A $50 pass just unlocked real savings on Yarbo's biggest yard robot yet, and the math works out a little differently depending which side of the border you're on. Yarbo's Y40P Core, the high-performance version of its modular yard robot, launched September 15, and its Early Access window runs through September 28 in both the US and Canada.
What's new

Yarbo's Y40P Core swaps in a Dual Hub Motor Drive System, pushing top speed to 1.2 m/s and adding stronger traction on hills compared to the standard Y40. Yarbo rates it for slopes up to 35 degrees (a 70 percent grade) while mowing and 20 degrees (36 percent) while running the snow blower attachment, with coverage for up to 7 acres of mowing a week.
To mark the launch, Yarbo is selling a $50 Early Access Pass, in USD or CAD depending on your storefront, through September 28. Buying it locks in Early Bird pricing and adds an extra discount on top, though the size of that discount differs by region.
Why it matters

Yarbo's been splitting its lineup by yard size this year. A smaller, cheaper M Series showed up at IFA Berlin earlier this month for standard properties, and the Y40P Core is the sibling built for people with acreage and hills to spare.
The pricing window matters just as much as the product here. After September 28, the Early Access Pass and its extra discount disappear, and Early Bird pricing becomes the best rate left on the table in either country.
Key details

US pricing (USD), Early Access through September 28:
- Y40P Core only: $4,999 (Public Early Bird $5,199, MSRP $5,599)
- Y40P Core + Lawn Mower Pro + Snow Blower Gen 2: $8,999 (Public Early Bird $9,199, MSRP $9,799)
- Y40P Core + Snow Blower Gen 2: $7,099 (Public Early Bird $7,299, MSRP $7,799)
- Y40P Core + Lawn Mower Pro: $6,899 (Public Early Bird $7,099, MSRP $7,599)
That works out to a net $150 in savings once the $50 pass is factored in.
Canada pricing (CAD), Early Access through September 28:
- Y40P Core only: C$6,999 (Public Early Bird C$7,249, MSRP C$7,699)
- Y40P Core + Lawn Mower Pro + Snow Blower Gen 2: C$12,549 (Public Early Bird C$12,799, MSRP C$13,499)
- Y40P Core + Snow Blower Gen 2: C$9,899 (Public Early Bird C$10,149, MSRP C$10,699)
- Y40P Core + Lawn Mower Pro: C$9,699 (Public Early Bird C$9,949, MSRP C$10,499)
That works out to a net C$200 in savings once the C$50 pass is factored in.
Starting September 29, the Early Access Pass and its extra discount go away in both regions, and Early Bird pricing becomes the best rate left.
Takeaway
On paper, the Y40P Core is Yarbo's answer for yards the standard model can't keep up with, and the extra traction and speed matter if you've got real acreage and actual slopes to deal with. If you were already sold on the Y Series, the math is simple either way: pay $50 now, net $150 back in the US or C$200 back in Canada, before September 28.
It'll be worth seeing how the Dual Hub Motor Drive System and those slope ratings hold up once real owners get their hands on it, since all of this comes from Yarbo's own specs for now. Anyone with a smaller, flatter yard should look at the cheaper M Series instead. This one's built for people with room to spare.
