- General Description of a Vacuum Cleaner that is Dockable with a Mobile Free Standing Air Treatment Unit
- Referring to
FIG. 1 , an exemplary embodiment of a surface cleaning apparatus is shown generally as 300. The following is a general discussion ofapparatus 300, 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 alternate embodiments disclosed herein. -
Surface cleaning apparatus 300 may be any surface cleaning apparatus which may be docked with a docking unit and optionally may be emptied by a docking unit. - Embodiments described herein include a cyclonic
air treatment member 316, and asurface cleaning apparatus 300 including the same.Surface cleaning apparatus 300 may be any type of surface cleaning apparatus, including for example a hand vacuum cleaner as shown, a stick vacuum cleaner, an upright vacuum cleaner, a canister vacuum cleaner, a robotic vacuum cleaner, an extractor, or a wet/dry type vacuum cleaner. - In
FIGS. 1-10 ,surface cleaning apparatus 300 is illustrated as a hand vacuum cleaner, which may also be referred to also as a “handvac” or “hand-held 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 vacuum may be held by the same one hand used to direct a dirty air inlet of the vacuum cleaner with respect to a surface to be cleaned. For example, handle 302 anddirty air inlet 304 may be rigidly coupled to each other (directly or indirectly), such as being integrally formed or separately molded and then non-removably secured together (e.g., adhesive or welding), 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. - Still referring to
FIGS. 1-10 ,surface cleaning apparatus 300 includes a main body or a handvac body having an air treatment member 316 (which may be permanently affixed to the main body or may be removable in part or in whole therefrom for emptying), adirty air inlet 304, aclean air outlet 308, and an air flow path extending between thedirty air inlet 304 and theclean air outlet 308. -
Surface cleaning apparatus 300 has afront end 322, arear end 324, an upper end (also referred to as the top) 326, and a lower end (also referred to as the bottom) 328, as exemplified inFIG. 1 . In the embodiment shown,dirty air inlet 304 is at a portion of apparatusfront end 322 andclean air outlet 308 is at a rearward portion ofapparatus 300 at apparatusrear end 324. It will be appreciated thatdirty air inlet 304 andclean air outlet 308 may be positioned in different locations ofapparatus 300. - A
suction motor 314 is provided to generate vacuum suction through air flow path, and may be positioned within a motor housing.Suction motor 314 may be a fan and motor assembly including an electric motor and impeller blade(s). In the illustrated embodiment,suction motor 314 is positioned in the air flow path downstream ofair treatment member 316. In this configuration,suction motor 314 may be referred to as a “clean air motor”. Alternatively,suction motor 314 may be positioned upstream ofair treatment member 316, and be referred to as a “dirty air motor”. -
Air treatment member 316 is configured to remove particles of dirt and other debris from the air flow. Anyair treatment member 316 that is emptyable by a docking unit may be used. - In the illustrated example,
air treatment member 316 includes a cyclone assembly (also referred to as a “cyclone bin assembly”) having a single cyclonic cleaning stage with asingle cyclone 318 and a dirt collection chamber 312 (also referred to as a “dirt collection region”, “dirt collection bin”, “dirt bin”, or “dirt chamber”).Cyclone 318 has a cyclone chamber.Dirt collection chamber 312 may be external to the cyclone chamber (i.e.,dirt collection chamber 312 may have a discrete volume from that of cyclone chamber) or it may be internal of the cyclone chamber as exemplified.Cyclone 318 anddirt collection chamber 312 may be of any configuration suitable for separating dirt from an air stream and collecting the separated dirt respectively, and may be in communication with dirt outlet(s) of the cyclone chamber. - In alternate embodiments,
air treatment member 316 may include a cyclone assembly having two or more cyclonic cleaning stages arranged in series with each other. Each cyclonic cleaning stage may include one or more cyclones arranged in parallel with each other and one or more dirt collection chambers, of any suitable configuration. The dirt collection chamber(s) may be external to the cyclone chambers of the cyclones. Each cyclone may have its own dirt collection chamber or two or more cyclones fluidically connected in parallel may have a single common dirt collection chamber. - In alternate embodiments,
air treatment member 316 need not be cyclonic and may comprise or consist of a non-cyclonic momentum separator, in which case theair treatment member 316 may have one or more air treatment chambers. - In the illustrated example,
surface cleaning apparatus 300 has anoutlet port 306, which when in an evacuation mode, may be connected in air flow communication withdirty air inlet 304. Aninlet port 310 is also provided onsurface cleaning apparatus 300, which when in an evacuation mode, may be in air flow communication with theclean air outlet 308. -
Surface cleaning apparatus 300 may include apre-motor filter 330 provided in the air flow path downstream ofair treatment member 316 and upstream ofsuction motor 314.Pre-motor filter 330 may be formed from any suitable physical, porous filter media. For example,pre-motor filter 330 may be one or more of a foam filter, felt filter, HEPA filter, or other physical filter media. In some embodiments,pre-motor filter 330 may include an electrostatic filter, or the like.Pre-motor filter 330 may be located in a pre-motor filter housing that is external to theair treatment member 316. -
Dirty air inlet 304 may be at thefront end 322 of thesurface cleaning apparatus 300. Optionally,front end 322 may be used as a nozzle to directly clean a surface. Alternatively, or in addition to functioning as a nozzle,front end 322 may be connected (e.g., directly connected) 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. As shown,dirty air inlet 304 may be positioned forward ofair treatment member 316, although this need not be the case. - Accordingly, in operation, after activating
suction motor 314, dirty air entersapparatus 300 throughdirty air inlet 304 and is directed to thecyclone 318. The dirty air flow may be directed to enter thecyclone 318 in a tangential direction so as to promote cyclonic dirt separation. Dirt particles and other debris may be disentrained (i.e., separated) from the dirty air flow as the dirty air flow travels throughcyclone 318. The disentrained dirt particles and debris may be discharged fromcyclone 318 through a cyclone dirt outlet intodirt collection chamber 312 that is external to the cyclone chamber, where the dirt particles and debris may be collected and stored untildirt collection chamber 312 is emptied. Alternately, as exemplified, the dirt particles and debris may be collected and stored in adirt collection chamber 312 that is internal of (part of) a cyclone chamber untildirt collection chamber 312 is emptied. -
Air exiting cyclone 318 may be directed to the optionalpre-motor filter 330. The air flow may pass throughpre-motor filter 330, and then exit intosuction motor 314 and then discharged fromapparatus 300 throughclean air outlet 308. Prior to exiting theclean air outlet 308, the treated air may pass through a post-motor filter, which may be one or more layers of filter media. - Power may be supplied to
suction motor 314 and other electrical components ofapparatus 300 from an onboard energy storage member, which may include, for example, one ormore batteries 332 or other energy storage device such as a capacitor. In the illustrated embodiment,apparatus 300 includes abattery pack 332.Battery pack 332 may be permanently connected toapparatus 300 and rechargeable in-situ, or removable fromapparatus 300. In the example shown,battery pack 332 is located withinhandle 304. Alternatively, or in addition tobattery pack 332, power may be supplied toapparatus 300 by an electrical cord (not shown) connected toapparatus 300 that can be electrically connected to mains power by at a standard wall electrical outlet. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, there is provided a mobile free standing
air treatment unit 100, which is operable as a vacuum cleaner and as a docking station. Accordingly, the mobile free standingair treatment unit 100 having anair treatment unit 208, avacuuming unit 200, and a first docking station (referred to herein as a first docking unit 400) for receiving asurface cleaning apparatus 100. When thesurface cleaning apparatus 300 is docked at thedocking unit 400, the mobile free standingair treatment unit 100 may be used to empty thesurface cleaning apparatus 300 and/or to clean a surface. To this end, the mobile free standingair treatment unit 100 may use one or more operating components of thesurface cleaning apparatus 300 to perform one or both of these operations, e.g., by using a suction motor and/or energy storage member of thesurface cleaning apparatus 300 - Accordingly, the mobile free standing
air treatment unit 100 may be operable in a first docking mode in which thesurface cleaning apparatus 300 is docked at thedocking unit 400 and is evacuated and/or a cleaning mode in which thesurface cleaning apparatus 300 is docked at thedocking unit 400 and the mobile free standingair treatment unit 100 is operable to clean a surface. An advantage of this aspect is that a dirt collection region in the mobile free standingair treatment unit 100 may be used both to receive dirt evacuated from thesurface cleaning apparatus 300 and dirt collected from use of theunit 100 in the cleaning mode. Accordingly, a user may only need to empty a single dirt collection region for multiple cleaning devices. Another advantage is that the suction motor and/or energy storage member of one device may be used in the operation of another device, e.g., a suction motor and/or energy storage member of thesurface cleaning apparatus 300 may be used to provide motive force and/or power to thevacuuming unit 200 in the cleaning mode. - In accordance with this aspect, referring to
FIG. 1 , shown therein is an exemplary embodiment of a mobile free standingair treatment unit 100. The mobile free standingair treatment unit 100 includes avacuuming unit 200 and adocking unit 400. The vacuumingunit 200 and adocking unit 400 may be a one piece assembly such that the docking unit is permanently mounted to, or integrally formed as part of, the vacuumingunit 200.FIG. 2 also depicts asurface cleaning apparatus 300 that is dockable with thedocking unit 400. - Vacuuming
unit 200 may be in the form of any type of surface cleaning apparatus. For example, it may have any type of dirty air inlet and any type of air treatment member or members. Further, it may be any type of surface cleaning apparatus as discussed herein such as a portable vacuum cleaner (e.g., a pod vacuum cleaner), a cannister vacuum cleaner, an upright vacuum cleaner, etc. - In
FIGS. 1-10 , vacuumingunit 200 is exemplified as a wet/dry vacuum cleaner, which may also be referred to as a “cannister” and may be optionally seated or removably mounted to a wheeled base of the like. As used herein, a wet/dry vacuum cleaner is a vacuum cleaner that can be operated in wet or dry conditions. The wet/dry vacuum cleaner may be moveable generally by thehandle 202 with a second hand typically required to direct air through an optionalflexible hose 206 into adirty air inlet 204. - Referring to
FIG. 1 , vacuumingunit 200 comprises anair treatment unit 208, adirty air inlet 204, aclean air outlet 228, and an air flow path extending between thedirty air inlet 204 and theclean air outlet 228. -
Air treatment member 208 is configured to remove particles of dirt and other debris from the air flow.Air treatment member 208 may be any type of air treatment member or members as described with respect toair treatment member 316. - As exemplified in
FIG. 5 ,air treatment member 208 comprises acyclone assembly 236 having a singlecyclonic cleaning stage 230 with asingle cyclone 236 and adirt collection chamber 214 that is internal of thecyclone 236. - In some embodiments, the
air treatment unit 208 may include a plurality of air treatment stages. As exemplified inFIGS. 5 and 6 , theair treatment unit 208 may include a first stageair treatment member 236 and a downstreamsecond stage 232 having a second stageair treatment member 234. As shown, the first stageair treatment member 236 may include the firstdirt collection region 214 positioned at a lower end. In some embodiments, there may be a plurality of dirt collection chambers. - It will be appreciated that the first stage air treatment member and the second stage
air treatment member 234 may use any air treatment elements known in the air/dirt separation arts for treating an inflow of dirty air and otherwise separating the air flow from air-entrained dirt and may have one or more air treatment elements. For example, the first and/or second stageair treatment member 234 may be a filter media, a cyclone, a momentum separator, a bag or some combination thereof. As exemplified inFIG. 6 , the first stageair treatment member 236 is a cyclone and the second stageair treatment member 234 is a filter media. In some embodiments, the firstdirt collection region 214 may include afirst stage cyclone 236 and a second stageair treatment member 234 may include a second cyclone. - The dirty air flow may be directed to enter the
cyclone 236 in a tangential direction so as to promote cyclonic action. Dirt particles and other debris may be disentrained (i.e., separated) from the dirty air flow as the dirty air flow travels throughcyclone 236. The disentrained dirt particles and debris may discharge fromcyclone 236 intodirt collection chamber 214, where the dirt particles and debris may be collected and stored untildirt collection chamber 214 is emptied. -
Air exiting cyclone 236 may be directed to enter thesecond stage 232, for example, a second cyclone. The air flow may separate the dirt particles and other debris as the air travels through thesecond stage 232. The separated dirt particles may discharge from the second cyclone into dirt collection chamber orregion 214. In alternate embodiments, the separated dirt particles may discharge from the second cyclone into a second dirt collection chamber. - In some embodiments, first
dirt collection region 214 and second stageair treatment member 234 may each include a cyclone assembly having two or more cyclonic cleaning stages arranged in series with each other. Each cyclonic cleaning stage may include one or more cyclones arranged in parallel with each other and one or more dirt collection chambers, of any suitable configuration. The dirt collection chamber(s) may be external to the cyclone chambers of the cyclones. Each cyclone may have its own dirt collection chamber or two or more cyclones fluidically connected in parallel may have a single common dirt collection chamber. - In some embodiments,
air exiting cyclone 236 may be directed into a filter located within the second stageair treatment member 234. Alternately, or in addition, the air exiting the second cyclone may be directed into a filter. The air may pass through the filter and then exit thevacuuming unit 200 throughclean air outlet 228. Prior to exiting theclean air outlet 308, the treated air may pass through a post-motor filter, which may be one or more layers of filter media. - In order to enable the
air treatment unit 208 to operate to evacuate dirt from a docked vacuum cleaner, the air treatment unit is connectable in air flow communication with a dirt collection region of the docked vacuum cleaner. Accordingly,air treatment unit 208 may include a seconddirty air inlet 226. If thesuction motor 314 of the dockedvacuum cleaner 300 is used during an evacuation operation to provide some or all of the air flow, then theair treatment unit 208 is also connectable in air flow communication with the docked vacuum cleaner at a location upstream of thesuction motor 314 and an air flow path may therefore extend from seconddirty air inlet 226 to cleanair outlet 228. As exemplified inFIGS. 1-2 , the seconddirty air inlet 226 may form afirst inlet 402 and theclean air outlet 228 may form afirst outlet 404 of thedocking unit 400. - As exemplified in
FIG. 2 , thedocking unit 400 is configured to engage thesurface cleaning apparatus 300 such that theoutlet port 306 of thesurface cleaning apparatus 300 is connected in flow communication withfirst inlet 402 of thedocking unit 400 andinlet port 310 is connected in flow communication withfirst outlet 404 of thedocking unit 400. - The
outlet port 306 ofsurface cleaning apparatus 300 may be at any location known in the art and, as exemplified, it may be in a wall of thedirt collection chamber 312. Theinlet port 310 ofsurface cleaning apparatus 300 may be at any location known in the art and, as exemplified, it may be upstream ofsuction motor 314 of thesurface cleaning apparatus 300 wherein the location is isolated from thecyclone 318. - The mobile free standing
air treatment unit 100 may operate with multiple air flow paths. For example, it may be operable to empty a dockedsurface cleaning apparatus 300 and it may be operable as a surface cleaning apparatus. In such an embodiment, in a first docking mode, the mobile free standingair treatment unit 100 may have a firstair flow path 1000 to withdraw dirt from a dockedsurface cleaning apparatus 300 and, in a cleaning mode, it may have anair flow path 2000 to draw dirt from a surface to be cleaned. - As exemplified in
FIGS. 2, 5 and 9 , the firstair flow path 1000 may extend from thefirst inlet 402 to thefirst outlet 404, with theair treatment unit 208 in provided in the firstair flow path 1000. As exemplified inFIGS. 3 and 6 , the secondair flow path 2000 may extend from thedirty air inlet 204 to thefirst outlet 404, with theair treatment unit 208 is provided in the secondair flow path 2000. Accordingly, air may enter thevacuuming unit 200 through either thedirt air inlet 226 or thedirty air inlet 204. - In the first docking mode (shown in
FIGS. 2, 5 and 9 ) thesurface cleaning apparatus 300 may be docked at thedocking system 400 and connected in air flow communication with thefirst inlet 402. When in the first docking mode, the mobile free standingair treatment unit 100 is operable using the firstair flow path 1000 to withdraw dirt from thesurface cleaning apparatus 300 and collect the withdrawn dirt in theair treatment unit 208. In other words, the firstair flow path 1000 may be used to evacuate dirt from thedirt collection region 312 of thesurface cleaning apparatus 300 into thedirt collection region 214 in theair treatment unit 208. - Optionally, as exemplified, the
suction motor 314 of thesurface cleaning apparatus 300 is used to draw air through the firstair flow path 1000. It will be appreciated that, in other embodiments, a different suction motor may be used, e.g., the suction motor may be part of the mobile free standingair treatment unit 100. - In the cleaning mode (shown in
FIGS. 3 and 6 ) thesurface cleaning apparatus 300 is docked at thedocking system 400 and thefirst outlet 404 is connected in air flow communication with theinlet port 310 of thesurface cleaning apparatus 300. The mobile free standingair treatment unit 100 is operable using the secondair flow path 2000 to clean a surface. In other words, the secondair flow path 2000 may be used to collect dirt through theinlet 206 such that the mobile free standingair treatment unit 100 may be used to clean the surface. - Optionally, as exemplified, the
suction motor 314 of thesurface cleaning apparatus 300 is used to draw air through the firstair flow path 2000. It will be appreciated that, in other embodiments, a different suction motor may be used, e.g., the suction motor may be part of the mobile free standingair treatment unit 100. - By providing two different air flow paths for two different modes of operation, the dirt from the vacuuming
unit 200 and thesurface cleaning apparatus 300 in theair treatment unit 208 may both be collected in thedirt collection region 214. For example, thesurface cleaning apparatus 300 may be docked at thedocking system 400 and may use the firstair flow path 100 to remove collected dirt from thesurface cleaning apparatus 300 into thedirt collection region 214. The user may then proceed to use thesurface cleaning apparatus 300 for further cleanup of a surface and/or may empty the dirt collected by multiple surface cleaning apparatus from a single location. - It will be appreciated that the
docking unit 400 may be any design capable of facilitating the formation of the firstair flow path 1000 and/or the secondair flow path 2000 between thesurface cleaning apparatus 300 and thevacuum unit 200. For example, thedocking unit 400 may be adjacent to, or integrally formed with, the vacuum unit 200 (e.g.,FIGS. 1-3 ), or may be an independent docking unit 400 (e.g.,FIGS. 4-7 ). - As exemplified in
FIGS. 1-3 , thedocking unit 400 is attached directly toair treatment member 208. Thedocking unit 400 may use any method to align asurface cleaning apparatus 300 within thedocking unit 400 such that theair flow path 1000 and/or 2000 can be formed. For example,system 400 includes twocoupling members 430 forsurface cleaning apparatus 300 to contact. As exemplified inFIG. 2 , thecoupling members 430 are sleeves that are attached to theair treatment unit 208 for receiving thesurface cleaning apparatus 300. In some embodiments, thesystem 400 may include a single sleeve for thesurface cleaning apparatus 300 to contact. Other examples of coupling thesurface cleaning apparatus 300 to theunit 208 may include a clip, a slot within theair treatment unit 208, magnets, and/or any other coupling member for connecting thesurface cleaning apparatus 300 todocking system 400. - As exemplified in
FIGS. 2-3 , when thesurface cleaning apparatus 300 is docked at thedocking system 400 ready for evacuation, thefirst inlet 402 is connected in flow communication with theoutlet port 306 of thesurface cleaning apparatus 300 andclean air outlet 404 is connected in flow communication with theinlet port 310 ofsurface cleaning apparatus 300. In other words, when thesurface cleaning apparatus 300 is positioned in thedocking system 400, theoutlet port 306 is aligned with theinlet port 402 and theinlet port 310 is aligned with theoutlet port 404, thereby facilitating theair flow path 1000. - Accordingly, when in the first docking mode with the docking unit of
FIGS. 1-3 , as illustrated inFIG. 2 , the firstair flow path 1000 may travel fromdirt collection chamber 312 ofsurface cleaning apparatus 300, outoutlet port 306 and throughfirst inlet 402 of thedocking unit 400.Air flow path 1000 may then travel throughdocking unit 400 todirty air outlet 408 and through seconddirty air inlet 226 ofair treatment unit 208 into theair treatment unit 208. From there,air flow path 1000 may travel throughclean air outlet 228 ofair treatment unit 208 to cleanair inlet 410 ofdocking unit 400.Air flow path 1000 may then continue throughclean air outlet 404 ofdocking unit 400,inlet port 310 ofsurface cleaning apparatus 300,suction motor 314 and outclean air outlet 308. - As exemplified in
FIGS. 4-7 , thedocking unit 400 is an independent region that provides an intermediary coupling region between thesurface cleaning apparatus 300 and thevacuuming unit 200. In some embodiments, as exemplified inFIG. 4 , thedocking unit 400 includes a location, e.g.,base 406, for receiving theair treatment unit 208 and vacuumingunit 200, and alocation 420 for thesurface cleaning apparatus 300 to be docked.Docking unit 400 may use any method to align thevacuuming unit 200 andair treatment unit 208 within thestation 400.Docking unit 400 may further include any method to align surface cleaning apparatus within thestation 400. - Referring to
FIG. 4 , as exemplified, thedocking unit 400 comprises abody 401 having abase 406. As shown, thedocking unit 400 is generally configured as a vertical, rectangular structure, having an upright section. It will be appreciated that thedocking unit 400 may have any other suitable shape or design. - When in the first docking mode with the docking unit of
FIGS. 4-9 , as illustrated inFIG. 5 , thedocking unit 400 may include afirst docking outlet 408 and asecond inlet 410.First docking outlet 408 may be connected in fluid communication with the seconddirty air inlet 226 ofair treatment unit 208 and thesecond inlet 410 may be connected in fluid communication with theclean air outlet 228 ofair treatment unit 208. As illustrated inFIG. 5 , theair flow path 1000 is the similar to theair flow path 1000 shown inFIG. 2 , but the air passes through the body of thedocking unit 400, frominlet 402 tooutlet 408, and then throughinlet 226 and fromoutlet 228 throughinlet 410 and then throughoutlet 410. - Referring to
FIGS. 3 and 6 , as exemplified, theunit 100 is in a cleaning mode. As illustrated inFIG. 3 , the secondair flow path 2000 extends from thedirty air inlet 204 of vacuumingunit 200 throughair treatment member 208 tooutlet 404.Outlet 404 is in fluid communication withinlet port 310 ofsurface cleaning apparatus 300. The secondair flow path 2000 may extend, as illustrated, from theinlet port 310 through thesuction motor 314 ofsurface cleaning apparatus 310 and out theclean air outlet 308. As illustrated inFIG. 6 , the secondair flow path 2000 is similar to theair flow path 2000 illustrated inFIG. 3 , except that the air also passes through the body of thedocking unit 400, from thedirty air inlet 204 of vacuumingunit 200 throughair treatment member 208 to cleanair outlet 228 and throughclean air inlet 410 ofdocking unit 400.Air flow path 2000 may then continue throughclean air outlet 404 ofdocking unit 400,inlet port 310 ofsurface cleaning apparatus 300,suction motor 314 and outclean air outlet 308. - In some embodiments, the vacuuming
unit 200 may include aflexible hose 206 and/or other accessory positioned upstream of thesecond inlet 204. When thesurface cleaning apparatus 300 is docked and operating in the cleaning mode, theflexible hose 206 may be used to clean areas proximate the mobile free standingair treatment unit 100. As exemplified inFIGS. 1-3, 5, 6, and 8-10 , theflexible hose 206 may protrude from theair treatment unit 208 and may be in fluid communication withsecond inlet 204. It will be appreciated that theflexible hose 206 may be located anywhere on theair treatment unit 208. - During operation in the cleaning mode, as exemplified in
FIGS. 3 and 6 and illustrated by the secondair flow path 2000, air may travel from theflexible hose 206, through thesecond inlet 204 and into theair treatment member 208 where the dirt is collected within thedirt collection chamber 214. - The
flexible hose 206 may be any length and/or size. Theflexible hose 206 may be connected (e.g., directly connected) 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, or any other cleaning apparatus. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, the
air treatment unit 208 may be removably mounted to the mobile free standingair treatment unit 100, such as for emptying or cleaning. -
Air treatment unit 208 may be removable from the mobile free standingair treatment unit 100 for emptying, either with thedirt collection chamber 214 thereof closed or with thedirt collection chamber 214 open (e.g., a lid 244 may be removed). Accordingly, theair treatment unit 208 may be removably mounted to a main body. The main body may comprise, consist essentially of or consist of thedocking unit 400. Accordingly, thebody 401 of thedocking unit 400 may be the main body of thevacuuming unit 200 or the mobile free standingair treatment unit 100 may have a main body to which thedocking unit 400 and thevacuuming unit 200 may be mounted and theair treatment unit 208 may be removable therefrom. - In order to empty the
air treatment unit 208 theair treatment unit 208 may have anopenable door 216. Thedoor 216 may be positioned anywhere on theair treatment unit 208. When thedoor 216 is opened, dirt may be emptyable from theair treatment unit 208. Theair treatment unit 208 may be removable from the mobile free standingair treatment unit 100 with thedoor 216 closed. Accordingly, a user may remove theair treatment unit 208 from theunit 100 with thedoor 216 closed, such that dirt does not accidentally spill. The user may then move theair treatment unit 208 and empty thedirt collection region 214. - Optionally, the
door 216 may be revealed when theair treatment unit 208 is removed. For example,door 216 may be part or all of a lower wall of theair treatment unit 208. - The
door 216 may open by any means. As exemplified inFIG. 4 , theopenable door 216 may have ahandle 218 and may be pivotably openable in an outward direction fromair treatment member 208 around ahinge 220. In some embodiments, thedoor 216 may open by, including, but not limited to, sliding, opening inwardly, and/or may be fully removably from theair treatment unit 208. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, a common motor and fan assembly may be used to operate the
surface cleaning apparatus 300 when used to clean a surface and the mobile free standingair treatment unit 100 when thesurface cleaning apparatus 300 is docked. - Accordingly, the mobile free standing
air treatment unit 100 may operate usingsuction motor 314 located within thesurface cleaning apparatus 300. As such, each of the docking mode and cleaning mode may be operable using, for example,suction motor 314 of thesurface cleaning apparatus 300. Accordingly, in some embodiments, vacuumingunit 200 may not include a fan and motor assembly. Using asingle suction motor 314 may reduce the initial cost since an independent suction motor is not required to operate theunit 100. Additionally, providing an absence of suction motor in thevacuuming unit 200 may simplify the design, decrease weight, and make manufacturing more efficient. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, a common power source may be used to operate the
surface cleaning apparatus 300 when used to clean a surface and the mobile free standingair treatment unit 100 when thesurface cleaning apparatus 300 is docked. - Accordingly, the mobile free standing
air treatment unit 100 may operate using a single energy storage member, and optionally suctionmotor 314, located within thesurface cleaning apparatus 300. As such, each of the docking mode and cleaning mode may be operable using, for example,battery 332, optionally withsuction motor 314, of thesurface cleaning apparatus 300. Accordingly, in some embodiments, vacuumingunit 200 may not include an on board energy storage member and it may optionally not include a power cord. Using a single energy storage member may reduce the initial cost since an independent battery is not required to operate theunit 100. Additionally, providing an absence of energy storage member in thevacuuming unit 200 may simplify the design, decrease weight, and make manufacturing more efficient. - When in the first docking mode, the sole air moving member of the
unit 100 may be thesuction motor 314 ofsurface cleaning apparatus 300. As exemplified inFIGS. 2, 3, 5, 6, and 9 , the mobile free standingair treatment unit 100 may be operable throughfirst flow path 1000 and secondair flow path 2000 through the sole air movement provided by thesuction motor 314 and fan assembly ofsurface cleaning apparatus 300. In other words, when thesurface cleaning apparatus 300 is docked at thefirst docking unit 400, thesuction motor 312 of thesurface cleaning apparatus 300 may be the sole air moving member of a combiner mobile free standingair treatment unit 100 andsurface cleaning apparatus 300. - While the
unit 100 and thesurface cleaning apparatus 300 may usesuction motor 314 of thesurface cleaning apparatus 300 as a common suction source as discussed previously, as exemplified inFIG. 4 , asuction motor 212 may be provided in thevacuuming unit 200 to generate vacuum suction through an air flow path, and may be positioned within a motor housing.Suction motor 212 may be a fan-motor assembly including an electric motor and impeller blade(s). In embodiments where thevacuuming unit 200 includes asuction motor 212, it will be appreciated that either or both of thesuction motor air flow path 1000 and/or the secondair flow path 2000. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, the
unit 100 may include a charging station to recharge an on board energy storage member. For example, theunit 100 may include an energy storage member and may be operable in a portable mode when not connected to a mains power supply. Alternately, or in addition,surface cleaning apparatus 300 may include an energy storage member. In any such case, theunit 100 may be connected to a mains power supply by a power cord and may therefore recharge an energy storage member provided inunit 100 and/orsurface cleaning apparatus 300. - For example,
docking unit 400 may include acharging unit 414 where theenergy storage member 332 of thesurface cleaning apparatus 300 is rechargeable when docked at thedocking system 400. Accordingly, thesurface cleaning apparatus 300 may be charged by thesame docking unit 400 whilesurface cleaning apparatus 300 is emptied, thereby providing a single device used for multiple operations. Thesurface cleaning apparatus 300 may evacuate dirt from thedirt collection chamber 312 at the same time thatenergy storage member 332 is charged at chargingunit 414. - As exemplified in
FIG. 5 ,docking unit 400 may include acharging unit 414 that may be powered by electrical connection (power cord) 412. As shown,electrical connection 412 may be a connection to a mains power supply, such as, for example, an outlet to be plugged into a wall. In some embodiments, the power supply of thedocking unit 400 used to recharge thesurface cleaning apparatus 300 may be an on board energy storage member located withindocking unit 400. - In some embodiments,
unit 100 may be designed such that theunit 100 may be carried by the user with thehandle 202 of thevacuuming unit 200. Accordingly, the user may clean up areas with larger spills with vacuumingunit 200 and clean smaller, harder to reach areas with thesurface cleaning apparatus 300. In other words, thesuction motor 314 and/orbattery 332 of thesurface cleaning apparatus 300 may be used to provide suction and/or electrical power to thevacuuming unit 200 to clean surfaces using the secondair flow path 2000 and/or thesurface cleaning apparatus 300 may be separated from the vacuumingunit 200 to clean harder to reach areas. - In accordance with this aspect, which may be used by itself or in combination with one or more other aspects, the mobile free standing
air treatment unit 100 is provided a second docking unit for a second surface cleaning apparatus. The second docking unit includes a third dirty air inlet and a third air flow path extending from the third dirty air inlet to the first clean air outlet.
