Greenworks 40V Cordless Leaf Blower UK Review – Full Test

The Greenworks 40V sits at the entry level of the cordless leaf blower market. At around £130 it is cheaper than the Bosch AdvancedLeafBlower 36V and significantly less than the EGO LB5804E. That price point sets clear expectations – this is not competing with the premium options on raw performance, but on value and accessibility for gardeners who want a cordless blower without a significant investment.

We tested the Greenworks across the same autumn conditions as the EGO and Bosch to give a direct three-way comparison. This is the final individual review before our full best cordless leaf blowers UK comparison brings all three together. Here is the honest verdict on what the budget option can and cannot do.

Overview and first impressions

The Greenworks 40V is noticeably lighter and simpler than either of its rivals in this comparison – 2.1kg without battery, with a straightforward three-speed dial rather than a fully variable system. The build quality is adequate but a step below the Bosch and a significant step below the EGO – the plastic housing feels less substantial and the blower tube has a small amount of rattle that the premium options do not.

The design is functional rather than considered. The controls are simple and logical. The blower tube connects cleanly. The battery slides in easily and locks securely. It looks and feels like an entry-level tool, which is exactly what it is – and that is not necessarily a criticism if the performance delivers for the tasks it is designed for.

Specifications and scores

Performance testing

On dry leaves in a typical suburban garden the Greenworks performs adequately. Dry leaves on a patio or path clear at maximum speed, though it takes noticeably more passes than the Bosch or EGO to achieve the same result. The lower airflow figure (480 m3/h vs 660 m3/h for the Bosch) is evident in use – there is less authority behind each burst of air and the effective working width is narrower.

On wet leaves the limitation becomes more pronounced. Wet leaves on a lawn require multiple passes and the blower struggles with any pile of significant depth. Matted wet leaves on a path need to be broken up before the Greenworks can move them effectively. This is not a criticism in isolation – it is the expected behaviour of an entry-level tool at this price point. The honest assessment is that it handles typical garden leaf clearance from a small to medium garden adequately, and fails to handle the heavy-duty scenarios that this price point was never designed for.

Battery system and runtime

The Greenworks G40 battery platform covers the core garden tool categories – mowers, strimmers, hedge trimmers and blowers. It is not as widely supported as the Bosch Power for ALL or EGO systems but the range is adequate for a basic cordless garden tool collection. Runtime with the 2.0Ah battery is approximately 25-35 minutes at mixed speed – adequate for a small to medium garden in a single session.

The 4.0Ah battery extends runtime to 45-55 minutes. At the price of the tool itself, a large-capacity battery represents a significant additional investment relative to the blower – worth factoring in when comparing total cost against the Bosch, which offers better performance at a proportionally smaller battery premium.

• 2.0Ah battery: approximately 25-35 minutes at mixed speed
• 4.0Ah battery: approximately 45-55 minutes at mixed speed
• Battery compatible with Greenworks G40 range of garden tools
• Runtime is adequate for small gardens – borderline for medium gardens
• Battery cost relative to tool price is higher than premium rivals

Performance and limitations

The Greenworks 40V is an honest entry-level tool. It does not pretend to compete with the EGO or Bosch on raw performance, and in direct testing the gap is clear – particularly on wet leaves, where the lower airflow figure becomes a practical limitation rather than a spec sheet difference. For the right use case, however, none of those limitations matter: a small, regularly cleared garden with light annual leaf fall from shrubs and a small tree or two is exactly the scenario the Greenworks handles without complaint.

Final verdict

The Greenworks 40V does what its price suggests – it provides entry-level cordless leaf blowing capability at an entry-level price. In the right context – small garden, dry leaves, occasional use – it is perfectly adequate. Against the Bosch and EGO it is clearly outperformed, but at roughly half to a third of the price that is expected rather than a criticism.

The buying decision is straightforward: if your garden is small and leaf fall is moderate, the Greenworks saves you £50-120 over the Bosch and delivers an acceptable result for the conditions it is designed for. If your garden is larger, leaf fall is heavy, or you need reliable performance on wet autumn leaves, spend more and buy the Bosch or EGO. The performance gap in demanding conditions is simply too large to paper over with price alone.
