A tank-tread (not wheeled) robotic mower from Lymow, a startup founded by former SharkNinja robot-vacuum engineers.

Wire-free RTK-GNSS + camera navigation, claimed 45°/100% slope capability.

Reference Price
The original Lymow One is sold out in the US and Canada and no longer being sold — it has been replaced, not kept on sale alongside its successor. Current pricing is for the Lymow One Plus: $2,999 (5A charger) or $3,199 (10A charger), per Lymow's own site. Some retailer listings and promos still cite figures as low as $2,599–$2,799; treat any single figure as a snapshot rather than a fixed MSRP.
Sensors & Hardware
The tank-tread drive is Lymow One's defining feature, built for rough, sloped terrain. Obstacle avoidance combines an AI camera (claimed 25+ object types) with 5 ultrasonic sensors and 2 Hall sensors. A CES 2024 press release cited a 21-inch cutting width, but the shipped spec sheet lists 16 inches — an unresolved discrepancy between early marketing and the production unit.
Insights
Lymow advertises a maximum climbing slope of 45° (100% grade) for the One/One Plus, but independent hands-on testing from Tom's Guide and PCWorld found it actually manages slopes of roughly 30° — a real gap between the marketed spec and tested performance. Its rubber tank-tread drive is independently confirmed as the genuine differentiator behind that traction.
Current Lineup: One vs. One Plus
The original crowdfunded Lymow One is no longer a going product: it shipped to backers, then to retail, and is now listed as sold out in the US and Canada. Lymow One Plus — announced at CES 2026 and available since March 2026 — is the current model, sold in 5A ($2,999) and 10A ($3,199) charger variants with roughly 50% more peak cutting power (1,785W vs. the original's 1,200W) and improved navigation. This differs from a "sold alongside" framing: One Plus has succeeded One in the lineup rather than the two being sold side by side.
Firmware & Community
Closed platform
Lymow One / Lymow One Plus 10A has not released a public SDK, firmware repo, or developer API. Not currently listed in Builds & Mods.
Verified against Lymow's own official site and Kickstarter page, plus independent hands-on reviews from Tom's Guide and PCWorld, CES 2026 coverage of the One Plus launch (AndroidHeadlines), and coverage from New Atlas, Yanko Design, Notebookcheck, and PR Newswire. Lymow is a young company (founded 2022) that moved from crowdfunding to commercial retail — company-reported unit-shipped figures are self-reported and unverified. Pricing varies by source and appears promo-dependent. A cutting-width discrepancy exists between the CES 2024 press preview (21 in) and the shipped spec sheet (16 in). Claimed max slope (45°/100%) exceeds what independent testers actually observed (~30°). The original Lymow One is confirmed sold out in the US and Canada as of this writing and has been succeeded, not kept on sale alongside, the One Plus (5A $2,999 / 10A $3,199), which launched at CES 2026 and became available in March 2026.
