Ease of movement

When it comes to movement, it couldn’t get any easier than when using this little beauty. It’s a robotic model so it moves all on its own. Simply turn it on and it goes off cutting the lawn before returning to its charging station when it needs a power boost. 

Smart features

This clever mower will adapt to different weather conditions, so it can tackle even wet grass. It will also adapt its cutting schedule according to how fast your lawn regrows. Now that's smart. Oh, and it will tackle sloped of up to 35 per cent.

Ease of emptying

There’s no bin to empty as the grass cuttings produced are so small that they simply disappear back into the lawn, acting as a natural fertiliser.

Reasons to buy
+Well priced for those on a budget+All you need for a small lawn+Environmentally friendly with zero energy use

If you like the idea of putting the effort in with a push lawn mower, get the Handy Hand push mower; it's the perfect choice as it doesn’t use any electricity or petrol – you just need elbow grease to get the job done.

Lightweight

While it’s certainly lightweight and can easily be lifted up with one hand, mowing the lawn is definitely harder without the benefit of electric power. This is fine if you only have a small lawn to deal with but it’s not advised for use on large gardens.

Ease of emptying

It is easy to empty, but the grass collector falls off a fair bit, which can be annoying. 

Scissor-like blade

The five-bladed cutting cylinder has an adjustable cutting height from 17cm to 43cm. The cutting mechanism is scissor-like rather than rotary – very gentle, which makes this the perfect model if you grow fine grass in your garden.

Ease of movement

For those who have a small to medium-sized lawn, the Flymo Hover Vac is a great choice, as it’s so light that it simply glides over the grass with minimum effort. As it folds down, so won’t take up much room.

Ease of emptying

The collector is quite small compared to other lawn mowers, which means you will need to empty it quite a few times during a grass cutting session. It's easy to empty as the lid simply flips off and it compacts the grass as it mows.

It's easy to push so long as your lawn is fairly flat, but you may need an extension lead if your lawn is medium sized or bigger.

This lawn mower is very lightweight – just 10 kilograms – and very easy to manoeuvre, not least thanks to its long, 20-metre power cord. Three cutting speeds  allow you to cut grass between 20 and 60 millimetres in length, which makes it versatile. 

Compact and easy to store

The handle fully folds down, and the mower is very easy to store away in a shed. 

Good sized grass bin

We liked the 26-litre grass collector bin on this lawn mower: it's not so small as to render the grass box useless, but not so large that it makes the mower bulky.

8. Worx 40V Cordless Lawn Mower

The best cordless lawn mower for larger gardens: impressive and affordable

Specifications
Best for: Medium and even larger lawns

Grass box?: 30L
Reasons to buy
+Generous battery life+Affordable+Neat edge-to-edge cut and handles longer grass well
Reasons to avoid
-Might not cut short enough for some-Instructions can be confusing

If you have a medium, or perhaps even a larger plot, little space to store a big mower, and just want something that will do a quick and easy job every weekend, then the Worx 40V Cordless Lawnmower is perfect. 

Great battery life 

The impressive double battery on this mower makes it suitable for lawn sizes that are normally just too big for cordless mowers that run out of power too quickly to cover the whole plot. 

Easy and safe to use

The mower is easy to start up – just attach the grass box, insert batteries, and you're good to go. The safety key means children won't be able to turn it on accidentally. The mower is easy to push and turn thanks to the good-sized wheels. 

Confusing instructions

It's a good thing that the mower is so easy to set up – because the instructions make it look harder than it is, so we advise not bothering with the manual.

What is the best lawn mower?

We reckon the best you can buy at the moment is the Bosch Rotak 32 electric lawn mower, as it’s a good price and is ideal for small and mid-sized gardens. It’s also great for tall grass and is easy to steer around obstacles.

Consider lawn size before buying your lawnmower

The size of your garden will determine which type of lawnmower is most suitable. It’s important to take into account the cutting width of the mower blades, as the wider the blade, the less time it will take to finish the lawn. Ultimately if you have a larger lawn it would benefit from a mower with a larger cutting width, such as 40 or 43cm, to make the job quicker and easier. 

What size blade do I need? 

The blade size is also know as the cutting width of your mower. Choosing the correct cutting width will allow you to mow your lawn efficiently and to move your mower around easily. As a general rule, choose the cutting width as follows:

  • A lawn of less than 50 square metres needs a blade width of between 30 and 34 centimetres
  • A lawn of between 50 and 150 square metres needs a cutting width of between 35 and 40 centimetres
  • A larger lawn of over 150 square metres will need a cutting width of at least 40 centimetres. 

Corded or cordless lawnmower?

Choosing between corded or cordless lawn mowers is dependent on your garden size: if you don’t have easy access to a mains power supply, cordless is the best option, a battery-powered lawnmower, which will give you freedom from power cables and allow you to roam across the lawn, while having as much power as a corded option. A lithium ion battery can provide enough power to last for up to 90 minutes, and in most cases will take an hour to charge. 

The downside to a cordless lawnmower? They may not quite have the power needed to tackle really long grass.

We have both corded and cordless models in our buyer's guide to the best electric lawn mowers

Choose the most comfortable lawnmower: size and weight

Try out a selection of lawnmowers to establish the comfort of the design in use and its weight. Look out for styles that you’ll be able to use without hunching over or stretching to reach the controls as this could cause muscle strain. The most comfortable lawnmower for women will also likely be a smaller, lightweight model. If you have limited mobility, a robotic lawn mower might be the best solution.

Choosing the best lawnmower for a finished lawn look

You should give consideration to how you want the finished lawn to look once it is mowed. Some lawnmowers include grass combs, which allow you to mow up to and over the edge of your lawn, without the need to always finish the edges with a separate tool. Choosing a lawnmower with an integrated rear roller will allow you to recreate the traditional two-tone stipe look too. Find out how to mow a lawn for best mowing results.

Choosing an eco-friendly lawnmower

The days of lawnmowers being regarded as gas-guzzling gadgets that emit toxins and create noise pollution are long gone. Today, the lawnmower has had something of an environmental makeover with battery-powered options now presenting a more eco-friendly option, reducing noise, fumes and use of non-renewable fuels. 

Grass boxes: are they necessary? 

Most lawn mower models include a grass box that collects the grass trimmings. The bigger the grass box capacity, the less frequently you'll have to stop mowing to empty it, and with particularly large ones, you might be able to leave the grass box unemptied between mowings as well. Just bear in mind that the grass box is one of the main things that affect the mower size: even the handles fold down, a large grass box will affect how you'll be storing your mower.

There is a newer breed of lawn mowers, though – look out for terms such as 'mulching attachment', although robot mowers will do the mulching as standard, as they're too small to have a grass box. Mulching isn't the same as simply leaving the grass trimmings behind: the mulching mechanism chops up the grass very finely and then sprinkles it over your lawn, which nourishes the new grass without choking it. As a rule, mowers that mulch are more expensive than traditional grass box models.

Robot lawn mowers: are they as easy as they look?

Robot lawn mowers are often presented as the easy, hands-off mowing option, and they are – but only after you've properly installed them. What not everyone realises is that the majority of robot mowers require you to bury wiring in the perimeter of your lawn/garden, which can be time consuming initially. There are some models that don't require pre-wring your lawn boundaries, but they will be more expensive (by at least a third) than ordinary lawn mowers. 

Lawn mower maintenance: our top tips 

Yes! Lawn mowers need maintenance: some of it you can easily do yourself, but sometimes it may also become necessary for a professional to look at it.

1. Most lawn mowers will need the undercarriage bowl cleaned every few months, as it can get caked with compressed grass and dirt. Scrape it our with a stiff wire brush and then hose it down.

2. Petrol mowers should be emptied after each use; old fuel that hasn't been changed in a while can cause problems, including the mower not starting up properly.

3. A clogged filter will also make your mower run less efficiently: these are typically made from paper or foam, and are easily cleaned out or replaced.

4. If you're noticing that, after a few years, your mower is tearing at the grass rather than precision cutting it, you need to get your mower blade sharpened. Don't try to do it yourself, though: take it to a mower repair specialist. 

Cylinder, hover or rotary? What type of lawn mower is best?

Different types of lawn mowers cut the grass in different ways, with some being more effective than others. A cylinder mower uses a rotary blade to scissor the grass, which works pretty well on small areas, but as soon as it rains, you’ll find it tougher to cut the grass with this type of lawnmower. Hover mowers are a little more robust and can cut their way through uneven patches of grass with ease. Rotary models are the most commonly purchased type of lawn mower, mostly because they feature one blade that can deal with long grass and uneven lawns, however, they're not amazing at giving that landscaped look.

What is the most reliable lawn mower?

To ensure that the lawn mower you pick will do the best job for you, you need to be sure that you've considered the size of your garden first. There's petrol, electric, push and cordless mowers to choose from. A petrol model is the best option for those with larger gardens; electric lawn mowers should be considered by those with small to medium sized gardens. Opt for a cordless version if you've a difficult shaped garden when it comes to plug sockets, and push mowers are the best option for those with small gardens as they're inexpensive. Be sure to closely check the specs above to select your ideal mower.
