A real pleasure to be replaced in this task! It sucks perfectly, despite that one must sometimes board behind him in the corners. It bypasses or even climbing the unimposing obstacles. It is a little quieter than conventional vacuum cleaner, but it takes more time for him to make a piece parfaitement.Pour my part, I do not regret one thing: not having bought earlier! Another positive point: the replacement parts that can be purchased separately, and available even years after purchase (experience of a friend). I put 4 stars and not 5 because I have not had the opportunity to compare it with other vacuums even gamme.Mais I highly recommend!
