Best for
- Vinyl-lined in-ground pools
- Owners comparing cordless pool robots
- Pools where fine debris is a recurring problem
Watch for
- Do not assume every brush material is suitable for every liner
- Wrinkles and sharp transitions can affect navigation
- Heavy debris may need a large basket more than ultra-fine filtration
Start with explicit vinyl compatibility
The safest first filter is simple: the manufacturer should explicitly list vinyl as a supported surface. Do not infer compatibility from a generic “all pools” claim when a current product page provides a surface list.
Traction matters more than brute-force scrubbing
A vinyl liner does not need aggressive abrasion to look clean. Good pathing, stable wall contact and appropriate brush materials are more useful than chasing the most aggressive scrubbing claim.
Match filtration to your debris
Leaves and acorns favor basket capacity and easy emptying. Dust and fine sediment favor finer filtration. A dual-layer or replaceable fine-filter option can be more valuable than adding another cleaning mode.
Where current robots fit
Aiper currently lists vinyl among supported surfaces for the Scuba S1. WYBOT also lists vinyl compatibility on the C2 Vision. That makes both viable research candidates, but the final choice should still reflect pool size, steps, wall slope and debris.
Pool-equipment claims are often based on different pool sizes, operating modes or test conditions. Compare the same job, pool dimensions and ownership assumptions before choosing a product.
