Who is the Mountfield Robotic Mower for?
The Mountfield robotic mower range is designed for homeowners with medium to large lawns who want a hands-off approach to grass cutting. The brand appeals to those already familiar with Mountfield's petrol mowers, offering a natural upgrade to automation. The S series targets lawns from 500 m² up to 2500 m², covering most suburban gardens.
Performance and Cutting Quality
Mountfield robotic mowers use a random navigation system guided by a boundary wire. Owner reviews consistently mention that the mowers cover the lawn evenly after a few initial cycles. The cutting deck uses a pivoting blade disc that handles grass up to 50mm in height. On flat lawns, the cut is clean and consistent. On slopes up to 25%, the mowers maintain traction well, though very steep banks may require additional boundary wire adjustments.
The 20V battery system on the S 2500 provides enough runtime for approximately 90 minutes of cutting, which covers the 2500 m² capacity when the mower returns to charge mid-cycle. Charging takes around 60 minutes. This is competitive with Flymo and Bosch models in the same price bracket.
Build Quality and Durability
Mountfield uses a robust ABS plastic housing that withstands typical garden wear. The wheels are large and treaded for grip on damp grass. The charging dock is weather-resistant, and the boundary wire is standard 2.5mm gauge. Some owners report that the wire connectors can be finicky to install, but once set up, they hold reliably. The mower includes a PIN lock and lift sensor for security, which is a standard feature across the range.
What to Check Before Buying
Before purchasing a Mountfield robotic mower, measure your lawn area accurately using a measuring wheel or satellite tool. Check the maximum slope gradient; the S series handles up to 25%, but if your lawn has steeper sections, you may need to split the area with additional boundary wire. Ensure you have a power outlet within reach of the charging dock, ideally near the center of your lawn for efficient coverage.
Mistakes to Avoid
A common mistake is underestimating the boundary wire installation. It must be laid flush with the ground and secured with pegs every 50cm. Another error is setting the cutting height too low initially; start at maximum height and lower gradually to avoid scalping. Finally, do not skip the initial mapping cycles; the mower needs 3-5 full cycles to learn the lawn layout.
Alternatives to Consider
If the Mountfield S 2500 does not suit your needs, the Flymo EasiLife 1200 is a strong alternative for smaller lawns with simpler layouts. The Husqvarna Automower 310 is a more premium option with GPS navigation and better app integration, though at a higher price point. For budget-conscious buyers, the Bosch Indego M 700 offers excellent self-learning technology for lawns up to 700 m².
FAQs
How long does the Mountfield S 2500 battery last?
The battery lasts approximately 90 minutes of continuous cutting, which is sufficient for a 2500 m² lawn with mid-cycle charging.
Can the Mountfield robotic mower handle slopes?
Yes, it can handle slopes up to 25% (14 degrees). Steeper slopes may require manual mowing or additional boundary wire adjustments.
Does the Mountfield mower work in the rain?
The mower is weather-resistant and can operate in light rain, but heavy rain may cause it to return to the dock for safety.
How do I install the boundary wire?
Lay the wire along the edge of your lawn, secure with pegs every 50cm, and connect to the charging dock. Allow 3-5 initial cycles for mapping.
Is the Mountfield S 2500 compatible with smart home systems?
It includes a basic app for scheduling and status checks, but it does not support Alexa or Google Home integration.
What is the warranty on Mountfield robotic mowers?
Mountfield offers a 2-year warranty on the mower and a 1-year warranty on the battery.
How often should I clean the mower?
Clean the underside and blades after every 10 cutting cycles to maintain performance and prevent grass buildup.
Can the mower handle wet grass?
It can cut damp grass, but wet clippings may stick to the blades. It is best to mow when the grass is dry.
Does the Mountfield mower have a lift sensor?
Yes, it includes a lift sensor that stops the blades and triggers an alarm if the mower is lifted.
What is the cutting height range?
The cutting height adjusts from 20mm to 50mm in three steps, suitable for most lawn types.
Our verdict
The Mountfield S 2500 is the best overall robotic mower for large lawns, offering reliable cutting and strong battery life. For smaller gardens, the S 800 provides excellent value with essential smart features. Both models deliver solid build quality and ease of use for homeowners seeking automation.
