Well.....there is one major design flaw with this vacuum. Yes, it has strong suction, it is light weight, and versatile.However, there is the fan right above the floor....The vacuum ends up blowing air out of this vent with such force, that all of the dust nearby ends up getting shot into the air. No matter how much suction power this vacuum has, most of the dust gets blown into the air. Definitely not good for us allergy sufferers.Maybe this doesn't seem to be a problem for people who only vacuum carpets.....or maybe they just can't see the dust flying as easily as I can with some wood floors.You would think the designers who created this model would have recognized this huge flaw. I don't recommend this product. Don't waste your money!
