Quick verdict
Score: 9.2/10
Best for: Keeping your lawn tidy to suit its size and terrain
Not for: A lawn much bigger or rougher than this mower is built for
Bottom line: A capable lawn mower (cordless mower, 30cm cutting width, 18V battery) for a well-kept lawn.
The Einhell GE-CM 18 is a cordless lawnmower for small areas, running on an 18V Power X-Change battery platform. With a 30 cm cutting width, it is suited to tidy, manageable gardens, and the 25L grass box is designed to reduce how often it needs emptying during one session. It has three cutting heights for handling grass at different levels, but the battery is not included, so an extra purchase and charging time are required. Overall, it is best considered for spot mowing rather than larger lawns.

Mower Type and Power
Equipped as a cordless lawnmower, this lawn mower is designed for use with an 18V Power X-Change battery system. Being battery powered removes the need for petrol mixing and allows quicker start-up. The motor is brushless, which can support efficiency and reduced wear, while the cordless format still carries the typical runtime limits associated with battery mowers. It is sold as a "Solo" unit, so the battery is not included and a compatible Power X-Change 18V pack is required.
Cutting Width and Deck
With a 30 cm cutting width, the Einhell is set up for smaller garden areas where a wider deck is not required. This narrower deck means each pass covers a consistent band, which helps line up cuts and manage overlapping strokes more precisely in tighter spaces. Where longer areas are being cut, more passes may still be needed compared with models that have wider decks, as the mowing coverage per pass is smaller. The deck has three cutting height settings, allowing it to handle different grass lengths. A brushless motor is included.
Lawn Size and Collection
For lawns with a smaller footprint, the lawn mower's 30 cm cutting width helps keep mowing sessions practical, since a narrower deck requires more passes to cover the same area as wider models. It suits small to medium gardens where shorter, more frequent runs are realistic. The mower collects grass into a 25L grass box, which supports routine light grass clearing between emptying, though the box will need to be emptied as it fills. For patchy lawns, mowing in sections then repeating passes until the edges look even helps manage uneven areas.
Ease of Use and Storage
The Einhell is designed to be straightforward to operate as a cordless lawn mower, with a 30 cm cutting width for each pass, which supports easy manoeuvring around lawns and pathways. For storage, the cordless format helps reduce cable clutter, and the mower's compact footprint supports storage in smaller spaces. A 25 L grass box supports practical grass collection, since emptying the box stops the mowing process and cutting resumes after it is emptied. The battery specification is not stated, so charging and any battery swapping routines cannot be confirmed. Three cutting heights allow quick adjustments for different grass growth levels.
Who Is This Lawn Mower For?
Who this cordless mower fits best depends mainly on expectations about battery-powered mowing and the small-to-medium lawn size it can cover per pass. The lawn mower, with a 30cm cutting width and a 25L grass box, suits shorter sessions with quicker disposal when the grass box is full. It also fits yards where different grass lengths call for three cutting heights, and where compact storage matters. The mower is a good match for The Einhell GE-CM 18 users who already have an 18V battery, because a battery is not included. For larger gardens, more frequent cutting would be needed.
Where to Buy in the UK
For buyers considering the Einhell, the next step after checking it suits small-to-medium gardens and confirming the core features is finding a reliable UK seller. They should check major retailers including Amazon UK, John Lewis, Currys, AO, and Argos, and also compare specialist tool shops and trusted online marketplaces such as Plus Screwfix, B&Q, Toolstation, and Mowers Online. Stock can vary because this model is sold as a "Solo", so no battery is included, which affects total cost and compatibility. Before purchasing, they should verify the listing includes the 18V system, 30cm cutting width, brushless motor, and 25L grass box. They should also review delivery times, returns, and customer support, since these can differ between sellers.
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.
