Bosch Indego M+ 700 · Greenworks AiMowbot C20Z

Perimeter wire has to be laid once and spliced when it is cut, but it carries no reference station, no satellite sight line and no recurring cost. The install effort is front-loaded rather than ongoing.

Systematic LogiCut coverage is preceded by three full learning cuts, so the first week of ownership does not show the lane pattern the machine eventually settles into.

RTK accuracy removes perimeter-wire labor but concentrates installation friction: base-station mounting and sky-view siting are critical setup steps, not optional.

4WD and vision replace gas-engine maintenance, but blade replacements and RTK station cleaning remain seasonal obligations, just at lighter intensity than the Optimow’s wire-and-blade churn.

Lawns requiring coverage beyond 700 m²

The Indego M+ 700 is rated to 700 m²; larger lawns require a higher-capacity model or additional unit. Coverage of areas beyond the rated boundary will be incomplete.

Renters or temporary property occupants

Perimeter wire installation requires laying and optionally burying wire around the lawn boundary. Relocation cost and effort are prohibitive for tenancy periods under 2–3 years.

Budget-constrained buyers prioritizing entry cost

Unit price is above entry-level wire-guided alternatives. Husqvarna and Worx models at lower price points offer comparable wire-guided Level III operation for smaller lawns.

Owners requiring local-only operation without internet dependency

App scheduling and firmware delivery require a smartphone connection; no documented local-only fallback mode for schedule management without the companion app.

Terrain above the rated gradient, or ground that will not hold traction.

Greenworks rates the C20Z to 24 degrees (45 percent grade) on four-wheel drive. Ground steeper than that sits outside the rating. Thick undergrowth or standing water causes traction and navigation faults independent of slope.

Owners requiring buried perimeter-wire setup.

RTK paired with vision is the only boundary method; there is no wire alternative and no way to skip the app-based setup. Remote scheduling and monitoring need an internet or 4G connection, though mowing itself does not stop when that connection does.

Properties larger than 0.5 acres or requiring multi-zone scheduling.

Single-charge cycle covers roughly 0.4-0.5 acres depending on grass height. Larger lawns need docile pause-and-recharge cycle breaks. No multi-zone or perimeter-subdivision feature documented.
