I have been using a cordless vacuum for the carpets on my bedrooms. I know they are not as powerful as corded ones but the shear amount of dirt that this vacuum got up was shocking (and a little disturbing that there was that much dirt in my carpets). I love the allergen filter. The lighted attachment was a nice surprise and comes in very handy in corners and crevices. The other thing I'm really happy about is the lights on the front so even in less than perfect lighting situations you can still see very well. Hands down would recommend this product to my family and friends.
