Sovereign18V 4.0Ah Cordless Lawnmower 32cm

How we test grass cutting ability

We test each mower's ability to cope with cutting standard, long grass, rough grass, and wet grass lawns, judging how tidily it cuts the grass and what it's like to use it in different conditions.

How we test handling difficult terrain

Not all gardens are flat and obstacle free, so we test how the mower handles uneven ground, slopes, lawn edges, and how close to wall edges you can cut.

How we test grass collection

We assess how full the grass collector becomes before it needs to be emptied and how often we have to empty it to complete our cutting tests. We also assess how easy it is to remove, carry, empty and replace the grass collector.

How we test ease of use

We test how easy it is to manouvre the mower, carry and empty the grass collector, clean and store away the mower, adjust the handles and cutting height, and the comfort of the handles, controls and operating position.

How we test quietness

We monitor the noise levels when the mower is in use and give it a rating based on how quietly it runs.

How we test battery life

We test how long the battery lasts after a full charge, how much ground it can cover on a full charge, and how long it takes to fully charge the battery or batteries. The best cordless mower batteries usually last 30 minutes or longer.

How we test energy efficiency

We find out how much of an impact mowers will have on your bills by measuring how much electricity or fuel they use when mowing our test lawns.
