How we score robot mowers
Every robot mower on easymower gets an overall score out of 10, built from six sub-scores. Some are calculated automatically from specifications and prices. Others are editorial judgements. This page explains each one, so you can decide how much weight to give them.
Important: we haven't tested these mowers hands-on. None of the scores reflect time spent with a mower on a lawn. They are desk-based assessments of what the manufacturer publishes.
The weights
| Part of the score | Weight | Based on |
|---|---|---|
| Navigation | 25% | Calculated from specifications |
| Cut quality | 20% | Editorial judgement |
| Ease of setup | 15% | Editorial judgement |
| App | 10% | Editorial judgement |
| Value | 20% | Calculated from specifications |
| Support | 10% | Half warranty terms, half editorial |
The table is generated from the same code that calculates the scores, so it always shows the weights currently in use.
Navigation (calculated)
Navigation starts from base points for the type of system the mower uses to know where it is:
- Perimeter wire: 5.5 points
- Vision (camera): 6.5 points
- RTK (own base station): 7 points
- Network RTK: 7 points
- LiDAR: 7.5 points
- Hybrid (RTK + vision/LiDAR): 8 points
It then gains points for features listed in the specification:
- 1 point for obstacle detection that doesn't rely on bumping into things (cameras, LiDAR, ultrasonic or similar);
- 0.5 for no-go zones;
- 0.5 for managing two or more zones;
- 0.5 if the manufacturer states it can pass through gaps of 80 cm or less.
The total is capped at 10. A feature the manufacturer doesn't document earns nothing.
Cut quality, ease of setup and app (editorial)
These three are judgements made by our editors from manuals, spec sheets and published documentation, on a 0–10 scale in half points. Most models land between 5.5 and 8.5.
- Cut quality looks at the blade system, the cutting width relative to the rated area, the height range and how it's adjusted, edge-cutting claims and whether the mower mows in lines or at random.
- Ease of setup rewards mowers that need no buried wire and no base station, and marks down buried wire, dealer-only installation and unclear instructions.
- App looks at documented features such as zones, no-go areas, schedules, per-zone cutting heights, software updates, map editing and 4G, and whether the app is needed for basic use.
These are informed opinions, not measurements. We apply the same rubric across every brand and revisit scores when documentation changes.
Value (calculated)
Value compares price per rated square metre with every other current model. For each mower we take the version with the lowest price per m², using the lowest current UK price or, if there isn't one, the RRP. That figure is ranked as a percentile among current models: the cheapest per m² scores 10 and the most expensive scores 3. Small bonuses apply for built-in 4G with no subscription required (0.5) and an included garage (0.3). Because it's relative, a model's value score can change when prices or other models change.
Support (half calculated, half editorial)
Half comes from the warranty length (the extended warranty where one is offered), and half from an editorial judgement of warranty conditions, UK presence and parts availability.
The overall score
The overall score is a weighted average of the sub-scores. If some are missing, for example because there's no price for the value calculation, the rest are re-weighted, but only when at least 70% of the total weight is present. Below that, the model has no overall score rather than a misleading one.
Changes to the method
The method has a version number, shown in the table caption above and alongside scores. When we change a weight or a rule, the version changes and every score is recalculated at the same time.
