Worx Landroid L WR155

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.

How it navigates

Perimeter boundary wire (820 ft and 340 pegs included); AIA pattern navigation gets through narrow passages without a guide wire; Wi-Fi and Bluetooth app with OTA updates, no GPS positioning.

Boundary-wire mower: budget an afternoon (or an installer) for the perimeter wire before the first mow.

Highlights

Pros

  • Lowest cost per acre of any name-brand half-acre robot, often near $1,000 or less
  • Widely stocked at big-box retailers, so returns and parts are easy
  • Floating blade disc self-levels over ruts and roots
  • Cut to Edge and rain delay are standard, not add-ons
  • Power Share battery doubles as a spare for other Worx tools

Cons

  • Roughly an hour per charge means a lot of dock trips on a full half acre
  • 30% slope rating is the weakest in its price class
  • No obstacle avoidance beyond the bumper without the ACS kit
  • Wire install is a real afternoon-plus job and wire breaks are on you

Pros and cons above are drawn from the manufacturer’s spec sheet and published reviews; this model is too new for a body of owner reports.

Worx Landroid M WR147
~$902
Boundary Wire

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.

Worx Landroid Vision AI WR208
from ~$1,349
Vision Only

Landroid Vision is Worx's answer to the boundary-wire chore: no wire, no RTK antenna, no mapping drive. You set the dock on the grass, press go, and a 140-degree HDR camera with an onboard neural net decides what is lawn and what is not, treating the edge of the grass as the boundary. The 1/5-acre WR208 is the entry model; the WR210 is the same 33 lb machine rated for a quarter acre at $1,999.99 list. Pricing is all over the place: Worx lists the WR208 at $1,599.99, Amazon has it around $1,350, and Target and Worx have run it at $799.99. In use it is quiet at 59 dB, cuts to the edge with an offset blade, and will stop for pets, toys and hoses lying on the ground. Reviewers found the downward-pointing camera misses things above its sightline (a parked trailer, a playground slide) and that it needs a visible edge: where lawn meets mulch or a neighbor's grass without a curb, you stake down the included magnetic strip. Separate lawns need RFID tags and usually a carry between them. Versus an Eufy E15 or Segway Navimow i105 at similar money this is simpler to install but less precise and it mows in a random pattern; versus Worx's newer Landroid Vision Cloud (RTK plus camera, $1,799.99) it gives up mapping and systematic rows. Best for small, well-defined lawns where nobody wants to bury wire or plant an antenna.

Worx Landroid Vision AI WR220
from ~$2,499
Vision Only

This is the bigger-lawn Vision, sold as the WR220 for half an acre with 3/4-acre (WR230) and 1-acre (WR235) siblings that share the same 33 lb body and 20V 4.0Ah pack and simply get longer daily schedules. List is a steep $2,499.99 to $3,499.99, and Worx has run the WR220 as low as about $1,100 during clearance, so watch for promos before paying full price. The pitch is identical to the smaller WR208: no wire, no RTK base station, no mapping session; the 140-degree HDR camera reads grass versus not-grass and treats that line as the boundary, while the same camera recognizes people, pets and objects on the ground and steers around them. It cuts to the edge with an off-center blade, has a rain sensor, and the optional Find My Landroid module adds 4G tracking. The compromises grow with the lawn: random-pattern mowing means it needs many more hours per week than an RTK mower to cover the same ground, split lawns still need RFID tags and a carry, and the camera struggles wherever there is no clear visual edge. For a half acre and up, a Mammotion Luba Mini AWD or Segway Navimow X3 will finish faster and mow in rows, and Worx's own Vision Cloud WR320.1 ($1,799.99) adds RTK for less money. Best for large, simple lawns with obvious edges where zero installation matters more than mowing speed.

Greenworks Optimow 33H
~$1,099
Boundary Wire

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.

Robomow RK2000
~$1,499
Boundary Wire
2.9(9)

Robomow was one of the original robot mower brands (Israeli, now part of MTD under Stanley Black & Decker) and the RK2000 is its mainstream US model: a boundary-wire mower rated for 2,000 square meters, about half an acre, sold mostly through Home Depot at $1,499 with a 3-year warranty. The RK series has a few things older wire mowers lack. The deck floats on a pendulum suspension, the blade disc sits offset so it can trim right over the wire on one side, the four razor blades are staggered on the spinning disc, and it climbs 45 percent inside the mowing area (20 percent along the wire). Runtime is 80-90 minutes with a 60-120 minute recharge, it is quiet at 64 dB maximum, and you can carve the lawn into a main zone plus four sub-zones. Programming happens on a 4.3-inch color touchscreen or over Bluetooth in the Robomow app; remote GSM access is an add-on module. It is also a random-pattern mower with no cameras, so anything you leave inside the wire gets bumped, and the wire itself is a weekend install. Home Depot buyers rate it a middling 2.9 out of 5 across 9 reviews, and Robomow's US presence has thinned since the MTD sale, so weigh that against a Husqvarna Automower 310 Mark II at a similar price with a far bigger dealer network. Pick the RK2000 if you specifically want the offset edge-cutting disc and the touchscreen; pick the Husqvarna for support.

Best for: Half-acre wired lawns where close edge trimming and a touchscreen matter more than app polish or dealer support.

Gardena SILENO flex
~$599
Boundary Wire

The SILENO flex is Gardena's 2025 redesign for the US and, at $599, the cheapest wired mower here from a major brand. It fixes the biggest complaint about the older SILENO City and Life: cut height now runs 1 to 4 in instead of topping out at 2 in, so it finally suits cool-season American lawns. Coverage is up to 8,600 sq ft, slopes up to 35%, and a 10 in cut on an 18V 3.6Ah pack gives about 90 minutes of mowing per 60-minute charge. Navigation is boundary wire plus a guide wire, which is still the most precise way to keep a robot out of the flower beds and lets it thread narrow corridors. It mows in the rain (there is no rain sensor by design, only a frost sensor), is quiet at 60 dB, and is hose-washable. The trade-offs are Gardena's usual ones: the app is Bluetooth-only with roughly a 33 ft range, so no remote start, notifications or GPS, and obstacle handling is a bumper. Anti-theft is a PIN plus a lift alarm. Versus the Worx Landroid M (around $900 street) you get a taller cut and a lower price but lose Wi-Fi control; versus a wire-free Segway Navimow i105 at $999 you give up couch control for a system that never loses satellite lock. Best for small, complex lawns under 0.2 acre where a wire is acceptable and quiet matters.

up to 8,600 sq ft35% slopewire install
Best for: Small, wire-friendly lawns up to about 0.2 acre where a quiet, cheap mower with a tall cut range matters more than remote app control.
