The invention relates to a cleaner comprising an external shell or casing (1) forming a suction hood, and an upper suction mouth (2), said casing also being provided with drive means arranged on each side and equipped with independent motors and corresponding transmission mechanisms on each side, and cleaning rollers (51, 52, 53, 54). In addition, the cleaner comprises: sets of internal cleaning rollers (53, 54) disposed close to the centre of the hollow interior of the casing (1) and having a width that is approximately equal to the distance between the side elements (11) of said casing (1); sets of external cleaning rollers (51, 52) located close to the front and rear edges of the casing (1) of the cleaning device and having a total width that is slightly greater than the width of the casing; a resilient joint at the support for the external rollers; a pair of adhesion turbines, possibly a suction turbine; and auxiliary drive wheels on the internal cleaning rollers. The cleaner also comprises a flotation body (200) connected to the casing (1) and having a fixed and/or variable volume. The cleaner further comprises laterally mobile turbines. |
