Replaced 12 yr old Stealth (motor failed). New brush cleans the same. Year over year refinements include covered power cord and different quick releases.
Our original unit has the sock type cover, works well but difficult to remove for cleaning and re-installing with the sleeve is okay. This new type sock is very easy to put on and take off. The one problem I see with it that reduced my rating is that the stitching on the quilting is terrible and already coming unstitched. I don't expect it to last long at all. The concept is good the workmanship is terrible. David Shafman
