Your iMOW® robotic mower needs weekly care and attention to keep it performing at its best. Find out how to clean it correctly.
We recommend cleaning your robot lawn mower weekly, though in rainy weather it will get dirty more quickly and need more frequent attention.
Your robotic mower needs regular cleaning to stay in peak condition – particularly during the grass cutting season and before extended breaks in use. Making sure to remove any plant residue or sap on a regular basis will ensure a clean cut for your lawn, as well as a long life for your mower.
We explain in five steps how to clean your robot mower:
Before cleaning, leave it to cool down for approximately five minutes. Lock the mower by pressing and holding the STOP button for 5 seconds and selecting “Lock iMOW” under the Commands or Safety menu; this will ensure your robotic mower doesn’t start up while you are cleaning it.
Place your iMOW® on a firm, level surface. Remove all dirt from the exterior, using a damp cloth or soft-bristled brush to avoid scratching the hood.
Do not use aggressive cleaning agents! These may damage the metal or the plastic surface. Do not clean your mower under running water or with a high- pressure cleaner or garden hose.
To make cleaning the underside of the machine easier, tip the robot mower onto its side and lean it against a wall.
Remove the mowing blade by pushing in the tabs on the carrier plate with one hand and loosening the fastening nut with the other.
Remove the carrier plate and clean the area underneath it with a brush. It is especially important to do this when the mower has been working after wet weather, as the wet dirt hardens between the plate and the mower unit housing. This can increase power consumption and make the mower noisier.
Clean the carrier plate and blade. Any grass stuck to the blade can be cleaned off using a wooden stick. Be very careful when cleaning the blade!
STIHL pro tip: Silicone or wooden kitchen spatulas are good tools for cleaning a robot mower, as they are sturdy enough to remove stubborn dirt without scratching the mower housing. Flexible silicone spatulas are great for cleaning in corners and curves.
When cleaning your robotic mower you should check the mowing blade for wear. We recommend replacing the mowing blade after every 200 operating hours; your iMOW® will automatically alert you when it’s time.
STIHL pro tip: When your blade gets blunt and is no longer cutting cleanly, it’s time to replace it. Never sharpen the iMOW® blade, always replace it. This will ensure that your robot mower works correctly and runs quietly.
Unplug the docking station. Wipe the charging surface with a damp cloth. Clean the contacts that connect the mower to the charging station if necessary, using a microfibre cloth or a soft-bristled brush.
Reassemble all the pieces of your mower after cleaning:
Slide the carrier plate onto the blade shaft.
Place the mowing blade and the fastening nut on top of the carrier plate. Make sure the retainers are sitting correctly in the mowing blade holes and screw in the fastening nut until you hear a click.
Carefully check the mowing blade is sitting correctly and installed firmly.
Put the mower back on its wheels and wheel it into the docking station. Press the symbols shown on the display to reactivate the iMOW®.
Cleaning and reassembly is finished, and your mower is ready for the next cut.
