Before him there was a rumba of the 700th series, it cleaned much better. I was led by the seller's stories about new rollers and a container and bitterly regretted it. E5 is suitable for cleaning rooms of up to 10 squares, it is not capable of cleaning a large area due to the lack of navigation. It is better to buy 3 Chinese robots for this money and I think the apartment will be cleaner. I do not recommend.
