WYBOT S2 Solar Vision Review (2026): Does the AI Camera Fix the Solar Problem?

Quick Answer: The WYBOT S2 Solar Vision is the camera-equipped version of WYBOT’s solar-dock flagship, adding an AI Vision mode that WYBOT says cleans floors up to 20x faster — a claim PCWorld’s independent test backed up with 100% measured debris removal in floor-only mode. It won a CES Innovation Award in 2025 and currently lists at $1,599.99 on sale ($1,999.99 list) direct from WYBOT. But it shares the exact same solar-charging dock as the plain S2 Solar, and PCWorld found the same core problem: roughly 2.5 days to recharge from 19% to 100% using solar alone, plus a dock battery that dies overnight and knocks out the app connection — so the AI camera improves how it cleans, not the hands-off promise the dock is built around.

WYBOT sells two versions of its solar-dock flagship: the plain S2 Solar and this Solar Vision variant, which adds an AI-powered camera on top of identical dock hardware. The camera is a real, independently-verified upgrade for floor cleaning. Here’s what PCWorld’s testing found once you look past the CES award, and whether the extra mode is worth it given the dock’s shared limitations.

By the numbers

• Floor-cleaning accuracy: PCWorld measured 100% debris removal using AI Vision mode in floor-only testing — a genuinely strong, independently verified result for the camera WYBOT added over the plain S2 Solar.
• Solar recharge time: Unchanged from the plain S2 Solar — PCWorld measured roughly 2.5 days to go from 19% to 100% charge using the solar dock alone, in peak Texas summer sun.
• Battery split: 5,200 mAh in the robot and 2,600 mAh in the dock — the dock’s smaller buffer is, per PCWorld, “something of a mismatch” against the robot’s larger pack.
• Coverage: WYBOT rates it for pools up to 3,229 sq ft, matching the plain S2 Solar and the largest cordless figure in WYBOT’s current lineup.
• Recognition: Won a CES Innovation Award in 2025, WYBOT’s own listed accolade for the underwater solar-dock design this model shares with the plain S2 Solar.

What it does well

The AI camera genuinely improves floor cleaning. PCWorld’s 100% debris-removal result in AI Vision mode is a real, measured upgrade over sensor-only navigation — not just a marketing claim.

Strong wall and waterline scrubbing, same as the plain S2 Solar — PCWorld specifically praised the front-mounted scrubbers on both models.

An extra cleaning mode. Eight scheduling/cleaning modes versus seven on the base S2 Solar, giving slightly more control over how and when it runs.

Backup DC charging built in, so a slow solar day doesn’t strand the robot — you can plug the dock in directly for a faster, reliable charge.

Where it falls short

• The solar dock’s core problem is unfixed. The AI camera changes cleaning behavior, not charging speed — PCWorld’s 2.5-day recharge measurement from 19% to 100% is identical to the plain S2 Solar’s result, because both share the same dock hardware.
• Dock battery dies overnight. PCWorld reported the 2,600 mAh dock battery frequently ran out overnight, which knocked out wireless connectivity to the app until it recharged.
• App reliability issues. Frequent disconnects and inaccurate battery-level reporting in the app — a recurring complaint across several WYBOT models on this site.
• The solar panel is exposed to damage. PCWorld flagged the panel’s placement as vulnerable to foot traffic around the pool deck.
• AI Vision mode is floor-only, the same limitation WYBOT built into the C2 Vision’s camera — full-pool wall-and-waterline coverage still runs on the older sensor-only navigation.
• PCWorld’s bottom line was still a pass. Despite the camera improvement, the reviewer concluded: “I simply didn’t see enough savings in time or effort to justify the expense.”

WYBOT S2 Solar Vision vs the alternatives

The strangest part of shopping the Solar Vision right now is that it’s listed cheaper than the plain S2 Solar ($1,599.99 vs. $1,799.99) during WYBOT’s current promotion — meaning there’s little reason to buy the non-camera version at today’s prices. Against the WYBOT C2 Vision, the Solar Vision still covers more pool and drops the cord, but costs roughly $700-$900 more for a solar-charging benefit that PCWorld found doesn’t actually save time once you factor in the dock’s slow recharge and overnight battery drops. For most large-pool owners, the plug-in WYBOT C2 Vision remains the better value; see our full best WYBOT pool cleaner guide for the rest of the lineup.

Who should buy the WYBOT S2 Solar Vision

Buy it if you already want the S2 Solar’s large-pool coverage and solar dock, and would rather have the independently-verified AI floor-cleaning boost for roughly the same price (or less, at current sale pricing) than the plain model.

Skip it if the solar-charging pitch itself is the main draw — PCWorld’s testing shows the camera doesn’t fix the dock’s fundamental recharge problem. The WYBOT C2 Vision delivers the same AI-camera floor cleaning with a standard 3-hour plug-in charge for hundreds less. See our best cordless robotic pool cleaner guide for the full field.

The bottom line

The WYBOT S2 Solar Vision proves its AI camera works — PCWorld measured 100% debris removal in floor-only mode, a genuine upgrade over the plain S2 Solar. But the camera doesn’t address the solar dock’s actual weakness: a slow, mismatched charging system that still takes about 2.5 days to fully recharge from solar alone, plus a dock battery that dies overnight and disrupts app connectivity. At $1,599.99 on sale, it’s currently a better buy than its non-camera sibling, but PCWorld’s own conclusion stands for both: unless you’re committed to the solar-dock idea specifically, the WYBOT C2 Vision or Aiper Scuba S1 will clean just as well for considerably less money and less waiting.
