摘要：An underwater cleaning apparatus having a carrier, a plurality of wheels forshifting the position of the carrier along a submerged surface, a plurality of rotarybrushes carried by the carrier and adapted to clean the submerged surface, and a sourceof power for rotating the rotary brushes. The apparatus further comprises flexiblepartition wall members for transmitting torque to the rotary brushes and formingreduced pressure chambers communicated with spaces formed by bristles of respectiverotary brushes. As the rotary brushes rotate, the rotary brushes and the partition wallmembers in combination serve to provide vacuum to produce a force to press the carrierthrough the wheels onto the submerged surface to be cleaned. In addition, each of therotary brushes are allowed to individually follow the configuration of the surface thanksto the flexibility of the partition wall members.
