Electric

These are self contained electric cleaners which are put into the pool when there is a need for cleaning. A transformer is plugged into a wall outlet and a long cord from the unit plugs into the transformer receiving low voltage power to operate the cleaner. This power operates two motors; a pump motor which draws debris into the unit's filter, and a drive motor which moves the unit around the pool.

The advantages to owning a robot cleaner include their self contained filter, which is easily cleaned. They also do quite well with their coverage. Some units are computer chip controlled, and some even have remote controls so you can steer the unit from a lounge chair! Being that they are the only cleaners not attached in any way to the pool's circulation system, they produce no resistance or back pressure on the filtering.
