A robot vacuum cleaner includes a main body that moves along a surface, draws in dust from the surface, filters the dust, and discharges air. A water tank is detachably mounted on a lower surface of the main body, and a damp cloth is mounted to the water tank. The water tank stores water in a filling space and supplies water from the filling space through a water supply unit mounted on a lower surface of the water tank to the damp cloth. An air inlet is formed on an upper surface of the water tank. An air inflow member selectively opens the air inlet to allow outside air to flow into the filling space when the main body moves, and closes the air hole when the main body stops moving.

A system and method for dispensing a treatment fluid is provided. The system includes a surface maintenance machine, a fluid reservoir, an air blower, and one or more fluid dispensing systems. The one or more fluid dispensing systems each include one or more nozzles in fluid communication with the air blower. The air blower generates an air pressure and dispenses air through the one or more nozzles while the treatment fluid is dispensed through the one or nozzles. The dispensing of air and treatment fluid dispenses the treatment fluid in a mist, fog, or spray to a surface. A method for dispensing a treatment fluid is also provided. The method includes generating an electrically charged treatment fluid and dispensing the electrically charged treatment fluid from the one or more nozzles to a surface.

A method for controlling a robot cleaner includes receiving map information and an image transmitted from a further cleaner. The method also includes identifying position information of the further cleaner by comparing the image received from the further cleaner with an image captured by the robot cleaner and performing cleaning while traveling along with the further cleaner.

A cleaning assembly including a floor scrubber and a self-cleaning device matched with the floor scrubber is provided. The floor scrubber includes a housing connected to a handle. A motor is arranged in the housing. A scrubbing disc is arranged below the housing and is driven by the motor to rotate. The self-cleaning device includes a barrel connected to a support member used for supporting the floor scrubber. A wiper member is arranged in the barrel. When the floor scrubber is placed in the barrel to be dried, the support member supports the floor scrubber, and the wiper member abuts against the scrubbing disc; and when the scrubbing disc rotates or the wiper member moves, water and/or dirt on the scrubbing disc are/is wiped off by the wiper member.

Embodiments of the present application provide robots and vehicles including a chassis, a drive shaft mounted to the chassis, an integrated steering column, and a set of proximity sensors. The drive shaft may be connected to a drive wheel. The integrated steering column may be operably connected to the drive shaft for steering the drive wheel. The set of proximity sensors may be mounted to the integrated steering column. The set may be configured to scan an ambient environment, where the set includes a first proximity sensor and a second proximity sensor respectively oriented towards each of the opposing lateral sides of the chassis.
