Two cordless 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 two models that could leave you feeling underwhelmed, either because our tests show that they don't cut well or because they're tricky to use.
Why Which? lawn mower reviews are better
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.
- How long it takes to cut the grass.
- How well the mower collects the grass clippings.
- How neat it leaves the lawn edges.
- How smart the finished lawn is.
- Our experts also rate each lawn mower on how easy is it to use.
