Bottom line: A capable lawn mower (cordless mower, 38cm cutting width, 18V battery) for a well-kept lawn.
The Einhell GE-HM 18 is a cordless walk-behind cylinder lawnmower for smaller jobs, using an 18 V battery system and a 38 cm cutting width for efficient passes. It is positioned as an easy-to-handle option for tidy, regular cutting, with mulching and four cutting heights to adjust grass length.

Mower Type and Power
Mower type and power shape how this lawn mower is expected to perform in everyday grass cutting. It is a cordless, walk-behind cylinder lawn mower designed for manual guiding over the lawn surface. A cordless 18V setup depends on the charge available, so performance will vary with battery choice and grass thickness. With a 38 cm cutting width, it is suited to small to medium areas, where frequent, manageable passes help maintain an even finish.
Cutting Width and Deck
A 38 cm cutting width sets the pace for the Einhell. With a wider path covering more ground per pass, the stated width helps keep the cutting line consistent across the lawn. The deck layout supports a walk-behind cylinder style cut, and the mower includes 4 cutting heights, enabling adjustments for different grass conditions before returning to the same passes. For edging and tight borders, the 38 cm deck width may require careful steering, slower progress, and overlapping trails.
Lawn Size and Collection
With a 38 cm cutting width that helps define the mowing pattern, lawn size planning also matters for how well the lawn mower can keep up from pass to pass. The cordless cylinder mower is suited to moderate areas. For collection, the 45L grass box supports longer sessions before emptying, so mowing larger lawns can feel more steady. A practical approach is to work in overlapping strips, then aim the clippings into the box, adjusting the four cutting heights as lawn conditions change. For very large lawns, breaks may be needed.
Ease of Use and Storage
Ease of use and storage for the Einhell centres on its walk-behind, cordless design and the ability to get it ready for use between sessions. After fitting the 18V battery (not included), the mower is ready for pushing. It has a 38cm cutting width for covering ground efficiently, with a 45L grass box for collecting clippings. Cutting height is adjustable across four settings by changing the mower's adjustment positions. After use, it can be stored compactly, although the amount of space required depends on how much room is needed for handling and for storing the grass box safely.
Who Is This Lawn Mower For?
This lawn mower suits people who want a walk-behind, cordless 18V option for small to medium lawns, where a 38cm cutting width is enough to cover the area without repeated passes. It is a good match for those who value mulching, since clippings can be handled on the lawn rather than only collecting. The 45L grass box can help during longer mowing sessions by reducing how often it needs emptying, although capacity limits still apply. Simple height adjustment with 4 cutting heights makes it suitable for different grass conditions. For very large gardens, not stated.
Where to Buy in the UK
For UK shoppers, the lawn mower is the "Solo" version of the mower, so it is sold without a battery included. It should be sourced from retailers that stock The Einhell GE-HM 18's Power X-Change range, then matched against the product listing to confirm the 38 cm cutting width, 45 L grass box, four cutting heights, and mulching. A key point is compatibility with an 18 V Power X-Change battery and charger, if these are not already available. If the battery and charger are not included with the chosen item, buyers should ensure they are adding compatible Power X-Change components alongside the mower.
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 38cm 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 38cm 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-HM 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 offers mulching, chopping clippings finely and dropping them back to feed the lawn - no emptying, though it suits regular light cuts. Many mowers also collect into a grass box if you prefer a clean finish.
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.
