So I need new climbing rings for my Maytronic M400, the original part is very expensive. Do you buy genuine or some other cheap alternatives that's possible to find online?
To the OP, looks like the rings on Amazon.se are about $20 USD, or $220Kr. That is about as good as it gets. I have used both aftermarket and OEM in the past. I liked the OEM, but I had both good and bad with the aftermarket (one set was fine the other struggled). Hope that helps!
Extension cords: Yeah, the manual is serious about not using them, and it’s not just legalese. Extension cords can cause voltage drops or even overheating, which messes with the power supply and could damage the unit. That said, most people don’t have an outlet right next to their pool. The best (and safest) workaround is to have an electrician install a weatherproof outlet closer to the pool. It’s annoying, but worth it for the long-term health of the unit.
Chlorine levels: The 4 ppm limit is real from the manufacturer’s side—they’re trying to protect the internal parts (seals, brushes, etc.) from chemical wear. I totally get that TFP folks run higher levels with CYA in the 70–80 range (same here, SWG pool), but just know that long-term use in 5–10 ppm could shorten the lifespan of the robot. Some people run the bot during lower FC times (early morning, evening, etc.), or just accept the tradeoff and factor in slightly faster wear over time.
