Choosing a robotic lawn mower is not simply a matter of buying the model with the largest advertised mowing capacity. Your lawn area is the starting point, but slopes, narrow passages, separate lawn zones, obstacles and grass growth can all affect which mower will perform best.
This guide explains how to match a robotic mower to your property, whether you have a compact residential lawn, a larger home section, a lifestyle block or an extensive commercial area.
Start by measuring the area that is actually grass
Robotic mower capacity is normally shown in square metres. Measure the mowable lawn rather than the total property size, excluding the house, driveway, gardens, sheds, ponds and other areas that will not be cut.
If your property plans are unavailable, you can estimate the lawn using an online mapping tool or divide it into simple rectangular areas and multiply the length by the width of each section. Add the sections together to estimate the total mowable area.
It is sensible to leave some capacity in reserve. A mower working close to its maximum area may need longer operating hours, particularly during periods of fast spring growth. Choosing a model with extra capacity can also help on complicated lawns.
Robotic mower guide by lawn size
The ranges below are a practical starting point. The final choice should also account for your lawn layout and terrain.
| Lawn area | Property type | What to look for |
|---|---|---|
| Up to 1,000m² | Small to medium residential lawns | A compact residential mower with enough slope capacity and the right boundary system for the garden layout. |
| 1,000–2,000m² | Larger residential sections | Good multi-zone control, dependable navigation and capacity above the measured lawn area. |
| 2,000–3,000m² | Large home lawns and smaller lifestyle properties | Wider coverage, strong navigation and traction suited to the lawn's slopes and complexity. |
| 3,000–5,000m² | Large or complex lifestyle properties | A high-capacity mower, with all-wheel drive where steep or difficult ground requires it. |
| More than 5,000m² | Commercial grounds and extensive properties | A professional robotic mowing system selected around the site, operating hours, terrain and fleet requirements. |

Good choices for lawns up to 2,000m²
For a larger residential lawn, look beyond area capacity and consider how the mower establishes its boundaries. A wire-free mower can be useful when you want to adjust mowing zones or create temporary no-go areas through an app.
The LawnMaster X5 Wireless Robotic Lawn Mower is designed for lawns up to 2,000m². It uses virtual boundaries rather than a physical perimeter wire and combines app-based zone management with all-wheel drive. It is a strong option for larger residential lawns, including properties with uneven ground or multiple areas to manage.
What about lawns up to 3,000m²?
As the lawn becomes larger, cutting width, navigation, runtime and the ability to organise different zones become increasingly important. The mower must cover the property consistently without spending excessive time searching for passages or returning to its charging station.
The LawnMaster X7 Wireless Robotic Lawn Mower is designed for lawns up to 3,000m². It offers wire-free navigation, all-wheel drive, multi-zone management and a wider cutting width than the X5. Browse our LawnMaster range to compare both models.
Large, steep or complicated lawns need more than extra capacity
Two properties with the same lawn area can require very different robotic mowers. A relatively flat, open 3,000m² lawn is easier to manage than a property of the same size containing steep banks, trees, tight corners, narrow connections and several separate zones.
For a difficult property, check:
- Maximum slope performance: Check both the maximum slope within the mowing area and the limit near the boundary.
- Drive system: All-wheel drive can provide better traction on steep or uneven lawns.
- Passage handling: Confirm that the mower can navigate the narrowest connection between lawn areas.
- Zone control: Separate work areas and adjustable schedules are useful when different parts of the property grow at different rates.
- Obstacle detection: This can reduce interruptions on lawns containing trees, furniture or other common obstacles.
- Boundary type: Decide whether a physical boundary wire or an adjustable virtual boundary is better for your property.
For extensive lawns, managed sites and more demanding applications, view our robotic lawn mowers for large properties and commercial use.
Should I choose the mower whose maximum capacity matches my lawn?
Usually, some spare capacity is preferable. Maximum-area figures are useful for comparing models, but real lawns are not identical test sites. Heavy seasonal growth, complicated shapes, slopes and restricted mowing hours can all increase the work required.
For example, if your measured lawn is close to 2,000m² but contains several difficult zones or steep areas, the best choice may be a mower rated above 2,000m². The aim is not to buy the largest machine available; it is to choose one that can comfortably maintain your particular lawn.
Residential or commercial robotic mower?
A high-capacity residential mower can suit many lifestyle properties. Commercial robotic mowers are intended for sites where durability, long operating hours, professional controls or fleet management are more important. These may include schools, business grounds, accommodation properties, sports facilities and public spaces.
Large commercial sites may also use more than one mower or a professional system designed around separate work areas. A site assessment is valuable before selecting equipment for this type of application.
Can a robotic mower handle a wet Manawatū lawn?
Many robotic mowers are designed to work in changing weather and are much lighter than conventional ride-on mowers. Because they cut small amounts frequently, they can help maintain the lawn without waiting for one large weekly cut. Their lighter weight may also reduce the deep ruts that a heavy mower can leave on soft ground.
Conditions, drainage and mower specifications still matter. Avoid treating any lawn as identical, and follow the operating and cleaning advice supplied with the selected model.
Get the right robotic mower for your property
The quickest way to narrow the options is to know your approximate lawn area, steepest slope, number of lawn zones and whether you prefer a physical wire or wire-free installation. Photos or a property plan can also help our team understand the layout.

Frequently asked questions
How much larger should a robotic mower's capacity be than my lawn?
There is no single percentage that suits every property. A flat, simple lawn may need less reserve capacity than a steep or complicated lawn with narrow passages and multiple zones. Choose around the lawn's total workload, not area alone.
Can one robotic mower maintain separate lawns?
Some models support multiple zones, corridors or secondary work areas. Whether the mower can travel between them automatically depends on the property layout and the mower's navigation system.
Do I need a boundary wire?
Not always. Some robotic mowers use a physical perimeter wire, while newer wire-free models can use virtual boundaries. The best option depends on signal conditions, layout, installation preferences and how often you want to change mowing areas.
What information should I bring when asking for a recommendation?
Bring the approximate mowable area, photos or a plan of the property, the steepest slope, details of narrow passages and the number of separate lawn zones. This makes it easier to match the mower to the actual site.
