then one side is really convenient because it cleanses the abscence, on the other hand it also leaves a lot ... so I'm often amazed at super it gets to pick, I empty Tray 1 to 2 times per week and yet it is not small, so it will pick up stuff I do not see, but it goes too far from the wall so it often remains along with complaints ... and he spends his time in the clothes hang inadvertently forgotten or the floor mat of the bathroom or between the legs of the chairs, the slightest cable and hop it's over, the vacuum cleaner has not gone anywhere! short, it is convenient but a walking time of 4 or 5 unless NOTHING dragged to his level! there is still room for improvement!
