This is absolutely the worst excuse for a vacuum I've ever seen.  There are no rollers, so it hardly works on the carpet at all.  The suction is very weak as well.  When you use the "switch" to go to hardwood floors, it scrapes loudly against the wood floors.  I was terrified to scratch the wood floors, so I stopped immediately, boxed it up and sent it back to Amazon!  I'm SO disappointed.  DO NOT WASTE YOUR MONEY!
