FAQ’s About Robotic Lawn Mowers

How long does a robotic lawn mower last?

Well much like any kind of lawn or outdoor yard equipment, they must be cared for correctly to get the longest operating time.  In the case of a robot lawn mower, that would mean regular cleanings of the underside of the deck, changing the mower blades, and battery care.

In all likely hood, the battery will need to be replaced long before the mower itself wears out.  Batteries tend to last between 5 -10 years, which should give you an idea of the service life of a robotic lawnmower.

Can robot lawn mowers be used in the rain?

Well that depends on the model you have, but most are weatherproof not waterproof, meaning if a rain shower comes up they should be fine.  However, if the forecast calls for rain, then mower shouldn’t be run, but that is for two reasons, it is bad for the mower, and you won’t get great cut

Grass will clump and clog inside of the mower deck, and you will end up clumps of grass in your yard, and a messy robot to cleanup.

Are robot lawn mowers stolen?

Robot lawn mowers can be stolen, like pretty much anything else at your home.

There are some safeguards though for most modern robotic lawnmowers.  These anti-theft features such as PIN codes, GPS monitoring and tracking, and tip over alarms will all help with deterring a would-be robot lawn mower thief.

GPS tracking will allow you to track the mower if it was stolen, but the mower will not work for the thief, because they don’t have a PIN to activate the mower.  Also, these mowers come with audible alarms for when they tip over, so if a thief were to pick up the mower the “tip over” alarm should trigger.

Where does the cut grass go on a robot lawn mower?

Robot lawn mowers are all mulching lawn mowers.  The lawn mowers using mulching blades that cut and recut the grass into tiny pieces that act as a natural fertilizer for the lawn.  This is one of the reasons the robotic lawn mowers run continually, to keep the size of the clippings small.

How often should I run my robot lawn mower?

These mowers were designed to pretty much run every day.  Now in the prime growing season, they should be running every day.  Since the mowers mulch the grass clippings, constant running will produce the best-looking yard.

When grass growth slows, then the runtimes should be shortened and the mower might need to run only a couple of times a week.
