Yes, but check the brushes and seals.

Robotic pool cleaners are generally safe for vinyl liners, but you need to be picky about which model you buy and how you run it.

The main risk is the cleaner’s brushes. Hard nylon or scrubber-style brushes can scrape or wear down the vinyl over time. Look for models with soft, rubber-like fins or bristles specifically labeled “vinyl-safe.” Also check the seals around the wheels and underside — any sharp plastic edge or uneven seam can tear the liner if the cleaner gets stuck and drags.

Another thing: don’t let it run longer than necessary. Vinyl liners are softer than concrete or fiberglass, so constant friction from a heavy robot can accelerate wear, especially along corners and steps. Run it for a cycle or two, then pull it out. Leaving it in the water for days is asking for trouble.

I’d also avoid the cheapest robots. They often have cheaper plastic parts with burrs or rough mold lines that can scratch. Stick with a mid-range name brand that acknowledges vinyl liner use in its specs.

Just don’t let it run on a torn liner.
