Awesome performance! Even at low revs this thing has more power than the last two cars I've owned together. If you then switch to high, it will clean the floor UNDER the carpet. Within 20 minutes he doubled his weight because he gained so much weight that there were no other vacuums. I understand why everyone but a couple is giving 5 stars and I totally agree. It definitely gets 5 stars from me! Edit: After a week of use, our rugs are so much fluffier it looks like we got a new rug! We've considered replacing the carpet in our living room, but not right now. It's almost unbelievable that a vacuum cleaner can make such a difference. I'm so glad we got to try this car!
