Finding the best cordless lawn mowers is essential for homeowners who want powerful lawn care without the noise, fumes or hassle of petrol models.
Modern cordless lawn mowers combine strong battery performance with lightweight design, making them ideal for small to medium-sized gardens.
We’ll review the top cordless lawn mowers, comparing cutting performance, battery life, durability, and value to help you choose the right mower for your lawn.
Top Picks
Greenworks 48V 36cm Twin-Battery Mower
You get near-petrol levels of power from a 48V setup, plus long runtime that can cover larger medium-sized lawns. It’s a solid performer with a good warranty, though a few users report isolated quality-control issues.
Overview
Greenworks’ 48V mower pairs two 24V batteries to deliver a performance level that can replace small petrol mowers for many homeowners. With a 36cm cutting width and a 40L collector it's positioned for medium lawns where longer runtime, robust cutting and a reliable warranty matter.
Features and real-world benefits
Practical notes and limitations
You’ll find it strong on typical UK grass and suitable for lawns up to several hundred square metres when used as intended. A minority of buyers reported faults such as misaligned wheels or stressed plastic parts on arrival; these seem to be isolated QC issues rather than systemic design failures. Greenworks’ multi-year guarantee helps mitigate risk, but inspect the unit on delivery and register warranties promptly.
Who this is for
Einhell 36V 43cm Power X-Change
You get a high-capacity cordless mower geared toward larger properties, with two included batteries and a roomy 63L grass box. It balances runtime and cutting width well but carries more weight than compact city mowers.
Overview
This 36V Einhell model is aimed at homeowners who need cordless performance on medium-to-large lawns. Its 43cm cutting width and large 63L collector let you cover more area per pass, while the twin-battery kit gives you the flexibility to run longer sessions or share batteries with other Power X-Change tools.
Key features and benefits
Practical insights and limitations
You’ll notice the difference when you compare this to small 30–34cm city mowers: covers more area and empties less often. Users report reliable cutting performance even on moderately overgrown grass, and the Power X-Change compatibility is a real convenience if you already own Einhell batteries. That said, you should be prepared for a heavier feel; if you need something ultra-lightweight for frequent short passes, a smaller model will be easier to manoeuvre.
Who this is for
If you prioritise cut capacity and runtime over minimal weight, this model is a sensible, practical choice.
Worx WG779E.2 40V Cut-to-Edge Mower
You’ll benefit from the cut-to-edge design that reduces trimming work and leaves neat striped results. It’s lightweight, easy to store and shares batteries with other PowerShare tools, though heavier mowing sessions can deplete the included batteries.
Overview
The Worx WG779E.2 is a practical mid-range cordless mower that emphasises finishing — cut-to-edge capability and a striped roller produce tidy results that reduce time spent with a strimmer. It runs on two 20V PowerShare batteries (sold together as a 40V system) and is designed for small to medium lawns.
What stands out
Practical considerations
The mower is user-friendly and quick to assemble, and many owners find it delivers a petrol-like cut for its class. However, battery size matters: the included 2.0Ah batteries are fine for smaller lawns but add extra batteries for larger or denser grass. If you value neat edges and convenience of battery sharing across other Worx tools, this is a strong contender.
Who this is for
Bosch CityMower 18V-32 Brushless
You get a compact, easy-to-handle brushless mower designed for small urban lawns with good battery interchangeability. It's lightweight and ergonomic but has a relatively small cutting width and a modest collector capacity.
Overview
Bosch's CityMower 18V-32 is designed with tight urban gardens in mind: compact footprint, a brushless motor and an ergonomic handle system prioritise comfort and control. It comes as a kit with a 4.0 Ah battery and a charger, making it ready to use out of the box for smaller lawns.
Key features and what you’ll notice
Practical use and trade-offs
If your lawn is under ~300 m² you’ll appreciate the lightweight handling and the ability to reuse Bosch 18V batteries across other tools. The trade-off is that you’ll make more passes than with wider mowers, and frequent emptying of the collector can interrupt workflow. Some users have noted the grass box feels flimsy and that assembly/handle folding could be improved, so inspect those parts if durability is a priority.
Who this is for
Greenworks 40V 35cm Twin-Battery Mower
You’ll appreciate the two included 40V batteries for uninterrupted mowing and the 35cm deck for medium-sized yards. The machine is light and user-friendly, though some assembly and plastic component fitment concerns have been reported.
Overview
Greenworks’ 40V mower is positioned at buyers who want a practical, battery-powered alternative for medium lawns. The package includes two 40V 2Ah batteries and a charger, five cutting heights and a 40L bag — a balanced kit for common garden sizes.
Features and benefits
Practical notes
The mower handles well for its size and many owners reported satisfactory cut quality with easy push-around operation. The included batteries are adequate for many medium lawns, but heavier or overgrown lawns will benefit from higher-capacity packs. Some buyers experienced assembly frustration related to handle clamps or small fittings — if you’re not mechanically confident, allow extra time to assemble and check components on delivery.
Who this is for
Flymo 18V SimpliMow 300 Lightweight
You get a very light, easy-to-store mower that performs well on small urban lawns and trims close to edges. Its compact collector and single battery mean it’s best suited to regular, short cuts rather than heavy-duty sessions.
Overview
The Flymo SimpliMow 300 is built for small, tidy lawns where light weight, silence and ease of storage are top priorities. Its 18V brushless motor and edge-cutting combs let you get close to borders while keeping the unit compact and manoeuvrable.
What you’ll like
Practical considerations
This mower excels when you cut frequently and keep grass short — frequent emptying of the collector is the trade-off if you let grass grow. Some users find the safety switch overly sensitive: if your grip shifts, the mower stops and requires a wind-down before restarting. For small households or city gardens where storage space is tight, its simplicity and battery compatibility are big advantages.
Who this is for
Einhell Power X-Change 18V 30cm Mower
You get a low-cost, light and compact mower that’s ideal for small lawns and occasional use. It’s an excellent entry-level option but the small cutting width and modest stock battery mean you may want extras for larger areas.
Overview
The Einhell GE-CM 18/30 is a compact, entry-level cordless mower built around the Power X-Change battery ecosystem. Its 30cm cutting width and 25L grass box make it best for small, well-maintained lawns or for users who value portability and a low upfront cost.
What it delivers
Use cases and caveats
If you maintain a small garden (roughly up to 150 m²) and already own Einhell batteries, this mower is a cost-effective, lightweight option. However, if you have larger areas or infrequent mowing intervals leading to longer grass, you’ll likely need additional batteries or a wider machine — the small grass box also means more frequent stops. Overall, it’s excellent value where compactness and price are primary concerns.

How to choose, use, and care for your cordless mower
When evaluating cordless mowers, focus on five core factors: power (voltage and motor type), battery ecosystem (availability and cross-compatibility), cutting width, collector capacity (or mulching options), and overall weight/ergonomics. Voltage gives a quick snapshot of capability: 18V systems are for small city lawns; 36–48V machines are for medium to large yards and heavier grass. Brushless motors improve efficiency and extend runtime.

Practical tips for everyday use
Maintenance and care (extend life and performance)
Budget vs. premium picks and common mistakes
Accessories and upgrades worth buying
With the right platform and a modest set of extras, a cordless mower will cover most homeowners’ needs cleanly and quietly. Choose based on your yard size and how often you want to empty the grass box: go Greenworks 48V for near-petrol power and longer runs, or Einhell 36V 43cm when coverage and collector capacity are your top priorities.
