The Oso Robotic Mower
The autonomous commercial robotic mower for scalable crews.
One operator can run multiple units across large properties simultaneously. The mower handles navigation, obstacle avoidance, and route optimization on its own.
The Benefits
Cover more ground with the same crew.
Autonomous mowing runs in parallel with your crew, so trimming, edging, and cleanup happen at the same time the grass gets cut. Finish jobs faster without adding labor.
Turn time savings into more revenue.
Shorter job times mean more flexibility. Wrap up earlier, reduce crew fatigue, or take on additional properties and grow your route without increasing headcount.
Know what every mower is doing at a glance.
Track battery levels, runtime, location, and maintenance alerts across your fleet from a single dashboard. Stay ahead of issues and keep crews moving without surprises.
The Features
Quick and easy setup, without wires
No boundary wires and no technician required after the first perimeter walk.* Once the GPS coordinates of your property are mapped, the mower can be dropped at the job site any time to to run a mow cycle.
Obstacle detection and rerouting
Advanced sensors identify obstacles in real time and navigate around them to continue the job. If a person or animal enters the 2-meter detection zone, the blade stops and the mower pauses immediately. Once the area is clear, mowing resumes automatically.
One operator, multiple mowers
A single crew member can monitor and manage several units running simultaneously across a large property. The same work gets done with fewer people on the clock.*
Software updates
Leave the mower connected to a battery overnight once a week and it updates itself automatically — navigation improvements, safety protocols, and new features push automatically over Wi-Fi. The mower you buy keeps getting better after purchase.
Built for the trailer
Rear-mounted tie-down anchors let you strap the mower down securely for transport. Load it, strap it, go.
Gas-equivalent cutting power
The brushless DC motor drives the blade at up to 3,400 RPM with torque that handles thick commercial grass, wet conditions, and demanding terrain without bogging down.
Easy battery swaps, all day power
The 35Ah LiFePO4 battery runs over two hours per charge. Bring a second battery on longer routes and you never stop for fuel. No gas station detours, no spill risk on client property.
Full fleet visibility optional add-on
Track every unit in real time from one dashboard. See location, battery level, runtime, and maintenance alerts across your entire operation.
Centimeter-level boundary accuracy
RTK GPS positioning keeps the mower precisely within its recorded boundary, delivering consistent stripe patterns on every visit.
Instant obstacle detection and stop
LiDAR continuously scans the area directly in front of and beside the mower, triggering an immediate motor stop the moment anything enters the safety zone.
Full-field awareness during every cut
Vision cameras actively monitor for obstacles and people throughout autonomous operation, adding a layer of awareness that positioning and proximity sensing alone cannot provide.
Continuous real-time decision making
The on-board computer fuses every sensor input simultaneously, managing navigation and safety without interruption from start to finish.
*Supervised operation required — operator must remain on-site with remote E-Stop during autonomous mowing.
The Savings
What gas is actually costing you.
Gas mowers average $1,500 per year in fuel and maintenance costs per machine. Oso’s electric mower runs on about $95 in electricity annually. Add in no oil changes, no belt replacements, and no carburetor cleanups, and the difference compounds fast. Here’s what that looks like across three usage levels.

The App
Smart features, built in.
Every robotic mower connects to the Oso cloud platform out of the box. From one dashboard you can see where every unit is, how long it has been running, what its battery level is, and whether it needs attention — across every property in your portfolio simultaneously. Maintenance alerts surface before problems become downtime. Route data logs automatically so you can see exactly what was cut, when, and for how long. For operations running multiple units, it means knowing your crew is productive across every property without having to check in on each one.
