Would you buy a robotic lawn mower that sharpens its own blades?
Pudu Robotics unveiled the PUDU TOMO S Series robotic lawn mower with self-sharpening blades on November 3, 2026. The product is announced rather than shipped, with sales expected in early spring 2027.
Why it matters
The mower's SharpLoop system automates blade maintenance, a task that normally requires manual work, pointing toward fully autonomous outdoor lawn care. The launch extends Pudu's commercial robotics business, which has already shipped 130,000 robots across 85 countries and regions, into the consumer and residential lawn market.
The announced specifications are a 636 W dual-motor drive turning blades at up to 6,000 RPM, with a 45° slope limit and 6 cm obstacle clearance, all as manufacturer-stated figures. Independent performance testing has not been reported, and real-world cutting results against these numbers remain unverified.
The players
Pudu Robotics
A commercial service-robot maker whose portfolio spans cleaning, delivery and outdoor robots, with 130,000 units shipped across 85 countries and regions and 1,900 patent applications worldwide.
The details
The PUDU TOMO S Series uses a SharpLoop Self-Sharpening System, which runs a cycle of mowing, returning to its charging station, sharpening its rotary blades, and repeating without manual tools. The mower also carries four independent high-torque hub motors for all-wheel drive, and a Triple-Sense Navigation setup that combines 360° LiDAR (laser-based distance sensing), AI Vision (camera-based object recognition), and network RTK (satellite-correction positioning) to move around a yard. One-Tap Auto Mapping lets the mower identify lawn boundaries and plan routes from its first run.
Timeline
November 3, 2026: Pudu Robotics unveils the PUDU TOMO S Series.
Early spring 2027: Sales of the PUDU TOMO S Series are expected to begin.
The Tech Race
The PUDU TOMO S Series extends Pudu's commercial robotics footprint into residential lawn care, where it competes with existing robotic mowers. The launch positions Pudu alongside other manufacturers pursuing autonomous outdoor maintenance, though the stub does not name specific competitors.
The PUDU TOMO S Series is announced but not yet on sale, with sales expected in early spring 2027 and no pricing disclosed. Homeowners with lawns from 0.37 to 1.24 acres are the target buyers, and the self-sharpening feature would remove the manual blade maintenance that typically accompanies a mower.
The takeaway
Watch for independent testing of the SharpLoop system's blade-sharpening cycle once units ship in early spring 2027. Whether the self-sharpening claim holds up across real lawns will show whether automated blade maintenance is practical at consumer scale.
What happens next
Sales of the PUDU TOMO S Series are expected in early spring 2027, when pricing and market availability should become clearer.
