We have a bunch of Ryobi 18v cordless tools, so I bought a Ryobi Cordless Vac to use in our travel trailer. My wife liked how well it worked so it is used in the house as well as the trailer. The big corded vac only makes occasional appearances. It cleans up hair from our 150lb Saint Bernard pretty well.
