I met in reviews that it turns off if a blockage occurs, we had it once when we accidentally sucked a toy mouse, I think that this protection, on the contrary, is excellent, it protects the vacuum cleaner from failure. In general, in cleaning for me now assistant number 1. I recommend With its pros. We have 5 cats and there is enough wool, a big detergent to get every time is annoying Works great with both wool and loose filler Wall mount is very convenient. Has some cons Of the minuses: noisy, especially when the turbo brush is running. Cats fainted :) Too heavy
