The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways.
The base 12 is movable over the surface 22 to be cleaned. In the illustrated embodiment, the base 12 includes wheels 24 to facilitate moving the base 12 over the surface 22. The base 12 includes a suction nozzle 26 in fluid communication with the vacuum source 20 and the recovery tank 18, the suction nozzle 26 being releaseably connected to the cleaning head 12, such that the suction nozzle 26 is removable in a downward direction from the bottom of the cleaning head 12. The cleaning fluid is drawn from the surface 22 through the suction nozzle 26 and into the recovery tank 18.
The base 12 further includes a distributor including a spray or distribution nozzle 28 in fluid communication with the supply tank 16. The distribution nozzle 28 dispenses the cleaning fluid toward the surface 22. In some embodiments, the supply tank 16 and the distributor are omitted such that the suction nozzle 26 draws debris and optionally fluid from the surface 22, but no fluid is added to the surface 22 by the floor cleaner 10. The distributor could alternatively be a drip bar, could be fed pressurized or gravity fed cleaning fluid, and could distribute cleaning fluid directly or indirectly (e.g., through a cleaning implement) onto the floor internally or externally of the base.
In the illustrated embodiment, the floor cleaner 10 includes a battery 30 that provides power to the vacuum source 20. In one embodiment, the battery 30 is a rechargeable lithium-ion battery. The floor cleaner 10 further includes a handle 32. The handle 32 includes a grip 34 and an actuator 36 adjacent the grip 34. The grip 34 is grabbed by the user to move the floor cleaner 10 along the surface 22 and to pivot the body 14 relative to the base 12. The actuator 36 controls the flow of cleaning fluid from the supply tank 16 through the distribution nozzle 28. The handle 32 further includes an extension 40 that extends from the body 14. The extension 40 includes a first end 42, a second end 44. The first end 42 is coupled to and adjacent the body 14. The second end 44 is adjacent the grip 34.
The floor cleaner 10 further includes an upper end 50 and a lower end 52 opposite the upper end 50. The handle 32 is adjacent the upper end 50 and the base 12 is adjacent the lower end 52. The floor cleaner 10 further include a front side 54 and a back side 56 opposite the front side 54. The suction inlet 26 is adjacent the front side 54.
The floor cleaner 10 further includes a suction conduit 58 having a first end fluidly connected to the suction nozzle 26 and a second end fluidly connected to the recovery tank 18. The suction conduit 58 directs fluid from the suction nozzle 26 into the recovery tank 18.
The recovery tank 18 is removably connected to the body 14 such that when the recovery tank 18 is full, a user can remove the recovery tank 18 from the body 14 and empty the recovery tank 18 before reconnecting the recovery tank 18 to the body. The recovery tank 18 includes an air outlet positioned on an upper surface of the recovery tank 18 to permit air to exit the recovery tank 18. In some embodiments, one or more filters remove particles from the air before the air exits the floor cleaner 10. The recovery tank 18 also includes a float valve that closes the air outlet as the fluid level in the recovery tank 18 reaches a maximum level to inhibit the fluid from leaking out of the air outlet on the upper surface of the recovery tank 18. The recovery tank 18 is connected to the body 14 by any suitable latching mechanism.
When the cover 64 is removed from the base 12, an agitator roll or brushroll 72 is accessible. The brushroll 72 is positioned near the bottom 60 of the base 12 adjacent the suction nozzle 26. The brushroll 72 is configured to engage the surface 22 during operation. The brushroll 72 is rotatable about an axis to agitate, wipe, scrub, etc. the surface 22 that is being cleaned. The floor cleaner 10 includes a motor that rotates the brushroll 72 about the axis. The brushroll 72 is operably connected to the motor by a transmission that may include a belt, pulleys, gears, and the like.
The brushroll 72 can include a tufted pile formed of microfibers covering substantially all of the brushroll 72. In another embodiment, the tufted pile covers a portion of the brushroll 72. The fiber may be yarn or may be monofilament fiber. The brushroll 72 may include an absorbent material, such as a mop roll. Optionally, the brushroll 72 may include a hydrophobic textile material. In one embodiment, the tufted textile material is formed by a tufted pile of fine hydrophobic fibers, such as hydrophobic nylons, polyesters, polyolefins, or other hydrophobic fibers arranged on the brushroll 72. The fibers can be made from any hydrophobic materials such as a flouropolymer such as polytetrafluoroethylene in one embodiment. In another embodiment, the fibers are coated with a hydrophobic coating or otherwise treated to be hydrophobic. In some embodiments, the brushroll includes tufted bristles arranged in a desired pattern, such a chevron or helical arrangement.
When the cover 64 is removed from the base 12 a first distribution coupling 74 is exposed. The first distribution coupling 74 is fluidly connected to the supply tank 16 and to the distribution nozzle 28.

The second end 86 of the suction nozzle 26 is configured to connect to the suction conduit 58 which directs fluid and debris into the recovery tank 18. The suction nozzle 26 can be connected to the base 12 by latches, screws, inter-engaging components or features, or any suitable fastener(s). In the illustrated embodiment, the suction nozzle 26 is connected by screws. To this end, the suction nozzle 26 may include one or more embossments for receiving a screw or other fastener, such as a first upwardly extending protrusion 90 and the housing includes a first upwardly extending recess 92 configured to receive the first upwardly extending protrusion 90. A fastener can extend through the first upwardly extending protrusion 90 and the first upwardly extending recess 92 to retain the suction nozzle 26 on the housing of the base 12. In other embodiments, the suction nozzle 26 includes a recess and the housing includes a protrusion. In one embodiment, the first upwardly extending protrusion 90 is provided for alignment of the nozzle to the base. In some embodiments, the recess 92 and the corresponding protrusion 90 are omitted. In other embodiments, the suction nozzle 26 and the housing include mating components that snap together or otherwise inter-engage to retain the suction nozzle 26 on the housing of the base 12. In some embodiments, no fastener is used to connect the first upwardly extending protrusion 90 in the first upwardly extending recess 92 because the suction nozzle 26 can be connected to the housing of the base 12 by other fasteners, latches, and/or inter-engaging components.
The brushroll 72 protrudes from the bottom 60 of the base 12 so that the brushroll 72 contacts the surface 22 being cleaned. Also, although the illustrated cleaning machine 10 includes only a single brushroll 72, in other embodiments, the cleaning machine 10 may include additional brushrolls parallel to the brushroll 72 and formed from the same or different materials. The brushroll 72 has an outer cleaning medium that contacts the surface 22. The cleaning medium includes a hydrophobic textile material in one embodiment.
In the illustrated embodiment, the base 12 further includes a second recess 110 and a third recess 112. The second recess 110 is sized and positioned to receive the second upwardly extending protrusion 106 when the suction nozzle 26 is connected to the base 12. The third recess 112 is sized and positioned to receive the third upwardly extending protrusion 108 when the suction nozzle 26 is connected to the base 12. In some embodiments, the recesses 106 and 108 are formed on the suction nozzle 26 and the protrusions 102 and 104 are formed on the base 12. In one embodiment, the second upwardly extending protrusion 106 and the third upwardly extending protrusion 108 are provided for alignment of the nozzle to the base. In some embodiments, the recesses 106 and 108 and the corresponding protrusions 102 and 104 are omitted. Other shapes, sizes and locations of recesses and protrusions can be utilized to properly position the suction nozzle 26 on the base 12.
In some embodiments, fasteners are configured to connect the second upwardly extending protrusion 106 to the second recess 110, and to connect the third upwardly extending protrusion 108 to the third recess 112. In some embodiments, each of the fasteners is screw that requires a tool to separate the suction nozzle 26 from the base 12. In other embodiments, each of the fasteners is a bayonet coupling, or a quick connect coupling that do not require a tool to separate the suction nozzle 26 from the base 12.
In some embodiments, one or more fasteners connect the suction nozzle 26 to the base 12. In some embodiments, the suction nozzle 26 is connected to the base 12 by one or more clips, a bayonet coupling, or a latch or quick connect coupling that does not require a tool to separate the suction nozzle 26 from the base 12. In some embodiments, the suction nozzle 26 is connected to the base 12 by one or more screws or bolts that can be removed with the use of a tool.
The present disclosure is directed to the cleaning head base 12 having a brushroll 72 that is removable from the top 62 of the cleaning head base in the upward direction U and the suction nozzle 26 that is removable from the bottom 60 of the cleaning head base 12 in the downward direction D.
