FIG. 1 illustrates a floor cleaner 10 with abase 12 movable over a surface to be cleaned, abody portion 14 pivotally mounted to thebase 12, and afluid dispensing member 20 removably mounted to thebody portion 14. In the illustrated embodiment, the fluid dispensing member is ahandle assembly 20. Thehandle assembly 20 is configured to include a dispensingnozzle 24. During operation of the floor cleaner 10, it may be useful to remove thefluid dispensing member 20 from thebody portion 14, for example, for spot treatment cleaning. The use of thehandle assembly 20 as a dispensing member enables a solution to be applied to the surface to be cleaned with a degree of accuracy as to the position and region of application. When thehandle assembly 20 is removed from thebody portion 14, the user is able to apply a spot treatment to a targeted area of the surface to be cleaned remote from the floor cleaner 10 via the dispensingnozzle 24. - In the illustrated embodiment, the
handle assembly 20 and thebody portion 14 are pivotal relative to thebase 12 between an upright storage position (FIG. 1 ) and an inclined floor cleaning position. The floor cleaner 10 includes one or more tanks for storing liquid and is configured to distribute cleaning solution to the floor. In the illustrated embodiment, the floor cleaner 10 includes asupply tank 16 for providing water or other cleaning solution, optionally, adetergent tank 17, aspot treatment tank 28, and arecovery tank 18 for collecting dirty liquid extracted from the surface being cleaned. Thespot treatment tank 28, further discussed below, allows the user to apply spot treatment solution to a localized portion of a surface to be cleaned. Thesupply tank 16 anddetergent tank 17 may be positioned on thebody portion 14, thefluid dispensing member 20, or operatively coupled to thebase 12. - Referring to
FIG. 10 , thebase 12 has a fluid distribution system including afluid distributer 56 in fluid communication with thesupply tank 16 and thedetergent tank 17. Thefluid distributer 56 distributes solution from thesupply tank 16 and/or thedetergent tank 17 to the surface to be cleaned. The base 12 may include one or more brushrolls 54 to agitate and scrub the cleaning solution on the surface to dislodge embedded dirt or debris. In one embodiment, the floor cleaner 10 includes a first fluid distribution system and a second fluid distribution system. In this embodiment, the first fluid distribution system includes thefluid distributer 56 on the base 12 in fluid communication with thesupply tank 16. The second fluid distribution system includes thefluid dispensing member 20, and is operable independent of the first fluid distribution system. The second fluid distribution system also includes agrip portion 22, a second fluid supply tank orspot treatment tank 28, the dispensingnozzle 24, apump 30 connecting thesecond supply tank 28 to the dispensingnozzle 24, a power source, and anactuator 26 electrically connected to the power source and pump 30. - Referring again to
FIG. 10 , optionally the applied cleaning solution is extracted from the surface by a fluid recovery system. In one embodiment, the fluid recovery system includes a mop pad or other absorbent media disposed on thebase 12 of the floor cleaner. In one embodiment, the fluid recovery system includes asuction nozzle 58, arecovery tank 18, and asuction source 50. In the illustrated embodiment, thesuction nozzle 58 has asuction inlet 52 at least partially spanning the front portion of thebase 12. Thesuction nozzle 58 is in fluid flow communication with therecovery tank 18 by way of anair duct 60 operatively coupled between the base 12 and thebody portion 14 . Thesuction source 50, housed in thebody portion 14 draws air and liquid through thesuction nozzle 52 and theair duct 60 of thebase 12, through an air/liquid separator in therecovery tank 18, to then exhaust the air to the atmosphere leaving separated liquid in therecovery tank 18. In other embodiments, thesuction source 50 may be housed in a different portion of the floor cleaner 10, such as thebase 12. During operation, the floor cleaner 10 distributes cleaning solution to the surface, while simultaneously or sequentially extracting and recovering the applied cleaning solution in a continuous operation. - In the illustrated embodiment, the
recovery tank 18 is removably coupled to thebody portion 14 to allow a user to remove therecovery tank 18 and empty the liquid contents. In other embodiments, therecovery tank 18 may be operatively coupled to another portion of the floor cleaner 10, such as thebase 12. In one embodiment, the floor cleaner 10 is not an extractor and does not include a suction source and recovery tank. In one embodiment without a suction source and recovery tank, the base includes a mop pad or other absorbent media for fluid recovery. - The
handle assembly 20 includes thegrip portion 22, the dispensingnozzle 24 in fluid communication with thespot treatment tank 28 or other supply tank or reservoir, and theactuator 26 configured to be activated by a user to dispense solution through the dispensingnozzle 24. Thehandle assembly 20 may be used as a fluid dispensing member independent of the fluid distribution system in thebase 12 of the floor cleaner, as well as independent of the fluid recovery system of the floor cleaner. In one embodiment, thehandle assembly 20 may be used as a fluid dispensing member remote from the fluid distribution system and the fluid recovery system of the floor cleaner. The fluid dispensing member may be used independently from the fluid recovery system, which means that the fluid dispensing member can be moved independently from thesuction nozzle 52 or any other suction nozzle or other fluid recovery system on the floor cleaner 10 (such as one used with an accessory hose for above-floor cleaning). In contrast to known fluid dispensers associated with, affixed in proximity to, or attached to a suction nozzle of fluid recovery system for the purpose of depositing fluid onto a surface to be cleaned near the suction nozzle for convenient recovery, thehandle assembly 20 is not associated with, affixed in proximity to, or attached to any suction nozzle of the floor cleaner 10 allowing the cleaning fluid to be deposited on the cleaning surface without immediate recovery thereby allowing the deposited cleaning fluid sufficient time treat stains on the surface. - The
handle assembly 20 may include awand 23 extending from thegrip portion 22. In one embodiment, thegrip portion 22 is in an upper portion of thehandle assembly 20 and the dispensingnozzle 24 is positioned in a lower portion. The dispensingnozzle 24 may be positioned in the wand to dispense fluid through thewand 23 when the user activates theactuator 26. - The fluid dispensing member, here illustrated as the
handle assembly 20, is selectively removable from the body portion. Thehandle assembly 20 includes a first position in which thehandle assembly 20 is mounted to and movable with thebody portion 14, and a second position in which thehandle assembly 20 is released from and movable independently of thebody portion 14. In one embodiment, thehandle assembly 20 is configured to steer the floor cleaner 10 along the surface to be cleaned in the first position, or mounted position. When thehandle assembly 20 is in the second position, removed from thebody portion 14, the user is able to apply a spot treatment to a targeted area of the surface to be cleaned via the dispensingnozzle 24. - The
handle assembly 20 is received in an aperture orinterior 42 of the body portion and removed from the interior 42 by pulling thehandle assembly 20 out of the interior 42. In the illustrated embodiment, theaperture 42 forms alongitudinal axis 46 and thewand 23 slides into and out of theaperture 42 along thelongitudinal axis 46. In one embodiment, the interior 42 may be a recess or pocket on thebody portion 14 configured to receive a portion of thehandle assembly 20. Thehandle assembly 20 is releasably attached to thebody portion 14 using alatch 38 having arelease button 40. In the illustrated embodiment, thebody portion 14 includes thelatch 38. In one embodiment, thehandle assembly 20 includes thelatch 38. Thelatch 38 includes a first retaining feature (not shown) that engages with a corresponding second retaining feature, such as a recess 41 (FIGS. 2 and2a ) on thehandle assembly 20. The latch first retaining feature may be a hook, catch, protrusion, rib, recess, aperture, or other retaining feature as desired. Thehandle retaining feature 41 may be a hook, catch, protrusion, rib, recess, aperture, or other retaining feature corresponding to and engageable with the latch first retaining feature as desired to releaseably couple thehandle assembly 20 to thebody portion 14. The user removes thehandle assembly 20 from the cleaner 10 by pressing therelease button 40 releasing thelatch 38, and pulling thehandle assembly 20 away from thebody portion 14. - In the embodiment shown in
FIGS. 5-7 , theremovable handle 20 includes thegrip 22, the dispensingnozzle 24, theactuator 26, and thespot treatment tank 28. Thespot treatment tank 28 is in fluid communication with the dispensingnozzle 24 of thehandle assembly 20 via asupply tube 44. As shown inFIG. 6 , thehandle assembly 20 contains apump 30 and abattery 37. Upon the user engaging theactuator 26, theactuator 26 activates aswitch 32, such as a microswitch, that activates thepump 30. Thepump 30 draws solution from thespot treatment tank 28 through a dip tube 43 (FIG. 7 ), then moves liquid through thesupply tube 44, through acheck valve 36 and out the dispensingnozzle 24. This arrangement allows the user to operate theremovable handle 20 in an untethered and remote position, independent of thebody portion 14 of the floor cleaner. - Further shown in the embodiment of
FIGS. 6 and7 , thespot treatment tank 28 is operatively and removably coupled to thehandle assembly 20 by aspot treatment housing 35. Thespot treatment tank 28 is received into thespot treatment housing 35, and secured to thehousing 35 by alatch 34. A latching feature, such as arecess 39 on thespot treatment tank 28 receives thelatch 34 to secure thetank 28. Thelatch 34 secures thespot treatment tank 28 to thehousing 35 and handleassembly 20. Thespot treatment tank 28 is removable from thehandle assembly 20 by releasing thelatch 34 and pulling thetank 28 away from thehousing 35. Thespot treatment tank 28 may be a refillable container or may be a disposable container containing a single use amount of solution. - In one embodiment, the
spot treatment tank 28 may be operatively and removably coupled to thebody portion 14 of the floor cleaner 10 instead of being coupled to thefluid dispensing member 20. In this embodiment, thefluid dispensing member 20 is tethered to thebody portion 14 by a tube fluidly connected to thespot treatment tank 28 configured to dispense solution from thefluid dispensing member 20 in the second position. In this embodiment, the pump may be on thefluid dispensing member 20 and powered by a battery to draw fluid from the spot treatment tank on the body portion through the tube to the dispensingnozzle 24. In one embodiment, the fluid dispensing member is tethered to the body portion by an electrical connection, wherein the pump on the fluid dispensing member is powered through the electrical connection in the tether. In an alternate embodiment, the pump and the spot treatment tank may both be on thebody portion 14 and fluidly connected to the dispensingnozzle 24 on thefluid dispensing member 20. - In the embodiment shown in
FIG. 2a , instead of a spot treatment tank, thefluid dispensing member 20 is fluidly connected to thesupply tank 16 and/or thedetergent tank 17 tethered by atube 45 to provide cleaning solution to thefluid dispensing member 20 in the second position. In this embodiment, the pump may be in thefluid dispensing member 20 and powered by a battery or powered by an electrical connection from thebody portion 14, or the pump may be on thebody portion 14 of the floor cleaner 10. In one embodiment, thesupply tank 16 and/ordetergent tank 17 are removable from thebody portion 14 while fluidly connected to thefluid dispensing member 20 to enable the user to apply spot treatment remote from the floor cleaner 10. - The
pump 30 may be manually operated or electrically operated. In the illustrated embodiment, thepump 30 is powered bybattery 37. Thepump 30 is activated by theactuator 26. Theactuator 26 may be a button, trigger, switch, or similar actuation mechanism. In operation, the user presses theactuator 26 to energize the pump for an electrical pump, or presses the actuator to drive a mechanical pump, to move cleaning solution from thespot treatment tank 28 through the dispensingnozzle 24 located on thefluid dispensing member 20. This allows the user to selectively apply solution to the surface to be cleaned, for example, to a particularly dirty spot on the surface to be cleaned. - In one embodiment, upon the user's actuation of the
actuator 26, cleaning solution flows by gravity from thespot treatment tank 28, through thesupply tube 44, to the dispensingnozzle 24. In this embodiment, theactuator 26 is communicatively coupled with a valve to be opened if theactuator 26 is actuated and closed if theactuator 26 is released. The user can selectively actuate theactuator 26 to open the valve to allow passage of the cleaning solution to the dispensingnozzle 24. - In use of the floor cleaner 10, it will be appreciated that it is convenient for the user, if wishing to subject the surface to be cleaned to pre or post-cleaning spot treatment, either localized or over a larger area, to dismount the
fluid dispensing member 20 from thebody portion 14 and wield it remote from the floor cleaner 10 as required to apply the liquid where needed. After use, the fluid dispensing member20 can be returned to its mounted position on thebody portion 14. - In one embodiment illustrated in
FIGS. 8 and 8a , theactuator 26 on thehandle assembly 20 is accessible when thehandle 20 is removed from thebody portion 14 in the second position, and retracted into thegrip portion 22 when thehandle 20 is installed on thebody portion 14 in the first position. As shown inFIG. 9 and9a , theactuator 26 and switch 32 are attached to acarriage assembly 72 that is pivotally mounted in the grip portion and movable between a carriage first position and a carriage second position. When thecarriage assembly 72 is in the carriage second position, theactuator 26 is extended through anaperture 78 in the grip, operable as an actuator in a position accessible to the user. When thecarriage assembly 72 is in the first position, theactuator 26 is retracted into theaperture 78 in the grip and not operable as an actuator, being not accessible to the user. Apush rod 74 is positioned in thewand 23 and configured to axially move within thewand 23 to press thecarriage assembly 72 from the carriage second position to the carriage first position. Thepush rod 74 is configured to engage with thebody portion 14 when installed on the body portion such that thepush rod 74 is displaced upwardly toward thegrip portion 22, moving thecarriage assembly 72. Aspring 76 is provided in the grip to press thecarriage assembly 72 toward the carriage second position. Thepush rod 74 presses thecarriage assembly 72 against the force of thespring 76 into the carriage first position. When thehandle assembly 20 is removed from thebody portion 14 releasing thepush rod 74, the force of thecompressed spring 76 presses theassembly 72 andactuator 26 to rotate about apivot 80, and moves theactuator 26 through theaperture 78 of thegrip 22, and holds the actuator in a position that is accessible to the user. Recessing thespot cleaning actuator 26 when thehandle assembly 20 is installed on thebody portion 14 reduces confusion of the user about solution distribution when the floor cleaner 10 is used in the inclined use position. - As schematically illustrated in
FIGS. 11 and 12 , thehandle assembly 20 includes anelectrical circuit 70 connecting the user-activatedswitch 32 controlled by theactuator 26, thebattery 37, and thepump 30. Theswitch 32 is open when theactuator 26 is not actuated, and closed when theactuator 26 is actuated. Additionally, thehandle assembly 20 and theelectrical circuit 70 may be configured to include a lock-out that prevents the dispensingnozzle 24 from distributing solution when thehandle assembly 20 is installed on the body portion in the first position. In one embodiment, the lock-out includes asecond switch 33 that is closed when thehandle assembly 20 is removed from the body portion in the second position, and is open when thehandle assembly 20 is installed on the body portion in the first position. When both switches 32, 33 are closed, the circuit is activated and capable of distributing solution from the dispensingnozzle 24. When either of theswitches - As schematically illustrated in
FIGS. 14 and15 , in one embodiment, thehandle assembly 20 includes abutton 62 positioned adjacent thesecond switch 33 and pressed by aspring 66 away from thesecond switch 33. Thebutton 62 is positioned on thehandle assembly 20 and configured such that thebutton 62 is pressed against the force of thespring 66 when thehandle assembly 20 is attached to thebody portion 14 to activate thesecond switch 33. In this embodiment, thesecond switch 33 is wired in parallel to the pump (FIG. 11 ). When thehandle assembly 20 is removed from thebody portion 14, thespring 66 presses thebutton 62 away from thesecond switch 33 to enable thepump 30 and extend thebutton 62 outside of the handle assembly 20 (FIG. 14 ). When thehandle assembly 20 is reinserted into the interior 42 of the body portion, thebutton 62 is pressed by thebody portion 14 to activate thesecond switch 33 and disable thepump 30. In another embodiment, thesecond switch 33 is in series with the pump 30 (Fig. 12 ), and thebutton 62 is configured with a mechanism to open thesecond switch 33 to disable thepump 30. - In operation, a user operating the floor cleaner 10 can steer the
base 12 of the floor cleaner 10 along the surface to be cleaned using thehandle assembly 20 in the first position. In one embodiment, the user steers thebase 12 of the floor cleaner using thegrip portion 22 of thehandle assembly 20. In another embodiment, the user steers thebase 12 of the floor cleaner independent of interaction with thegrip portion 22 of thefluid dispensing member 20. A user can apply a spot treatment to the surface to be cleaned when thehandle assembly 20 is in the second position. To move thehandle assembly 20 to the second position, the user actuates therelease button 40 to release thelatch 38 and pulls thehandle assembly 20 away from thebody portion 14. Upon removing thehandle assembly 20, the user can apply a spot treatment to the surface to be cleaned by pressing the actuator 26 on thehandle assembly 20 to distribute solution from the dispensingnozzle 24. -
