Mower Type and Power
Einhell GE-CM 18/33 Li
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.
Greenworks
The Greenworks is a cordless rotary lawnmower powered by a 24V battery system. It has a 33cm cutting width, making it suitable for smaller grass areas. Being cordless avoids trailing leads, which helps around paths, beds, and garden edges. It is designed for a limited lawn area up to 140m², so it suits medium-sized gardens better than larger sites. The 24V battery setup supports daytime use with free movement around the lawn.
Cutting Width and Deck
Einhell GE-CM 18/33 Li
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.
Greenworks
With a 33cm cutting width, the lawn mower removes grass in relatively small swaths, which helps for tighter spaces like around beds and fences. On a typical lawn, that width means each pass covers less area than wider mowers, so mowing may require more overlapping strokes. The deck sits low enough for routine trimming, while the blade-driven cutting path stays consistent across the pass. For best results, overlap slightly to avoid missed strips, especially along edges. Where grass grows thicker, repeated passes may be needed to keep the finish even.
Lawn Size and Collection
Einhell GE-CM 18/33 Li
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.
Greenworks
For lawns up to 140m², the Greenworks is a sensible fit for small, manageable areas where cordless mowing helps avoid extension cords. With a 33cm cutting width, mowing progress depends on the number of passes required, which becomes more noticeable on uneven or overgrown lawns. Collection is handled by a 30L grass bag, so clippings are gathered during mowing rather than left behind. For larger gardens within this range, the bag can fill quickly, increasing how often stops are needed to empty it. Overall, it is best aligned with lighter, routine lawn care where grass growth is kept under control.
Ease of Use and Storage
Einhell GE-CM 18/33 Li
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.
Greenworks
Keeping day-to-day handling in mind, the lawn mower uses a 24V cordless battery system, which does not require an extension lead. With a 33cm cutting width, it is also easier to store on shelves or in smaller sheds. The 30L grass box is designed to collect cuttings in one place, helping reduce mess during breaks, but grass residue should still be emptied promptly, since storage and handling depend on keeping it contained.
Who Is This Lawn Mower For?
Einhell GE-CM 18/33 Li
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.
Greenworks
Who is this lawn mower best suited for? It is designed for smaller lawns, covering areas up to 140m² with a 33cm cutting width. A cordless setup suits users who prefer not to manage a power cable, and it is well matched to straightforward mowing on regular grass. It also suits those who want bag collection, as it includes a 30L grass box for collecting clippings. Larger gardens, uneven ground, or frequent deep cutting are not clearly supported by the stated specifications.
