The mowing method : The McCulloch ROB R600 robotic lawnmower uses the principle of random mowing to do its job. Although it is initially thought that this method is not very effective, the fact remains that it is proven and that its results are quite satisfactory, because you will never see traces or annoying lines on the lawn. The only criticism of this method lies in the fact that the robot must do a lot of back and forth, and that the mowing is almost daily.

Robot Lawn Mower: How Does It Work?

The use of the robotic lawnmower is developing more and more nowadays because of its autonomy, its ease of use and maintenance, and its discretion. The only obstacle to the total generalization of its use seems to be the still high price displayed by this type of product. Anyway, you should know that its operating principle is relatively simple. So how does a robot lawn mower work?

The principle of tracking: The robotic lawnmower mows the lawn autonomously. To do this, it orients itself through your garden in a random or precise manner. The only factors that change this orientation are obstacles, the signal from a perimeter wire, or data transmitted by GPS.

The cutting principle: Unlike other mowers, the robotic lawnmower is not equipped with a waste collection system. To compensate for this lack, he uses a cutting technique called mulching.

The principle is also quite simple: the grass is cut at the tip and reduced into tiny pieces which immediately fall to the ground. This detritus constitutes a natural fertilizer to nourish and regenerate your lawn, it is grasscycling. However, this technique requires systematic, even daily, mowing of the lawn.

The principle of recharging: The robotic lawnmower operates on electricity. However, to be able to be fully autonomous, it must have a battery on board to store the accumulated energy.

There are several ways to recharge this battery: either by direct connection to a mains socket, which therefore requires human intervention, or by self-management by the robot which is placed on its charging station in the event of a low energy reserve, or either by recharging via solar panels placed on the shell of the device (recent technology).

How To Choose Your Robotic Mower?

The purchase of a robotic lawnmower is a significant investment. With an average price, you might as well not make a mistake in the choice and make it taking into account the right criteria. Indeed, it should not be believed that any robot is capable of mowing any lawn.

In reality, it all depends on your garden, the area to be mowed, its size, its complexity, its condition, but also what you expect from your robot in terms of options. Here are the criteria to be taken into account for a measured and adapted choice.

State Of The Garden

The criterion seems a bit vague since when we talk about a garden, we really have to identify a lot of characteristics such as the surface, the slope, the narrow passages, the recesses, the obstacles, the borders, the irregular surfaces, the water points, the stairs… We can still highlight the following data.

Area: You should know that each robot mower model is made to cover a certain maximum mowing area. So you need to measure your garden and include in your accounts any future sod installations you are considering. To be sure you have the best machine, choose a model with a mowing capacity 20% greater than the area to be mowed.

Tilt: The second important point is the robot’s ability to climb. A bad choice on this point and you will be in possession of a practically useless robot. You should know that a simple glance does not provide reliable information. A small calculation is necessary to have the exact percentage of inclination. To do this, divide the height of the highest point in your garden by the distance to the lowest point (slope length) and then multiply it by 100.

Areas: If your garden has narrow passages, parts that are difficult to access or several obstacles, a robot capable of handling such difficulties is more appropriate.

The Principle Of Progression

3 factors influence the automatic change of direction of the robot, namely obstacles, periphery cable and geolocation.

The robotic lawnmower with perimeter cable: Whether or not you choose a robotic lawnmower guided by a perimeter cable is a great choice. Indeed, such a cable requires preliminary installations even before the use of the mower, either by burial, or by using the stakes present in the equipment of the robot. This installation is more thorough than difficult.

The robot without perimeter cable: The models that do not require the installation of perimeter cable allow an easier and faster handling. However, it is preferable that a border or a hedge delimits your garden otherwise your robot will risk mowing your neighbor’s lawn as well.

Autonomy

You should know that mowing with a robot is longer than that carried out with a conventional mower. Already because of the way it mows, which is often random for most devices, but also because of the time it takes to recharge when its battery reaches a low level. Opt for a long-lasting mower if your garden area is huge. At the same time, favor Li-Ion batteries which are both quick to charge and durable.

Connectivity

More and more robotic mowers offer an application on smartphone or tablet (Android or iOS) so that you can control them. Although the controls are limited to walking, stopping, scheduling mowing, and reporting theft, having such an option is very useful if you want your robot to always work despite your absence. Connectivity can then be based on Bluetooth technology, WiFi or even the GSM network.

Maintenance And Upkeep

Depending on how often the robotic lawnmower is used, its blades must be changed, because worn blades severely limit the machine’s mowing capacity. So don’t forget to include the cost of these replacements in your budget. It is the same for the robot’s battery which must be changed after 2 to 5 years. Depending on the robot model you choose, the maintenance operation may be just a routine or a real obstacle course.
