The WYBOT S2 Vision is a next-generation cordless robotic pool cleaner designed for inground pools up to 3,229 square feet. It targets homeowners who want a fully automated, intelligent cleaning solution that can handle heavy debris, navigate obstacles, and adapt to their pool's unique layout without manual intervention.
The standout feature is its AI Vision Camera, which scans the pool floor and walls in real time to detect dirt and avoid obstacles. Combined with the self-learning AI, the robot builds a personalized cleaning path over the first month, reportedly improving efficiency by up to 20x. In practice, this means fewer missed spots and more consistent results as the robot learns your pool's debris patterns and shape.
Performance is backed by a brushless motor and a 7800mAh battery that delivers up to 210 minutes of runtime on Eco floor mode. The 8-in-1 cleaning modes (including waterline, wall, floor, and full pool) plus 6 expert path patterns give you granular control via the WYBOT App or the onboard touch bar. Wall climbing is enhanced with upgraded sensors, ensuring the robot can scrub the waterline and vertical surfaces effectively.
Build quality appears solid, with factory water-testing before shipment to ensure reliability. The 2-year comprehensive protection adds confidence. However, the robot must be placed back in the water before each scheduled cleaning, which is a minor hassle. Also, the premium price may deter budget-conscious buyers, and with no user reviews yet, real-world performance remains to be seen.
Overall, the WYBOT S2 Vision is a compelling choice for pool owners who value intelligence and automation. Its AI-driven cleaning, long runtime, and versatile modes set a high bar for cordless pool cleaners. If you have a large inground pool and want a hands-off experience, this robot is worth the investment.

Buying Guide
AI Navigation vs. Smart Sensors
The WYBOT S2 Vision uses an advanced AI camera that learns your pool’s debris patterns over the first month. It adjusts its cleaning path to focus on heavy dirt, improving efficiency by up to 20 times. In contrast, the S2 Pro relies on ultrasonic and infrared sensors for intelligent path planning. If your pool has many obstacles like steps or drains, the S2 Vision’s camera can navigate more precisely. For a deeper dive into navigation technologies, check our review of dolphin liberty 300 vs liberty 400.
Battery Life and Charging
Battery runtime is crucial for large pools. The S2 Vision packs a 7,800mAh battery that runs up to 210 minutes in Eco floor mode. The S2 Pro has an 8,000mAh battery offering 210 to 240 minutes of runtime and charges fully in 4 hours. For pools near the 3,300 sq. ft. limit, the extra 30 minutes of the S2 Pro can mean a complete clean without recharging.
Cleaning Modes and Customization
Both models offer multiple cleaning modes via the WYBOT App. The S2 Vision provides 8 modes including AI Vision, Waterline Only, and Expert Mode with six path patterns (S‑shape, Cross, Star for floors; N‑shape, H‑shape, V‑shape for walls). The S2 Pro offers 7 modes and 6 cleaning paths. If you want the most tailored cleaning, the S2 Vision’s self-learning AI gives an edge. For more on specialized cleaning brushes, see our guide on the best pool cleaner wall climbing brush.
Filtration and Suction Power
The S2 Pro boasts a high-performance brushless motor with 3,692 GPH suction, combined with dual scrubbing brushes and a top‑load dual filtration system (cartridge plus fine sponge). The S2 Vision also uses a brushless motor and strong suction, but its filtration is less detailed in specifications. For pools with fine particles like algae or dust, the S2 Pro’s dual filtration ensures crystal‑clear water. If you need extra traction on slippery surfaces, our guide on the best pool robot traction brush can help.
Final Thoughts
Both the WYBOT S2 Vision AI Camera Cordless Pool Cleaners and the WYBOT S2 Cordless Robotic Pool Cleaner (also known as the S2 Pro) are excellent choices for inground pools. If you want cutting‑edge AI that learns your pool’s debris patterns and navigates obstacles with a camera, choose the S2 Vision. If you prefer longer runtime, stronger suction, and dual filtration for the largest pools, the S2 Pro is your best bet. Both come with a 2‑year warranty and are factory‑verified for reliability.
