Key Notes
- Pudu’s SharpLoop system automatically sharpens TOMO S rotary blades at the charging station to reduce routine blade upkeep.
- The series combines lidar and vision with network RTK and lists all-wheel drive for slopes of up to 45 degrees.
- Three versions target lawns from 1,500 to 5,000 square metres with sales expected in early spring 2027 and pricing still unannounced.
Pudu Robotics has introduced the TOMO S Series, a family of home lawn-mowing robots that automatically sharpen their rotary blades at the charging station. The launch extends automation beyond driving and cutting to one of the recurring maintenance jobs behind robot mowing.
The company announced the series in Amsterdam on November 3. Three versions target lawns ranging from 1,500 to 5,000 square metres, with sales expected in early spring 2027. Pricing and regional availability were not specified in the release.
SharpLoop Brings Blade Care Into the Docking Cycle
Pudu calls the maintenance system SharpLoop. When sharpening is needed, the mower returns to its station and sharpens its blades automatically. The company says that cycle is intended to preserve cutting performance while reducing routine blade changes and hands-on upkeep.
That addresses a different part of ownership from navigation. A mower can follow its route successfully while its cutting edge gradually loses effectiveness. Integrating blade care into the operating cycle could reduce a recurring interruption, although the launch materials do not establish independent long-term maintenance results.
The cutting system also uses high-lift blades to raise flattened grass and a rear channel to discharge clippings. Pudu specifies blade speeds of up to 6,000 RPM and positions the arrangement for dense, tall and wet grass. Those are supplier specifications and intended applications rather than results from RobotsBeat testing.
Navigation Combines Lidar, Vision and Network RTK
The official product site describes Triple-Sense Navigation, combining 360-degree lidar, AI vision and network RTK positioning. Pudu says the mower can map lawn boundaries and plan routes without boundary wires or a local RTK reference station.
Removing a local reference station is a specific installation claim, not evidence that every positioning feature operates without external services. The important practical question is how the complete navigation system behaves around a particular property’s trees, structures and boundaries.
For edge cutting, an offset deck works with side sensing and bumper feedback. Rear-wheel zero-turn steering is intended to make tight turns with less turf disturbance. These features target the finishing work that can remain even after a robot has covered the main lawn area.
All-Wheel Drive Targets More Demanding Ground
Pudu lists four independently driven wheels, slopes of up to 45 degrees and obstacle crossing of up to 6 cm. The series also uses a floating cutting deck and independent suspension to follow changing ground contours.
The 45-degree figure is a slope-angle specification, not a 45 percent gradient. As with lawn-area ratings, it describes a stated operating capability rather than guaranteeing the same performance across every combination of ground condition, grass and route.
A Home Line Alongside Commercial Grounds Robots
TOMO brings Pudu’s consumer lawn-care plans alongside its established commercial portfolio. RobotsBeat previously covered the GT mower series for professional grounds and turf work, as well as the ET1 cleaning robot for smaller commercial spaces.
The distinction for TOMO is the combination of home mowing, automated blade care and installation-focused navigation features. Its early-2027 sales plan leaves pricing, regional rollout and real-world ownership experience as the next details to watch.
