Sand is heavy and abrasive. It sinks fast, packs into the deep end and floor seams, and can blow in constantly if you live near a beach, desert, or a sandy backyard. A robot has to lift dense grit off the floor and hold it — not just brush it into a cloud.
The winning combination is strong suction to lift settled sand plus fine filtration to keep the finest grains from washing back out. Brushes help dislodge sand packed into textured surfaces and corners.

Max-Series
Strong dual HyperBrush pickup plus NanoFilters lift and hold dense sand; the XXL MaxBin means you're not emptying grit constantly.
Flagship ProLine
Commercial motors deliver the suction to lift settled sand, and ultra-fine media keeps the smallest grains captured.
Most Advanced ProLine
Quad brushes dig sand out of textured floors and steps that suction-only robots skim over.
Not all pool debris is created equal. Big, buoyant leaves need a huge basket and strong pickup; fine pollen and silt slip straight through cheap mesh filters. The right robotic pool cleaner is the one matched to what actually lands in your water.
Fine debris (pollen, silt, dust, dead algae) demands NanoFiltration down to 2 microns. Standard mesh baskets let these particles wash right back into the pool, leaving it cloudy even after a full cycle.
Bulk debris (leaves, acorns, twigs) fills a basket fast. Look for an oversized top-load bin or a swappable leaf bag so the robot finishes the job without clogging mid-cycle.
Sticky or bonded debris — algae film, bug residue, ground-in dirt — needs active brushes, not just suction. HyperBrush and quad-brush systems lift what suction alone leaves behind.
Higher GPH flow lifts heavier and settled debris off the floor. Weak pumps stir fine debris up without capturing it.

Match the robot to the job
Sand settles into the lowest points and wedges into surface texture. Weak robots stir it into suspension but let it drain back through coarse mesh. You need lift, fine capture, and good floor contact.
Yes, if it has enough suction and fine filtration. Sand is dense, so weak pumps just push it around. Models like the Quantum and Premier lift settled sand off the floor and trap even fine grains in NanoFilters.
Quality robots are built to handle grit, but always rinse the filter after sandy cycles so abrasive particles don't wear internal parts. Fine filtration also reduces how much sand recirculates through the impeller.
Use a NanoFiltration model. Coarse baskets let the finest sand pass back through; 2-micron filtration captures it so the water clears and stays clear.
