  • FIGS. 7A and 7B illustrate the internal module 22 in more detail. It is a self-contained unit and is attached to the frame 16 by a number of screws. When closed, it is preferably sealed to prevent ingress thereto of water.
  • the module 22 comprises an impeller 100 associated with a pump motor 104 , a shaft 110 associated with a drive motor 106 , a receptacle 102 , and a clasp 114 . Although a single module is shown, it should be appreciated that there may be several, for example separate modules for each motor, a transmission system, electronic controllers, etc.
  • the impeller 100 projects from the top side of the module 22 .
  • the pump motor 104 When driven by the pump motor 104 , it creates an upward pressure head which draws water into the robot 10 via the inlets, through the filter screen 11 , and out of the robot through the outlet opening 26 .
  • this action also provides suction which tends to bias the robot 10 toward the surface which is being cleaned. This is especially useful when the robot 10 is cleaning a sidewall.
  • the drive motor 106 comprises a stator housing 108 , in which the motion is produced, and the shaft 110 .
  • the shaft protrudes from a sidewall of the module 22 . It may be located non-concentrically to the main shaft of the motor (i.e., that which is located within the stator housing 108 ), and rotated by any mechanism, a plethora of which are known per se in the art.
  • the shaft 110 is of a generally circular cross-section. However, two sides 112 thereof are planar. This allows it to be received within a correspondingly shaped aperture in the timing belt pulley 48 , thereby transmitting full rotational force thereto without slippage.
  • the receptacle 102 is adapted for plugging therein the power cord 24 .
  • the receptacle is adapted to be waterproof, at least when the power cord is plugged in.
  • the clasp 114 is adapted to retain the power cord 24 in position, at least when it is plugged into the receptacle 102 .
  • the filter screen 11 is installed between the filter bag 13 and the internal frame 16 . It is affixed by one screw in each side to a screw hole 120 which is disposed in the internal frame 16 (see FIG. 2 ). As may be easily seen from the juxtaposition of the screw hole 120 to the seats 80 , the filter screen 11 is disposed between the internal module 22 and the filter bag 13 .
  • the internal module 16 comprises several auxiliary outlets 45 provided near the bottom of the sidewalls 28 .
  • Each auxiliary outlet 45 comprises four openings 47 and a center hole 49 adapted to retain a diaphragm (not shown) on the outside of outer surface of the sidewall.
  • the diaphragm is a disc of rubber with a central protrusion adapted to be retained by the center hole 49 .
  • the auxiliary outlets 45 provide an additional means for water to exit therefrom.
  • the diaphragms block water from entering the robot through the auxiliary outlets 45 .
  • the sidewalls 28 further comprise receiving members 46 which are internally threaded and disposed so that they receive screws adapted to secure the cover 12 .
  • the internal components of the robot 10 are arranged in such a way so that there is a weight imbalance about an axis of symmetry 96 (seen in FIG. 1B ) which is parallel to the track 20 . (It will be appreciated that the robot 10 moves in the direction of the track 20 , and thus of the axis of symmetry 96 . ) Due to this imbalance, the robot 10 , when moving, tends to curve away the side with the imbalance (i.e., if the left side of the robot 10 is heavier, the robot will tend to follow a trajectory which curves right). The imbalance is such that the heavier side of the robot 10 is attached to the float 19 .
  • the weight of the heavier side is offset somewhat, allowing the robot to sit on the floor of the swimming pool in a more balanced way when no suction is applied. Otherwise, the robot 10 , experiencing too great an imbalance, may be tilted to such a degree that even when suction is applied, only one track 20 rests on the pool floor.
  • a counter-weight is provided. This is typically done by increasing the suction of the robot 10 through the inlets.
  • the robot will tend to follow a curved trajectory.
  • the total weight of the robot was 0.6 kg.
  • the heavier side of the robot was 3times the weight of the lighter side, resulting in the heavier side being 0.45 kg, and the lighter side being 0.15 kg.
  • a counter weight was provided by increasing the suction to 1.1 kg.
