A cleaning device for a floor mopping machine comprises a bucket body for containing water, wherein a water removal member and a water feeding mechanism for conveying water from the bucket body to a wiping object of a floor mopping machine are arranged in the bucket body. During cleaning, the water feeding mechanism runs to convey water to the wiping object; and when water is removed, the water feeding mechanism stops running, and the wiping object of the floor mopping machine is wiped with the water removal member. Power of the water feeding mechanism is used for water feeding, and a wiping head is automatically cleaned, and can be wiped dry without any other operation after being cleaned; and the cleaning device is simple in structure, portable to use, less prone to damage and can be freely switched between a cleaning mode and a wipe-drying mode.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, a tank adapted to hold liquid, and a carry handle joined with the tank and/or the housing. The carry handle is movable between different positions, including a position in which the autonomous floor cleaner can be lifted via the carry handle while an inlet and/or outlet of the tank is blocked.

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 that faces the bottom wall, the inlet aperture adjacent the storage volume and the top side and configured to direct fluid into the storage volume. The inlet aperture is adjacent the sidewall of the recovery tank and the inlet aperture is a longitudinal shaped aperture having an aperture width and an aperture depth, the aperture width being greater than the aperture depth and the aperture width extends along the sidewall and the aperture depth extends along an inlet duct axis.

A cleaning machine has a housing, a supply tank, a suction nozzle, a suction source, and a recovery tank that includes a container having sidewalls projecting upwardly from a bottom wall thereby defining an open top, a cover connected to the open top of the container, and an air-liquid separator extending into the recovery tank from the open top and having a vertical sidewall, a lower wall extending laterally from a lower end of the vertical sidewall toward an adjacent sidewall of the sidewalls of the container. The vertical sidewall, the lower wall, and the adjacent sidewall define a separation chamber, the vertical sidewall includes a vertical rib extending outwardly from the vertical sidewall and into the separation chamber. The separation chamber includes a dirty fluid inlet receiving fluid from the suction nozzle through the cover, and a dirty fluid outlet directing fluid from the separation chamber into the container.

A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A cleaning base station including a cleaning body, a sewage collecting body, and a draining structure is provided. The cleaning body is defined with a filtering hole, and the sewage collecting body is connected with the cleaning body to collect sewage flowing out from the filtering hole. The draining structure is detachably connected with the sewage collecting body. The sewage collecting body can be disassembled from the draining structure to be cleaned since the draining structure and the sewage collecting body are detachably connected, which is very convenient.

An automatic cleaning device includes a mobile platform, a lifting station, a cleaning module, a liquid supplying module, and a collecting module. The mobile platform is configured to automatically move in a target direction on a surface to be cleaned. The lifting station is connected to the mobile platform and configured to move upwards or downwards with respect to the mobile platform. The cleaning module is connected to the lifting station and configured to clean the surface to be cleaned; the liquid supplying module is configured to provide cleaning liquid to the surface to be cleaned; and the collecting module is configured to collect the cleaning liquid. A height of the cleaning module of the automatic cleaning device is adjustable, and the automatic cleaning device has a great cleaning strength and is capable of collecting dirty cleaning liquid, thus, the automatic cleaning device can be applied broadly.

An extraction cleaner for a floor surface includes an extraction nozzle. The extraction nozzle that defines a fluid flow path having an elongated nozzle opening, and includes one or more stiffening elements that stiffens the walls around the nozzle opening to prevent collapsing or deformation of the extraction nozzle during use.

A system for refilling, emptying and/or recharging of an autonomous floor cleaner includes a docking station adapted to be coupled with a household plumbing infrastructure. The docking station can be provided on a household appliance, which may be a toilet, a dishwasher, or another appliance coupled with the plumbing infrastructure.

A floor mopping system (3) for an autonomous cleaning apparatus (1)65), comprising a mop roller assembly (5) including a mop roller (9) and a drive mechanism (19) for rotatably driving the mop roller about a longitudinal axis thereof, wherein the mop roller assembly is supported on a suspension assembly (63) comprising an adaptive suspension mechanism (65) for providing at least 3 degrees of movement for the mop roller assembly.
