Overall good, but expected more.

Before that, the 188 model was used for several years. There were no complaints. Yes, the corners were not washed, but the overall quality of the wash was a solid 5.
Here it turned out that the sprayer is pure marketing, and even the quality of washing was very disappointing. An incomprehensible algorithm, when, especially, it hits the window below, so when the lower part of the frame is touched, it squeaks and can drive down twice, or maybe stop once. Leaving the corners even more unwashed.
Verdict. Who wants to automate the washing process, then take the 188 model better. Yes, it is taller in dimensions, but the quality of washing is better.
I'm attaching a photo of the studs. In the photo with an unwashed corner, strong dirt is visible - this is after several years of washing with a 188 model. And the unwashed part, which is from the 388 model. Compare the difference. I am also attaching a photo with an unwashed edge of the window.

More disappointed with the purchase.

Pros

Automation of the window cleaning process. Automatic spraying of washing liquid.

Cons

1. Ultrasonic atomizer. It only works when there is no wind at all. If it's windy outside, you can forget about this feature. All liquid goes into the air. 2. Quality of a sink. Before that, there was a 188 model. Soap is flawless. Leave only unwashed corners. Here, not only does it sometimes not clean the corners, like the 188 model, it also leaves dirt pyramids around the perimeter of the window. Trite, the upper wheel sometimes does not reach the edge of the window. 3. Stops at a different starting point. And always on the left.
