I’ve tested dozens of lawn mowers over the years and, based on hands-on testing and real-world use, these are the cordless mowers I recommend for 2026. Each pick focuses on a specific need—best overall, small lawns, medium lawns, large lawns, and the best budget option—so you can match the mower to your garden and budget.

How I picked these mowers
I prioritise cut quality, runtime, build quality, battery ecosystem, and practical features such as mulching, collection capacity, and storage. Brushless motors, true battery interchangeability, and realistic run-time performance on longer grass are particularly important.
Top picks at a glance
- Best overall: Worx WG737E 40V (37 cm)
- Best for small lawns: LawnMaster 34 cm CLMF2434G
- Best for medium lawns: Greenworks 41 cm G40LM41K2x
- Best for large lawns: COBRA MX51S40VX (51 cm)

1. Best overall: Worx WG737E 40V (37 cm)
This model hits the sweet spot between power, runtime, and value. It uses two 20V PowerShare batteries to run as a 40V system, and features a brushless motor for quieter operation, improved efficiency, and longer life.
- Deck: 37 cm
- Power: 2 × 20V 4.0Ah PowerShare batteries (40V combined)
- Notable: True PowerShare battery ecosystem across Worx tools
- Best for: Small to medium lawns where build quality and battery flexibility matter
Why I recommend it: the brushless motor conserves battery under load, the dual-battery setup gives reliable runtime, and the build feels solid for the price. If you plan to expand to other tools, Worx’s genuine one-battery-fits-all approach maximises the value of every battery you buy.

2. Best for small lawns: LawnMaster 34 cm CLMF2434G
This is an excellent value pick for compact gardens. It’s extremely light at 8.6 kg, comes with two 4.0Ah batteries, and includes a rear roller for stripes plus a mulching plug.
- Deck: 34 cm
- Batteries: 2 × 24V 4.0Ah (Power share within LawnMaster range)
- Features: Mulching, rear roller, 6 cutting heights down to 20 mm
- Best for: Small lawns and tight storage spaces
Practical note: you get two powerful batteries in the box, which is unusual at this price point. The main limitation is a smaller ecosystem of tools compared with larger brands—but for basic garden tools it covers the essentials.

3. Best for medium lawns: Greenworks 41 cm G40LM41K2x
The Greenworks 41 cm model gives a wider cut to make mowing faster on mid-size lawns. It’s reliable, good value, and performs well even on slightly longer grass.
- Deck: 41 cm
- Batteries: 2 × 40V 2.0Ah (standard kit) — options exist with larger Ah
- Features: Mulching option, large 50 L bag, multiple cutting heights
- Best for: Lawns up to about 500 m² depending on battery choice
Practical note: choose the right battery kit when buying—Greenworks uses multiple 40V pack options; double-check you get the Ah and charger you expect. This mower is a reliable workhorse and a particularly good choice if you want a wider deck without stepping up to a self-propelled heavy model.

4. Best for large lawns: COBRA MX51S40VX (51 cm)
If you want petrol-like performance without fumes or maintenance, the COBRA MX51S40VX is a top pick. It has a heavy-duty steel 51 cm deck, a self-propelled drive, and a substantial 60 L collection bag.
- Deck: 51 cm steel
- Batteries: 2 × 40V Max+ 4.0Ah (supplied)
- Features: Self-propelled, collect/mulch/side discharge, vertical storage
- Best for: Large suburban lawns where speed and comfort matter
What to watch for: only one charger is included so you can charge one battery at a time. The mower’s weight delivers a petrol-like feel and excellent cut stability, making it a solid investment if you need capacity and performance.

5. Best budget option: LIGO 20V (33 cm)
For a very small lawn (under ~20 m²) and a tight budget, this lightweight 33 cm mower is hard to beat. It’s compact, easy to store, and often found for around £100–£110.
- Deck: 33 cm
- Batteries: 2 × 20V packs supplied
- Features: Lightweight and compact for small garden tasks
- Best for: Tiny yards, balcony lawns, or infrequent light mowing
Limitations: LIGO is not a large brand, so support and spare parts may be harder to source. For cutting a small lawn every fortnight, it’s a practical, low-cost solution that removes the need for cables and petrol.

Practical buying tips
Match deck size to lawn size
Deck width affects cutting time. Smaller decks (33–37 cm) are lighter and better for tight gardens. Larger decks (41–51 cm) reduce mowing time on bigger lawns.
Check the battery ecosystem
True power-share systems (for example Worx PowerShare) let you use the same batteries across many tools. This reduces cost and clutter. Other brands offer multiple voltage lines; double-check compatibility before buying extra tools or batteries.
Brushless motor matters
Brushless motors are quieter, more efficient, and longer-lasting than brushed motors—useful for conserving battery and avoiding heat under heavy loads.
Mulch, collect or stripe?
Decide what matters most. Mulching returns nutrients to the lawn, collection keeps lawns tidy, and rear rollers give the striped look. Many mowers combine two or three of these modes—choose based on lawn care goals.
Consider run-time versus battery capacity
Higher Ah batteries give longer run times but cost more. Two smaller batteries in sequence can be fine if you don’t want the bulk of a single large pack. Fast chargers reduce downtime, especially if you only have one charger.

Final thoughts
Cordless mowers have matured: you can now get petrol-like performance, long run times, and genuinely useful battery ecosystems. Choose the right deck size for your lawn, look for a brushless motor and realistic run-time figures, and favour a battery system you can reuse across other tools. The five mowers above cover most needs, from tiny lawns on a budget to large suburban lawns where comfort and speed matter.
If you want the quickest recommendation: for most homeowners I’d choose the Worx WG737E for its balance of power, battery flexibility, and build quality. For very small gardens pick the LawnMaster, and for larger lawns the COBRA MX51S40VX is the better, more comfortable option.
