Hello,

I want to by an automatic cleaner and I checking the different types: Suction, Pressure or Robotic

I saw different comments on Pros and Cons of the forums.

My question: If I have regularly sand to clean, do the Suction cleaners will scratch my liner because of the friction of the rubber rim ? Is it more appropriate for me to have a Pressure cleaner ?

Thank you

Hugo
