The Bottom Line
Where the Niya Sonar 20 Fits
Best For
Flat-bottom above-ground pools wanting a basic cordless leaf-and-sand sweep around $199.
What We’d Buy
A basic cordless floor sweeper for flat above-ground pools. It handles loose debris but does not actively scrub algae or filter fine silt.
When a Full Cleaner Makes More Sense
The Niya Sonar 20 handles loose leaves on flat above-ground liners, but its coarse basket can pass fine seam dust and it has no spinning brush. Compare the Dolphin E10 for active floor scrubbing or the Dolphin Escape for a larger basket and optional fine filters.
The Niya Sonar 20 is a cordless robotic pool cleaner from Maytronics, rated for above-ground pools. It cleans the pool floor only (no wall climbing).
Filtration is a coarse filter with top access. The robot weighs 10 lb and carries a 1-year Maytronics warranty.
