S2 Solar against the pool cleaners we track

Pool capacitymore is better: 3,229sq ft
Tech Specs table lists Ideal Pool Size Up to 3229 sq ft; Pool Classification Outdoor In Ground Pool. Water depth max 9.8 ft. Manufacturer figure, no measurement basis stated.
Runtimemore is better: 150min
Published as Working Cycle Up to 150 mins, an up-to figure with no mode basis stated on the US spec table; marketing restates it as 2.5h+ runtime. The solar dock is claimed to enable uninterrupted continuous operation, a different basis than battery-only runtime (see specNotes).
Flow ratemore is better: 3,962GPH
Tech Specs labels this Average Suction Rate: 3962 GPH (an average-rate label, unlike peers' unstated or peak bases). The only flow figure on the US page; no conflicting figure appears.
Filtration (finest layer)less is better: 180µm
Tech Specs: 180 micron Regular Filter Basket plus 40 ppi sponge. Marketing describes a 3D Adsorption System with 180 micron filter box and ultra-fine sponge; 180 is the finest micron-rated layer published.
Charge timeless is better: 3hr

Notes & caveats

Variant chosen: WYBOT S2 Solar with Solar-Powered Charging Dock, the base S2 Solar with a full US Tech Specs table, NOT the S2 Solar Vision and NOT the C2 Vision (already on the site). Battery: lithium 5200 mAh; input 100-240V AC; DC output 29.4V/3A, 90W. IP68; moving speed 33 ft/min; 7 cleaning modes in app; brushless motor. Battery and temperature spec block carries the disclaimer: tested in a laboratory environment and should be used for reference only. Solar basis: marketing claims uninterrupted cleaning via the solar dock and calls it the world's first underwater solar-powered robotic pool cleaner with dual solar and DC charging, a basis distinct from the 150-min battery-only working cycle. weightLbs is the robot weight (46.3 lb); gross package weight 70.5 lb.
