Provided is a vacuum cleaner including a cleaner body of which a center of gravity is disposed at a rear side further than a rotating center thereof; one pair of moving wheels provided at both side surfaces of the cleaner body and configured to rotatably support the cleaner body and also to be rotated for travelling; and a rear wheel unit provided at a bottom surface of the cleaner body and configured to elastically support the cleaner body at a rear of the pair of moving wheels, wherein the rear wheel unit includes a supporting part rotatably installed at the bottom surface of the cleaner body and rotated in a rotating direction of the cleaner body; an elastic portion configured to extend from one side of the supporting part and to be elastically deformed by being in contact with the bottom surface of the cleaner body when the supporting part is rotated; a rotating member shaft-coupled to the supporting part and installed to be rotatable in a direction intersecting with a rotating direction of the supporting part; and a rear wheel installed at the rotating member and rolled while being in contact with the ground.

A blower machine may include a blower unit configured to blow air; and an air passage pipe connected to an air duct of the blower unit. The air passage pipe may include an elbow pipe arranged on a proximal end side of the air passage pipe which is connected to the air duct; and a straight pipe extending straight and arranged on a distal end side of the air passage pipe than the elbow pipe. A first silencer pipe portion may be arranged at a proximal end portion of the straight pipe which is arranged on the distal end side of the air passage pipe than the elbow pipe, and the first silencer pipe portion may be provided with a sound absorbing material on an inner surface of the first silencer pipe.

A vibration isolation mount for a compressor that is formed of an elastomeric material and includes a sleeve, tapered studs or axial ribs spaced around the sleeve, and a lip seal extending around the sleeve. The mount is intended to be located between a compressor and a housing. The studs or ribs then deform to isolate the housing from radial vibration of the compressor, and the lip seal creates an annular seal between the housing and the compressor.

A mount for an electric motor that is formed of an elastomeric material and includes a sleeve around which ribs are formed. The ribs include first ribs and second ribs, and the first ribs project further from the sleeve and are more compliant than the second ribs.

Provided is a vacuum cleaner including a cleaner body; a moving wheel provided at each of both side surfaces of the cleaner body, rotated for travelling of the vacuum cleaner and configured to support the cleaner body to be rotatable in normal and reverse directions; a wheel motor assembly connected to the moving wheel and configured to rotate the moving wheel for the travelling of the vacuum cleaner; a main motor provided inside the cleaner body, located at a rear side further than a vertical extension line of a rotating center of the moving wheel and driven to suction dust; and a battery provided inside the cleaner body, located at the rear side further than the vertical extension line of the rotating center of the moving wheel and configured to provide electric power to the main motor and the wheel motor assembly, wherein a center of gravity of the cleaner body is located at a rear of the vertical extension line of the rotating center of the moving wheel due to an arrangement of the main motor and the battery.

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.

A floor cleaning apparatus (1) is provided including a cleaning assembly (500), a suction unit (10), an inlet channeling unit (20), and an outlet channeling unit (30). The suction unit (10) has a motor (11) and an impeller (12). The inlet channeling unit (20) is in fluid communication with at least one portion of the cleaning assembly (500). The outlet channeling unit (30) connects the suction unit (10) to an exhaust aperture (40). The outlet channeling unit (30) includes a first expansion chamber (31) and at least one intercepting wall (100). The first expansion chamber (31) faces the outlet side of the impeller (12).
