Are robotic pool cleaners safe for vinyl liners?

Yes, but check the brushes and seals. Look for models with soft, rubber-like fins or bristles labeled “vinyl-safe,” and ensure no sharp plastic edges or uneven seams on the wheels and underside. Don’t let it run longer than necessary—constant friction can accelerate wear on corners and steps. Avoid the cheapest robots; stick with a mid-range name brand that acknowledges vinyl liner use.
