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.
| Condition | Greenworks Optimow 15 |
|---|---|
| Yard size | |
| Under ¼ acre | GoodWell within the 0.37-acre coverage limit; capable, though a smaller-class mower may serve this lot equally well. |
| ¼ – ½ acre | GoodSits within the documented 1,500 m² (0.37-acre) ceiling; the Optimow 15 is rated for this size range. |
| Over ½ acre | PoorCoverage limit is 1,500 m² (0.37 acres); yards over half an acre exceed the documented operating limit. |
| Terrain | |
| Mostly flat | GoodFlat terrain is fully within operating envelope; no gradient concerns apply. |
| Gentle slopes | GoodRated for up to 35% gradient; moderate slopes are comfortably within documented operating limits. |
| Steep / hilly | DependsGreenworks specs the Optimow 15 at 35% maximum; sections near that limit warrant extra caution when grass is wet. |
| Grass type | |
| Typical lawn grass | GoodRandomized mulching-cut pattern designed for standard-height turfgrass on a regular mowing schedule. |
| Mixed / tall growth | DependsOvergrown grass above the blade design height may need a manual pre-cut before returning to regular automated sessions. |
| Thick (Bermuda / Zoysia) | DependsDense thick-blade turf can slow progress; frequent short-duration passes are the documented mitigation for this grass type. |
| Boundary setup | |
| Wireless required | PoorThe Optimow 15 requires physical perimeter wire; no wireless or GPS boundary option is available on this model. |
| Wire required | Good200 m of perimeter wire is included; the entire operating boundary is wire-defined, matching this setup. |
| No preference | GoodThis model is wire-only; factor in the one-time perimeter installation before committing to this setup. |
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.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Greenworks Optimow 15
Wire installation is the price of entry: the Optimow 15 delivers genuine unsupervised mowing, but only after the owner commits several hours to perimeter-wire layout and staking.
Randomized cutting works, but systematic GPS-based mowing completes large areas faster and with more predictable pass distribution; the Optimow 15 trades path efficiency for a lower price tier.
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.
Greenworks Optimow 15
- Yards exceeding 1,500 m² (0.37 acres)
- The 1,500 m² coverage ceiling is a documented hard limit. Larger properties require a higher-capacity model; exceeding the rated area results in incomplete coverage cycles.
- Owners who cannot or will not install perimeter wire
- The Optimow 15 requires perimeter wire for all boundary definition. No GPS or camera-based wire-free operation is supported. Wire installation is mandatory, not optional.
- Properties with dense obstacles or numerous internal garden beds
- Randomized-pattern mowers lack systematic zone mapping. Dense obstacle fields or numerous internal garden beds require extensive guide-wire loops, adding installation complexity and wire-break risk.
- Slopes exceeding 35% or areas with loose surface conditions
- The 35% gradient rating is the published hard limit. Steeper sections or slopes with wet clay at the boundary are outside the documented operating envelope.
- Households requiring Wi-Fi or local-network integration
- Connectivity runs over GSM (cellular module), not home Wi-Fi. Smart-home integrations dependent on local Wi-Fi are not supported on this model.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Greenworks Optimow 15
- After every use: Visually inspect blade disc for damage or grass clogging.
- Weekly: Clear accumulated clippings from the chassis underside and blade housing.
- Monthly: Inspect boundary wire and pegs along the full perimeter; re-stake any lifted sections.
- Every 3-6 months: Replace blade disc or individual blades; standard Greenworks Optimow replacement parts.
- Seasonally: Clean charging contacts on dock and mower body; verify boundary wire continuity before mowing season.
- Annually: Full perimeter wire inspection; replace degraded sections; charge battery to storage level before winter.
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.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
