A suction device (10) with a suction device housing (20), in which a suction turbine (11) for generating a suction flow (S) is arranged, the suction turbine (11) having a suction turbine inflow opening (11A), through which the suction flow (S) can flow into the suction turbine (11) and at least one suction turbine outflow opening (11B), through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for letting in the suction flow (S) and a dust collecting chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collecting chamber (21) is arranged between the dust collecting chamber (21) and a suction turbine inflow opening (11A) of the suction turbine (11), wherein the suction device (10) has a closure element (60) with a closure body (61) for closing the suction inlet (12), which closes the suction inlet (12) in a closure position (V) and is removed from the suction inlet (12) in a release position (FS). The suction device (10) has a supply receptacle (68) for receiving the closure body (61), when the closure body (61) reaches the release position (FS).

A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

A wet surface cleaner operable in an upright cleaning mode, an auxiliary cleaning mode, and a lift-off cleaning mode. The surface cleaner has a canister assembly that is coupled to a body in the upright cleaning mode and removed from the body in the auxiliary cleaning mode and the lift-off cleaning mode.

A vacuum assembly includes a vacuum portion having a vacuum source with an inlet and an outlet and a tank portion. A three-way inlet valve fluidly connects the inlet to the vacuum source with the tank portion when in a first position and fluidly connects the inlet to the vacuum source with an inlet to a surrounding environment when in a second position. A three-way outlet valve fluidly connects the outlet of the vacuum source with an outlet to the surrounding environment when in a first position and the outlet of the vacuum source with the tank portion when in a second position.

A system has a floor processing device, a memory device and at least one accessory device for detachable connection with the floor processing device. The floor processing device has an acquisition device for acquiring the type of accessory device currently connected with the floor processing device, a user interface for receiving an operating specification for an operating parameter from a user, and a controller for controlling an operating activity according to the set operating parameter. The controller stores the operating parameter used last for a first operating activity together with information about the type of accessory device in the memory device and, after the accessory device has been disconnected from the floor processing device and then reconnected with the floor processing device, to access the stored operating parameter, and reset this operating parameter for a second operating activity to be performed chronologically after the first operating activity.

An extraction head for a cleaning machine is disclosed for traveling along a cleaning path on a variable-height floor. The extraction head comprises a body including a floor-facing surface and an extraction aperture disposed in the floor-facing surface. The extraction head comprises a vacuum outlet in fluid communication with the extraction aperture. The extraction head comprises an adjustable-height brush positioned in front of the extraction head body along the cleaning path. The adjustable-height brush is configured to translocate upwardly and downwardly as the extraction head moves along the cleaning path on the variable-height floor. The adjustable-height brush may comprise a proximal end and a distal end opposite the proximal end. The proximal and distal ends may be configured to translocate upwardly and downwardly relative to each other as the extraction head moves along the cleaning path on the variable-height floor.

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.

Cleaning equipment includesa water divider structure comprisinga pressuresource connected to a water supply tank, a water divider provided with a first distribution channel and a second distribution channel, wherein the first and second distribution channels both are connected with the pressuresource, anda first unidirectional valve connecting between the pressuresource and the water divider, wherein the first unidirectional valve connects through the pressuresource and the water divider under pressure formed when the pressuresource is activated. When there is residual water in the pipeline between the first unidirectional valve and the water divider structure, the first unidirectionalvalve can prevent the water in the water supply tank from being transported downstream. At this time, there is water in the pipeline downstream of the first unidirectionalvalve. One end is closed, and one end of the water divider structure is connected to the outside.

An apparatus for cleaning a surface of a glue roller of a labeling station that applies labels to containers includes a modular cleaning unit that one can insert into the apparatus to displace at least one segment of a multi-segment vacuum drum.
