Mower Type and Power
The Einhell is a cordless lawn mower powered by an 18V Power X-Change battery system. This battery-powered cordless setup allows mowing without mains cables, improving convenience for small to medium gardens where running a lead would be awkward. As with cordless mowers, mowing time is dependent on battery charge, so longer sessions may require battery planning. The mower uses a brushless motor, which can support consistent control during use. Overall, it prioritises mobility by trading plug-in convenience for battery management.
Cutting Width and Deck
A 30cm cutting width defines the mowing deck of the lawn mower. It suits edging and routine grass cutting in smaller areas rather than large lawns, because the deck covers a limited area per pass. The mower also offers 3 cutting heights, allowing the blade position to be adjusted for different grass lengths, which typically requires an even, overlapping mowing pattern. With a 25L grass box, the deck is designed to manage grass clippings efficiently, although frequent emptying may still be needed for thicker growth.
Lawn Size and Collection
With a 30 cm cutting width, the Einhell is typically best suited to smaller or medium lawns, because each pass covers a limited strip of grass. For larger areas, more overlapping passes are needed to finish evenly, which can increase mowing time. Collection is handled via a 25 L grass box, so clippings are contained during mowing rather than left on the surface. This helps keep the lawn tidy and reduces cleanup afterward, though the grass box can fill sooner on thicker growth, so it may need emptying during longer sessions.
Ease of Use and Storage
For day-to-day operation, the lawn mower is set up for basic cordless handling, using an 18V battery system to reduce the need for cords around the lawn. It features a 30cm cutting width to keep manoeuvring straightforward on smaller areas, and grass collected as cutting ends up in a 25L collection box. To start a session, the mower is handled like other cordless units, with the box checked before mowing. For storage, it fits in a shed or garage, but the battery and charger must be kept separately, and the three cutting heights are adjusted quickly between passes.
Who Is This Lawn Mower For?
The Einhell GE-CM 18 is for people wanting a cordless lawn mower solution for smaller lawns, with a 30cm cutting width designed to help with tighter turns and quicker passes. It suits homeowners who prefer a push mower and want to use the 18V Power X-Change battery system, with the battery and charger included as stated in the title. The 25L grass box supports grass collection without frequent emptying, although very large gardens may still require multiple stops because capacity has practical limits. It also fits users who want adjustable cutting heights, with three cutting heights provided.
Where to Buy in the UK
Shoppers looking for the Einhell in the UK will usually want to compare listings before buying, because availability can vary by retailer and bundle. This model is sold as a cordless lawnmower kit with an 18V Power X-Change battery, a 30cm cutting width, and a 25L grass box, plus a brushless motor and three cutting heights. When checking stock, buyers typically confirm the exact bundle contents, since not all listings include both the battery and charger. To find it, buyers usually look at Amazon UK, John Lewis, Currys, AO, Argos, and Mowers Online, then verify whether the battery and charger are included in the specific listing.
Frequently Asked Questions
Is the lawn mower worth it?
For keeping a lawn tidy with the least hassle, the Einhell (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 lawn mower?
This 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 the Einhell?
The Einhell GE-CM 18 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?
This lawn mower runs on a 18V 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 Einhell collect or mulch the grass?
The lawn mower 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 the Einhell 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 lawn mower is a typical example for its type; if space is tight, look for a compact-fold or upright-storage model like Flymo's EasiStore range.
