Main Features Of The Gtech CLM50 

We've dug further into the core specs of the Gtech CLM50 below covering their power and design features to see if this mower is right for you.

The Battery

The Gtech mower comes with a 48v lithium-ion battery which has a battery charge of 40 minutes, making it ample time for a small-medium sized garden. The battery can also be charged in just 60 minutes compared to other mowers which can often take a few hours to charge.

What We Think

For an average-sized small-medium backyard, we are quite impressed by the Gtech's running time, although it would likely struggle with larger gardens. 

We also like the handy lights which indicate when power is low or high so that you can prepare for the next charge.

The Deck & Blade 

One of the core features of this mower is its 42 cm cutting deck with an intelligent blade, this spinning blade has a smart system where it detects thicker grass and increases its speed from 2,800 rpm to 3,500 rpm.

The 42cm cutting width is ideal for mowing a medium garden quickly and its Omni blade single blade system allows the smart blade to stay balanced.

What We Think

This mower has a good durable blade system made from carbon steel and the type of metal blade smart sensor is great if you suffer from dense patches on your lawn. 

The single carbon steel blade also has few vibrations during use.

Cutting Height Adjustment 

Having a good range of cutting heights on your lawn mower is important since it determines how low it can cut your lawn height and how high it can handle the grass. 

This mower has a cutting height ranging between 20-80mm making it ideal for lawns with a longer grass height. The height can be adjusted in six different steps and uses a central height adjustment lever for ease of use. 

What We Think

Overall, the lawn mower has a good range of cutting heights, especially for the higher lawns, but it is missing a lower cutting height which many prefer on shorter grass starting from 10mm. The central adjustment lever is easy to set and use.

Grass Collection Box 

Having a large grass box on your mower is important so you can avoid having to empty your grass clippings so often and waste time. This mower houses one up to 50L which is ideal for a medium-sized lawn.

The grass bag is also easy to empty and can fold flat to save space thanks to the cloth design, it further has a full indicator to show when the box needs to be emptied. 

What We Think

A 50L size grass box is a good size to avoid too many trips, our only concern is that the grass box is made out of cloth which might not be very durable and break over time with usage.

Safety Features 

As with any mower, your model must have safety features, the Gtech CLM50 has a safety key that needs to be turned for the mower to be used, in addition, there is also a button that must be pushed for the mower to start at the same time.

What We Think

For a standard cordless mower, this model has the safety features you need to prevent accidental start-up and is still easy to use, avoiding a complicated start up system like petrol mowers.


In terms of the design, the Gtech mower boasts a sleek look with padding on the handles and controls within reach. The whole mower weighs 13.5kg and the handles can further be folded for easier storage purposes.

Thanks to the mower being cordless, you also have more freedom to move around with the mower without the risk of pulling a cord or tripping over it. 

What We Think

We love the design of this Gtech model and think it suits any homeowner who is looking for a simple compact mower for a medium garden. At 13.5kg, however, it's not the lightest of mowers out there considering its battery power, this is something to keep in mind if you will be carrying the mower from your shed.

How Do You Set Up The Gtech CLM50?

Setting up the Gtech CLM50 model is easy due to the fact it comes mostly pre-assembled. You will likely need to charge the battery upon arrival till the indicator shows four bars then all you have to do is attach the handle, attach the folding grass box and the battery. 

The battery will need to be slotted into the mower with the G logo facing upwards and the grass box hooks onto the mower up the protective flap which can be a bit fiddly to secure in place.

How Does The Gtech CLM50 Perform? 

When taking the Gtech out for a spin, you will need to turn the safety key 90-degree first to turn the mower on and adjust the cutting height according to the height of your lawn. 

To start the mower you then have to press the button and pull up the lever on the mower.

After taking the Gtech mower out for a few laps, you can immediately feel how the handy feature of the smart sensor works on the blade, feeling the mower speed up over dense thick grass, it also performs very quiet despite being so high powered. 

The grass box being 50L does make a difference to the number of emptying trips taken and the mower can cut right up to edges despite its larger cutting width.

We would overall say the Gtech CLM50 performs very well and is easy to use for longer periods thanks to its long running time, lightweight design and large grass box. The only thing we found missing was a rear roller to create those aesthetic stripes.

Is The Gtech CLM50 Easy To Use? 

In comparison to other cordless mowers, you do notice how simple this Gtech model is to use, with a straightforward set-up and easy to use controls. 

Its cordless design gives you more freedom without an extension cord and it's comfortable to use with its dual handles. It's the ideal mower to choose if you're after a start and go model.

Advantages & Disadvantages Of The Gtech CLM50

We would not recommend investing in this lawnmower if you have a very large garden, since we think the run time would be too small and the grass box would need emptying too often.
