Reference Price
The Core base unit alone lists at $3,999 (0% APR financing advertised at ~$333/mo), consistent across yarbo.com and third-party retailers. Individual attachment modules are sold separately — Lawn Mower Pro ~$2,000, Snow Blower Gen 2 ~$2,200, leaf Blower ~$1,100, Trimmer package ~$1,300 — so a real-world working setup (Core plus one or more modules) typically runs $6,000–$8,000 per reviewer estimates, well above the base sticker price. Core is listed in stock on yarbo.com, with an estimated delivery of 3–8 business days as of this writing.
Sensors & Hardware
"Core" is the Y40 base chassis — tracked drive, motor, battery, navigation computer, sensors — needing a quick-swap module to work. Navigation combines RTK-GPS, stereo vision, IMU, and odometry via a local RTK base station, plus six HD cameras and ultrasonic radar. Tom's Guide praised cut quality and obstacle avoidance but found setup took "an entire weekend."
Insights
Yarbo presents itself as a Ronkonkoma, New York-based company, but independent reporting from Cybernews found it's tied to Shenzhen-based Hanyang Tech, China. That same reporting disclosed a security/backdoor flaw in Yarbo's product line — worth knowing for anyone evaluating the brand's data-privacy posture, separate from how well the hardware itself performs.
Firmware & Community
Closed platform — SDK planned
Yarbo has announced an "Open Platform" strategy with a planned SDK and API, but as of this writing that program is not yet released (targeted for early 2027) and Yarbo has not released a public SDK, firmware repo, or developer API for Core. Not currently listed in Builds & Mods.
Verified against Yarbo's own official site (yarbo.com) and Kickstarter/funding coverage (PR Newswire), plus an independent Tom's Guide hands-on review. Physical dimensions, weight, battery voltage, and a dB noise rating were not confirmed from accessible official sources and are marked as unpublished rather than estimated. Cybernews' independent reporting on the company's actual China ties (via Hanyang Tech, Shenzhen) and a disclosed security/backdoor flaw is included because it materially affects how the brand should be evaluated, separate from hardware performance. Do not confuse this Y-series "Core" with Yarbo's separate, newer "M Series," which launched its own crowdfunding campaign with different pricing.
