Definitions

  • the invention relates to automatic pool cleaners, in particular, the invention relates to battery operated automatic pool cleaners and their method of operation.
  • Automatic pool cleaners are used for cleaning surfaces, including underwater surfaces in commercial and residential pools. Some automatic pool cleaners operate independently and are battery operated to allow for flexibility in cleaning options. Automatic pool cleaners in swimming pools require a pump unit to draw water through a filter unit that traps foreign objects -including dirt or debris, but allows water to pass through the filter unit back into the pool. Typically the pump unit consumes a significant portion of the power of an automatic pool cleaner.
  • Some automatic pool cleaners draw their power from onboard batteries. Typically, battery operated automatic pool cleaners require no external power cables. However, battery operated automatic pool cleaners may necessitate frequent charging due to the power consumed by the cleaning mechanisms, with the frequent charging depleting overall battery life. Further, battery life between charges is typically limited, limiting the amount of cleaning an automatic pool cleaner can do between charges.
