Frequently Asked Questions

What type of lawn mower is best for my garden?

It depends on lawn size and how much time you want to spend maintaining it. Petrol mowers suit larger or uneven lawns needing more power, battery and electric mowers work well for small to medium gardens with easy access to charging, cylinder mowers give the finest cut for formal lawns, and robotic mowers are best if you want the job done automatically.

Should I choose a petrol, battery, or electric lawn mower?

Petrol lawn mowers offer the most power and no cable or charge-time limits, making them ideal for bigger lawns. Battery mowers are quieter, lighter, and require less maintenance, suiting most domestic gardens. Mains electric mowers are the most affordable option but are limited by cable length, so they're best for smaller, easily accessible lawns.

What's the difference between a rotary and a cylinder lawn mower?

Rotary mowers use a fast-spinning horizontal blade and handle longer grass, rough ground, and general mowing well. Cylinder mowers use multiple blades that scissor-cut against a fixed blade, giving a much finer, striped finish — better suited to well-maintained, formal lawns cut regularly.

Are robotic lawn mowers worth it?

Robotic mowers cut little and often, keeping your lawn consistently tidy with minimal effort once set up, and many now include GPS mapping and app control. They're a bigger upfront investment but save significant time over a season, particularly for larger or regularly used gardens.

What size lawn mower do I need?

As a general guide, a cutting width of 32-38cm suits lawns up to around 250m², 40-46cm suits 250-500m², and 48cm or above is better for lawns over 500m² or larger areas where self-propelled or roller models reduce mowing time.
