摘要： 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.

摘要： A telescopic extension device for cleaning systems comprising at least one first external tubular assembly and one second internal tubular assembly slidingly coupled with each other so as to vary its own extension. Each tubular assembly comprises two channels for the passage of the fluid streams produced by a vacuum cleaner also capable of producing steam. In a preferred embodiment, the duct featuring the greater diameter is used to suck the air and the particles of dirt whereas the other duct makes steam flow outward.

摘要： A liquid extraction cleaning device comprises a vacuum pump, a liquid pump, a cleaning solution tank, a recovery tank, first and second spray nozzles, a spray selection switch, a vacuum inlet port, an agitator assembly, and a handle. The spray selection switch controls whether liquid is expelled from the second spray nozzle when liquid is expelled from the first spray nozzle. The agitator assembly comprises first and second agitators. The first agitator is configured to rotate. The second agitator is configured to reciprocate. The handle is pivotally connected to the rest of the liquid extraction cleaning device and is lockable in several pivotal orientations. The handle can also be pivoted forward from a rearwardly extending direction to an extent that it extends forward horizontally.
