摘要

Device (1) for cleaning the surfaces of objects and buildings comprises two lateral longitudinal tie-bars (5) spaced from the surface (2) to be cleaned and having linear guiding units (6) on which are fixed cross tie-bars (7) having further linear guiding units (8). A working support (7a) is guided on the cross tie-bars and their linear guiding units. Preferred Features: The longitudinal tie-bars are telescopic and are formed as ladders (18) which can move against each other using an electric motor. The linear guiding units of the longitudinal tie-bars are arranged on the innermost ladder (18a).
