Check out HSN. Theirs usually comes with extra accessories, like an extra electronic wall and the charger that it automatically goes to when finished. Bed Bath and Beyond with a 20 percent coupon might be a good price too. I had one quite a few years ago when we first moved into our new house that broke and never replaced it. I think they make them better now, but I have hardwood floors in just about the entire house and it was good until I started placing large area rugs in the rooms and more furniture and it was always just getting stuck in places. I think they would be fine for a small house with minimal furniture, but I have found a small cordless vac meets my needs to pick up the daily dog hair in the nooks and crannies, and then I use my big Dyson to to the rugs.
