The robot that docks and charges itself — A cordless floor, wall and waterline robot that parks on a dock hung on the pool wall, in the water, and charges there from a solar panel on the coping or from a plug. 4.2★ across 7 Amazon owners, too few to rank on, and testers found a full solar refill takes days.
How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.

- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.

Filtration is rated in microns (µm — millionths of a meter): the smallest particle the filter reliably traps, so a lower number is a finer filter. A human hair is ~70 µm; ultra-fine (~3–10 µm) catches the silt and dead algae that make water hazy. "µm not published" means the maker states no number — which is information in itself.
Pros
- Of the robots we found listed at $1,500 to $2,000 in October 2026, only this one and its camera sibling dock themselves: it returns to its wall dock below 20% battery and charges there, so it never leaves the water to charge
- Daily Mail Buyline's tester, with three children in the pool: "one of the most convenient cleaners we have tested"
- Solar or plug-in: the dock takes a DC charger too, about 3 hours from empty by WYBOT's manual
- Sold by WYBOT itself, with a 2-year warranty on its own store
Cons
- Solar is slow: Daily Mail found a full charge "would need at least a couple of days of good weather", and an owner says it sometimes can't finish a full clean on one charge
- The dock needs a flat, sunny, unobstructed wall over at least 4 feet of water, with no steps or ledge beneath; one owner with a freeform pool struggled to find one
- Docking is not guaranteed: one owner's robot stopped docking after a few days, and a kicked-loose robot has to be recovered by hand
- About 135 Wh of battery, roughly half the Aiper X1 Pro Max's 262 Wh, for a 2.5-hour rated cycle
- Only 7 Amazon ratings, shared by both colours, two of them from Australia — too few to rank on
Both critical reviews are about the dock. One owner's robot docked for its first few days and then stopped, so he drags it to the base with a hook; another, with a freeform pool, could not find a flat, sunny, unobstructed wall to hang the dock on and says solar charges so slowly he waits days or plugs it in.
2 of 7 ratings, both three stars, both US, both October 2026; no one- or two-star reviews on the listing · critical reviews read October 2026
“It charges very slowly and sometimes won’t complete a full wall / floor cleaning on a single charge, so you will have to wait a few days for it to recharge or plug it in, defeating the purpose”— Ron, Amazon owner review (3 stars, October 2026)
Pro review “Having it permanently hanging on the side of the pool won’t be for everyone, but this is one of the most convenient cleaners we have tested.”Hands-on test in a hopper-bottom pool with three children using it, rated 3/5 ("Convenient but inconsistent"); found a full solar charge needs "at least a couple of days of good weather"; quote matched verbatim 2026-10-13 (curl)— Tim Gee, Daily Mail Buyline
FAQ
Who is the WYBOT S2 Solar Cordless Robotic Pool Cleaner with Solar Charging Dock for?
You want the robot to put itself away: it parks on its own dock on the pool wall and charges there, so nothing comes out of the water between cleans. Fair warning from the testers and owners alike: the sun refills it over days, not hours, and the dock needs a flat, sunny stretch of wall over at least 4 feet of water.
What do owners say about the WYBOT S2 Solar Cordless Robotic Pool Cleaner with Solar Charging Dock?
4.2★ across 7 owner ratings (Amazon, read October 2026 · too thin to judge · listing-wide base · global base). What owners complain about: Both critical reviews are about the dock. One owner's robot docked for its first few days and then stopped, so he drags it to the base with a hook; another, with a freeform pool, could not find a flat, sunny, unobstructed wall to hang the dock on and says solar charges so slowly he waits days or plugs it in.

✓ Safety: no active recall — No CPSC recall covers the S2 Solar line (checked 2026-10-13). WYBOT's maker, Wybotics, recalled the S1 (WY200) and Osprey 700 Max (WY3312MAX, WY100MAX) on 2026-04-09 (CPSC #26372) for lithium-battery overheating; this model is not named. CPSC's product-name search for "WYBOT" returns nothing, because that recall names the models, not the brand; the recall-title search for robotic pool vacuums finds it.
