The EOS Automatic Pool Cover Winder works with your existing reels without any modifications. It features a "built-in" charger for the 12 volt battery and does not require a wall mounted charger that requires installation or wiring. The EOS includes a hand-held wireless remote for one person operation. The remote control makes it easier to adjust your covers during the storing process. The EOS is proudly made in the USA and is constructed of Solid Stainless Steel. It also comes completely assembled so it is ready to use right out of the box.
