Pudu Robotics, a company best known for delivery and cleaning robots used in hotels and restaurants, is moving into homeowners' backyards. On November 3, the company unveiled the PUDU TOMO S Series, a line of robotic lawn mowers it describes as the industry's first with blades that sharpen themselves automatically. The three models cover lawns from 1,500 to 5,000 square meters and are expected to go on sale starting in early spring 2027, according to the company's press release.
The pitch is simple: robotic mowers have gotten good at cutting grass on a schedule, but the blades underneath still dull the same way a kitchen knife does, and most owners never bother to replace or sharpen them. Pudu says TOMO S removes that step from the chore list entirely.
How does a mower sharpen its own blades?
TOMO S relies on what Pudu calls the SharpLoop system. Two 636-watt motors spin the cutting blades at up to 6,000 RPM, and when the mower docks at its charging station between sessions, an onboard mechanism grinds the blade edge back to spec without tools or manual handling. Pudu describes the cycle as "mow, return, sharpen, repeat," meaning sharpening happens every time the robot comes home to charge rather than on a seasonal schedule the owner has to remember.
The company argues that keeping blades sharp year-round, rather than letting them degrade over a season, produces a cleaner cut and reduces stress on grass stems, which can brown at the tips when torn by a dull blade instead of sliced.
How does it avoid flower beds, pets and tree roots?
Navigation relies on 360-degree LiDAR, AI-based computer vision and network-based real-time kinematic (RTK) positioning, which Pudu says delivers centimeter-level accuracy without a separate reference station on the property. Owners set boundaries with a "One-Tap Auto Mapping" feature instead of burying perimeter wire, a step that has long been one of the bigger hassles with older robotic mowers.
The deck is offset to one side, a design Pudu calls Zero Edge Cutting, paired with side sensing and a responsive bumper so the mower can trim close to a border without climbing onto it. Four independent hub motors let it handle slopes up to 45 degrees, and a floating deck with independent suspension lets it ride over obstacles up to 6 centimeters tall, such as exposed roots, rather than stalling against them.
Why is a commercial robotics company entering lawn care?
Pudu has built its business selling delivery, cleaning and hospitality robots to hotels, restaurants and retailers, and it opened a German headquarters earlier this year to push further into European commercial accounts. TOMO S marks a deliberate step into the consumer market, where it will compete with established outdoor robotics brands such as Husqvarna, Segway's Navimow line and Mammotion, all of which have added LiDAR-based, wire-free navigation to their own mowers over the past two years.
CEO Felix Zhang framed the move as consistent with the company's broader goals rather than a side project: "By reducing the routine work behind a well-kept lawn, we are bringing our mission of making work easier and life better into people's homes," he said in the announcement. Pudu has not disclosed pricing for the TOMO S Series, saying regional availability and cost details will appear on its consumer site, puduhome.com, ahead of the spring 2027 launch window.
