HARD-SURFACE VACUUM CLEANING SYSTEM HAVING AN EXTENSION DEVICE

摘要

The invention relates to a hard-surface vacuum cleaning system (10; 100; 120; 140; 160), comprising a portable hard-surface vacuum cleaner (12) for sucking up a liquid-air mixture from a hard surface, in particular from a window pane, having a suction nozzle (18), a suction unit (44) and a separation device (32) which is arranged in the flow path between the suction nozzle (18) and the suction unit (44) and which is connected to a dirty liquid tank (56), and having a handgrip (16) for gripping the hard-surface vacuum cleaner. In order to widen the area of use of the hard-surface vacuum cleaner (12) to areas which lie outside the immediate range of the user, the hard-surface vacuum cleaner system has an extension device (14; 104; 124; 144; 164), which is detachably connected to the hard-surface vacuum cleaner and has a handhold (96; 174) that can be gripped by the user.
