Buying Guide
Lawn size and layout
Match the mower's recommended coverage to your garden — small robot mowers are typically aimed at very small to small urban lawns. Check the manufacturer’s stated maximum area and consider complex layouts, narrow passages and lots of flowerbeds which reduce effective coverage.
Terrain, slopes and obstacles
Look at the mower’s slope handling and obstacle navigation: some compact models manage gentle inclines well, but steeper banks or lots of steps will need a more capable machine or manual trimming. Also consider how it detects and avoids obstacles and whether it can handle uneven turf without bogging down.
Battery life, runtime and charging
Battery capacity and runtime determine how often the mower needs to return to its base — shorter runtimes are common in small models but are less of an issue for small lawns. Check charge time and whether the mower will resume automatically after recharging or if it needs manual intervention.
Installation, boundaries and maintenance
Decide whether you want a model that uses boundary wire (more precise) or a more advanced GPS/guide-wire-free system. Factor in initial installation time and ongoing maintenance such as blade changes, winter storage and occasional cleaning — small models are usually simpler and cheaper to maintain.
Connectivity, features and security
Consider app control, scheduling, rain sensors and anti-theft measures such as PIN codes and alarms. While connectivity is handy for remote control and updates, simpler machines may offer better value if you just want a low-maintenance cut.
