Vinyl liner + Dolphin A20

[justducky21]

Has anyone had any issue with the Dolphin scrubbing some of the Vinyl print off their pool near the water line?

I thought it was scrubbing the waterline a little too aggressively but if I use a stiffer bristled manual hand brush it still takes some of the print off just a little less so- so maybe it's the liner, not necessarily the robot.

Thoughts?

I have the equivalent of the S200 (Dohney Discovery) which is also the same as the A20. I have no problem at all with it rubbing off the vinyl paint. In fact I have several patches on the floor of my pool and it has not affected them either.
