What each one does on its own.
The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.
Where they actually differ.
The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

Not compared, because fewer than two of these robots carry a published figure: Price, Suction, Noise.
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
EdgeCut trims to the very boundary using a second deck, but obstacle avoidance is practically non-existent, with no onboard camera to back up the satellite map.
Wire-free installation removes the buried perimeter entirely, on one condition: Wi-Fi has to reach every part of the lawn, or the physical-wire fallback is the only option.
TechRadar calls the cutting efficient yet the behavior temperamental, and complex layouts need the map manually corrected to stop it straying or getting stuck.
Camera-plus-RTK positioning removes the wire and the RTK antenna’s clear-sky requirement, but deep shade and low-sun performance have no published record for this camera-led system.
Haus & Garten Test’s direct review calls the striped cut pattern optimal and complete, yet also recommends it specifically for smaller gardens, a narrower endorsement than its 16,146 sq ft rating implies.
Ten years of included connectivity removes a subscription obligation most 4G-connected mowers carry, though the machine is only five months into a field record too short to establish a reliability pattern.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
- Homes without Wi-Fi coverage across the whole lawn
- Husqvarna states wire-free virtual boundary installation requires Wi-Fi coverage across the full lawn; without it, only the physical-wire fallback is available, adding back the trench-digging step.
- Yards over 9,690 sq ft
- 9,690 sq ft systematic and 6,458 sq ft irregular are the documented coverage ceilings; anything larger falls outside what this Automower is rated for in either mowing pattern.
- Complex layouts needing frequent obstacle handling
- TechRadar reports obstacle avoidance is practically non-existent with no onboard cameras, and complex layouts need the map manually tweaked to stop it straying or getting stuck.
- Gardens with poor satellite sky visibility
- TechRadar states the machine is far too reliant on perfect satellite reception, and coverage degrades specifically where the sky view is obstructed by trees or structures overhead.
- Lawns over roughly 16,000 square feet
- The independent test recommends it specifically for smaller gardens, and the rated ceiling of 16,146 sq ft sits well under larger properties' actual needs in a single charge cycle.
- Deeply shaded yards or heavy tree cover
- Camera-led navigation has no published behavior for deep shade or low sun, and no independent record exists yet for how it performs when a camera is starved for light.
- Buyers wanting a proven multi-year reliability record
- Launched in March 2026, the field record runs under five months, and no independent failure pattern of any kind has had time to accumulate for this specific model.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
- Weekly: Clean the chassis, wheels and blade disc guard with a brush or garden hose (never a pressure washer) and examine the mower for damage and wear; grass-packed wheels degrade slope performance.
- Weekly: Check the blade discs and blades; the manual asks for weekly blade inspection while the mower is new, stretching the interval only once wear proves slow.
- Monthly: Replace the three main-disc blades and their screws as a set; Husqvarna documents a usual life of 3-6 weeks. EdgeCut disc blades run 9-12 weeks, so swap those every second or third blade service. Blade packs start at $26.99 on Husqvarna’s shop.
- Annually: Book the dealer service; the manual assigns the wheel, collision-column, airflow-filter and sealing checks to servicing dealers, and the charging plates and station contacts get polished.
- Seasonally: For winter, fully charge, switch OFF, clean, and store the mower dry and frost free; the charging station top can come indoors while the baseplate stays planted.
- As needed: Replace the battery when runtime between charges shortens; the manual names that as the battery’s end-of-life signal.
- Weekly: Clean the blades and check their efficiency, replacing any that are bent or worn (12-blade kit, art. 1127-0009-01); STIGA’s table sets this at weekly or every 50 operating hours.
- Weekly: Clean oxidation off the recharging contacts and wipe the camera module lens with a soft cloth only; brushes, scrapers and solvents scratch the glass.
- Monthly: Clean the whole mower with a sponge, lukewarm water and neutral soap (never a pressure jet), and have the charging base and power cables checked for wear; documented as monthly or every 100 operating hours.
- Annually: Carry out the servicing at an authorized service centre; STIGA states malfunctions traced to a skipped annual service are not covered under warranty.
- Seasonally: For winter, run the app’s hibernation wizard to register the pre-storage charge (required for the battery warranty), remove the safety key, and store the mower horizontal, dry and protected from ice; recharge at least every 6 months in storage.
- As needed: Battery replacement goes through STIGA technical assistance staff, not the owner; contact a service centre when working range shrinks.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
