How Does a Robotic Mower Work?
How do robotic lawn mowers work?
How do robotic lawn mowers work?
Robotic lawn mowers use advanced navigation technology to map your lawn and mow it automatically, without the need for boundary wires.
Once your lawn is mapped and the mowing schedule is set, the mower takes care of the rest - mowing regularly, navigating around obstacles, moving between lawn areas, and returning to its charging station when needed.
Because it cuts little and often, the fine grass clippings are left behind to naturally break down and feed the lawn, helping maintain a consistently tidy, healthy finish.
How does the robotic mower know where to mow?
How does the robotic mower know where to mow?
Wire-free robot mowers know where to mow by using advanced positioning and navigation technology to work within a virtual map of your lawn.
During setup, we create the mowing area in the app, including boundaries, no-go zones, and any different lawn sections. The mower then follows that map while using onboard technology such as satellite positioning, vision, cameras, or LiDAR (depending on the model) to stay on course and navigate accurately around your property.
This allows the mower to mow in a controlled, systematic way while staying within the areas it has been assigned.

Are robot mowers safe around families and pets?
Are robot mowers safe around families and pets?
Yes. Modern robotic lawn mowers are designed with multiple safety features to help them operate safely around everyday family life.
Depending on the model, this can include cameras, sensors, object avoidance and advanced vision systems such as VisionFence, which help the mower detect and navigate around people, pets, toys and other objects on the lawn.
The blades are also positioned underneath the mower, and built-in safety systems can stop the cutting system if the mower is lifted, tipped or detects an obstruction.
Are robotic mowers environmentally friendly?
Are robotic mowers environmentally friendly?
Robotic lawn mowers are a more environmentally friendly alternative to traditional petrol-powered mowing.
They run on rechargeable batteries, produce no direct exhaust emissions while mowing, and operate much more quietly than petrol mowers.
Because they mow little and often, the fine grass clippings are left on the lawn to naturally break down and return nutrients to the soil, reducing the need to collect and dispose of grass clippings.
Are robotic mowers noisy?
Are robotic mowers noisy?
No. Robotic lawn mowers are much quieter than traditional petrol lawn mowers.
Our quietest models operate from around 60 dB, allowing them to quietly maintain your lawn in the background without causing much disruption around the home.
Their low noise levels also give you greater flexibility when scheduling mowing, including early mornings or at night, depending on what suits your property and household.
Can a robotic mower handle Kikuyu grass?
Can a robotic mower handle Kikuyu grass?
Yes. Robotic lawn mowers can handle Kikuyu grass very well, provided the right mower is matched to the property.
Kikuyu is a fast-growing, dense grass, so regular mowing actually suits it really well. A robot mower keeps on top of the growth by cutting little and often, helping maintain a neat, consistent finish rather than letting the grass get long between cuts.
We have Kikuyu here at MowBot HQ and the lawns look like a golf course! Many of our customers also have Kikuyu, and the key is mowing frequently during the high-growth seasons and keeping the lawn short so the thatch doesn’t get away on you. In summer, we often have our own robot mowers running every day.
For thicker Kikuyu, larger lawns or sloped properties, we’ll recommend a mower with the right power and traction for the job.
Can a robotic mower cut long grass?
Can a robotic mower cut long grass?
Robotic lawn mowers are designed to maintain your lawn by mowing little and often, rather than tackling very long or overgrown grass.
If the lawn has been left to grow out, we usually recommend giving it an initial mow first and then letting the robot take over from there. Once set up, regular mowing helps keep the grass short, tidy and under control without it getting away on you again.
Some models can handle taller and thicker grass better than others, so we’ll recommend the right mower based on your lawn conditions and property.
How often should the robot mower cut the grass?
How often should the robot mower cut the grass?
Robot mowers work best when they mow regularly, cutting a small amount of grass each time rather than letting the lawn grow long between mows.
How often your mower should run will depend on your lawn, grass type and the time of year. During high-growth periods, some lawns may benefit from mowing every day, while slower-growing lawns may only need a few mowing sessions each week.
Because the mower is only taking a small amount off each time, regular mowing helps maintain a consistently tidy finish and keeps the lawn under control throughout the season.
Can robotic mowers handle complex lawns?
Can robotic mowers handle complex lawns?
Yes. Modern robotic lawn mowers can handle much more than just a simple, flat square lawn.
Depending on the model, they can navigate multiple lawn areas, narrow passages, slopes, trees, garden beds, retaining walls and other obstacles around the property.
The key is matching the right mower and navigation technology to the lawn. For more complex properties, we’ll look at things like layout, access between areas, slopes, tree coverage and signal conditions before recommending the best option.
Irregular Mowing vs. Systematic Mowing
Irregular Mowing vs. Systematic Mowing
Irregular mowing means the mower travels around the lawn in a more random pattern, changing direction as it reaches boundaries or obstacles.
Systematic mowing is much more organised. The mower follows planned mowing lines across the lawn, working methodically through each area rather than moving around randomly.
Modern wire-free robot mowers use systematic mowing to cover the lawn efficiently, reduce unnecessary overlap and create a cleaner, more consistent finish.
Can a robotic mower handle steep slopes?
Can a robotic mower handle steep slopes?
Yes. Many modern robotic lawn mowers are designed to handle sloped and uneven properties, but the capability varies between models.
Our most capable models can handle slopes of up to 40°, while others are better suited to gentler terrain.
For steeper properties, we’ll look at the gradient, ground conditions, traction and overall layout before recommending the right mower for the job.
How long does the battery last on a robotic mower?
How long does the battery last on a robotic mower?
Battery runtime varies depending on the mower model, lawn size, terrain and mowing conditions.
Robot mowers are designed to manage this automatically. When the battery gets low, the mower returns to its charging station, recharges, and then continues mowing if there is still work to do.
The lithium-ion batteries are also designed for long-term use, but like any rechargeable battery, capacity will gradually reduce over time and the battery may eventually need replacing.
What happens if it rains while the robotic mower is working?
What happens if it rains while the robotic mower is working?
Robotic lawn mowers are designed to live outdoors and keep working through changing weather conditions.
Day or night, rain or shine, your robotic mower works for you, keeping on top of the lawn so you don’t have to.
Depending on the model and your preferences, rain settings can also be adjusted through the app, giving you control over whether your mower continues mowing or waits for better conditions.
Do robotic mowers require a lot of maintenance?
Do robotic mowers require a lot of maintenance?
Robotic lawn mowers are relatively low-maintenance, with no ongoing fuel costs and only a small amount of regular upkeep needed to keep them performing at their best.
We recommend giving the mower a quick clean around once a month and replacing the blades approximately every 6–8 weeks, depending on how often it’s running and the conditions it’s working in.
Like anything, the better you look after it, the better it will perform.
We also recommend regular servicing, particularly for machines working hard throughout the year. This gives our service team the chance to check wear items, moving parts, seals, software and the overall condition of the mower.
Do robotic mowers need to be serviced?
Do robotic mowers need to be serviced?
Yes. Like any piece of outdoor equipment, robotic lawn mowers benefit from regular servicing to keep them running reliably and performing at their best.
We recommend having your mower serviced once a year. During a service, our team checks the mower over, cleans it thoroughly, inspects wear items and moving parts, checks seals and software, and replaces any parts that need attention.
Regular servicing can help catch wear and tear early, extend the life of your mower and keep it working reliably season after season.
At MowBot, we also provide ongoing service and support, so you’ve got a team to call if your mower ever needs attention.
What is the lifespan of a robotic mower?
What is the lifespan of a robotic mower?
A well-maintained robotic lawn mower can last for many years, especially when it is regularly serviced and replacement parts are available when needed.
At MowBot, we only supply brands that we know we can support long term. Both Husqvarna and Segway continue producing replacement parts for 10 years after the last production of a model, which means parts can still be available well beyond the time that particular mower stops being sold.
With regular maintenance, servicing and the ability to replace worn components over time, a quality robotic lawn mower can provide reliable mowing for many years.
Robot Mower Tech Terms Glossary
RTK, GNSS, EFLS, GPS, EPOS... what...?!?
We've put together a little list of terms to help you understand what they all mean.
What does GNSS mean?
What does GNSS mean?
GNSS stands for Global Navigation Satellite System. It's a generic term for satellite navigation systems that provide geolocation and time information to a receiver anywhere on or near the Earth's surface. The most well-known GNSS is the Global Positioning System (GPS), but there are other systems like GLONASS (Russia), Galileo (Europe), and BeiDou (China). These systems use a network of satellites to provide precise positioning and navigation information.

EFLS (Exact Fusion Locating System) is a unique high-precision localization technology used by Navimow. It combines satellite positioning with data from multiple sensors, such as the vision camera, gyroscopes, accelerometers, magnetic compasses, and odometers, to enhance positioning accuracy and fault tolerance.
What are the benefits of EFLS 2.0?
What are the benefits of EFLS 2.0?
EFLS 2.0 integrates camera sensor data to reduce errors caused by poor GPS signals. During mapping, the lawnmower uses its camera to capture key environmental features like houses and trees, improving navigation accuracy.
What is SLAM?
What is SLAM?
SLAM, or Simultaneous Localization and Mapping, is a technology used by robotic mowers to navigate and map your lawn. It allows the mower to create a real-time map of its environment while simultaneously tracking its own position on that map. This helps the mower efficiently plan its mowing route, avoid obstacles, and cover the entire lawn systematically, even in complex or changing environments.
What is LiDAR?
What is LiDAR?
LiDAR, or Light Detection and Ranging, is a technology used in some robotic mowers to create a detailed map of your lawn. By emitting laser pulses and measuring their reflection off objects, LiDAR helps the mower accurately detect obstacles, navigate efficiently, and ensure precise coverage while avoiding collisions.
A LiDAR-based SLAM system uses a laser sensor to generate a 3D map of its environment.
