A real little robot that cleans smoothly and silently !!! I had bought a SCOOBA 390 but from the first use this cleaning robot is revealed a disaster ... I spare you the details of my adventures with this SCOOBA but to summarize, my floors were dirtier after passing that before !!! In short, I went and exchanged against it, and there ... miracle, my floors are clean ... but clean ... Of course, the use, is somewhat different. It washes well and quickly provided there was no big stains encrusted ... and again, I think that after a regular wash every day, these spots should leave. Otherwise, there is the trick to spray the product on difficult stains before starting the robot and ... hop ... it passes, you're done. He works methodically, the entire room is cleaned, the walls and baseboards included, it is not lost, does not catch, one hears almost no short, it is very efficient. The permanent humidification system of the wipe works very well and is a great addition. The battery is quite fast (4 hours for a fully discharged battery and a battery life of 4 hours, it is !!!) Well, of course, it will never be worth a good scrub mop manual but extra each day waiting for the next big clean ... it's really good. Personally, I love and recommend.
