Query: Zero stars!! Company doesn't stand behind their product!

This could be a wonderful product but the rechargable battery is a very big problem. Like so many others who have written reviews, I have had problems with the battery not holding a charge in a sweeper that is less than six months old. Calling the company does absolutely no good so don't even bother.Both the rep and her supervisor told me that because they are not the manufacturer,they cannot offer any guarantee at all for the battery - BUT that they will replace it,if I pay for it. In other words, I have to buy a new one!! This is definitely a fly-by-night outfit so save your money by not buying a product that the company won't even stand behind.
