This Best Buy is a great cordless lawn mower that can cut all types of grass well, and is quiet and easy to use. It can cover a lot of ground on one battery charge, although the slow charging time is a bit of a drawback. It's still a worthy Best Buy, though.

This Best Buy battery-powered mower is a real pleasure to use. It gives a very neat cut on normal grass and, despite being a light mower, leaves smart stripes on your lawn. It copes well on long and rough grass, too. The 30-minute battery life is plenty for lawns up to 300 metres square.

This fab Best Buy gives an average of 30 minutes mowing time, allowing you to cover 360 square metres with one full charge. It only takes one hour for the battery to recharge too. It cut all types of grass without fuss, and was manoeuvrable with a lot of power for a cordless mower.

This mower is a good choice if you want a cordless model that has the power to compete with a petrol lawn mower. The 45-minute mowing time is one of the longest of the cordless lawn mowers we've tested, and the battery only takes 30 minutes to recharge, which is quick compared to many.

Two lawn mowers to avoid

You can only tell if a lawn mower is any good by using it to cut grass in several different conditions. This is exactly what we do in our Which? independent lab tests. We cut short grass when it's dry and when it's wet to find out how well the mowers will cope with cutting your lawn, and try cutting lawns on sloping and uneven ground and right up to fences too. 

Not all lawn mowers are great. Here are three models including a cordless lawn mower that could leave you feeling underwhelmed, either because our tests show that they don't cut well or because they're tricky to use.

This corded electric mower may be cheap, but it’s awkward to use and leaves your lawn looking a mess.

This push mower is fine on short, dry grass, but can’t cope with long or damp grass and doesn’t collect the clippings well.

We review more lawn mowers than anyone else

Which? tests around 3,300 products every year, from washing-up liquid to cars. When testing lawn mowers, we measure how well each one cuts grass – from short, ornamental lawns to long meadow grass – time how long it takes to cut the grass, how well the mower collects the grass clippings, how neat it leaves the lawn edges and how smart the finished lawn is. Our experts also rate each lawn mower on how easy is it to use.
