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 wire-free models in 2026: the Revola X4e (up to 1/2 acre, RTK-GPS + LiDAR, $799) and the NX100i (up to 1/4-1/3 acre, GPS-based navigation, $799, sometimes discounted to $699.99 at Tractor Supply). Both undercut comparable wire-free mowers from Segway or Mammotion by hundreds of dollars, but neither publishes a slope rating, and independent reviews flag spotty customer service — making Yard Force a budget bet rather than a safe default.
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 with genuinely wire-free hardware at a price that beats most of the category — but it’s also 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 | Price |
|---|---|---|---|---|---|
| Yard Force NX100i | Smallest lawns / entry price | 1/4–1/3 acre | 7 in | GPS-based (wire-free) | $799 ($699.99 at Tractor Supply) |
| Yard Force Revola X4e | Best overall / mid-size lawns | 1/2 acre | 8.7 in | RTK-GPS + LiDAR (wire-free) | $799 |
Confirmed 2026 pricing comes straight from yardforceusa.com, where both models list at $799 despite covering different yard sizes — the Revola X4e’s added LiDAR sensor and larger coverage make it the better value of the two at the same price point.
1. Yard Force Revola X4e — Best Overall
Yard Force Revola X4e
- Covers up to 1/2 acre using RTK-GPS combined with LiDAR for wire-free mapping — no perimeter wire to bury.
- 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.
- No published slope rating — a gap worth calling out compared to established brands that publish a specific grade percentage.
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 interesting of the two models: RTK-GPS plus LiDAR is the same sensor combination used by pricier flagships from Ecovacs and Mammotion, packed into a $799 mower. The catch is the missing slope spec — without a published grade rating, a sloped or uneven lawn is a gamble rather than a documented capability. For a flat 1/2-acre lot, 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.
- GPS-based wire-free navigation with Yard Force's Active Safety Navigation obstacle handling.
- 28V battery, roughly 29.3 lbs, CloudHawk app and WiFi/Bluetooth control.
- Priced identically to the larger, better-equipped 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, neither model publishes a slope rating — every established brand in this category lists a specific grade percentage or degree ceiling (Husqvarna’s iQ line up to 70%, Mammotion’s Luba 3 up to 80%/38.6°), and the absence of that number on Yard Force’s spec sheets means buyers on anything but a flat lawn are flying blind. 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.

Yard Force by the numbers
- $799: The US list price for both current Yard Force models, the Revola X4e and NX100i, per yardforceusa.com.
- ~2016: The year Yard Force added robot mowers to its outdoor power equipment lineup, roughly two decades after Husqvarna’s 1995 debut.
- 1/2 acre: Max coverage for the flagship Revola X4e, the larger of Yard Force’s two current US models.
- 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, wire-free robot mower brand you can actually buy in the US in 2026 — not a knockoff and not an EU-only tease. The Revola X4e packs RTK-GPS and LiDAR into a $799 mower, which is a genuinely competitive spec-to-price ratio. What holds it back from a stronger recommendation is the missing slope rating and reviews pointing to thinner customer support than category leaders. Buy Yard Force if your lawn is flat and the price is the deciding factor; if you want a slope spec you can plan around and a longer support track record, start with our best robot lawn mower pillar instead.
