How to Winter‑Proof Your Robotic Lawn Mower

A weather‑triggered checklist protects lithium‑ion batteries and electronics from frost to avoid costly spring repairs.

Overview

As night frost appears, owners should update firmware, write down their PIN, fully charge the mower, switch it off, clean the housing and cutting unit, and move the robot to a dry, frost‑free place for storage.
Experts recommend storing the mower and its power supply at around 10 °C to slow battery aging even though some manufacturers list lower minimums such as just above 0 °C.
Leave boundary or loop cable buried over winter but disconnect and dry the cable ends if you remove the charging station, and always follow the maker’s instructions for whether the station must remain powered.
Check and replace blades about every two to three months, inspect the underside every one to two weeks, and expect replacement blade multi‑packs to cost roughly €15–20.
Use a dealer winter service if you lack a frost‑free spot or the mower showed faults, with typical inspection and storage packages running about €100–€200 and higher for pickup and full servicing.
