Robotic Lawn Mowers

The idea of owning a robotic lawn mower should appeal to DIY enthusiast all over the world. How many times do we feel we have to leave off doing one job to make sure the lawn is cut before the weather changes for the worse? In recent years the technology behind robotic lawn mowers has improved tremendously, this means more and more people are buying them and, like any commodity, the more that are sold - the more the price of them drops.


It’s not just DIY enthusiasts that are buying robotic lawn mowers. Owning a robotic lawn mower could also help reduce your stress levels! I can just imagine having asked one of the kids to mow the lawns for the third time; to be met with the inevitable glazed look or grunt - and again you find yourself doing it rather than finishing that other job or just relaxing after a hard days work.

Or, it might be that you’re infirm or just too elderly to mow the lawn any more, a robotic lawn mower is just the thing to help you out. If you’re fortunate enough to be able to pay someone else to mow the lawn for you then you might not need a robotic lawn mower. However, with robotic lawn mower prices typically now between $1000 and $2000 - it could easily pay for itself within 2 years!

How Does it Work?

Needless to say robotic lawn mowers combine the conventional workings of an electric mower with the latest in micro-processor and sensor technology. Using a length of wire, usually supplied with the robotic lawn mower, you set out the parameters in which you want the robot to work in. This could be just setting the wire along the edges of a lawn and a flower border, or it could include setting the wire around a garden pond, or path …. etc. The robotic lawn mower can then start work mowing the grass, using the wire setting as its limits in which to work.

Any trees or large objects in its path that were not ‘marked’ by the wire will either be circumvented or, if hit, the robot will reverse away and then determine an alternative path around the object. The wire forming the limit of the robots operation does carry a small electrical charge, as the robotic lawn mower ‘senses’ it according to the electro-magnetic field it emits. However, the electric charge in the wire is very small and entirely harmless. If you prefer, you can bury the wire under the grass to a depth of about one foot.

Powered Robotic Mowers

Robotic lawn mowers are powered by battery operated electric motors. The battery is a rechargeable one and it is best to re-charge it after each time the robotic lawn mower is used. Obviously allowing the robotic lawn mower to get wet in the rain is not a good idea. Robotic lawn mowers are fitted with rain sensors and, if it were to start raining whilst it was in operation, it can be programmed to return to it’s charging base; which will typically be in a garage or other building.

Being fully programmable you don’t even need to be in your garden for the robot to start mowing the lawn. You can pre-set the date and time that it will start to work using it’s remote control, leaving it to do all the work and you to have none of the worry. There’s even no need to worry about disposing of the grass clippings. Robotic lawn mowers can finely chop up the grass clippings and deposit them back on the lawn, returning the nutrients to it.

Maintenance of robotic lawn mowers is quite simple, making sure the power is off - after each use brush the underneath with a stiff brush and, if wet, leave it to dry before charging it again. Apart from that, occasionally oiling the wheels and changing the blade, as recommended by the manufacturer, are all that’s required.
