ComparisonKress KR282 EyePilot 4×4 RTKn and TerraMow X AWD

Up to three

All robot lawn mowers. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.

Where each one suits you.

The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.

Fit verdicts by condition for each robot
Condition Kress KR282 EyePilot … TerraMow X AWD
Yard size
Under ¼ acre GoodCapable but overkill for sub-quarter-acre yards. Simpler models adequate; RTK premium not justified. GoodCoverage options start at 0.5 acres, so a lot this size sits inside every configuration TerraMow sells.
¼ – ½ acre GoodKR282 designed for this range. One-charge coverage documented at half-acre; efficiency confirmed in field reports. GoodFalls within TerraMow's smallest 0.5-acre coverage option, on a battery rated for up to three hours.
Over ½ acrethey differ DependsSingle-charge coverage capped near half-acre. Large yards exceed one-session range; consider mulching or docking at midpoint. GoodRated for 1.5 acres standard and 2.7 acres with the expansion battery, which targets November 2026 shipping.
Terrain
Mostly flat GoodRTK excels on flat terrain. 84% slope rating never needed, but mower performs flawlessly here. GoodFlat ground asks little of the suspended four-wheel drive, and Shuttle Drive still avoids pivots at row ends.
Gentle slopes GoodSlopes to ~60% handled confidently. 4WD traction and RTK positioning work in concert; no traction loss reported. GoodIndependent four-wheel drive with dynamic torque distribution and dual suspension is built for roots, ruts and grade.
Steep / hillythey differ Good84% rated gradient addresses slopes where wire-free mowers fail. Wet grass and ice reduce grip; dry/moderate slopes reliable. DependsTerraMow rates it to 90 percent (42 degrees); one preview says that figure still needs real-world verification.
Grass type
Typical lawn grass GoodKentucky bluegrass, perennial rye, and typical lawn turf handled routinely. Baseline performance documented. GoodThree cutting discs span a 50.2 cm deck, with cutting height adjustable from 25 to 100 mm.
Mixed / tall growththey differ DependsInitial dense-growth passes may trigger vision hesitation. Plan light mulching pass before full autonomous operation. GoodCutting height reaches 100 mm (3.9 in), enough to hold a long-cut lawn at its preferred length.
Thick (Bermuda / Zoysia) DependsBermuda or St. Augustine may exceed blade torque on steep terrain. Set higher cutting height initially; reduce over multiple passes. DependsTerraMow markets the 900 W triple-motor deck for thick grass; no independent cutting test has been published.
Boundary setup
Wireless required GoodRTK-based wireless boundary is KR282 standard. No perimeter wire required; app-based setup in minutes. GoodSix-camera vision with nRTK positioning and one-click auto mapping; no perimeter wire is part of setup.
Wire required PoorKR282 is wire-free only. No perimeter-wire option available. Owners requiring wired boundary cannot use this mower. PoorTerraMow's launch material describes only vision and nRTK navigation; no perimeter-wire mode appears in it.
No preference GoodWire-free operation covers this option completely. KR282 works for any preference as long as wireless is acceptable. GoodAny boundary preference works; this mower sets its working area through vision and nRTK auto mapping.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
