The quick answer
For a lawn under about 600 m² we recommend the TerraMow Mini 500 at €749 in the EU. In the US, the Sunseeker V3 ReadyGo ($799.99) suits up to 0.15 acre, the S4 ($1,279.99) suits shaded or tightly divided lawns up to 0.25 acre, and the X3 Plus ($999.99) covers up to 0.3 acre. The TerraMow V600 adds app-set cutting height and 4G, listed at €849 in the EU and $1,199 in the US.
How to size a small-lawn mower
Measure the grass, not the plot, and compare it with the manufacturer’s rated area. Then check slope, the width of the narrowest passage, how much shade the lawn has and whether you want to set the cutting height from the app.
Best value in the EU: TerraMow Mini 500
The Mini 500 is rated for 500 m², uses three cameras with no wire or RTK antenna, lists a 150-minute runtime and costs €749. Cutting height is set by hand.
Best EU upgrade: TerraMow V600
The V600 is rated for 600 m², adds electric 25 to 75 mm cutting height, a 203 mm cut and 4G for €849.
US camera-mapping option: TerraMow V600
The US V600 listing is rated for 600 m² (0.15 acre) and adds app-set 25 to 75 mm cutting height, a 203 mm cut and built-in 4G. The official US feed listed it at $1,199 on October 22, 2026, making it a feature-led alternative to the lower-priced Sunseeker options.
Best for the smallest US lawns: Sunseeker V3 ReadyGo
The V3 ReadyGo is rated for up to 0.15 acre, uses Vision AI with no wire and lists a 42% (22°) slope rating for $799.99.

The S4 combines 3D LiDAR with Vision AI, needs no RTK station and lists passages down to 80 cm. It is rated for up to 0.25 acre and costs $1,279.99. Sunseeker says it is not compatible with Zoysia or St. Augustine grass.
