Each owner of a country house tries to pay attention to the lawn. Some do it every day, others do it once a week. The cutting process takes a lot of time, because a person needs to prepare a tool, and then walk around the territory for an hour, and sometimes more. The owners of a large territory are even less lucky. Therefore, some manufacturers decided to automate this process by creating a complex technical device that does not require long wires and gasoline.
The editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best robotic lawn mowers for 2020.

Operation and purpose of the device
The external design of this device is practically the same as that of the standard manual versions. However, one element is missing - the handle. Otherwise, it is the same plastic case with a special shape, wheels and a cutting element that is installed at the bottom.
Despite this simplicity, the internal structure of the mechanism is rather complex. To control the robot, a microcomputer is needed, as well as several dozen sensors that will indicate the path and condition of the grass. The system also automatically detects the operating mode and stops if there is an unidentified object or animal ahead. Therefore, the device is completely safe, which makes it an actual purchase for a family with children.
The body is made as tightly as possible and from special materials. This solution reduces the risk of water ingress or damage from accidental mechanical stress. There may be three or four plastic wheels, depending on the equipment. For example, models are popular where there are two driving and one steering wheel. But there are also opposite options, where the number of front elements increases to 4. There is a small handle on the body, which is reassigned for transporting the robot.
Knives are of two types:
- Whole;
- With replaceable cutting element.
In the standard version, there are one or two such elements, but there are exceptions, for example, in models designed for high-speed mowing of lawns up to 100 meters or more. In such solutions, 3 or sometimes 5 knives are installed. Bevel adjustment is carried out centrally; for this, a special handle is used, which, when moving, changes the overhang of the knife.
The control panel is located in two versions: front and back. Where it will be located depends on the manufacturer's decision. For added safety, there is a protective cover at the top that prevents water or debris from entering. The panel can consist of buttons or have a special display. The latter is the most preferable, as it allows you to make settings many times faster.
Electric motors are used to set the robot in motion. Their dimensions are small, and they can also be brushed or brushless. In some cases, up to 4 of these motors are installed. However, this design is typical for all-wheel drive systems that operate in difficult areas with uneven terrain.The rotation or rotation of the device occurs due to the stopping of one rotating element.
Which battery is installed and how to charge it?
The device is powered by rechargeable batteries. There are 4 popular types of battery:
- Lead acid;
- Li-Pol;
- Li-Ion;
- Ni-MH.
Each of these options has a number of advantages and disadvantages. However, most of them function equally well. Models with lithium-ion batteries are more popular, since they are small in size and can go without power for a long time. If the charge cycle ends or the battery goes into self-discharge, then it will not be difficult for a person to replace an obsolete element with a new one. This is a convenient and practical solution.
The device is recharged without the direct participation of the user. All you need to do is place the robot on the docking station. In some models, the device automatically finds the base. As soon as the charge in the battery drops to a minimum value, the sensor indicates that it is time to head to the station. It is a charger and a long wire along which the device moves in case of a voltage drop. The product moves until it reaches the station, where it is fully charged.
Outdoor bases have a protective cover that prevents moisture from entering. In addition, there are models that are powered by sunlight, but their cost is too high.
Sensors
These devices provide fast and accurate navigation. They are installed inside the enclosure. The number of such elements depends on the capabilities of the device. Thanks to them, the robot does not rest against a tree or fence, does not fall into a river or a hole. Two devices are responsible for these actions: a touch sensor and a collision sensor. As soon as the device “senses” a threat, it turns around and drives in the opposite direction.
As soon as the robot hits an obstacle, the knives are automatically disabled. This prevents deformation. In addition, thanks to this sensor, children can safely be on the lawn, since the device will not harm them.
To perform emergency braking, use the red buttons located on the outside of the device. Also, emergency shutdown is triggered when a person lifts the device by a special handle. The outer casing of the robots has a guard for the cutting elements, which provides high protection if a person wants to check the condition of the blades.
The fence is a small cavity with special bumpers, inside which sharp elements rotate. But also some manufacturers produce a comb-shaped protective part.
Tilt and lift sensors help the unit to work in difficult terrain and not topple over when descending abruptly. Because light braking is applied, which prevents fast movement.
If a person buys an expensive lawn mower, then there is always a PIN code and alarm protection. This decision makes it impossible to steal such equipment. Therefore, the product will always be protected from encroachment by third parties. Some people go further and install a GPS tracker that notifies the owner of the location of the device if it is lost.
Mowing wet grass is difficult not only with hand-held mowers, but also with electric ones. Since it becomes more slippery after precipitation. Therefore, almost all robots are equipped with a rain sensor. If it has been raining recently, the device informs the microcomputer about it and is sent to the base.
Number of operating modes
Most often, the mower moves in a chaotic manner, so it will not be possible to predict the movement. This decision is not accidental, because thanks to it, the robot covers many times more space, while leaving no islands. In just a couple of work cycles, all the grass will be mowed, the lawn behind the device will be beautiful and neat.
However, in some models there is a mode that makes the technique move in a spiral or along the edges of the site. Modern options are able to independently analyze the site and create the necessary mode so that the zones are mowed sequentially.
Unlike the manual models, the robots do not have a mowing reservoir. However, it is not scattered over the entire plot, but is neatly spread over the lawn. Thanks to this solution, organic soil fertilization is created, which has a positive effect.
Self-management capability
Some robotic lawn mowers are equipped with manual controls and a timer. In the latter case, the person independently sets the program when and at what time the robot should leave the base and mow the grass. For manual control, a special application is used, which is available for Android and iOS. The main thing is that the device has Bluetooth. Such a solution makes it possible not only to monitor the work, but also to control equipment at a considerable distance.
In addition, some developers install special software that informs the owner about the location of the robot using notifications. Also, thanks to this, the user is able to change the settings of the mower without direct intervention. For example, movement, level of grass cut, etc. It is not necessary to leave the house, all operations take place at a considerable distance.
What to look for when choosing?
In order for the robot to serve for a long time and reliably, you should know what criteria should be paid attention to first of all.
- The area of the treated surface;
- The power of the device, there are three options: for small, medium and large haircuts;
- Battery capacity;
- Movement speed;
- Dimensions and number of cutting elements;
- Features of the area;
- The presence of auxiliary functions or programs for easy monitoring and control.
