Worx Landroid M WR147

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.

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.

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.

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 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.

The SILENO minimo is Gardena's smallest, quietest mower and, at about $530 on Amazon, the cheapest way to get a European-built robot onto a tiny lawn. It is rated for 2,700 sq ft, climbs 35%, and at 57 dB is about as loud as a refrigerator, so nobody will notice it running at 2 am. Setup is boundary wire and a single guide wire; CorridorCut lets it pass through gaps down to about 24 in, and SensorControl adjusts how often it mows to how fast the grass is growing. It runs about 65 minutes per cycle on its 18V pack and recharges in 75. Now the limits: cut height maxes out at 1.8 in, which is too short for fescue or bluegrass and really aims it at Bermuda, zoysia and other warm-season grass; the app is Bluetooth-only with a 33 ft range, so no remote start or alerts; there is no rain sensor (it simply mows wet), no edge mode, and obstacle handling is a bumper. Gardena has shifted its US lineup to the SILENO flex ($599, 1 to 4 in cut, 8,600 sq ft), and the minimo appears to be selling down remaining Amazon stock, so treat it as a closeout buy rather than a long-term platform. Against a Worx Landroid S it is quieter and cheaper but far less connected. Best for a postage-stamp warm-season lawn where silence and price beat features.
