The invention relates to methods and devices for cleaning the hollow articles, and more particularly to devices for cleaning the shaft of the refuse chute in a multistory dwelling house. The goal of the invention is to improve the effectiveness of cleaning the cavity of the refuse chute's shaft in a multistory dwelling house. The device (fig. 5) consists of a drive motor (1) and a group of elastic scraping elements (2). The frame (3) of the drive motor (1) leans against the inner surface of the shaft (4) of a refuse chute through pressing contacts (5). The device is additionally supplied with a second drive motor (6), two planetary reducers and a second group of elastic scraping elements (7). In each of the reducers the axles (8, 9) of satellite gears (10, 11) on the one side are connected with a flange (12, 13) fastened on a frame (3, 14) of the corresponding drive motor (1, 6). According to the invention, the teeth of satellite gears (10, 11) are mashed with a sun gear (15, 16), fastened on the axle of motor (1, 6), and a crown gear (17, 18). The free ends of axles (19, 20) of the first and the second crown gears (17, 18) are coupled to each other through a half-coupling (23, 24). Each of the two mentioned groups of elements (2, 7) is fastened from the outer side on the frame of corresponding crown gear (17, 18), while the frame (14) of one of the drive motors ( 6) is coupled by a rope (25) to a lifting mechanism (26) installed on the upper level of the refuse chute's shaft (4).
