You can see a list of actual pool cleaner options at bathpoolandspa.com. For now, I will just deal with the varieties of pool cleaners and not the actual models, which are ten-a-penny.
There are 3 types of cleaners, pressure and suction side cleaners link up with your pools filtration system to disregard waste, and robotic pool cleaners which are stand alone and capture dirt in an attached bag. These cleaners work automatically and only require you to switch them on.
With a suction and pressure side cleaner you will have to increase the speed of your pump and the filter while they are working.
