A large glazed loggia and it is inconvenient to wash the windows. Review for those who are planning to purchase a robot. If you have easy access to the glass (eg sash) you do not need it. You yourself will wash everything faster and better. If the glass is difficult to access, then take it. minuses: - does not wash corners, but this is understandable due to the design - sometimes hangs in the middle of the sink and squeaks. you have to control it all the time and run it further from the remote control - food came out of the nest a couple of times. have to put it back in. - washing does not occur in one pass. three stages are required (passage to dry, with the agent and then again to dry). hence the large consumption of rags. But they are included in the package.
