You can go where you can not, but rough cleaning

This product has advantages and disadvantages:
** Strengths:
- It accesses without real difficulty in my high windows of 6.5 meters. I just have to start from the bottom, to the top of the remote control and then start cleaning. He goes down alone.
- It can go up to where I never cleaned before ...
- He works alone, it beeps when it has finished, simply lift it to put it on the next window
- Really quite clean my kitchen lacquered furniture
- It comes with 12 pairs of microfiber, this will often change as you really need a very clean microfiber wash the windows. Otherwise, you see all the circular tracks.
- The product is good, the suction system is effective

** Weak points:
- Sometimes slides on some windows, I do not understand why he can not get on 2 of 15 windows while they are in principle the same as the others. This happens for some programs. to compensate for this, I take the hand with the remote control by sending the very top, then I start the wash cycle from the top. Here, it works.
- Do not freak cleaning because it leaves embedded dirt and it has still nothing like a real hand wash. To imagine the result, take a microfiber dry, rub your windows with circular movements. That's what you get with the robot.
- It's still not a lot of noise, you will not watch TV at the same time!
- It must be super smart to figure out how to hang if dropped. I'm still looking ...

In conclusion, I am satisfied because it reaches the top of my windows I never passed before, so it's always better with than without, obviously. But for accessible windows, it's still pretty average, although I'm not a clean freak windows. Finally a good quality / price for the use I have.
