ABSTRACT:
A protective "bumper cover" for vacuum cleaners, used by janitorial building personnel in commercial locations to prevent damage to conventional office furniture and walls, has a top and sides made of a tough moldable plastic material, for example, a polyurethane, which can be molded with a resilient inner layer and a tough outer "skin," the inner layer yielding in the case of impact with furniture, thus absorbing the collision energy, the outer "skin" resisting cutting and damage to the bumper cover due to such impact. Apertures in the cover provide access to adjustment screws and for inspection of the driving motor brushes. Straps molded integrally with the cover can be secured to the vacuum cleaner itself at various suitable anchoring points.
