FIELD: household equipment, in particular, technique for vacuum cleaning of dusted surfaces. ^ SUBSTANCE: wireless vacuum cleaner has casing, dust and air pipe connected to casing, and platform equipped with supporting members and built-in branch pipe. Dust and air pipe is made in the form of extension piece mounted within branch pipe so that it may change its axial position and be disconnected, and flexible hose disposed between casing and extension piece. Supporting members are formed as self-adjusting rotary rollers. ^ EFFECT: wider operational capabilities of wireless vacuum cleaner and reduced intensity of labor consumed for cleaning of vast area surfaces and also heavily blocked up parts of surfaces with narrow passageways and labyrinth-like abrupt turns. ^ 3 cl, 2 dwg |
