I bought a robot vacuum cleaner for myself, in a one-room apartment. I looked at a simpler model so as not to overpay. iRobot Roomba 698 is normal for the price, with two brushes, it vacuums cleanly. I don't regret buying this one. Different pros: Design that cleanly cleans, I liked that it is inexpensive. And I didnβt want white, black is also not very good, gray looks good. Different cons: I don't see any cons, so far everything suits me. I did not want to wash, because it is a useless function.
