She wiped up her savings to hire Xiomi and Khobot, two more floor polishers, after he left. They are more effective. But I have to say, it's worse than the old Skuba (ai-robotic), which was abruptly phased out of service for no good reason. I owned not one but two of them, an earlier and a newer version. The previous version of Skuba (a washing AI robot) was therefore more effective. He sprayed water and then swept up the droplets together with the leftover food and garbage. It was enjoyable to me. I also have more than one level, so I acquired a second vacuum cleaner so that I wouldn't have to constantly drag the first one from room to room. While the model is newer, a change in washing methodology made it perform similarly to an older version. They didn't update Skub, but instead debuted the faceless i-robot Brava. It's worth noting that I have shiny floors, so any imperfections are accentuated. Then I'll have a basis for comparison. For the past fifteen years, this is the only cleaner I've used. It just so happens that today I am employing the services of five distinct brands of robots. If you want my honest opinion, don't waste your money or your sanity on an i-Robot Brava because of how poorly it cleans.
