Kress Robot Mowers

The KR174 tops Kress's residential RTKn range at $2,699.99 (list $3,499.99): rated for 1.2 acre on a 48-hour cycle and 1.7 acre at 72 hours, with a wider 8.7 inch six-blade dual-layer deck, a 6 Ah 20 V pack, 61 dB and 28.5 pounds. It keeps the 1.6 to 3.5 inch electric height range and 40 percent slope rating of the smaller models, plus OAS obstacle avoidance, 4G, GPS tracking and a PIN lock. Positioning is Kress network RTK, so there is no antenna to mount and the mower falls back on dead reckoning under trees, then mows in straight parallel stripes. Kress lists neither runtime nor charge time nor a warranty term on the US page, and the mower sells only through dealers, who must confirm RTKn antenna coverage for your address; the main US web dealer was showing it out of stock in September 2026. The obvious rival is the Segway Navimow X350 at $2,799, which covers 1.5 acre with RTK plus cameras and a base station you install yourself, or the Husqvarna 420 iQ at $3,299 with its own dealer network. The Kress case rests on the dealer install, no mast and stripes, not on specs.

Best for Acre-plus lawns with a few obstacles whose owners want a dealer-installed, antenna-free RTK mower that stripes.

The KR173 is the middle Mission RTKn and the cheapest Kress with OAS obstacle avoidance, at $1,999.99 (list $2,999.99) through dealers. Kress rates it for 0.7 acre on a 48-hour cycle and 1.2 acre at 72 hours, on the same 7.9 inch deck, 4 Ah 20 V pack, 40 percent slope limit and 59 dB as the KR172; it weighs 27.6 pounds. Like its siblings it uses network RTK over built-in 4G, so there is no antenna on your property, mows in parallel stripes and dead-reckons through tree cover. The OAS module on the nose lets it steer around toys and furniture instead of bumping them, which is the main reason to spend $300 over a KR172. Kress publishes no runtime, charge time or warranty term for the US market, and coverage of a dealer RTKn antenna has to be confirmed before you buy. The main US web dealer was showing it out of stock with a free mapping trolley promotion in September 2026, so ask about lead time. Against a Segway Navimow H3000N at $1,299, which covers a similar 0.74 acre with RTK and a base station you mount yourself, the Kress premium buys stripes, a dealer install and no mast. A fit for a half to three-quarter acre lawn with scattered obstacles and a Kress dealer nearby.

Best for Half to three-quarter acre suburban lawns with toys, furniture or beds in the way, within reach of a Kress dealer's RTKn antenna.

Kress is the Positec sister brand to Worx, but its RTKn mowers are a dealer product, and the KR172 is the half-acre entry point at $1,699.99 (list $2,499.99). The pitch is simple: satellite RTK without the antenna. Instead of a base station in your yard, Kress runs its own network of reference antennas hosted at dealers and pipes corrections to the mower over 4G, so setup means drawing a boundary in the app rather than hunting for a spot with clear sky. When trees or the house block satellites it falls back on inertial navigation and odometry, and it mows in straight parallel stripes rather than the random bounce of a Robomow or older Husqvarna. Specs are modest: an 8-inch cut, 1.6 to 3.5 inch height range, 40 percent slopes, 59 dB and about 26 pounds, with a 4 Ah 20 V battery and 0.5 acre recommended (0.7 acre maximum). What you do not get is camera obstacle avoidance; that is reserved for the OAS variant and pricier Kress models, so this one relies on its bumper and your no-go zones. The catch is coverage: RTKn only works if a Kress dealer antenna is within range of your address, so the dealer has to confirm that before you buy, and you are tied to that dealer for service. Against a Segway Navimow i110 you pay more for the no-antenna convenience and stripes. Good for a suburban half acre near an established Kress dealer; skip it if nobody nearby carries the brand.

Best for Suburban half-acre lawns within range of a Kress dealer's RTKn antenna, for buyers who want stripes and dealer support without an RTK mast in the yard.

The KR161 is the bottom rung of Kress's Mission RTKn ladder: a quarter-acre mower at $1,499.99 (list $2,099.99) sold and installed through Kress dealers rather than online. It shares its body with the KR172 and KR173, so you get the same 7.9 inch three-blade disc, 1.6 to 3.5 inch electric height range, 40 percent slope rating, 59 dB and 26.5 pounds, but with a 4 Ah 20 V pack and a 0.25 acre rating. Positioning is Kress's network RTK, which pulls corrections from a dealer-hosted antenna over the built-in 4G, so nothing is mounted at your house and the boundary is drawn in the app. It mows in parallel stripes and dead-reckons through shade. What it lacks is any obstacle avoidance beyond the bumper and lift sensor; the OAS camera module starts at the KR173. Two caveats: RTKn only works where a dealer antenna covers your address, and a published one-star owner review describes a drive failure after six weeks and weak signal under cloud and heavy foliage, with support routed through the dealer. Against a Segway Navimow i110N at $929, which adds a camera for the same quarter acre, you are paying for dealer setup and stripes. Fits a small, open suburban lot near a Kress dealer.

Best for Small, open quarter-acre lots within range of a Kress dealer's RTKn antenna, for buyers who want stripes and a dealer install at the lowest Kress price.
