First off the Shark Rotator vacuum replaced another highly recommended brand vacuum and blew it out of the water on suction and the convertible functionality! I love the ability to take the canister off the upright vacuum and being able to easily vacuum steps and baseboards. The suction is amazing and I have yet to have a loss of suction even when sweeping up a lot of dog hair. Which is another great thing about this vacuum that it self cleans the brushroll and it does a great job of doing that also! Highly recommended!
