Abstract: A cleaner head for a cleaning appliance including a housing having a front side, a rear side, and first and second sides which extend between the front side and the rear side, the housing further including a floor facing surface which extends between the front side, rear side and first and second sides which, in use, faces a surface to be cleaned. A floor engaging device is connected to the floor facing surface of the housing and which extends laterally between the first and second sides of the housing, said floor engaging device including a first portion for absorbing liquid from a surface to be cleaned; and a second portion positioned closer to either a front side or a rear side of the housing, said second portion being relatively stiff compared to the first portion.

Abstract: A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front side and rear side, said housing further including a floor facing surface. The housing defines a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. A wiper device which extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. A floor engaging device extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. The floor engaging device includes an absorbent portion. The wiper device and the floor engaging device are positioned rearwardly of the dirty air inlet.

Abstract: A cleaner head for a cleaning appliance, including an agitator rotatable about an axis; a housing having a front side, a rear side and first and second sides which extend between the front side and rear side, said housing at least partially defining a chamber. The chamber at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. The chamber includes an opening for permitting access to and removal of the agitator from the chamber and a cover cooperatively associated with the housing for permitting access to the chamber through the opening. The cover is movable to an agitator access position to permit the agitator to be removed from the chamber through the opening in a direction substantially orthogonal to the axis of the agitator and in a direction which is substantially parallel to a plane of the surface to be cleaned.
