After use, here are my conclusions:
- Noise level, it is rather reasonable. Nothing like a vacuum cleaner. My cats do not fear. One of them has even intrigued by this robot that walks alone.
- Level efficiency: to observe work, we realize that it does not go anywhere and he spends more time in one place. What is disturbing is that it starts a room and then passes into another before completing the first. This point can be set by using the block "virtual wall" provides, but in this case it must be present in the house to move Roomba from room to room.
Unlike the video presentation, at home, most of my furniture is too low for Roomba can pass underneath.
With regard to corners, it is really doing well. With its rotating side brush it back to him dust that lies along the furniture to suck.
Strangely, at home he spends much time in the room at the back of the apartment and is never of himself in the kitchen ...
It rides well on carpets, although they are a bit thick and shaggy.
- Level autonomy: we must think up the chairs before leaving and remove anything that may impede the (toys, curtains strips or chairs, electric cables ...). With us it is stuck between chairs in the dining room table: Can not stand alone.
The fact alone that it returns to its base to recharge is a very good point.
The fund that collects dust is small: it is quickly full.
- Time level: it is long! When it is absent, it does not realize it, but he has not 3/4 cleaned the apartment. He went back to its base without going anywhere.
- Level ease of use: you can set the French, but most words in English remains the default. The programming of the cleaning is a bit complicated, even with the instructions under the eyes.
In conclusion, I am rather pleasantly surprised by this. It fulfills its role even though it will not replace a real vacuum cleaner passed by a human (to the back of the furniture, on the couch ...). However, it helps to have to spend a lot less often self-vacuuming.
It is true that to find his own house when you come home at night is really nice. But I still not reassured when I know he walks alone at home ...
The price reflects all the technology it contains, but it is still a very substantial purchase for a complementary product to a conventional vacuum cleaner.
Allow 2 LR14 batteries to power the block "virtual wall".
