The housing may include top and bottom sides which extend generally between the front, rear, first and second sides.
The opening may be in the front and/or top and/or rear and/or bottom of the housing.
The opening and the cover may be positioned at or on the front side of the housing.
The first and/or second agitators may be positioned adjacent the cover.
The cover may be releasably connectable, e.g., removable from, the housing.
The cover may be pivotably movable, preferably downwardly, relative to the housing.
The cover may be slidably movable, preferably vertically, with respect to the housing.
The first and second agitators may be generally parallel.
The first and second agitators may be generally coaxial.
The first agitator may be inclined at an angle with respect to the second agitator.
The first axis of the first agitator may be inclined at an angle to the front and/or rear sides of the housing.
The second axis of the second agitator may be inclined at an angle to the front and/or rear sides of the housing.
The first agitator may be positioned on the first side of the housing.
The second agitator may be positioned on the second side of the housing.
The cleaner head may include a motor for driving the first and/or second agitator.

Referring tothere is shown a surface cleaning applianceaccording to an embodiment of the present disclosure. The surface cleaning applianceis, in particular a wet/dry vacuum cleaner, or multi-floor, cleaner. The surface cleaning applianceincludes a main bodyand a cleaner head. The surface cleaning appliancemay rest on the cleaner headin use and/or when in a stored position. The main bodymay be connected to the cleaner head. In particular the main bodymay be pivotably connected to the cleaner head. The connection between the main bodyand the cleaner headmay permit the main body to pivot in a fore-aft direction in which the cleaner is moved during use and to respective left and right sides of the cleaner headwhich are generally perpendicular, or perpendicular, to the fore-aft direction in which the cleaner is moved during use. In particular the pivotal connection may permit the main bodyto sit within a periphery of the cleaner head, i.e. within front, rear and first and second sides of the cleaner head(described in more detail below), so that a centre of gravity of the surface cleaning applianceis positioned within a footprint of the cleaner head. This permits the surface cleaning appliance to be stored in an upright position. To permit this pivotal connection an outlet pipe(shown in) is provided between the cleaner headand the main body. The outlet pipeis relatively flexible and ensures that the pivotal connection between the main bodyand cleanercan function. The outlet pipeis fluidly connected to a dirty air outlet of the cleaner head and to a dirt collection container, or recovery tank,. This is described in more detail below.
