A sweeping mechanism comprises an air duct suction opening (12) formed in the bottom (11) of a shell (1) and at least two sweeping brushes (15) which are independently arranged on the bottom (11) of the shell (1) and are separated from the air duct suction opening (12), and each of the at least two sweeping brushes (15) is driven to move back and forth integrally close to and far away from the air duct suction opening (12). The invention further provides a sweeping robot. The sweeping mechanism and the sweeping robot can effectively solve the problems of dust suction blockage and the like caused by winding due to the fact that the rolling main brush (108) is arranged in the air suction opening (107), and the dust suction efficiency and effect are effectively improved.

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.

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 vacuum cleaner includes an upright handle assembly, a foot assembly adapted to be moved along a surface to be cleaned and having a suction nozzle, a multi-axis joint swivelably mounting the upright handle assembly to the foot assembly and defining a first axis about which the upright handle assembly twists relative to the foot assembly and a second axis about which the upright handle assembly pivot relative to the foot assembly, and a detachable vacuum module supported on the upright handle assembly by the module platform.

Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. A cleaning head is coupled to a body of the vacuum cleaner via one or more suspension elements that comply to horizontal oscillations of the cleaning head imparted by an offset bearing of a vertical gear drive driven by a motor mounted to the body. A vacuum source draws air in from a suction nozzle at a forward underside portion of the cleaning head adjacent to a cleaning pad, and the air travels through an air filter disposed between the vacuum source and the collection chamber. In some embodiments, the air filter comprises one or more pleats adjacent to the vacuum source.

A cleaning robot for lifting dust and with multi-directional suction ports comprises a cleaning robot main body, at least one dust lifting device and at least one dust suction port disposed at a bottom of the cleaning robot main body, and the dust suction port is disposed around the dust lifting device. During traveling process of the cleaning robot main body of the cleaning robot for lifting dust and with multi-directional suction ports provided by the present invention, dust deposited on a bottom of fluff of a carpet is lifted by the dust lifting device by pushing, beating or blowing, and then the lifted dust is sucked into a dust collecting box disposed in the cleaning robot main body by the dust suction port to achieve an object of effectively cleaning the carpet.

A suction nozzle, and a vacuum cleaner, and a robot cleaner includes a housing having a suction port formed on a bottom surface thereof and a suction flow path formed on an inside thereof to communicate with the suction port, and a vibration cleaning unit arranged on the suction flow path to pass therethrough air including pollutants that flows in through the suction port, wherein the vibration cleaning unit includes a vibration source, a vibration transfer frame configured to accommodate the vibration source, and a vibration bar configured to receive vibration transferred from the vibration transfer frame to resonate.

Oscillating mechanisms with side brushes are presented including: a base assembly, the base assembly including, a base plate, a rotating axle extending perpendicularly from the base plate, at least one arm coupled with the rotating axle, a slot along a path of the at least one arm, and a first anchor positioned along a proximal end of the slot; and a brush assembly slidingly coupled with the base assembly, the brush assembly including, a hub slidingly coupled with the base plate along the slot, a side brush coupled with the hub, the side brush extending outwardly from the base assembly, a second anchor positioned along the hub, and a return spring coupled with the first anchor and the second anchor. In some embodiments, mechanisms further include: at least two arms coupled with the rotating axle, the at least two arms positioned at least 90 degrees apart from each other.

A cleaning head for a floor cleaner including a brushroll assembly configured to clean a surface to be cleaned and reduce brushroll maintenance, such as removing hair and debris wrapped around the brushroll assembly and removing debris from a bearing of the brushroll assembly. The brushroll assembly may comprise agitator members to assist in cleaning and maintenance.

A handheld air purifier may include a suction body provided with a fan to suction air and a filter to filter foreign matter from the sucked air, a handle extending from the suction body, and an agitator provided in the suction body to loosen or scatter dust from a garment. The handheld air purifier may be configured to be attached to and detached from a main air purifier, and the main air purifier may suction dust off the handheld air purifier and sterilize the handheld air purifier when the handheld air purifier is mounted on the main air purifier. The agitator of the handheld air purifier may have a striking member exposed through a lower surface of the suction body, and may move out of and into the suction body to strike the garment so that the dust may be loosened and suctioned into the suction body and filtered by the filter.
