I've had this vacuum for a few weeks now and I love it! I live in a small three bedroom house with three adults, two dogs and four cats. Our old shark (designed for carpets and hard floors) didn't pick up hair on hard wood floors. It just gathered around the brush roll. The new vacuum cleaner sucks without any problems! Nothing got stuck in the brush roller, but if it does, it's easy to clean! With all the different functions and attachments I can get to EVERYTHING! Finally, I like the headlights in front! I had no idea how much hair and dirt was on my floor!
