Quick Answer: Yard Force is a real, US-available robot mower brand owned by SUMEC Hardware & Tools (part of China’s Sinomach group), selling two boundary-wire models in 2026: the Revola X4e (up to 1/2 acre, 35% slope, $799) and the NX100i (up to 1/4-1/3 acre, 40% slope, $799, sometimes discounted to $699.99 at Tractor Supply). Both undercut wire-guided rivals like Robomow on price and add ultrasonic obstacle/lift/tilt sensors plus app control — but despite “advanced navigation” language on Yard Force’s own site, neither model is wire-free, and independent reviews flag spotty customer service.
Last updated September 2026: Re-verified specs directly against Yard Force’s own product pages and multiple retailer listings (Home Depot, Tractor Supply, Amazon, Walmart) — this review’s original claim that both models use wire-free RTK-GPS/LiDAR navigation was incorrect. Both the Revola X4e and NX100i are boundary-wire mowers with ultrasonic sensors; the corresponding claim that neither published a slope rating was also outdated — Yard Force now lists 35% (X4e) and 40% (NX100i) incline ratings. All sections below have been corrected accordingly.
If you’ve spotted the Yard Force name at Home Depot or Walmart and wondered whether it’s a legitimate robot mower brand or an off-brand gamble, the honest answer is a bit of both. It’s a real, currently-sold line at a price that beats most of the wire-guided category — but it’s a boundary-wire brand marketed with “advanced navigation” language that can read as wire-free at a glance, and it’s a newer, smaller operation than the Husqvarnas and Worxes of the world, and that shows up in the fine print.
Who actually makes Yard Force
Yard Force is owned by SUMEC Hardware & Tools Inc., a subsidiary of SUMEC Group under China National Machinery Industry Corporation (Sinomach), one of China’s large state-affiliated industrial conglomerates. The brand has sold outdoor power equipment — trimmers, blowers, pressure washers — since the mid-2000s, and added robot mowers to its lineup around 2016. That’s a very different pedigree from category originators like Husqvarna (1995) or Robomow (also 1995), but it means Yard Force isn’t a fly-by-night dropship brand either; it has real distribution through Home Depot, Lowe’s, Walmart, Tractor Supply, and Amazon in the US, per current retailer listings.
Yard Force 2026 US lineup at a glance
| Model | Best for | Max coverage | Cutting width | Navigation | Slope | Price |
|---|---|---|---|---|---|---|
| Yard Force NX100i | Smallest lawns / entry price | 1/4–1/3 acre | 7 in | Boundary wire + ultrasonic sensors | Up to 40% | $799 ($699.99 at Tractor Supply) |
| Yard Force Revola X4e | Best overall / mid-size lawns | 1/2 acre | 8.7 in | Boundary wire + ultrasonic sensors | Up to 35% | $799 |
Confirmed 2026 pricing comes straight from yardforceusa.com, where both models list at $799 despite covering different yard sizes — the Revola X4e’s larger coverage and slightly higher cutting width make it the better value of the two at the same price point. Both require the same buried boundary wire; neither is wire-free.
1. Yard Force Revola X4e — Best Overall
Yard Force Revola X4e
- Covers up to 1/2 acre using a buried boundary wire (800 ft wire, 300 pegs included) plus ultrasonic obstacle, lift, and tilt sensors — not wire-free, despite "advanced navigation" marketing language.
- 8.7-inch cutting width with 6 adjustable cutting heights, up to 2.4 inches.
- 28V brushless wheel motors, roughly 18.5 lbs, controlled through the CloudHawk WiFi app.
- Rated for inclines up to 35%, per Yard Force's own product page — a real, published spec as of this update.
Setting up a wire-free mower for the first mow of the season goes faster with the right accessories already on hand — try Amazon Prime free for 30 days and a replacement blade kit or extra charging pad from your Amazon cart arrives in two days instead of a week.
The Revola X4e is the more capable of the two models, with a wider cutting deck and a published 35% slope rating — but it’s a boundary-wire mower, not the RTK-GPS/LiDAR wire-free setup this review originally described. That means the same wire-trenching install as a Robomow, just with ultrasonic obstacle sensing and app control layered on top. For a buyer already fine with laying wire, it’s a legitimate value pick; compare it against our best budget robot lawn mower roundup before deciding.
2. Yard Force NX100i — Best Entry-Level
Yard Force NX100i
- Compact 7-inch cutting width for lawns up to 1/4 to 1/3 acre.
- Boundary-wire navigation (720 ft wire, 220 pegs included) with active ultrasonic obstacle, lift, and tilt sensors — not wire-free, though it is rated for inclines up to 40%.
- 28V battery, roughly 29.3 lbs, CloudHawk app and WiFi/Bluetooth control.
- Priced identically to the larger Revola X4e on Yard Force's own site — check Tractor Supply and other retailers for a discount before buying direct.
For a small townhouse lawn, the NX100i gets you wire-free navigation at the same price a boundary-wire competitor like Robomow’s entry-level RX20 charges — but since it lists at the same $799 as the larger, LiDAR-equipped Revola X4e on Yard Force’s own site, shop around first. See our best robot lawn mower for small yards guide for how it stacks up against other compact picks.
Where Yard Force falls short of the established brands
Two things separate Yard Force from category leaders like Husqvarna, Segway Navimow, or Mammotion. First, it’s a boundary-wire brand competing on a “advanced navigation” pitch — both models require the same buried-wire install as any traditional mower, while genuinely wire-free rivals like the Segway Navimow i105N ($799 MSRP) or Worx Landroid Vision skip the trenching entirely at a comparable price. Yard Force’s 35-40% slope ratings are real and published, but they’re well below AWD wire-free flagships like Mammotion’s Luba 3 (80%/38.6°) or Husqvarna’s iQ line (up to 70%). Second, independent reviews of the brand note inconsistent customer service and replacement-parts availability, and both models were still marked “Coming Soon” directly on yardforceusa.com even while already sold through Home Depot, Lowe’s, and other retailers — a sign of a smaller, less mature US operation than brands backed by Husqvarna Group or Stanley Black & Decker. If wire-free setup or long-term parts and support matter more than the sticker price, see our best robot lawn mower pillar for more established alternatives.
Yard Force by the numbers
- $799: The US list price for both current Yard Force models, the Revola X4e and NX100i, per yardforceusa.com.
- 35% / 40%: Published incline ratings for the Revola X4e and NX100i respectively — real, documented specs as of this September 2026 update, correcting this review’s original finding of no published slope rating.
- 800 ft / 720 ft: Boundary wire included with the Revola X4e and NX100i kits — both models require the same trenching install as a traditional wire-guided mower, not the wire-free setup this review originally described.
- ~2016: The year Yard Force added robot mowers to its outdoor power equipment lineup, roughly two decades after Husqvarna’s 1995 debut.
- 2-year: Yard Force’s US limited warranty on robot mowers, with a 90-day warranty on accessories and blades, per Home Depot’s published warranty documentation.
- 5 retailers: Yard Force robot mowers are currently listed at yardforceusa.com, Home Depot, Lowe’s, Walmart, and Tractor Supply — genuine multi-channel US distribution, unlike EU-only brands such as Bosch Indego.
The bottom line
Yard Force is a real, boundary-wire robot mower brand you can actually buy in the US in 2026 — not a knockoff and not an EU-only tease, but also not the wire-free bargain it can sound like at a glance. The Revola X4e packs ultrasonic obstacle sensing and a published 35% slope rating into a $799 mower, which is a fair price for a wire-guided machine with app control. What holds it back from a stronger recommendation is that a buried-wire install is still required, plus reviews pointing to thinner customer support than category leaders. Buy Yard Force if you’re comfortable laying boundary wire and the price is the deciding factor; if wire-free setup matters more, start with our best robot lawn mower pillar instead.
