Clean Settled Sand, Then Find the Source
A robot can collect a light or moderate layer of settled sand when its floor path reaches the deposit and its filter retains the grain size. It may push some material on the first pass, especially in seams, corners, or a dense pile. Let disturbed grit settle before deciding whether another cycle is useful.
Very fine material may need finer filter media; coarser grains may be retained by standard media with more usable capacity. The right choice depends on what is actually on the floor, not a universal filter ranking.
Check Recurring Deposits
Common sources include landscaping, toys, towels, swimmers, wind-blown grit, and runoff. If sand-like material repeatedly appears beneath return jets, ask a qualified pool professional to inspect the circulation filter. A robotic cleaner cannot repair a damaged filter component or stop material entering the pool.
Protect the Cleaner After Sandy Cycles
- Remove leaves and stones before the cycle so the intake can focus on grit.
- Empty and rinse the filter promptly; do not let abrasive debris dry into moving areas.
- Inspect accessible intake and brush areas according to the manual, with the cleaner disconnected.
- Follow the maintenance guide and avoid dismantling sealed components.
For powdery desert deposits, use the dust guide. Owners of above-ground pools should also make sure that the selected cleaner is approved for their pool type and surface.
