Lymow debuts Lymow One robotic mower

Lymow has unveiled its Lymow One, featuring an upgraded front mulching deck, LySee navigation and terrain adaptability.

"Most robotic mowers today are built for small yards, but many U.S. homes have large, complex lawns. As a result, these mowers often serve as a supplement rather than a true replacement for traditional mowers," says Wangshu Gao, founder and CEO of Lymow, who spent eight years at the helm of the R&D department at SharkNinja. "With Lymow One, we’re taking a different approach. Our product is designed to fully replace traditional mowers, delivering superior automated lawn care—better results, less time, lower costs, and minimal effort."

The Lymow One features a LyCut Dual Blade Mowing Deck, designed to handle all types of grass with ease. At its core is a shift from the previous lateral scissor blades to two high-speed spinning mulching blades, paired with a centrifugal fan integrated into the deck for optimal clipping discharge. This system tackles tough grass, dense patches, wet or dry conditions, and debris like fruit, pinecones, and small branches. It includes professional-grade mulching blades typically found on ride-on and traditional lawnmowers. Powered by an brushless motor with a peak output of 1200W, it drives the mulching blades to spin at 6000 RPM. The Lymow One's dual-blade front deck offers an effective cutting width of 16 inches. Users can choose from a side or rear discharge with a ClipFlex accessory.

The front deck of the Lymow One offers an adjustable cutting height from 1.2 to 4 inches, providing users with mowing flexibility. The mowing deck follows the ground with its omniwheels, guaranteeing even cuts on uneven terrain.

Lymow One’s LySee Multi-Fusion Navigation System combines Real-Time Kinematic (RTK) satellite positioning and Visual Simultaneous Localization and Mapping (VSLAM) technologies. The navigation technology eliminates the need for boundary wires, allowing for map editing of multiple zones and no-go areas. Its stereo camera also enables the Lymow One to perceive its surroundings and avoid obstacles for uninterrupted mowing.

By replacing traditional perimeter wires with RTK-VSLAM navigation, which provides centimeter-level accuracy, the Lymow One offers the convenience of easy setup and map management through the app. However, as a satellite-based system, RTK signals can be affected by trees, roofs, walls, or even bad weather. To address this, the Lymow One combines RTK with VSLAM technology, ensuring seamless navigation even during temporary RTK signal loss.

Lymow One’s stereo camera combines image-based semantic recognition with depth-sensing for a better understanding of its surroundings. Advanced algorithms allow it to identify and react to objects like hedgehogs, sprinklers and pet waste, avoiding them with ease. Users can customize its response to items such as fruits or pinecones through the Lymow app — either bypassing them or cutting them using the LyCut Mowing Deck.

its advanced sensor array includes five ultrasonic sensors, a pair of front bumpers, and off-ground sensors in the blade deck, creating multiple layers of protection. The blades can stop in under a second from full speed, offering reliable, responsive safety in any mowing scenario.

Lymow One’s smart path planning feature ensures perfectly aligned stripes, not random paths. Users can adjust the overlap between parallel stripes to their preference and even set the stripe angle to create checkerboard or diamond grid patterns. The mower's tracked tread propulsion covers 0.23 acres/hour, 0.57 acres/charge, and 1.73 acres/day. It can clear obstacles up to two inches in height and tackle slopes with a 45-degree (100%) gradient, even climbing stairs and performing reliably in wet weather and slippery conditions.

The Lymow One features FEM analysis for collision testing and boasts a one-piece die-cast aluminum alloy frame, similar to those found in sports cars. The LiFePO4 battery delivers over double the charge cycles of standard lithium-ion batteries. With an upgraded IPX6 waterproof rating, the Lymow One is designed to withstand all weather conditions, ensuring lasting reliability for years to come.

After the company's Kickstarter campaign that raised over $3.5 million, the Lymow One is now in production and slated for delivery in April 2025, priced at $2,999.
