Abstract: A vacuum cleaner comprises a removable dust separator. The dust separator has an inlet duct and an outlet duct. The inlet duct is arranged for fluid connection to a dirt-air duct on the cleaner, and the outlet duct is arranged for fluid connection to a motor intake duct on the cleaner. In accordance with the invention, the inlet duct and outlet duct share a common wall which divides the open ends of the ducts, an inlet duct sealing member is provided for forming an air-seal between the inlet duct and the dirty-air duct, and an outlet duct sealing member is provided for forming an air seal between the outlet duct and the motor intake duct. Both seals are thus required to fail in order to short-circuit the two dirty-air duct and the motor intake duct, despite there being a common wall section between the inlet duct and the outlet ducts.

Abstract: A cleaner head for a vacuum cleaner has a dirty-air inlet provided in a main suction chamber of the cleaner head, an outlet duct extending from the main suction chamber for connection to a suction source, and a rotating brush bar housed inside the main suction chamber for agitating a floor surface contacted through the dirty-air inlet. The brush bar is driven by an air-cooled motor housed inside a hollow section of the brush bar, the motor having an air intake and an air exhaust fluidly connected to one another to form an air cooling path through the inside of the motor. The air intake is connected to a clean air inlet on the cleaner head and the air exhaust is fluidly connected to the outlet duct by an exhaust duct which bypasses the main suction chamber.

Abstract: A cleaner head for a vacuum cleaning appliance includes a housing which defines a suction chamber. The suction chamber has a suction inlet through which air enters the suction chamber, and a suction port through which air exits the suction chamber. The cleaner head includes a plurality of casters for supporting the cleaner head. Each caster is rotatable relative to the housing about a first axis which is perpendicular to the suction inlet. Each caster is also rotatable relative to the housing about a second axis perpendicular to the first axis.

Abstract: A cleaner head for a vacuum cleaner houses a hollow brush bar mounted for rotation about an axis. This brush bar is driven by a motor housed inside the hollow brush bar, the motor forming part of a drive assembly supported at one end of the cleaner head. The brush bar is arranged for removal from the cleaner head by sliding the brush bar along the axis and out through an opening at the opposite end of the cleaner head and the brush bar is rotatably supported in clearance around the drive assembly by a first bearing, which bearing engages the brush bar in a corresponding axial-sliding fit to allow said sliding removal of the brush bar.
