Definitions
- Surface cleaning apparatuses are well-known devices for removing dirt from a variety of surfaces such as carpets, hard floors, or other fabric surfaces such as upholstery.
- Such surface cleaning apparatuses can include various cleaning systems, such as a vacuum collection system, a fluid delivery system, and/or a fluid recovery system.
- a typical extraction cleaner e.g. deep cleaner
- a fluid delivery system and a fluid recovery system can be embodied in one of a number of typical architectures, including upright, portable or handheld cleaners, canister, unattended (e.g. a spot cleaner), and autonomous (e.g., a robot).
- surface cleaning apparatus To communicate with the user, surface cleaning apparatus have user interfaces that can visually or audibly convey information to a user. Such communication has traditionally been limited, and may provide insufficient information to the user. The location of user interfaces has also been restricted by the architecture of the apparatus, and often requires a particular line of sight between the user and the interface. It can therefore be difficult to know when information is being conveyed while operating the surface cleaning apparatus or when the user is away from the apparatus. Accordingly, a need remains for improving user experience and facilitating interaction between the user and the surface cleaning apparatus.
- a surface cleaning apparatus includes a cleaning head adapted to move over a surface to be cleaned, a housing coupled with the cleaning head, at least cleaning system selected from a vacuum collection system, a fluid delivery system, and a fluid recovery system, a first user interface on the housing, and a second user interface on the cleaning head.
- the first user interface has a mode select input control to select a mode of operation of the surface cleaning apparatus and status indicators representing the modes of operation of the surface cleaning apparatus.
- the second user interface has a status display having duplicate status indicators representing the modes of operation of the surface cleaning apparatus.

Description
- The present application claims the benefit of U.S. Provisional Application No. 63/299,438, filed Jan. 14, 2022, which is incorporated herein by reference in its entirety.
- Surface cleaning apparatuses are well-known devices for removing dirt from a variety of surfaces such as carpets, hard floors, or other fabric surfaces such as upholstery. Such surface cleaning apparatuses can include various cleaning systems, such as a vacuum collection system, a fluid delivery system, and/or a fluid recovery system. For example, a typical extraction cleaner (e.g. deep cleaner) includes a fluid delivery system and a fluid recovery system, and can be embodied in one of a number of typical architectures, including upright, portable or handheld cleaners, canister, unattended (e.g. a spot cleaner), and autonomous (e.g., a robot). A typical wet/dry vacuum cleaner adapted for cleaning hard and soft floor surfaces can also include a fluid delivery system and a fluid recovery system, and may deposit cleaning fluid at a lower flow rate than a typical extraction cleaner. Other common types of surface cleaning apparatuses are vacuum cleaners, mops, sweepers, and the like.
- To communicate with the user, surface cleaning apparatus have user interfaces that can visually or audibly convey information to a user. Such communication has traditionally been limited, and may provide insufficient information to the user. The location of user interfaces has also been restricted by the architecture of the apparatus, and often requires a particular line of sight between the user and the interface. It can therefore be difficult to know when information is being conveyed while operating the surface cleaning apparatus or when the user is away from the apparatus. Accordingly, a need remains for improving user experience and facilitating interaction between the user and the surface cleaning apparatus.
- A surface cleaning apparatus with improved user interface features is provided herein to improve user experience.
- According to one aspect of the disclosure, a surface cleaning apparatus includes a cleaning head adapted to move over a surface to be cleaned, a housing coupled with the cleaning head, at least cleaning system selected from a vacuum collection system, a fluid delivery system, and a fluid recovery system, a first user interface on the housing, and a second user interface on the cleaning head. The first user interface has a mode select input control to select a mode of operation of the surface cleaning apparatus and status indicators representing the modes of operation of the surface cleaning apparatus. The second user interface has a status display having duplicate status indicators representing the modes of operation of the surface cleaning apparatus. The first and second user interfaces are structured so that when the surface cleaning apparatus is on, a status indicator corresponding to a selected mode of operation is illuminated and visible to a user on each of the housing and the cleaning head.
- According to another aspect of the disclosure, a surface cleaning apparatus includes a cleaning head adapted to move over a surface to be cleaned, a housing coupled with the cleaning head, at least cleaning system selected from a vacuum collection system, a fluid delivery system, and a fluid recovery system, a first user interface on the housing, and a second user interface on the cleaning head. The first user interface has a mode select input control to select a mode of operation of the surface cleaning apparatus. The second user interface has a status display having status indicators representing the modes of operation of the surface cleaning apparatus, and is structured so that when the apparatus is off, the status display is blank, and when the apparatus is on, a status indicator corresponding to a selected mode of operation is illuminated and visible to a user.

As discussed in further detail below, theapparatus 10 is provided with user interface features consistent with one or more aspects of the disclosure, the details of which are described in further detail below. As explained herein, the user interface features enable theapparatus 10 to accept user inputs for controlling theapparatus 10, function as a communication output device, and/or provide an improved user experience. Theapparatus 10 may include a first user interface (“first UI”) 12 and a second user interface (“second UI”) 14 to accomplish one or more of the aforementioned functions. - The
apparatus 10 includes a cleaning head adapted to move over a surface to be cleaned, a housing coupled with the cleaning head, and at least cleaning system. OneUI 12 can be provided on the housing and theother UI 14 can be provided on the cleaning head. TheUIs - As illustrated in
FIG. 1 , thesurface cleaning apparatus 10 can be an upright floor cleaner including a cleaning head in the form of a base 16 adapted to move over a surface to be cleaned and a housing in the form of anupright body 18 coupled with the base 16 to direct the base 16 over the surface to be cleaned. As used herein, the term upright floor cleaner is intended to refer to various types of floor cleaners including, but not limited to, upright floor cleaners, stick floor cleaners, convertible floor cleaners (e.g., a floor cleaner capable of being used as an upright- or stick-type cleaner as well as a handheld cleaner), a lift-off floor cleaners (e.g., a floor cleaner capable of being used as an upright-type cleaner as well as a canister type cleaner), extraction cleaners (also referred to as carpet cleaners or extraction cleaners), steam cleaners, mopping cleaners, and the like, or combinations thereof. For example, an upright floor cleaner may be an extraction cleaner. - For purposes of description related to the figures, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” “inner,” “outer,” and derivatives thereof shall relate to the disclosure as oriented in
FIG. 1 from the perspective of auser 20 behind theapparatus 10, which defines the rear of theapparatus 10. However, it is to be understood that the disclosure may assume various alternative orientations, except where expressly specified to the contrary. - In one example, the
upright floor cleaner 10 can be a vacuum cleaner including at least a vacuum collection system for creating a partial vacuum to suck up dirt from a floor surface and collect the removed dirt in a space provided on the vacuum cleaner for later disposal. - In another example, the
upright floor cleaner 10 can be a wet/dry vacuum cleaner including at least a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned and a vacuum collection system for creating a partial vacuum to suck up the cleaning fluid and dirt from a floor surface and collect the removed dirt in a space provided on the vacuum cleaner for later disposal. The fluid delivery system may be configured to deliver liquid and/or steam to the surface to be cleaned. - In yet another example, the
upright floor cleaner 10 can be an extraction cleaner or deep cleaner, and can include a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned and a fluid recovery system for removing the cleaning fluid and dirt from the surface to be cleaned and storing the recovered cleaning fluid and dirt. The fluid delivery system may be configured to deliver liquid and/or steam to the surface to be cleaned. In comparison to the wet/dry vacuum cleaner, an extraction cleaner typically delivers cleaning fluid at a higher flow rate to the surface to be cleaned. For example, the flow rate of an extraction cleaner may deliver 10× to 20× that of a wet/dry vacuum cleaner. - In still another example, the
upright floor cleaner 10 can be a wet mopping or sweeping apparatus, including a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned and a mopping or sweeping system for removing cleaning fluid and dirt from the surface to be cleaned without the use of suction. The fluid delivery system may be configured to deliver liquid and/or steam to the surface to be cleaned. - The base 16 can comprise any type of base, foot, or other cleaning head suitable for the purposes described herein, including being moved over a floor surface to be cleaned. The base 16 may include any of a suction nozzle, an agitator (e.g. a brushroll, a pad, etc.), a squeegee, a wheel, a pump, a heater, a motor, a tank, a filter, a dispenser, a battery, a wireless communication module, a hose, and the like, or any combination thereof.
- The
upright body 18 can comprise any type of elongated handle, wand, body, or combination thereof suitable for the purposes described herein, including for a user to maneuver thefloor cleaner 10 over a floor surface to be cleaned. Theupright body 18 can be adapted to pivot about one or more axes through a range of angles relative to thebase 16. Optionally, theupright body 18 can be configured so as to swivel about its longitudinal axis in addition to pivoting relative to thebase 16.FIG. 1 shows one example of theupright body 18 reclined to a use position. Theupright body 18 may also be movable to and retainable in an upright storage position. - The
body 18 ofFIG. 1 includes ahandle 22 having agrip 24, which may be shaped to be comfortably gripped by one hand of theuser 20. Other components of thebody 18 may include any of a pump, a motor, a tank, a filter, a dispenser, a battery, a wireless communication module, a wand, a hose, and the like, or any combination thereof. Optionally, thebody 18 can have acarry handle 25 to facilitate lifting and carrying theentire floor cleaner 10. - The
first UI 12 can comprise an input UI having at least one user input control operably connected to one or more components or systems of thefloor cleaner 10 to affect and control its operation. Non-limiting examples of input controls include buttons, triggers, toggles, keys, switches, touchscreen icons, or the like, or any combination thereof. - The
first UI 12 is configured to accept user inputs to control thefloor cleaner 10, including systems or components thereof. For example, the input controls may affect and control the operation of a vacuum collection system, a fluid delivery system (e.g., a liquid delivery system and/or a steam delivery system), a fluid recovery system, a mopping system, a sweeping system, and the like, or any combination thereof. As yet another example, the input controls may affect and control the operation of a motor, a brushroll, a liquid dispenser, a steam dispenser, a pump, a filter, a supply tank, a recovery tank, a battery, a wireless communication module, and the like, or any combination thereof. - The
second UI 14 can comprise an output UI including at least one status indicator, or a status display including a plurality of status indicators, that communicates a condition or status of the floor cleaner, including systems and components thereof, to the user. Non-limiting examples of status indicators include visual indicators such as lights (e.g., LEDs), icon displays, textual displays, graphical displays, or the like, or any combination thereof. Thesecond UI 14 can also include an auditory output component, such as a speaker. - The
second UI 14 is configured to indicate status information relating to thefloor cleaner 10, including systems or components thereof. For example, the display may indicate a cleaning mode of thefloor cleaner 10, a Wi-Fi connections status of the floor cleaner, and the like, or any combination thereof. As another example, the display may indicate the status of a vacuum collection system, a fluid delivery system (e.g., a liquid delivery system or a steam delivery system), a fluid recovery system, a mopping system, a sweeping system, and the like, or any combination thereof. As yet another example, the display may indicate that status of a motor, a brushroll, a liquid dispenser, a steam dispenser, a pump, a filter, a supply tank, a recovery tank, a battery, a wireless communication module, and the like, or any combination thereof. - While the
first UI 12 is referred to herein as an input UI, in some embodiments thefirst UI 12 may have an output functionality as well. For example, thefirst UI 12 may, in some embodiments, include at least one status indicator that communicates a condition or status of the floor cleaner, including systems and components thereof, to the user. In other embodiments, thefirst UI 12 solely accepts input, and does not provide outputs to the user. - Likewise, while the
second UI 14 is referred to herein as an output UI, in some embodiments thesecond UI 14 may have an input functionality as well. For example, thesecond UI 14 may, in some embodiments, include at least one user input control operably connected to one or more components or systems of thefloor cleaner 10 to affect and control its operation. In other embodiments, thesecond UI 14 solely provides output, and does not accept inputs from the user. - The first and
second UIs floor cleaner 10. Thehandle 22 can include thefirst UI 12. Thefirst UI 12 can conveniently be located adjacent to thegrip 24, so that theuser 20 may hold thegrip 24 in one hand and operate thefirst UI 12 with the same hand. For example, theuser 20 may wrap their palm and fingers around thegrip 24 and operate thefirst UI 12 using the thumb of the same hand. Similarly, aninput control 26 can conveniently be located adjacent to thegrip 24 andfirst UI 12. For example, theuser 20 may operate theinput control 26 using the forefinger of the same hand holding thegrip 24. Conveniently, in one arrangement, theUI 12 is disposed on a front side of thegrip 24 and theinput control 26 is disposed on a rear side of thegrip 24. - Although shown on an upper portion of the
handle 22, adjacent thegrip 24, other locations for thefirst UI 12 are possible, including locations where theuser 20 must hold thegrip 24 in one hand and operate thefirst UI 12 with their other hand. It may be preferred that thefirst UI 12 is in a location that theuser 20 holding thegrip 24 may operate thefirst UI 12 without having to bend down or take their hand off thegrip 24. Such locations include, but are not limited to, on thecarry handle 25, on aportion 28 of thehandle 22 other than thegrip 24, or on anupper portion 30 of theupright body 18.FIG. 1 shows some non-limiting examples of alternative locations for thefirst UI 12 in phantom line. In some aspects, thefirst UI 12 may include a first portion on thehandle 22 and a second portion in another location, such as thecarry handle 25,portion 28, orupper portion 30, for example. - The cleaning head, in
FIG. 1 thebase 16, can include thesecond UI 14. Thesecond UI 14 can conveniently be located in a field ofview 32 of theuser 20 operating the apparatus. As used herein, the user's “field of view” 32 is the observable area a person can see through their eyes. When operating a surface cleaning apparatus, theuser 20 commonly looks down the apparatus toward a surface being cleaned and/or toward the cleaning head orbase 16 moving over the surface. For example, to operate theupright floor cleaner 10, theuser 20 may stand generally behind thefloor cleaner 10 and hold thegrip 24 in one hand. During operation, theuser 20 may commonly switch between looking straight out and down thefloor cleaner 10 toward a floor surface 34 being cleaned. For example, during operation, theuser 20 may shift their focus across the field ofview 32 as they observe the surface they are in the process of cleaning (the portion of the surface thebase 16 is traveling over and/or about to travel over in the next instant) and the portion of the surface they intend to move the base 16 to next as they proceed with the cleaning the surface according to the user's particular travel pattern across the surface. As such, their field ofview 32 includes thebase 16 of thefloor cleaner 10, and may also include alower front portion 36 of theupright body 18. Locating thesecond UI 14 on the base 16 positions thesecond UI 14 in the user's field ofview 32. - During operation of the
floor cleaner 10, theuser 20 can quickly glance back and forth between the floor surface 34 being cleaned and thesecond UI 14. Even when the user's attention is focused on the floor surface 34, changes displayed on thesecond UI 14 are within the user's field ofview 32, and so may readily draw the user's attention to the information conveyed bysecond UI 14. - Typically, a range of up to 60 degrees from a horizontal sight line H is a comfortable visible range for most people without straining the eyes. Thus, in some configurations the
UI 14 can be located within 60 degrees from the horizontal sight line H of theuser 20. Further, to be inclusive of the anthropometric height range of typical users, theUI 14 can be located within the field ofview 32 ofuser 20 having a height within a range of a 5th percentile female to a 95th percentile male. - In the case of an upright architecture, like the
floor cleaner 10 ofFIG. 1 , thesecond UI 14 may be on a portion of the base 16 that is within the user's field ofview 32 when theupright body 18 is reclined to the use position. When in the upright storage position, thesecond UI 14 may be blocked or partially blocked from view by theuser 20 standing behind thefloor cleaner 10, but may be visible to a user approaching the floor cleaner 10 from the front or side of thefloor cleaner 10. In other configurations, thesecond UI 14 may be within the user's field ofview 32 regardless of whether it is in the reclined use position or upright storage position. - Although shown on the
base 16, and particularly on atop side 38 of thebase 16, other locations for thesecond UI 14 are possible. It may be preferred that thesecond UI 14 is in a location that theuser 20 holding thegrip 24 may view thesecond UI 14 without having to bend down or take their hand off thegrip 24. Such locations include, but are not limited to, thelower front portion 36 of theupright body 18.FIG. 1 shows some non-limiting examples of alternative locations for thesecond UI 14 in phantom line. - The
floor cleaner 10 can further include amain controller 40 operably coupled with the various function systems and components of thefloor cleaner 10, including the first andsecond UIs main controller 40 can further be operably coupled with one or more sensors for receiving input about thefloor cleaner 10 or its environment, and can use the sensor input to control the operation of thefloor cleaner 10. - The
UIs FIGS. 2 and 3 are diagrams showing a cross-section of one embodiment of thefirst UI 12 and one embodiment of thesecond UI 14, respectively. - Referring to
FIG. 2 , one embodiment of thefirst UI 12 is shown, and includes multiple user input controls 50A, 50B, 50C, 50D. Four input controls are shown, although it is understood that more than four or less than four input controls are possible. - The input controls 50A-50D can include a
switch 52A-D within theupright body 18 and a switch cover orbutton 54A-D that is on an exterior surface of thefloor cleaner 10 or forms an exterior surface of thefloor cleaner 10. As shown inFIG. 2 , thebutton 54A-D are on thehandle grip 24. In operation, a user presses one of thebuttons 54A-D to actuate the associatedswitch 52A-D, and theswitch 52A-D controls one or more components or systems of thefloor cleaner 10 to affect and control its operation. - Each input control 50A-50D is preferably provided with an
icon 56A-D. Theicons 56A-D can be in the form of graphics, symbols, words, or a combination thereof. Various icons are possible, and preferably give the user an indication of the purpose of the input control 50A-50D. - The
icons 56A-D can be added to thebutton 54A-D by pad printing, attaching a label, adhering a graphic, or the like. In the embodiment ofFIG. 2 , the input controls 50A-C includeicons 56A-C added to theirbutton 54A-C by pad printing, and are visible at all times to the user. In another embodiment, theicons 56A-D can next to thebutton 54A-D. - At least one of the user input controls, here input control 50D, can have a contextual or context-based icon 56D structured so that, when the function associated with the input control 50D is not available to the user, the icon is not visible to the user. The contextual icon 56D is only visible at an appropriate time and under appropriate conditions for selection of the function associated with the input control 50D. Thus, the contextual icon 56D informs the user when a specific feature is available.
- In some embodiments, when the function associated with the input control 50D is not available to the user, pressing the input control 50D does not affect or control the associated function. Thus, display of the contextual icon 56D to the user is associated with an enablement of the associated function that allows the associated function to be selected by the user.
- The contextual icon 56D can be a back-lit icon structured so that, when the function associated with the input control 50D is not available to the user, the icon 56D is hidden or dead, e.g. not illuminated by an
LED 58 or other illumination source, and when the function associated with the input control is available to the user, the icon 56D is illuminated and visible to the user. The back-lit icon 56D can be in the form of a graphic, symbol, word, or a combination thereof. For example, the input control 50D can have a back-lit graphic on theswitch cover 54D. In another example, the input control 50D can have a back-lit dot or other symbol adjacent to theswitch cover 54D, which may itself include a graphic or other icon that is always visible. - The
switches 52A-D andLED 58 can be mounted on aPCB 62. As used herein, unless otherwise noted, the term “PCB” includes a printed circuit board having a plurality of electrical and electronic components that provide operational control to thefloor cleaner 10. The PCB includes, for example, a processing unit (e.g., a microprocessor, a microcontroller, or another suitable programmable device) and a memory (e.g., a read-only memory (“ROM”), a random access memory (“RAM”), an electrically erasable programmable read-only memory (“EEPROM”), a flash memory, or another suitable magnetic, optical, physical, or electronic memory device). The processing unit is connected to the memory and executes instructions (e.g., software) that is capable of being stored in the RAM (e.g., during execution), the ROM (e.g., on a generally permanent basis), or another non-transitory computer readable medium such as another memory or a disc. Additionally or alternatively, the memory is included in the processing unit (e.g., as part of a microcontroller). Software stored in memory includes, for example, firmware, program data, one or more program modules, and other executable instructions. The processing unit is configured to retrieve from memory and execute, among other things, instructions related to the control processes and methods described herein. The PCB can also include, among other things, a plurality of additional passive and active components such as resistors, capacitors, inductors, integrated circuits, and amplifiers. These components are arranged and connected to provide a plurality of electrical functions to the PCB including, among other things, signal conditioning or voltage regulation. For descriptive purposes, a PCB and the electrical components populated on the PCB are collectively referred to as a controller. Thus, thePCB 62 of thefirst user interface 12 and the electrical components populated on thePCB 62 may be referred to as a first user interface controller. - Referring to
FIG. 3 , one embodiment of thesecond UI 14 is shown, and includes a hiddenstatus display 70 with a plurality ofstatus indicators 72A-C. Thesecond UI 14 can be structured so that when the floor cleaner is off, thestatus display 70 is blank and thestatus indicators 72A-C are hidden or dead, e.g. not illuminated, and when the floor cleaner is on, thestatus indicators 72A-C may selectively be illuminated and visible to the user. As explained in further detail below, thestatus indicators 72A-C can be back-lit icons that are hidden or dead, e.g. not illuminated, under a first condition and may selectively be illuminated and visible under a second condition. Threestatus indicators 72A-C are shown, although it is understood that more than three or less than three status indicators are possible. - The
status display 70 includes amasking layer 74 on a portion 76 of thebase 16, which may be translucent or transparent, i.e. it permits light from anLED 78A-C or other illumination source positioned internally of the base 16 to emit light therethrough. Themasking layer 74 blocks light from theLEDs 78A-C in thebase 16. Various masking layers are possible, including, but not limited to, opaque paint, such as black or gray paint. - The
status indicators 72A-C are icons etched in themasking layer 74. The etching extends down to the surface of the portion 76 of thebase 16, so that light can pass through the etched icon from the associatedLED 78A-C. The LEDs 78A-C can emit visible light in one or more colors, such as, but not limited to, white, blue, orange, red, green, yellow, and the like. TheLEDs 78A-C can be configured to emit light in specific colors, wavelength ranges, and or patterns to convey information to the user. Alternatively or in addition, theLEDs 78A-C may be adjustable by the user to emit light in different wavelength ranges or colors. TheLEDs 78A-C can be mounted on aPCB 80. ThePCB 80 of thesecond user interface 14 and the electrical components populated on thePCB 80 may be referred to as a second user interface controller. - The
status display 70 includes a light-transmittinglayer 82 applied over themasking layer 74 to cover the etched icons. The light-transmittinglayer 82 can be a second paint layer that is light-transmitting so that when one of theLEDs 78A-C is on, the associated icon is visible to the user. When theLED 78A-C associated with the icon is off, the icon is not visible to the user. - One or more additional layers can be applied on top of the light-transmitting
layer 82. For example, aclear coating 84 of polyurethane or similar material can be applied to protect the status display from wear or damage. Also, while the masking and light-transmittinglayers -
FIG. 4 shows anupright floor cleaner 110 with wet cleaning capabilities according to another aspect of the present disclosure. Thefloor cleaner 110 can include multiple cleaning systems, including a liquid delivery system and a recovery system. In some embodiments, thefloor cleaner 110 also include a steam delivery system. Thefloor cleaner 110 may include afirst UI 112 and asecond UI 114 to accept user inputs for controlling the cleaning systems, function as a communication output device for the cleaning systems, and/or provide an improved user experience. Thefloor cleaner 110 can, for example, be a wet/dry vacuum cleaner or an extraction cleaner. - With both steam and liquid delivery systems, the
floor cleaner 110 can selectively deliver liquid and/or steam to the surface to be cleaned. Thefirst UI 112 can have appropriate input controls for user control of the systems, including dispensing liquid only or dispensing liquid and steam simultaneously to the surface to be cleaned. Thesecond UI 114 can output status information to the user. - The
floor cleaner 110 includes a cleaning head in the form of a base 116 adapted to move over a surface to be cleaned and a housing in the form of anupright body 118 coupled with the base 116 to direct the base 116 over the surface to be cleaned. Thebody 118 includes ahandle 122 having agrip 124 and atrigger 126. The various cleaning systems and components thereof can be supported by either or both thebase 116 and theupright body 118. - A moveable
joint assembly 142 can connect the base 116 to theupright body 118 for movement of theupright body 118 about at least one axis. In the embodiment shown herein, theupright body 118 can pivot up and down about at least one axis relative to thebase 116. Thejoint assembly 142 can alternatively comprise a universal joint, such that theupright body 118 can swivel about its longitudinal axis in addition to pivoting relative to thebase 116. Theupright body 118 can pivot, via thejoint assembly 142, between an upright or storage position (not shown) and a reclined or use position, an example of which is shown inFIG. 4 , in which theupright body 118 is pivoted rearwardly to form an acute angle with the surface to be cleaned. Wiring and/or conduits can optionally supply electricity, air, liquid and/or steam between theupright body 118 and thebase 116, or vice versa, and can extend though thejoint assembly 142. As such, in some embodiments, a portion of the cleaning systems can extend through thejoint assembly 142. -
FIG. 5 is a schematic view of various functional systems of thefloor cleaner 110. The liquid delivery system includes a source of cleaningfluid 144, at least oneliquid dispenser 146 supplied with liquid cleaning fluid from the source of cleaningfluid 144, and aliquid supply path 148 from the source of cleaning fluid to aliquid dispenser 146. - The
fluid source 144 can stored cleaning fluid in liquid form. The cleaning fluid can comprise one or more of any suitable cleaning fluids, including, but not limited to, water, compositions, concentrated detergent, diluted detergent, etc., and mixtures thereof. For example, the cleaning fluid can comprise water. In another example, the cleaning fluid can comprise a mixture of water and concentrated detergent. - The liquid delivery system can include a flow controller for controlling the flow of fluid from the
source 144 to theliquid dispenser 146. In one configuration, the flow controller can comprise apump 150, which pressurizes thepath 148 and controls the delivery of liquid cleaning fluid to theliquid dispenser 146. In one example, thepump 150 can be a centrifugal pump. In another example, thepump 150 can be a solenoid pump. - The release of cleaning liquid from the
liquid dispenser 146 can be controlled by thetrigger 126. Thetrigger 126 can operate avalve 149 in thepath 148, where depressing thetrigger 126 opens thevalve 149 to release cleaning liquid to thedispenser 146. Release of thetrigger 126 closes thevalve 149 and stops liquid dispensing. As described in further detail below, in some embodiments, operation of thevalve 149 upon depression of thetrigger 126 can be mode-dependent. In other words, depending on a selected cleaning mode of thefloor cleaner 110, depression of thetrigger 126 may or may not open theliquid valve 149. - In another configuration of the fluid delivery system, the
trigger 126 can operate thepump 150, where depressing thetrigger 126 activates thepump 150 and releasing thetrigger 126 turns thepump 150 off. In such a configuration,valve 149 may be integrated with thepump 150 or may be absent from thefloor cleaner 110. - In another configuration of the fluid delivery system, the
pump 150 can be eliminated and the flow controller can comprise a gravity-feed system having a valve fluidly coupled with an outlet of thesource 144, whereby when the valve is open, fluid will flow under the force of gravity to theliquid dispenser 146. - The
liquid dispenser 146 can comprise any structure, such as a nozzle, a spray tip, or a manifold, and can comprise at least one liquid outlet for dispensing liquid cleaning fluid to the surface to be cleaned. Thedispenser 146 can be positioned to deliver liquid cleaning fluid directly to the surface to be cleaned, or indirectly by delivering liquid cleaning fluid onto an agitator (not shown). In one non-limiting example, thedispenser 146 delivers liquid cleaning fluid onto a brushroll. In another non-limiting example, thedispenser 146 delivers liquid cleaning fluid between two horizontally-rotating brushrolls. - The liquid delivery system can include other conduits, ducts, tubing, hoses, connectors, valves, etc. fluidly coupling the components of the liquid delivery system together and providing the
liquid supply path 148. - The
fluid source 144 can include at least one supply container for storing a supply of cleaning fluid. In yet another configuration, the fluid delivery system can have an additional supply container (not shown) for storing another cleaning fluid. For example the first supply container can store water and the second supply container can store a cleaning agent such as detergent. In embodiments where multiple supply containers are provided, thefloor cleaner 110 can have with a mixing system for controlling the composition of the cleaning fluid that is delivered to the surface. - The steam delivery system includes a source of cleaning fluid, a
heater 152 for heating the cleaning fluid, asteam dispenser 154 to dispense steam, and asteam supply path 156 from the source of cleaning fluid to thesteam dispenser 154. Theheater 152 preferably heats the cleaning fluid to around 100±10° C., alternately about 90 to 100° C., alternatively about 95 to 98° C. Some non-limiting examples of asuitable heater 152 include, but are not limited to, a flash heater, a boiler, an immersion heater, and a flow-through steam generator. - The steam delivery system can share the same
fluid source 144 as the liquid delivery system. In another embodiment, thefloor cleaner 110 can include a separate supply container (not shown) for storing a cleaning fluid for the steam delivery system. In embodiments where thefluid source 144 is shared, amanifold splitter 158 splits liquid between thesteam supply path 156 and theliquid supply path 148. - The steam delivery system can include a flow controller to control the flow of fluid from the
source 144 to theheater 152. In one configuration, the flow controller can comprise apump 160 that pressurizes thepath 156 and controls the delivery of heated fluid to thesteam dispenser 154. In one example, thepump 160 can be a centrifugal pump. In another example, thepump 160 can be a solenoid pump. - The release of steam from the
steam dispenser 154 can be controlled by thetrigger 126. Thetrigger 126 can operate avalve 157 in thepath 156, where depressing thetrigger 126 opens thevalve 157 to release steam to thesteam dispenser 154. Release of thetrigger 126 closes thevalve 157 and stops steam dispensing. As described in further detail below, in some embodiments, operation of thevalve 157 upon depression of thetrigger 126 can be mode-dependent. In other words, depending on a selected cleaning mode of thefloor cleaner 110, depression of thetrigger 126 may or may not open thesteam valve 157. For example, depending on the cleaning mode, operation of thetrigger 126 may open theliquid valve 149 only, thesteam valve 157 only, or both thevalves - In yet another embodiment, a separate
steam input control 159 selectively operates thesteam valve 157 to control steam dispensing, while thetrigger 126 selectively operates theliquid valve 149 to control liquid dispensing. A user may operate bothcontrols - In another configuration of the fluid delivery system, the
trigger 126 can operate thepump 160, where depressing thetrigger 126 activates thepump 160 and releasing thetrigger 126 turns thepump 160 off. In such a configuration,valve 157 may be integrated with thepump 160 or may be absent from thefloor cleaner 110. - The
steam dispenser 154 can comprise any structure, such as a nozzle or a manifold, and can comprise at least one steam outlet for dispensing steam toward the surface to be cleaned. Thedispenser 154 can be positioned to deliver steam directly to the surface to be cleaned, or indirectly by delivering steam onto an agitator or cleaning pad. In one non-limiting example, thesteam dispenser 154 delivers steam onto the surface to be cleaned in front of thebase 116. - The steam delivery system can include other conduits, ducts, tubing, hoses, connectors, valves, etc. fluidly coupling the components of the system together and providing the
supply path 156 from the cleaningfluid source 144 to thesteam dispenser 154. - In certain embodiments, the liquid provided to the
liquid dispenser 146 does not pass through theheater 152 and/or is otherwise unheated, and is at the same temperature as thefluid source 144. In other embodiments, the liquid provided to theliquid dispenser 146 passes through a heater (not shown) or is otherwise heated to a temperature that is less than the temperature of the steam dispensed by thesteam dispenser 154. Such a heater can be located downstream of thefluid source 144 and upstream of thepump 150. In yet another example, exhaust air from a motor-cooling pathway for a motor/fan assembly can be applied to theliquid supply path 148 to heat the liquid. - The recovery system can include a
suction nozzle 162, a suction source including avacuum motor 164 in fluid communication with thesuction nozzle 162 for generating a working air stream through arecovery path 166, and arecovery container 168 for separating and collecting fluid and dirt from the working airstream for later disposal. Aseparator 170 can be formed in a portion of therecovery container 168 for separating fluid and entrained dirt from the working airstream. - The
suction nozzle 162 can be provided on the cleaning head orbase 116 adapted to move over the surface to be cleaned. Thesuction nozzle 162 can including a suction pathway having a nozzle inlet defining an inlet of therecovery path 166. - The
floor cleaner 110 can include anagitator 172 to agitate the surface to be cleaned. In one non-limiting example, theagitator 172 is positioned within thesuction nozzle 162, with the suction nozzle inlet positioned in close proximity to theagitator 172 to collect liquid and debris directly from theagitator 172. In another non-limiting example, theagitator 172 is positioned outside thesuction nozzle 162, with thesuction nozzle 162 disposed forwardly of theagitator 172 on the cleaning head. The former example may be suitable for a floor cleaner comprising a wet/dry vacuum cleaner, while the later example may be suitable for a floor cleaner comprising an extraction cleaner. - Some examples of
agitators 172 include, but are not limited to, a horizontally-rotating brushroll, dual horizontally-rotating brushrolls, one or more vertically-rotating brushrolls, a stationary brush, or a cleaning pad. In one non-limiting example, theagitator 172 is a single horizontally-rotating brushroll, theliquid dispenser 146 delivers liquid cleaning fluid onto the brushroll, and thesuction nozzle 162 substantially surrounds the brushroll. In another non-limiting example, theagitator 172 is two horizontally-rotating brushrolls, theliquid dispenser 146 delivers liquid cleaning fluid between two horizontally-rotating brushrolls, and thesuction nozzle 162 is disposed forwardly of the brushrolls andliquid dispenser 146. - In the case of a moving
agitator 172, a drive assembly including anagitator motor 174 can drive theagitator 172. A drive transmission (not shown) operably connects themotor 174 with theagitator 172 for transmitting rotational motion of themotor 174 to theagitator 172. - The
floor cleaner 110 can also be provided with above-the-floor cleaning features (not shown), including, but not limited to, an accessory hose and an above-the floor cleaning tool with its own suction inlet and/or fluid dispenser. - Electrical components of the cleaner 10, including the
heater 152, pumps 150, 160,vacuum motor 164, andagitator motor 174, are electrically coupled to apower source 176, which can comprise a power cord plugged into a household electrical outlet or a battery for cordless operation. Thefirst UI 112 can have appropriate input controls for user control of one or more of theheater 152, pumps 150, 160,vacuum motor 164, andagitator motor 174, thereby controlling the cleaning systems of thefloor cleaner 110. For example, cleaning modes can have associated operating parameters for theheater 152, pumps 150, 160,vacuum motor 164, and/oragitator motor 174, such that user selection of a cleaning mode will operate those components according to the associated operating parameters. Thesecond UI 114 can output status information regarding the selected cleaning modes to the user. -
FIG. 6 is a schematic view showing one configuration of theUIs floor cleaner 110, along with thehandle 122 andbase 116. In this embodiment, thefloor cleaner 110 is a wet/dry vacuum cleaner having a hard floor mode, an area rug mode, and a steam mode. The steam mode can operate in conjunction with the hard floor mode or the area rug mode. - The
first UI 112 has an on/off button, e.g. apower button 178, to activate and de-active the vacuum motor 164 (FIG. 5 ). By default, pressing thepower button 178 to activate thevacuum motor 164 can operate thefloor cleaner 110 in the hard floor mode. Pressing thepower button 178 may also turn theheater 152 on. In other embodiments, the default cleaning mode can be the area rug mode or the last mode selected. Other default operating modes for thefloor cleaner 110 are possible, including a default mode in which pressing thepower button 178 activates an electronic component of thefloor cleaner 110 other than thevacuum motor 164. - The
first UI 112 has a mode select input control ormode button 180 to select between different modes when thefloor cleaner 110 is on. Example modes include a hard floor mode and an area rug mode. Themode button 180 can operate a toggle switch that cycles through the cleaning modes. For example, repeated pressing of themode button 180 can cycle between the hard floor and area rug modes. - Referring back to
FIG. 6 , thefirst UI 112 has asteam button 184 to select the steam mode. Thesteam button 184 can operate a toggle switch that cycles the steam mode on and off. The steam mode can have associated operating parameters for theheater 152, pumps 150, 160,vacuum motor 164, and/or agitator motor 174 (FIG. 5 ). In one example, in the steam mode, thepump 160 is activated. Therefore, pressing thesteam button 184 activates and de-actives thepump 160. Optionally, there is a warm-up period after turning theheater 152 on via thepower button 178 during which steam is not available to be dispensed. - As noted above, the steam mode can be structured to operate in conjunction with the hard floor mode, area rug mode, or another cleaning mode. For example, pressing the
steam button 184 to select a steam mode may include maintaining operation of the currently-selected hard floor or area rug mode. In another embodiment, pressing thesteam button 184 to select the steam mode may deactivate the currently-selected mode. - With reference to
FIG. 5 , the cleaning modes can have associated operating parameters for theheater 152, pumps 150, 160,vacuum motor 164, and/oragitator motor 174. In one example of the hard floor mode, thevacuum motor 164,liquid pump 150, andbrush motor 174 are activated, with thevacuum motor 164 operating at a first power level. In one example of the area rug mode, thevacuum motor 164,liquid pump 150, andbrush motor 174 are activated, with thevacuum motor 164 operating at a second power level, which is higher than the first power level. In another example, the flow rate of liquid in the hard floor mode is higher than in the area rug mode. In one example of the steam mode, thevacuum motor 164,liquid pump 150,heater 152,steam pump 160, andbrush motor 174 are activated, with thevacuum motor 164 operating at a power level of the selected hard floor or area rug mode. - As noted above, in all cleaning modes, the release of cleaning fluid (e.g., cleaning liquid and/or steam based on the selected mode) can be controlled by the
trigger 126. Alternatively, release of cleaning liquid can be controlled by thetrigger 126 and release of steam can be controlled by thesteam input control 159. - Table 1 below lists some non-limiting examples of operating parameters for the cleaning modes, including whether liquid and/or steam is dispensed, and whether the brush motor is on or off. Other operating parameters for the cleaning modes and other cleaning modes are possible.

TABLE 1 Cleaning Liquid Steam Vacuum Brush Mode Dispensing Dispensing Motor Motor Hard Floor ON OFF LOW ON Area Rug ON OFF HIGH ON Steam ON ON LOW/HIGH ON - The
first UI 112 has a clean-outcycle button 186 to activate and de-activate a self-cleaning mode of thefloor cleaner 110 in which thefloor cleaner 110 executes an automatic, unattended clean-out cycle. During the clean-out cycle, cleaning liquid is sprayed on the agitator 172 (FIG. 5 ) while theagitator 172 rotates. Liquid is extracted and deposited into therecovery container 168, thereby also flushing out thesuction nozzle 162 and therecovery path 166. One non-limiting example of an automatic, unattended clean-out cycle is disclosed in U.S. Pat. No. 11,160,431, issued Nov. 2, 2021, which is incorporated herein by reference in its entirety. Other clean-out cycles are possible. In another embodiment, the clean-outcycle button 186 can be provided elsewhere on thefloor cleaner 110, such as on a carry handle 125 (FIG. 4 ) of thefloor cleaner 110. - The
power button 178,mode button 180, andsteam button 184 can haveicons cycle button 186 can have a contextual or context-basedicon 196 that is displayed when a clean-out cycle is needed and/or when a clean-out cycle is ready to be executed. - During operation, the user can select the
mode button 180 and/orsteam button 184 to toggle through multiple cleaning modes. With the arrangement of theUI 112 on thehandle 122 the user can conveniently hold thehandle grip 124 in one hand and use the thumb of the same hand to toggle themode button 180 and/orsteam button 184 until the desired mode is selected. The selected cleaning mode is displayed on thebase 116 by thesecond UI 114. - The
second UI 114 includes a hiddenstatus display 198 on the base 116 with a plurality of status indicators. The individual status indicators can each include at least one icon in the form of graphics, symbols, words, or a combination thereof. InFIG. 6 , for example, thesecond UI 114 is shown with three status indicators, including a hard floor mode status indicator comprising anicon 200 in the form of a graphic depicting a hard floor, an area rug status indicator comprising anicon 204 in the form of a graphic icon depicting a rug, and a steam status indicator comprising anicon 202 in the form of a graphic icon depicting steam. The icons are each backlit by an illumination element (see,e.g. LED 78 inFIG. 3 ). The different shapes of the icons 200-204 provide a visual signal to the user that different modes are in operation. To provide a further visual distinction, the icons 200-204 may illuminate in different colors. For example, the hard floor andarea rug icons steam icon 204 can illuminate in a second color (e.g., orange). - When the
floor cleaner 110 is off, thestatus display 198 is blank and the icons 200-204 are hidden or dead, e.g. not illuminated. When thefloor cleaner 110 is on, the icons 200-204 may selectively be illuminated and visible to the user. For example, thehard floor icon 200 can be hidden or dead, e.g. not illuminated when thefloor cleaner 110 is not operating in the hard floor mode, and can be illuminated and visible when the hard floor mode is selected, e.g. usingmode button 180. Thearea rug icon 202 can be hidden or dead, e.g. not illuminated when thefloor cleaner 110 is not operating in the area rug mode, and can be illuminated and visible when the area rug mode is selected, e.g. usingmode button 180. Thesteam icon 204 can be hidden or dead, e.g. not illuminated when thefloor cleaner 110 is not operating in the steam mode, and can be illuminated and visible when the steam mode is selected, e.g. usingsteam button 184. Thestatus display 198 therefore shows the selected cleaning mode on thebase 116, within the user's field of view where the user naturally looks while cleaning a surface. -
FIG. 6 shows but one configuration for theUIs first UI 112 may not include thesteam button 184 and thesecond UI 114 may not include thesteam status icon 202. Other possible UI buttons, status indicators, and/or icons include, but are not limited to, other cleaning modes, battery status, Wi-Fi connection status, an empty supply container status, a full recovery container status, filter status, floor type, or any number of other status information. - The
floor cleaner 110 can include an additional light on the base 116 to visually convey a status, alert, or error by emitting visible light in different colors and/or light animations. The additional light can duplicate information conveyed by the first and/orsecond UI FIG. 6 , thefloor cleaner 110 has aheadlight 206 on the base 116 that is capable of being illuminated in multiple different colors. - The
headlight 206 can be structured so that theheadlight 206 is not illuminated when thefloor cleaner 110 is off and theheadlight 206 is illuminated when thefloor cleaner 110 is on. For example, theheadlight 206 is illuminated in a first color when thefloor cleaner 110 is on and a dispensing control is not actuated, and theheadlight 206 is illuminated in a second color when thefloor cleaner 110 is on and the dispensing control is actuated to dispense cleaning fluid. The dispensing control may be, for example, the trigger 126 (FIG. 5 ) that controls dispensing from theliquid dispenser 146 and/orsteam dispenser 154, or thesteam input control 159 that controls the dispensing of steam from thesteam dispenser 154. - In another example, the
headlight 206 is illuminated in a first color when thefloor cleaner 110 is on and the steam mode is not selected, and theheadlight 206 is illuminated in a second color when thefloor cleaner 110 is on and the steam mode is selected. - The
headlight 206 can be disposed on an upper side of thebase 116, making the emitted visible light easy to see from the typical operating position of the user behind and above thebase 116. Various locations for theheadlight 206 on thebase 116 are possible. In one embodiment, theheadlight 206 can be located behind acover 208, which can define thesuction nozzle 162 and/or a chamber for the agitator 172 (FIG. 5 ). Thecover 208 can be formed at least partially from a transparent, semi-transparent, or translucent material, and may, for example, allow a user to view visible light emitted from theheadlight 206 from the typical operating position of the user behind and above thebase 16. The emitted visible light passing through thecover 208 may be refracted or diffused such that a portion of thecover 208 appears to glow. - The
headlight 206 can include at least one light source comprising at least one light emitting element, such as, but not limited to, a light emitting diode (LED), an organic LED (OLED), a chip-on-board LED, a laser or laser diode, a regular lamp (arc lamp, gas discharge lamp, etc.), bulbs, or other light emitting device. Theheadlight 206 can comprise multiple light emitting elements, such as multiple LEDs. For an LED light source, an RGB LED may be preferred in order to produce lights in varying colors to indicate different statuses, errors, and/or alerts for thefloor cleaner 110. - The
floor cleaner 110 can have other lighting in addition to or as an alternative to theheadlight 206. Other lighting includes, but is not limited to, a UI edge light or a base edge light, examples of which are given below. - FIGS.7-14 show the
base 116 of thefloor cleaner 110 in various operational states and/or operating modes. InFIG. 7 , thefloor cleaner 110 is off, and accordingly thestatus display 198 of thesecond UI 114 is hidden. - In
FIG. 8 , thefloor cleaner 110 is powered on and in a default operational state. The default operational state may be the hard floor mode, and therefore thehard floor icon 200 illuminated and visible. - In
FIG. 9 , thefloor cleaner 110 is in the area rug mode, and therefore thearea rug icon 202 is illuminated and visible. - In
FIG. 10 , thefloor cleaner 110 is in the hard floor mode and a steam warm-up state of the steam mode, and therefore thehard floor icon 200 and thesteam icon 204 are illuminated and visible. Thefloor cleaner 110 may be in the steam warm-up state for a predetermined period of time after powering thefloor cleaner 110 on, during which theheater 152 is turned on and is warming up. One non-limiting warm-up period is 30 seconds. As indicated by illumination lines inFIG. 10 , during steam warm-up thesteam icon 204 can emit light in an animated state, e.g. with a change pattern and/or changing characteristics over time. Various animations are contemplated, including, but not limited to, a flashing animation. In a flashing animation, light intensity generally varies in a square wave fashion or in some other non-sinusoidal manner. In some examples, depending on the manner of use of thefloor cleaner 110, thesteam icon 204 may or may not exhibit the warm-up state status when the steam mode is selected. For example, in some cases the user may activate the steam mode after theheater 152 has already heated up and reached its predetermined operating set-point, such as after using thefloor cleaner 110 in a cleaning mode that does not utilize steam for a predetermined period of time. While the user is using thefloor cleaner 110 in the cleaning mode without steam, theheater 152 may be heating up such that when the user switches to a cleaning mode with steam, thefloor cleaner 110 is essentially ready to instantaneously dispense steam on demand and thus thesteam icon 204 is illuminated in visible. In another example, the user may wish to utilize a cleaning mode with steam right away upon powering on thefloor cleaner 110. In this scenario, thesteam icon 204 can emit light in an animated state while theheater 152 heats up, indicating to the user that steam is not yet ready for dispensing, once theheater 152 has heated up to the set-point suitable for generating steam for use in a steam cleaning mode, thesteam icon 204 can be illuminated in a steady state to indicate to the user that steam is now ready for dispensing on demand during cleaning. - In
FIG. 11 , thefloor cleaner 110 is in the hard floor mode and steam ready state of the steam mode, and therefore thehard floor icon 200 and thesteam icon 204 are illuminated and visible. Thefloor cleaner 110 may enter the steam ready state after the warm-up period. When steam is ready, thesteam icon 204 can illuminate in a steady state, e.g., with generally continuous, unchanging characteristics over a period of time. The change between animation of thesteam icon 204 and steady-state illumination of thesteam icon 204 indicates to the user that steam is ready for dispensing during cleaning. - While
FIG. 10-11 show thefloor cleaner 110 in the hard floor mode and the steam mode, thefloor cleaner 110 is also operable in the area rug mode and the steam mode. In this case, thestatus display 198 shows thearea rug icon 202 and thesteam icon 204. -
FIG. 12-13 show thefloor cleaner 110 in various dispensing states, where theheadlight 206 functions as the status indicator for dispensing. As noted above, theheadlight 206 is structured so that theheadlight 206 is not illuminated when thefloor cleaner 110 is off (FIG. 7 ) and theheadlight 206 is illuminated when thefloor cleaner 110 is on (FIG. 8-14 ). When thefloor cleaner 110 is on and not dispensing (FIG. 8-11 ), theheadlight 206 is illuminated in a first color (e.g., white) as indicated at 210. When thetrigger 126 is depressed, theheadlight 206 changes to another color (FIG. 12-13 ) to indicate the dispensing state to the user. Referring toFIG. 12 , in the hard floor or area rug mode, actuation of thetrigger 126 to dispense cleaning liquid illuminates theheadlight 206 in a second color (e.g., blue) as indicated as 212. Referring toFIG. 13 , in the steam mode, actuation of thetrigger 126 to dispense steam illuminates theheadlight 206 in the second color (e.g., blue) as indicated at 212. Release of thetrigger 126 in any mode can automatically change theheadlight 206 back to the first color, indicating to a user that cleaning fluid is no longer being dispensed. During dispensing, icons on thestatus display 198 corresponding to the operational mode can remain illuminated and visible. - For steam dispensing, the
headlight 206 can emit light in an animated state, e.g. with a change pattern and/or changing characteristics over time. Various animations are contemplated, including, but not limited to, a pulsing or breathing animation. In a breathing animation, light intensity increases and decreases in a generally sinusoidal manner. That is, the visible light gradually gets brighter until it reaches a peak and then gradually gets dimmer until it reaches a nadir (which may include the light completely shut off), and then this cycle repeats. -
FIG. 14 shows an alternative configuration for the steam dispensing state of thefloor cleaner 110. InFIG. 14 , thefloor cleaner 110 is in the hard floor mode and steam dispensing state, and therefore thehard floor icon 200 and thesteam icon 204 are illuminated and visible. Actuation of thetrigger 126 to dispense steam illuminates theheadlight 206 in a third color (e.g., orange) as indicated at 214, where the third color is different from the first or second color. Theheadlight 206 can illuminate in a steady state or in an animated state. Release of thetrigger 126 can automatically change theheadlight 206 back to the first color, indicating to a user that cleaning fluid is no longer being dispensed. - It will be understood that coordinating the operation of the
headlight 206 with dispensing of liquid and/or steam is optional and that aspects of the first and second UIs described herein can be utilized independently of theheadlight 206. - Referring to
FIGS. 15-16 , in one aspect of the disclosure, operation of the clean-out cycle may require that thefloor cleaner 110 be docked on atray 188 and/or another condition for self-cleaning be met. When not docked and/or when another condition for self-cleaning is not met, the clean-out cycle may be inoperable, and selection of the clean-outcycle button 186 will not activate the self-cleaning mode. - The
contextual icon 196 is displayed when a clean-out cycle is needed and/or when a clean-out cycle is ready to be executed. In one embodiment, theicon 196 can be hidden or dead, e.g. not illuminated, when a condition is not met, and can illuminate when a condition is met. For example, theicon 196 can be visible under certain conditions, including, but not limited to: (i) thefloor cleaner 110 being docked on the tray 188 (e.g.,FIG. 16 ); (ii) sufficient cleaning fluid to run a clean-out cycle is available in the supply container; (iii) sufficient space to collect cleaning fluid from a clean-out cycle is available in the recovery container; or any combination thereof. Theicon 196 is hidden under other conditions, including, but not limited to: (iv) thefloor cleaner 110 is not docked (e.g.,FIG. 15 ); (v) insufficient cleaning fluid to run a clean-out cycle is available in the supply container; (vi) insufficient space to collect cleaning fluid from a clean-out cycle is available in the recovery container; or any combination thereof. - In one embodiment, when the
floor cleaner 110 is docked on thetray 188, e.g. for recharging in the case of a cordless, battery-powered cleaner and/or after a cleaning session, the clean-outcycle icon 196 illuminates, indicating to the user that thefloor cleaner 110 is in a ready-to-self-clean state. Theicon 196 can illuminate in a steady state, e.g., with generally continuous, unchanging characteristics over a period of time, or illuminate in an animated state, e.g. with a change pattern and/or changing characteristics over time. Various animations are contemplated, including, but not limited to, a sunrise animation in which light intensity increases at a generally steady rate, e.g. theicon 196 gradually gets brighter until it reaches a peak illumination. After the clean-outcycle button 186 is pressed,icon 196 can switch from an animated state to a steady state, or may de-illuminate, indicating to a user that self-cleaning has been successfully initiated. In embodiments where theicon 196 remains illuminated during self-cleaning, theicon 196 can remain illuminated until the cycle is done and then may de-illuminate. - It is noted that the
tray 188 can physically support theentire floor cleaner 110. More specifically, the base 116 can be seated in thetray 188. Thetray 188 can further be configured for further functionality beyond self-cleaning and storage, such as for charging thefloor cleaner 110 in the case of a battery-powered or cordless cleaner. In such cases, thetray 188 may also be referred to as a docking station. -
FIG. 17 is a schematic view showing another configuration for theUIs floor cleaner 110. In this embodiment, thefloor cleaner 110 does not have a steam delivery system and the power source 176 (FIG. 5 ) is a battery. Thefirst UI 112 has thepower button 178,mode button 180, and clean-outcycle button 186 as described with respect toFIG. 6 , though arranged in a different layout. Additionally, theUI 112 has a Wi-Fi status indicator 216 that informs the user of a Wi-Fi connection status of thefloor cleaner 110. The Wi-Fi status indicator 216 can include a back-lit icon that is hidden when thefloor cleaner 110 is not connected to Wi-Fi and visible when thefloor cleaner 110 is connected to Wi-Fi. - The
second UI 114 includes abattery level indicator 218. In one embodiment, thebattery level indicator 218 can include agraphic icon 220 depicting a battery and a series of lights 222 (e.g., LEDs) inside thegraphic icon 220 that progressively illuminate to show a level of charge of battery. In an alternate example, thebattery level indicator 218 can include a number on thestatus display 198 that changes to indicate a level of charge of the battery. -
FIG. 18 is a schematic view showing yet another configuration for theUIs floor cleaner 110. In this embodiment, thefirst UI 112 has status indicators to indicate the mode selected via themode button 180, including a hard floor mode status indicator including anicon 224 in the form of a graphic depicting a hard floor and an area rug status indicator including anicon 226 in the form of a graphic icon depicting a rug. Theicons floor cleaner 110 is off, theicons floor cleaner 110 is on, one of theicons second UIs interfaces handle 122 or downwardly toward the surface to be cleaned. - In additional to the
icon 194, thesteam button 184 has astatus indicator 228 to indicate when the steam mode is “on” or active. Thestatus indicator 228 can comprise a back-lit bar or other symbol adjacent to thesteam button 184. The first andsecond UIs floor cleaner 110 is operating in the steam mode. -
FIG. 19 is a schematic view showing still another configuration for theUIs floor cleaner 110. In this embodiment, thefloor cleaner 110 is an extraction cleaner having a liquid cleaning mode, a liquid/steam cleaning mode, and a steam boost cleaning mode. - The
first UI 112 has an on/off button, e.g. apower button 230, to activate and de-active thevacuum motor 164 and the heater 152 (FIG. 5 ). By default, pressing thepower button 230 can operate thefloor cleaner 110 in the liquid/steam cleaning mode. In another embodiment, the default-cleaning mode can be the liquid cleaning mode or the steam boost cleaning mode, or the last mode selected. Other default operating modes for thefloor cleaner 110 are possible, including a default mode in which pressing thepower button 230 activates an electronic component of thefloor cleaner 110 other than thevacuum motor 164 and/or theheater 152. - The
first UI 112 has multiple mode select input controls or mode buttons, including a liquidcleaning mode button 232 to select the liquid cleaning mode, a liquid/steam cleaningmode button 234 to select the liquid/steam cleaning mode, and a steam boost cleaning mode button 326 to select the steam boost cleaning mode, respectively. In operation, a user can select one of the mode buttons 232-236, and the selected mode is displayed on thebase 116 by thesecond UI 114. - With reference to
FIG. 5 , the cleaning modes can have associated operating parameters for theheater 152, pumps 150, 160,vacuum motor 164, and/oragitator motor 174. In one example of the liquid/steam cleaning mode, thevacuum motor 164,liquid pump 150,heater 152,steam pump 160, andbrush motor 174 are activated, with theliquid pump 150 operating at a first flow rate.
