WORX Robot Lawn Mowers Compared (WR341, WR342, WR344, WR346)
Most yards want the WR342. Step down to the WR341 only if a quarter acre is a hard ceiling. Step up to the WR344 or WR346 only once the extra acreage is the actual reason you are paying more, and the 4G radio or the headlight bundled with it is not.

WORX Landroid Vision Cloud 4WD WR341
Stop here if a small, flat lawn that will never need more than a quarter acre, where the lower price matters more than headroom.
WORX Landroid Vision Cloud 4WD WR342
Stop here if a half acre yard with real slope in it. The WR342 is also the mower our full review covers.
WORX Landroid Vision Cloud 4WD WR344
Stop here if a full acre, or a yard where the mower is also working after dark or too far from the router for RadioLink to help.
WR346
Stop here if an acre and a half, if a US listing turns up. Until then, buy the WR344 unless the lawn is bigger than one acre.
No US listing to link. Named here because it is part of the maker's own ladder.

Four WORX robot lawn mowers share one chassis and one battery platform: the WR341, WR342, WR344 and WR346.
Split only by how much lawn each is rated to cover, a quarter acre, a half acre, a full acre and an acre and a half. Read WORX's own spec sheet for any one of them and three quarters of it repeats across the other three. The WR342 already leads our robot mower picks at the half acre size. Read on before stepping off that one rung in either direction.
Which WORX robot lawn mowers are actually different
Every rung runs RTK Cloud positioning plus a stereo-vision V-SLAM camera, so none of them needs a boundary wire, a base station or a rooftop antenna. Every rung cuts with the same 8.7 inch three blade deck, adjusts electrically from 1.57 to 3.54 inches, and carries the same Cut-to-Zero edge module and multi-zone scheduling. And every rung, from the smallest to the largest, is rated for the identical 84 percent slope, 40 degrees. Buying the bigger mower does not buy a mower that handles a steeper yard. WORX rates all four the same way on that axis. Slope is not the reason to move up this particular ladder.
What changes, rung by rung
WR341: the quarter acre entry rung
The WR341 is the base of the ladder: a 20V 4Ah battery on a 90W charger, an 80 minute charge time, and Bluetooth plus Wi-Fi only. It carries no RadioLink and no 4G, which on a lawn this size is not a real loss, since a quarter acre rarely puts the mower far enough from the router to need either.
WR342: doubles the coverage, adds RadioLink
The WR342 doubles the rated lawn to a half acre and steps the battery to 5Ah, which is why the charge time rises to 100 minutes on the same 90W charger as the WR341. It also adds RadioLink, which WORX describes as connectivity for reliable coverage in large or complex yards. It is the rung our WR342 review covers in detail, including the setup week two owners both called the hard part.
WR344: doubles it again, trades RadioLink for 4G
The WR344 doubles the rated lawn once more, to a full acre. Its battery stays a nominal 5Ah, the same capacity as the WR342's, but the charger jumps to 190W and 5A. That cuts the charge time to 60 minutes despite the bigger yard waiting on the other side of it, faster than the WR341 manages on a quarter of the lawn. RadioLink is gone from the spec sheet. Free 4G takes its place, and a FiatLux headlight ships standard, an option WORX otherwise sells across the rest of the lineup, which matters more on an acre that takes longer to finish before dusk.
WR346: the acre and a half top, not sold here
The WR346 tops the ladder at an acre and a half, on an 8Ah battery and a 230W charger that holds the charge time to 65 minutes despite the largest pack in the line. It keeps the WR344's 4G and headlight, and no US Amazon listing carried it at the time of writing, so confirm it is actually for sale before planning around it.
Who should stop where
Coverage decides this ladder, not slope.
Measure the lawn before anything else. A quarter acre or less is the WR341, and paying more for the WR342 buys headroom that goes unused. A half acre with real slope in it is the WR342, which is also the only rung in this lineup we have put in front of an accuracy review against owner reports and WORX's own documents. A full acre, or a yard where the mower keeps running after the sun goes down, is where the WR344's 4G and headlight start earning their keep instead of sitting unused.
If slope is not the issue and the yard is flat, WORX's own two wheel drive WR320 covers the same half acre as the WR342, without the 4WD chassis. It is the mower to check before paying for four wheel drive nobody's yard is asking for.
