A part of an upper end portion of the tank body has a bent shape or a curved shape, and the rest part of the upper end portion of the tank body has a shape neither bending inward nor curved inward. The vacuum cleaner may further include a battery connection portion disposed at the head portion and a brushless motor disposed at the head portion. The vacuum cleaner is easy to assemble, portable, convenient in checking the battery level, waterproof and has a good performance of drainage, high efficiency in dust vacuuming, small size and compact structure, light weight, and improved service period.

A motor includes a motor housing, a rotating shaft assembly that includes a rotor mounted to the rotating shaft, an impeller connected to the rotating shaft, and an impeller cover that surrounds an outer circumference of the impeller. The impeller cover defines an air inlet. The motor further includes a stator that is located within the motor housing and that surrounds at least a portion of the rotor, a bearing mounted to the rotating shaft, and an elastic mesh having a plurality of pores. The elastic mesh is disposed between the motor housing and the bearing.

A suction nozzle includes a casing which defines a suction chamber, and an agitator rotatably mounted within the suction chamber. The agitator is supported in the suction chamber by a support member. A drive assembly arranged to rotate the agitator about an axis is mounted to the casing via the support member, and is mounted to the support member via a first soft mounting member. The support member is mounted to the casing via a second soft mounting member.

A reconfigurable upright vacuum cleaner has a portable surface cleaning unit removably mounted to an upper portion. The portable surface cleaning unit has a suction motor and an air treatment member. The air treatment member is removably mounted to the portable surface cleaning unit and secured in position by an air treatment member lock. The portable surface cleaning unit is secured in position by a portable surface cleaning unit lock. When the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the portable surface cleaning unit actuator is provided on an upper end of the portable surface cleaning unit and the air treatment member release actuator is provided on an upper end of the air treatment member.

A compact motor housing for housing a motor and a blower of a cleaning device and with integrated air outlet silencing. The motor housing encloses a flow passage between a flow inlet and outlet. The housing has a blower chamber fluidically connected to the flow inlet, and via first and second outlet openings also fluidically connected to at least two parallel, preferably similar, silencer ducts each being arranged in an area limited by an angle of less than 90, seen in a view parallel with the blower and motor axis. The silencer ducts each have at least one wall between the blower chamber and the external wall of the motor housing for causing at least one flow direction bend, so as to provide a noise attenuating effect. The areas occupied by the at least two silencer ducts are non-overlapping, seen in a view parallel with the blower and motor axis. With a circular blower chamber, a compact box shaped motor housing can be provided with corner volumes available for silencer ducts.

A vacuum cleaner of the present disclosure includes a cleaner body having a suction motor provided inside thereof and a handle provided outside thereof, and a suction nozzle connected to the cleaner body, wherein the suction nozzle includes a housing having at least part of a front portion opened, and a rotary cleaning unit disposed inside the housing, having at least part thereof exposed through the opening of the housing, and configured to clean a floor by a rotating operation, wherein the rotary cleaning unit includes a cylindrical nozzle body rotatably installed inside the housing, and fiber filaments and metal filaments disposed on an outer circumferential surface of the nozzle body.

Provided is a structure including a sound absorption section provided in an air flow path on an exhaust side of a fan, traversing a joint portion between a first main housing and a second main housing. The sound absorption section has a double wall structure including an inner wall facing the air flow path and an outer wall spaced outward from the inner wall. A sound absorption member is interposed in a sound absorption chamber between the inner wall and the outer wall of the sound absorption section. A communication hole communicating with the air flow path and the sound absorption chamber is formed in the inner wall of the sound absorption section at a position away from the joint portion.

An improved shop vacuum with wet/dry capability uses a vacuum tube that terminates in a space between the canister and the vacuum compartment such that the substance and content exiting the vacuum tube is not directly opposed the negative pressure source. This allows the substance to drain into the canister in a more controlled and less volatile condition, reducing splashing and entrainment of the substance. Moreover, a second exit for the vacuum has been added to the canister to improve the efficiency of the vacuum and the overall performance of the device.

An impeller is rotatable about a vertically extending central axis and includes a base portion extending radially outward as it extends downward, first blades circumferentially arrayed on the upper surface of the base portion and extending on one side in the circumferential direction as it extends upward, and second blades between the circumferential direction of the circumferentially adjacent first blades and extending on one side in the circumferential direction as it extends upward. The radial outer end of the second blade is on one side in the circumferential direction relative to the middle in the circumferential direction of the radial outer end of the circumferentially adjacent first blade.

A motor includes a motor housing, a rotating shaft assembly including a rotating shaft, a rotor, and a bearing in which the rotor and the bearing are mounted to the rotating shaft. The motor further includes a stator installed in the motor housing, the stator surrounding the rotor, a bracket mounted to the motor housing, and an elastic mesh that defines a plurality of pores, that is disposed between the bracket and the bearing, and that contacts at least one of the bracket or the bearing.
