What are the running costs of a robotic lawnmower?

Similarly to any other lawnmower ROB will need maintenance from time to time. This maintenance can be carried by an Authorised McCulloch dealer or by you at home. Below are some of the running costs associated with ROB.


The battery used in ROB is maintenance free but it does have a limited life span of 2 to 4 years. Battery life is dependent on the length of the season and how many hours a day ROB is used. A long grass cutting season or many hours of use in a day means that the battery will need to replaced more regularly. You can replace the battery in ROB yourself or take him to an Authorised McCulloch dealer to do it for you.


One cost that you cannot avoid when you own a robotic lawnmower is the cost of the electricity used to run the lawnmower. ROB is cordless and he uses batteries to operate – the batteries need charging regularly. This is an ongoing running cost that varies depending on your power provider and how often it is set to run. The more often you cut your grass, the more frequently ROB will need to charge – therefore the higher the cost of your robotic lawnmower.


A dull or blunt mower blade is more likely to tear the grass, resulting in a poor finish to your lawn. Replacement mower blades are available at the official McCulloch webshop.


In the box of every McCulloch robotic lawnmower, 200 metres of boundary wire is provided. For most users, this is sufficient to install their cordless mower. For more complex lawns, additional boundary wire may be required.
