What Size of Lawn Is a Robotic Mower Good For?
Lawn size is the first number to check before buying a robotic mower. The surface area matters, but so does the shape of your garden. Here is how to measure it and what to look for.
In short: measure your lawn in square meters, compare it with the coverage listed for the model you are considering, then leave a margin for slopes, narrow passages and obstacles.
Start with the size of your lawn
| Lawn size | Typical garden | What to look for |
|---|---|---|
| Under 300 m² | Town house, small family garden | Compact design, quiet motor, easy docking |
| 300 to 800 m² | Suburban house | Runtime per charge, recharge time, app scheduling |
| Over 800 m² | Large plot, country garden | Rated coverage, automatic recharge and resume, several sessions per day |
These ranges are general guidance. Always compare your measurements with the coverage stated for your specific model.
What reduces the area a mower can really cover
- Slopes take more time and battery than flat ground.
- Narrow passages are crossed slowly and count for less usable area.
- Obstacles such as flower beds, trees and toys force the mower to reroute.
- Long or wet grass slows the mower down.
How to measure your lawn
- For a rectangle, multiply length by width in meters.
- For an irregular shape, split it into rectangles and triangles, then add them up.
- Subtract flower beds, terraces and ponds.
The SMAST MKSVII runs up to 150 minutes per charge and recharges in about 2 hours. It docks itself when low and resumes where it stopped, so a larger lawn can be mowed across several sessions.
