Window wiper robot

This robot does not wash, but wipes.
Disadvantages:
- The dirt is spread, it takes several passes to get to a roughly correct result.
- The quality of the cloth provided to the studding is insufficient. I got a better result (but not perfect) tinkering with me studding supermarket micro fiber cloths.
- The best (but not perfect) results I got was after three or four passages with very clean, dry microfiber.
- Attention, you can not do a first pass with wet wipes, the robot will spin, and may fall. A dry, it hangs well.

Advantage:
- Allows you to wipe inaccessible windows. This is what makes that it is not left at the seller illico.

Improvements:
- Provide true micro-fiber last generation.
- Add multiple wiping programs on the remote. It does not matter if it takes longer. I had a better result with a narrow bay (40cm), because his way of making the edges that he stayed longer wiping the glass.

CONCLUSION:
What a shame not to get a better result. We spend hours, with the cat, watching the work, sitting on the couch ;-)
