This Shark Rotator Lift-Away Duo-Clean Pro Vacuum is one of the most powerful and versatile vacuums that I have ever owned! I had already used my other vacuum to clean the entire house and then I put this vacuum together and re-vacuumed my home and the canister was completely full! In addition, with a push of a button, you can remove the canister from the base and easily vacuum stairs, high corners, and all hard to reach places. I highly recommend this vacuum to anyone who wants a clean house on the first pass with the vacuum and/or has hard to reach spaces that you would like to have clean!
