Maker's correction service Verified [2]
Positioning depends on Kress's RTKⁿ correction network reaching the lawn. Kress does not document a local reference station as an alternative, so this is not satisfied by being able to mount an antenna.

Does this model suit your yard?
The figures above are what the manufacturer publishes. Whether they clear your lawn depends on numbers only you have — so the useful next step is to put yours in, or to read what the ones that matter most for this model actually mean.
- Do you need an antenna or reference station, and where does it go? Its correction arrives over the manufacturer's own service, so coverage at your address decides it.
- Robot mower slope ratings: what the numbers really mean It publishes one slope figure and no separate rating for the boundary.
- Front yard, back yard: mowing separate areas It states that it can hold and mow more than one separate area on its own.
- Wire-free or buried wire: what you're really choosing It installs without a buried wire, which is not the same as having nothing to install.
- Measure your yard before you shop: a practical checklist Whichever models you shortlist, these are the measurements that decide between them.
Based on published manufacturer specifications, not hands-on testing.
