Put your feet up and let this Gardena lawn mower do the hard work for you. This robotic model can cut at different heights between 20 and 50mm, so it’ll happily munch on your overgrown grass until it’s groomed to perfection. The finely cut clippings are then left on the lawn, which not only keeps it healthy, but means you won’t have a heavy collection bin to empty either. And because it’s really clever, you can even schedule specific days and times when you want it to mow – like when the weather forecast predicts lots of sun. The manufacturer warranty also covers you for 2 years if you need it.
