In principle, the thing is not indispensable - washing by hand is 10 times better, but you have to spend the whole day washing all the mirrors and glasses + then your hands fall off from fatigue. If the budget allows and you want to save time and effort, then you can buy it, but it requires constant attention, because. for after the end of the wash, every 5 minutes you have to restart it (if you want a second wash). I would like it to have a smart navigation system that would not allow spraying liquid when approaching the edge of the glass, because. it splashes at certain time intervals when moving left and right and sometimes splashes stupidly on the frame. The spray system is not ideal - 30-40% of the liquid goes into the air. In the end - I recommend buying if you are ready to accept small flaws)
