If you want a perfect lawn without the effort, a STIHL iMOW® robotic mower is what you need. By mowing little and often, your lawn will always look freshly cut with an iMOW®. It cuts the grass clippings finely and drops them back into the ground to act as a fertiliser so your lawn will look lusher over time too, without even lifting a finger!

iMOW® is powered by Lithium-Ion battery technology, so there are no emissions or fumes to worry about.

The adaptive charging system aligns the charge time with the cutting schedule, so choosing a slow and gentle charge more often will help you to save energy.

Powerful cordless technology means iMOW® is able to cut the most demanding of lawns.

The RMI 6 series are capable of mowing gradients of up to 45%. That’s a 45cm change in height over a distance of 100cm.


iMOW® mows your lawn automatically and according to your garden's needs. The built in sensors safely react to moving and static objects within the garden, which in turn moves iMOW® to cut in another direction.

iMOW® will also remember how much lawn has been cut and how much is left of the mowing plan. If it has a large area left to mow and the battery is running low, it will charge itself faster. And when it is done working for the day, it charges at a slower and more economical rate which helps to prolong battery life and save energy.


iMOW® uses a double sharpened mulching blade to mow the grass and ensure a precise cutting pattern. The rotational direction of the blade changes automatically every time the blade stops to ensure even blade wear and a longer service life.

Safety measures have been put in place to stop the blade automatically as soon as someone tries to lift the iMOW®.

Whilst mowing, the iMOW® cuts and finely shreds the grass clippings which fall back onto the lawn, acting as an effective natural fertiliser (known as mulching).

Lush Lawn

The iMOW® robotic mower mows and cares for your lawn at the same time: it shreds the grass clippings finely, which fall back onto the lawn acting as a effective fertiliser (known as mulching).

Not only does this provide vital nourishment to help grow a thick and healthy lawn, it also means there are no grass clippings to collect and dispose of.

Quick & Smart

iMOW® is one of the fastest robotic mowers on the market, giving you more time to enjoy your freshly cut lawn.

In order to maintain that both the cut and the quality is of the highest standard, iMOW® adjusts it's working speed according to the gradient of the terrain and the length of the grass to leave lawn with a precise finish.


Come rain or shine iMOW® keeps mowing until the job is done.

Adaptive slope speed technology means iMOW® can mow inclines of up to 45% with ease.

The robotic mower adjusts its speed to suit the mowing conditions, moving slower over long, thick grass or on hilly terrain.


Wherever you are, the iMOW® app gives you full control of your mower via your mobile device.

The iMOW® app connects to any iMOW® C or PC model and the intuitively designed interface enables you to configure the mowing plan, pause or start new mowing operations, read status messages and performance data from the comfort of your home or office – all in real time.

You can download the iMOW® app from the App Store and Google play.

You can buy a STIHL iMOW® from us at Balgownie Ltd. We can offer you an initial consultation, install it for you and maintain it afterwards. If you want to find out more about how to choose the right iMOW® in the first place, just take a look at the video for guidance.

The mowing plan is created automatically or manually depending on your lawns needs. Whether you prefer for iMOW® to work when you are at home or when you are sleeping, you can program it to your preference. iMOW® not only cuts automatically according to plan, but also adds in a buffer zone to make up for any cutting time it may have missed as a result of battery charging or rain (if the rain sensor is activated).

For obstacles such as flower beds, ornamental shrubs and other objects, a loop can be easily installed which acts as an exclusion zone. When iMOW® encounters any unplanned objects such as barbeques or deck chairs, the sensors under the hood automatically reverse the mower and move it off in another direction.

The iMOW® robotic mower is equipped with a variety of sensors. As soon as someone attempts to lift iMOW®, it stops. If iMOW® hits a static object, it simply moves into another direction. iMOW® can also be set so that it can only be operated following entry of a pre-defined PIN code.

The mowing zone is defined with a perimeter wire which transmits an interference-free signal. This means that the signal does not compete with other signals.

All iMOW® models are equipped with an alarm that is activated when the machine is lifted. iMOW® can be set so it can only be operated following the entry of a PIN code. On the C model of iMOW®, you can also choose to receive an email or text message in the event that your machine is stolen and then locate it with your mobile device using the iMOW® app.

Yes. The 6 series models of iMOW® have a removable control panel that allows you to steer iMOW® as well as manually changing the settings. The LCD is always clear on iMOW® to read, regardless of weather conditions.

The wide range of robotic mowers are ideal for mowing lawns of all sizes, up to 5000 m². If your lawn has many nooks and crannies, these can be taken into account and an optimal solution will be found for your lawn layout.

iMOW® is a mulching mower and therefore requires no grass collector. By cutting the grass into very small pieces, the trimmings disappear back into the lawn and provide valuable nutrients to the soil. This eventually leads to a lush and healthy lawn.

Yes. iMOW® is extremely quiet and is capable of cutting at night.

The soft edges located at ground level (such as a low patio or walkway) can be included within the installation. For hard edges (such as walls and elevated patios), iMOW® can be installed so that it can run as close to the edge as possible.

Yes. Provided they are connected within the same wiring loop, a second, separate grassy area may also be mowed if it has its own docking area.
