STIHL iMOW® 4.0 Robotic Lawnmower – Up to 1,000 m² Coverage (GB Model)

IA020111431 – Compact, Quiet & Smart Lawn Care Solution

The iMOW® 4 is part of the latest generation of iMOW® robotic mowers from STIHL. Designed for home gardens, these robotic mowers mow your lawn automatically so you don’t have to, giving you a beautiful green lawn, without even lifting a finger. Capable of cutting lawns of up to 1,000 m2 and gradients of up to 40%, the iMOW® is powered by a high-performance lithium-ion battery for efficient and continuous work over long working periods.

The iMOW® is controlled using the MY iMOW® app which controls all of the functions for the robotic mower, such as sending it out to mow, returning it to the dock, changing the mowing plan, adjusting the cutting height or checking the current status of the iMOW®. The robotic mower connects to the MY iMOW® app via your home WiFi network if this reaches your garden or via a Bluetooth connection when you are close to the machine.

The iMOW® is installed by laying or burying a thin wire around the outer edge of your lawn and around obstacles in your garden, such as shrubs, trees, flower beds or water features. Then, a second wire in the centre of your lawn helps the iMOW® to travel home to charge. If the iMOW® comes across objects in the mowing area then it’s sensors will activate, causing it to slow down, softly bump into it and then go off into another direction. You can install you iMOW® yourself via the MY iMOW® app, which provides guided instructions on how to complete the install. You can also follow our playlist on how to install the iMOW® too! If installing this way, you will need the appropriate installation kit (sold separately) for your garden size in order to install the iMOW®. For complex gardens with multiple mowing plans, you can request for your local STIHL Approved Dealer to install the iMOW®. To do so, please get in touch with your local STIHL Approved Dealer directly.

The iMOW® is fitted with 3 free-swinging, extra-sharp blades which provide a clean cut lawn every time. These blades rotate each time they stop, meaning the last for longer before needing to be replaced. The iMOW® is a mulching mower. Mulching is the process of cutting the grass into small clippings which are then dropped back into the lawn, acting as a natural and nutrient-rich fertiliser. Plus you have the added bonus of not having to empty a grass catcher box again! Because the iMOW® cuts the grass little and often, the clippings decompose quickly – leaving no trace of them, apart from a well-nourished, lush, green lawn.

You can build a dynamic mowing plan for your iMOW® which is tailored to your needs and program it to mow at a time that is convenient for you. However, if you do want to send the iMOW® out to mow when you are relaxing in your garden then you can – it’s so quiet that you wouldn’t even notice it when it’s out mowing! Rain sensors on the iMOW® detect when it rains so you can choose whether to let the iMOW® continue to work in the rain or make up the mowing time when it dries up. Thanks to the intuitive software of the iMOW®, you don’t have to worry about charging it either – when the iMOW® finishes it’s mowing plan it finds its way back to it’s weather-proof docking station and charges itself efficiently, ready for the next time it goes out to cut.

If you want to check the status of the iMOW® or can’t access the MY iMOW® app, you can press the info button on the control panel at the top of the iMOW® which will talk to you and tell you when the next mowing session is. Using these buttons you can send the iMOW® home, out to mow or lock the mower without going onto the app.

Please be aware that the iMOW® robotic mower is not a toy. Children and small animals must be kept away from the mowing area when it is out to mow. You must also make sure the mowing area is clear of small objects such as footballs and toys. For further safety information, please read the instruction manual.

The iMOW® will receive security updates for at least 24 months after purchase.
