Query: Really disappointing

I am really disappointed, the swivel sweeper is a great product whose major fault is this ridiculous battery. It cannot hold a charge for more than two minutes at the time. Although it may be a little inconvenient, it might actually be better to make a corded version.This is my third swivel sweeper so far and batteries has always been the issue. I think the battery will be the downfall of this product.
