Yarbo: The All-Season Modular Yard Robot
One tracked chassis. Swappable modules. A mower in July, a snow blower in January, a leaf blower in October. It's the most ambitious idea in yard robotics — and it comes with the most complicated ownership record. Here's the full picture.
How it actually works
Forget "robot mower with attachments." The Yarbo Core is a tracked chassis carrying the battery, drive motors, and all navigation hardware. Every yard task is a module that bolts onto the Core — mower, snow blower, leaf blower, trimmer. Yarbo says swaps are tool-free and take under 2 minutes; one independent reviewer countered that "swapping modules can feel like wrangling a Dalek." Treat the 2-minute claim as best-case.
Navigation is RTK (Real-Time Kinematic) GPS (Global Positioning System) plus stereo vision cameras, an IMU (inertial measurement unit — motion sensors), and odometry — no buried boundary wire. Every kit includes Yarbo's own Data Center, a local RTK base station that talks to the robot by radio, so positioning works with no internet or cellular required. You walk the property once in the app and it maps itself.
Two Core versions exist: the Y40 (standard) and the Y40P (faster, more efficient, rated for up to 7 acres vs 6). Both take the same modules.
Kit pricing (list, October 2026)
| Kit | List price |
|---|---|
| Y40 Core alone | $3,999 |
| Y40 Core + Lawn Mower Pro Module | $5,999 |
| Y40 Core + Snow Blower Module Gen 2 | $6,199 |
| Y40 Core + Blower Module | $5,099 |
| Y40 Core + Snow Blower Gen 2 + Blower | $7,299 |
| Y40P Core + Snow Blower Module Gen 2 | $7,799 |
Kits include a 2-year limited warranty and 30-day returns. Bundles are consistently cheaper than buying the Core and modules separately.
The snow blower module — the specs
It auto-docks around 20% battery and resumes at 80%, and it can start itself when the weather turns — genuinely hands-free snow clearing for long driveways. The mower module, for reference: 20-inch cut, 0.8–4.0 inch height, ~120 minutes per charge, rated up to 6–7 acres twice-weekly (owners say that's optimistic).
Pros
- The only credible all-season modular yard robot on the market
- Snow module is the best-regarded piece — "a beast" for long driveways
- Local RTK base station included — centimeter accuracy, no internet needed
- Class-leading 70% slope rating for mowing
- Weather-triggered auto-start; auto-dock and resume
- Replaces three machines (mower + snow blower + leaf blower) on one platform
Cons
- Multiple Core replacements are common — one owner received his 4th Core in under a year
- Refurbished replacements have arrived damaged or dead on arrival
- Power-board failures reported; one documented Core fire mid-mow
- Tracked zero-point turns tear turf — confirmed by Yarbo support
- 150–200 lb machine — module swaps and maintenance are physical work
- Support experience reads like triage: ~34 days downtime logged on one ticket, auto-closed tickets, slow parts
- Water intrusion has killed Cores; software "still maturing"
- Not set-and-forget — owners say plainly it needs attention and rescues
The reliability record — read this before buying
We're going to be blunt, because $6,199 demands it. Yarbo's owner forums document hardware failure rates that would sink any other appliance category:
- Core swaps are routine. Owners report second, third, even fourth replacement Cores within a year — and replacements are often refurbished units, some arriving bent, dirty, or dead on arrival.
- Turf damage is real. The tracked chassis tears grass on zero-point turns, especially in front of the dock and in dead-end passes. Yarbo support has confirmed this behavior. Sandy soil is worst.
- Support is the sore spot. One blogger's ticket-by-ticket log shows ~34 days of downtime for a single mower issue, support asking questions already answered in the ticket, and a replacement arriving dead out of the box.
- It's heavy. Core plus battery is ~145 lb; add the mower module and you're muscling ~170 lb for swaps and maintenance.
To be fair: when it works, owners call it a glimpse of the future, and the snow module gets the most consistent praise of any piece. But go in with eyes open — this is a project, not an appliance.
Who should buy it: 1+ acre properties in snowy climates with long driveways, owned by tech-patient tinkerers who want one platform instead of three machines — and who can muscle 170 lbs and tolerate early-adopter risk.
Who should NOT: small or complex suburban lawns (frequent turns chew turf); anyone expecting set-and-forget; driveways steeper than 36% (20°); or anyone who just needs snow clearing on a short flat driveway — a $300–500 electric thrower beats a $6,199 robot on value there, full stop.
