Mower Type and Power
With this lawn mower/38, the mower type is cordless. It is powered by the 36V Power X-Change battery system and has a 38cm cutting width designed for everyday lawn cuts. Being cordless removes the need to work within the limits of a mains cable, which makes movement around the garden simpler. The mower uses a brushless motor, which can help with efficiency.
Cutting Width and Deck
A 38cm cutting width sets the Einhell/38's deck for covering grass in manageable sections, which can suit mowing small to medium lawns where space is limited. The cordless 36V setup includes a deck designed to support mulching, so cuttings are processed back into the lawn rather than collected separately. The deck offers 6 cutting heights, allowing selection of a lower or higher setting depending on the grass condition. For best results, overlap passes slightly and set an appropriate height before starting to help avoid scalping.
Lawn Size and Collection
For lawn size, the 38 cm cutting width indicates the mower covers a moderate strip with each pass, making it more suited to small to medium lawns where maneuvering and repeat passes are manageable. The 45-litre grass container supports collecting cuttings during mowing, which can help when the grass is thicker. For larger lawns, mowing in sections can help reduce uneven patches and also limits how often the container needs attention. The mower is cordless, so moving between areas is straightforward. Heavier, longer grass may require more passes, especially around edges.
Ease of Use and Storage
The lawn mower's RASARRO 36/38 is designed for day-to-day handling. Its cordless setup means the mower can be moved around a garden without dragging a lead, which helps when paths and corners break up the lawn. The mower has a 38cm cutting width and a 45L grass box, making grass collection straightforward during typical sessions. It offers 6 cut heights, so adjusting for uneven patches is quicker than guessing. For storage, it is easier to tuck away than corded models, though battery and charger space must be planned. Mulching can simplify emptying routines, but bag checks still matter.
Who Is This Lawn Mower For?
This mower is for people who want a cordless 36V lawn cut with a mid-range 38cm cutting width, especially in gardens where paths and corners make dragging a lead impractical. It also suits homeowners who want grass recycling through mulching, since the mower supports that function directly. With a 45L grass box and six cut heights, it can be adjusted to suit different grass lengths, which helps when the lawn grows unevenly. It comes with two batteries and a charger, which supports regular mowing sessions across a typical garden layout. It fits users who are comfortable charging and swapping batteries between sessions.

How powerful is this lawn mower/38?
The Einhell/38 runs on a 36V 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 RASARRO 36/38 collect or mulch the grass?

Is this lawn mower/38 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/38 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.
