Abstract
The invention disclosed herein relates to an apparatus for automatically cleaning surfaces submerged within a liquid, such as the walls and floors of swimming pools. The apparatus comprises two suction passages in suction communication with a cleaning head that is releasably engageable with the surface to be cleaned and means, such as a flapper valve, for automatically transferring the flow of liquid from one passage to the other. By this means, as the flow of liquid in a passage is halted, the kinetic energy of the liquid is transferred to the apparatus, causing it to be displaced along the surface. The apparatus thus migrates randomly across the surface, cleaning it.
Claims22
A cleaning apparatus for automatically cleaning a surface submerged in a liquid, the apparatus including a cleaning head having a peripheral region releasably engageable with the surface to be cleaned;
- two suction passages in suction communication with the head through communication openings therein;
- valve seats located at each of the communication openings;
- and a valve member that is automatically displaceable between and against the valve seats for automatically transferring liquid flow through the passages from the head alternately and repeatedly from one of the passages to the other.
A cleaning apparatus for automatically cleaning a surface submerged in a liquid, the apparatus including a cleaning head having a peripheral region releasably engageable with the surface to be cleaned and having a sealing flange of a flexible material which is rotatable about the cleaning head;
- two suction passages in suction communication with the head through communication openings therein;
- and means for automatically transferring liquid flow through the passages from the head alternately and repeatedly from one of the passages to the other.
A cleaning apparatus for automatically cleaning a surface submerged in a liquid, the apparatus including a cleaning head having a peripheral region releasably engageable with the surface to be cleaned;
- two suction passages in suction communication with the head through the communication openings therein;
- means for automatically transferring liquid flow through the passages from the head alternately and repeatedly from one of the passages to the other;
- and a displaceable ballast member which is automatically displaced due to the action of gravity away from the cleaning head when the peripheral region of the cleaning head is vertically oriented and the apparatus is tilted over a predetermined degree, and which automatically returns to its original position closer to the cleaning head when the peripheral region is horizontally oriented.
