Mower Type and Power
Einhell GE-CM 18/30 Li
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.
Greenworks
A cordless mower is what this lawn mower is, running on a 40V battery system rather than mains power. It is designed for lawn mowing without extension leads, which can make it simpler to move around the garden. Power is provided by the included 40V batteries, and the mower is intended to handle lawns up to 400m², according to the product listing. Because battery tools depend on charge level, longer mowing sessions may require planning for larger areas. Quick start convenience is likely to be a benefit.
Cutting Width and Deck
Einhell GE-CM 18/30 Li
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.
Greenworks
Cutting width is one of the main ways this mower affects how efficiently it moves through the lawn, and the Greenworks is rated at a 35 cm cutting width. With a deck sized to match that width, each pass covers a moderate strip of grass, so mowing faster usually comes from steady, straight overlapping strokes. A 35 cm deck works well in smaller or tighter areas where turning space matters, but it may take more passes than wider models on open ground. Deck performance also depends on technique, so uneven patches need slower movement to keep the cut consistent.
Lawn Size and Collection
Einhell GE-CM 18/30 Li
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.
Greenworks
For lawn sizing, the lawn mower cordless lawnmower (G40LM35K2X) is described for lawns up to 400m², setting expectations for how much grass it can handle in one session before collection becomes an issue. The 35cm cutting width covers a strip per pass, so larger areas require more overlapping passes to finish edging cleanly. Grass collection is handled by a 40L bag, so fuller-bag stops are more likely during longer, heavier grass collections. On small to mid-sized lawns, bagging suits routine maintenance, while very heavy clippings may require more frequent emptying.
Ease of Use and Storage
Einhell GE-CM 18/30 Li
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.
Greenworks
Ease of use and storage matter because the Greenworks is designed for regular lawn upkeep rather than long, complex setup sessions. It is cordless, with a 40V battery powering a 35cm cutting width, which avoids cable management. The mower's compact mowing size helps it fit in a shed or garage, and the grass box collects clippings to reduce mess when the box is emptied. Two 40V 2Ah batteries can simplify switching, though storage space is still needed for the batteries and the charger. Operation feels straightforward, with minor routine steps before each use.
Who Is This Lawn Mower For?
Einhell GE-CM 18/30 Li
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.
Greenworks
This mower suits people who want a cordless 40V lawn cut without dealing with a cable, particularly for lawns up to 400m². The 35cm cutting width is set up for regular garden maintenance rather than clearing very large plots, so heavier or overgrown lawns may need multiple passes. It is also aimed at households that prefer grass collection via a grass box, helping keep clippings tidier during routine mowing. Two 40V 2Ah batteries and one charger are included, making it a practical option for anyone storing a matching battery-powered tool set.
