How does a robotic lawn mower work?
Robot lawn mowers are not just for large yards. They can be used on any size yard, and they’re perfect if you have a tricky slope to navigate or lots of obstacles in your way.
Every robotic lawnmower is different, but most work by being programmed with the day and time that you want them to come out and do their job.
When it’s time for the machine to start cutting your grass, it will go about doing its duties automatically using sensors as well as blades that spin 360 degrees at high speed.
Some people worry about safety when these machines are around–after all, there are sharp spinning blades involved! The good news is that robot lawn movers use infrared technology, which prevents them from colliding with objects in the yard.
How to choose a robot lawn mower?
A robot lawnmower will run a little differently than one you push or ride along with, so it’s important to think about your own specific needs and preferences. Here are some of the most common questions people have when they’re trying to decide which robotic mowers might be best for them:
Do I want my machine to cut grass in different patterns? Some machines offer blades that rotate in multiple directions (360 degrees) while others can only go forward–each has its pros and cons. Ask yourself what kind of pattern cuts you like!
How often do I need my yard done? If you don’t mind cutting the grass every day, then an electric device is probably better for you because they require less maintenance. If you can only make it out to the yard every couple of days or so, then a gas-powered machine may be better for your needs.
How much space do I have? This one is pretty obvious–the more room you need to be mowed at once, the bigger and heavier of a machine you’ll need.
How much money do I want to spend?
This is the ultimate question of deciding what machine will best suit your needs. If you’re on a tight budget, then an electric device or gas-powered push mower may be for you.
However, if you have more funds to invest in this area of lawn care and would like the ability to create patterns with blades that rotate 360 degrees–then maybe one of these machines is right for you!
What to Look Before Buying Robot Lawn Mower For Slopes?
- Size Of lawn And Battery Size
One of the most important considerations when purchasing a robotic lawn mower is how big your yard is.
Many of the lighter-duty models come with batteries that are designed to last for short periods, typically starting at models that can cover up to 400 square meters. Heavier duty units usually extend coverage to larger lawns, up to 3000 or more square meters.
Larger lawns require larger batteries, more powerful motors, large cutting blades, and advanced software. As a result of this, they are considerably more expensive than smaller-sized mowers.
- Gradient Of Slope, the Robotic Mower Can Manage
The more hilly the terrain, the longer it takes for a robotic lawn mower to cover all of your yard.
You can choose from a variety of models with different handling capabilities and operational ranges. Before you buy one, carefully consider its ability to manage steep slopes and other challenges that come with large yards.
- How to Calculate the slope Of your steep hill or large lawn?
The slope of your garden is calculated by taking the height difference in meters and dividing it by how far the distance was travelled. This would be written as: Slope = (height change, m) / (distance traveled, m). For example, if you have a one-meter gradient over five meters of travel, then your slope will equal 0.20 or 20%.
Generally, robotic lawn mowers can manage slopes of about 30 degrees. For a steeper slope, you need models that have the steepest gradient.
- The blade size
The blade size determines how much grass your machine can cut per minute. Generally, a blade range of between 30 and 45 cm is sufficient for most yards.
Full and heavy-duty blades will make the lawn movers more efficient but they are not always a requirement.
- Power System
Most robotic lawn mowers are either battery-operated or electric, and both have their advantages. An electric robot lawn mower typically has a long-lasting rechargeable battery, while the batteries on a cordless model can be swapped out when they run low.
Battery power is advantageous because it doesn’t require any wiring to install, whereas an all-electric system will need to be plugged in, but you’ll never have to worry about running out of juice at the wrong time.
Features Of Robot Lawn Mowers That Ensure Good Slope And Hill Performance
. Front-wheel drive – in general, front-wheel-driven blades do a better job on inclines than rear-wheel drives because they have more traction and can push up steeper grades with less effort.
· Tires designed to climb steep slopes – tires made specifically for climbing slopes will provide better traction when ascending or descending inclines
· Powered by battery rather than electricity – batteries last longer between charges which means you’ll spend less time charging it while still maintaining good hill performance. Plus, there’s no need to install wiring, so installation is much simpler.
- Wheel Design
A front-wheel-drive will be the best choice for most users because it’s less likely to slip and slide during use or be more difficult when going up hills.
Rear-wheel drives are sometimes recommended for maneuverability around tight corners, but they may not perform well in hilly areas due to reduced traction while climbing steep slopes.
A slope climb tractor tire is designed specifically for hill work and provides excellent grip even on wet grass since its tread pattern digs into the ground better than a regular lawn mower tire would.
- Rain And Moisture Detection Systems
– Rain sensors detect the presence of water and signal when it reaches a certain threshold.
– Moisture sensors can be installed in the soil to measure how wet or dry the surface is, which helps determine if irrigation needs are required for specific plants.
- Low Centre Of Gravity
One of the key factors in determining a robot mower’s maneuverability is its centre of gravity.
If you have an incline with slopes on both sides, your lawnmower will not be able to cut the grass evenly and effectively when it only has one wheel that can navigate up or down the hillside.
Problems When Installing Your Robot Lawn Mower – How to overcome?
Install a ridge that has a gradual incline for the robot to navigate.
Slope correction can be done by adding an additional set of wheels or using guides in order to create an easier path up and down your slope.
If you have a steep slope, it would be impossible for any robot mower to cope with; consider planting an area or adding a retaining wall.
This way, the height difference between the two sides of your incline will decrease and create an easier path for the lawnmower.
In addition, this can also create space in order to plant specific plants – such as trees or flowers- which require different levels of sunlight exposure depending on their type.
Always keep in mind that there are some safety hazards when it comes to the use of lawnmower robots.
For example, if a charging robot is not supervised at all times and encounters an obstruction on one side or the other, it may topple over as they cannot stop themselves from sliding down the slope due to their momentum.
Even though this possibility might seem unlikely for most users, you should always be aware of your surroundings before starting up your mowing device and ensure you have cleared away any objects which could interfere with its motion.
The controls for robotic lawn mowers differ from one model to the other, and you should research before buying what type of control system your potential purchase would be compatible with.
Typically, a remote or app can act as a controlling device which allows users to start up their machine remotely or programming it in advance if they so choose. A wireless signal will tell the robot when it needs to move on to its next position. Other models might have self-adjusting rotary blades that automatically turn off and stop moving after they sense an obstruction nearby such as trees or rocks.
Another alternative is boundary wire technology (perimeter wire), where wires are laid out all across the terrain (usually over plants), producing signals telling the robot exactly where not to go.
Some models are programmed to not start up when they detect an obstruction nearby. However, the more advanced robotic mowers can be accessed remotely and started by any person with a Wi-Fi signal or cell phone connection.
Most of these functions have been put in place because some people worry that someone might try to steal their lawn robot. The idea is that even if you’re away from home for long periods of time, your machine will protect your yard at all costs!
Furthermore, most models come with a security system built in like keyless entry where you only need to enter your personal code on the remote control panel before initiating operation, which keeps unwanted visitors out so no one other than yourself can access it while still being able to activate it remotely.
Obstacles are also another big concern to a lot of people. They don’t want their lawn mower robot running into any obstacles in its path while it’s out on the job and ruining its blades or worse yet, getting tangled up!
For this reason, some models come with obstacle detection sensors, so when they sense something is blocking them from continuing on their pre-programmed route they will automatically go around.
Some robotic mowers might not be able to handle hills all that well because the programming isn’t as sophisticated, but most bots can climb inclines at an angle of 15-20 degrees at full power without issues.
This robotic lawn mower can handle a yard of up to 1.25 acres.

The key thing to think about when getting a robot lawn mower is how large is your yard. If you have an exceptionally small or flat one that won’t take too long to cut, then a smaller model might be in order.
But if it’s on the larger side, especially if there are hills and obstacles involved, then go with something big as we have recommended.
