摘要： A robotic cleaning device, along with associated systems and methods of using the same, is described. The device may include a body portion that may define a top surface, a bottom surface, and a continuous sidewall surface. An example device may further include a drive system that propels the robotic device. An example device may further include two or more bottom brushes. An example device may further include a continuous opening that translates around the sidewall surface. An example device may further include a pair of sidewall brushes that may oscillate along the opening.

摘要： A pole for a swimming pool comprises a tool for swimming pool maintenance located at one end of the pole and a device for preventing the pole from sliding into the swimming pool. The device comprises a face that surrounds the pole generally perpendicular to the pole and a baffle that extends from the outside edge of the face generally parallel to the pole. The device prevents the pole from sliding into the swimming pole by a user placing the baffle on a surface at the edge of the swimming pool.
