Abstract
On floor cleaning machines, and on vacuum cleaners in particular, there is a protective bumper to provide protection for the machine against impacts and to protect furniture and other objects. The bumper extends along at least a portion of a side wall in the circumferential direction of the protective bumper. The protective bumper is provided with a supporting body which is made of an elastic material or an elastically compressible material, and is provided in the vicinity of its dimension, or side, facing away from the side wall with a cover which is made of a flexible material. The protective bumper provides a large exhaust surface area, which large exhaust surface area is used for the discharge of the exhaust air. As a result of the exhaust of the air over a large area, the invention achieves both a good reduction of acoustical emissions and a good filtering action.
