Why I have not bought before ..... !!! I am blown away to see "work" for me. I did not believe at first, but it really is not a "gadget". It really bump for you and it is a pleasure to watch suck ...... Well it's not quite over, but as it moves dust -before the aspirer- so it arrives to muddle as well. Most importantly it does not hang in front of the power cables lying around. Nothing stops him, he also sneaks behind the curtains to draw the ground. Only gripe: brusque approach to furniture. But I would make it for anything in the world ..... lol
