First of all I have to say my wife and I are absolutely delighted with this small miracle robot. We even have a German Shepherd in the house who did not just lose a little hair and it's for the little Roomba no problem to deal with it, whether carpet or tile. At the beginning we were a bit skeptical about whether he will cope with the dog hairs, which settle in the carpet and generally orderly comes in in the corners, but we were immediately instructed by the better. He flits everywhere underneath when it allows its height. It automatically detects stairways or other obstacles, so it can not fall anywhere also. It's really not a problem for him when he has free ride and to clean it regularly. The Roomba 580 already such. B. is a lot of accessories The 3 radio towers, with which one can separate several rooms so the little helpers also the different rooms clean after the series and also its charging station is at the end again. There is of course even without these towers, but then he goes from one room to another and then takes forever. On the other hand he also still has a remote control with which one also can control it and a programming function, where you can set the day and time of the cleaning start. Should order to achieve optimum cleaning results we rid the small Roomba from dirt and set hair at regular intervals, but this is not a big problem, because the Roomba is designed so that all components can be removed quickly with a few simple steps to clean it. So finally, I have to say that the iRobot Roomba 580 money is definitely worth it and I do not want him to miss. Who invented the device to you should wear on their hands! Just a tip part !!!
