I robot is initially very noisy ... impossible to follow a program together aspiration. Best to start when starting to return home in a well refreshed. The bin is emptied after each use !! Robot I do not like modern chairs and gets tangled in the chair bar ... we must prepare the ground and put the chairs on the tables. I almost robot passes under all the furniture ... except ... our buffet, then insists it is too thick, wedge, suddenly, it is required to place objects along the cabinet to force him to avoid this furniture. I robot does not like the cables that trainent.Prendre care not to let anything drag. Otherwise it's still a good everyday hand.
