Robot Lawn Mower Buying Guide


A considerably new, but costly smart-techno product, these robot lawnmowers are the typical siblings of the robot vacuum cleaner. Designed to tackle the various sizes of lawns, the kinds of grass and terrains, these small-sized robots roam freely in your lawns and give them a new, picture-perfect look every time.

Now, mowing the lawn is not a chore you have to jot down over and over on your to-do list; these bots can do all the work in extreme hot weathers as well as during the cold nights.

So, whether you have a small front and back lawn, or a large garden, there are various options available for you to select the best one for your home.

When deciding upon the right robot mower, the following essential points will help you remain focused on your needs and analyze the minimum requirements every bot has to fulfill.

Lawn Area

You first need to analyze your own lawn and your requirements from the basic mowing robot. Once you know your lawn size, and that means the area covered with grass only that needs trimming, it will help you gauge the features of each robot individually.

A large-sized mower can handle a larger area with more ease. A smaller one may have to go back and recharge in case the battery runs out in the midst of its operation. However, their smart features help them remember where they stopped, and they resume their function once the battery is charged from that point onwards.

If your lawn is inclined or has a number of bushes that make it a little harder to maneuver through for the lawn bot, look for one with a greater capacity. This will be easier and more compatible with your lawn.


How well the automatic mower is able to undertake instructions from you is the main quality feature a particularly good bot should have. This can help you set up weekly or even daily schedules for it to operate with ease.

Some of the models are typically programmed at the base, however, other advanced models can be instructed via Bluetooth and smartphones through an app. The app also gives other vital details of your robot mower including the remaining battery life, the charging status, etc.


The wattage the mower runs on is a good estimate of the post-purchase cost it will bear.

Another important consideration is battery life or how frequently the unit has to be charged before use. You have various chargers and batteries available openly in the market for these bots. You may even buy a solar powered light charger for saving up on your electricity bills, a newer battery which charges quickly in case the unit allows replacement or charge it through its dock station that comes with it as part of the package.

Typically, there are two types of charging options:

Charging through dock or base station: There is a proper base station for the mower to go to once the battery runs low, or when they finish off a particular lawn job.

Charging manually: These types have to be taken to a power source and plugged in to charge.


All bots consider safety as a prime feature of their manufacturing. With mowing, the main injuries typically result from:

  • Objects were thrown out from under the cutter blades, like rocks, sticks, etc.
  • From slipping from behind the wheels while pushing the lawnmower forward. These robotic mowers have minimized all possibilities of injuries resulting from such incidences.

They work around their defined boundary by keeping within limits of the perimeter wire around their area of operation.

The best part is, in case it senses any serious or dangerous situation, it automatically shuts down immediately.

A few additional safety features include:

  • There should always be sufficient space between the blade and the chassis for a safer cutting mechanism.
  • It should be equipped with sensors that shut it down completely in case it tilts to a dangerous inclination angle or is picked up from the ground.
  • There should always be a STOP button in clear view for anyone to access and push in case of an emergency.

Remember the Zones

Some of these models do not wander into different lots. For example, if your front and backyard are not connected, the lawn bot will not go straight to the backside and start operating.

There are models with the ‘multi-zone’ capacity for this purpose, which help you instruct it to treat both the areas as a separate and distinct zone. So that the entire area can be covered easily.

Start/Shut Down Function

Usually, these bots have a manual start function but can also be programmed for say, a week, where they start and shut down their operation as programmed.

Security Features

Since these robots require substantial financing, one may worry about them being safe while wandering out in the open. However, you can rest assured, most of the models come equipped with safety features which include an anti-theft alarm system as well as a user PIN for increased protection against being stolen or used by anyone else.

Now some of the models also have a GPS-tracking system to enable further security.


Although these robots are extremely low maintenance, you may have to clean grass or rubble particles that can stick to their blades or the inside of the frame. This has to be done occasionally but thoroughly and more frequently in case, your lawn is damp while being trimmed.

Use During Winters

It is best to avoid the usage of these robots during winters, especially during the snow. It could lead to corrosion and damage to the blades as they run through the hardened icy blades of grass.

However, before keeping away your unit during the winters, always dry it completely, clean and store it in a dry place. Also, store the charging dock inside for safer storage.

Ease of Use

Another important consideration is the usage, that is, how easily programmable the mower is for use. You should always read the manual to understand the display and the functionality of the model and decide on the one which is easy to give instructions to and navigate through the lawn.


The ease of repairs, or after sales service is also a good thing to be considered. Since this involves relatively new technology, you may need a certain assistance or repair work with the product. So, always keep a check on good dealers, preferably in the same localities as you to get help instantly when faced with such situations.


The sellers may provide set-up and installation packages, or the dealers in your area can help you set them up.

However, they are so simple to start, that you can do it on your own! One lawn bot takes about 2 hours to a maximum of 5 hours to completely get ready.

Use During Extreme Summers

These automatic mowers are strong enough to tolerate and function in extreme weather of up to 113 degrees Fahrenheit. However, the battery capacity may run low during extremely hot weather, but again that is not an issue, as the mower will work on a smaller area and go for recharge and return back to work, till the whole operation is completed.

Blade Life

This depends on the usage of the robot. If your lawn is more rugged and the grass is rougher than normal, it may go up to 1-2 months. However, the blades are fairly simple to replace and can be replaced by an amateur within minutes.


A key constituent of your choice of automatic mowers. You need to look for the one which works well, instead of just trying to find a cheaper one.

A robot mower with a better manufacturing and sturdier body and blades is likely to cause less trouble and last for long as compared to a cheaper option. It is a one-time investment for many, so think before you pay.

These robots are further friendly for the neighborhood due to their features of:

Noiseless Operation

A great feature of these robots is that they function without much sound. This way they can go out in the open even at night, or when all the neighborhood is quiet without disturbing the peace and silence of the area.

Environmental Friendly

With no emissions or noise, these lawn bots run on the batteries and are not just proficient in their work, but also energy efficient.

The latest features provide further ease of controlling these little gnawers, like smartphone accessibility, and programmable scheduled instructions. These robotic mowers give the ultimate convenience to anyone with a lawn or garden to employ them for free for a perfect trim every time.

Are These Robot Mowers Safe?

Are These Robot Mowers Safe?

These lawn bots are programmed to mow your lawn unsupervised and are indeed the safest for use. The only known injuries resulting from the manual mowers so far include slipping from behind the mower and from thrown objects, so, instead of operating these mowers if you stay aside and let them work on their own, it reduces the chances of any accidents from taking place.

Moreover, they often come with built-in safety smart sensors to enable them to sense any changes in their surroundings such lift-ups from the ground, inclines, human touch, etc. and they just cut-off their motors in case of such situations.

Even if you have pets at home, most of them will stay away from this moving beast, but even if the most curious ones try to get in its way, they will not be harmed and will ultimately learn to ignore it and let it go about on its own.

The robot is also designed to stay within the perimeters of your lawn. If due to some rare instance it does cross its boundaries, it shuts off by itself immediately.

As compared to the traditional mowers, these robots are the safest to operate. With the manual lawn mowers, frequent accidents like loss of a limb, toes or worse have often taken place and are indeed a hazard and very unsafe to be kept out in the open too. These robots do have the sharpest and dangerous blades under the body, but these are still much safer and tend no harm to anyone.

They also have smart sensors to prevent any collisions from taking place and also turn and change their course instantly in case of any pets or children, etc. in the way.

How Well Can These Mowers Do the Job?

These robots get the job done the best way possible. They are designed to cover the entire lawn and can even access the remotest areas of the lawn by themselves. Your lawn can also be trimmed on a daily, bi-weekly or weekly basis, as you desire. It leaves behind a fresh, greener and cleaner lawn, always looking like it has just had a fresh cut.

It works even better than you or anyone you employ to smooth out the lawn, and gnaws its way through the entire area, trimming every strand of grass neatly and with an expert’s touch. Easy to use and program, you can order this robot to trim out your lawn every day!

Capable of working even at night, silently, it works without causing any disturbances in the neighborhood. The smart technology even lets it judge the growth of the grass and decide its cutting schedule as per the requirement. Here is a more detailed answer of the question.

Can It Sense Obstacles?

Any obstructions or obstacles like trees, a ceramic fountain in the center of your garden, cats, and dogs loitering at their leisure, are not harmed or even touched by the smart sensors built-in its design.

If any object comes within contact of this mowing robot, it may feel a slight bump, but without any damage and instantly the mower will change its course. Keep in mind, generally, all objects of 4 inches or higher are treated as an obstacle, however, smaller objects may be cut or damaged by the blades.

If the obstacles include softer areas like the swimming pool or flower beds, they have to be put out of its perimeters while setting the perimeter wire.

Most lawn bots can handle slopes if the incline is not that high that it can put the mower at risk of being toppled over. Typically a 25-28 degree incline is considered safe.


Selecting the right robot lawn mower for your yard can be a very baffling experience. With technology still developing and the latest features still being incorporated in these mini-robots, a further reduction in prices is expected to take place as these pods further entrench the markets.

So, employ a safe and environment-friendly robot today and save the sweat, time and get the perfectly trimmed lawn that the entire neighborhood desires!
