iMOW 4.0 Robot mower

iMOW® 4: Automatic lawn care for your garden

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.

Control via MY iMOW® app

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.

Simple installation with guided setup

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, its sensors will activate, causing it to slow down, softly bump into it, and then go off in another direction. You can install your iMOW® yourself via the MY iMOW® app, which provides guided instructions on how to complete the install. If installing this way, you will need the appropriate installation kit (sold separately) for your garden size. For complex gardens with multiple mowing plans, we offer professional installation services.

Mulching technology for a healthier lawn

The iMOW® is fitted with three free-swinging, extra-sharp blades which provide a clean-cut lawn every time. These blades rotate each time they stop, meaning they last 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.

Dynamic mowing plans and intelligent features

You can build a dynamic mowing plan for your iMOW® which is tailored to your needs and programme 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, 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 its mowing plan, it finds its way back to its weather-proof docking station and charges itself efficiently, ready for the next time it goes out to cut.

Voice feedback and manual controls

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.

Important safety information: 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.
