What are robot lawn mowers exactly?

Robot lawn mowers are electronic devices with a battery powered motor that cut grass autonomously. Most commonly, they operate within a predetermined area bounded by low voltage cables that must be installed before use. They also usually have collision sensors to avoid hitting objects, people or animals in their path.

What types of robot lawn mowers are currently available on the market?

The main distinction between the two main types of robot lawn mowers is based on whether or not they require the use of a perimeter cable to delimit the work area. If a unit does not require this installation process, they will be easier to setup. However, these days more than 90% of current models of robot lawn mowers do use this type of system.

How do robot lawn mowers work?

Robot lawn mowers are fully automated and work within a predetermined zone. This is made possible by the use of a series of low voltage wires that delimit the working area. These cables are completely safe and can usually be buried, so that they are not accidentally tripped over.

Do I need to be careful using a robot lawn mower?

The majority of robot lawn mowers are waterproof, which means they can cut grass in the rain without any issues. However, they do require some basic maintenance tasks. Periodically check to make sure there are no obstructions or dirt accumulated under the unit. If your mower begins to cut less evenly or efficiently, it is probably time to replace the blades.

Shopping Criteria

When choosing a new robot lawn mower, it is important that you take several important factors into account. In order to find the option that best suits your needs from the wide-range of models currently available on the market, just keep the following criteria in mind when making your purchase.

The Size of Your Lawn

The characteristics of your lawn where you are a going to be using your new robot lawn mower, is the most important factor to keep in mind when making your purchase. It is important to consider not only the overall size, but also whether the terrain is flat or has steep slopes. The robot's capacity is usually calculated for flat and uniform terrain.

If your lawn is quite large or has more challenging terrain, you need to find a unit with a greater capacity. In the case of terrain with steep slopes, you will need a more powerful robot that has good traction. Some of the latest models are capable of working on slopes with a gradient of up to 50%.

Cutting Options

Most robot lawn mowers can cut grass at several different levels. The first specification you should check is the maximum cutting height. If the grass on your lawn is above that value, you will need to mow it with a traditional lawnmower first. It is also important that you never cut your grass too short, as it can leave brown or bare-looking patches on your lawn.

Some of the more high-end robot lawn mowers have a feature that crushes and spreads out the blades of cut grass. This not only allows smoother operation, but it is also a great way to turn cut grass into an eco-friendly natural fertilizer for the soil. Or else you can easily clean up the cut grass using a leaf blower.

Blades

Most blades used by robot lawn mowers are fairly inexpensive and are not too complicated to replace. However, you should still check what type of blades the unit uses and how often they need to be replaced. Double-edged blades offer cleaner cutting and a lower energy consumption. Other commonly used types of blades are tempered and thin blades.

If you have children or pets that are often playing out on the grass of your lawn, you need to find a robot with retractable blades or that has a protective cover over the blade. Another option is a model that has a safety system that will automatically shut the unit off, if it detects any movement or it is accidentally overturned.

Battery Life

This is a an important factor if you have a very large garden. Some robots can function continuously for up to two hours, which should be enough for the average user. It is also a good idea to check how long the battery takes to fully recharge.

Control and Connectivity

The vast majority of robot lawn mowers are fully programmable, and most of them can also be controlled using a remote. If you choose a robot with WiFi or Bluetooth connectivity, you will be able to control it using your mobile phone. Another great feature is an anti-theft system, allowing you to leave your robot running while you are indoors.

The most common types of anti-theft systems utilize a PIN for activation or an alarm. Rain detectors will stop the robot from cutting as soon as it starts to rain, and reactivate again after it has stopped. Even though many models of robot lawn mowers can work in rainy conditions, it's actually not the best idea as wet grass cuts more unevenly.

Noise Level

Choosing a robot with the lowest possible noise levels will give you and your neighbors more piece of mind every time you want to mow your lawn. This is particularly true if you want the robot to operate at night, when even the smallest amount of noise is much more annoying. However, generally speaking a robot that is quieter will be less powerful, so you need to find a balance between low noise levels and adequate power for your requirements.

Noise level is measured in decibels (dB). The average noise level of a road is around 90 dB, and sound of the wind in the trees is roughly 25 dB. Anything under 60 dB is low enough to not be overly annoying, but there are some great units that operate much more quietly, although they are less powerful. However, if you only need the robot to cut a small area that is fairly flat, one of these quieter models is definitely the best option.

Summary

Owning a robot lawn mower will free you from the annoying task of mowing your lawn, and give you more time to spend doing what you love. Some of the best models currently available on the market are even capable of operating in challenging conditions such as over steep terrain or in the rain. They also feature safety and security systems to prevent accidents and theft.

It is not surprising that these gadgets are becoming increasingly popular with consumers. The first thing you should take into account when choosing a robot lawn mower is the dimensions and configuration of your lawn where it will be operated. Other factors such as battery life and control options are also important to consider.
