The present disclosure provides a surface cleaning apparatus that includes a housing including a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.

A cleaner is disclosed. The cleaner includes a first cleaning module including a left spin mop and a right spin mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module configured so as to come into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module configured to supply water to the first cleaning module and including a water tank disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A surface cleaner may have various features including an engagement mechanism secured to an agitator support frame and positioned to be pivoted by an agitator lift lever as the agitator lift lever translates, the pivoting engagement mechanism lifting the agitator support frame and the agitator secured thereto from a lowered position to a raised position. Other features may include a projection to limit belt slack when the agitator assembly is raised, a compact detent mechanism for releasing a spine assembly in an upright surface cleaner, a compact motor drive assembly, a self-priming centrifugal pump, a fluid-dispensing system having a high flow operating state and a low flow operating state, and a clean-out tray in which a base of the surface cleaner may be docked.

Disclosed are a robot cleaner and a maintenance device for the same. The robot cleaner includes a body, a traveling module for moving the body, a bottom portion disposed in front of the traveling module for sliding along a floor when the body is moved, and a collection portion disposed in front of the bottom portion, the collection portion having therein a space for collecting foreign matter on the floor. The maintenance device includes a suction port configured to be inserted into the collection portion and a suction channel for guiding the movement of the air suctioned through the suction port.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360 degree turns to facilitate the treatment of difficult to access portions of the floored surface.

A method of controlling a moving robot is provided. The method of controlling a moving robot includes the steps of: (a) performing a basic motion of the moving robot which moves on a rotating mop; (b) measuring the slip rate of the moving robot; and (c) controlling the travel of the moving robot.

A cleaner includes a body, a left spin-mop module and a right spin-mop module configured to perform mopping, and a water supply module configured to supply water to the left spin-mop module and the right spin-mop module. The water supply module includes a water tank to store water therein, a pump to pressurize the water in the water tank to move the water to the left spin-mop module and the right spin-mop module, a first supply pipe connecting the water tank and the pump, a common pipe connected to the pump, the common pump configured to guide movement of the pressurized water from the pump, a first branch pipe configured to guide a first portion of the water in the common pipe to the left spin-mop module, and a second branch pipe configured to guide a second portion of the water in the common pipe to the right spin-mop module.

A moving robot is provided. The moving robot includes: a main body forming the exterior appearance; a moving means for moving the main body; a bumper configured to protrude on the outer perimeter of the main body; impact sensors placed at an angle on the main body to sense the movement of the bumper; and pressure parts formed in a bent shape at the end of the impact sensors.

Disclosed is a robot cleaner including a body having a module location portion, a traveling module for moving the body, and a sliding module having a body location portion detachably coupled to the module location portion, the sliding module being configured to slide along a floor when the body is moved. A mop fixing unit for fixing a replaceable mop is provided between the module location portion and the body location portion.

A cleaner includes a body forming an external appearance, a rotating plate provided at a lower side of the body, a mop unit coupled to a lower side of the rotating plate so as to be in contact with a floor, a spin shaft connected to an upper side of the rotating plate so as to rotate the rotating plate, a water supply reservoir configured to surround a periphery of the spin shaft and spaced apart from the spin shaft so as to define a water supply space, and a water supply module configured to supply water to the water supply space. The rotating plate forms a water supply hole configured to interconnect the water supply space and the lower side of the rotating plate.
