What exactly is a mowing robot?

Similar to robot vacuum cleaners, mowing robots offer you a special comfort by mowing your lawn independently and without human guidance. These autonomous robot lawn mowers come in a futuristic design and relieve you of the tiring mowing work you have to do every week to keep your garden organized. Unthinkable a few years ago, today it is pretty much the norm for most garden owners.

Once the initial setup is correctly done and the device is configured, these little garden slaves will mow the entire lawn independently at the push of a button. Most models rely on a so-called boundary or orientation cables, which are laid on or under the lawn. They tell the robot mower which areas it should mow.

Should I buy a robot lawn mower?

In spring and summer time, grass needs to be mowed weekly if you want it to stay under a certain length. Depending on the size of your lawn, it is a time-consuming chore.

Whether you have vast areas of land or just a small back yard that needs to be mowed, a robot lawn mower will relieve you of this often tiresome gardening work. The bigger your garden is, the more your robotic mower will come in handy.

Even during your holiday, you will always have a perfectly mowed lawn. The only requirement for a robot mower is a suitable garden.

PROs
  • Completely independent
  • No noise pollution
  • Environmentally friendly, energy saving and efficient
  • Dete ts obstacles it may run into automatically and avoids them
  • Drives to its station and recharges automatically
  • Mown grass remains on the surface as a mulch
  • Theft protection through alarm system and PIN code, among other things
CONs
  • A bit more pricey compared to electric and push lawn mowers
  • Most models require initial installation. But it's a one-time effort
  • Not suitable for all lawns
  • Works better for shorter lawns

Is my garden suitable for a robot mower?

Robot lawn mowers these days can now handle many different types of gardens, as long as there aren't steep hills and without many obstacles such as bushes, trees, big rocks, and furniture.

Gardens with a bit of an angle, hills, sloping, or divided are no longer a problem for most models.

TIP: For large, winding, or sloping properties, you might want to use a higher-end mower that has been designed for such cases. Lower price point mower robots often have a hard time with challenging gardens and may not meet your expectations.

Are there mowing robots for sports fields?

As explained in the previous section, large, level surfaces are virtually predestined to be mowed by a lawn mowing robot. Sports fields and football pitches can, therefore, definitely be maintained automatically by a robot.

However, the majority of models are aimed at garden owners with lawns of up to 1,000 m². For sports fields, therefore, only professional mowing robots such as those from Husqvarna are suitable, which are designed for large areas of 1,000, 2,000 or more square meters.

Are robot mowers suitable for sports fields?

Yes!

As we mentioned earlier, large and even lawn surfaces work best for autonomous mowers. Especially sports fields such as golf courses and soccer pitches can definitely be maintained automatically by a robot.

However, most robot mowers out there are designed for garden owners with small lawns up to 10000ft2. To keep your sport field organized, you will need to invest in a professional robot mower that's specifically designed for heavy-duty use. Most Husqvarna robot lawn mowers will get the job done with their up to 20.000ft2 mowing capacity.

TIP: Don't forget that robot lawn mowers are basically mulch mowers, they don't have the capacity to collect the grass clippings into a bag. The cuts remain on the ground as a mulch or until you collect them.

How does a robot lawn mower work

It shares the same mowing principles with its gas, electric, and battery sisters. Sharp blades underneath the mower turn fast and cut the grass.  The only difference is that it finds its way around your garden via GPS or pre-laid boundary wires. Grass clippings remain on your lawn as mulch.

With the help of a boundary wire or GPS navigation, the robot knows in which area it should mow. A large number of sensors help it navigate and detect obstacles. An adjustable mowing plan can also be used to determine the days of the week and times.

How much does a robot lawn mower cost?

It totally depends on the size of your garden and the capabilities you want from your robot lawn mower. You could get a good robot mower for less than a thousand dollars for smaller yards ranging from 2500f2 to a maximum of 5,000ft2.

For bigger gardens, you should plan to invest accordingly more. Depending on the equipment and range of functions, the prices of lawn robots can vary considerably. The top models from Husqvarna, for example, are between 2,000 and 4,000 dollars.

Which lawn mowing robots are the best?

High-quality mowing robots with good equipment and software are available from manufacturers such as Husqvarna, GARDENA, WORX, and McCulloch. In our comparison table, you can compare the best models directly with each other and read their reviews by clicking on the read more button.

Are there mowing robots with GPS navigation?

Yes, there are.

Although most entry-level mowers lack the GPS navigation capability or control, a bit more expensive professional mowers for large gardens come with GPS in order to quickly map huge yards and mow them in the most efficient way possible. If you are not going to run your device on yards tens of thousands of square feet, you actually don't need to pay extra for GPS capability at all.

Using satellites, the area that needs to be mowed is measured, and the position of the mowing robot is determined. This enables the autonomous mower to optimize its mowing strategy to avoid mowing the same spot twice, wasting time and battery power in the process. The mowing result becomes even more even, and no un-mowed areas are left behind.

Another advantage of an integrated GPS module is the increased protection against theft. The communication module usually serves as a GPS tracker and can transmit the current location to the owner.

Can a lawn robot also mow on slopes?

Experts speak of a slope from a gradient of just 2%. If you own a hillside property, you should definitely determine the highest gradient before buying.

All models can handle hills of up to 15% without any problems. Most lawn robots can negotiate slopes between 25% and 35%, and some heavy-duty machines can mow up to 50% and more. It should be noted that the manufacturer's specifications are maximum values that the mower can only meet under optimum conditions. As a precaution, choose a robot mower model that is designed for even steeper slopes to avoid difficulties.

Are there also mowing robots without boundary cables?

Some robot mowers don't require burrying boundary wires under the ground. They detect the area that needs to be mowed with their so-called grass sensors. However, these devices are rather rare and only suitable for optimally laid out lawns, and they are known to fail quite often...

In the meantime, the first models are also on the market that allows navigation via GPS.

Pretty much all robot mowers these days also have crash sensors that detect steps, obstacles, and boundaries, for example. As soon it identfyies a wall, fence, or some other obstacle such as a bush, rock, or a piece of furniture, it automatically changes direction and continues to mow elsewhere.

Robot lawn mower patterns

With lawn robots, there are different strategies for driving and mowing the lawn. The most common mowing strategies are:

  • Free movement pattern: (random driving with occasional changes of direction). It's great when you're mowing your garden often, and the length difference before and after the mow isn't that big.
  • Riding in parallel lanes similar to conventional hand push and ride on lawnmowers
  • Spiral movement: The robot mows in an ever-expanding circle and keeps going until it reaches the edge.

Parallel drive mowing pattering usually gets the job a bit quicker since it doesn't mow the same place twice. I

However, the cutting pattern of the lawn looks more even and more natural with a free movement pattern. It is often the moving pattern the majority of robot mowers use.

Does a mowing robot need to be charged regularly?

Lawn robots are powered by their rechargeable batteries, and they need to be charged regularly. The good thing is, most lawn mowers just drive back to its charging station when it is running low on battery. So you, as the owner, do not have to worry about charging the lawnmower yourself.

Are robot lawn mowers safe?

All devices have various safety functions to reduce the risk of injury to a minimum.

When you're buying a robotic lawn mower, make sure it has a lift sensor that automatically stops the blades from running when the device is lifted, tilted or tipped over. Some other sensors and functions increase the safety of a mowing robot.
