Abstract
An automatic swimming pool cleaning system including a cleaner body intended to travel in a forward direction along a wall surface or on the water surface to substantially randomly traverse a swimming pool. The system includes a propulsion subsystem for producing a force to propel the body in a forward direction, a motion sensor for indicating when the velocity of the body, diminishes below a certain threshold rate, and a repositioning subsystem responsive to said motion sensor indication for producing a limited duration force to change the position of the body after which forward direction motion resumes.
Claims47
A swimming pool cleaner comprising:
- a cleaner body;
- a propulsion generator operable to produce a force for propelling said body in a forward direction;
- a motion sensor operable to indicate when said body fails to move at a rate exceeding a certain threshold;
- and
- repositioning means responsive to said motion sensor indication for producing a force for a limited duration to reposition said body;
- and whereby
- said propulsion generator after said limited duration causes said body to resume travel in said forward direction.
An automatic swimming pool cleaning system comprising:
- a cleaner body;
- a propulsion subsystem operable to produce a force for propelling said body in a forward direction;
- a motion sensor operable to indicate when said body velocity is below a certain threshold rate;
- and
- a repositioning subsystem responsive to said motion sensor indication for producing a force of limited duration to reposition said body, said propulsion subsystem operable after said limited duration to cause said body to resume travel in said forward direction.
An automatic swimming pool cleaning system including:
- a power source adapted to be mounted externally of a water pool contained by a containment wall;
- a cleaner body adapted for use in said water pool;
- a propulsion subsystem carried by said cleaner body for producing a force for propelling said body in a forward direction;
- an elongate conduit having a first end connected to said power source and a second end connected to said cleaner body for supplying power to said propulsion subsystem to propel said body in said forward direction to randomly traverse said pool;
- a motion sensor for indicating when the forward velocity of said body is below a threshold;
- and
- a repositioning subsystem actuatable in response to said motion sensor indication for producing a force of limited duration to reposition said body prior to said body resuming travel in said forward direction.
A method of operating a swimming pool cleaner body to enable it to randomly traverse a swimming pool comprising the steps of:
- propelling said cleaner body to move it in a forward direction;
- sensing the velocity of said body;
- responding to the velocity of said body diminishing below a certain threshold for generating a force to reposition said body;
- terminating said force after a short duration to permit said body to resume movement in said forward direction.
