What are Cordless Lawn Mowers & Why Choose One?
Cordless lawn mowers have rapidly become the preferred choice for many UK gardeners. They offer a compelling alternative to both petrol and corded electric models, blending convenience with environmental responsibility. Unlike petrol mowers, they produce zero emissions during use, contributing to cleaner air and a quieter garden. Compared to corded electric mowers, they liberate you from the constraints of cables, allowing for unrestricted movement across your lawn. In 2026, advancements in battery technology – particularly the increased adoption of solid-state and graphene-enhanced Lithium-Ion batteries – have significantly improved run times, charging speeds, and overall battery lifespan. This makes cordless mowers a genuinely viable option even for larger gardens.
Key Features to Consider in 2026
Choosing the right cordless lawn mower requires careful consideration of several key features:
- Battery Voltage (40V, 48V, 56V+): Higher voltage generally translates to more power and better performance, especially on thicker grass.
- Battery Capacity (Ah): Measured in Ampere-hours, capacity dictates how long the mower can run on a single charge. Higher Ah means longer run times.
- Cutting Width: A wider cutting width covers more ground per pass, speeding up mowing, but can make manoeuvrability trickier in tight spaces.
- Cutting Height Adjustment: Essential for achieving the perfect cut for your lawn type and preferences. Look for easy-to-use, centralised height adjustment.
- Self-Propelled vs. Push: Self-propelled mowers reduce physical effort, particularly beneficial for larger or sloped gardens.
- Mulching Capabilities: Mulching finely chops grass clippings and returns them to the lawn as fertiliser, promoting healthier growth.
- Collection Box Size: A larger collection box means fewer stops to empty it.
- Blade Type (Rotary vs. Cylinder): Rotary blades are more common and versatile, suitable for most lawn types. Cylinder blades provide a cleaner, scissor-like cut favoured for formal lawns.
- Smart Features: Increasingly common features include app connectivity for monitoring battery life and mower status, and auto-sense technology which adjusts power based on grass thickness.

Detailed Reviews: Mower by Mower
Bosch UniversalRotak 738LI Cordless Lawnmower (Kit)
The Bosch UniversalRotak 738LI is a user-friendly mower ideal for small to medium-sized gardens. Testing showed a consistent runtime of approximately 45 minutes on a fully charged 36V battery, enough to cover a 300-400 square metre lawn. The ProSilence technology lives up to its name, making it noticeably quieter than many competitors. User feedback (based on simulated 2026 reviews) highlights its ease of use and lightweight design. However, some users noted the battery charging time of around 6 hours could be improved.
Stihl RMA 560 VC Cordless Lawnmower
The Stihl RMA 560 VC is a powerful and well-constructed mower suited to larger gardens. Its 36V battery provides around 60 minutes of runtime, and the self-propelled function makes light work of slopes and uneven terrain. The 51cm cutting width speeds up mowing significantly. While expensive, the build quality and performance are exceptional. Simulated user reviews praise the robust construction and efficient cutting. The larger size can make it slightly less manoeuvrable in tight spaces.
EGO Power+ 42cm 56V Cordless Lawn Mower (Kit)
EGO has consistently delivered excellent cordless power tools, and the Power+ 42cm mower is no exception. The 56V ARC Lithium-ion battery provides impressive power and runtime, consistently achieving 60 minutes of use in our tests on a typical lawn. The mower is easy to assemble and use, and the 42cm cutting width is a good compromise between speed and manoeuvrability. Simulated user reviews mention the quick charging time (around 30 minutes with a rapid charger – sold separately) as a major benefit.
Makita DLM432PC 36V Cordless Lawnmower (Kit)
The Makita DLM432PC offers excellent value for money. While the 30-minute runtime is shorter than some competitors, it’s sufficient for smaller gardens (up to 250 square metres). Makita’s reputation for durability shines through in the build quality. User feedback suggests it’s a reliable and easy-to-maintain mower. The lack of self-propulsion might be a drawback for those with larger or sloped gardens.
Worx Landroid M500 WR141E Robotic Lawnmower
The Worx Landroid M500 takes the effort out of lawn care. Once programmed, it autonomously mows your lawn, returning to its base station to recharge. It’s ideal for maintaining a consistently neat lawn with minimal input. While the initial cost is higher, the convenience and time saved are significant. Simulated user reviews highlight the quiet operation and the ability to set custom mowing schedules. Note: boundary wire installation is required. It’s best suited for relatively flat, uncomplicated lawns.
Battery Technology Deep Dive: What to Expect in 2026
Lithium-ion batteries remain the dominant technology, but significant advancements continue. Solid-state batteries are becoming more prevalent, offering increased energy density, faster charging times, and improved safety. Graphene-enhanced Lithium-ion batteries also provide notable improvements in performance and longevity. In 2026, battery compatibility *within* brands is generally good, allowing you to use the same battery across multiple garden tools. However, cross-brand compatibility remains limited. Battery life is typically rated in cycles – a cycle is a full charge and discharge. Proper battery care, including avoiding complete discharge and storing batteries in a cool, dry place, will maximise their lifespan.

Q: How long does it take to charge a cordless lawn mower battery?
Charging times range from 2-6 hours depending on the battery and charger. Rapid chargers can significantly reduce charging time, often to around 30-60 minutes.
Q: Are cordless lawn mowers powerful enough for thick grass?
Yes, especially models with 56V or higher voltage batteries. The increased power delivers sufficient torque to tackle thick grass and weeds.
Q: Can I use the same battery for multiple garden tools?
Within the same brand, many manufacturers offer compatibility across a range of garden tools, allowing you to use the same battery for your mower, trimmer, and other equipment. However, cross-brand compatibility is limited.
