ComparisonPolaris EPIC 8520 and MOVA Rover X10

Up to three

All robot pool cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.

Where each one suits you.

The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.

Fit verdicts by condition for each robot
Condition Polaris EPIC 8520 MOVA Rover X10
Pool type
In-ground GoodPolaris rates this model specifically for in-ground pools up to 40 ft end to end, with a 50 ft cable. GoodAll four tests ran in in-ground pools, including one review's 8 x 4 m pool, with strong floor results.
Above-ground DependsNo above-ground compatibility is documented for the EPIC 8520; Polaris rates it specifically for in-ground pools up to 40 ft. DependsMOVA lists all pool types, but no test covered an above-ground pool, and it weighs 15.8 kg.
Mixed setup DependsDocumented only for in-ground pools up to 40 ft; an above-ground pool in a mixed setup falls outside that spec. DependsA mixed setup needs both pool types confirmed, and above-ground use has not been independently tested.
Pool size
Small (< 400 sqft) GoodA 50 ft cable and 40 ft maximum pool length comfortably exceed what a small pool requires to reach. GoodIt cleans small pools easily, though a hands-on review judged its size and price oversized for a garden pool.
Medium (400 – 800) GoodThe 40 ft maximum pool length and 50 ft cable are sized for a medium in-ground pool without extension. GoodOne review's 8 x 4 m pool was cleaned systematically, with leaves, sand and soil reliably picked up.
Large (> 800)they differ DependsRated to 40 ft end to end; a large pool near or beyond that length may exceed the documented maximum. GoodMOVA rates it for 500 m², and independent testing found runtime only slightly below the six-hour claim.
Debris load
Fine (sand / silt) GoodNo published filtration micron rating exists for the EPIC 8520's 4 L canister to judge fine-debris capture. GoodAn included 3 micron filter caught pollen and fine dirt in independent testing, though it clogs faster.
Leaves / large debris GoodOwner reviews credit the double-helix brush arrangement with scrubbing floors, walls and waterlines thoroughly across a full cycle. GoodIts 5 L basket and surface skimming collected leaves reliably in two independent tests.
Algae / heavy fouling DependsNo source describes performance against algae specifically; the 136 aggregated owner reviews focus on general debris and reach. DependsIndependent testing found light waterline deposits cleaned but old, stuck rims not removed; no algae test was run.
Coverage you want
Floor only GoodOne of two selectable modes cleans the floor only, driven by dual traction motors on independent brushes. GoodOne review found little left on the floor, and another saw systematic, thorough floor cleaning.
Floor + walls GoodThe wall-cleaning mode also includes the waterline; there is no mode limited to floor plus walls alone. GoodHands-on reviews found it climbs walls reliably with good adhesion.
Floor + walls + waterline GoodThe second of two modes scans and cleans floor, walls and waterline together in a single cycle. GoodHands-on reviews found waterline cleaning powerful, with the robot staying active at the top.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
