Walk-behind floor treatment machine comprising: a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means, wherein a lower region of the handle portion is pivotably connected to the wheel means so that the handle portion may pivot through a generally vertical arc, and wherein a handle pivot lock mechanism is provided in which the adoption of a predetermined handle portion orientation permits one or more locking feature to act on one or more corresponding constraint feature so as to prevent pivoting movement of the handle portion with respect to the linkage, whereby tilting back of the locked handle portion causes a corresponding rise of the linkage and base portion with work head so as to lift them from the floor surface, wherein a squeegee suction device is provided for collecting and entraining liquid lifted from a floor surface over which the machine travels, the squeegee suction device being attached to the wheel means via one or more trailing arm which is attached at one end region to the squeegee device and at the opposite end region is pivotably attached to the wheel means for pivoting co-axially about the said transverse axis of rotation, the arrangement being such that the trailing arm and squeegee may pivot up or down about the transverse axis as they trail behind the treatment machine.

The invention relates to a cleaning system, comprising a cleaning cart and an external accessory device, wherein the cleaning cart comprises a frame having rollers for moving on a ground surface, at least one receptacle for receiving and/or carrying cleaning utensils, and an interaction device having a hand-actuatable interaction element, wherein the accessory device is portably configured and a user application program for processing cleaning-related information is executably stored on the accessory device and/or operable via the accessory device, wherein the interaction device and the accessory device are coupleable with one another via a communication connection, and wherein, depending on an actuation of the interaction element by the user, input information for operation of the user application program is transmittable from the interaction device to the accessory device and is processable by the accessory device. The invention further relates to a method for operating a cleaning system.

The present disclosure relates to the field of cleaning robot technology, and in particular to a cleaning robot system. The cleaning robot system includes a base station and a cleaning robot. The base station is independent to the cleaning robot of the cleaning robot system. The base station includes a base station body and a mop member cleaning device arranged on the base station body. The mop member cleaning device is configured to clean a mop member of the cleaning robot. Based on the base station, the cleaning robot system is capable of automatically cleaning the mop member with no need for users to change or clean the mop member frequently, which is helpful to free consumers from house cleaning, thus relieving the burden on the consumers, and also helpful to clean the mop member in time so as to ensure a better effect in next cleaning.

A wheel assembly for a robotic cleaner may include a frame, a moveable arm pivotally coupled to the frame, a driven wheel rotatably coupled to the moveable arm such that the driven wheel pivots with the moveable arm, and a biasing mechanism configured to urge the driven wheel towards an extended position, the biasing mechanism being coupled to the frame and spaced apart from the moveable arm.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, and a controller for controlling the operation of the autonomous floor cleaner. The drive system can include at least one drive wheel for driving the housing across a surface to be cleaned. The drive wheel can be selectively moved from an engaged or in-use position to a disengaged or maintenance position. In the disengaged or maintenance position, the wheel is disengaged from the autonomously moveable housing such that it can be pivoted, extended, removed, or otherwise moved farther away from the autonomously moveable housing.

A mobile disinfection device (200) includes a disinfection chamber (203) coupled to a propulsion system (228) configured for moving along a surface (236) to be disinfected. The disinfection chamber defines a closed distal end (205), an open proximal end (206) and a surrounding wall (207) impervious to the radiation and having opposing front and rear portions and opposing side portions, respective proximal front, rear and side edges of which are propelled by the propulsion system close to the surface to be disinfected. A radiation source (260) is mounted inside the disinfection chamber for irradiating the surface through the open proximal end. The propulsion system includes a peripheral seal (304) surrounding a proximal edge of the wall and configured to obstruct radiation that might otherwise escape from inside the disinfection chamber.
