Mammotion Yuka

The Yuka mini is the cheapest way into a wire-free, station-free robot mower from a brand with a real support desk, and at $749 for the 600H (or about $949 for the 800H at Home Depot) it undercuts the Navimow i105 while still carrying a 3-year warranty. There is no RTK antenna: it pulls free NetRTK corrections over your Wi-Fi and leans on two front cameras to track the grass edge, which is why it auto-maps a small yard in ten minutes. It is a 23 pound, rear-drive machine with a 7.5 inch disc and a 2.0 to 3.5 inch cut, rated for 50 percent slopes, though owners with bumpy or sloped yards say the front caster and lift sensor trip constantly and they end up rescuing it. On flat lawns under a fifth of an acre owners are happy: quiet, tidy stripes, and they like that it stays in bounds even where GPS is weak. Weak points are an app that lacks polish, cautious behavior around tree trunks that leaves rings of long grass, no built-in 4G (a $129 module adds it) and a 2 inch minimum height that rules out a tight cut. Mammotion has since released the LiDAR Yuka mini 2 at $1,399, so this is the value play. Best for flat, simple yards up to 0.2 acres and first-time robot owners.

Best for Flat suburban yards up to a fifth of an acre where a cheap, station-free mower with real warranty support is the goal.

The Luba 2 AWD X is the mower that made Mammotion a household name in the US, and in fall 2026 it is a clearance buy: Mammotion's own store shows every trim out of stock with a banner pointing at the Luba 3, but Home Depot and Best Buy still have units, with the 3000X down from $2,599 to about $1,999. What you get is the same all-wheel-drive body that climbs 80 percent grades, a 15.7 inch dual-disc deck that clears a big yard fast, and a 2025 X refresh that added the UltraSense AI camera so it keeps its bearings when the RTK station loses sky. The catch is that RTK station: it must be mounted high with an open view, and most owner complaints trace back to a poorly placed antenna. The X version cuts 1.0 to 2.7 inches, so northern cool-season lawns should look for the HX (2.2 to 4.0 inches) instead. Versus the newer Luba 3 you give up LiDAR and free NetRTK, which matters if your lawn is ringed by trees; versus a Segway Navimow X3 you gain real AWD and a wider deck. Best for hilly half-acre to 2.5 acre properties with decent sky, bought on discount.

Best for Big, hilly lawns with open sky where a discounted last-generation AWD mower beats paying full price for the Luba 3.

The YUKA mini 2 1000H is a different machine from the first-gen Yuka mini even though the body looks alike: the NetRTK-plus-camera setup is gone, replaced by a spinning 360 degree LiDAR puck with a 60 m range, two AI cameras and a 10 TOPS chip. That is why it costs $1,399 (list $1,559) against $749 for the original, and why it suits a different lawn. The first-gen unit leans on satellite corrections and wanders under trees and along fences; reviewers ran the mini 2 down a narrow fenced path with tree cover and it tracked straight with no drift, then cut so close to a stone border that almost nothing was left to trim. Otherwise it is a small rear-drive mower: a 7.5 inch disc with five pivoting blades, a 2.0 to 3.5 inch cut on the H version, 45 percent slopes, a 6.1 Ah battery good for about 2.5 hours and 2,690 sq ft per charge, and a 0.25 acre ceiling. Testers watched it slow for a football and steer around a glove lying flat, and it remembers strips it skipped and comes back. The knocks are minor but real: cut height is a manual dial rather than per-zone in the app, the 4G module is a separate purchase, added areas cannot be auto-mapped, and it was sold out on Mammotion's US store in late September 2026 while Amazon and Home Depot still stocked it. Next to the Sunseeker S4, the other quarter-acre LiDAR mower near this price, the Mammotion buys a longer LiDAR range and a 3-year warranty.

Best for Quarter-acre yards with tree cover, tall fences or several zones linked by narrow paths where a satellite-guided mower loses its place.

Think of the Luba mini 2 AWD as the Luba 3's tech shrunk to fit a third-acre suburban lot. It replaced the original Luba mini AWD in spring 2026 (that one is now out of stock at Mammotion) and swapped NetRTK-only positioning for a 360-degree LiDAR dome plus two AI cameras, so it no longer cares whether your yard has open sky. It keeps the four hub motors that let it climb 80 percent grades, and it adds something the big Lubas lack: a second, fixed 4.7 inch edge disc that trims within about 2 inches of walls and beds, which owners say cut their string-trimmer time way down. The main deck is only 7.8 inches, so it is slower per pass than a Luba 3, but 150 minutes of runtime covers a 0.37 acre lawn in a session or two. Owners who came from wire mowers rave about the setup and the finish, and the complaints are the fixed 2.6 inch height of the edge disc, a learning curve on multi-zone mapping, and wheels that occasionally spin on a wet hill. In the US only the 1500 size is sold, with the H version (2.2 to 4.0 inch cut) at $1,699 on sale. Compared with a Segway Navimow i110 you pay more but get AWD and LiDAR; compared with a Yuka mini 2 you get hill-climbing traction. Best for hilly, obstacle-heavy yards up to 0.37 acres.

Best for Small to mid-size yards with steep spots, tree cover and lots of beds where a compact AWD mower with an edge disc pays off.

The Luba 3 AWD is Mammotion's 2026 flagship and the mower that finally fixed the Luba's biggest headache: there is no RTK antenna to mount. It positions with a 360-degree LiDAR dome, two AI cameras and free NetRTK corrections pulled over Wi-Fi or its built-in 4G, and owners on wooded lots say it maps and mows under tree cover where the Luba 2 used to wander. The rest is familiar Luba: four hub motors and omni wheels that climb 80 percent slopes, a 15.7 inch dual-disc deck with 165 W motors on the 3000 and 5000, and up to 50 zones. The 3000 is the sweet spot at $2,109 on sale (it is oddly cheaper than the 1500), and it comes in a 2.2 to 4.0 inch high-cut or 1.0 to 2.7 inch standard deck. Owners praise the setup and the app, and the common gripes are learning menus that keep changing with OTA updates, a 1.25 acre map cap on the 5000, and the occasional unit that dies after a firmware push with slow support. Against the Roborock RockMow X1 LiDAR it costs less and cuts wider; against a Husqvarna 450X NERA it is a fraction of the price with no dealer install. Best for half-acre and larger lawns with hills, trees and several zones.

Best for Half-acre to 1.25 acre lawns with slopes, tree cover and multiple zones where a station-free LiDAR mower earns its price.

Greenworks retired the wired Optimow line for consumers in 2026 and replaced it with AiMowbot, and the C30Z is the 3/4-acre model in the front-wheel-drive C series. It uses what Greenworks calls RTKVision 2.0: an RTK reference antenna kit in the box for roughly 1 in positioning, with cameras and night-vision sensors that help it hold its line under trees and spot 200-plus obstacle types. Mowing zones, paths and no-go areas are drawn in the app; there is no wire to bury. The spec sheet is strong for $1,599.99: 45% (24 degree) slopes, an electric height adjuster from 0.75 to 3.5 in, a 54 dB noise rating, IPX6 washdown, LED headlights and a 50-minute charge. It is a front-wheel-drive three-wheeler, so it is not a Luba-style AWD climber, and the 8 in cut is narrower than a Mammotion Yuka's. Two things to weigh before buying: 4G and anti-theft tracking need a subscription Greenworks has not priced publicly, and edge cutting is rated at 4 in from the border, so keep the string trimmer. The 1/2-acre C20 ($999.99) and 1-acre C40 ($1,499.99) are the siblings and the G series adds AWD. It is a 2026 launch with no owner track record yet, which is worth remembering given how much grief the old Optimow app caused. Best for 1/2- to 3/4-acre yards with moderate slopes and a buyer who wants a 3-year warranty behind a wire-free mower.

Best for Half- to three-quarter-acre yards with some slope whose owner wants a current-generation wire-free mower from a big-box brand.
