I have, many others have as well - it is safe to swim at fc levels up to slam for your cya as the cya binds some of the active chlorine. This is a use at your own risk tolerance situation. Maytronics says max chlorine level of 4ppm. They make no mention of cya nor the fc/cya relationship.
My fc level is NEVER 4ppm or below as my cya is generally 60-80ppm.
My bot lives in the pool pretty much all season.
This holds true for most TFP users yet many have dolphin cleaners & use them daily.

I generally don’t dose to slam level & throw the robot in - i let it fall a little & run it just before the next dose. I also use care to not pour liquid chlorine or any chems with it in the pool.
