Perception change: landscapers implement robotic lawn mowers into everyday use

Robotic lawn mowers have been making an impression in the green industry for a quarter of a century, and over the last few years, they’ve truly hit their stride in popularity among professional landscapers.

Last year, Total Landscape Care talked with experts about what robotic mowers could mean for the green industry long term, as well as what myths needed to be debunked about these machines.

This year, experts are taking a look at what improvements these machines have undergone, how perceptions have changed regarding robotic mowers and where they believe this niche could be heading.

What’s changed?


Last year, many landscaping professionals were still warming up to the idea of using robotic mowers and even more were convinced that the robots would end up taking their jobs. Thankfully, the opposite has proven true, as many companies are now finding these machines serve as a good supplement to the nationwide labor shortage.

Steven Uljua, product manager for robotics with Husqvarna, says he has definitely seen a change in the adoption of robotic mowers over the past year. Last year, Uljua says the adoption rate among landscapers was fairly low; now, he says it ranges from medium to medium-high, and it’s only getting better.

“This is just another tool for them to help them stay profitable,” says Uljua. “My wish would be to that the landscapers would think about it and understand that we’re not trying to put you out of work. This doesn’t do hedges, it doesn’t fertilize, it doesn’t do all the things that we still need you to do. What it will do is make you become a better landscaper because you’ll have all this time to do the things you wish you could do.”

Brian Manke, product manager for robotic mowers with STIHL, says they are already seeing a lot more interest in robotics from their customers.

“The hesitation in the industry is still there, but you can see the ball slowly moving towards more people being interested and probably more people that will start testing this concept,” says Manke.

Manke says the mowers are now being used by the individual purchaser and homeowner, as well as by commercial users wanting to create a robotic mower fleet for their company. With popularity for these machines growing, Manke says more landscaping companies have even created robotic mower branches.

In the beginning, Manke says the most common question he heard was, “Does it really work?” Now, he finds that more serious questions about pricing, maintenance, installation costs and more are asked instead.

Kris Kiser, president of the Outdoor Power Equipment Institute (OPEI), notes that he’s seen an influx of commercial landscapers breaking into this market. He adds that more services have been developed where landscapers own the equipment and install it for the customer to provide direct service for them without the need to deal with dealers or financing.

According to data OPEI collected, Kiser says robotic mower sales are increasing, and in January, OPEI and the American National Standards Institute (ANSI) published a set of robotic mower standards that Kiser says will help further expand the marketplace for this product.

Logan Fahey, CEO of Robin Autopilot, says it’s true that a robotic mower won’t be the perfect fit for every yard and every customer, and when selling the idea to professional landscapers, he stresses that it’s important to make sure you are selling to a consumer that’s going to be successful with the technology.

“In 2020 and especially in 2021, we’re starting to see that the manufacturers are making adjustments to the mowers for the US market, which is a huge step forward,” says Fahey. “All those things are progressing and we were an early adopter, which is a risk I think that’s certainly paying off.”


Experts agree that most of the upgrades that have taken place since last year have been geared software and reliability, although, Uljua says Husqvarna did introduce an all-wheel-drive option that will take a 35-degree slope to ensure landscapers don’t have to risk their own safety tending to steeper slopes on a zero-turn.

Up until the all-wheel-drive mower, Uljua says all robotic mowers had to go to a dealer to plug it in for a software update, and depending on the dealer, you could be charged for that service. With this new mower, Uljua says it’s their first machine with firmware over the air (FOTA), and updates can now be sent out with no trip to the dealer.

Along with being able to push out updates, Uljua says FOTA also allows landscapers to clear a non-safety related fault from a distance without having to report to a property and type in a PIN code.

“That’s been a big push for us in the commercial market to eliminate just driving out to a house to start a mower back up again,” says Uljua.

Fahey says the challenge every year is to make these mowers even smarter, and Kiser notes that there have been numerous updates in the abilities of these machines in just a year’s time, such as the battery life, topography recognition, driveability and cutting ability.

“There are a lot of manufacturers in this space and coming into this space, so you’re going to see more product offerings,” says Kiser. “As they use them, they better understand them, and they take that information and incorporate it into future designs.”

Last year, Manke says one of the biggest roadblocks that kept people from fully adopting robotic mowers was not having connected mower models, but he adds that they are getting closer to having a connected version of the iMow available.

Manke says they’ve been working on the app and the back-end systems over the past year, and STIHL continues to look for more enhancements and revisions that are geared toward fleet users. Manke says the goal is to give users better tools, better visibility and better organizations of the iMow that’s geared toward large scale installations.

For STIHL, Manke says robotic mowers are a key pillar that they believe will be important to their future, and for their connected model, they will be using an LTEM connection, which will be good for the life of the machine. Manke says it will also have a web portal that will allow users to see full visibility of the iMow through a web page, as well as on the app.

In the commercial setting, Manke says the web feature will come in handy when managing multiple machines.

Check back tomorrow for part two, where we’ll see some of the benefits and drawbacks of these machines, as well as where these experts believe the robotic mower industry is heading.

Advantages of a STIHL iMow Robotic Lawn Mower

Intelligence – A Mower That Thinks iMow has a fully automated mowing plan tailored to every yard. For example, if it’s raining, the rain sensor tells iMow not to mow and to catch up on the lost mowing time later in the week.

Maximum Flexibility During Charging and Mowing To cover a large area in a short time, iMow can recharge quicker and adjust its speed to suit the mowing conditions. For example, if it’s taking the night off, it charges itself slowly, thus extending battery life.

Mows Evenly Across All Areas iMow can be programmed to mow a variety of yard layouts in the front or back yard. It cuts several times a week so your lawn never has that “needs to be mowed” look.

A Beautiful Lawn in Every Way iMow has an edge mowing option that results in a clean cut along the edges of your mowing area. You can also plan how your iMow returns to the docking station by choosing between following the perimeter wire or making the journey to the docking station using a random pattern. The docking station is powered by an outdoor wall outlet.

Greener, Healthier Lawn iMow is a mulching mower that finely shreds the grass clippings, returning them to the lawn as an effective fertilizer. This nourishes for a thick and healthy lawn.

Safety and Security iMow is equipped with a variety of sensors. If someone attempts to lift or tip the iMow the mowing blade is designed to stop. The user sets a defined PIN in the iMow menu, which cannot be changed, even if the battery is removed or the unit is reset.

Quiet iMow mows so quietly, neighbours will hardly notice it’s there. Plus, iMow emits no exhaust emissions while working.

Allergy Relief iMow doesn’t kick up dust and dirt like a tradional mower, which helps provide relief for people with allergies.

Dealer Installation Right from the start, a STIHL iMow Dealer will provide personal advice and professional installation.

Competition closes in

The RMI 632 iMow robotic lawn mower can handle large areas of up to 4,000m² with great ease. There’s no need to worry about disposing of grass clippings – the clever mulching blade shreds all clippings finely, then drops them back on to the lawn to act as an incredible fertiliser, aiding thicker and healthier growth. The powerful battery ensures a perfect cut in just a few hours. When the battery begins to run low, it will take itself back to the docking station to charge. Depending on how much of the grass is left to cut, the robotic lawn mower reduces energy consumption by intelligently deciding whether a quick or slower charge is needed.

Bright LCD display – The control panel is integrated into the housing of the STIHL iMow robotic mower and features a large LCD display. It provides a intuitive way of recording all settings, as well as a way of viewing all functions and performance data of the automatic lawn mower. The high-contrast, bright display is easy to read even in sunlight.

Movable hood – The movable hood with sensors protects the STIHL iMow robotic mower from weather and obstacles. If the iMow robotic mower comes up against an obstacle during automatic mowing, the integrated sensors detect contact with the object and changes direction.

All-round protection – The STIHL iMow robotic mower is equipped with various sensors. As soon as someone attempts to pick it up while mowing, it stops. In addition, the automatic lawn mower can be protected with a PIN code. If it is configured so that it can only be operated by entering a PIN, it is protected from unauthorised use.

Standard equipment – Standard equipment for the STIHL iMow robotic mower includes the machine, the docking station, four pegs for securing the docking station to the ground as well as an iMow ruler as an aid for laying the perimeter wire. An installation kit is also required to install the iMow robotic mower.

Docking station – The docking station is included as standard equipment for the STIHL iMow robotic mower. It is both the robotic mower’s home and where it charges its battery. At the same time, it is the starting point for every mowing operation. When driving, the automatic lawn mower is guided by the signal transmitted by the perimeter wire at the edge of the lawn. This signal is fed via the docking station. If it rains or the battery runs down during mowing, the iMow robotic mower independently returns to the docking station and recharges its battery. Thanks to its intelligent charging system, the iMow decides independently whether an express charge is necessary due to another imminent mowing operation or whether the battery should be charged more gently in normal mode. The docking station can be placed within or outside the lawn area.

Mulching mowing deck – The sturdy iMow mulching blade ensures a precise cutting pattern even on higher grass growth. Its rotational direction changes automatically every time the blade stops. This means that the blades of the automatic lawn mower wear evenly. The blade can be changed without the need for tools.

Offset drive home – By default, the iMow robotic mower travels back home to the docking station along the perimeter wire. If required, and depending on the condition of the edge of the mowing area, the iMow can also travel to its docking station with an alternating offset to the perimeter wire.

Removable control panel – The control panel with integrated and bright display is used on all STIHL iMow robotic mowers for easy setup, manual control and fast display of machine information. The high-contrast display means the control panel can also be used in sunlight. The panel is flush-mounted in the housing of the automatic lawn mower and can also be removed for convenient access.

App control – The iMow app transforms a STIHL iMow robotic mower into a standalone Smart garden system. The intuitive app menu can be accessed via smartphone or tablet, which means that many mowing settings can be made not only directly on the machine but also while on the move. The free iMow app offers a real-time overview of main functions and performance data. Using the interactive mowing plan, time Windows can be defined for each day during which the iMow robotic mower works flexibly and independently and charges its battery. Thanks to the integrated rain sensor and receipt of online weather forecasts, the automatic lawn mower only mows in suitable weather conditions. Using GPS localisation, the current location can also be viewed and a desired zone can be defined as the preferred mowing location at a specific time.

iMow robotic mower drive – The STIHL iMow robotic mowers feature a drive that enables them to mow hilly terrain with consistently high quality. The RMI 422 can handle gradients of up to 35%, while the other automatic lawn mowers from the RMI 4 series can cope with a gradient of up to 40%.

Adaptive slope speed – Using the adaptive slope speed function, the STIHL iMow robotic mower adapts its speed on uneven terrain. The integrated tilt sensor constantly analyses the position of the automatic lawn mower and adapts its speed accordingly.

Dynamic mowing plan – Using the STIHL iMow robotic mower interactive mowing plan, individual time Windows during which the machine can be in operation can be defined for each day. Within these active times, the automatic lawn mower automatically determines the best times to mow for an optimum result. If it has to interrupt mowing because of rain, it automatically catches up later within the specified time window. The dynamic mowing plan can be called up and amended via the control panel.

Wheels with traction pattern – The smooth-running wheels with traction pattern ensure that the STIHL iMow robotic mower moves with precision. Especially on hilly lawns with a slight gradient of up to 45% and denser grass growth. The treaded wheels of the automatic lawn mower are self-cleaning.
