Robomow RK2000

The Landroid L is the half-acre version of the Worx wired platform: same chassis logic as the M, a wider 8 in blade disc and a bigger 5.0Ah (some kits ship 6.0Ah) 20V Power Share pack that swaps into any Worx tool. Worx lists it at $1,499.99 but it has been sitting near $1,000 on Amazon and under $750 at Walmart, which makes it the cheapest half-acre robot from a brand with a US support line. Expect four to six hours laying the 820 ft of included wire. In use it is a bump-and-turn random mower with Cut to Edge, a floating blade disc that copes with lumpy ground, a rain delay, and a 30% slope rating that reviewers flag as the lowest in its class, so skip it on rolling terrain. Reviewers report roughly an hour of mowing per charge, so a full half acre means several dock trips a day and a schedule that runs most days. Obstacle avoidance is a bumper unless you add the ACS ultrasonic kit. Compared with a Husqvarna Automower 415X you give up polish and dealer support for roughly half the price; compared with a Segway Navimow at similar coverage you keep the wire but keep $700 in your pocket. Best for budget-minded owners of flat, open half-acre lawns who would rather spend a Saturday pegging wire than pay for RTK.

The Optimow 33H is Greenworks' one-third-acre boundary-wire mower, now sold through the Greenworks Commercial dealer network rather than big-box stores; the online store lists it at $1,099.99 and sold out, so a local dealer is the realistic route. The H means high cut, 2.4 to 4.0 in, which suits fescue and Kentucky bluegrass lawns that the 0.8 to 2.4 in Optimow 33 would scalp. Mechanically it is a conventional Husqvarna-style platform: boundary wire plus guide wires, a random bounce pattern, three pivoting razor blades on an 8.7 in disc, a 24V battery, 130-minute recharge, IPX5 washdown and a 19 degree (about 34%) slope rating. Its differentiator is built-in 4G with GPS: the GreenGuide app works from anywhere and the mower can be tracked if it walks off. Owners of the sibling Optimow 50H on Best Buy like the cut but call the app frustrating, and the cellular plan is only prepaid for two years before an annual fee kicks in. There is no edge-cut mode and no camera, so it bumps its way around obstacles. Against a Husqvarna Automower 310 Mark II it is cheaper with a longer warranty, but dealer-only availability and the app complaints keep it from being an easy pick. Best for a flat to gently sloped third-acre lawn within reach of a Greenworks dealer.

The 415X was Husqvarna's small-yard X-line mower before the iQ series, and it is still sold through the Husqvarna shop and dealers at $2,000 even though the product page says discontinued. You get the premium X-line touches - LED headlights, app-adjusted electric cut height, GPS theft tracking and built-in cellular - in a 21-pound body rated for 0.37 acres and 40 percent slopes. The cut range of 0.8 to 2 inches suits warm-season grasses and tidy, short lawns, not tall fescue. It runs on a boundary wire with guide wires and a systematic passage mode, and the 50-minute runtime with a 60-minute charge means it cycles often. Owners say it just works once the wire is in, and that install takes about half a day if you watch the videos first; the complaints are about durability, with a warped cutting disk, wheels lost to surfacing rocks, and mowers that would not wake up after winter, plus customer service that punts to dealers. At 62 dB it is noticeably louder than a Navimow i110N, and a Segway or Mammotion at this price is wire-free with cameras. Choose it for a small, wire-friendly yard where you want Husqvarna dealer support and a short, even cut.

The Landroid M is Worx's quarter-acre boundary-wire mower and, thanks to the 20V Power Share battery it shares with every other Worx tool, it is usually one of the cheapest ways into robot mowing that still comes with a real app. Worx lists it at $1,199.99, but it sells for around $900 on Amazon and Walmart has been clearing it below $800, so shop around. Setup is the classic wire job: 820 feet of wire and 340 pegs are in the box, and plan on an afternoon of pegging. Once running, the AIA algorithm handles narrow passages without a guide wire, the off-center blade genuinely cuts to the edge, the floating blade disc lifts over bumps, and at 59 dB it is quiet enough to run at night. The catch is what it lacks: no camera or ultrasonic sensor in the box, so it bumps into anything the wire does not exclude, and there is no GPS tracking unless you buy the Find My Landroid module. Against the Gardena SILENO flex at $599 you pay more for a 3.5 in top cut height and Wi-Fi control; against the wire-free Landroid Vision you save several hundred dollars but do the wire work yourself. Best for flat, fairly open yards under a quarter acre owned by someone who already has Worx batteries in the garage.

STIHL's iMOW EVO line replaced the old Viking-era iMOWs in Europe in 2023 and reached US dealers in 2024, and the 5 EVO is the smallest of the three (the 5, 6 and 7 EVO cover roughly 0.37, 0.74 and 1.25 acres). It is a boundary-wire mower, so someone has to lay perimeter and guide wire, but once that is done it is one of the more polished wire machines around: an 11-inch disc with three free-swinging blades, electric height adjustment from 0.8 to 2.4 inches, 45 percent slopes (55 with the optional Kit 10 wheels), ultrasonic sensors that slow it before it bumps anything, a rain sensor you can tune, and a mobile network module built in so the MY iMOW app works away from home. It is quiet (61 dB sound power, 48 dB pressure) and light at 33 pounds. T3's reviewer called it outstanding on cut quality but was annoyed by app logouts and by its inability to cut flush to raised edges, a limit of any wire mower. Runtime is short, 65 minutes per charge with a 140-minute full recharge, though STIHL rates it for 1,500 square meters over a week of cycles. At about $2,530 through STIHL dealers and Ace, it costs more than a wire-free Segway Navimow i110 that covers the same area with no wire, so the case for it is dealer install, dealer service and STIHL build quality rather than technology. Best for someone who already has a STIHL dealer they trust and does not want to fuss with RTK antennas.

The 115H 4G is Husqvarna's budget Automower and, at the $300 the brand and its dealers have been selling it for through 2026, an easy way to try robot mowing without a big bet. It is old-school: you bury a boundary wire and one guide wire, it bounces randomly around up to 0.4 acres, and it cuts high at 2 to 3.6 inches, which makes it a better match for fescue and bluegrass than most budget robots. The 4G module means the Automower Connect app works from anywhere, with no subscription for ten years. Owners are consistent about the tradeoffs: wire install takes a weekend, the wire will eventually get cut and you will want a toner, cut height is a manual dial, there is no GPS tracking, and a fair number report it stalling short of the dock. It has only a bumper, so pick up toys and sticks, and slopes top out around 30 percent. Against a Segway Navimow i105N or a Worx Landroid Vision, you give up wire-free setup and any real obstacle avoidance; what you keep is quiet 58 dB operation and Husqvarna dealer service. Right for a small, flat, fenced yard on a tight budget; wrong for anyone who hates the idea of wire.
