Mower Type and Power
This lawn mower is a cordless lawn mower designed to run on an 18V Power X-Change battery. It is classed as a cordless tool, so it runs on its battery rather than mains power, which supports use around the garden without an extension lead. As the motor is described as brushless, it is intended to deliver efficient operation. Power availability is limited by the battery system, so longer sessions may require battery recharging, depending on use and battery capacity.
Cutting Width and Deck
With the mower type and 18V battery system covered, attention now shifts to the cutting width and the deck layout, since these directly affect how much lawn is covered with each pass and how clippings are handled. The Einhell has a 33 cm cutting width, delivering a moderate strip of cut per pass rather than a broad swath. Its deck is set up to feed clippings into the 30 L grass box, helping keep the mowing area tidy. The mower also provides 5 cutting heights, allowing users to match grass length, though the number of height settings limits the scope for very fine adjustment.
Lawn Size and Collection
For smaller to medium lawns, a 33 cm cutting width means each pass covers a limited strip, so mowing wider areas takes longer than on models with larger decks. The lawn mower is a cordless lawn mower with a 30L grass box, so grass collection depends on bag capacity as grass volume increases. With lighter trimming and frequent sessions, the grass box is less likely to fill quickly, keeping the workflow steady. With thicker, longer growth, the box can fill faster, so stopping to empty it becomes part of the routine to maintain cutting consistency. Lawn shape also matters, particularly around edges and obstacles.
Ease of Use and Storage
Ease of Use and Storage matter because they affect how often the mower can be used, not just how it cuts. The Einhell is cordless, which makes it easier to start and move around the garden than corded alternatives, and it removes the need to manage a power cable. Operation uses an included 18V battery system, so swapping or charging the battery forms part of routine use. A 30L grass box collection system supports quicker emptying during mowing sessions, although capacity will depend on how quickly the grass box fills in taller growth. For storage, the 33cm cutting width helps it fit in smaller sheds, and it is manageable on a shelf when fully dried.
Who Is This Lawn Mower For?
Who this lawn mower suits best depends on the type of garden work planned, because the lawn mower is a cordless mower built around an 18V Power X-Change battery system and designed with a 33cm cutting width. It is suited to homeowners with smaller lawns who want a lighter cordless option for regular mowing, since the 33cm deck supports efficient passes and manoeuvring around obstacles. It also fits users who can manage battery charging as part of routine mowing, because cordless operation depends on having a suitable battery available. The 30L grass box suits those who prefer collecting clippings, while multiple cutting heights help when grass levels vary slightly.
Where to Buy in the UK
Looking for the Einhell GE-CM 18 in the UK usually starts with major DIY and gardening retailers, because this is a cordless lawn mower kit that includes an 18V Power X-Change battery and a charger. Next, shoppers can compare online listings from big chains, local garden centres, and battery compatible tool sellers, since stock can vary. Buyers should confirm the package matches the 33 cm cutting width and 30L grass box, plus the claimed five cutting height settings, before paying. If availability is limited, they can search for the same model code, and verify brushless motor and kit contents.
Frequently Asked Questions
Is the Einhell worth it?
For keeping a lawn tidy with the least hassle, the lawn mower (a cordless mower) does the job with a 33cm 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 Einhell?
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 Einhell has a 33cm 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 Einhell GE-CM 18?
The 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 this lawn mower collect or mulch the grass?
The Einhell 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 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 Einhell 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.
