The present invention discloses a reciprocating hair removal device for floor cleaning, comprising a roller brush, a first driving structure for rotating the a roller brush, a sliding rail parallel to the roller brush and a sliding block connected to the sliding rail; wherein the surface of the rolling brush is formed with two spiral grooves opposite to each other, the head ends of the two spiral grooves are connected, and the tail ends of them are connected to form a reciprocating spiral groove; wherein the sliding block is provided with a hair removal knife extending from one end to the reciprocating spiral groove; when the roller brush rotates, the hair removal knife reciprocates along the reciprocating spiral groove with respect to the roller brush. Therefore, the present invention can automatically remove foreign matter such as hair entangled on the roller brush during the brush cleaning operation.

A self-propelled cleaning device has a surface cleaning system for cleaning a surface to be cleaned. In order to also be able to clean an above-floor surface, the cleaning device also has an above-floor cleaning element for mechanically cleaning an above-floor surface offset in terms of height relative to the surface. The above-floor cleaning element can be rotated and/or pivoted around a rotational axis, and at least one partial cleaning area of the above-floor cleaning element has a difference in height of roughly 3 cm or more relative to a lowermost standing surface of the cleaning device by comparison to a usual orientation of the cleaning device for a cleaning operation.

An upright cleaner removes dust from a drum brush. The upright cleaner includes a case having a suction port, a drum brush rotatably provided in the case to sweep and guide foreign matter to the suction port, a dust removal unit provided in the case so that the dust removal unit is moved between a first position where one side of the dust removal unit contacts the drum brush and a second position where the side of the dust removal unit is separated from the drum brush, and a lever connected to the dust removal unit to actuate the dust removal unit.

A dust collection guide structure (10) arranged at the bottom (11) of a shell of a dust collection mechanism comprises an air duct suction opening (12) formed in the bottom (11) of the shell and at least one groove (13) formed in the surface of the bottom (11) of the shell. One end of each of the at least one groove (13) communicates with the air duct suction opening (12) to form a dust guide air duct for guiding dust into the air duct suction opening (12), and the other end is in smooth transition connection with the edge of the bottom (11) of the shell.

The present invention relates to a device in the form of a suction nozzle (10) for an urban or industrial aspirator (1), preferably self-propelled, comprising a rigid hose or tube (1000), said rigid hose or tube comprising gripping means (100, 200, 300, 400) that comprise a first gripping element (110, 210, 310, 410) in the form of a handle, a support element (120, 220, 320, 420) serving as a lever, and a second gripping element (130, 230, 330, 430) and optionally a base (101, 201, 301, 401).

A robot cleaner configured to elastically deform a brush part using contact force between bristles and a floor and then restoring the brush part to vibrate the bristles, thereby improving cleaning performance. The robot cleaner includes a case that moves on a floor, a brush shaft mounted to the case such that the brush shaft rotates by driving force from a drive unit, an elastic member fixed to the brush shaft, the elastic member made of an elastic material, and a brush part fixed to the elastic member, the brush part having bristles, wherein the brush part generates generate vibration during deformation and restoration of the elastic member when external force is applied. The elastic member deforms due to contact force between the bristles and the floor and is then restored, and the brush part vibrates during deformation and restoration of the elastic member.

A floor maintenance machine has an adjustable deck assembly. The floor maintenance machine includes a deck supporting a floor cleaning implement. A lifting arm extends away from a frame of the floor maintenance machine and is rotatably coupled to the deck. The lifting arm is rotatably actuatable to adjust a position of the deck relative to the frame. A support member is rotatably coupled to the frame and movably coupled to the deck. A stop member is supported by the deck and extends toward the lifting arm for selective engagement therewith. When the lifting arm is rotated relative to the frame to lift the deck, the stop member is driven into the lifting arm to limit relative rotation between the lifting arm and the deck beyond a set angle.

A cleaner head includes a housing part having an opening opened downwardly, a vibration generating part disposed to cover the opening, and having at least one inlet passing through an inhaling force to generate a vibration force, a brush part disposed under the vibration generating part, and receiving the vibration force to vibrate, and a vibration isolating part disposed around the housing part, and separating the vibration generated by the vibration generating part from the housing part.

A cleaner head 10 for a vacuum cleaner has a suction inlet 20 defined in the lower face of a housing 11 and a suction passageway 20A through the housing 11. A rotatable sealing element 40 is located at a front of the housing 11. The rotatable sealing element 40 has a rotational axis 41 which is parallel to the lower face of the cleaner head. An agitator 60 is positioned rewards of the rotatable sealing element 40. The suction passageway 20A is located between the agitator 60 and the rotatable sealing element 40.

This is my description of a new type of vacuum cleaner it uses forced positive pressure as well as negative vacuum pressure.

It uses both high and low velocity air pumped in to the suction nozzle.

Zero vortex is maintained by a variable air flow control module.

Because of the efficiency of this machine the noise levels are lower than any other vacuum.

The high velocity air is gained by means of a screw compressor driven by the motor.

The high velocity air is dispersed through ultrasonic jets at the pickup head.

The low velocity air pumped through venturi to the pickup head and maintains movement of particles at all times as there is zero vortex and air circulates continuously.
