A cleaning robot includes a main body having an exterior portion extending along a perimeter of the main body; wheels that are drivable to move the robot; a rotation shaft; and a holder coupled to the rotation shaft to support a cleaning pad. The rotation shaft and the holder are rotatable along a rotation axis that is perpendicular to the surface to be cleaned, and the rotation shaft is laterally movable in a direction perpendicular to the rotation axis to: a pop-in position in which the rotation shaft and the holder are under the main body and not protruding beyond the exterior portion of the main body, and a pop-out position in which the rotation shaft is under the main body and not protruding beyond the exterior portion and the holder is partially under the main body and partially protruding beyond the exterior portion of the main body.

In one aspect, an autonomous cleaning robot includes a drive configured to propel the robot along the floor surface and a tank assembly. The tank assembly includes a reservoir, left and right receptacles, and a handle extending across a cover of the tank assembly, the handle being moveable between a first position and a second position, wherein when the handle is in the second position, the tank assembly is locked in position. The tank assembly also includes left and right latch assemblies receivable by the left and right receptacles, respectively. Each latch assembly includes a moveable assembly configured to lock the tank assembly in position when the handle is in the second position.

A cleaning device for cleaning a surface is described. The cleaning device includes at least one cleaning element and a wetting system to supply a cleaning liquid to the at least one cleaning element. The wetting system is operable in one of at least one normal operation mode and a boost operation mode involving an increased supply rate of the cleaning liquid with respect to the at least one normal operation mode. During start-up of the cleaning device in a wet cleaning mode thereof, a start-up operation mode of the wetting system is determined to be one of the normal operation mode or the boost operation mode on the basis of assessment of an actual value of at least one parameter that is indicative of whether or not the at least one cleaning element is in a wet cleaning condition.

A nozzle arrangement faces a surface to be cleaned includes a first suction body and a second suction body located at a distance relative to each other. The nozzle arrangement further includes a level setting mechanism that puts the first suction body and the second suction body at different overall levels relative to the surface in a normal, operational orientation of the nozzle arrangement on the surface. In this way, cleaning performance of the nozzle arrangement can be improved. Additionally, or alternatively, it is possible to have a suction enhancing mechanism for at least partially closing at least one of the first suction body and the second suction body to one of the surface and an internal air conduit of the nozzle arrangement.

A surface cleaning apparatus having an upright assembly, a power source, and a coiled electrical cable. The upright assembly including a frame and a telescoping handle at last partially extending from the frame and movable between an extended position and a contracted position. The coiled electrical cable being provided within a portion of the telescoping handle and configured to uncoil or coil when the telescoping handle is moved between the extended position and the contracted position.

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 floor cleaner that includes a recovery tank having a top side, a bottom wall opposite the top side, and a sidewall that extends from the bottom wall and defines a perimeter of the recovery tank, the bottom wall and the sidewall at least partially define a storage volume of the recovery tank. The recover tank further includes an inlet aperture, the inlet aperture adjacent the storage volume and the top side and configured to direct fluid into the storage volume. A baffle wall is connected to the sidewall and the baffle wall faces toward the inlet aperture. An inlet aperture axis extending centrally through the inlet aperture and the inlet aperture axis extends through the baffle wall.

A robot cleaner includes a main body, a water tank including a turbidity sensor and a water level sensor, and a pair of rotary mops configured to move the main body while rotating in contact with a floor. A drive motor rotates the pair of rotary mops and a nozzle supplies water from the water tank to the rotary mop. A rotary mop controller varies an output current of the drive motor based on signals from the water tank sensors. A controller determines whether the water tank is contaminated based on the output current of the drive motor received from the rotary mop controller.

A robot cleaner includes a main body forming an exterior and having a water tank housing formed at a rear side thereof. The water tank housing may form a space in which a water tank is mounted. At least one spin mop is rotatably provided at a lower side of the main body, moving the main body by rotating, and configured to clean a floor using water in the water tank. A supply nozzle is provided at one side of the water tank housing, and when connected to a discharge nozzle of the water tank, communicates with the discharge nozzle to supply water stored in the water tank to each of the spin mops. The robot cleaner further includes a locking device rotatably provided at a position spaced apart from a circumferential surface of the water tank housing, and configured to secure the water tank in the water tank housing when mounted or to release the water tank by pushing backward on the water tank.

A surface cleaning apparatus having a fluid delivery system and a fluid recovery system is provided with a housing including an upright body and a base coupled with the upright body. Cleaning fluid and electrical wiring can be routed between the upright body and the base via a yoked spine section of the upright body.
