Submersible pool cleaner with integral rechargeable battery
First Claim
1. A self-propelled, submersible pool cleaner comprising:
- a) an integral sealed rechargeable battery;
b) a sealed water pump motor electrically connected to said battery, said motor having a shaft on which is mounted an impeller; and
c) a waterproof sealed first portion of an inductive charging assembly electrically connected to said battery, said first portion of the inductive charging assembly being permanently affixed to said pool cleaner, said first portion of the inductive charging assembly having an aperture for receiving a sealed second portion of the inductive charging assembly adapted to be connected to an external power supply, wherein the aperture in the first portion of the inductive charging assembly receives the second portion in mating relation for recharging said battery while maintaining the first and second portions sealed.

Abstract
A submersible robotic pool cleaner is provided with an integral sealed rechargeable battery and an inductive charging assembly, a first portion of which is mounted in the pool cleaner housing and during the charging, receives a second separate portion that is connected by a cable to a conventional power source. The pump motor drive shaft is treated with a specialized anti-friction lubricant composition to minimize frictional energy losses where the shaft contacts the seal(s) and any shaft bearing(s), to maximize efficiency and minimize the power consumption of the pump motor assembly and permit the pool cleaner to completely traverse the surfaces to be cleaned within the fully-charged power capacity of the battery.
