Yarbo Y40P vs Y40 vs M20i: which fits your yard?
Full specifications18 measurements · 44 of 54 documented
What size yard is each one built to clear?
Each model states the ground it is rated for, from square feet per charge to the acreage range a whole module line targets.
Yarbo Y40P Core Snow Blower
Yarbo Y40 Snow Blower
Yarbo M20iYarbo's own specification wiki and the Y40P and Y40 product pages state the area-per-charge and weight figures used here; the M-series' 0.25-1.5 acre target comes from the manufacturer's Kickstarter page and matching trade-show coverage.
Trade-show coverage of the CES 2026 launch described the M-series as built for yards from a quarter acre to about 1.5 acres, distinct from the larger-property Core and Y-series line this comparison's other two machines belong to.
Which of the three can you buy right now?
Availability differs more than specs do: one ships from a single storefront, one also sits on a general retailer, and one is still a crowdfunding reward.
Yarbo Y40P Core Snow BlowerYarbo Y40 Snow BlowerYarbo M20iYarbo's own Y40 product page and its Amazon listing, sold by the maker under ASIN B0HJRC5RNC, both list current stock and pricing; the Y40P Core page and the Kickstarter M-series campaign page show no equivalent general-retail listing.
A crowdfunding risk analysis of the M-series campaign flagged the post-funding snow-module redesign and schedule slip as open questions for backers, who hold Kickstarter reward terms rather than a standard retail return window.
How does each one sense and navigate the yard?
All three skip a buried wire for network-corrected GPS, but the sensors layered on top of that baseline are not identical.
Yarbo Y40P Core Snow BlowerYarbo Y40 Snow BlowerYarbo M20iYarbo's NetRTK explainer and its product pages describe network-corrected positioning with stereo cameras on the Y40 and Y40P; CES 2026 coverage reported 360-degree LiDAR as the feature distinguishing the M20i from the M10 and M20.
What does the snow-clearing hardware itself do?
Clearing width, intake height and throw distance come from the snow module bolted onto each Core, and the three modules are not identical.
Yarbo Y40P Core Snow BlowerYarbo Y40 Snow BlowerYarbo M20iYarbo's Y40 and Y40P product pages list matching clearing width, intake height and throw-distance figures for the Gen 2 module on both machines; neither page states a figure for the M-series' redesigned module.
Yarbo's own project update to Kickstarter backers said the original plow blade was replaced with a two-stage blower in July 2026, calling the heavier module a new mounting, power-draw and balance validation on the Core.
What independent evidence exists on any of these machines?
Each record traces to a different mix of vendor material, past-generation reviews and a security advisory, and none of it is a test of this exact unit.
Yarbo Y40P Core Snow BlowerYarbo Y40 Snow BlowerYarbo M20iA long-term owner account of Yarbo's earlier Core documented two failed units, including one blown power board, and the maker's security notice alongside a federal advisory covered a credential flaw in the shared app and cloud service.
No published source in this record ties an independent test to the current Y40, Y40P or M20i hardware; earlier reviews of prior Core generations and snow attachments are listed but not counted toward these three machines.
In closing
What the evidence shows
Patterns that emerged across the questions above.
Area ratings scale with price, not test data
The higher-priced Y40P claims 1,000 more square feet per charge than the Y40, and both figures come from the maker; neither has an independent measurement behind it yet.
Purchase readiness splits the three machines unevenly
The Y40 sells through the maker's store and Amazon today, the Y40P sells only through the maker's store, and the M20i remains a Kickstarter reward with no retail listing yet.
Only the M20i adds LiDAR and a pre-release framework
The M20i is the only one of the three with 360-degree LiDAR and the only one scored under a pre-release framework instead of the consumer rubric the other two carry unevidenced.
