The overall Which? test score is made up of the following star ratings, all determined by our rigorous lab tests.
How we test lawn blow
We rate the machine for how well it clears leaves from a variety of surfaces around your garden.
How we test patio blow
How well it blows wet, stuck-down leaves off a patio.
How we test border blow
How easily it blows leaves trapped in a flower border, without damaging your plants.
How we test leaf blower volume
Volume rates how noisy or quiet the blower is, 1 being loud and 5 being quiet. Vibration rates how much the blower vibrates during use. A low score means the vibrations are excessive and makes the blower more difficult to manage. Convenience takes into account of how bulky the machine is, how easy it is to carry around and how simple it is to empty the collection bag
How we test convenience
How easy it is to operate the controls and move the blower or blower vac around obtacles.
How we test battery
This takes into account how long the battery lasts on cordless leaf blowers and how long it takes to recharge.
