All multi-task robots. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
These robots are asked different questions. 3 of them overlap and are compared below; the rest are on each robot’s own page.
| Condition | Y40P Core Snow Blower | Yarbo S1 |
|---|---|---|
| Area to clear or mow | ||
| Under ¼ acre | GoodOne charge is rated for up to 7,000 square feet in one inch of snow, by the maker. | GoodRated to 0.75 acre per charge; a multi-module RTK platform is more machine than a quarter-acre lot typically needs. |
| ¼ – ½ acrethey differ | DependsPaved area above 7,000 square feet takes more than one charge. A recharge to 80 percent takes about 90 minutes. | GoodFalls inside the platform's rated 0.75-acre-per-charge coverage, the range Yarbo's own documentation targets for this system. |
| Over ½ acrethey differ | DependsA long drive needs several charge cycles per storm. No independent test at this scale is held here. | GoodYarbo documents this GPS-guided platform scaling well past half an acre, with a rated 32,700 sq ft coverage per charge. |
| Terrain | ||
| Mostly flat | GoodTracked hub-motor drive, with a snow track in the box. Flat driveways sit well inside the ratings. | GoodOne reviewer reports ordinary suburban lawn terrain handled without trouble on this platform's mowing module. |
| Gentle slopesthey differ | DependsRated for slopes up to 36 percent while clearing snow. The figure is the maker's, with no independent test. | GoodRated to a 70 percent gradient and one reviewer found inclines handled without trouble; gentle slopes sit well inside that. |
| Steep / hilly | DependsThe snow rating stops at 36 percent, about 20 degrees. A steeper drive is outside the stated limit. | DependsThe published 70 percent slope rating is a manufacturer figure, untested independently, on a platform with documented boundary drift under canopy. |
| Jobs you need done | ||
| Snow clearingthey differ | GoodThis bundle is the Core with the snow blower module: a 24 in clearing width and a 12 in intake. | DependsThe Core takes a snow blower module. This record's specs cover the mower module, so clearing figures are not verified. |
| Lawn mowingthey differ | DependsNo mowing deck in this bundle. The Lawn Mower Pro module is sold separately. | GoodFitted with the mower module: a floating deck of two five-blade discs, 20 in wide. |
| Both, year round | DependsYear-round use means buying the Lawn Mower Pro module as well and swapping modules by season. | DependsYear-round use means swapping modules by season. Owner reports describe the motor cutting out in wet snow. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.

What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Yarbo Y40P Core Snow Blower
Hub motors and a larger area rating arrive with a list price $1,600 above the Y40 bundle.
This record holds no independent test of this Core. The maker set its launch for September 28, 2026.
No perimeter wire and no rooftop antenna, but positioning depends on a network connection.
Yarbo S1
Level III autonomy within each mode, but transitions between modes are entirely manual: the multi-function promise and multi-function execution are owned by different parties.
GPS precision eliminates wire installation on large lots, yet that same GPS dependency becomes liability when tree canopy or signal interference compresses effective coverage below property footprint.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Yarbo Y40P Core Snow Blower
- Buyers who want a winter of field reports first
- The maker set the launch of this Core for September 28, 2026, and shipping is estimated for October. This record holds no owner report and no independent test of it. Reliability, clearing quality and recovery from jams are unverified.
- Storms that drop more than 12 inches
- The intake is 12 inches high, and the maker's rating covers snow up to that depth. A deeper fall has to be cleared in passes during the storm. Regions with heavy single storms sit at the edge of the rating.
- Buyers weighing it against the Y40 bundle
- The sibling Y40 bundle carries the same snow module at a list price $1,600 lower. This Core adds hub motors and a rating of 7,000 square feet per charge against 6,000. This record holds no independent measurement of the difference.
- Buyers who want a general retailer
- The bundle is sold only through the maker's own store. This record found no listing at a general retailer. The warranty and return terms on this bundle's own page were not read for this record.
- Properties with weak outdoor connectivity
- Scheduling, zone mapping and the live camera view run through the app. Positioning relies on a network correction service. Whether the robot can finish a run during an internet outage is Not verified.
- Buyers wary of connected yard cameras
- The Core navigates with stereo cameras, and the app offers a live view. A June 2026 federal security advisory covered the maker's app and cloud service, and a fixed app version followed. How camera footage is stored is Not verified.
Yarbo S1
- Buyers expecting fully automated multi-task switching
- Module changes are made by hand. Yarbo states the change is tool-free and takes under two minutes, but the machine does not select or swap its own modules.
- Owners with heavily wooded or obstructed properties
- RTK-GNSS boundary accuracy depends on clear sky view for both the Core and the Data Center. Dense tree canopy is documented in owner reports as a recurring source of boundary drift.
- Buyers seeking snow clearing in wet heavy conditions
- Yarbo publishes a 12 in intake height and no wet-snow rating. Owner reports describe motor strain and incomplete clearing in heavy wet snow, so properties with frequent wet snowfall may encounter more edge-case failures.
- Tight lots with no safe discharge target
- The S1 is a two-stage blower with an adjustable throw of 6 to 40 feet. Properties where every discharge direction points at a walkway, a vehicle, a window, or a neighboring lot leave little room to aim it.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Yarbo Y40P Core Snow Blower
- After every use: Clear packed snow from the tracks and chute before the machine docks.
- Weekly: Check the tracks for packed ice during storm weeks.
- Monthly: Check that the docking station is clear of drifted snow and ice.
- As needed: Replace a shear pin and cotter pin after the auger strikes a hard object. The maker sells a set of 8 for $29.
- As needed: Re-map zones in the app whenever a driveway or walkway boundary changes.
- Seasonally: Detach the snow module once winter ends. Clean and dry it before off-season storage.
- Annually: Inspect the steel chute and auger drive for wear ahead of the winter season.
Yarbo S1
- After every use: Clear packed snow and debris from the auger housing and chute, or from the mower deck, with the machine powered down; inspect module drive components.
- Weekly (mowing season): Clean mower deck underside; check blade condition for nicks.
- Monthly: Inspect RTK-GNSS antenna housings for moisture; clean charging contacts on the docking station.
- Every 3-6 months: Sharpen or replace mower blades ($15-$30); inspect the auger and impeller for wear through the snow season.
- Annually: Battery capacity check; full module inspection before seasonal transition; firmware update review.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| Yarbo Y40P Core Snow Blower | Provisional | 19 | Oct 2026 |
| Yarbo S1 | Verified | 13 | Sep 2026 |
Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
