A cleaning appliance of the cylinder type comprises a separating apparatus for separating dirt from a dirt-bearing fluid flow, and a floor-engaging rolling assembly. The separating apparatus comprises a first cyclonic separation unit having a low efficiency cyclone and a second cyclonic separation unit having a plurality of second cyclones. The rolling assembly comprises a main body and a pair of floor-engaging wheels. The main body comprises a recess in which the separating apparatus is received such that when the cleaning appliance is viewed from either side at least one fifth of the width of the low efficiency cyclone is hidden from view by a portion of the rolling assembly at the point of maximum depth of the recess.

A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. The hose includes a hose plug of cuff connected with a distal end of the hose. The hose plug includes an annular channel and a cam to move a pin or button on the valve. The hose plug or cuff may also include a first seal and a second seal.

A vacuum nozzle system has a vacuum nozzle with an inlet opening for engaging a surface to be vacuumed and an outlet opening for connection to a vacuum supply hose. The inlet opening is delimited by a circumferential end face. The nozzle defining a vacuum flow direction from the inlet opening to the outlet opening. A holder bracket has a holder for holding the nozzle. The holder is disposed downstream of the end face in a vacuum flow in the vacuum flow direction when the nozzle is in a retained position on the holder bracket.

A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

A cleaner station includes: a housing; a dust collecting motor configured to generate a suction force for sucking dust in a dust bin of a cleaner; a dust collecting part disposed at an upper side in a gravitational direction of the dust collecting motor; a coupling part including a coupling surface to which the cleaner is coupled; and a fixing unit configured to fix the cleaner when the cleaner is coupled to the coupling part, thereby allowing a user to seal the cleaner without applying a separate force.

A surface cleaning apparatus such as a vacuum cleaner includes a suction source, a recovery container, and a base assembly with at least one agitator within an agitator chamber. The recovery container can be coupled to a separator assembly configured to remove dirt and debris from working fluid through the vacuum cleaner. In addition, a brake assembly can be provided on the base assembly and be configured to contact at least one wheel of the base assembly.

A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

A vacuum cleaner includes a housing defining a longitudinal axis, an inlet defining an opening through which debris is provided into the housing, a cyclone chamber configured to receive the debris from the inlet, the cyclone chamber being annular, defining a central opening and a debris opening positioned radially outward of the central opening. The vacuum cleaner includes a dust collection chamber configured to receive the debris from the cyclone chamber via the debris opening, a suction motor assembly positioned within the housing and configured to generate an airflow through the inlet and the cyclone chamber, and an airflow passage extending from the central opening of the cyclone chamber to the suction motor assembly. The suction motor assembly draws the airflow from the cyclone chamber through the airflow passage. The airflow passage extends downward from the cyclone chamber and into an interior of the dust collection chamber.

A backpack supported power tool is provided. The power tool includes a frame including a back plate having an upper end and a lower end and defining a back plate plane; and a tool body coupled to the frame by a coupling apparatus. The coupling apparatus includes a coupler configured to enable movement of the tool body in a lateral side to side direction relative to the back plate plane. The tool body includes a user interface configured to be gripped by a user to support and direct movement of the tool body.
