Could you tell me something about pool robots?

I have a pool robot. It is self contained vacuum, pump and has filter system which removes leaves, hair, sand, silt, pollen, algae and even the bacteria (as small as two microns) as it deep the cleans surfaces and the pool water. Improves the pool water chemical mix and the temperature circulation and then reduces the total run time of the pool's filtration system. Does not require even the removal and dumping of pool water and the chemicals in the environment. Verro operates on about the 24 volts and it also works independently of the pool's filtration system. In addition, Verro does not even require the removal and then dumping of the pool water and the chemicals into the environment, so it reduces waste. I love this type of pool robots. This is awesome. I hope you liked my answer.
