How to Buy the Best Robotic Lawn Mowers

The best robotic lawn mower for your garden will take the effort out of keeping the lawn neat and tidy. A robot grass cutter requires little to no work once it is set up and is a pleasure to use. 

There are several things to consider before investing in the best automatic lawn mower:

Size of Lawn Area

This is one of the most important considerations when selecting a self-mowing lawn mower. You need to invest in one that can comfortably cover the size of your lawn area. 

If you are looking for the best robotic mower for 1 acre, a robot mower for 2 acres, or even the best robot lawn mower for 5 acres, you might have to look at the more industrial models on the market. 

Cutting Width

The cutting width will determine how much grass is cut with every pass so the size of your garden will determine the ideal cutting width. Too small and will take forever to cut a large lawn, too large and it will not be accurate and agile in a smaller garden. 

Battery Life

The longer the battery life the more work the auto lawn mower can do between charges. Good battery life will make it more efficient. 

Automatic Recharge

The great thing about automatic lawn mower robot models is they sense when the battery is running low and return to the docking station to recharge. You don’t have to lift a finger. 

Single and Multi-Zones

If you have a simple patch of lawn this is not an issue but for more complex gardens with various areas of grass, you will need one that has a multi-zone feature. This allows it to automatically move from zone to zone without any effort from you. 

Cutting Height

One needs to adjust the cutting height according to the type of grass you have, your preference, the seasons, and weather conditions. Some mowers have a very limited range of height settings while others give you more options.

Noise

A mowing robot is naturally quieter than a petrol lawn mower and even a corded electric mower. Due to the way they operate they even make less noise than most battery-powered mowers. This is a benefit as it will not disturb your household or your neighbours. 

Mulching

Mulching means cutting the grass blades into very small pieces. These can remain on the lawn and break down naturally. This process is basically like free fertiliser and will enrich the soil. The result, apart from not having to rake up grass, is a healthy verdant lawn. 

Communication Technolgy

Some lawn robot designs are fairly basic and are either programmed manually or with a simple display panel. The more sophisticated robotic cordless lawn mower models use a range of communication protocols such as WiFi and Bluetooth. This gives you a true remote control lawn mower and greater convenience. Apps allow you to control the mower from your mobile device making a smart mower. 

Ease of Set Up 

The hardest part about using a robot grass mower is the initial setup. This only needs to be done once and is generally quite simple. It involves setting up the docking station and laying the boundary wires. Most models come with everything you need. Once set up, you can relax and let the grass-cutting robot do all the hard work. 

Frequently Asked Questions

Are robot lawn mowers any good?

Yes, the modern ones are very good. Some early models were problematic but the technology, design, and batteries have improved dramatically over recent years. There are many good robot lawn mowers on the market. 

How do robot lawn mowers work?

They are battery-operated and (most) return automatically to a charging dock that is plugged into an electrical outlet. During the installation process, guide wires are laid at the edges of the lawn to tell it where to go and where not to go. You can program various features depending on your lawn and your preference. 

Robot lawn mower – where does the grass go?

Since automatic mowers cut more often they take off less grass than a conventional mower so grass clippings should not be an issue. If it has not worked for a while you might need to rake up the clippings and dispose of them. Some mowers have a mulching feature that leaves fine clipping on the lawn. These break down and feed nutrients into the soil. 

How big a yard can a robot lawn mower do?

This comes down to the cutting width and the power of the battery. You get models that cut small gardens of a few 100m² up to over 1800m². For much larger gardens you will need an advanced robot lawn mower specifically designed for large areas. 

How to prevent theft of robot lawn mower

Many mowers come with technology to protect them. These include alarms/alerts, lift sensors, PIN codes, and a GPS locator feature similar to those found on a mobile phone. You can also get an installation lock or a time lock device.

What happens if you put a robot mower on a lawn that’s too big? 

The majority of mowers cut in a random fashion. The battery, even the best ones, has a limited life. If the lawn is too big for the robot mower it will never be able to get to all areas of the lawn. You will find the area closer to the charging dock to be cut fairly well while the outlying areas cut very little if at all. 

How to program a robotic lawn mower

This largely depends on the technology the mower uses and what features you want to use. Some are pretty much plug-and-play once you have installed the guide wires and docking station. A Bluetooth app is one of the most common ways to program a robotic lawn mower. These apps are generally user-friendly and guide you through the process. Others use LEDs or a display panel.

How much is a robotic lawn mower?

They range in price from under £400 to north of £2000. It depends on the brand, size, technology, and features. 

Conclusion

If you wanted to know more about the benefits of robot lawn mowers you should now have everything you need to know. We also gave you some good tips on 8 of the best robot mowers on the market.
