I purchased my 2nd shark approx 1 month ago. Lost the first to a flood. This time I got the Rotator w/dual brushes. I don't feel or see the improved cleaning of the power fins. and the exhuast blows into my face when it is at roughly 45 degrees (pushing away from you). the changed placement of the power cord hooks does not lend itself to ease. and the power switch and level controls were moved to canister top. Was easier access when on handle.
