Anthbot N8

The M9 is the M5 body with a 5 Ah, 90 Wh battery, rated for 1,000 m2 (about a quarter acre) and sold direct for $699 against an $899 list, or $769 with a garage. Positioning is full-band RTK from an included reference station plus dual 150-degree HDR cameras, with NetRTK over the built-in 4G as an option, so there is no wire and setup takes about ten minutes. It cuts with a 7.9 inch five-blade disc at 1.2 to 2.8 inches, climbs 45 percent, runs about 90 minutes per charge and recharges in 90 more, weighs 22.5 lb, and stays under 58 dB. Two independent hands-on reviews were positive: one had it navigate an L-shaped lawn with clothesline poles cleanly and leave neat U-pattern stripes on uneven ground, the other watched it finish about 80 percent of a yard in 77 minutes while steering around dog holes and shrubs, and both praised the beginner-friendly app. The gripes are the 2.8 inch maximum height, lower than the 3.5 inches a Navimow allows, occasional false stops for shadows, and a remap if the first auto-map comes out loose. Against the Segway Navimow i110N ($929, same quarter acre) it is $230 cheaper, includes 4G and a rain sensor and cuts wider; the Mammotion Yuka mini ($749) is the closer fight, and the M9 is rated for more ground.

Best for Flat or gently rolling quarter-acre lawns for first-time robot owners who want RTK precision and 4G for under $700.

The M5 is the entry point to Anthbot's 2026 M series, a compact wire-free mower rated for 500 m2 (about 1/8 acre) that anthbot.com sells for $649 against a $799 list, or $679 with a garage. It uses the same full-band RTK receiver and two 150-degree HDR cameras as the M9, and the cameras run visual odometry so it keeps mowing when a house or tree blocks the satellite view; a 4G module is built in with no subscription, and NetRTK positioning (no base station) comes as a three-month trial. The deck is a 7.9 inch five-blade disc with 1.2 to 2.8 inch app-set height, it climbs 45 percent, mows about 150 m2 an hour at 58 dB, and rain sensing sends it home. Reviewers who ran one found setup and mapping the easy part and cut quality fine on maintained grass, but reported missed slivers along edges, slower edge passes, and a mower that struggles once grass is overgrown or the layout gets intricate. Runtime and weight are not published. Against the Segway Navimow i105N ($799, 0.12 acre) it costs $150 less and adds 4G and a rain sensor; against Anthbot's own Genie 600e it trades the four-camera array for a newer body with on-edge mowing.

Best for Small, flat, simply shaped lawns up to about 1/8 acre where a $650 wire-free mower only has to keep grass short.

The Anthbot Genie started as a Kickstarter in 2024 and has settled into the role of the budget RTK mower that actually works on a plain lawn. In fall 2026 Anthbot sells the 600e for $699, the 1000 for $799 and the 3000 for $899 direct, which is less than half of what Mammotion or Roborock charge for similar coverage, and the 3000 is rated for up to 0.89 acres. The hardware is modest: a 7.9 inch disc, 1.2 to 2.8 inch app-set height, rear-wheel drive and a 45 percent slope rating, but the 10 Ah battery in the 3000 runs about four hours, it is one of the quietest mowers at 58 dB, and an included RTK antenna plus four cameras handle positioning and obstacles. Owners who set the antenna in open sky say mapping was easy, the stripes look professional and it handles multiple zones well; the negative reviews are the flip side, describing RTK dropouts near houses, a stubborn firmware update at first setup, over-cautious stops for leaves, and a unit that degraded badly in its second season with slow support. The narrow deck means a large yard takes two passes to look finished. It competes with the Navimow i105 on price while covering far more ground, and the Yuka mini beats it on setup simplicity. Best for budget buyers with flat, open lawns up to three-quarters of an acre.

Best for Budget shoppers with flat, open lawns up to three-quarters of an acre who want RTK precision without a $2,000 price tag.

The M5 LiDAR is the 500 m2 M5 body with the RTK receiver swapped for a 360-degree LiDAR dome on top, priced at $799 direct against $949 list. With no reference station to mount and no satellite fix to wait for, it maps by auto-mapping or driving the perimeter and holds position under trees and against walls where the RTK M5 needs open sky. It keeps the dual 150-degree HDR cameras for obstacle recognition, the 7.9 inch five-blade disc, 1.2 to 2.8 inch app height, 45 percent slope rating, 58 dB noise, rain sensing and IPX6 washdown. The trade-offs are real: the 2.5 Ah battery gives roughly 40 minutes per charge with a 60 minute recharge, and one hands-on test found the LiDAR track snakes slightly more than RTK through narrow passages and hesitates at high-contrast surface changes, while still scoring it 85/100 for mapping speed, edge tuning and moving between zones through gaps and ramps. 4G remote access is paid after the trial. Weight is not published and only two reviews sit on the product page. The cataloged rival is the Ecovacs Goat O1000 LiDAR Pro at $1,499 for a quarter acre; the M5 LiDAR halves the price for half the area, so it suits small, enclosed, tree-shaded lawns better than the RTK M5 does.

Best for Small, enclosed lawns up to 1/8 acre with tree cover, walls or narrow side passages that would starve an RTK antenna.

The X5 is the middle of Sunseeker's AWD range and an online-only model: a 0.5 acre rating, four driven wheels on off-road tires with a 60% slope rating, an 8.6 in floating deck adjustable from 1.6 to 3.2 in, and AONavi Pro navigation that fuses an included RTK base station (it needs a spot with open sky) with twin V-SLAM cameras so it keeps its line when trees block satellites. Sunseeker sells it for $1,499 against a $1,999.99 list, with 100 zones, corridors, no-go areas, a rain sensor and an offset blade that trims to within 1.2 in of fences. Sunseeker does not publish runtime, charge time or weight for the US model; an EU-spec review cites a 5Ah pack and 60 dB. That reviewer, on an uneven garden with obstacles placed on purpose, found the suspension and AWD handled the bumps, the binocular cameras avoided everything set out, and the app was simple, but needed three app updates before Bluetooth setup behaved. Store owners on sloped half-acres describe straight stripes and the edge blade taking over fence lines and driveways, and name the step-by-step setup and RTK firmware updates as the main friction. For the same $1,500 the Roborock RockMow X1 claims a full acre and 80% slopes with a wider 9.5 in deck, so the X5's case rests on its edge blade and Sunseeker's US support rather than raw numbers.

Best for Sloped half-acre suburban yards with fences and a driveway to edge, for buyers who want AWD traction at a mid-range 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.
