Query: Not What You'd Expect

This sweeper can only pick up a little bit of dust and dirt at a time. The area containing the dirt is no bigger than a deck of cards. That means that if you have pet hair, you can only make a swipe or two before it is full and you need to empty it.It may just be me, but I expected this to have some suction or something. It does not. The battery powers the brushes and that is all.I didn't feel that it picked up well and I was just using it to run over our hard wood floors each night.I ended up returning the item. I thought it was junk.
