This is the amazing bit – the daily running costs of robot mowers and Husqvarna Automower – are just the cost of electricity needed to recharge their batteries. This cost amounts to approx £40.00 / year. It is advised to get your automower / robotic mower serviced each year (and to also get a software update – which gives you the benefit of all improvements as they become available, your local dealer will advise you of any charged here ). You may also with to change the blades ( the Husqvarna Automower often come with spares sets of blades included ).
Other than that – there are no running costs.
