eufy Robot Mowers

The E18 is the eufy E15 with a bigger battery: same 8 inch three-blade disc, same 1 to 3 inch cut, same twin stereo cameras and roofed base station, same 18 degree (32 percent) slope limit, but rated for 0.3 acre instead of 0.2. PCWorld confirmed the two are otherwise identical, so everything said about the E15 applies, good and bad. The good is the setup: PCWorld went from box to first mow faster than with any mower it had tested, and another tester mapped a yard in about 45 minutes with no wire, antenna or perimeter drive. The cut is even from the first pass and the 3D perception dodged toys, furniture and a dog, then came back for the patch it skipped. The bad is the camera-only navigation: it cannot mow after dark, it read sun glare and tall grass as obstacles, it kept tripping on walkway stones, it returns to the dock after mapping each zone, and rear-drive plastic wheels plus that 18 degree limit make it a flat-lawn machine. Availability is the other wrinkle. eufy's US store now sells only the E15 standalone, Best Buy has stopped selling the E18 new, and the live US listings are Lowe's at $1,399.99 (down from a $1,999.99 launch price) and Amazon. That is roughly $100 more than an E15 for 50 percent more rated area, which only matters if your lawn is genuinely over 0.2 acre; on a smaller lot the E15 is the same mower for less. Best for flat, fenced lawns between 0.2 and 0.3 acre whose owner wants the simplest possible setup and will never need a night cut.

The eufy E15 is the robot mower for people who already own a robot vacuum and want the lawn version: unbox it, plug in the roofed base station, and its twin stereo cameras auto-map a 0.2-acre yard in 10 to 25 minutes with no wire, no RTK antenna and no perimeter drive. TechRadar, How-To Geek and Amazon owners all rave about how painless that first day is, and the 56 dB cut from three razor blades on an 8-inch disc leaves tidy stripes. The camera-only approach has real limits, though. It cannot mow after dark, it is rated for only 18-degree (about 32%) slopes, its rear-drive plastic wheels slip on dewy grass, it wants lawn edges that look different from the lawn, and Tom's Guide watched it misread longer grass and skip patches. Grass within about 4 inches of walls still needs a trimmer. It is an Anker product underneath (the mower is a rebadged TerraMow), so the app is polished, build quality is high, and you get built-in 4G, GPS anti-theft alerts, an AirTag slot and a 2-year warranty. eufy lists it at $1,799.99 but it has sold at $1,299.99 or less for most of 2026, which puts it against the Ecovacs GOAT O1000 RTK and Segway Navimow i110N; the E15 is easier to set up than either, while those two handle shade, slopes and night mowing better. Best for flat, fenced suburban lawns under 8,700 sq ft where setup simplicity matters most.
