A robotic cleaner may include a body, an agitator chamber within the body, an agitator disposed within the agitator chamber, a dust cup removably coupled to the body, the dust cup including a debris inlet, the debris inlet fluidly coupling the dust cup to the agitator chamber, and a shutter configured to transition between a cleaning position and an evacuation position in response to rotational movement of the agitator.

A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.

A vacuum cleaner includes a housing having a suction nozzle opening, a source of suction in fluid communication with the suction nozzle opening for generating a working air stream through the housing, and a multiply-adjustable debris collecting blade coupled along the rear of the suction nozzle opening for collecting debris.

A surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the liquid collection container and the solid collection chamber are emptyable concurrently.

A suction head of a vacuum cleaner including a housing having a suction port, a drum brush rotatably installed in the housing, a foreign substance removal pad provided on an inner surface of the housing to remove foreign substances wound on the drum brush by friction, and an anti-slip pad provided on the drum brush to prevent the foreign substances from slipping upon experiencing the friction with the foreign substance removal pad.

A robotic cleaner may include a body, an agitator chamber within the body, an agitator disposed within the agitator chamber, a dust cup removably coupled to the body, the dust cup including a debris inlet, the debris inlet fluidly coupling the dust cup to the agitator chamber, and a shutter configured to transition between a cleaning position and an evacuation position in response to rotational movement of the agitator.

A surface cleaning apparatus, such as an extractor, has a liquid delivery system operable to alternately deliver a carpet cleaning solution and a hard floor cleaning solution.

A surface cleaning apparatus such as an extractor is operable in a floor cleaning mode which utilizes a floor cleaning fluid flow path. The surface cleaning apparatus is also operable in an above floor cleaning mode which utilizes a different above floor fluid flow path.

An upright surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the cyclone separator is positioned above and downstream from the first stage liquid separator when the upright section is in the storage position.
