Robot lawn mower with perimeter wire: strengths and weaknesses

The robotic lawnmower is the ideal solution for all those who love to have a beautiful lawn but have little time to devote to gardening. In fact, these cordless tools are nothing more than small machines capable of take care of cutting grass in a totally automatic way.

On the market you can find robots dedicated to different sizes and slopes, an important distinction to be made is between robots with or without a perimeter wire.

The robot without perimeter wire is the ideal choice for those looking for maximum comfort and who love technology. In fact, it is enough to program it once, using the garden home automation app, without having to install anything, and the machine acts in total autonomy, returning to its charging station once the grass has been mowed. The best known and most common, however, are robots equipped with a perimeter wire. They are particularly advantageous when the ground has numerous obstacles, as the presence of the wire avoids collisions with walls, steps and flower beds. Once the wire has been laid, which is buried, all you have to do is let the robot work, so if the garden area in which to cut is always the same, comfort is guaranteed.

What is the perimeter wire for?

Although they require more effort in the installation phase, robots with perimeter wire remain the preferred choice of consumers.

The perimeter wire is used for outline the work area of ​​the robot, avoiding that this can get stuck in tight corners or collide with obstacles.
The guide wire is then used to direct the robot when mowing the lawn, guiding it to the most distant areas of the garden, and to indicate the position of the charging station. To date, this method is safer than locating the area using satellite technology.

Wire installation

When we want to activate the robotic lawnmower for the first time, it is necessary to install the perimeter wire, which must be positioned all around the edge of the garden and large obstacles, such as hedges, trees and flower beds. It actually forms a fence that delimits the robot's grass cutting area.

The cable can be positioned in two ways: by fixing it to the ground with pegs, or by burying it.

The laying on the ground by means of pegs allows you to make changes and adjustments to the positioning even at a later time. The cable must run all around the robot's work area, taking care to leave some space from the obstacle, and secure it with a hammer and pegs. Usually after a few weeks the cable will blend in with the grass. This solution lends itself to little-lived gardens, it is not very suitable if we have pets that could move the wire.

If we consider keeping the robot in the garden and always entrusting it with the same cutting area, it is worthwhile bury the perimeter wire. This is also important because it saves us from having to be careful when periodically ventilating or weeding the lawn. The perimeter wire must be positioned all around the work area as for the previous method. The only difference is that the cable must be buried at a minimum depth of 1 cm and a maximum of 20 cm.

Why choose lawn mowers with perimeter wire

THE advantages of a robotic lawnmower with perimeter wire are many:

  • Convenience. Robot lawnmowers equipped with a perimeter wire have a lower cost than automatic robots, as they do not require dedicated technologies for mapping the work area.
  • Guaranteed technology. Robots with perimeter wire have dominated the business for years, so they are equipped with advanced technologies and proven effectiveness. They do not depend on satellite links or schedules.
  • Millimeter accuracy. The perimeter wire allows the robot to mow the lawn with surprising results, carefully avoiding bumping into walls or other obstacles.

Defects of the mower with boundary wire

Despite the great advantages it brings, the presence of the perimeter wire can sometimes also present some defects:

  • Installation of the perimeter wire. Unfortunately, placing a cable that delimits the work area takes time, sometimes even hours if the ground is particularly large.
  • It is not suitable for more than one lawn. In fact, if you need to cut more land close to each other, a robotic lawnmower without perimeter wire is better, as it is more comfortable and easier to move from one terrain to another.

Whatever the final choice, it is very important opt for a reputable brand. This is where STIHL's iMow line stands out: high-performance robotic lawnmowers, suitable for different types of terrain, reliable and equipped with integrated safety systems.
