If you’re wondering how this little robot knows where to go, there are boundary wires included – you simply set them up and Flymo will detect them, knowing not to cross over them.

Things to Know Before Buying a Robot Lawn Mower

A robot lawn mower, what’s not to like! These nifty little machines will cut the grass in your garden for you, leaving you free to do other things (or to do nothing at all!).

If you want to spend more time enjoying your garden, and less time maintaining it, then a robot lawnmower is perfect for you.

The best robot lawn mowers can be programmed to mow the lawn whenever you like, getting it ready for when you want to use it. They can even mow at night as they are virtually silent.

The following information will help you learn more information about these excellent gadgets, and know what to look out for:

  • They’ll free up a lot of time. This is pretty much a no brainer, but however much time you usually spend mowing the lawn, you’ll be able to dedicate to something else. One step closer to efficient living!
  • They’ll improve the health of lawn through mulching. The regular cutting that robot lawn mowers do is great for the health of your grass; they cut so often that the trimmings are always very small. These tiny trimmings provide a great mulch; you’ll barely even notice it but it will feed valuable nitrogen back to your lawn.
  • They can mow at night. Robot lawn mowers are so quiet that they can mow at night without disturbing you or your neighbours. This perfectly frees up your lawn to be used during the day without any interruptions.
  • They’re extremely efficient. You won’t need to spare another thought for cutting your lawn once the robot mower is set up. They have lots of clever and helpful functions and some models can even automatically develop a cutting schedule for you.

Setting up a robot lawn mower doesn’t take too long. Plus, the time is more than made up for when you never have to mow the lawn again!

They come with their own charging stations and when their power gets low they just make their way back to the station to recharge. They can be left out in all conditions even on rainy days.

You should make sure to follow the manufacturer’s guide for installation, but these are some general guidelines:

  1. Choose a position for the charging station. This needs to be placed somewhere along the edge of the lawn you want to cut. Don’t place it on a path or patio. The charger will need to be in reach of a mains power port.
  2. Mark out the perimeters of the lawn with boundary wire. These wires sit flush with the ground and aren’t a trip hazard if installed correctly – just make sure they’re low enough.
  3. Using the pegs provided, peg down the boundary wire.
  4. Install the guide wire. This goes from the charge station to the boundary wire.
  5. Put your robot on the charging station. Turn it on, and program it according to your desired settings.

There are a variety of ways that different models can be scheduled. Some use apps and some have integral programmers. Some will just run for a certain amount of time each day while some can be fully scheduled for certain times and days each week.

Most robotic lawn mowers are designed to be left outside in all weathers. Some will cut when it is raining, and some will return to their charging station during rain and reschedule cutting for a later time.

You can get robot lawn mowers equipped with security features such as PINs, alarms, or the inability to be used without their paired charging system. These features all discourage theft.

Different robot lawn mowers are suitable for different sized lawns. This will depend on their battery life.

They will state how large a garden they are suitable for in meters squared. Before considering which robot lawnmower to buy, measure out the area of lawn that you would like it to cut. Simply multiply the length by the width to find out the square meterage.

You should buy a robot lawn mower which has a maximum coverage area just larger than the size of your lawn. This will work to give a bit of leeway which is always useful.

Certain robot lawn mowers are better equipped to tackle obstacles and uneven garden terrains.

Most can manage inclines of up to approximately 20%, but the cheapest models may struggle to cut on these slopes effectively. You may end up with wavy, uneven mowing, and it’s advisable to fork out a little bit more if you have a sloping garden.

To calculate the slope % of your lawn, you will need to know how much it rises by, over what distance. You can use a laser level to work this out. There are also slope calculators online that make the calculations easier.

If you have a basic, flat lawn without many obstacles, you’ll find that the majority of robot mowers will do a good job.

If your lawn has some tight angles or narrow spots, you will need to consider this when buying the mower. The width of the mower might be important to know if you are hoping it will cut tight spaces between flowerbeds. Some robots are more adept at navigating these small spaces than others, which is worth looking out for in their specifications. Some mowers specifically advertise themselves as being more agile.

If you are hoping to use a robot mower to accurately cut around obstacles or more complicated garden features, you may wish to consider a robot mower that can be customised with ‘add-ons’.

Even if you don’t want to customise your robot mower right away, it may be useful to have a model that can be added to later.

The Worx M700 Landroid Robotic Lawn Mower is one such model that can be customised. Amongst the add-ons you can buy is one called ‘Off Limits’. This will create boundaries without needing to use a boundary wire. You can also buy different wheels if you need them for tougher terrains.

Speaking of tougher terrains, if you’re hoping that your robot mower will be able to travel over patio or concrete to get to different sections of your lawn, this is possible – but you’ll need to make sure your specific model is built for that. Again, some Worx models are up to the challenge, as well as some Flymo options. Be sure to check first!

Some robot mowers, such as the Bosch DIY Robot Lawn Mower, can be controlled by apps.

This means that wherever you are, you can keep an eye on what your mower is up to, and program it to do something else if you wish.

Robot Lawn Mower FAQs

Robot lawn mowers can cope with minor lumps and bumps; however, any large holes or ruts should be filled in with topsoil or top dressing so the mower does not get stuck. You may also want to consider looking at our best lawn mowers for uneven ground if you decide that your lawn is too uneven for a robot mower.

To ensure your lawn is ready for use by a robotic lawnmower you should first cut it to about 7 cm. Then remove any small obstacles under 10 cm such as stones, hosepipes, garden toys and string.

Robot lawn mowers require very little maintenance. They do not need to be emptied, nor do the grass clippings need to be cleaned up. The trimmings are so small that they can be left to nourish your grass. The blades of your lawnmower are replaceable, and most manufacturers recommend replacing these yearly to keep the mower producing a nice clean cut.

Robot lawnmowers come with a host of safety features. They have high-tech sensors that turn the blades off if an object is nearby or the machine is picked up. This means they are very safe to use. However, to be extra secure, you should keep an eye on children and pets when using the mower. You could also program it to mow at a time when children and pets are not in the garden.
