I like mine just for the convenience that the options provide. I can choose to the 5 RPM exactly where I want to vac, skim, or let it ride full throttle for fast surface clearing after a storm. 99% of the time it is sipping electric which is also a huge plus. So I run it 24/7 without a care in the world. It never stops skimming and IMHO, the only way to go.
