A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

A vacuum cleaner (1) comprising a container (2), a suction unit (60), an air channeling unit (25), operative between the container (2) and the suction unit (60), wherein the air channeling unit (25) comprises: a collector (26) having a suction mouth (27) at an intake side of the air channeling unit (25), a deflector (28) positioned at the intake side and radially extending at least over a central portion of the suction mouth (27), the collector (26) and the deflector (28) delimiting a suction channel (29) connecting the suction mouth (27) to an inlet port (22) of the suction unit (60).

A dust collector is provided, which includes a housing, a filter screen, and a spiral air director. The housing is provided with an air inlet, an air inlet channel, an air outlet channel, an air outlet, and a dust collection chamber. The dust collection chamber is in communication with the air inlet and the air outlet through the air inlet channel and the air outlet channel, respectively. The filter screen is disposed in the air outlet channel. The spiral air director is disposed in the air outlet channel and located on at least one side of an air inlet side and an air outlet side of the filter screen. Air flow flowing through the air outlet channel is directed by the spiral air director to form a swirling air flow.

Disclosed in the present invention is an electric tool, comprising: a housing, comprising a first opening; working equipment; a power apparatus, at least partially located in the housing and driving the working equipment; a surrounding structure, at least partially surrounding the power apparatus, the surrounding structure defining a second opening; and a blocking structure located between the first opening and the second opening.

A vacuum cleaner (1) comprising a container (2), a suction unit (60), an air channeling unit (25), operative between the container (2) and the suction unit (60), wherein the air channeling unit (25) comprises: a collector (26) having a suction mouth (27) at an intake side of the air channeling unit (25), a deflector (28) positioned at the intake side and radially extending at least over a central portion of the suction mouth (27), the collector (26) and the deflector (28) delimiting a suction channel (29) connecting the suction mouth (27) to an inlet port (22) of the suction unit (60).

A robot cleaner motor assembly including: a fan motor and a fan motor casing including an exhaust passage for guiding, to an exhaust port, air discharged from the fan motor, wherein the exhaust passage includes: a first exhaust passage guiding the air such that the air, discharged from a discharge port of the fan motor, moves to an upper or lower side of the fan motor; a second exhaust passage guiding, to a front end of the fan motor, the air discharged from the first exhaust passage; a third exhaust passage guiding the air such that the air, discharged from the second exhaust passage, moves to the lower or upper side of the fan motor along left and right sides of the fan motor; and a fourth exhaust passage guiding, to an exhaust port, the air having moved along the left and right sides of the third exhaust passage.

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.

An integrated tank has a debris-storage chamber, a water-storage chamber, and a muffler system. The muffler system is disposed proximate the water-storage chamber. The muffler system includes a bypass muffler and a discharge muffler.

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 vacuum cleaner that includes a suction motor and a filter assembly. The filter assembly surrounds at least part of the suction motor and has a frame to which a filter medium is attached. The filter medium is spaced from a wall of the frame such that an arcuate passageway is defined between the filter medium and the frame. A part of the air expelled by the suction motor enters a first end of the passageway and moves around the passageway in a clockwise direction. A further part of the air expelled by the suction motor enters a second end of the passageway and moves around the passageway in a counter-clockwise direction. Air within the passageway then passes through the filter medium.
