Cordless Battery Powered Mowers
The Latest and Best
Tested and Reviewed by Fred-in-the-shed
Updated 28th June 2026
This page is for UK based gardeners
Here I am testing the Gtech Falcon, Flymo Mighti-Mo and Bosch Rotak 37Li
Battery powered mowers have been around for decades. They were originally designed for small lawns, or those far away from mains power.
But they were very heavy like this Webb battery mower I used 40 years ago.
The first version of the Bosch Rotak 37Li - tested in my garden from 2007 - 2019.
Today, thanks to new battery technology, cordless mowers can cut large lawns.
They are also safer as the lack of cable reduces the risk of tripping & electrocution.

Best Cordless Electric Rotary Mowers
Entry Level Budget Price Cordless Mowers Lawnmaster 24v Cordless Mower
The smallest cordless mowers available in the UK use 18/20v or 24v Li-ion batteries and are designed for small, frequently mowed lawns. They have either a 30, 32 or 34cm cut and an average run time of about 20 minutes depending on the battery size.
The best of the cheaper cordless mowers I can find is the 32cm cut 24v Lawnmaster model. Although basic in design it does have a new generation brushless motor for extra power. Buy Lawmaster Mower Direct from Manufacturer with a 10% Fredshed discount Use code Fred10 at checkout
Einhell also make one of the cheapest cordless mowers but is so basic it does not have a height adjustment lever and is very flimsy build quality. The slightly larger 33cm cut version has a height cut lever and is solidly built and a more sensible purchase.

The Lawnmaster 24v mower is the latest to enter the market and is enhanced by clever electronics and a brushless motor. The motor senses when the grass is thicker or longer and the battery then gives it more power. This feels a bit strange at first but works a treat and is a great improvement. The Lawnmaster comes with a 4 amp hour 24v Samsung Li-ion battery and a 1 hour charger. This 34cm blade mower is suitable for lawns up to the 300m2, IF you cut it regularly! The mower was easy to assemble, has a rear roller, mulching plate and is supported by a UK based distributor.

Worx
30cm, 34cm and 40cm cut models with rear roller
20v and 40v Versions using same batteries
This is the 30cm cut Worx WG730 being tested
on my lawn in Oxford. There are also 2 40v versions, that use two 20v batteries.
Worx 34cm cut cordless mower with two 20v batteries
Worx 37cm cut Cordless Mower with two 20v batteries Also a small 20v version, (30cm cut) using just one 20v battery
(but with large 5 amp hour capacity) for really small lawns.
Smallest 20v version, (30cm cut) using just one 20v battery for really small lawns All Worx mowers use the superb 20v Powershare batteries that are
available in 4 sizes and fit dozens of other Worx powertools. The 40v models are powered by two 20v batteries and you can chose
between 2, 2.5, 4, 5 or even 6 amp hour batteries.
If you chose the more expensive 6 amp hour batteries you will be able to cut three times the area you could with 2 amp hour batteries. So you can chose the batteries to suit your lawn, and use them in other power tools! The smallest 30cm model runs off one 20v 5 Amp hour battery and is suitable for a lawn up to 250sq metres.

Worx WG743
40cm wide cut for larger lawns
Yardforce 40v 32cm, 34cm and 37cm wide cut models with rear roller Yardforce are a relatively new Chinese company selling hi spec mowers at low prices.
I tested the Yardforce 32cm model which has a small rear roller and most of the features found on better models.
The body looks flimsy but is adequate for domestic use and the battery is top quality Samsung 40v
with 2.5 amp hours. I bought the original (not brushless) model with a grass trimmer and both function
well and passed their first year with flying colours.

Mini Cordless Mowers & Grass Trimmers with Wheels
British company Gtech have designed this superb 18v mini mower with a 10 inch metal blade. It is powered by an 18v battery from their garden tool range and also uses the same handle as their grass trimmer. The SLM 50 can be purchased complete with battery and charger or body only if you already have the grass trimmer.
The Gtech SLM50 has 2 cutting heights, set by moving each axle up or down. The cut is quite impressive and the battery should last at least 30 minutes after a 4 hour charge. The build quality is very high with a solid body and sturdy wheels. Gtech SLM50 with battery and charger
The idea started with Black&Decker who introduced a 4 wheel base for its 18v grass trimmer.
The Black & Decker uses the nylon trimmer line to cut the grass but the Gtech has a metal blade. I have used the B&D for years and love it versatility as a trimmer or mini mower. The replacement spools are cheap and easily available as is the 18v battery. The Gtech SLM50 is more robust and will cut longer grass better.

The biggest cordless mowers are made by Ego and use a unique 56v U shaped battery. Ego 56v cordless mower with 51cm cut The smallest cordless mower is made by Gardena and I am currently testing this one with its 22cm metal blade. Gardena HandyMower for use with Bosch 18v and Gardena 18v batteries

Best Cordless Mower ? The Bosch Rotak Li Range
BOSCH ROTAK - VERSION 2 - WITH GRASS COMBS & ERGO HANDLES
Bosch pioneered the breakthrough in battery technology for mowers. The Bosch Rotak Li launched in 2007 and was the first mower to have a lithium-ion battery. I had one of the first and it worked well for over 10 years In 2014 I visited the Stowmarket factory and was very impressed with the attention to detail and quality control measures implemented. Sadly Bosch closed the old Qualcast factory in 2019.
Here I am inspecting the Bosch Rotak production line in Suffolk. The first Rotak cordless mowers were top quality and lasted well.
DIFFERENT MODELS IN THE BOSCH ROTAK LI RANGE The Rotak cordless mowers were originally powered by one large (expensive) 36v battery. The 36v battery can be used in half a dozen other Bosch 36v garden power tools. The 2nd generation included the small 18v model the Bosch City Mower which has a 4 amp hour 18v battery, as supplied with Bosch Power 4 all products. The City Mower is ideal for lawns under 200sqm. The 3rd generation range of cordless Rotak mowers now only has 1 model using the 36v battery, the 44-750.
The 4 smaller mowers use less costly 18v batteries. The smallest 18V1-32-200 is similar to the CityMower and uses one 18v battery. The mid size mowers use 2 18v batteries doubled up to make 36v. These twin battery models come with a twin charger and mulch plugs. I think the twin battery is a good idea as the 18v batteries can be used in more products than the 36v battery. Bosch offer a 2 year warranty extendable to 3 years on their website. Bosch 18V2-38 with 2x 18v batteries Bosch 18V2-43 with 2 x 18v batteries
Bosch 36v Battery Options
The original battery was 2.6 amp hour and then increased to 4 amp hours as the models got larger. 36v 2 amp hour batteries are used in smaller tools in the 36v range. The largest Bosch Rotak uses a huge 6 amp hour 36v battery. Bosch 36v 44-750 without battery
Breaking News Bosch Discontinued all but one 36v Rotak Models.
Generation 2 Bosch Universal and Advanced Rotak Li and Generation 3 Models
The new mowers have quieter brushless motors. Other new features are handle height adjustment and a folding grass box. They are called the Easy Rotak, Universal Rotak and Advanced Rotak. Only the Advanced models have rear rollers for stripes. Bosch make great mowers but their model numbers are always confusing. Some model names relate to how many square metres they can cut on one charge, rather than blade width. So the Advanced Rotak 36-750 Li has a 36v motor and can cut up to 750m square of lawn. However most people don't know their lawn size in square metres and the amount of cutting that can be done largely depends on the length of the grass at the time. So if you need help choosing send me a low res image of your lawn or description.
If you are confused e mail fred@fredshed.com for advice on which model is best for you UK ONLY AND GIVE LAWN SIZE, BUDGET OR A SMALL IMAGE OF YOUR LAWN PLEASE

Flymo Cordless Mowers
This is the 40v 34cm cut Flymo cordless mower being tested on my lawn in Oxford. It was a good little mower, apart from its large and expensive battery, which failed. Most manufacturers are now moving to double up smaller batteries, that are cheaper to replace. Flymo are doing this AND using the Bosch PowerForAll batteries. Flymo are based in Northumberland, famous for hover mowers, and are now part of the Gardena and Husqvarna Group. Several brands now use the Bosch 18v battery platform - which I like and suggested years ago. Currently Flymo offer a bewildering and constantly changing range of cordless mowers. I hope to be able to test some soon. The new 2026 range includes the worlds first battery powered hover mower. Flymo EasiHover 36v Cordless Hover Mower

SELF-PROPELLED CORDLESS MOWERS
SELF-PROPELLED OR HAND-PROPELLED CORDLESS MOWERS ? Which to Choose? Self-propelled means self-driving - it powers itself along, unlike push-along or hand-propelled mowers. Self propelled mowers tend to be large and are great for wide open lawns but can be awkward to manoeuvre in tight spaces due to the drive controls and extra weight. Most Self propelled cordless mowers do not have a roller, the few that do tend to cost a lot more. Battery powered Self-propelled mowers will have at least a 36v Lithium-ion battery and often an even more expensive 60v or even 80v battery. If you lack some strength or agility then you may actually be better with a lighter weight battery mower that you push. The Bosch Rotak mowers are light enough for me to push from a wheelchair but strong enough to last 10 years. If you need a self propelling mower for a REALLY large lawn I would consider petrol until the price of large Li-ion batteries comes down. I tried the first self propelled battery mower in 2011, the CEL DM20. It had 2 separate motors, powered by a huge 17 amp hour lead acid battery, the size of a suitcase. Not surprisingly it was quite hard to handle.
Stihl RMA 443 TC is the largest of the 5 Stihl Cordless mowers One of the best self propelled cordless mowers is the Austrian made Stihl RMA 443TC that I am currently testing. This model uses a 36v Li-ion battery from the Stihl Pro range and uses one battery to power the drive and blade. It has 2 battery slots so you can keep a spare in place. Using both batteries will cut up to 450 sqm of lawn depending on how level your lawn is and how long your grass is. I should say that the batteries are made in China but by a company that Stihl partly own. This is the biggest of the 5 Stihl cordless mowers with its 19 inch (46cm) cut and the fantastic folding, height adjustable, mono handle. You cant buy Stihl mowers online as they are only sold from machinery dealerships where you get trained in using it and excellent service. You can buy other self propelled mowers online from the Hyundai, Cobra, Mountfield and Ego brands. Greenworks Cordless Mower 40 V 46 cm Cutting Width Self-Propelling
Or - have you considered a Robot Mower? I have been using these for over 20 years now and they are now viable for very large lawns.
The one I am with above has a V8 engine and was a promotional aid for Friendly Robotics. If you want my page about real Robot mowers use this link Robot Mowers

GTECH FALCON TESTED AND REVIEWED BY FRED
The gtech Falcon has easy sliding handle height adjustment and easy access to the battery compartment. The Gtech falcon does not have a rear roller to make stripes on your lawn. The Falcon has now been replaced with the CLM50, now white but otherwise the same. Gtech CLM50 42cm cut cordless mower
