Best Robot Lawn Mowers for 2021 Mowing Made Easy

There's no avoiding it...It's time to mow the lawn again, and there are a million things you would rather do. It can be done without the time and effort! Here are the 7 best robot lawn mowers on the market according to my thorough research.

1. Worx WR140 Landroid M 20V
2. Echo TM-1000
3. Ambrogio 4.0 Elite
4. Husqvarna Automower 315
5. Robomow RS630
6. MowRo RM24
7. Honda Miimo HRM520

When I was younger I did a lot of gardening and golf course maintenance jobs so naturally I appreciate a well maintained lawn.

My reason for switching to a robot lawn mower is that I simply do not have the time to mow the lawn myself anymore. I noticed my lawn has started to look much healthier and greener. This is due to how frequently the robot lawn mower cuts the grass and how those fine clippings fertilize the lawn. In this case, machine definitely beats man!

Robot lawn mowers come in many different shapes, sizes, and a range of prices. Some are quite expensive, so if you are shopping around it is important to take a few key points into account, the first of these being your lawn size. You don’t need to buy a mower that can maintain 3 acres if your lawn is only 0.3 acres.

Your second consideration should be its weight as you will be the one that has to flip it over for maintenance and lift it when storing it away for the winter. Thirdly don’t pay for features you won’t use, a basic model is all you need if your lawn is small and has a level surface.

Robot Lawn Mower Pros

Investing in a robot lawn mower can save you time and money on maintaining your lawn. Another benefit is that they eliminate air pollution. Gas-powered lawn mowers cause up to 5% of total air pollution in the US. Robot lawn mowers are also substantially quieter than gas-powered lawn mowers, your working-from-home neighbor will thank you for that!

Lastly, you’ll need less fertilizer and likely less water for a healthier lawn. Most robot lawn mowers can be programmed to mow as often as you see fit, typically they mow every day or every second day. This frequency of mowing puts much less stress on the grass and keeps it at a consistent length. Safety is always a priority, and all of the mowers on the list have safety sensors as standard. If your robot mower bumps into an object it will stop, turn, and keep on mowing in a different direction.

Robot Lawn Mower Cons

Even though they do the mowing for you, the first cut after winter will need to be done with a push mower or ride on. Robot lawn mowers do what their name states, and nothing more. If your yard needs cleaning you’ll still need to do that yourself, be it leaves, toys, or a mess your dog made. Also, the edges of your lawn will still need manual trimming to tidy it up from time to time. Some models require good cellphone coverage to operate properly, and software issues can occur that might need customer service or technicians to resolve them. It is also important to note that these robots can occasionally get stuck and you will need to correct them.

1. Worx WR140 Landroid M 20V

This robot lawn mower serves all the needs of the standard and entry-level customer. The Worx Landroid is affordable and has received great reviews from both experts and customers alike. It is best suited for moderately sloped and flat lawns of small to average size. One of its best features is the mobile app control and programming. Instead of built-in batteries, it uses Worx 20V batteries that work with all Worx tools. It also does a cut around the perimeter of your lawn weekly to keep the edges tidier.

Stats

  • Weight: 21 lbs
  • Max mowing area: 0.3 acres
  • Cutting height: 2-3.5 inches
  • Max slope angle: 20°
  • Cutting width: 7 inches
  • 3 Year Warranty

Pros

  • Lightweight
  • Mobile app control and programming
  • Affordable

Cons

  • Not great for uneven lawns

2. Echo TM-1000

This robot mower is the hardest working mower on the list and will maintain up to 3 acres. If you have an exceptionally large yard, you are either spending hours upon hours mowing yourself or paying someone else a small fortune to maintain it for you. The TM-1000 is definitely pricey and is designed to carry out commercial scale maintenance, where it will likely result in savings on labor time and cost. This mower does not take days off, even when it’s raining! Echo is a renowned manufacturer of quality chainsaws and trimmers and you can be quite sure this product will follow suit. The TM 2000 (big brother of the TM 1000) already maintains in excess of 1200 soccer fields across Europe.

Stats

  • Weight: 105.6 lbs
  • Max mowing area: 3 acres
  • Mowing height: 0.8 – 3.9 inches
  • Max slope: 17.5°
  • Cutting width: 24.9 inches
  • 1 year Warranty

Pros

  • Very Powerful
  • Highly durable (All weather mowing)
  • Can mow for many hours on a full charge
  • Mobile app control and programming

Cons

  • Has to be professionally installed
  • Very Heavy to lift for maintenance and storage
  • Expensive
  • Low max slope rating

3. Ambrogio 4.0 Elite

While the Ambrogio 4.0 Elite comes with a large price tag and only double the mowing area of the Worx Landroid, I believe it is justified considering the extra features it offers. This robot lawn mower comes with an option of two battery upgrades that can double its mowing area to cover 1.2 acres! Its double-wheel design also provides for more traction and its pivoted platform does a better job of mowing uneven lawns and steep slopes.

The extra premium battery upgrade option has inductive charging which means it charges by simply brushing up against its docking station, meaning the contact points which normally get dirty do not need to make clean contact. This is very useful in dusty and humid climates. Another intelligent design feature is the grated blade safety cover. This allows rainwater to wash the blades and helps to clear out debris that builds up during mowing. However, the most impressive feature for me is the 6 year warranty (2 year standard + 4 year extension). Most competitors offer a warranty of 3 years or less.

Stats

  • Weight: 35 pounds
  • Max mowing area: 0.6 acres (standard battery) – 1.2 acres (upgraded battery)
  • Cutting height: 0.8 – 2.5 inches
  • Max slope: 35°
  • Cutting width: 9.8 inches
  • Up to 6 Years Warranty!

Pros

  • Confidence inspiring warranty
  • Designed to handle uneven and sloped lawns
  • Mobile app control and programming
  • Appealing design
  • Good on slopes

Cons

  • Expensive

4. Husqvarna Automower 315

The Automower 315 made by Husqvarna – a brand name with a strong reputation for quality and has been a top player in the robot lawn mower arena from the start. More suited for smaller lawns of up to 0.3 acres, the strongest argument in favor of this small mower is its control compatibility across devices. It can be controlled and programmed using a mobile app, it is also compatible with Amazon Alexa and Google Home for basic voice instructions such as stop, start and park. If you want a truly smart home compatible robot lawn mower, look no further.

Stats

  • Weight: 18.1 lbs.
  • Cutting height: 0.79 – 2.36 inches
  • Max mowing area: 0.3 acres
  • Max slope: 20°
  • Cutting width: 7.8 inches
  • Warranty: 3 years if dealer-serviced, 2 years if not

Pros

  • User friendly
  • Compatible across smart devices
  • Lightweight
  • Mobile app control and programming

Cons

  • Costly considering max mowing area

5. Robomow RS630

If you have a slightly larger, more complex yard and are looking for a middle ground between the Worx Landroid and Ambrogio 4.0 Elite, this could be the perfect option for you. This model by the well-established Robomow can be programmed to mow your lawn in zones. It offers a mobile app to control and program it easily, while it also has Amazon Alexa compatibility. A built-in rain sensor will guide it back to its docking station if there is a downpour and it will resume when conditions improve. This mower packs a powerful punch and is durable with its weatherproof design.

Stats

  • Weight 86.8 lbs
  • Cutting height: 1.05 – 3.25 inches

The RM24 comes pre-programmed to mow your lawn every two days, meaning you don’t need to customize anything. Customer reviews across platforms are very positive about this model and you can be confident that you are getting a great quality mower for a fantastic price.

7. Honda Miimo HRM520

Honda never disappoints when it comes to quality and innovation and their Miimo mower is no exception. Unlike other robot lawn mowers that cut in a random pattern, the Miimo cuts a repeating V pattern which is much more efficient for long, narrow lawns. It can be programmed to cut according to the season, more in Spring and less near the end of Summer. The only drawback is that it has no Wi-Fi or Bluetooth connectivity and it does not come with a mobile app. Programming is done using the controls on the mower. On the plus side, with a 45° max slope rating, this mower could basically climb a mountain!

Stats

  • Weight: 26 lbs.
  • Mowing height: 0.8 – 2.4 inches
  • Max mowing area: 0.37 acres
  • Max slope: 45°
  • Cutting width: 8.6 inches
  • 2 Year Warranty

Pros

  • Excellent, reliable performance
  • Lightweight
  • Great slope mowing ability

Cons

  • No rain sensor
  • No Bluetooth or Wi-Fi control
  • No mobile app
  • Must be professionally installed

DIY installation is possible with many of the models listed above, it might take a few hours, but the bonus is you only have to do it once. Depending on the layout and complexity of your lawn, it may be necessary to get professional installers to do it for you. Be aware that professional installation may cost more if the setup is very complex.

Maintenance

IMPORTANT: ENSURE THE MASTER SWITCH IS TURNED OFF BEFORE ANY CLEANING OR MAINTENANCE WORK IS CARRIED OUT ON THE MACHINE.

Robot lawn mowers require much less servicing and maintenance than conventional lawn mowers. This is due to them having fewer moving parts. Basic maintenance you can do yourself is to regularly clean it by carefully turning it upside down and removing grass from the underside and blades with a coarse brush and damp cloth. You may also need to change the blades and batteries when needed, or get it done professionally. It is also advisable to store your robot lawn mower away where it will be safe and dry during the winter months.
