The present disclosure relates generally to an apparatus for cleaning or otherwise treating a floor or ground surface. Devices provided herein include various features to enhance the efficiency and efficacy of cleaning operations. Such devices includes, but are not limited to, bearing protector devices, cord and cable management devices, and ergonomic features useful with ride-on floor treating machines.

The present invention relates to a floor surfacing machine (1) comprising a frame (2) that is carried by a first wheel (3) and a second wheel (4). The floor surfacing machine (1) further comprises a first motor (6), a handle arrangement (7), at least one planetary head (15) that is rotatably mounted to the frame (2) and at least one satellite surfacing head (19, 20, 21) that is rotatably mounted to the planetary head (15), where the first motor (6) is arranged to propel the planetary head (15). The floor surfacing machine (1) comprises a first control unit (10), and a remote control panel (11) which in turn comprises a second control unit (12) that is arranged to communicate with the first control unit (10). The floor surfacing machine (1) also comprises a second motor (22) that is arranged to propel the satellite surfacing heads (19, 20, 21) such that the planetary head (15) and the satellite surfacing heads (19, 20, 21) are independently operable.

A cleaner includes a case which includes an inlet for suctioning in rubbish on a surface to be cleaned, a driver which is provided inside the case and includes a motor which generates power, a drum body which is provided in the inlet and configured to receive the power from the driver and rotate, and a drum blade arranged in an outer circumferential direction of the drum body and formed with a blade air current hole through which air suctioned in through the inlet passes.

A device (1) for automatically performing an activity, in particular for cleaning dirty surfaces, having at least one sensor (3) and at least one drive element (4). The drive element (4) divides the device (1) into a rear region (11) and a front region (12), on the basis of the intended direction of movement (B). The sensor (3) is a mechanical sensor which is arranged in the front region (12) of the device (1) and is used to determine, by contact with the floor, a change in the height of the floor.

The present disclosure relates to a liquid container and an autonomous cleaning robot. The liquid container may include a container case and a cleaning cloth that is removable and mounted on the container case. The cleaning cloth may include a first guiding member disposed thereon. The container case may include a second guiding member. The first guiding member and the second guiding member cooperate with each other to define an assembly direction of the cleaning cloth. The cleaning cloth can be installed correctly by defining the assembly direction of the first guiding member and the second guiding member.

A surface cleaning apparatus adapted for movement across a surface to be cleaned. The surface cleaning apparatus can dock within a storage tray and charge a power supply. Electrical contacts on the surface cleaning apparatus and the storage tray can be shielded when the surface cleaning apparatus is not docked within the storage tray. Furthermore, the storage tray can include a reservoir for a self-cleaning mode.

Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A cleaning machine may include: a first brush comprising a first brush shaft extending in a left-right direction and a first brush body held by the first brush shaft; a second brush comprising a second brush shaft extending in the left-right direction and a second brush body held on the second brush shaft; a brush supporting member supporting each of the first brush and the second brush such that the first brush and the second brush are rotatable; a body supporting the brush supporting member such that the brush supporting member is pivotable; and a pivot mechanism configured to pivot the brush supporting member with respect to the body. At least the first brush may move with respect to the body in an up-down direction when the brush supporting member pivots with respect to the body.

The method may include putting fresh cleaning liquid in the trolley bucket assembly bucket and the vacuum recovery tank; and, while propelling the system across hard surface flooring: dispensing fresh cleaning liquid from the bucket onto flooring by adjusting the spigot; spreading fresh cleaning liquid on flooring with the liquid spreader assembly; and vacuuming soil and cleaning liquid from flooring into the tank with the squeegee head assembly. The method may further include, when a desired amount of cleaning liquid has been dispensed from the bucket, or a desired amount of cleaning liquid has been vacuumed into the tank: stopping dispensing of cleaning liquid from the bucket; stopping propelling of the system; and transferring a desired amount of cleaning liquid from the tank to the bucket via the cleaning liquid transfer outlet. In addition, the method may include resuming propelling the system across flooring while also: dispensing; spreading; and vacuuming.

A robotic obstacle-crossing device mainly includes a wheel body and an obstacle-crossing body, wherein the wheel body includes a wheel part, a first obstacle-crossing part and a second obstacle-crossing part. When the sweeping robot tilts, the plurality of first recessed portions and the plurality of second recessed portions provided on the periphery of the first obstacle-crossing part and the second obstacle-crossing part provide a climbing function. In addition, when the sweeping robot encounters obstacles or steps, the obstacle-crossing body can provide robot the function of the obstacle-crossing or climbing, thereby reducing the number of situations when the sweeping robot is trapped or unable to effectively climb upon encountering an obstacle or a steep road surface.
