So, at 35 kg plus how do you get these robots up on the roof? Also do people find that the hose get stuck in between panels, and then how do you fix it if you’re that far removed from the robot? CheersRichard.

Does anyone clean them completely without detergent? Is it okay to use tap water? (I understand that the issue is the residue left by calcite, but still, those white marks can also be washed away by rain.)

any advice for a first robot ? Budget and handeling wise i would say the solarcleano m1. But the solarcleano f1 or the sunbotics are also intresting options. How do you guys manage you’r pure water from filter to the roof ?

After 2 passes on the panels with my F1 robot, I still have a mark right in the middle, as in the photo. Has this ever happened to any of you? And do you know how to prevent it from happening again?

Hey what kind of charger are you guys using for the M1 robot batteries? If someone can show me a Pic of one or a link to where I can buy one. Thanks guys.
