Best Robotic Lawn Mower in The Netherlands - Reviews and Comparison 2021

We picked the 7 best robotic lawn mowers in 2021 for your budget and use cases.

A robotic lawn mower looks nothing less than a fancy robot of a star trek show. Besides that whimsical look, people prefer it to have utmost convenience and comfort. All you got to do is install the device and select the options from settings as per your choice. Rest will be done on its own, including charging the bot mower!

A robotic mower is the most expensive lawn mower out of all types, and its price is justified by its features. Also, it may look like this independent piece of technology is best only for a large own, but that’s not true. It is very much beneficial for a lawn as small as 150m², especially if gardening is not your hobby.

Best practices for robotic lawn mower usage and care.

1. Features: Most important purchase criteria for a robotic lawn mower

1.1 Lawn Size

Take any type of lawn mower into account. The first thing that matters is the size of your lawn because not all lawn mowers all suitable for all kinds of lawn sizes. Moreover, you will not buy a Husqvarna Automower 315X to mow 250 m² area.

  • Small Lawn Area

A small lawn area usually consists of up to 350 m². And the ideal lawn mower for this size area is one that charges quickly, say, 45 minutes, and works for an or two. Moreover, it should not be expensive.

  • Medium Lawn Area

Any robotic lawn mower that can is designed for a garden size of 600 m² is best for medium size lawn. Any lawn mower that, after an hour of charging, is full again is suitable for medium-sized. Again, the aim is to get a robotic lawnmower that mows the entire lawn without charging it in between.

  • Large Lawn Area

A large lawn takes much more time than a small lawn, and their battery is the first thing you should check at the time of buying a lawn mower capable of mowing a 1000 m² area. If operating time is shorter, it will still handle your lawn, but sadly, you will have to charge it multiple times to get the job done.

All in all, battery size is not the only factor that is determined by lawn size. In fact, various features are influenced by the size of the lawn.

1.2 Lawn Surface

Besides lawn size, the surface type of the lawn also matters. For example, a robotic mower may or may not be suitable for sloppy or uneven terrains. Also, if your yard is not smooth, you may need a mower ideal for a large lawn than your actual lawn size. For example, a garden that is 350 m² on paper can be significant for a Bosch Indego S+ 350 Connect if the area has height differences between different points.

For lawns like this, a perimeter wire proves to be a saviour (discussed in point 1.).

1.3 Cutting Width

Wider cutting width simply means more area covered, and your lawn will be smoother in no time. It matters most when the lawn is large-sized. You need a mower that can cut maximum grass in one pass.

The simple rule is if your lawn size is large, you need a mower with a bigger cutting width. On the other hand, if you use a robotic lawn mower with a small cutting width to cut the grass of a large-sized lawn, it will take you quite some time.

Here is a table giving you a bird’s eye of lawn size and cutting width.

Lawn Size

Cutting Width

Small (up to 200m²)

30-34 cm

Medium (201m²-350m²)

35-40 cm

Large (above 350m²)

More than 40 cm

30-34 cm

Medium (201m²-350m²)

35-40 cm

Large (above 350m²)

More than 40 cm

1.4 Cutting Height

The cutting height feature determines the length of the grass, i.e. how tall or short it is. The height usually will vary between 20 and 70 mm. The medium size is between 35 and 45 mm, whereas the short lawn height range is 20 and 30 mm, and the pasture height is 50 to 60 mm. 

Lawn mowers never come with a fixed height because grass doesn't grow evenly irrespective of the lawn size. Also, their growth varies from season to season. At this point, the different height settings function come in handy. You can choose between 3 to 6 height options that most of the robotic lawn mowers come with. Moreover, a lawn mower bought for a small lawn will have fewer height adjustment options than a mower designed for large-sized gardens.

Moreover, a lawn mower bought for a small lawn will have fewer height adjustment options than a mower designed for large-sized gardens.

1.5 Blades

In a robotic lawn mower, there are either of two-blade systems. One is a multi-hinged blade system that is often a bit more fragile and unsuitable for shredding small things like twigs and pinecones. Then some models have a single sturdy blade, which takes small obstacles along with it. So choose as per your garden.

However, unlike standard mowers, robotic lawn mowers have small blades that are made for cutting only grass. Moreover, it comes with a safety function due to which they automatically stop if the mower is lifted or tilted.

1.6 Battery

When we talk about battery function in a robotic lawn mower case, we usually discuss battery charging time and the mowing time on a single charge.

Charging time

A lot can be derived from the title. It is about how long does a battery takes to charge. Here also, lawn size plays a crucial role. If the battery takes quite some time to charge and you have a small lawn, it is acceptable because chances are you might be done with the mowing in one charge.

However, in the case of a large lawn, you need a quick charging battery because, most likely, there will be no mower that will mow the grass of a large yard in one pass. And waiting for long between mowing sessions can be frustrating. Of course, the mower will indeed be doing the job, but if the machine needs any supervision, then you would undoubtedly prefer a quick battery charge.

Mowing time

Mowing time refers to the run time. For example, there are robotic lawn mowers that run for double the time they took for charging.

Type

Robotic lawn mowers run on lithium batteries as they have the longest working time. During charging, they indicate using different colours how much it is charged, just like it shows in the cordless battery vacuum cleaners. You can even check the battery charging status on the app.

Usage tip: Replace the mower's blades every year, especially if they are thin blades for their optimum working. Other models using heavy blades can be sharpened so that you can use them for a more extended period.

1.7 GPS or Perimeter Wire

A robotic lawn mower either works with a perimeter wire or runs entirely on GPS. 

Perimeter wire, also known as boundary wire, is used to set a boundary for the lawn mower. It is a thin cable that is laid around the lawn. The robotic lawnmower uses the magnetic field to recognize the wire and to know that it has reached the end of your garden. In other words, it will not go beyond the wire. The wire also helps in ensuring that the device follows the lawn’s edge and do not miss a thing. Moreover, it can also be extended to cover obstacles in the middle of the yard and keep the device away from those slopes or obstructions.

GPS robotic lawn mower models are much more expensive than perimeter wire models. It includes both GPS navigation as well as tracking. GPS navigation helps the mower find its way around the lawn, and GPS tracking makes it possible for the owner to determine the robotic mower's position and set up an anti-theft device. Besides high price and more time-consuming set-up, a GPS robotic mower only have benefits to offer. For starters, it ensures better orientation on the lawn and hence, better area performance. Next, it means shorter mowing times, less energy consumption and eventually, less wear & tear. Last, there is a better lawn appearance, no tracks in frequently used areas, even in a very complex lawn.

In our test, the first six robotic lawnmowers are supplied with “perimeter wire.”

1.8 Noise

We all know how much noise a lawn mower makes especially if it is a petrol lawnmower. It can wake up anyone out of its slumber! But the case of a robotic lawn mower is far from it. They are a type of mower that is actually on the quiet side. And with Silent Drive motors, Gardena offers the most silent robotic lawnmowers on the market (58 decibels).

But not all robotic lawn mowers are this silent. So, if you have neighbours or you prefer to mow your garden quietly, then checking the mower’s noise level is a must.

The noise level 58 dB is considered quiet, and 68 dB is quite noisy. The 58dB is usually fine to hear. For perfect comparison, refer to the table:

dB

1.9 Maintenance

Robotic lawn mowers need proper maintenance to work optimally. It is, therefore, suggested to replace the mower's blades every year in the case of the thin blades. The heavy blades can be sharpened to use them for a longer period.

The battery needs to be replaced after 3 to 5 years. Also, the underside and wheels need to be cleaned regularly so that the dirt doesn’t get stuck. However, the best thing about robotic mowers is that they can be cleaned using a garden hose as well!

1.10 Usage

A robotic lawn mower is used in two ways and, i.e. manual and programming.

  • Manual

In this, the mower continues to operate until the entire lawn is updated or it is evicted. This option helps in mowing a lawn in one go. On the downside, you have to stay close to switch off the mower, which makes you less free. And if the mower has to be recharged in between, it consumes time like anything.

  • Program

You can always program the robot or do the setting that your mower will work for specific hours on certain days. At the time of charging, it will come back to its charging station on its own and once charged, it will resume the work. You will be free from the job of looking after it.

1.11 App

A mower working in collaboration with the app sets a robotic lawn mower apart from other types. Every brand model comes with its own app. Using the app, you can change the in-built settings, interrupt the automatic mowing and give a new command. Plus, the app offers complete control over the device. However, a lawn mower with an app is not necessary because, typically, an app offers no more than what the menu on the mower already offers. Moreover, the connection usually works with Bluetooth, you also have to be close to it.

Another thing that also forms part of this feature is software. Periodic software updates keep a robotic lawn mower entirely up to date. Moreover, the smart things are rolled out later through an update for free so that you don't have to buy a new one in a few years.

1.12 Rain Sensors

Most of the robotic lawn mowers are weatherproof. Therefore, you can use them whether it’s a bright sunny day or raining. However, it is not right to mow the wet grass, and then the rain sensors feature comes in handy. The senor knows that during rain, the grass sticks together, and mowing becomes difficult. Therefore, the built-in rain sensors ensure that the device does not work when it rains. This way, you are sure that the device will not break or block due to large patches of wet grass. However, if, in any case, you want to mow damp grass, you can manually change the settings.

This is not it!

There are brands like Worx Landroid, which are a step ahead. It comes with a default setting under which the mower will resume the job after 180 minutes of raining, assuming that the garden must be dry now. But, again, you can change this setting anytime using the app.

1.13 Cradle

This refers to the charging function. When the device is not busy mowing, it is in the charger. The mower drives to it automatically and plugs in always to leave the station fully charged when it's time to mow.

1.14 Slopes and Obstacles

If your lawn has minor slopes and obstacles, you obviously don't want to buy a robotic lawnmower that can't handle them. Well, most robotic lawn mowers are equipped with minor obstacle detection like garden furniture, trampolines. However, if your lawn has more obstacles, it is good to identify them individually and then buy a robotic lawnmower.

Similarly, if your lawn is on a sloppy area or hills, you need some extra function. There are robotic mowers that can handle some degrees of slope. Usually, it remains 15% to 25%. However, if you can open your wallet a little bit more, you will find a mower that can handle even a 40% slope. Usually, hills and potholes on the lawn are often well within the angle of inclination capabilities of a robotic mower, yet it is best to check the specifications properly.

However, if your lawn has more obstacles, it is good to identify them individually and then buy a robotic lawnmower.

Similarly, if your lawn is on a sloppy area or hills, you need some extra function. There are robotic mowers that can handle some degrees of slope. Usually, it remains 15% to 25%. However, if you can open your wallet a little bit more, you will find a mower that can handle even a 40% slope. Usually, hills and potholes on the lawn are often well within the angle of inclination capabilities of a robotic mower, yet it is best to check the specifications properly.

1.15 Mowing Pattern

Most robotic lawn mowers follow a random route through the lawn until it hits the perimeter wire or the sensors detect that all the grass has been mowed. In addition, there are robotic mowers that do a reconnaissance round the first time they work. By doing this, they create an efficient line pattern which is then followed in future mowing sessions. Mowers also make spiral patterns when the grass is too high. You place the mower in the middle of the yard from where it works its way towards the garden boundaries in increasing circles.

There is an exception to the random mowing and i.e. Bosch robotic lawn mower "Indego". It creates a map of the lawn and systematically tackles the task.

1.18 Safety

The safety of the robotic lawn mower is of utmost importance as the device remain unattended on the lawn. Although the device is 100% safe, the manufacturers do ensure that the blades don't stick out. They are even quite far below the mower housing. In addition, the machine stops when lifted and turns off completely when placed outside the selected area.

A robotic lawn mower comes with various safety, and security features and the most common of them are discussed below.

  • The majority of mowers have a PIN code to protect them against theft. You need to enter the code for the device to work.

  • Then there are mowers equipped with an alarm system since the device remains outside, it is easier to steal. You can enable or disenable the alarm. When enabled, the alarm goes off after some time when the mower is lifted, and the PIN code is not entered.

  • Auto-lock safety function stops unauthorized access. It can also be enabled and disabled. It locks down the control over the robotic mower if buttons remain unpressed for 3 minutes. It can be unlocked only by entering the PIN code.

  • A robotic lawn mower is also equipped with a handful of sensors. A collision sensor or bump sensor, for example, helps in navigation, but it is also a safety feature. The sensor guides the device to turn away from the obstacle quickly. Tilt, lift, and turnover sensors stop the blades immediately when the mower is tilted, lifted or rolls over.

2. FAQ: Learn more about the details

2.1 How does a robotic lawn mower works?

A robotic lawnmower is like a computer that makes its own calculations about where it should mow. The boundary wire is connected to the charging station and forms a magnetic field: the lawnmower is only active within this field.

In addition, depending on the sensors available to the mowing robot, it does not collide with obstacles, switches itself off immediately when it is lifted and returns to its charging station when it starts to rain.

2.11 What is the right mowing direction?

If the clipping trail is forming on the right-hand side of the mowing swath, go for the clockwise pattern. If a clipping trail is forming on the left-hand side of the mowing swath, mow counterclockwise. However, for the long grass, it is usually recommended to cut in a counterclockwise direction. This is because long grass discharges substantial clippings, and mowing back over them can interfere with the blades and make it difficult for the robotic lawn mower to do the job effortlessly and correctly.

2.21 Can I use a robotic lawn mower to cut long grass?

If the grass is longer than 15 cm, it is advised to mow your lawn before installing a robot system. There are two reasons behind this.

Firstly, the mower may struggle to cut the long grass due to power limitations in the robot motor.

Secondly, even if it cut long grass, there will be substantial amounts of clippings on the lawn surface, which will not look good. Further, the mower will spread these cuttings evenly, which is good only when there is a small number of clippings and not otherwise.

2.23 Can I bury the perimeter wire?

Yes, the perimeter wire can be buried or pegged to the grass. A general piece of advice is that if you do not bury the perimeter wire, keep the blade’s cutting height a little bit higher, to avoid unexpectedly cutting or damaging the wire. Also, over time, the grass will grow over the top of the boundary wire and only in such case the cutting height can be lowered. However, if you bury the wire, it eliminates the risk of the wire being unexpectedly cut.

There is one downside though of burying the perimeter wire, and that's if there is a break due to some reason like rock movement under the soil or frost causing freeze-thaw, that will cause permanent damage to the wire. The more troublesome thing is that it is more difficult to identify the source of the break in the wire and undertake the subsequent repair. However, repairing is easy, so this one downside should not deter you from burying the wire.

3.2 How to maintain a robotic lawn mower?

Robot lawn mowers do not call for much maintenance or at least less than a conventional lawn mower. Here are some quick maintenance tips for a robotic lawn mower.

  • After installing the mower, inspect the blades and blade discs approximately once per week. Once you’re sure about the amount of wear, the inspection interval can be increased.

  • Use a stiff brush to clean wheels and the underside of the device. If this is not done, it will reduce the device’s ability to manage slopes, turn and change direction in wet or muddy conditions.

  • Check that the blades are moving freely and don't need changing. The life of the blades depends on several factors like the amount of time the lawnmower was in operation, the size of the working area, the grass type, the growth of the grass, the soil type, and the presence of debris such as pine cones, twigs and stones.

  • Before storing it in the winter season, ensure that the battery is charged and that the mower is stored upright.

3.4 How to take care of a robotic lawn mower in extreme conditions?

A robotic lawn mower is designed for all weather conditions providing they are normal. However, extremes of heat, cold, precipitation and wind will undoubtedly require you to take action to protect your robotic mower.

  • Heat

Extreme heat does harm the life and functioning of the mower’s battery. Direct sunlight is pretty harsh and can cause discolouration and damage to the external shell of the mower. Therefore, always keep the charging station in a shady area. So when the mower is charging or resting, it is far away from direct sunlight. You can also construct or purchase a robot lawn mower garage or shelter to protect it from direct sunlight.

  • Cold

Grass usually grows when the temperature is above 10°C. Therefore, when the temperature drops below 10°C during autumn, you can bring the mower into a winter storage area. Whereas, in the springtime, when the temperature is above 10°C consistently, you can bring it out again to begin cutting the grass as it grows.

  • Wind

Robotic mowers are heavy devices, with even small models weighing a minimum of 5 to 6 kg. However, in the event of a storm, there are high chances of it being blown by the wind when it is in operation or when it is docked with the charging station. Moreover, high winds may cause flying debris to hit your mower, thereby causing damage. Therefore, during high winds or storms, please keep it in a sheltered area.

  • Rain

The same procedure should be followed in the case of heavy rain as you followed in the case of heavy wind. Robotic lawn mowers are waterproof, and usual rainfall will not impact their functioning. However, in extreme rain, which could cause flooding, we don’t think anyone would like to see their robot lawn mower floating down the garden. In this condition also, we would advise keeping the mower in a sheltered and dry location.

  • The SILENO city lawn mower is ideal for smaller lawns (up to 250m²), delivering high performance and offering convenient mowing.

  • It is fully automatic. Just enter the lawn size, desired mowing days, and preferred start time on the GARDENA Bluetooth® App on your smartphone. The mower will see the rest.

  • It will make a schedule and do the job without any fuss.

  • Using Bluetooth function, you can control the device from up to 10 m away.

  • Due to the quiet motor and noise levels at only 57db(A), you and your neighbours will not even notice that your robot is in action.

  • With the help of the CorridorCut feature, the robot mower cuts grass even in narrow spaces and tight corners of just 60 centimetres width. Also, the function navigates your robot mower out of tricky dead ends.

  • Guided by SensorControl, the robot evaluates the situation as to how often the lawn needs a trim, setting off the best frequency in line with grass growth.

  • It is a weatherproof robotic lawn mower. It will cut grass whether it is raining or shining. However, we do not suggest cutting wet grass as it doesn’t give the best finish or results.

  • Also, it notices if the ground is frozen or too frosty, and the robot stops the action until the ground has thawed. 

  • The loop wire indicates to the lawn mower which area of the lawn should be mowed. Similarly, the boundary wire directs it reliably and fully automatically around all mowing areas. 

  • After doing its job, it will come back home to the charging station on its own.

  • Even slopes of up to 35 per cent are no problem.

  • It can be cleaned easily with a garden hose. 

  • It also has safety features like an emergency stop button, auto-lock, PIN code, collision, tilt, lift, and turnover sensors.

  • It mows autonomously, giving you more time to focus on doing the things that you love.
