Pudu Robotics Unveils the Tomo S Series: A Robot Lawn Mower That Sharpens Its Own Blades
Pudu Robotics has announced the Tomo S Series, a new line of robotic mowers built around a self-sharpening blade system. According to T3, the design aims to deliver consistently clean cuts while cutting down on routine maintenance, a pain point for many owners of a robot lawn mower.
What Is the Tomo S Series?
The Tomo S Series is a three-model range of autonomous lawn mowers covering lawns from 1,500 m² (0.37 acres) up to 5,000 m² (1.24 acres), according to T3's report. Pudu Robotics has not yet announced pricing or regional availability, and T3 says sales are expected to begin in early spring 2027. Interested buyers can sign up for updates through the brand's website.
The Headline Feature: SharpLoop Self-Sharpening
The standout feature is the SharpLoop Self-Sharpening System. As T3 describes it, the mower automatically sharpens its rotary blades at the charging station when needed. The goal is to maintain cutting performance over time and spare owners the chore of regularly removing and replacing blades.
Blade upkeep is a recurring task for anyone running smart mowing equipment, so a system that handles it automatically at the dock is a notable idea. The source doesn't give details on how often sharpening occurs or how long the blades last, so those points remain unknown for now.
Built for Tougher Grass Conditions
Pudu Robotics also highlights a Lift-Cut-Discharge System aimed at taller, denser and wetter grass. Per T3, the setup includes:
- Dual 636W high-torque motors driving the blades at up to 6,000 RPM
- Aerodynamic high-lift blades that raise flattened grass into the cutting path
- A dedicated rear discharge channel that directs clippings away to help prevent buildup and blockages
Edge Cutting, Slopes and Navigation
The Tomo S Series also includes Zero Edge Cutting, which combines an offset cutting deck, intelligent side sensing and a responsive bumper. T3 reports that this helps the mower follow walls, trees, flower beds and lawn boundaries more closely, reducing uncut strips and the need for manual trimming.
Other features listed in the report:
- Slope handling up to 45°
- Triple-Sense Navigation, combining 360° LiDAR, AI Vision and network RTK for centimetre-level positioning
- One-Tap Auto Mapping for easier setup
The mix of LiDAR, vision and RTK reflects a broader trend in the category toward multi-sensor navigation, which is increasingly common among higher-end models of robot lawn mower.
What This Means for You
If you're shopping for a robotic mower for a mid-sized to large yard, the Tomo S Series is worth keeping on your radar, though not yet on your shopping list. With sales not expected until early spring 2027 and no pricing announced, there is nothing to buy or budget for today.
For homeowners, the appeal is the promise of less hands-on maintenance, especially around blades. For landscaping pros evaluating automation, the stated 5,000 m² upper range and the focus on denser, wetter grass may be of interest, but real-world performance claims will need independent reviews once units ship. Everything above is based on Pudu Robotics' announced features as reported by T3, not on independent evaluation.
