This is my very 1st sweeper, and I wouldn't complain if I had only paid $9.99 or even $19.99 for this sweeper, because that's all it's worth. You have to, seriously, have to clean all 4 wheels and the rotating brushes after EVERY use; I see why they stop rolling after a few months.
I admit it picks up loose cat hair (woohoo!); however, I need something that can also pick up cat litter outside the litter box. This only picked up half the litter crumbs. Albeit, it will work for a quick pickier-upper if I have company suddenly on their way, but I will not replace it with another one, once it stops working.
It barely cleaned my flat throw rug by the back door. Plus, I have "floating" hard wood floors in my non-wet rooms; sadly, it could not suck up all the dirt in between the cracks where the boards have slipped apart and have spaces. This is something I hoped this machine could do.
Oh well, trial and error. I confess, I was happier with a heavy bulky vacuum cleaner with more suction power, but I gave it a whirl!
