Robotic Mowers. By STIHL.

STIHL iMOW® robot lawn mowers have a robust, double-sharpened mulching blade for a guaranteed precise cut. The mulching blade means a STIHL iMOW® robotic lawn mower doesn’t just cut the grass; it also shreds the clippings into tiny pieces and distributes them across the lawn as mulch, which soon decomposes and supplies your soil with the nutrients it needs to support healthy grass. This highly effective natural fertilisation method means that regular mowing results in a greener, lusher lawn.

The rotational direction of the blade is automatically changed with each use, ensuring even wear and a longer service life. STIHL have of course not overlooked safety considerations: if a STIHL iMOW® robot lawn mower is lifted up, the blade stops automatically. A manual stop button offers additional security.

We believe that a STIHL iMOW® should make your life simpler and more relaxed. With that in mind, we have designed it to be especially easy to use, and programming is child’s play thanks to the intuitive user interface – no expert knowledge needed. Our C models can even be controlled using the iMOW® app and a smart home system, after initial setup.

STIHL iMOW® robot lawn mowers operate at a maximum volume of just 60 dB (A), so your time in the garden won’t be disturbed.

An integrated rain sensor enables STIHL iMOW® robotic lawn mowers to pause mowing processes during wet weather. This function protects your lawn, as mowing grass on wet soil can damage its roots. Once it is dry again, the STIHL iMOW® will automatically resume mowing.

STIHL iMOW® models feature central cut height adjustment which enables you to quickly set your mower to the desired grass length between 20 and 60 millimetres (8 settings). The adjustment is also very precise, as you can read the cutter bar setting from a scale at any time.

The reliable iMOW® robot lawn mower can mow even challenging lawns. Its impact sensors enable it to detect fixed obstacles on the lawn, which it then circumvents independently. You can also define the positions of trees, bushes or flowerbeds using the restricted areas function.

The STIHL iMOW® can work on gradients of up to 45% with ease, adjusting its mowing speed as it goes. So hilly areas are no problem for the robotic lawn mower.

Each of our STIHL iMOW® robot lawn mowers is powered by a lithium-ion battery and has a built-in smart charging system. This allows the iMOW® to charge its battery particularly quickly when it needs to swiftly resume an ongoing mowing process; at times when there is no mowing planned, the battery is automatically recharged using the gentler, slow charging process.

The iMOW® automatically creates a mowing plan which is tailored to the size of your mowing area. You can adjust this pre-defined mowing plan at any time to suit your needs and change the active times of the robot mower. The iMOW® is also flexible: if a mowing process is interrupted, e.g. because it is raining, the mower will resume this process during its next active period.

These features protect your iMOW® against theft and interference. The GPS location feature on our C models offers an additional layer of security.

STIHL iMOW® robot lawn mowers include smartwatch compatibility too, for Watch OS, Wear OS and Tizen smartwatches. You can use the STIHL iMOW® smartwatch app to start mowing and edging processes, send the STIHL iMOW® to its charging station, access statistics and easily view the active times.

All STIHL iMOW® C and PC models can be controlled using Alexa, Apple Home Kit and Google Home. This means that you can use voice control to start and stop mowing processes or check the current status of your robot mower. In order to activate smart home skills for your STIHL robotic lawn mower, you will first need to connect it to your iMOW® account.

All STIHL iMOW® C and PC models can be integrated into the innogy SmartHome system. This adds extra smart features to the mower’s standard controls, by means of connection with other parts of the SmartHome system. For example, if there are children who may be running around the garden, SmartHome can detect when the garden door has been opened and automatically order the robot mower to return to its charging station.

The iMOW® robot mower is suitable for small, medium and large lawns up to 5,000 m² in size, depending on the model and condition. If your lawn is very irregular in shape, your dealer will be pleased to take a look and find the right solution for you.

iMOW® machines are mulching mowers and do not need a grass collection box. During mowing, the mulching blade chops the cut grass into small pieces; these pieces are then distributed on the ground, where they break down to become an organic fertiliser and help your grass grow even thicker and greener.

Low, navigable edges (e.g. terraces or paths at ground level) are accounted for by the perimeter wire in such a way that the iMOW® robot mower cuts the edge of the grass cleanly and thoroughly. For hard edges (e.g. walls or raised terraces), the iMOW® robotic lawn mower is installed in such a way that it travels as closely as possible along the edge.

Yes, if the areas are connected with the perimeter wire or if you have a second docking station. In the latter case, you need to transfer the mower to the other part each time it needs mowing.

Contact an authorised STIHL dealer near you for a personal consultation. Once you have chosen the iMOW® robot lawn mower which is best for you, your dealer can draw a plan of the area to be mown. Your dealer will also be pleased to help you lay the perimeter wire and select the ideal position for the docking station, and can then assist you with programming your iMOW® robotic lawn mower and getting it ready for use.

Your iMOW® robot mower will automatically create the appropriate mowing plan to ensure ideal grass condition. You may, of course, adjust this mowing plan as you wish and, for example, specify the times at which the iMOW® robotic lawn mower should mow the lawn. The iMOW® robot mower will then cut the grass automatically based on your individual mowing plan.

Bushes, flower beds, trees and other fixed elements in your garden can be cordoned off using the perimeter wire. If the iMOW® robot mower detects an unexpected obstacle, e.g. garden furniture, it will use the sensors under its hood to identify the best direction to travel around the obstacle.

Your garden may be home not only to pets, but also to wildlife such as hedgehogs. You can find out if you have any wild visitors to your garden by installing a wildlife camera. The camera will record your garden from different perspectives, even at night, and let you know whether you need to take any precautions. You can significantly reduce the risk of injuring hedgehogs by ensuring that your robot mower is only active during the day: hedgehogs are nocturnal animals and are therefore especially threatened by evening or night mowing processes. The operating instructions for your iMOW® contain further instructions on how to use your mower correctly and how to protect wildlife.

Please bear in mind that hedgehogs are a protected species and it is illegal to catch them and remove them from their natural habitats. The only exception is if you are assisting a sick hedgehog, but in these cases, the animal must be released into the wild again as soon as it has recovered.

Every iMOW® robotic mower is equipped with a variety of sensors. The device will stop as soon as anyone touches it or tries to lift it up. You can also set up your iMOW® robot mower so that it can only be operated on entry of a PIN. The manual stop button offers additional safety.

Yes. You can do this via the screen on RMI 422 models and using the removable control console for the RMI 632. The special LCD screen is easy to read in all weather conditions.

All iMOW® robot mowers are equipped with an alarm which is triggered if the mower is lifted up. Our iMOW® robot mowers can also be set up so that they can only be operated if a PIN is entered. For C models, there is an additional option that allows you to receive an email or push notification if the iMOW® robotic lawn mower is removed from the mowing area – and with the iMOW® app, you’ll always know where it is.
