55 ,body portion 120 may be positioned forward offinger grip area 210. - As exemplified in
FIGS. 61 and 64 , afinger grip area 210 may be formed betweengrip portion 214 and the hand vacuum cleaner, e.g., between the upper ends ofsuction motor housing 119 andpre-motor filter housing 160. In the illustrated embodiment ofFIG. 63 , afinger grip area 210 is formed between agrip portion 222 ofhandle 200 and the upper ends ofsuction motor housing 119 andpre-motor filter housing 160. - As exemplified in
FIGS. 51A, 67 and 68 , some or all of a dirt collection region or an external dirt collection chamber may occupy a volume that is below an air treatment chamber and is forward of a handle that is situated below the main body. Accordingly, the dirt storage capacity of a hand vacuum cleaner may be increased without increasing a volume defined by the length (forward to back) and the height of the hand vacuum cleaner. - This aspect could be used by itself or in combination with one or more of the other aspects set out herein including one or more of the handle, the power source, the position of the handle, the position of the first energy storage pack, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor, the position of the post-motor filter and an access pivot.
- As exemplified, a
portion 129 ofdirt collection chamber 126 may extend downwardly fromair treatment chamber 124. Theportion 129 is shown spaced forward ofhandle 200 such that there is an open volume orfinger gap 210 between thepistol grip portion 250 of thehandle 200 and the rear end of theportion 129 ofdirt collection chamber 126.Pistol grip portion 250 refers to the region ofhandle 200 which may engage the user's fingers. - Optionally, at least a portion of the
dirt collection chamber 126 is located at an elevation that is below alower end 121 of thebody portion 120. In some embodiments, at least 50% (e.g., 50%, 60%, 70%, 80%, 90% or more, e.g., all) of thedirt collection chamber 126 is located at an elevation that is below thelower end 121 of thebody portion 120. As an example, the illustrated embodiment ofFIG. 51A shows about 80% of thedirt collection chamber 126 located at an elevation that is below thelower end 121 ofbody portion 120. As another example, the illustrated embodiment ofFIG. 68 shows all (i.e., 100%) of thedirt collection chamber 126 located at an elevation that is below thelower end 121 ofbody portion 120. - In some embodiment, the portion of the dirt collection region located at an elevation below the
lower end 121 ofbody portion 120 has a length that is at least half (e.g., 50%, 60%, 70, 80%, 90%, or more) the length of thepistol grip portion 250 As an example, the illustrated embodiment ofFIG. 68 shows the length of theportion 129 being about the same as the length ofpistol grip portion 250. - In some embodiments, the lower end of
portion 129 andlower handle end 206 may be at the same elevation. In these embodiments, theportion 129 of thedirt collection chamber 226 and thehandle 200 may cooperate to support thehand vacuum cleaner 100 in a horizontal orientation when it is placed on a resting surface (i.e., thehandle 100 andportion 129 may act together as a stand). Alternatively, or in addition, thelower handle end 206 may be located proximate to the lower end of theportion 129 of the dirt collection chamber 126 (e.g., seeFIGS. 51A and 67 ). - The
dirt collection chamber 126 has a centrally positioned dirt collection chamber axis 131 (seeFIGS. 51A and 68 ). The dirtcollection chamber axis 131 extends from an upper end of thedirt collection chamber 126, through thedirt collection chamber 126, to a lower end of thedirt collection region 126. In the embodiment ofFIG. 68 , the dirtcollection chamber axis 131 is generally parallel to thehandle axis 202. This configuration of thehand vacuum cleaner 100 and the pistol grip handle 200 may improve ergonomics. In other embodiments, the dirtcollection chamber axis 131 may extend at an angle relative to the handle axis 202 (e.g.,FIG. 51A ). - In some embodiments, the
lower handle end 206 may be a stand forhand vacuum cleaner 100. As exemplified inFIG. 29B , the lower end handleend 206 engages a support surface 252 (e.g., a table, bench, desk, countertop, floor, etc.) to maintain the hand vacuum cleaner in a horizontal orientation. For example, the components of thehand vacuum cleaner 100 may be positioned to balance the weight on opposite sides of thehandle 200. In the embodiment ofFIG. 29B , the footprint of energy storage pack 302 (provided at the lower handle end 206) improves stability. - The
portion 129 of thedirt collection chamber 126 that extends downwardly of thebody portion 120 can have any suitable configuration, such as ellipsoid, cylindrical, frustoconical, for example. In the illustrated embodiment ofFIG. 67 , thedirt collection chamber 126 is generally cuboid. A cuboid configuration may provide maximal dirt collection volume for a given footprint. - The lower end of the
dirt collection chamber 126 may be openable (e.g., to release collected dirt and debris held therein). As exemplified inFIGS. 51A and 68 , the lower end ofdirt collection chamber 126 includes anopenable door 152. Theopenable door 152 may be movably connected (e.g., pivotally openable or removably mounted) todirt collection chamber 126 using any suitable mechanism, including a hinge or other suitable device. Optionally,openable door 152 may be secured in the closed position using any suitable type of locking mechanism. As exemplified inFIG. 67 , thedoor 152 may be held in the closed position by alatch 154 that may be released by a user. - As shown in the embodiment of
FIGS. 51A and 68 , thedirt collection chamber 126 is external tocyclone chamber 124.Cyclone chamber 124 and dirt collection chamber 16 are fluid connected viadirt outlet 142. That is, dirt separated from the air stream can pass from thecyclone chamber 124, through thedirt outlet 142, to thedirt collection chamber 126. As previously discussed, in alternative embodiments, dirt collection chamber(s) may be internal to the cyclone chamber and configured as a dirt collection area or region within the cyclone chamber. - As discussed previously, it will be appreciated that the
air treatment chamber 124 and thedirt collection chamber 126 may be concurrently openable. -

Energy storage member may include, for example, batteries, supercapacitors or the like. The energy storage member may be provided in one or more energy storage packs 300, 302, which comprise one or more batteries, supercapacitors or the like. As used herein, “energy storage pack” 300, 302 may refer to a single energy storage member or a plurality of energy storage members that are secured together, such as by an energy storage member housing. Any such energy storage member housing known in the art may be used. - The energy storage members may be permanently mounted in
hand vacuum cleaner 100 and rechargeable in-situ, and/or removable from hand vacuum cleaner 100 (e.g., one or more of the energy storage packs may be removable mounted to the hand vacuum cleaner). Alternatively, or in addition, power may be supplied tosuction motor 118 by an electrical cord (e.g., seeelectrical cord 306 ofFIG. 13 ) connected to handvacuum cleaner 100. The electrical cord can be connected to mains power at a standard wall electrical outlet. - In the illustrated embodiment of
FIGS. 1-4 , power is supplied tosuction motor 118 by a firstenergy storage pack 300. As exemplified inFIG. 2 , an optional second or supplementalenergy storage pack 302 may be provided. In some embodiments, multiple supplemental energy storage packs 302 may be provided (e.g., see the illustrated embodiments ofFIGS. 20, 29A and 29B in which two supplemental energy storage packs 302 are provided). One or more supplemental energy storage packs 302 may be provided to, for example, increase the power supplied tosuction motor 118 and/or lengthen the durationhand vacuum cleaner 100 can operate with without recharging. - Removing first and/or second energy storage packs 300, 302 may facilitate the replacement of discharged batteries within first and second energy storage packs 300, 302. Energy storage packs may be removable connected to hand
vacuum cleaner 100 in any suitable fashion. As an example,FIG. 2 showsrecesses body portion 120 for receiving corresponding first and second energy storage packs 300, 302. As indicated by the arrows, firstenergy storage pack 300 is removable upwardly fromrecess 188, and secondenergy storage pack 302 is removable rearwardly fromrecess 190. As another example,FIGS. 19 and 20 show arecess 192 provided forward ofpre-motor filter housing 160 for receiving firstenergy storage pack 300. As indicated by the arrow, firstenergy storage pack 300 is removable upwardly fromrecess 192. - Alternatively, as exemplified in
FIG. 6 , firstenergy storage pack 300 may connect directly to the exterior of body portion 120 (i.e., not received within a body recess). In the illustrated embodiment, top and rear surfaces of firstenergy storage pack 300 form part of the exterior of hand vacuum clearer 100 when first energy packs 300 is connected. In alternative embodiments, as exemplified inFIG. 9 , first and second energy packs 300, 302 may be permanently connected tohand vacuum cleaner 100. - In the illustrated embodiment of
FIG. 2 ,hand vacuum cleaner 100 includes an optionalonboard power supply 304.Power supply 304 is electrically connected to first and second energy storage packs 300, 302.Power supply 304 converts direct current (received from mains power) into alternating current and then supplies that alternating current to first and secondenergy storage members power supply 304 is permanently connected tohand vacuum cleaner 100. For example,FIG. 2 showspower supply 304 fully housed inbody portion 120. In some embodiments,power supply 304 may be removable fromhand vacuum cleaner 100. - First and second energy storage packs 300, 302 may be recharged in-situ by connecting one end of an electrical cord to cord port 184 (
FIG. 1 ) while the other end of the electrical cord is connected to mains power at a standard wall electrical outlet.Cord port 184 may be provided in any suitable location, although it may be convenient to locatecord port 184 proximate the energy storage member(s). As an example,FIG. 1 showscord port 184 provided onbody portion 120 proximaterear end 112 ofhand vacuum cleaner 100. As another example,FIG. 30 showscord port 184 provided on the rear side ofhandle 200. As exemplified inFIG. 13 ,cord port 184 is located atlower handle end 206. - As exemplified in
FIG. 13 ,cord port 184 may be connected to a removable electrical cord 306 (e.g., female socket member ofcord port 184 mates with male socket member of electrical cord 306).Electrical cord 306 can be connected to recharge one or more of the on-board energy storage members. Alternatively,electrical cord 306 can be connected to supply power tosuction motor 118 and other electrical components of hand vacuum cleaner 100 (e.g., for corded use). - Optionally, as exemplified in
FIGS. 14-15 ,electrical cord 306 may be housed inhandle 200. As shown inFIG. 15 ,electrical cord 306 can be extended fromlower handle end 206 so that it can be connected to mains power at a wall electrical outlet. Preferably, it is its “non-extended” state,electrical cord 306 is fully housed in handle 200 (i.e., no part ofelectrical cord 306 sticks out from lower handle end 206). In the illustrated embodiment,electrical cord 306 is a resilient coiled wire that returns to its natural state when a supplied tension is removed. Optionally, electrical cord may be a low voltage cord (e.g., 9V). In such a case, a power supply may be provided remotely (such as in a wall plug) so as to provide low voltage power toelectrical cord 306. It will be appreciated that, in such an embodiment, the hand vacuum cleaner may not include apower supply 304. - In alternative embodiments, a cord reel (not shown) may be provided to facilitate retraction of
electrical cord 306 back intohandle 200. -
Electrical cord 306 may be electrically connected (either directly or indirectly) to any (or all) of energy storage packs 300, 302 and/orpower supply 304. As exemplified inFIG. 14 ,electrical cord 306 is directly connected to firstenergy storage pack 300. As exemplified inFIGS. 21-23 ,electrical cord 306 is directly connected topower supply 304. -
Hand vacuum cleaner 100 may include apower switch 308 that is provided to selectively control the operation of the suction motor (e.g., either on/off or variable power levels or both), for example by establishing a power connection betweenenergy storage pack suction motor 118.Power switch 308 may be provided in any suitable configuration and location, including a button, rotary switch, sliding switch, trigger-type actuator, and the like. As an example, the illustrated embodiment ofFIG. 2 showspower switch 308 provided as a trigger-type actuator. As another example, the illustrated embodiment ofFIG. 30 showspower switch 308 provided as a button located on rear end ofsuction motor housing 119. - As described subsequently, first and second energy storage packs 300, 302 and
power supply 304 may have various positional arrangements, which may improve the ergonomics of the hand vacuum cleaner 100 (e.g., reduced weight, better weight balance, or greater portability). -
Hand vacuum cleaner 100 may have ahandle 200 positioned on a lower end of themain body 102 such thatmain body 102 may overlie part or all offinger grip area 210 and/or handle (e.g., upper handle end 204). This aspect could be used by itself or in combination with one or more of the other aspects set out herein including one or more of the handle, the enlarged dirt collection chamber or region, power source, the position of the first energy storage pack, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor, the position of the post-motor filter and an access pivot. Accordingly, a hand vacuum cleaner using any aspect discussed herein may have amain body 102 that overlies part or all offinger grip area 210 and/or thehandle 200. For example, at least 50% (e.g., 50%, 60%, 70%, 80%, 90%, or more) ofmain body 102 may overlieupper handle end 204. - As used herein, Element A is said to “overlie” Element B if, when viewed from, e.g., a top plan view with
hand vacuum cleaner 100 orientedupper end 114 abovelower end 116, at least a portion of the length of element A (in the forward/rearward direction) overlaps the length of Element B (in the forward/rearward direction). For example, if it is said that 50% of element A overlies Element B, it means that 50% of Element A's length overlaps Element B when viewed from the top plan. “Overlie” does not necessarily mean directly overlie. For example, Element A still overlies element B even when an Element C is positioned between Elements A and B. Accordingly, in the embodiment ofFIG. 2 ,body portion 120 overlies all of the upper end of thehandle 200 and all of thefinger grip area 210. The term “underlie” is intended to have the same meaning discussed above for “overlie”, but in reverse. - A hand vacuum cleaner using any one or more aspects discussed herein, including one or more of the other aspects set out herein including one or more of the handle, the enlarged dirt collection chamber or region, the power source, the position of the handle, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor, the position of the post-motor filter and an access pivot, may have a first
energy storage pack 300 positioned at any location discussed herein. - First
energy storage pack 300 may be provided in various positions. For example, firstenergy storage pack 300 may be positioned in body portion 120 (see, e.g.,FIGS. 2, 7, 9, and 49 ). The following discussion sets out various possible positions of firstenergy storage pack 300 with respect to other components of the hand vacuum cleaner. While the position of firstenergy storage pack 300 with respect to other components is discussed separately with respect to each other component, it will be appreciated that any embodiment of a hand vacuum cleaner may utilize the positioning of the firstenergy storage pack 300 with respect one or more of the other components discussed herein. - First
energy storage pack 300 may be removably mounted to the hand vacuum cleaner. Removing firstenergy storage pack 300 may facilitate replacement of an expired battery with a charged one. Alternately, firstenergy storage pack 300 may be permanently connected to the hand vacuum cleaner. - First
energy storage pack 300 may be positioned rearward of the air treatment assembly, e.g., inmain body 102, or forward of cyclone chamber 124 (see, e.g.,FIGS. 20-26 ) and in such a position, it may be mounted to theair treatment assembly 104 or a portion of themain body 102. - First
energy storage pack 300 may be positioned rearward of theportion 125 of theair treatment assembly 104 that underlies the pre-motor filter housing 160 (see, e.g.,FIG. 29B ). As exemplified, the firstenergy storage pack 300 is aligned with theportion 125 such that a projection of some or all of the vertical height of the firstenergy storage pack 300 may intersect theportion 125. In such a position, the firstenergy storage pack 300 may be mounted to theair treatment assembly 104 and/or a portion of themain body 102. As previously discussed, theportion 125 of theair treatment assembly 104 underlying thepre-motor filter housing 160 may be one of (i) aportion 125 of adirt collection region 127 that is internal to the air treatment chamber 124 (e.g.,FIG. 29A ), or (ii) aportion 125 of adirt collection chamber 126 that is external to the air treatment chamber 124 (e.g.,FIG. 29B ). - Alternately, first
energy storage pack 300 may be located at theupper end 114 of the hand vacuum cleaner (see e.g.,FIG. 29A ). The illustrated embodiment ofFIG. 29A shows the firstenergy storage pack 300 mounted to the upper end ofpre-motor filter housing 160. In alternative embodiments, depending on its position, the firstenergy storage pack 300 may be mounted to the upper end of theair treatment assembly 104, the upper end ofsuction motor housing 119 and/or another portion of themain body 102. - As exemplified by the broken lines in

In some embodiments, the firstenergy storage pack 300 extends along at least 50% (50%, 60%, 70%, 80%, 90%, or more) of the forward/rearward length ofhand vacuum cleaner 100. As an example, the embodiment ofFIG. 29A shows the first energy storage pack 300 (in solid lines) extending along about 50% of the forward/rearward length ofhand vacuum cleaner 100. With respect topre-motor filter housing 160, firstenergy storage pack 300 may be positioned directly or indirectly rearward of pre-motor filter housing 160 (a horizontal plane may extend through thepre-motor filter 162 and the firstenergy storage pack 300 as exemplified inFIGS. 6, 49, 55, 56 and 60 ) and may be located partially or fully above or below thereof, directly or indirectly forward of pre-motor filter housing 160 (see, e.g.,FIGS. 20-26 ) and may be located partially or fully above or below thereof, directly or indirectly above pre-motor filter housing 160 (see, e.g.,FIGS. 27 and 29A ), directly or indirectly belowpre-motor filter housing 160. For example, firstenergy storage pack 300 may be located rearward and vertically spaced from pre-motor filter housing 160 (see, e.g.,FIG. 42 ). - Optionally, first
energy storage pack 300 may be positioned partially or fully in handle 200 (see, e.g.,FIG. 13 ), and may be removably positionable therein. - Optionally, first
energy storage pack 300 may be positioned at lower handle end 206 (e.g., seeFIGS. 28, 33, 34, 50, and 52 ). Firstenergy storage pack 300 may be mounted tolower handle end 206 in any suitable manner. As exemplified inFIG. 28 , firstenergy storage pack 300 may be removably mounted tolower handle end 206 via a lockingmember 224. For example, firstenergy storage pack 300 may be removably mounted tolower handle end 206 using dove-tail mounting members, mechanical fasteners such as screws, etc. - Optionally, first
energy storage pack 300 may be positioned abovehandle 200. For example, it may be provided inmain body 102 at a lower end thereof directly overlying the upper end of the handle (e.g., seeFIG. 2 ), inmain body 102 at an upper end thereof overlying part or all of the upper end of the handle and/or the finger grip area (e.g., seeFIGS. 6-12, 14 ), rearward of the handle (e.g., seeFIGS. 36 and 49 ) or underlying the handle (e.g., seeFIG. 57 ). - Optionally, first
energy storage pack 300 may be positioned exterior to themain body 102, e.g., betweenupper handle end 204 and suction motor housing 119 (e.g., seeFIGS. 41 and 43 ) and/or betweenupper handle end 204 andpre-motor filter housing 160 and/or betweenupper handle end 204 and the air treatment assembly. - Regardless of whether first
energy storage pack 300 is internal or external the main body, at least a portion of firstenergy storage pack 300 may overlie upper handle end 204 (see, e.g.,FIGS. 2, 6-8, 11, 12, 14, 18, and 41-44 ). For example, at least 50% (e.g., 50%, 60%, 70%, 80%, 90%, or more) of firstenergy storage pack 300 may overlieupper handle end 204. As an example, the illustrated embodiment ofFIG. 6 shows about 50% of firstenergy storage pack 300 overlyingupper handle end 204. As another example, the illustrated embodiment ofFIG. 11 shows 100% of firstenergy storage pack 300 overlyingupper handle end 204. - Alternately, or in addition, at least a portion of first
energy storage pack 300 may overlie finger grip area 210 (see, e.g.,FIGS. 10, 12 and 18 ). For example, at least 50% (e.g., 50%, 60%, 70%, 80%, 90%, or more) of firstenergy storage pack 300 may overliefinger grip area 210. As an example, the illustrated embodiment ofFIG. 18 shows about 50% of firstenergy storage pack 300 overlyingfinger grip area 210. -
Hand vacuum cleaner 100 may include an energystorage member recess 228. Arecess 228 may be provided if the firstenergy storage pack 300 is removably mountable to the hand vacuum cleaner. The recess may be provided in themain body 102, the air treatment assembly or as part of the handle. As exemplified inFIGS. 41-47 ,recess 228 is provided atupper handle end 204.

perforated motor collar 186 may be positioned aroundsuction motor 118 to permit the air flow to travel in a radially outward direction fromsuction motor 118 toward annular post-motor filter 172 (which provides clean air outlet 108). - A hand vacuum cleaner using any one or more of the aspects discussed herein including one or more of the handle, the enlarged dirt collection chamber or region, the power source, the position of the handle, the position of the first energy storage pack, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor and an access pivot, may have one or more
post-motor filters 172 and, if so, the one or morepost-motor filters 172 may be positioned at any location discussed herein. While the position of the one or morepost-motor filters 172 with respect to other components is discussed separately with respect to each other component, it will be appreciated that any embodiment of a hand vacuum cleaner may utilize the positioning of the one or morepost-motor filters 172 with respect to one or more of the other components discussed herein. - With respect to
suction motor 118,post-motor filter 172 may be positioned directly or indirectly forward of suction motor 118 (see, e.g.,FIGS. 8 and 9 ) and may be located partially or fully above or below thereof, directly or indirectly rearward of suction motor 118 (see, e.g.,FIGS. 2, 6, 11, 18, 20, 36, and 42 ) and may be located partially or fully above or below thereof, directly or indirectly below suction motor 118 (see, e.g.,FIGS. 10, 26, 56 and 57 ) or directly or indirectly above suction motor 118 (see, e.g.,FIGS. 24 and 57 ). - If two
pre-motor filters 172 are provided, then each may be in the same location or optionally each may be at any location discussed previously. For example, as exemplified inFIG. 57 , twopost-motor filters 172 are provided wherein onepost-motor filter 172 is positioned abovesuction motor 118 and the otherpost-motor filter 172 is positioned belowsuction motor 118. - In the illustrated embodiment of
FIG. 34 , an elongatepost-motor filter 172 is provided belowsuction motor 118 andpre-motor filter housing 160. Elongatepost-motor filter 172 may extend longitudinally (in a forward/rearward direction) so that at least a portion ofpre-motor filter housing 160 andsuction motor 118 overlie elongatepost-motor filter 172. As exemplified inFIG. 34 , nearly 100% ofpre-motor filter housing % suction motor 118 overlie elongatepost-motor filter 172. - As exemplified in
FIGS. 28 and 29 ,suction motor 118 may be surrounded by an annularpost-motor filter 172. As with the energy storage pack, it will be appreciated thatpost-motor filter 172 may be arcuate in shape and may surround, e.g., at least 50% (e.g., 50%, 60%, 70%, 80%, 90%, or more) ofsuction motor 118.Post-motor filter 172 may be a single contiguous arcuate member or a plurality of discrete arcuate members that may abut (e.g., two semi-circular post-motor filters 172) or which may be spaced apart. - A hand vacuum cleaner using any one or more of the aspects discussed herein including one or more of the handle, the enlarged dirt collection chamber or region, the power source, the position of the handle, the position of the first energy storage pack, the position of the second energy storage pack, the first and second energy storage packs on opposed lateral sides of the handle, the position of the power supply, the position of the suction motor, and the position of the post-motor filter may have one or
more pivots 117 and, if so, the one ormore pivots 117 may be positioned at any location discussed herein. It will be appreciated that any embodiment of a hand vacuum cleaner may utilize the positioning of the one ormore pivots 117, such as so provide access to any one or more of the other components discussed herein. - In accordance with this aspect, the hand vacuum cleaner has two portions which are rotatably mounted, e.g., pivotally mounted, to each other. It will also be appreciated that, in addition, the two portions may also be removably connected to each other. Typically, the dirty air inlet or nozzle of a hand vacuum cleaner is provided at the front end of the hand vacuum cleaner. Therefore, the two portions may be referred to as a forward portion and a rearward portion.
- A hand vacuum cleaner has a plurality of operating components. The operating components comprise one or more air treatment members and one or more suction motors. The air treatment members may be one or more air treatment chambers, one or more a pre-motor filters and one or more post-motor filters. For example, a single air treatment chamber may be provided, which may be a cyclone chamber or a non-cyclonic momentum separator. Alternately, two air treatment stages may be provided, each of which may comprise one or more air treatment chambers, each of which may be a cyclone chamber or a non-cyclonic momentum separator. Accordingly, the hand vacuum cleaner may comprise a first air treatment stage comprising, e.g., one air treatment chamber (e.g., cyclone) and a second downstream air treatment stage comprising a plurality of air treatment chambers (e.g., cyclones), in parallel.
- In addition, the hand vacuum cleaner has a handle.
- The forward portion may comprise any one or more of the operating components and the handle and the rearward portion may comprise the handle and any operating component which is not provided in the forward portion.
- The
access pivot 117 may be positioned at any location along theair treatment assembly 104 and themain body 102 of thesurface cleaning apparatus 100 to provide access to one or more components internal to thesurface cleaning apparatus 100. For example, as shown inFIGS. 2A, 29C, 49A, 56A, and 68A , theaccess pivot 117 may be located along themain body 102 between thepre-motor filter housing 160 and thebody portion 120, includingsuction motor housing 119. As shown, the user may rotate thebody portion 120 about theaccess pivot 117 to access thepre-motor filter 162 and/orpost-motor filter 172 such as, for example, for removal and replacement or cleaning. The user may similarly access thesuction motor 118,energy storage pack 300, and/oronboard power supply 304 such as, for example, for recharging, repair, replacement, or cleaning. In the examples shown inFIGS. 29C and 49A , theaccess pivot 117 is positioned rearward of thehandle 200. - It will be appreciated that the
handle 200 may be provided on either side of the pivot axis. For example, in the examples shown inFIGS. 2A, 56A, and 68A , theaccess pivot 117 is positioned forward of thehandle 200, such that thehandle 200 rotates with thebody portion 120 about theaccess pivot 117. However, it will be appreciated that handle 200 may be positioned rearward of the pivot axis. For example, as shown inFIGS. 29D, 49B, 51B, 56B, and 68B , theaccess pivot 117 may be located between theair treatment assembly 104 and themain body 102. In the examples shown, theaccess pivot 117 is forward of thehandle 200 and themain body 102 and rearward of theair treatment assembly 104. In the illustrated examples, theaccess pivot 117 is positioned between a forward end of thepre-motor filter housing 160 and therear end 130 of thecyclone chamber 124. As shown, the user may rotate themain body 102 and handle 200 about theaccess pivot 117 to access thepre-motor filter 162 such as for reasons described previously. - The
