I spent a lot of time researching and evaluating several models before finding this one at $28.5k. Ordered, they delivered two hours later, and everything was ok. White is a widely used version and color. It operates fairly softly at the middle level. Wet cleaning: wipes well, but obviously does not shine the floor. The initial map construction. I spent a half-hour connecting and configuring the application; I must be getting older. Surprisingly, I entered and exited the bathroom through a 25mm threshold. Though not on the first attempt. Stubborn) Definitely a good investment.
