Are Robot Mowers Suitable For All Types Of Lawns?

Robotic lawnmowers have gained popularity among homeowners looking to reduce the effort required for lawn care and free up more time for leisure activities. These innovative machines promise to mow your lawn effortlessly, but it’s important to determine if they are suitable for your specific lawn requirements. Factors such as area output, lawn type, slope, and other features play a crucial role in choosing the right robotic lawnmower. In this article, we will explore the key considerations to help you determine if a robot mower is suitable for your lawn. 

Understanding Area Output

The first aspect to consider when evaluating robotic lawnmowers is their area output. Each model is designed to handle a specific area, and it’s important to match the capabilities of the mower with the size of your lawn. Manufacturers typically provide a maximum area performance specification, but it’s essential to consider real-world factors that can affect this number.

Factors that can impact the maximum area performance of a robotic lawnmower include:

  • Slopes: If your lawn has inclines or slopes, it can reduce the optimum mowing area by up to 30%.
  • Obstacles: Trees, flower beds, and other objects that the mower needs to navigate around can also impact its mowing area.
  • Weather Conditions: Rain sensors on some robotic mowers can cause them to pause operation during wet weather, further affecting the mowing area.
  • Variable Mowing Times: Some manufacturers calculate the maximum area output based on round-the-clock operation, while others limit the mowing time to a certain number of hours per day.
  • Lawn Type: Different grass types may require specific features or considerations when choosing a robotic lawnmower.
  • Garden Layout: Complex garden layouts with narrow passages or intricate designs may require a more maneuverable and adaptable mower.

It’s crucial to evaluate these factors and assess how they may impact the performance of a robotic lawnmower on your lawn.

Calculating the Required Area Output

Once you have considered the various factors that can affect the area output of a robotic lawnmower, you can calculate the required area output based on your lawn’s size and desired mowing times. To determine the required area output, you’ll need to follow these steps:

  1. Determine the size of your lawn using tools such as Google Maps or a measuring tape.
  2. Decide on the desired mowing times per week, taking into account your schedule and preferences.
  3. Calculate the required area output using the formula: Required area output of the manufacturer (in m²) = Lawn size (in m²) / Desired mowing time (in hours) x Operating time for the area (in hours) according to the manufacturer.

For example, if you have a 1,000 m² garden and want it mowed for a maximum of 40 hours per week, and the manufacturer specifies a mowing time of 120 hours for their model, the calculation would be as follows:

1,000 m² / 40 hours x 120 hours = 3,000 m²

Based on this calculation, you would need a robotic lawnmower with a maximum area output of 3,000 m² for your garden.

Features for Different Lawn Sizes

The suitability of a robotic lawnmower for your lawn also depends on its specific features. Different models offer various capabilities to cater to different lawn sizes and types. Let’s explore the key features to consider for small and large lawns:

Features for Small Lawns

If you have a smaller lawn, typically around 300 m², certain features become more important. Maneuverability and precision in cutting are crucial for winding gardens and narrow passages. Consider looking for the following features in a robotic lawnmower for smaller lawns:

  • Pendulum Suspended Mowing Deck: This feature allows the mower to adapt to uneven surfaces and ensures an accurate cutting result.
  • Low Noise Level: If you have neighbors or enjoy a peaceful garden environment, a low noise level is essential.
  • Cutting Width: Look for a cutting width of at least 18 cm to efficiently cover the lawn area.
  • Sensors for Maneuverability: Robotic mowers with sensors can navigate obstacles and tight spaces more effectively.
  • 360° Sensor for Obstacle Detection: A comprehensive obstacle detection system will help the mower avoid collisions and operate smoothly in smaller areas.

Features for Large Lawns

For larger lawns, typically exceeding 2,000 m², certain features become more important to ensure efficient and effective mowing. Consider the following features when choosing a robotic lawnmower for a larger lawn:

  • Pendulum Suspended Mowing Deck: Similar to smaller lawns, this feature ensures an accurate cutting result even on larger areas.
  • Powerful Li-Ion Battery: A large lawn requires a powerful battery to cover the area in the shortest possible time.
  • Cutting Width: Look for a cutting width of at least 56 cm to maximize efficiency while maintaining cutting quality.
  • 360° Sensor for Obstacle Detection: A comprehensive obstacle detection system remains crucial for larger lawns to avoid collisions with objects.

It’s important to match the features of the robotic lawnmower with the specific requirements of your lawn to ensure optimal performance.

Slope Compatibility

If your lawn has slopes, it’s essential to consider the mower’s capability to handle them. While some cheaper models can handle slopes of 20-25%, high-quality robotic mowers can tackle slopes of up to 45% or more. Look for models with wheels designed for off-road use, providing optimal traction to navigate slopes without slipping.

Additional Time-Saving Features

Apart from area output and specific lawn requirements, additional features can help reduce the time spent on lawn care. Consider these features when choosing a robotic lawnmower:

  • GSM Module: A GSM module enables remote control and programming of the mower through a mobile app, allowing you to manage the mower’s operation from anywhere and at any time.
  • Edge-Cutting Function: An edge-cutting function reduces the need for manual trimming along the lawn edges, saving time and effort.
  • Mulch Remover: Robotic mowers equipped with a mulch remover minimize the cleaning effort, as the clippings act as a natural fertilizer for the lawn.

These time-saving features can further enhance the convenience and efficiency of using a robotic lawnmower.


Choosing the right robotic lawnmower for your lawn depends on various factors such as area output, lawn type, slope, and additional features. It’s important to evaluate these factors and determine the specific requirements of your lawn before making a purchase. By considering area output calculations, features for different lawn sizes, slope compatibility, and time-saving features, you can find a robotic lawnmower that suits your needs and provides effortless lawn maintenance. Take the time to assess your lawn’s unique characteristics and make an informed decision to ensure optimal results and a beautifully maintained lawn without the hassle.
