Separated suction vents are provided for the crevice and bristled tools in order to provide maximum suction, and 360° rotatable wheels, lights, battery chamber, on/off switch, and battery recharge pin port are also provided. Also provided is a padded wrist support end cap and integrated swiveling end coupling nozzle, which can be detached for use as an independent brushless vacuum dusting device. An additional 360° manually rotating stabilizing wand, and independent accordion hose with ergonomic grip disk and handled vacuum attachment for use with aforesaid dusting attachment, are provided.

A cleaning accessory for a vacuum cleaner comprises a housing. At least one rotatable cleaning brush is rotatably mounted to the housing and configured to engage a surface to be cleaned. The at least one rotatable cleaning brush comprises at least one flexible cleaning element projecting outwards from a side of the housing. The at least one flexible cleaning element is arranged to rotate in a cleaning position and rotate in a disengaged position whereby the at last one flexible cleaning element engages the surface to be cleaned when rotating in the cleaning position and the at last one flexible cleaning element is remote from the surface to be cleaned when rotating in the disengaged position.

A nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.

A suction tool includes: a hollow cylindrical main pipe having: a rear end side connected to a vacuum cleaner main body; a front end portion in which a main suction port is formed; and a hollow cylindrical sub pipe having: a rear end side at which an inside of the hollow cylindrical sub pipe communicates with an inside of the main pipe; and a front end portion in which a sub suction port is formed. The sub pipe is movable between a retracted position in which the front end portion of the sub pipe is arranged so as to be retracted from the front end portion of the main pipe, and a use position in which the front end portion of the sub pipe is arranged so as to protrude from the front end portion of the main pipe along an axial direction of the main pipe.

This document describes a mobile cleaning robot that includes a chassis that supports a drive system, a debris collection volume; and a cleaning head formed to complete a bottom of the robot. The cleaning head includes a frame for affixing the cleaning head to the chassis, a monolithic housing having an interior cavity, a suspension linkage movably suspending the monolithic housing from the frame, the suspension linkage being configured to lift the monolithic housing, a diaphragm formed of a flexible material and mated to the monolithic housing, a rigid duct mated the frame to form a pneumatic path between the monolithic housing and the rigid duct through the diaphragm, and cleaning extractors disposed in the interior cavity of the monolithic housing.

A floor nozzle for a vacuum cleaner has a housing, and a base on the housing constructed for sliding in a working direction on a floor and formed with a downwardly open slot-shaped port delimited relative to the direction between a transversely extending front port edge and a transversely extending rear port edge. The base has, extending forward from the front port edge, a part-cylindrical and downwardly convex front surface with a front radius of curvature and centered on a transversely extending symmetry axis and, extending rearward from the rear port edge, a part-cylindrical and downwardly convex rear surface having a rear radius of curvature also centered on the symmetry axis. The housing is constructed for movement of air upward through the port.

A gear assembly includes an upper cover and a lower cover, a stator fixed to the lower cover, a rotor opposite to the stator and including a rotary shaft and magnet, a main gear fixed to the rotary shaft and rotating along with the rotary shaft, and a helical gear engaged with the main gear, the main gear and the helical gear being both received in the cover member, the upper cover including a boss portion with a recess receiving a tip of the rotary shaft. The rotor is axially movable and when the rotary shaft stops rotating, the tip of the rotary shaft is in the recess of the boss portion, and when the rotary shaft rotates, the helical gear applies a force on the main gear, and the tip of the rotary shaft is disengaged from the recess of the boss portion.

A cleaner head that includes an agitator in the form of a brush bar, the brush bar including a sealing material extending over the circumferential and axial extent of the brush bar, the sealing material including a tufted material, and a housing defining a chamber which at least partially surrounds the brush bar, a dirty air inlet in a lower part of the chamber and a front opening that exposes the brush bar at the front of the housing, the brush bar being supported for rotation with respect to the housing and arranged in the chamber, wherein a partition is arranged within the chamber between the brush bar and an outlet of the chamber, the partition extends transversely and divides the chamber into an agitating region and a settling chamber, and the partition includes a wall that extends tangentially to the brush bar and is inclined rearwardly.
