Where this information comes from

Garden Robot Atlas has not physically tested this mower. Everything below is based on the manufacturer's published specifications, with the source documents linked at the bottom of the page.

Is it right for your garden?

Each judgement below is derived from a published figure. Where the manufacturer has not published one, we say so instead of guessing.

Lawn size
Recommended: 5,000 m²

The manufacturer publishes 5,000 m² as the recommended lawn area. Read the linked source for its test conditions and check that your slopes, layout and available mowing hours are comparable.

Slopes
Very steep slopes

Rated for gradients up to 84% (about 40°). Measure your steepest section before deciding — a bank that exceeds the rating is outside the published operating limit; performance and safety are not warranted.

Trees and overhead cover
Check tree cover

RTK correction source and fallback behaviour vary by model. Check the manual for coverage requirements under mature trees and beside tall buildings.

Separate areas
Up to 120 zones

Separate areas — a front and back lawn, for example — can be mapped as distinct zones. Check whether the mower can drive between them on its own or needs carrying.

Installation
No boundary wire

Boundaries are set in the app rather than with a buried cable, so the layout can be changed at any time without digging.

Rows marked “not published” are values the manufacturer does not state.
