- Small to medium yards
- Hands free lawn
- Value robot
The Worx Landroid M WR140 is a value-oriented robot mower that handles hands-free daily mulching on up to a quarter acre, with Wi-Fi app control, an included GPS module, quiet 63 dB operation, and a narrow 7-in deck for tight spots. The trade-offs are a multi-hour boundary-wire install, a 35% slope ceiling, and that it has been replaced by the newer WR147, so weigh stock and parts support before buying.
Pros
- Much cheaper than premium robots while still delivering hands-free daily mulching mowing on up to a quarter acre
- Wi-Fi and app control with an included GPS module allow scheduling, tracking, and automatic software updates
- Quiet 63 dB operation and a narrow 7-in deck navigate narrow passages and cut close to edges
Cons
- Boundary-wire install takes hours and the wire can be cut by aeration or edging and needs winter storage in cold climates
- Quarter-acre coverage and 35% slope limit rule it out for large or steeply terraced lots
- The WR140 has been superseded by the WR147, so new stock is thinning and long-term parts support is a consideration
