A nozzle for a cleaner has a nozzle housing, and first and second rotation cleaning units arranged on a lower side of the nozzle housing and spaced apart from each other. Each of the first and second rotation cleaning units includes a rotation plate coupled to a mop. The nozzle includes a first driving device having a first driving motor to drive the first rotation cleaning unit. The nozzle also includes a second driving device having a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water tank mounted on the nozzle housing to store water. The nozzle housing includes driving unit covers arranged to surround each of the driving devices. At least one of the driving unit covers includes a first protruding surface, and a second protruding surface positioned higher than the first protruding surface.

In a method for operating a self-traveling floor treatment apparatus, a recording device of the floor treatment apparatus records a recording of an environment of the floor treatment apparatus, which concerns a time period, and the recording is displayed for a user of the floor treatment apparatus on a screen. In order to allow correction of error conditions, the recording is stored and, in case of a defined environmental event and/or apparatus condition of the floor treatment apparatus, a time-defined partial sequence is subsequently extracted from the stored recording and displayed on the screen.

A surface cleaning apparatus includes an upright body and 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 surface cleaning apparatus has a cyclone and a dirt collection chamber wherein the dirt collection chamber has a dirt collection chamber portion which is located axially spaced from the cyclone chamber and the dirt collection chamber portion has a transverse section in a plane transverse to the longitudinal axis of the cyclone that is annular.

An upright extractor has an upright section moveably mounted to a surface cleaning head. The upright section has a wand and hose assembly and a liquid separator. The liquid separator comprises a solid collection chamber that is separated from a liquid collection chamber by a porous divider. The upright extractor is operable in a floor cleaning mode in which the handle is a driving handle of the upright extractor. The upright extractor is also operable in an above floor cleaning mode in which the inlet end of the wand is disconnected from fluid flow communication with the surface cleaning head dirty fluid inlet and an above floor air flow path extends from the inlet end of the wand to the clean air outlet and the liquid separator and the suction motor are provided in the above floor cleaning air flow path.

A surface cleaning apparatus is provided with a base assembly, an upright assembly, and a fluid recovery system. The base assembly includes a base housing, a brush chamber, at least one brushroll in the brush chamber; and a removable brush housing. A portion of the brush chamber is removable with the brush housing.

A nozzle for a cleaner has a nozzle housing including a nozzle base and a nozzle cover coupled to an upper side of nozzle base, the nozzle cover including a bottom wall recessed towards the nozzle base, a flow path forming portion positioned between the nozzle base and the nozzle cover, a connection tube positioned at a rear side of nozzle housing, a water tank positioned on the nozzle cover and a plurality of rotation cleaning units arranged on a bottom side of the nozzle base and spaced apart from each other in a lateral direction, each the plurality of rotation cleaning units including a rotation plate configured to be coupled to a mop.

A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air containing dust can flow and a driving unit cover including a plurality of protruding surfaces, a first rotation cleaning unit and a second rotation cleaning unit disposed on a bottom side of the nozzle housing, each of the first rotation cleaning unit and the second rotation cleaning unit including a rotation plate designed to be coupled to a mop, rotation centers of the first rotation cleaning unit and the second rotation cleaning unit are eccentric with respect to a center of the driving unit cover, a driving device for driving the first rotation cleaning unit and the second rotation cleaning unit; and a water tank provided on the nozzle housing and for storing water to be supplied to the mops.
