We bought this product and loved it - for a few weeks. Then, it would only hold a charge for an hour, then a half hour, then a few minutes. It seemed to have less and less power as well - it missed things that it would have picked up originally. Finally, it died. For the price, we got a few weeks of good sweeping, but what a waste of money.I contacted the company to complain, and they never responded. Buyer beware!
