You can visit here. We talk in detail about which Robotic lawnmower to buy!

Seeing so many varieties I thought I have to write something about these beautiful robotic lawnmowers! They are, not only a beauty, but they seem like a great investment if you don’t like spending hours tending to the lawn.

Let’s see in detail what these smart machines are about and what they can do for us.

What Is A Robotic Lawnmower?

A robotic lawnmower is an electronic device that automatically mows your lawn for you. These devices run on electricity and have a rechargeable battery. Accurate and quiet, these robots are capable of working even on rough terrain or on steep slopes.


In addition, thanks to the integrated GPS system. The robotic lawnmowers are able to draw a complete map of the garden so that they can improve their performance over time.

The market offers a wide range of models with more or less sophisticated features. And, although it is a relatively expensive device, its use is very widespread. Since it allows to always have a perfect lawn without effort, ideal even for those who tend to be away from home or who just don’t enjoy doing this task. Therefore, the purchase of an automatic electric lawn mower can be considered an excellent investment.

How An Robotic Lawnmower Works

The operation of an autonomous lawnmower is really simple. We simply have to charge the battery, program the device, and start it up. The garden robot will automatically move back and forth, keeping the grass at the correct height. Obviously, the product is sold with its attachments, this kit consists of:

  • Charging station: the base to which the robot will automatically return to recharge and, if necessary, start over.
  • External perimeter wire: wire that is placed around the perimeter of the garden to define the range of action of the robotic lawnmower. In some models, it is not necessary.
  • Guidewire: the wire that will help the robot to find the charging station at any time. In some models, it is not necessary.

How To Choose The Robotic Lawnmower?

There are several factors to consider when choosing a robotic lawnmower. Among the main ones, of course, are the size and morphology of your garden. Which will necessarily influence the choice of the best model for your needs. But there are many other variables that will help you make the best decision.

Next, we break down all these variables that you should take into account and know:

The dimensions of the garden

 “How big is the working area of ​​my potential robotic lawnmower?”

This is definitely the first question to ask before buying one of these devices.

In fact, large surfaces (more than 2000-2500 m2) require higher-priced products with greater autonomy. On the contrary, for smaller lawns, you can opt for cheaper products.
Other factors to consider in relation to the size of the garden are obviously the speed of the robot and the size of the blades.

Soil morphology and slopes

Not all gardens are the same. For a small grassy garden or a garden with slight slopes, it is possible to opt for standard models. Without too many pretensions, all robots support gentle slopes.
If, on the other hand, your garden has steep areas with slopes of more than 30 degrees, stronger models are recommended, preferably with a four-wheel drive.

To understand it better: Grass cut on a slope involves three types of risk:

  • The inability to face an escalation;

It is the first problem and must be faced with a robot with a well-positioned center of gravity! With wheels capable of “biting” the ground in the best way. And with traction power to allow the ascent;

  • The possibility of capsizing;

The second problem must be addressed with a well-thought-out wheelbase and balanced design. In addition, the most advanced products have a safety system that locks the blades in case of the robot tips over. This function is therefore very useful in the case of rough terrain. The same goes for sensors capable of recognizing irregularities in the ground.

  • The highest battery consumption;

The third problem should be addressed first with a larger capacity battery. But also with the correct positioning of the charging base. The advice is to place the base in the lowest area of ​​the garden so that during the return trip ( when the batteries are, they tend to be more discharged) there is less consumption. And the arrival of the robot to the rest position is guaranteed.

Obviously, these features will increase the price, but they are necessary for a user experience that does not disappoint. Different gardens require different robotic lawnmowers.

Lawn and mulch By A Robotic Lawnmower

What about cut grass? That’s another question that might come up before buying a robotic lawnmower. Among the products with or without a bag to collect cut grass, the best advice I can give you is to opt for a third way. The best garden robots have a mulching system.

For newcomers to these topics, mulching in a lawnmower consists of cutting, shredding the grass, and distributing it on the lawn without collecting it in a sack. The benefits of this cutting method are undeniable. The cut grass will act as fertilizer for the lawn, making it greener and more resistant.

Smart Functionality and Scheduling of Robotic lawnmower

The “intelligent” aspects are those that, added together, define the robot’s intelligence. In fact, they are not simple automatic lawnmowers. They can be activated with voice commands, their mowing strategies can be defined, mowing cycles can be programmed based on specific schedules. It can be regulated whether or not they leave the house at rain function and more.

The higher the intelligence of the robotic lawnmower, the lower the commitment of the person and the rarer their corrective actions. The advice is to rely on robots with a sufficient level of automation. So that the gain obtained is not only in terms of “fatigue” but also and above all in terms of time. The robot should completely free you from the idea of ​​having to take care of the garden. Because only then will you feel that it was worth the investment.

Robotic LawnMower

Most of the best robotic lawnmowers are programmable. Then you can decide what time to start and on what days of the week. This feature is obviously very useful in case of absence. The grass will no longer grow wild, but will always remain perfectly manicured and cut.

Recharge Of A Robotic Lawnmower

Consider recharging essential. I must say that there are two types of robots: fully automatic and semi-automatic. The former is capable of autonomously moving towards the charging base when the battery is low. Semi-autos, on the other hand, require you to move them to the charging station.

Obviously, fully automatic ones are advantageous from a comfort point of view. You don’t have to think about anything, the robot charges itself and starts to cut the grass independently.

Semi-automatic robotic lawnmowers, on the other hand, are a good option if your garden is made up of several separate areas. As perhaps there are paths that are perceived as obstacles by the robot. In these cases, you can also opt for a model with the multizone option. Here it is also good to consider what kind of garden the robot will have to take care of.

Perimeter wire or GPS?

Is it better to choose a robotic lawnmower with a perimeter wire or a robot without a perimeter wire?
This is not really a philosophical question. But rather a technical assessment where lawn size, lawn complexity, and budget all come into play.

The simplest, most accurate, and most economical solution is that of the perimeter wire. Although many steps have been taken to overcome this need, the Perimeter Wire is still the most useful tool for delineating the cutting surface and providing precise references to the robot.

Cutting in a seemingly random pattern, in different directions, ensures an even lawn throughout the garden. For more than 20 years, it has also proven to be the most reliable method of covering the entire area without leaving uncut grass. The reliability and precision of other technologies required for systematic cutting are not sufficient to guarantee a better result than the system with perimeter wire and random navigation.

The cable also has other specific functions:

  1. Delimits the boundary of the garden: it must be placed at a specific distance from the edge, guiding the gear stop exactly where the blade should go;
  2. Guides the robot to any remote start: (for example, when you want to start the robot from the opposite side of the garden, where it would otherwise be difficult to get to) and returns it to the charging base at the end of the mowing cycle;
  3. It surrounds obstacles that prevent the robot from colliding with them. With the risk of getting stuck in edges, artifacts, ornamental stones, fountains, young trees, or more.

The perimeter wire for robotic lawn mowers does not remain visible on the surface. It can be buried with special machines supplied by professional installers, or it can simply be laid in the garden via special plastic nails. In the first case, the wire will disappear immediately out of sight, in the second it will be a few weeks before you see it buried naturally.

Installation is simple and can be carried out by anyone on their own. But requires special attention to avoid giving incorrect indications to the robot. Otherwise, you can rely on a professional who will complete the operation in no time.

The alternative option is GPS, supplied as standard on the most advanced robotic lawnmowers. In this case, the cutting strategy is based on a map of the garden and the consequent choice of cutting areas based on the areas less frequented in the previous hours. Therefore, the route is not based on physical references, but on an analytical and statistical photograph of the routes taken.


Robotic Lawnmower: Do They Really Work? And other questions you can ask yourself!

The question that arises is: “If I buy a robotic lawnmower, can I forget to mow the lawn?” The answer is: absolutely yes. The best robotic lawnmowers are in fact a high-performance, precise and technological concentrate.

All you have to do is choose how to program the product and you will be pleasantly surprised by the uniformity of the cut. From the energy point of view, they are also highly efficient and non-polluting products, since, unlike motorized lawnmowers, they only use electricity.

Of course, the level of satisfaction is directly proportional to the quality and price of the product itself. For this reason, a little research is necessary to understand what your needs are and, consequently, choose the most suitable product to satisfy them.

How Much Does A Robotic Lawnmower Cost?

The price of robotic lawnmowers ranges from a few hundred to several thousand euros for high-end models. Obviously, there are several factors that influence the price, such as autonomy, the presence of traction wheels, the security system, the presence or absence of a guidewire and perimeter wire, etc.

What Are The Best Brands Of Robotic Lawnmowers?

There is no single answer to this question. In fact, you have to consider your personal needs and your budget. Among the best brands we find: Worx, Robomow , Husqvarna, Gardena Sileno City, etc.

What to consider when buying a robotic lawnmower?

The most important parameters to consider when making a choice are:

  • The maximum area the unit can handle;
  • The presence of safety sensors that block the blades in case of lifting;
  • The autonomy guaranteed for each recharge;
  • Silence and low emissions from the engine;
  • The precision of the cut, especially in the most difficult corners and along the edges of the lawn;
  • The ability to operate the mower remotely via an app.

Installing a Standalone Mower

The installation of automatic mowers involves simple initial operations. This cost can be easily eliminated by personal work that anyone can do with a minimum of effort.

Otherwise, you can trust a professional who can ask for around 100-200 euros (but it depends on the complexity of the garden and its surface).

These are the necessary operations:

  • A precise project on the operations to be carried out so that the robot can better express its skills during the cutting phase.
  • Laying the Perimeter Wire (by simply using Perimeter Nails) and the Charging Base
  • Adjust robot programs (cutting height, weekly cutting program, possible interaction with home automation)
  • When choosing the perimeter wire, it is advisable to strictly follow the instructions in the user manual of the chosen device. The diameter of the wire, the protective plastics, and the length of the perimeter of the garden are parameters that must be taken into account.

Robotic LawnMower

Attention: when verifying the cost of the robots it is advisable to evaluate if the necessary load base is included in the price. The cost of this element is usually not a minor issue. At the same time, it is recommended not to be scared by the global price. Because investing in a garden robot is really something that allows you to forget this aspect of housework, dedicating time and concentration to family, children, relaxation, work, or any other occupation. the lawn is in order, always, without having to take care of it in any way.

Maintaining a Robotic Lawn Mower

Maintenance costs are minimal. First of all, it is required to keep the garden clean. So that there are no stones, toys, twigs, sticks, or other elements that can affect the cut on impact with the blades. Checking the blades themselves, cleaning the robot! And cleaning the charging base is also required. It is to ensure the best performance and longest possible robot life. (A useful operation at monthly intervals and essential at the end of the cycle/season).

At the beginning of the season, it is advisable to use a scarifier to suck up the excess debris accumulated on the ground. Thus allowing the lawn to “breathe”, with less mold and greater health.

The maintenance time required is also minimal, while the availability of the components to be replaced depends on the popularity and distribution capabilities of the chosen brand. For this reason, it is advisable to trust well-known brands, avoiding later finding yourself without spare parts.

With a minimum of care, in fact, the robot can be guaranteed very long service life. And the availability of blades, batteries, wheels, and other items subject to wear and tear can offer us long-lasting quality service.

The disadvantage of Lawn Mower Robots: “The Edge Cut”

If it is not possible to have a garden with a leading-edge (for example, when the grass is delimited by a wall instead of a sidewalk at the same height as the lawn). The robot runs into an objective limit: the inability to cut the grass in the last few inches before the obstacle. This results in a small burden for the user, that is, cutting the edges with edgers or scissors. A small burden compared to the advanced time required to mow the lawn.

If, on the other hand, the grass can be surrounded by a small overhang! Then the problem is solved. The robot wheels are pulled up onto the frame and the grass is completely mowed, without any problem. So here is a curious little trick to adopt if you are considering an automatic lawnmower robot. Preparing your garden in advance will also save you the last effort you still need to have your garden always in order, 24 hours a day, seven days a week.
