Husqvarna Automower Aspire R4
A favourite wired mower

Review Summary
A compact mower in terms of size and storage, for compact lawns. The Husqvarna Aspire R4 has a couple of features to help it stand out from the crowd of basic wired robo-mowers. These include the passage handling ability, whereby it detects narrow areas, and switches from random bounce to a systematic mowing mode to avoid too many turns in a tight space, which can lead to wheel tracks/lawn wear. Additionally it features IFTTT allowing you to control the mower along with the rest of your smart home, and have more complex triggers. For instance, you can set the mower to automatically stop when you come home. Everything else is fairly standard for a wired mower, but it is easy-clean, which is a feature I really appreciate.
One word of caution this mower is not great at slopes, so if you have a hilly garden you may want to avoid.
