ComparisonKress KR172 Mission RTKn and Worx Landroid Vision Cloud WR340

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 KR172 Mission RTKn Worx Landroid Vision …
Yard size
Under ¼ acre GoodDesigned for ½-acre minimum; undersized lots see inefficient overlapping paths and poor RTK signal stability. GoodWirecutter ran it on a quarter-acre yard and found it very dependable.
¼ – ½ acrethey differ GoodOptimal range for RTK-based systematic mowing. One-pass coverage achievable with RTK antenna lock. DependsWorx rates 1 acre, but Wirecutter thinks the 5 Ah battery suits quarter-acre yards better.
Over ½ acrethey differ GoodRTK accuracy scales well to multi-acre properties. Extended runtime (up to 180 min) handles 2-acre cuts in one session. DependsWorx lists 1 acre, and no test of the WR340 on a yard over half an acre was found.
Terrain
Mostly flat GoodRTK and LiDAR obstacle avoidance excel on flat terrain; documented performance in residential flat yards. GoodWirecutter found it cut its test yard consistently without hangups or technical snafus.
Gentle slopesthey differ DependsRated for up to 25% gradient; owner reports show traction loss above 20% on wet grass. Steep transitions between flat and slope reduce efficiency. GoodWirecutter saw it manage moderate inclines, and front-wheel drive helped on rough patches.
Steep / hilly PoorHardware limit at 25%+ gradient; documented traction failure on steep hillsides or unstable soil. PoorWorx rates it for 30% slopes, and Wirecutter advises care on steep hills.
Grass type
Typical lawn grass GoodStandard turf cuts cleanly with documented blade cadence. Replacement intervals 6-12 months depending on density. GoodWirecutter found the yard stayed well groomed across its cutting patterns.
Mixed / tall growth DependsSingle-pass efficiency drops on thick or tall fescue; multiple passes may be needed. Blade wear accelerates. DependsNo test of the WR340 in long or overgrown grass was found.
Thick (Bermuda / Zoysia) DependsBermuda and dense turf require frequent blade inspection. Blade dulling visible after 8-10 weeks; check cut quality weekly. DependsNo test in thick or dense turf was found for its 8.7 inch cut.
Boundary setup
Wireless required GoodRTKn is wire-free by design; app-defined virtual boundaries work without perimeter installation. GoodRTK Cloud virtual boundaries need no wire or antenna, per Worx and Wirecutter.
Wire required PoorRTKn does not accept traditional perimeter wire. Satellite RTK positioning is the only boundary method available. PoorWorx lists RTK Cloud navigation with no boundary wire installation option.
No preference GoodWire-free RTK-based operation. No perimeter wire setup required or supported. GoodIts wire-free setup meets a buyer with no boundary preference.

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.
