An autonomous floor cleaner or floor cleaning robot can include an autonomously moveable housing and a drive system for autonomously moving the autonomously moveable housing over a surface to be cleaned based on inputs from a controller. A brush chamber, a debris receptacle, and a supply tank can be formed as a unitary assembly removable from the autonomously moveable housing.

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.

A floor cleaning machine is provided. The floor cleaning machine includes a solution tank for a cleaning solution. A pre-canister sensor receives the cleaning solution and measures the concentration of any dissolved solids. A canister assembly receives a portion of the cleaning solution from the pre-canister sensor and dissolves portions of a solid chemical form into the cleaning solution thereby forming blended droplets. The canister assembly has a spray nozzle positioned vertically above the solid chemical form. A post-canister sensor receives a mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. The post-canister sensor measures the concentration of any dissolved solids within the mixture of the cleaning solution from the pre-canister sensor and the blended droplets from the canister assembly. A comparison of the baseline and post-canister measurements outside of a desired range results in replacement of the solid chemical form.

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 method for operating a floor cleaning machine on a floor surface. The floor cleaning machine includes a cleaning-liquid container, a dirty-liquid container, a chassis for moving the floor cleaning machine over the floor surface, a cleaning means and a dirty-liquid take-up means. The method includes: sensing an amount of cleaning liquid supplied from the cleaning-liquid tank to the cleaning means within a first time interval while moving the floor cleaning machine; sensing an amount of dirty liquid being removed from the dirty-liquid take-up means to the dirty-liquid container within a second time interval while moving the floor cleaning machine; comparing the sensed amount of cleaning liquid against a first threshold value; comparing the sensed amount of dirty liquid against a second threshold value; outputting a first fault signal if the sensed amount of cleaning liquid is greater than the first threshold value and the sensed amount of dirty liquid is less than the second threshold value.

A suction foot assembly having a suction foot with a suction foot holder, a coupling portion, and a suction foot interface. One of the coupling portion and a coupling end of the suction foot interface has a pin portion. The other of the coupling portion and the coupling end has first and second clamping elements that are mutually opposite, have free ends, and run concavely in such a manner that a receptacle portion in which the pin portion is received is formed between the clamping elements. The mutual spacing of the free ends of the clamping elements is less than the spacing of the clamping elements in the receptacle portion. One or both clamping elements is/are elastically deformable to permit the pin portion to be moved by way of the free ends out of the receptacle portion and into the latter.

A hand-guided floor cleaning machine with a base, a driven brush element that is configured to engage with a floor surface in a cleaning plane, a fluid applicator for applying cleaning liquid to the floor surface, and a suction foot that is secured via a mount on the base and configured to receive dirty liquid from the floor surface. The mount has a first pivoting arm, which is articulated on the base with the machine end so as to be pivotable about a first pivot axis which runs parallel to a cleaning plane, a guide wheel, which is coupled to the first pivoting arm, and a second pivoting arm, which is articulated on the first pivoting arm so as to be pivotable about a second pivot axis which runs parallel to the first pivot axis. The suction foot is attached to a distal end of the second pivoting arm.

The invention relates to a floor cleaning device comprising a floor unit which is assigned a direction of advance parallel to a floor surface to be cleaned; a tool which, in an operating state, contacts the floor surface, the tool being movable relative to the floor surface by means of a drive; a guide member for guiding the floor cleaning device; and a joint assembly connecting the floor unit and the guide member in an articulate manner. When in a maneuvering operating state, the guide member can pivot about a first pivot axis and can be fixed or temporarily supported in the first pivot axis plane. As a result of the pivoting movement of the guide member about the first pivot axis, an advance effect brings about a moment of rotation of the floor unit on the floor surface that benefits the maneuvering of the floor cleaning device.

A control system for a robotic floor cleaning machine configured to perform a cleaning operation along a cleaning path can comprise a controller, and a plurality of sensors. The controller can be configured to control autonomous movement of the robotic floor cleaning machine along the cleaning path and autonomous performance of the cleaning operation. The plurality of sensors can be configured to sense a location of the robotic floor cleaning machine relative to surroundings of the robotic floor cleaning machine. At least two sensors from the plurality of sensors are configured to locate the robotic floor cleaning machine in overlapping areas of the surroundings.

A nozzle for a cleaner has a nozzle housing, which has a nozzle base and a drain hole for discharging water from the nozzle housing. The nozzle also has a rotary cleaning unit disposed below the nozzle housing. The rotary cleaning unit has a rotation plate that can be attached to a mop. The nozzle has a driving unit that includes a driving motor for driving the rotary cleaning unit. The nozzle also has a control board for controlling the drive motor. In addition, the nozzle has a water tank detachably mounted on an upper side of the nozzle housing. The water tank stores water and supplies the water to the rotary cleaning unit.
