A dusting device to be rotatably connected to the bottom of a cleaning machine or vacuum cleaner includes a rotary disc and a dusting element. The rotary disc includes a base and a connecting portion below the base. The connecting portion extends outward from the periphery of the base and has a bottom surface forming a pressing plate. The dusting element is detachably assembled to the connecting portion of the rotary disc in order to be pressed by the pressing plate. The dusting element includes at least one cleaning layer for contact with a surface to be cleaned so as to carry out dusting and cleaning.

An outdoor cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via at least one nozzle. The at least one nozzle may be secured to a guard cover via grooves on an inner guard cover and an outer guard cover. The nozzle(s) enables the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.

A cleaner head for a surface cleaning apparatus, including: a first agitator rotatable about a first axis; a second agitator rotatable about a second axis; a housing movable along a surface to be cleaned; wherein the housing at least partially defines a chamber which at least partially surrounds the first and second agitators, wherein said chamber includes: a dirty air inlet; a dirty air outlet; and an opening for permitting access to and removal of the first and/or second agitators from the chamber; the cleaner head further including a cover cooperatively associated with the housing for permitting access to the chamber through the opening; wherein the cover is movable to an agitator access position to permit the first and/or second agitator to be removed from the chamber through the opening in a direction substantially orthogonal to the first and/or second axis of the respective first and/or second agitator and in a direction which is substantially parallel to a plane of the surface to be cleaned.

The present invention relates to the field of floor treatment machines for scrubbing, polishing, sanding or burnishing floors, and in particular machines in which one or more driven rotatable work heads (such as scrubbing brushes) are provided for agitating the floor surface. In one aspect there is provided a walk-behind floor treatment machine comprising: a base portion provided with and supported by at least one rotatable work head for treating the floor, a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion, drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means, wherein a lower region of the handle portion is pivotably connected to the wheel means via an articulated joint, the arrangement being such that the handle portion may be manipulated to act on the wheel means so as to yaw steer the wheel means about a yaw axis defined by the floor-engaging contact of the wheel means, the yawing of the wheel means causing the base portion to yaw in response to yaw steering. The wheel means may comprise a wheel, roller or ball, preferably a single wheel, roller or ball, disposed at a lower region of the handle portion. The wheel means preferably has a fixed transverse axis of rotation.
