This super robot supposed to help me with my housework, is in fact not very éfficasse. First, it makes a noise of the devil. You may say that it can be programmed and therefore operate in my absence, except that it is better be present. Indeed he stops for a yes or a no, pass 20 times in the same place and royally ignores another, so be board behind him. Or is the time saved? Deplus it is very slow. To really clean a room of 15 square meters, it takes about 20 minutes. And it's still not perfect. So it's a gimmick, except that I do not have the means to have gadgets at this price! When the seller, I wait he contacts me. Not serious.
