In conclusion, I would recommend taking a robot cheaper than 7-8 thousand if you want to play around. It makes no sense to overpay for an automatic sprayer. If you want a smarter robot - take a closer look at the quadrant options. Has some pros: Why do so many people rate 5*? Yes, because the company has a promotion - put a review on 5 * and get a set of napkins :). Has some cons: And now to the point: 1. Instruction - it needs to be completed for good. In particular, not a word about how the automatic sprayer works; 2. Followed the instructions, washed each window in 3 stages from the outside - stains remain. Also wiped down with a dry cloth. But I think this is the case with all robots. 3. The instructions wrote about the V4 artificial intelligence technology - the robot could not determine the end of the window twice and as a result could not complete the work - it had to be stopped by itself. The third time the robot rested against the top of the window and poked at the same place. In short, there is no artificial intelligence there. 4. Regarding the automatic sprayer, there is not enough button on the robot itself to enable this function so that you can use it without a remote control. 5. Also lacks an indicator for turning on the automatic sprayer 6. Well, it washes very slowly, only 0.24 sq. M / min. But as I understand it, all such robots have this. If you want to be smarter, take a closer look at quadrant robots. There the speed is 0.40-0.42 sq. M / min
