Abstract
A device for cleaning the sidewalls of a swimming pool at the waterline region is self-propelled by water jets which also urge the device against the pool sidewall. The device includes brushes which brush against and clean the sidewall of the swimming pool as the device advances through the water. Means are provided for squirting a cleaning agent against the tiles. In one embodiment, means also are provided for collecting debris and dirt loosened by the brushes.
Claims33
A device for cleaning the sidewall of a swimming pool in the region of the waterline comprising:
- cleaning means for removing dirt from the waterline region of the sidewall of the pool, said waterline region including at least a portion of the sidewall which is above the waterline;
- flotation means for providing sufficient positive buoyancy to maintain said cleaning means at said waterline region of the pool;
- propulsion means for advancing the cleaning means horizontally along the water surface and along the sidewall of the pool at the waterline, thereby to clean the sidewall at said waterline region;
- said cleaning means further comprising scrubbing means adapted to engage the pool sidewall in wiping contact and to clean the pool sidewall in response to advancement of the device along the sidewall.

5 more elements
A device for cleaning the sidewall of a swimming pool in the region of the waterline comprising:
- A. A leading portion comprising:
- 1. a brush means for brushing the side walls of a pool vessel, thereby facilitating removal of dirt from said side walls;
- 2. fluid inlet means to be connected to a pressurized flow of water;
- 3. at least one jet outlet means in communication with said inlet means, said jet outlet means accommodating the outward flow of said pressurized flow of water thereby propelling said pool cleaner in the opposite direction of said outward flow of water;
- and
- 4. floatation means providing sufficient buoyancy to maintain said leading portion at the waterline when in use;
- B. A trailing portion comprising:
- 1. filtration means for filtering dirt removed by said brush means from said side walls;
- 2. fluid inlet means to be connected to a pressurized flow of water;
- 3. at least one jet outlet means in communication with said inlet means, said jet outlet means accommodating the outward flow of pressurized flow of water, thereby propelling said pool cleaner in the opposite direction of said outward flow of water;
- 4. flotation means providing sufficient buoyancy to maintain said trailing portion at the waterline when in use;
- and
- 5. rolling means for facilitating travel of said trailing portion along the side walls of a pool vessel;
- and
- C. A flexible connecting means comprising at least one bendable water inlet tube, one end of said inlet tube being in communication with said inlet means of said inlet portion, the other end of said inlet tube being in communication with said trailing portion, said water inlet tube accommodating a pressurized flow of water from said trailing means to said leading means, said flexible connecting means allowing said pool cleaner to bend at an angle sufficient to allow said pool cleaner to follow the angles of the sidewalls of a pool.
12 more elements
A system for cleaning the sidewall of a swimming pool at the waterline region comprising:
- a cleaning element including cleaning means for removing dirt from the waterline region of the sidewall of the pool, said waterline region including at least a portion of the sidewall which is above the waterline;
- means for supporting the cleaning element for advancement along the sidewall of the swimming pool at the region of the water line, said supporting and advancement means comprising flotation means for providing sufficient positive buoyancy to maintain said cleaning means at said waterline region of the pool, and propulsion means for advancing the cleaning means horizontally along the water surface and along the sidewall of the pool at the waterline, thereby to clean the sidewall at said waterline region;
- said pool having at least one skimmer opening in the sidewall of the pool at the region of the waterline;
- and
- means located at the skimmer opening to facilitate advancement of the cleaning element past the skimmer opening, said means being constructed and arranged to dislodge dirt particles from the cleaning means in response to advancement of the cleaning means past the skimmer opening.
