Tread structures, wave motion navigational controls, and ramp up recovery controls are provided to an autonomous floor cleaner to reduce wheel slippage. The floor cleaner delivers liquid to the floor as part of the cleaning process. Wheels on the device are provided with relatively deep peripheral grooves to minimize the contact surfaces of a sprocket wheel and to accommodate the layer of liquid on the floor. In the event of wheel slippage, or to prevent wheel slippage, the device is designed to move forward with a slight side-to-side wave action caused by periodically altering the relative speeds of two drive wheels. There is also provided a slippage recovery mode where the drive wheels shut down or greatly slow when severe slippage is sensed, followed by a slow ramp up of speed.

A floor cleaning device (10) includes a housing (40) and a container (43) removably received by the housing. A suction nozzle (18, 18′, 18″) is fluidly connected with the container and with a suction source (52) when the container is received by the housing. A filter (114) is selectively fluidly connected with the container and with the suction source. A float (170) selectively closes the fluid connection of the filter with the container. The filter and the float may be removable as a unit (42) from the cleaning device. The nozzle may be removable, allowing an appropriate nozzle to be selected according to the type of floor surface to be cleaned.

A bare floor cleaner has a foot with a dry suction nozzle and a handle assembly pivotally connected to the foot assembly. A diverter mounted in the working air conduit between the foot assembly and the handle assembly is movable by movement of the handle assembly between a dry suction position and a wet mop position for selectively at least partially blocking working air flow from the dry suction nozzle to a collection assembly. A fluid delivery system includes a user operated trigger for actuating the fluid delivery system to distribute fluid in the wet mop position and deactivating a motor / fan assembly. A trigger lock prevents cleaning solution from being distributed when the handle is in dry mode position. The fluid delivery system includes a heating element to raise the temperature of the cleaning solution before it is distributed to the surface to be cleaned. Support glides on the foot reduce the surface area contact between the foot pad and the surface to be cleaned.

A bare floor cleaner for wet and dry bare floor surfaces comprises a base with wet and dry suction nozzles and a handle pivotally connected to the base. A diverter mounted in the working air conduit between each of the dry suction nozzle and the wet suction nozzle to a recovery tank is movable by movement of the handle between a dry suction position and a wet suction position for selectively at least partially blocking working air flow from the wet suction nozzle and the dry suction nozzle, respectively, to the recovery tank. A shut-off valve is mounted in the recovery tank to prevent fluid communication between a suction source and the recovery tank when the amount of liquid in the recovery tank reaches a first predetermined amount with the handle forward and a second predetermined amount with the handle rearward.

The invention relates to a cleaning brush for a floor cleaner, in particular, a self-propelled and self-steering floor cleaner, including at least one brush unit having a brush body defining a brush axis and being provided with cleaning bristles and having a first end and a second end, the at least one brush unit including at the first end or in the region of the first end a torque receiver device for coupling with a drive device of the floor cleaner. To provide such a cleaning brush which can be reliably mounted on a floor cleaner in a constructionally simple way, the at least one brush unit includes a bearing device for mounting on the floor cleaner, which is arranged between the first end and the second end. The invention also relates to a floor cleaner with a cleaning brush, in particular, a self-propelled and self-steering floor cleaner.
