ABSTRACT:
A wallpaper removing steamer is disclosed that comprises a steam applicator assembly mounted on a base for dispensing steam on receipt thereof. Four suction cups are provided at each corner of the base and are adapted to secure the base to a wall papered surface, each suction cup being connected to a vacuum supply. The use of a vacuum supply enables suction cups of a less rigid construction to be employed than those which are mechanically operated. The use of more compliant cups can facilitate self-adjustment of the cups to an uneven wall surface. The cups can be of concertina form and can be provided with an annular, flexible closed-cell foam pad around their mouths to assist in sealing against an irregular surface.
