Robot Mowers
Built for people
The Husqvarna Automower Aspire R4 is a small, lightweight robotic lawn mower designed for compact gardens rather than large or complex properties. Its 400 m² working area capacity makes it a practical choice for town gardens, small suburban lawns, and simple layouts with narrow passages. A key strength is convenience. The Automower Connect app lets you manage and monitor the mower from a phone, while Bluetooth and Wi-Fi connectivity support everyday control and updates. It also works with smart home systems, including Amazon Alexa and Google Home, which is useful if you want status updates or voice control. Cutting performance is aimed at regular maintenance rather than heavy recovery mowing. The mower uses three pivoting razor blades and cuts between 20 mm and 45 mm, so it is best used frequently to keep grass consistently short. The weather timer can adjust mowing time based on grass growth, and the frost guard helps protect the lawn by pausing mowing in frosty conditions. The Aspire R4 is also well suited to small storage spaces. Its compact body, low weight, and included storage hook make it easier to store than many larger robotic mowers. The IPX5 rating and hose-cleanable design are practical advantages for routine upkeep. The main trade-off is that this is not a wire-free robot mower. It uses a physical boundary wire, and the standard package may not include loop wire or stakes unless you buy a version with an installation kit. It also lacks GPS theft tracking, GeoFence, object detection, and an alarm, so buyers should consider where the mower will be used and stored. Overall, the Automower Aspire R4 is a strong fit for small, relatively simple lawns where app control, compact storage, and reliable scheduled mowing matter more than advanced navigation or premium security features. If your lawn is larger, steep, highly fragmented, or you want wire-free setup, a higher-end model may be a better choice.
