As I have the fc8710 / 01 ordered from Amazon, there were no reviews here in www was found except the manufacturing side nothing ... should I dare to 299 euros? I did it because of the overall height (at last one which fits under all my furniture) and because the battery is replaceable. The rest was daring ;-) But I was not disappointed. Test object was prepared kitchen with tiled floor. Few oatmeal here a crumbled biscuit, to a few hairs from the cat and last but not least a few extra collected dust bunnies. The battery was charged quickly, and off we went. What I ever liked very much: the robots thundered not permanently against furniture and doors, but turned in 90% of cases to advance. Also good: despite 4x chairs / table legs he did not hang or always came out on its own. When he left after about 20 minutes, the 15 square meters, up to a Haferflocke everything was clean. Hair, crumbs, cereal. BlitzBlank. Well-lit trash can full light. On closer inspection however, the bucket was not full, but the Wollmaus had in the entrance cross gesetzt.Nach 10 seconds was the problem resolved. After that, the battery still enough for 30 square meters - probably unprepared, so just a little dust. He then went automatically to the charging station. I can summarize only say that I do not regret the purchase. Instead of vacuuming can now be on the balcony ...
