Sunseeker S4 (RMR1001M20V)
The manual specifies 1,000 m² and a maximum 42% slope. Check bottlenecks too: passages must be wider than 80 cm. The 18 cm cutting width and manual 20–60 mm height suit regular maintenance; rated area does not guarantee the same work rate in a fragmented garden.
Measure the garden before choosing
The manual specifies 1,000 m² and a maximum 42% slope. Check bottlenecks too: passages must be wider than 80 cm. The 18 cm cutting width and manual 20–60 mm height suit regular maintenance; rated area does not guarantee the same work rate in a fragmented garden.
Station, mapping and zones
Allow level ground, power and Wi-Fi at the station, with 1.5 m clear in front. Virtual boundaries remove cable installation, but zones and corridors still need correct connections in the app. A flush path edge differs from a raised lawn edge, so some manual trimming may remain.
Plan for maintenance and winter storage
The manufacturer calls for weekly inspection. Keep wheels, camera and station clean; switch off before maintenance and avoid pressure washing. Replace blades and screws together. For winter, clean and store the charged, switched-off mower somewhere dry and frost-free. The manual explains servicing and error codes.

What owners report
The eight French accounts are mainly favorable first impressions: wire-free setup, mapping and mowing results are praised. Reservations concern preparation time, low branches and one localization problem. Seven reviews carry a Verified Purchase label; the eighth does not.
Encouraging start, limited long-term evidence
Several buyers write after one week or just after delivery. They appreciate avoiding wire and the way the mower moves around objects. One mentions roughly 800 m², but the sample contains no measured slopes: these accounts do not replace the manual’s technical limits.
Mapping, vegetation and support
One review describes time spent on mapping and uncut grass beneath low branches. The same buyer reports responsive support after an app mistake. Another reports only a localization problem and a return, without enough context to identify the cause.
Reported positives
- Wire-free setup appreciated
- Useful mapping and zone options
- Satisfying cut in early use
Reported negatives
- Mapping sometimes takes longer than expected
- Grass left beneath low branches
- One report of failed localization
