Robot mowers solved the mowing years ago. They never solved the blades. The small pivoting blades most of them run dull fast, rust, and need swapping by hand, and a mower cutting with a dull edge tears grass instead of cutting it.
Pudu’s TOMO S goes at that problem directly: when sharpening is due, it heads back to its charging station and sharpens its own rotary blades. No tools, no routine blade changes. It’s Pudu’s first consumer line, built by a company that has shipped more than 130,000 commercial robots into 85-plus countries.

Where to buy: PUDU HOME (orders open early spring 2027)
Three versions cover lawns from 1,500 to 5,000 square meters, about 0.37 to 1.24 acres. The self-sharpening dock pairs with all-wheel drive, wire-free navigation, and an offset deck that cuts to the edge, and the series goes on sale in early 2027.
Two wire-free AWD mowers you can buy while you wait
If your lawn needs a wire-free mower this season, these two match its brief, all-wheel drive, LiDAR navigation, no boundary wire, and both are in stock on Amazon today.

Mammotion LUBA mini 2 AWD 1500H
The mini 2 covers the same 0.37 acre as the smallest TOMO S and climbs 80 percent slopes (38.6 degrees) on four driven wheels. Its 360-degree LiDAR and dual cameras handle positioning without an RTK station to mount, and it manages up to 20 zones. The trade is upkeep: its blades are the standard replaceable kind, so the chore the TOMO S automates at the dock is still yours here.

Dreame A3 AWD Pro 3500
The Dreame covers 0.87 acre, pairs a 360-degree 3D LiDAR with binocular AI vision, and crosses obstacles up to 2.2 inches on the same 80 percent slope rating. Its dual discs cut a 15.8-inch path, twice the width of the Mammotion, so it finishes big lawns faster. You pay $600.99 more for that coverage and width, and its blades need the same manual changes.

SharpLoop does the blade work at the dock
The cycle runs on its own: mow, return, sharpen, repeat. When sharpening is due, the TOMO S docks and SharpLoop brings the rotary blades back to an edge, so cut quality doesn’t slide as the weeks pass. The blades are full rotary blades rather than the small pivoting cutters most robot mowers carry, and Pudu’s own lab comparison shows its rotary blades still sharp and rust-resistant after three years, where small blades show dull and rust-prone after one month.
That’s a manufacturer test, labeled as one, but the maintenance math holds either way: a blade sharpened automatically on schedule never needs the swap-out routine, and a sharp edge slices grass cleanly instead of tearing it.
Lift-Cut-Discharge is built for grass that fights back
Tall, dense, and wet grass is where robot mowers clog and give up. The TOMO S drives aerodynamic high-lift blades with dual 636-watt motors at up to 6,000 RPM, so flattened grass gets lifted into the cutting path instead of pushed over. A dedicated rear discharge channel moves clippings out before they pack in and stall the deck. The cutting deck floats, following the lawn’s contours as it works, which keeps the cut even when the ground isn’t.
Edges, turns, and a clean way home
An offset cutting deck, intelligent side sensing, and a responsive side bumper let the TOMO S cut right up to walls, trees, and flower beds, so the uncut border you’d normally finish with a string trimmer shrinks to a sliver. At the end of a pass, the rear wheels swing the mower through a 180-degree zero-turn in one smooth move, with no back-and-forth shuffle tearing at the turf. When the job’s done, it returns to its dock along the perimeter instead of across the lawn, so no worn track gets cut through the middle of your grass.
Triple-Sense Navigation maps the lawn on the first run
There’s no boundary wire to peg out and no RTK base station to bolt to a fence. Triple-Sense Navigation combines a 360-degree LiDAR, AI vision, and network RTK for centimeter-level positioning, and One-Tap Auto Mapping identifies the mowable areas and boundaries on the first run, then plans the routes itself.
Four independent hub motors give the TOMO S all-wheel drive for slopes up to 45 degrees on Pudu’s figure, and independent suspension carries it over obstacles up to 6 centimeters. In the app, the AI Mowing Planner works around your weather and location, Smart Recut sends the mower back over any missed spots, and zones, cutting height, modes, and angles are all yours to set.
Sales start in early 2027 and the price is still unannounced
Pudu hasn’t priced any of the three versions, and regional availability hasn’t been announced either, so for now it’s the subscribe button on PUDU HOME and a wait until early spring. What you’re waiting on is a genuine first for the category, claimed by Pudu and not contradicted by anything else on the market: a mower that maintains its own blades. If the TOMO S lands priced in line with the AWD LiDAR mowers above, the dock is the reason to pick it over them.

Where to buy: PUDU HOME (orders open early spring 2027)
Pudu spent a decade putting robots to work in hotels, stores, and restaurants, and the TOMO S points that experience at the one chore robot mowers never finished. Mowing got automated years ago. Blade care didn’t. This mower closes that gap, and the rest of the sheet, all-wheel drive, wire-free mapping, edge cutting that reaches the fence line, is built to the same standard.
