PUDU TOMO S: A Robot Mower Designed to Sharpen Its Blades
PUDU TOMO S is designed to sharpen its own blades at the charging station. That is the most distinctive feature of the PUDU Home robotic mower family announced on 3 November 2026. PUDU is bringing its commercial robotics experience into the garden, but this is still a product announcement: sales are planned for early spring 2027. Pricing and country-specific deliveries have not been confirmed.

We checked the announcement and official product website on 9 November 2026. This article separates the proposed design from claims that still need testing in a real garden. RoboMorrow has not tested TOMO S.
Why self-sharpening matters
The SharpLoop system is intended to sharpen the rotating blades automatically at the dock. It addresses a practical ownership task: inspecting and replacing cutting elements. It does not establish that owners can ignore grass buildup, impact damage or the underside of the mower. Restoring a cutting edge and repairing a chipped blade are different problems.
PUDU also treats lifting grass, cutting it and discharging the clippings as a coordinated system. It specifies two 636 W motors and speeds up to 6,000 rpm. These are manufacturer specifications, not RoboMorrow measurements or comparable results against competing mowers. Motor power alone cannot tell a buyer what the lawn will look like after several weeks.
Watch the official product film
The film introduces the mower and docking concept. It is promotional material from PUDU, rather than a long-term reliability test. We do not interpret it as proof that the mower can work through an entire season without maintenance.
Read the headline specifications with their limits
| Area | Manufacturer claim | What a buyer should verify |
|---|---|---|
| Lawn area | Variants covering 1,500–5,000 m² | Capacity of the chosen version with separate zones and realistic mowing hours |
| Navigation | LiDAR, vision and Network RTK | Correction coverage, connectivity and behaviour when the service is unavailable |
| Drive system | AWD; slopes up to 45° | Traction, boundary restrictions and the conditions of the stated limit |
| Uneven ground | Obstacle crossing up to 6 cm | Obstacle shape and clearance beneath the cutting assembly |
| Edges | Offset cutting deck and side sensing | Results beside walls, raised borders and flush paths |
| Availability | Early 2027 launch window | Regional price, delivery, servicing and connectivity terms |
A 45-degree slope is steep; it is not a 45-percent gradient. A maximum climbing specification also should not automatically be applied to sideways mowing, wet ground or manoeuvres near a drop. The manual for the final regional model will be the relevant reference for operating limits.
No local RTK station does not mean no dependencies
Network RTK receives correction data through a network service. Removing a separate reference station can make installation easier, but buyers still need to establish coverage and connection requirements. Do not assume that removing the antenna also removes subscription charges or makes correction access permanent. The sources reviewed do not settle those regional terms.
Combining sensing methods is interesting because open lawns, tree cover and narrow passages present different navigation problems. That is an assessment of the architecture, not proof of flawless coverage in every garden. Our guides to how local and Network RTK work and mowers without a local RTK station explain the distinctions.
Should you wait for TOMO S?
It belongs on your watchlist if blade maintenance and a larger mowing area are the main ownership problems you want to solve. Automatic sharpening could then be more valuable than another app feature. Before placing a reservation, ask for the complete system price, sharpening consumable costs and service arrangements for the dock mechanism.
For a garden with difficult navigation, a demonstration on your property will matter more. Choose a passage between zones, a shaded area beneath trees and a boundary beside a solid obstruction. Ask for travel in both directions and a return to the dock. That exercise tests site fit more usefully than one attractive shot of a mower crossing a clear lawn. Our guide to mowing beneath trees provides additional questions.
There is not enough evidence to call TOMO the best purchase of the 2027 season. There is enough to justify following the launch. Its most interesting promise addresses a mechanical problem that can eventually be measured: cutting quality and the time owners spend caring for blades.
Questions before release
Can I order a locally supported model now?
The reviewed sources do not confirm country-specific stock or delivery. A global announcement is different from a local retailer having the product ready to ship.
What will it cost in Europe?
No confirmed euro price was found in the official sources. We are not turning an estimate or a currency conversion into a retail offer.
Does self-sharpening make the mower maintenance-free?
No. Sharpening is one operation. Cleaning, inspection for damage and drive-system maintenance should still follow the manual and actual operating conditions.
