When winter comes, it’s time to prepare the robotic lawn mower for the cold season. This is important to avoid damage to the device or a failure when starting the new season. Some mistakes occur repeatedly when winterizing the mower—and they can be easily avoided.
1. Mistake: Storing the Mower Without Cleaning
A frequently overlooked point is thorough cleaning before the winter break. If grass clippings, soil, or moisture remain on the device, it can lead to corrosion on blade screws and charging contacts over the winter months, as the manufacturer Segway informs. Wheels or sensors can also be blocked by dried-on dirt and may not function in the spring.
Important: Before storing, all visible areas should be cleaned—mainly the underside, blades, wheels, and contact surfaces. Avoid using a pressure washer to prevent damage to electronics and seals.
2. Mistake: Mishandling the Battery
Another classic mistake when winterizing the mower is mishandling the battery. Storing a lithium-ion battery empty or leaving it outside in frost can significantly shorten its lifespan. Low temperatures or deep discharge are problematic for batteries.
The manufacturer Einhell recommends fully charging the battery before storage and then storing it with a charge level of about 30 to 60 percent. Ideally, remove the battery from the device. During the winter months, it’s advisable to check the charge level once or twice to avoid deep discharge.
Important: The battery should be stored in a dry, dust-free, and cool place with a temperature of about 59 to 68 degrees Fahrenheit—ideally indoors or in an insulated shed. It’s also important to protect the battery from frost, moisture, heat sources, and direct sunlight. This way, the battery can be safely and gently stored over the winter.

3. Mistake: Forgetting the Charging Station During Winterization
Another mistake is bringing the mower indoors for winter but leaving the charging station outside in the garden. Moisture, frost, and dirt affect the device as well as the often-forgotten charging station.
Important: A dry, frost-free storage location is recommended—such as a basement or garage—for both the mower and the charging station. These should also be cleaned and stored protected so they are ready for use in the spring without any issues.
4. Mistake: Wrong Timing for the Last Use
Not only winterizing, but also the last use of the mower can involve mistakes. Mowing too late in the year or under poor conditions, such as frost or waterlogged soil, risks damage to the lawn and the device. Additionally, if the grass is too long, the clippings remain on the surface—a breeding ground for fungi or rot.
Important: Before the winter break, the last mowing should be done in a timely manner, considering weather and soil conditions. The cutting height should also be set correctly so the lawn is neither too short nor too long going into the cold season.
How the Mower Survives Winter Without Damage
“With careful preparation, not only can the mower’s lifespan be extended, but a smooth start to the next season is also ensured. Knowing and avoiding the most common mistakes effectively protects the device from damage due to cold, moisture, or improper storage.”
