I bought this unit after reading that "digital" the almost regarded as the best in its class, for my house and opening onto the garden with a dog, 2 cats, tiled floor and parquet flooring. By opening internal doors Nestor (this is how I lappelle) cleans all the pieces then returns to the charger to order him to perform this work pressing the large button and a second support after a few seconds, this is very simple, practice. It would have the dust bin is of the order of 2 times larger in order to receive all the dirt recovered during this operation. I have to press the Pause button to stop it and make a drain through the tray. Pressing the button after replacing the tank and Nestor continues his work. But its biggest flaw is that it does not warn when the tank is full and then continues its journey in not picking up anything! This fault therefore requires to exercise supervision or at least to come from time to time when working which prevents some benefit from its opportunities. Given the price of the handset I find it abnormal. It sucks out a little while. The entrance into the little tray sobturer however if something a little too big presents, a small blow Wave in these parts allows denlever any objects before running Nestor. Nestor stops and indicates whether the brush is entangled in something, if he is stuck (mest this happened under a chair Nestor doing the exact height) but it's very rare. Its use is generally very simple, it is effective but of course he can not go to a small corner where one can go with the hose-dun conventional vacuum cleaner. It makes little noise with the conventional brush. The "brush" in the interest of hairless not hang anything but is quite loud, so I prefer the first left at the check after use. Recharging ensures cleaning of the house. With the detection of bin full I would have given it 5 stars but this lack of detection is particularly regrettable.
