Abstract: A suction pipe for a suction cleaner comprising an elongated pipe having at its lower end, in the in-use position, a coupling stud for a suction mouthpiece, and opposite this end, a flexible suction hose facing to one side relative to the elongated pipe, and wherein the suction pipe further has an upper operating handle arranged above the flexible suction hose in the in-use position. The upper operating handle in the in-use position of the suction pipe is arranged at a distance above the flexible suction hose that exceeds the length of the forearm of the operator, and the upper operating handle is so arranged that it allows it to be seized from that side of the suction pipe on which the flexible suction hose is arranged. This enables the operator to seize the upper operating handle with one hand and hold this upper operating handle at his own shoulder and to seize with his other hand further down on the suction pipe at the height of his hip whereby a completely new and ergonomically optimum work posture is obtained.

Abstract: A suction cleaner comprising a motor which operates a blower in such a manner that the blower blows a flow of air out into a motor chamber that delimits a volume which extends at least radially around the motor, and then out through outlet openings arranged in said motor chamber, and wherein the motor chamber is provided with a silencer element made of a silencing material, such as foamed plastics, said silencer element enclosing the motor radially and forming a silencing chamber around the same, and wherein the silencer element is provided with flow passages which substantially constitute the flow connection from said silencing chamber to the outflow openings in the motor chamber. The fact that the flow passages in the silencer element according to the invention extend axially along the motor in substantially the entire length thereof provides an optimum silencing effect.
