The Roomba 780 does exactly what is promised in the description. He has to clean with us tiles in the entrance area and a living area with velor carpet and he does very well. Of course, one must a bit careful that the area is free and on absorbent well traversed, but this is a matter of course for me. Emptying the dust collecting container is simple and unproblematic Bürstwalzenreinigung using the tool supplied. This goes Ruck-Zuck. The noise level is OK. Certain places like corners or niches between furniture he can not reach, as must every now and then be sucked conventionally, as well as naturally on stairs. But I did not expect otherwise. It can also advance ungesaugt points but this is my opinion after not tragic, because it runs daily and the sites then just join in next time. He brings in any case always an amazing amount of dust out of the apartment. In short a great help with troublesome cleaning of flooring in the house. The price is quite high, here one should consider whether not enough another model. On the upper floor we have the Roomba 555 in use, also on carpet and tiles and makes the good. However, I feel it was a little louder and a little rickety and rumpeliger in appearance. As the more sensitive is the 780er pull over to obstacles. The contact clip bim 780er is rubberized at the bottom and thus gentler on the furniture than the plastic bracket when 555er. If the high price does not bother, then better take the 780er. Otherwise, the 555er in the price-performance ratio is an alternative.
