Mower Type and Power
Designed as a cordless electric lawn mower, the lawn mower is powered by a 40V battery. This setup influences how and where it can be used, as it is intended for small to medium gardens where carrying a cord is inconvenient. The cordless format enables users to move around the lawn. It is also less suitable for very large areas if recharging takes longer than the task requires. Battery performance can vary as the battery charge level changes, affecting overall power dependability.
Cutting Width and Deck
Cutting width and deck design strongly affect how quickly the Flymo can cover grass and how it performs along edges. This cordless mower has a 30 cm cutting width, which supports steady mowing progress but may need more passes on broader lawns. The deck is designed for close edge cutting, bringing the blade path nearer to borders than a basic deck. Near walls or fencing, overlap each pass and turn slightly at corners to maintain a clean finish. In narrow strips, a slower pace helps avoid missed clumps.
Lawn Size and Collection
For typical home gardens, the lawn mower's 30 cm cutting width is best suited to smaller to medium spaces. Wider lawns may need more overlapping passes to cover the area efficiently. The 35 L grass box is designed for collection during mowing sessions, with the basket filling rate depending on grass growth and how dense the lawn is. For larger areas, mowing in shorter sessions and emptying the box regularly helps maintain consistent collection, and an even pace supports a more uniform result.
Ease of Use and Storage
After looking at how the 30 cm cutting width and 35 L grass box fit typical garden needs, it's worth considering day-to-day use and storage for this lawn mower. As a cordless The Flymo SimpliStore 340 Li lawn mower with a 40V battery, it avoids trailing cables, making it easier to move around the lawn. The close edge cutting helps when working near borders, although tight corners may still require careful passes. For storage, the smaller 30 cm class footprint generally suits garages or sheds, and the 35 L grass box should be removed for emptying and cleaning.
Who Is This Lawn Mower For?
Who is this lawn mower for? The Flymo is for people who want a cordless, lightweight lawn mower for small-to-average gardens, where a 30 cm cutting width is sufficient. Its 40V battery system is designed to remove the need for extension leads, and the grass box collection suits anyone looking for a tidy finish with less manual emptying. It is also aimed at users who want compact storage, with the emphasis on easy storage rather than a heavy, walk-behind style. For large lawns, a wider cutting width would be more suitable, as a 30 cm deck can limit cutting efficiency over bigger areas.
Where to Buy in the UK
Finding the lawn mower in the UK is usually easiest through major garden power retailers and online marketplaces that stock The Flymo cordless mowers.

Frequently Asked Questions
Is this lawn mower worth it?
For keeping a lawn tidy with the least hassle, the Flymo (a cordless mower) does the job with a 30cm cutting width. Whether it suits you comes down to your lawn size, terrain and how much effort you want to put in. Check the current Amazon UK price, as mowers are often discounted in season.
What type of mower is the Flymo SimpliStore 340 Li?
The lawn mower is a cordless mower. Petrol mowers are powerful and cordless for big or rough lawns; cordless battery mowers are quiet and low-maintenance for most gardens; corded electric are light and cheap for small lawns; hover mowers glide for edges and slopes; manual push mowers are eco and silent for tiny lawns. Choose the type for your lawn size and terrain.
What is the cutting width of this lawn mower?
The Flymo has a 30cm cutting width. A wider deck cuts more grass per pass so you finish faster - better for bigger lawns; a narrower deck is lighter and more manoeuvrable around borders and obstacles. Match the width to your lawn size and how tight the spaces are.
How powerful is the lawn mower?
The Flymo runs on a 40V battery. Higher battery voltage generally means more cutting power and run time; check the battery is included, as some are sold as bare tools.
Does the lawn mower collect or mulch the grass?
The Flymo SimpliStore 340 Li collects clippings into a grass box as you mow, so you get a clean finish and simply empty it when full. Check the grass box capacity against your lawn size to avoid frequent stops.
Is this lawn mower easy to store?
Storage depends on the design - many electric and cordless mowers fold or stand upright to save space, while petrol and ride-on mowers need more room. The Flymo is a typical example for its type; if space is tight, look for a compact-fold or upright-storage model like The lawn mower's EasiStore range.
