In only 3 months of use, just cleaning our downstairs area, the wheels have developed a very loud screeching sound when in use. The wheels have developed a major resistance, so it's hard to push. Today, the rubber covering one of the wheels sheared off, which ended up scratching my Amtico floor. I guess this is what I get for not using my Dyson instead. Stay well away! On the feature side, I was extremely keen on the mopping attachment. Unfortunately in use, it's a major gimmick. I need to walk around with a spray bottle, or when the floors are stained, a mop and bucket, in order to sufficiently wet the floor. This of course defeats the purpose of having a mop attachment!
