The RMI 522 C iMOW® robotic mower is the ideal choice for you if you have a medium-sized garden and want to keep your lawn in check with no effort.
This automatic mower is easy to use and also helps to improve your lawn whilst mowing it. This is thanks to the mulching blade, which shreds the grass into small piece and drops it back on to the lawn as a natural fertiliser. This also means the added bonus of not having to empty the grass box either. You can programme the RMI 522 C to mow when you want it to but it has a dynamic mowing plan so it can adjust itself if for any reason it cannot mow on certain days. So if it rains one day, it will make up the mowing time on the next day, which means your lawn never looks unkempt or overgrown. The iMOW® is also designed to mow your lawn efficiently in the shortest time possible.
The new direct drive home function allows the iMOW® to drive directly to the dock instead of following the perimeter wire home. This reduces the wheel marks around the lawns perimeter, and allows the iMOW® to travel efficiently around the garden. Direct drive home works best in lawns with fewer obstacles and mowing areas - if you’re unsure, we recommend consulting your nearest STIHL iMOW® dealer for more information.
The RMI 522 C can be used to mow lawn areas up to 2,100m² and gradients up to 40%. Compatible with the iMOW® app, the settings on the RMI 522 C robotic mower can be easily adjusted on your smartphone or tablet. You can quickly change the mowing plan, read status messages and pause or start new mowing operations wherever you are.
Please note that this does not include everything you need to install your iMOW®. You will also need an installation kit, which includes perimeter wire, fixing pins and wire clips.
iMOW® robotic mowers are not toys. During the iMOW® robotic mower's active times, children, bystanders and animals must be kept out of the working area. Please refer to the operating instructions for further information.
FeaturesDynamic mowing plan
When you set up the mowing plan of your iMOW® robotic mower, you can set the activie timeframe during which the iMOW® can operate. Within these windows of active time, the automatic lawn mower will work out the best times to mow for an optimum result. If it has to stop mowing because of rain, it automatically catches up later within the specified time window. You can set the mowing plan via the control panel, or via the iMOW® app.
The iMOW® app can be used to easily update or change any settings on your RMI 522 C whether at home or on the move. This is really useful if you want to send the iMOW® out to mow earlier than scheduled, or delay it till later so you can enjoy using your garden instead. It also works in conjunction with online weather forecasts to make sure that the iMOW® only mows in suitable weather conditions.
The iMOW® has a movable hood with sensors which helps to protect the robotic mower from obstacles. If the iMOW® robotic mower comes up against an obstacle, such as a garden chair left on the lawn, during automatic mowing, the integrated sensors detect contact with the object and changes direction.
The smooth-running wheels have a traction pattern that helps the STIHL iMOW® robotic mower move with precision, even on hilly areas. The RMI 522 can cope with gradients of up to 40%. The wheels of the automatic lawn mower are also self-cleaning.
Adaptive slope speed
The adaptive slope speed technology means that the STIHL iMOW® robotic mower can adapt its speed on uneven terrain. The mower has an integrated tilt sensor which continuously analyses the position and adjusts its speed as necessary.
Direct drive home
Direct drive home function allows the iMOW® to drive directly to the dock at the end of each mowing session instead of following the perimeter wire home. This reduces the wheel marks around the lawns perimeter, and allows the iMOW® to travel efficiently around the garden.
Easy-to-use control panel
The control panel of the STIHL iMOW® robotic mower features a large LCD display, which is easy to read even in bright sunlight and intuitive to use.
FAQsQWhat happens if there is an obstacle on the lawn?
A: If the iMOW® robotic mower comes up against an obstacle during automatic mowing, the integrated sensors detect contact with the object and the mower simply changes direction. However, the mower does have a sharp mowing blade and children, pets and bystanders should not be in the working area at the same time as the iMOW®.
QWhat is included with the iMOW®?
A: The iMOW® robotic mower comes with the docking station, four pegs for securing the docking station to the ground and an iMOW® ruler which is used during installaton when laying the perimeter wire. The perimeter wire and pegs are available in a separate installation kit that is not included with the iMOW®.
QCan someone steal the iMOW®?
A: It is possible to pick up the robotic mower, but all iMOW® robotic mowers can have a 4 digit pin code activated that prevents other people from being able to use the machine. If the iMOW® is picked up, an alarm sounds and automatic mowing is turned off unless the pin is entered within one minute. Additionally all C models can be located via the iMOW® app using the built in GPS receiver.
QCan the iMOW® stay outside all year round?
A: Over winter, we recommend storing the iMOW® itself in a secure, dry place. Before you do this, you should fully charge the iMOW® battery, switch off the automatic mowing system and set the iMOW® to its highest security level. The docking station can remain in the garden over winter and does not need to be removed, but the power cable should be disconnected from the mains and the docking station during the period when it is not in use. In extreme weather you can cover the docking station if you wish to, with a secure storage box or similar.
QDo I have to empty the grass box?
A: No, the iMOW® is a mulching mower so it shreds the grass clippins finely and drops them back into the grass as a nutrient-rich, natural fertiliser. So over time, the robotic mower will also improve your lawn too.
QDoes the iMOW® work in the rain?
A: The iMOW® robotic mower has in-built rain sensors but you can set the rain sensitivity level on your mower yourself. Depending on the level of sensitivity chosen, the iMOW® will only mow if conditions are almost or completely dry. We do recommend setting it so that the mower operates in mostly dry conditions as this stops the iMOW® from getting dirty and protects the roots of your lawn. If you have set it like this and the rain sensor is activated on the iMOW®, it will stop mowing when it starts to rain and return to its docking station. When the rain stops, it automatically will resume mowing the lawn. If it rains through the entire active time, the dynamic mowing plan allows iMOW® to make up for lost time on a different day. For example, if it rains on a Monday then it may make up the time on the Tuesday instead.
QHow short will iMOW® cut the grass?
A: The iMOW® has multiple different heights settings from 20mm to 60mm, which can be easily adjusted on the mower.
QHow does the iMOW® work?
A: The iMOW® operates within a perimeter wire that you set up when you install the mower. The signal generated by the wire tells the iMOW® where to mow so it's important to make sure the wire is installed correctly. If you have a particularly complicated garden layout, you may want to get one of our STIHL Approved Dealers to install the iMOW® for you instead. You can find your nearest iMOW® specialist STIHL dealer here.
QCan I install the iMOW® myself?
A: You can install an iMOW® yourself. There are instructions on how to do this in the User Manual. We also have a video guide showing you to how to install your iMOW®. However if you would prefer not to install it yourself, we recommend ordering your iMOW® from one of our STIHL Approved Dealers as they can also carry out the installation for you. You can find your nearest iMOW® specialist STIHL dealer here.
Tips#1Cleaning your iMOW®
To clean your iMOW® you should disable it first, then clean it with a brush or damp cloth. You can find full instructions for how to to do this in our video
#2Storing your iMOW®
If you do not plan to use your iMOW® for an extended period of time, such as over winter, you should fully charge the iMOW® battery, switch off the automatic mowing system and set the iMOW® to its highest security level. Depending on your iMOW® model, you can also set it to hibernation mode. The mower should then be stored in a secure, dry place, such as a garage. The docking station can remain in the garden over winter and does not need to be removed, but the power cable should be disconnected from the mains and the docking station during the period when it is not in use.
#3Cutting height on your iMOW®
When the weather is hot and dry, we recommend that you select the highest cutting height on the iMOW® so that the ground doesn’t dry out so fast and the lawn doesn’t burn from the heat.
