A surface cleaning apparatus, such as an extractor, has a separation stage comprising a separator and a separated liquid container in communication with a separated element outlet of the separator. When the surface cleaning apparatus is in a vertical orientation, the separated liquid container has a first portion underlying the separator, a second portion laterally spaced from the first portion and positioned below the separator and a third portion positioned above the second portion, and the third portion has a volume that is at least 80% of a volume of the first portion.

A lint cleaning assembly for a dryer appliance includes a vacuum aperture defined in a cabinet of the dryer appliance to allow a robotic vacuum cleaner to drive into the cabinet. A lint filter collects lint within a trap duct during operation and a lint collection duct extends from the trap duct to a vacuum docking station. The vacuum docking station is positioned within the cabinet for docking the robotic vacuum cleaner, fluidly coupling the robotic vacuum cleaner to the lint collection duct for lint removal, and/or charging the batteries of the robotic vacuum cleaner.

An automatic cleaning unit for AMHS includes a plurality of sensors disposed on OHT rails. The sensors are configured to define a cleaning zone and to detect a location of an OHT vehicle. The automatic cleaning unit further includes a vacuum generator and a top cleaning part installed over the OHT rails in the cleaning zone. The top cleaning part is coupled to the vacuum generator. The vacuum generator is turned on to perform a vacuum cleaning operation when the sensors detect the OHT vehicle entering the cleaning zone.

Disclosed are a robot cleaner, a refrigerator, a container transfer system, and a method of transferring and retrieving a container using the robot cleaner. The method of transferring a container include returning a robot cleaner to a position guide device installed at a refrigerator, mounting the robot cleaner on the position guide device, transferring, by the refrigerator, a container built in the refrigerator to mount the container on the robot cleaner, and moving the robot cleaner on which the container is mounted to a target position.

A surface cleaning apparatus has a surface cleaning head having a hard floor cleaning brush and a carpet cleaning brush, wherein the surface cleaning apparatus is operable in a hard floor cleaning configuration in which a liquid is delivered from at least one nozzle to the soft brush bar, and the surface cleaning apparatus is operable in a carpet cleaning configuration in which a liquid is delivered from at least one nozzle to the carpet cleaning brush.

A surface cleaning apparatus such as an extractor has a solid and liquid separation stage comprising a combined solid and liquid separator having a separated element outlet and, a solid and liquid collection chamber in communication with the separated element outlet. The solid and liquid separation chamber includes a screen provided therein, when the surface cleaning apparatus is in a floor cleaning orientation, the solid and liquid collection chamber has a lower region comprising a liquid collection region whereby, in operation, liquid passes through the screen and solid material collects on the screen.

A surface cleaning apparatus, such as an extractor, has a separated liquid reservoir wherein the separated liquid reservoir includes a liquid sequestering member.

An upright surface cleaning apparatus, such as an extractor, has an upright section moveably mounted to a surface cleaning head and a recline limiter system adapted to inhibit the upright section reclining to a positon at which recovered water enters the separator.

Ae multifunction vacuum cleaner includes a container body, which houses a suction unit of air flows from the outside; a filter of the air flows sucked from the outside; an accumulation tank of materials sucked from the outside and filtered by the filter; and a steam production unit and a system sending steam to the outside of the container body.
