If you have a Wybot Osprey 700 Max or S1, stop using and charging it now and check the serial number inside the top cover against the CPSC list. Affected owners get a free Wybot C2 with a prepaid return label. Until it is collected, store the robot away from anything that can burn and not in an attached garage.
The US Consumer Product Safety Commission announced recall 26-372 on April 9, 2026, covering about 5,000 Wybot robotic pool vacuums made by Wybotics. The lithium ion battery can overheat, which creates burn and fire hazards.
Two models are included: the Osprey 700 Max, model numbers WY3312MAX and WY100MAX, and the S1, model number WY200. Both are grey and blue, weigh about 17 pounds and have the Wybot name on the top or front.
Only certain serial numbers are recalled. The serial is a label inside the top cover, after the model name. Recalled Osprey 700 Max serials begin with WY100M230117, WY100M230127, WY100M230130 or WY100M230318. Recalled S1 serials begin with WY200 followed by 230328, or W200 followed by 230330. The last four digits can be anything. Check the CPSC notice for the exact format.
Wybotics received ten reports of the vacuums overheating or catching fire, both while charging and while not charging. Nine of those caused property damage. No injuries were reported. The notice does not say what caused the batteries to overheat, and it tells owners of all recalled units to stop using them, not only units that have shown a problem.
The units were sold on Amazon.com, BestBuy.com and Wybotpool.com for $500 to $700. The S1 was sold from April 2023 through September 2024 and the Osprey 700 Max from April 2023 through November 2024. Wybotics of Tianjin, China made them, and Wybotics Inc. of Arcadia, California imported them.
The remedy is a replacement, not a repair. Owners should stop using the vacuum and contact Wybotics at 888-991-5006, 9 a.m. to 5 p.m. Pacific, Monday to Friday, or [email protected]. The company sends a free return label and ships a new Wybot C2 within 15 days of receiving the old unit. Wybotics says it is contacting known buyers directly. Do not put a recalled unit in household trash, since damaged lithium ion batteries can start fires.
This is not the first battery recall for cordless pool robots. In March 2025, Aiper recalled about 32,660 Seagull Pro units in the US for the same kind of hazard. The Pool Nerd also reports getting a recall alert tied to a Wybot A1, which is not on the CPSC list, so owners of other Wybot models may want to check their serial numbers anyway.
The replacement Wybot C2 is listed as on sale on our pool rankings. The recalled Osprey 700 Max and S1 are not.
