How to Choose the Best Robot Lawn Mower?

You can dream about a lawn and execute it soon, but the problem arises when it asks for maintenance because you got no time. Thanks to the latest development, there is a wide range of robotic mowers that can cut the lawn grasses without many inputs.

However, all of them are not equal. To find the best robotic lawnmower, you need to consider some of the factors that we will discuss now. But before that, you should be aware of some basics about their working.

How Does a Robot Lawnmower Work?

All the robotic mowers follow a mapping system to navigate. You need to set an area using boundary wire and you can also peg it around obstacles. When a robotic mower reaches its boundary wire it changes the direction.

The machine uses a battery-powered motor for movement, blades to cut the grasses and some sensors that help it to be on the course. It includes an AC compatible base or docking station that is responsible to charge the battery as well as provide electronic signals to the mower. Onboard sensors on the mower catch these signals to navigate and return to its base when the battery is low.

Talking about the battery, most of the robot mower uses a Lithium-ion rechargeable cell with a runtime ranging anywhere between 30 minutes to 4 hours. The battery backup depends largely on the price, weight and the mowing conditions.

Buttons to program the mower are generally present on the control panel. The common settings that you can access from this panel are the power button, mowing timer, changing the cutting height, and configuring the zones. Most of the autonomous mowers run quietly. The average sound output among the mower is between 55 dB to 65 dB.

However, not all of them operate at low sound levels, some of the mowers cross the sound level of 75 dB. Such machines are not suitable for late-night or early morning usage.

Size of The Lawn and Deck Size

What is the size of your garden? It’s the first factor that you need to figure out because robotic mowers differ in terms of coverage area.

Moreover, a machine that can mow a significant land also comes with a powerful battery pack that can take it along all the grass beds and decorations. As you can see, the coverage area depends upon the make and model. So, make sure you choose something that has the calibre to mow your land.

Deck size or the cutting width is the area a mower can cut at one time while at work. Some of the robotic mowers use single blade while several others use a spinning disc with multiple blades attached with it.

If you own a small land, then try a mower with 15 or 16 cm blade. Mowers with 17 cm or bigger blades are better for large areas. All the mowers cut the grasses into tiny pieces and leave them on the ground that fertilizes the grasses. Moreover, you don’t have to worry about the disposal of these clippings.

Price range: Autonomous mowers are not affordable when compared to other versions. However, entry-level models are available at comparatively lower prices when compared to high ends options. No matter what is the price tag, you need to make sure that the machine can cover your lawn. There is no point spending on a tool that cannot maintain your garden properly.

That also because it lacks power: In the section of robotic mower reviews, we have separately mentioned the coverage area so that you can easily choose one of them. The machines are available between a price range of $600 to $3500. So, choose something that can cover your lawn as well as available within the budget. The initial cost will rise if you choose to contact professionals for the installation. So, if you can follow the instruction, try to peg the boundary wire yourself.

Functions: Once you filter the models according to the cutting width, lawn size and price range, now it’s time to check the features. If you own a large lawn, then try to find a mower that can work according to the configured zones. Such a feature helps the machine to concentrate on a particular area for better output. Moreover, when you create the zones the mower simply travels to the same region that also extends the battery life.

Robotic mowers can perform when it’s raining. Not all of them, but most of these machines can. However, mowing wet grasses might not be fruitful. Wet soil will easily stick to the blades and deck, which will only leave its surface once you clean them using a hose. What is the purpose of an autonomous mower if you are spending a lot of time maintaining it?

Moreover, its wheels will slip and the cuttings might not be accurate and attractive. These are the reasons why you should look for a mower with a rain sensor. Such a mower will return to its docking station when it starts raining heavily.

Ability to move over inclines paths is another function you should consider, especially if you have a lawn with lots of hills and slopes. Most of these tools can handle slopes up to 15 degrees, but some of them can mover 35 degrees as well.

Cutting height: Robotic mowers can cut the lawn grasses at multiple heights according to your preferences. Some of them give you the option on the control panel via a dial. Several other models come with a compatible app, wherein you can use a smartphone to change the settings. Choose a model that suits the lawn and its grass type.

It might be not necessary for this section. However, we want to let you know that all the robotic lawnmowers use GPS that helps it to know the cutting areas and the regions already covered. Apart from the GPS, these tools use Wi-Fi as well as Bluetooth to connect with your smartphone.

So, choose a machine that comes with a smartphone app, so that you can control from virtually anywhere. Some of the models also offer voice control that you can execute using an assistant like Alexa or Google Home.

Safety features: A robotic mower should stop its blade movement once it finds no contact with the ground. It’s the first safety feature that a mower must-have for your protection.

Moreover, it should also raise an alarm once the mower leaves the ground. It might be a thief who is trying to take control of your possession. There is a function wherein you need to enter a pin code to activate the mower again once it leaves the ground.

Installation: Installing a robotic mower is not difficult, but might be a cumbersome task in case of big lawns. All the autonomous mowers come with clear instructions that you can follow and finish the setup.

You can also check the installation videos available on the manufacturer’s website. So, manage a time slot of one hour and try to peg the boundary wire yourself. The period might change according to the shape and size of your lawn.

If you don’t want to follow the installation steps or you don’t have the time to do it, then you can always contact professional services to install a robotic lawnmower. Be ready to spend some more money, but take a quote before you call them home.

Once the mower is ready, you can use it according to the requirements. Clean its blades once you notice soil and change its blades according to the instructions. You can use a brush or garden hose to clean the mower.

Recharge time and battery backup: Check the robotic mower reviews and you will understand that some of the models take some extra time to recharge while several others take a small break to be back online. So, look for a model that can work for a longer period. So that you don’t have to face any downtime.
