A vacuum cleaner with a reduced frictional force between a vacuum base and a cleaning medium is described. The vacuum has a handle, yoke, body, and base. A handle and yoke distinct from, and behind, the base provides a moment arm anterior to the base when a force is applied. The handle and yoke assembly reduce the friction between the cleaning surface and the vacuum, allowing for larger motor and debris capturing capabilities, with easier handling and maneuverability resulting in advanced and superior cleaning capabilities.

A vacuum cleaner, movable over a surface, includes a suction source, a suction port, and a dustpan attachment removably coupled to the suction port. The dustpan attachment includes a housing, a vacuum port, and a recess defined within the housing. The housing includes a top wall and a plurality of walls extending from the top wall to a bottom edge configured to contact the surface. The vacuum port extends through at least the top wall or one of the plurality of walls and is coupled to the suction port. When the bottom edge contacts the surface, the recess cooperates with the surface to form a suction channel having a suction inlet formed in a front of the housing and in communication with the vacuum port. The housing defines first and second ends. The bottom edge includes a sealing material that contacts the surface continuously between the first and second ends.

A vacuum accessory tool is provided. The vacuum accessory tool includes a body, a turbine, a generator, and a light source. The body defines a suction inlet, a fluid outlet, and a fluid flow path extending from the suction inlet to the fluid outlet. The turbine is rotatably mounted to the body in fluid communication with the fluid flow path to be rotated by fluid passing through the fluid flow path. The generator is coupled to the turbine such that rotation of the turbine rotates the shaft to generate power. The light source is electrically coupled to the generator and configured to receive the power generated by the generator to power the light source by the fluid passing through the fluid flow path.

The cleaner includes a main body having an opening, a suction motor accommodated in the main body and configured to generate suction force, an opening cover separably coupled to the main body and configured to cover the opening, and a filter mechanism accommodated in the main body through the opening and configured to filter foreign substances of air discharged by the suction motor. When the opening cover is separated from the main body, at least a portion of the filter mechanism protrudes to the outside of the main body through the opening. While the opening cover is coupled to the main body, at least a portion of the filter mechanism protruding to the outside of the main body is pressed by the opening cover so as to be accommodated in the main body.

There is provided a robot cleaner having an improved dust-collecting capability and an improved suction force and capable of being manufactured in a small size. The robot cleaner includes a main body comprising a fan motor and having a suction port provided in one side thereof; a plurality of cyclone units configured to separate foreign substances in air suctioned through the suction port; and a plurality of suction flow paths connecting the plurality of cyclone units and the suction port.

A surface cleaning apparatus includes a surface cleaning head having a dirty air inlet and an upper section mount moveably coupled to the surface cleaning head. An upper portion is mounted to the upper section mount. The upper section comprises a wand. A portable surface cleaning unit is removably mounted to the upper portion. An air flow path extends from the dirty air inlet to a clean air outlet and includes an upstream portion comprising the wand and a flexible air flow conduit downstream of the wand. Each of the wand and the portable cleaning unit can be separately removable from the upper section mount.

A suction head for a vacuum cleaner or the like is described, said suction head comprising: a base plate with a base plate channel open towards a surface to be vacuumed, a suction channel in fluid communication with the base plate channel, main wheels for moving said suction head on the surface to be vacuumed, and a bracket for connecting said main wheels to said base plate, wherein said bracket is connected to said base plate in a rotatable manner so that said base plate is tiltable with respect to the main wheels.

An upright vacuum cleaner with one or more features, such as a top opening rigid container, a headlight, a replaceable power cord a motor housing suspended within the vacuum to reduce noise and/or vibration a clutch assembly with a RPM sensor, and/or one or more filter plates to improve airflow.
