  • Patent number: 7987543
    Abstract: In a working method for a cleaning device (2) that moves back and forth in a swimming pool (1), control thereof is such that the cleaning device (2) moves from a starting position at a low speed in a forward direction V in a first pass in a first cleaning path (4) until it runs up to a pool wall (3), wherein the distance D1 traversed along the first cleaning path is measured or determined. The cleaning device (2) is then guided to a second cleaning path (5) deviating from or offset relative to the first cleaning path (4) in a second pass, initially at a low speed, whereupon the cleaning device then moves in a backward direction along the second cleaning path (5) at a high speed until the distance Dz traversed is smaller than the distance D1 traversed in the previous pass by an amount A.

  • Patent number: 6473927
    Abstract: Cleaning device, especially for the cleaning of swimming pools, having a housing (1) and having at least one intake aperture (3) arranged on the base (2) of the housing through which, by means of a pump (4, 4′), a liquid to be cleaned can be conveyed into an inner chamber (5) at least partially enclosed by the housing (1) by a filter (6) which can be arranged in this inner chamber, in order to separate a contamination-exposed part (5′) from a clean part (5″) of the inner chamber, and through an outlet aperture (7), which is characterized in that the filter (6) lies sealingly on the bottom surface (8) of the inner chamber (5) and an underside (9) of a cover (10) which can be arranged over the inner chamber.

  • Patent number: 6309468
    Abstract: A cleaning device (2) which can be moved backwards and forwards in a swimming pool (1) has a drive mechanism which can be switched to forward or backward travel and has one motor for a left-hand-side and one for a right-hand-side part of the drive mechanism and a control apparatus for controlling the drive mechanism. The control apparatus has a speed regulation apparatus for each part of the drive mechanism and has means for differentially controlling the speed of the two motors. The cleaning device has means on both parts of the drive mechanism for measuring the distances (d1, d2) covered in forward and backward travel. The angles (R1, R2) of change of direction are calculated and differentially controlled by the control apparatus on the basis of the measured distances (d1, d2) covered and an offset width (v) of the respective travel tracks.

  • Patent number: 5256207
    Abstract: The invention relates to a process and apparatus for cleaning a swimming pool, where the apparatus or device, moves back and forth in the swimming pool, and where the device has driving gears or belts that can be switched to drive reverse or forward during operation. A contact rail is frontally positioned in the cleaning casing of the device, and a swich rail is positioned at the rear of the casing. Correction-dependent signals are obtained by the device striking an obstacle and these signals are supplied to a gear via a control mechanism. Upon obtaining such signals, the driving gear or belt slows down and remains still for so long until the other driving gear or belt which is still moving turns the cleaning device around and until the rear switch rail is activated. The signals resulting from the switch rail are used for switching the gear to reverse and for straightening out the cleaning device to a new position and prepare it to a forwards motion to continue its course along the swimming pool.

  • Patent number: 5245723
    Abstract: In a self-propelled cleaning apparatus, particularly for swimming pools, a cleaning apparatus drive (9) is integrated into a basic casing (1) and at least one cleaning brush (21) and a suction duct (29) are provided. By means of the said suction duct (29) the liquid to be cleaned is delivered by means of a pump (40) into a filter chamber (35). The filter chamber (35) extends over almost the entire top of the basic casing (1) and is covered by a casing cover (41).
