Input:
I have a very large apartment with all bare floors. Once a week I sweep and use a dustbuster to pick up the piles, then wash all the floors using the Twist n Shout mop system. During that week, I use the dustbuster to just go over the floors between washings. Bending over using the dustbuster would just kill my back. I used this machine Sunday for the first time-wow-it's as strong as the dustbuster but I don't have to bend down at all. Today I used it again and got perfect results. I have a 55 lb. dog and it picks up all his hair with ease. I took the handle off and vacuumed my couch. I couldn't believe all the dog hair it swept up from the couch because I didn't even see the hair on the couch and my dog is black. Only reason to keep my dustbuster is to get behind the toilet and my tv stand. The Eureka doesn't fit there. Great Product!
