Not bad but quickly limited

The product seems interesting at first but it is difficult to find ideal conditions to use it.
This robot brush would be ideal in a large room containing little furniture. By cons, he does not like the carpet!
The use is very simple. Scratch is an electrostatic wipes provided in the device, it is placed on the ground, you press a button and go.
The problem with carpet: Scratch it and wipe it stands at the location concerned.
Another downside: to detect walls and other obstacles, he bumps into it (obviously not strong, it will not drop any object unless it is a very light object).
Another defect: it wanders randomly depending on the obstacles in which he stumbles and often returns to the same place before deciding to go unexplored areas.
By cons, it dusts off really well! This suggests, but the noise is not really annoying not strong at all.
In short, the device can be nice if you have large rooms without carpets and lazy (or no time) to pass the broom yourself. Otherwise, the device quickly proves useless.
