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 | Stihl iMow 7 |
|---|---|
| Yard size | |
| Under ¼ acre | GoodOversized for small yards; covers efficiently but underutilizes runtime capacity. |
| ¼ – ½ acre | GoodIdeal deployment zone; systematic pattern and 420-min runtime cover this range in single session. |
| Over ½ acre | DependsRated 5,000 sq m (~1.24 acres), the top of the iMOW range; larger yards need a second machine rather than a larger one. |
| Terrain | |
| Mostly flat | GoodFlat terrain is the baseline; iMow 7 excels without slope challenges limiting traction. |
| Gentle slopes | GoodRated to 45% gradient; moderate slopes are well within operating specifications per owner reports. |
| Steep / hilly | DependsNear the 45% limit on wet grass, traction degrades; dry conditions perform better than wet. |
| Grass type | |
| Typical lawn grass | GoodStandard turf and lawn grasses are the design baseline; systematic mowing pattern optimized for normal growth. |
| Mixed / tall growth | DependsTall or overgrown grass may require multiple passes; blade wear accelerates with dense growth. |
| Thick (Bermuda / Zoysia) | DependsThick Bermuda or St. Augustine grass reduces cut speed; may require reduced cutting-height settings or longer run-time allocation. |
| Boundary setup | |
| Wireless required | PooriMow 7 requires physical perimeter wire; no wireless virtual-boundary option available. |
| Wire required | GoodPhysical perimeter wire is the required boundary system; installation is a one-time setup cost. |
| No preference | GoodUses perimeter wire. Fits readers with no boundary preference; wire is required. |
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.
Stihl iMow 7
Wire installation is a permanent setup: any lawn reconfiguration requires physical wire relocation, unlike virtual-boundary or GPS-based alternatives.
Systematic mowing pattern reduces pass overlap compared to random-path alternatives, but the iMow 7 slows for what its ultrasonic sensors register and bumps the rest; it does not plan a route around a newly placed obstacle.
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.
Stihl iMow 7
- Owners who frequently reconfigure lawn areas or garden beds
- Any structural landscaping change requires physical wire relocation. Changing zones means reconfiguring the boundary wire system.
- Buyers seeking GPS, RTK, or virtual-boundary wire-free operation
- The iMow 7 uses a physical perimeter wire only. Wire-free robotic mower alternatives are necessary for owners wanting GPS or virtual boundaries.
- Lawns with complex island beds, narrow corridors, or multi-zone layouts
- Each zone or corridor requires a dedicated guide wire segment. Complex layouts increase installation complexity and risk unmowed strips.
- Households where children or animals routinely occupy the mowing zone
- Ultrasonic sensors slow the mower for larger objects, but nothing on it identifies a person or a pet, and low objects are detected by contact. Scheduling sessions when the lawn is clear remains the reliable mitigation.
- Lots significantly above 5,000 square meters
- Rated coverage is 5,000 square meters and the iMOW 7 is the top of the range, so there is no larger model to move up to. Properties beyond it need more than one machine in adjacent zones.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Stihl iMow 7
- After every use: Clear grass clippings and debris from blade disc and chassis to prevent buildup.
- Monthly: Inspect perimeter wire at surface crossings and obstacles for wear or animal damage.
- Every 3–6 months: Replace blade disc when cut quality declines; replacement blades cost $10–$25 per set.
- Annually: Full perimeter wire inspection including connectors and guide wire segments; clean charging station contacts.
- Annually: Test rain sensor auto-return function before season; clean sensor lens if blocked by residue.
- As needed: Splice or reposition wire sections after landscaping or tool-induced damage.
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.
