How does Robot Lawn Mower Work?

Robotic lawnmowers trim your grass for you without your involvement. You’ll start to see even more gardens equipped with one of these devices shortly. “How does it work?” is the most often asked question regarding my robot lawnmower.

Many thought we would be using robot lawnmowers by now, but they are fairly basic machines. It employs simple methods to guarantee that your grass is always neatly trimmed. Robot lawnmowers are explained straightforwardly in this article, which should give you a decent grasp of how they operate.

How does Robot Lawn Mower Work?


  1. Guide Wire

A guidewire is used to assist the Auto mower in finding its way back to its charging station.

  • Recharging

Using a signal or following the wires, the mower returns to the charging station.

  • Safety Sensors

When an Auto mower comes across an obstacle, it will halt, reverse, and travel in the other way as a result. When the handle is raised, the blades are turned off, and the machine shuts off.

  • Improved Lawns

The auto mower cuts a small amount of grass at a time, allowing it to keep up with the pace of development and organically fertilize the lawn.

  • Innovative Cutting.

Grass can be securely and quietly cut with the help of three different blades.

  • Boundary Wire

A conveniently buried wire which can be tailored to each yard’s layout is used by the Auto mower.


If you want an even, carpet-like cut, you’ll need to use an automaker. GPS is used on certain versions to improve performance.

What Makes Robot Lawn Mowers Work: The Four Main Systems.

  • An onboard engine and battery drive wind turbines.
  • Motor and battery power the mower’s wheels and chassis, allowing it to go around your yard.
  • A simple and low-power computer system that allows the mower to employ logic and algorithms to find the best route across your lawn to trim everything.
  • It may use a low voltage perimeter wire to define a boundary.

The Cutting System

Robot lawnmowers use cutting methods that are fundamentally different from those employed by traditional lawnmowers. For example, it is common for manual lawnmowers to be inefficient and employ high-powered cutting blades to speed up the grass-mowing process.

 Traditional lawnmowers need more powerful blades. As a result of this, and the fact that traditional lawn mowers are almost always powered by gasoline, they are significantly noisier.

Automated lawn mowing machines have smaller cutting blades and run slower than human mowers, allowing them to cut a lesser amount of grass each minute. Robot lawnmowers typically use one of two cutting technologies.

  • The robot lawnmower has a revolving disc with several cutting blades connected to it that may rotate freely. Razor blades provide a good comparison for the size of the blades used in these devices. These mowers have a small cutting diameter, but they are the quietest.
  • To improve the cutting breadth and, thus, the pace at which your grass is mowed, use solid cutting blades. If you don’t have a lot of space in your garage or don’t want to deal with the noise, they aren’t the best option.

It is because robot lawnmowers are meant to trim your grass considerably more regularly than a traditional mower.

The Chassis and Wheels

Robotic lawnmowers get a low center of gravity, which allows them to climb steep slopes with little chance of falling. However, the strength of the motor operating the wheels may restrict the capabilities of cheaper versions, while more expensive ones can handle slopes ranging up to 25 degrees.

If you have a hilly garden, dragging a traditional mower up and down may be a real pain. However, it may entice people with more difficult lawns to use robotic lawn mowers because of their ability to handle steep hills.

The tires of robot lawn mowers are intended to minimize damage to the grass under them. Because robot lawn mowers are regularly used, the wheels mustn’t damage the grass or leave tracks in it.

Low ground clearance and tucked-under blades limit the danger of damage from a robot lawn mower’s blades. In addition, onboard tilt and lift sensors make it impossible to reach the spinning blades beneath the chassis, either purposefully or unintentionally, without activating the automatic stop.

The brains of this operation

If an impediment or the boundary wire is encountered, the mower is designed to follow a series of simple instructions. Robot mowers use a variety of unpredictable and semi-random pathing strategies. On the other hand, robot lawnmowers are inefficient compared to the most effective method of cutting your lawn’s grass.

Robot mowers may run seven days a week and are almost undetectable while in operation; hence, some may see this design choice negatively. However, there are fewer systems to go wrong, and the cost of robot mowers is kept at a reasonable level by keeping things simple.

The robot lawn mower’s computer system also manages the mowing and charging schedules. It guarantees that the mower is cut when the owner desires and goes towards the charging station when necessary before resuming its tasks once it has been completely recharged.

The onboard computer also controls the safety measures. For example, due to its many safeguards, it is almost impossible to be injured by the blades of a robot lawnmower while it is in operation.

Boundary Detection

For the time being, all reputable robotic lawnmowers will use a boundary wire to identify the grass’s edge precisely. Before using your mower for the first time, you must lay this down along the lawn’s edge. However, fully, it takes 1-2 hours to set up, and you won’t see it after the grass grows over it. For a more discreet option, you may lay the perimeter wire approximately 20 centimeters into the earth.

Frequently Asked Question

Do robotic lawnmowers collect the grass?

All robotic lawnmowers are shredding mowers, implying they do not gather the grass and instead cut it into small clippings and spread it to decay, so the nutrients return to the soil. In addition, cutting in random patterns is no longer an option since the mower can now mow in straight lines.

How long do robot lawn mowers last?

If you buy a robotic lawnmower, you may expect it to endure for 15 to 20 years at most. Here are a few pointers to help you bring yours to the top of that range, if not even there.


With an Auto mower robotic lawnmower, you’re getting more than just a lawnmower—you’re guaranteed a freshly cut yard at all times. So instead of worrying about horsepower, cutting widths, or mowing engines, you can focus on mowing your lawn. You’ve been looking for a cutting-edge solution like an Auto mower for a long time!
