I have an interesting opinion of this vacuum. We had three cats including a Persian at the time, that I asked for this particular vacuum for Christmas. Turns out there is a cheaper model that is basically identical except for a hand attachment, that we basically used like three times. The vacuum itself worked really well. The first day we got it home and put together, I ended up running it three times over the entire house because we realized how much the previous vacuum we'd had had missed. The filters in this vacuum were midrange expensive, and did have to be replaced every three months. As long as the filters were changed, it worked pretty well, but lost power eventually like any other device would. Slowly the thing started to die though. It lasted almost exactly three years. When it finally gave up on life, it very suddenly caught on fire. I am very sensitive to smells and I can say that it didn't smell like there was any electrical smell before hand. My neighbor said it was the belt that caught fire. By that point, we just had to replace it.
