The improved vacuum cleaner is a recirculating type vacuum cleaner with a suction mechanism, air retrieving passageway, and dirt collecting member, that has an detachable nozzle formed as an elongated hollow hose that is attached between the exhaust port on the surface of the vacuum body and an inlet on the vacuum head. The nozzle is adapted to push air downward onto the surface to be vacuumed to dislodge dirt and particles in the surface where the air and dirt into air retrieving opening on the vacuum head.

An air purification device includes a movement portion configured to move the air purification device to a target region; and a purification portion configured to purify air in the target region to improve air quality of the target region.

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.

An autonomous cleaning robot includes a drive operable to move the autonomous cleaning robot across a floor surface; a cleaning assembly configured to clean the floor surface; a receiver configured to receive an indication of cat activity in a cat box; and a controller configured to navigate the autonomous cleaning robot to the cat box to execute a cleaning mission in response to the received indication of cat activity.

A vacuum cleaner having a body supported on frame members that join to form a saddle beneath the body and are connected to a central member that extends downwardly to a nozzle assembly. The central member is tubular and communicates with a passage in one of the upper frame members to form a flow path from the nozzle assembly. An articulated neck interconnects the central member and the nozzle assembly to transmit front-to-back and rotational motions applied via a handle above the body. A detachable hose forms a flow path from the tubular frame members to a bag housing in an upper part of the body. A motor housing below the bag housing includes a diverter that directs air and noise from the vacuum blower against a closed rearward wall and out a front vent directed away from the user. An ozone generator introduces ozone/ions into the discharge air.

Disclosed is a dust collector using fan heat, comprising a bottom shell (10) and an upper cover (50), wherein a rear end (12) of the bottom shell (10) is provided with an air outlet (122) and a fan assembly (30), the upper cover (50) covers and is connected to the bottom shell (10), air flow from the fan assembly (30) is discharged via the air outlet (122), and the fan assembly (30) is provided with a fan (33) and a stator (331); and the rear end (12) is provided with a lower frame edge (121), the fan assembly (30) and the air outlet (122) are enclosed to form a closed air flow channel (35), and a heat collector (40) is provided on the stator (331) in the air flow channel (35), and can rapidly collect heat and warm the air flow to form hot air flow. Also disclosed is a dust collector having an ironing function, which uses hot air flow to heat an ironing board (60) and then performs ironing and sterilization, so that the dust collector also implements recycling of energy resources while achieving the dust collection effect so as to perform effective sterilization and ironing.
