I was quite surprised my windows were very dirty and it did a very good job. The only thing I was a little bit disappointed was it didn't have an Australian plug so I had to buy one.
If the window is very dirty, must watch it clean because it will fall for too much dirt on them, other than that, the cleaning job is fantastic! Love it ! Wish the price can be little lower. ????
have many windows and teenagers…the robot is a little noisy but I just leave the room while it works and it beeps when it is done in an area. I have only used it inside, have not really used the spray feature and keep it plugged in. Cleans great with 0% elbow grease. Comes with extra microfiber socks so the robot can keep working. Needs some supervision, and a little windex on all the hand and paw prints, but overall very pleased with my window cleaner robot.
