10 Best Robot Lawnmowers You Can Trust Reviewed [2021]

Thinking of buying a robot lawnmower? Your lawn could be forever grateful. Robot lawnmowers have come a long way and now they’re more reliable than ever.

It’s not just a question of saving time and energy–the right robot lawnmower can help improve the health and look of your lawn. It’s all to do with the precise, neat, and fussy way in which they work.

In this buying guide, we’ll explain how robotic lawnmowing works, review the ten best robot lawnmowers on the market, and show you what to pay attention to when shopping for one to make the right choice.

So, are you ready to pass on your lawn care worries to a robot?

How Does a Robot Lawnmower Work?

Robot lawnmowers have built-in sensors that enable them to mow around obstacles within an area bounded by wire. The wire is usually installed underground and comes in the package.

They essentially mow in a random pattern, not changing direction until encountering an obstacle or reaching the wire.

Good to know: Robot lawnmowers don’t collect grass clippings but return them to the ground. This is because they cut the grass frequently before it can grow tall.

They may also integrate a rain sensor so that when it starts to rain they automatically stop. Most lawnmowers are designed to be waterproof, but mowing wet grass isn’t usually a good idea.

The most advanced robot lawnmowers may create a virtual map of your garden and have a systematic rather than random approach to mowing.

Manufacturers often provide a mobile app to enable users to program, schedule and control the mower. Connectivity is possible through Bluethooth, Wi-Fi, or GPS.

This means that your robotic lawnmower can operate at specific hours without requiring to be manually turned on or off each time.

Important: The autonomy and mowing area of a robot lawnmower depends on its battery and cutting width. Most models need at least an hour or two to fully charge.

Today, robot lawnmowers are being used to maintain large areas of grass in commercial or public settings, so top-rated models can handle a private lawn or large backyard without issues.

Robot Lawnmower Benefits

So what exactly are the benefits of a robot lawnmower compared to a gas, electric lawn mower, or pushmower?

Saves You Time

Robot lawnmowers can cut the grass while you’re at work, inside the house relaxing, or having a barbecue by the pool. Once you set them up, they don’t require your physical presence.

You may miss the physical exercise you get with a conventional mower, but you sure save a lot of time!

Increases Safety

Another notable benefit of this type of lawnmower is that it minimizing the risk of accidents resulting from flying debris, chords, or fires.

And since you don’t have to follow it around the lawn, your toes are perfectly safe, too!

Better Results

The first automatic lawn mowers may not have been the most efficient, but today, robot lawnmowing technologies have developed substantially.

The best robot mowers on the market now can navigate uneven terrain, adjust their program automatically, and recommend optimal mowing schedules.

This means healthier grass and a better lawn.

Requires Less Storage Space

Robot lawnmowers tend to have a smaller design so they won’t take much space. You can fit them into different garden storage solutions.

It’s More Convenient

Mowing the grass regularly isn’t everyone’s idea of fun. Maybe you like having a nice lawn but don’t always have the energy or willpower to mow it.

A robot lawnmower offers a convenient alternative to getting the job done with no serious effort on your part. It frees you from a regular chore so you can use that time in more fun ways.

It’s Environmentally Friendly

The most efficient robot lawnmowers may not be solar-powered just yet, but they are electric. That makes them a more environmentally conscious choice compared to gas-powered lawnmowers.

Makes Maintenance Easy

Automated lawnmowers require only blade changes and regular cleaning. You don’t have to worry about oil changes or air filters.

Protects Your Health

Grass allergies can be unpleasant–and quite unavoidable with most types of lawnmowers. But not with robot lawnmowers, which do the work for you when you’re not around.

In the end, the benefits you get depend on the model you choose. Some models are more advanced than others and provide better value for your money.

Which brings us to our selection of the best popular robot lawn mowers available now.
