You get what you pay for. Not a bad unit for $25. I was hoping for more suction. You have to have the car running for decent suction. Even then it's good for small, lightweight items (dust, small or debris). It doesn't do anything for pet hair. I like that it can do wet and dry. I haven't tried wet yet. And it is small enough to be portable, but with a decent capacity. It's not particularly loud.
