Input: This little vacuum is a good value. The main attachment is good for cleaning up pet hair or crumbs--there's suction on the top and bottom so it's great to stick in corners or behind couch cushions, etc. I keep it in my car to vacuum the seats and other nooks and crannies. But it's not the best on flat/hard surfaces. It's also not the best at getting dust if you don't attach the hose. The exhaust on the sides it really intense and might blow the dust away before you have a chance to vacuum it up. Also, if you don't empty the canister after every use or keep it upright, the dirt/hair/dust can just fall right out again. Finally, it's very loud. But for the price, it gets the job done and I'm pretty happy with it.
