Do not use high pressure washers, detergents, or water in general. In case temperatures drop really low in your area, we suggest you bring it inside. Disconnect the ends of the boundary wire and wrap them with insulating tape to avoid oxidation.
So far so good, now put to bed over winter. Took around 2-3 hours to lay cables around the perimeter of the lawn and set up. Looking at the installation videos really help.
Overall very satisfied. Big test will be next year whilst we are on holiday, looking forward to a cut lawn rather than a jungle.
