Pudu Robotics unveiled the PUDU TOMO S Series on November 3, 2026, bringing the commercial-robotics company into residential lawn care with a mower line built around automated rotary-blade sharpening.
PUDU describes TOMO S as the world’s first self-sharpening rotary-blade robotic mower. Its SharpLoop system automatically sharpens the blades at the charging station when needed, creating a tool-free cycle of mowing, returning, sharpening and repeating. The design is intended to preserve cutting performance while reducing routine blade maintenance, replacement and direct handling of sharp blades.
Cutting and Lawn Finish
The Lift-Cut-Discharge system is designed for tall, dense and wet grass. Two 636 W high-torque motors drive the blades at up to 6,000 RPM, according to PUDU, while aerodynamic high-lift blades raise flattened grass into the cutting path. A rear discharge channel guides clippings away to limit buildup and blockages, reducing the manual clearing and repeat work associated with clogging.
Zero Edge Cutting combines an offset deck, intelligent side sensing and a responsive side bumper. Together, they position the cutting path near boundaries and guide the mower along walls, trees, flower beds and open lawn edges to reduce uncut strips and manual trimming. A 180-degree rear-wheel zero-turn system handles tight turns with less turf disruption, while alternating mowing directions and perimeter return routes are intended to limit visible tracks.
Terrain, Navigation and Controls
Four independent high-torque hub motors provide all-wheel drive. PUDU reports slope handling up to 45 degrees, while a floating cutting deck follows ground contours and independent suspension supports obstacle crossing up to 6 cm. The deck and suspension complement the drive system, allowing the mower to adapt to uneven surfaces and obstacles rather than relying on traction alone.
Triple-Sense Navigation combines LiDAR, AI Vision and network RTK, with PUDU reporting centimeter-level positioning without a local RTK reference station. The official product page specifies dual LiDAR comprising 360-degree and solid-state sensors for ranging around trees, beneath dense canopy and in low light. AI Vision recognizes multiple obstacle types and distinguishes mowable grass from non-lawn surfaces. One-Tap Auto Mapping identifies mowable areas and boundaries, then plans routes from the first run without boundary wires or manual mapping.
Connected controls carry that automation into planning and coverage. The AI Mowing Planner uses weather and location when connected online, Smart Recut re-mows missed spots, and owners can set mowing zones, cutting height, modes and angles. Battery capacity is listed at up to 15 Ah, with 315 W charging and temperature-adaptive battery protection. PUDU reports a 10%–90% charging time of two hours.
Three Versions and a 2027 Sales Window
The series comes in three versions for lawns from 1,500 m² (0.37 acres) to 5,000 m² (1.24 acres). PUDU expects sales to begin in early spring 2027.
The home line draws on PUDU’s “One Brain, Multiple Embodiments” architecture, which covers embodied navigation, manipulation and interaction, motion control and multi-robot coordination across different robot forms. PUDU reports more than 130,000 robots shipped across over 85 countries and regions. It connects that commercial base to its experience in product reliability, adaptability, efficient deployment and ongoing support.
CEO Felix Zhang described TOMO as an application of that commercial experience, extending automation from mowing through blade maintenance to reduce routine work and give users more time for everyday life.
TOMO S puts more of lawn care inside the robot’s own operating loop, from mapping and cutting to charging and blade upkeep. Pudu’s consumer expansion therefore depends on those systems working together across varied home lawns; that integration is the central test of its move from commercial deployments into home robotics.
