When should you winterize a robotic lawn mower? 3 simple criteria

A robotic lawn mower makes garden work much easier—but every autumn the same question arises: When is the right time to winterize the mower?
Putting a robotic lawn mower into winter storage on time protects its battery, electronics and mechanical components and ensures it is ready to work again in spring.

This article explains when to winterize a robotic lawn mower, which temperatures matter and which modern features can make winter preparation easier.

Why the right time for winter storage is so important

Choosing the right time largely determines how well the robotic mower gets through winter. Waiting too long can cause:

• frost damage to the battery
• corrosion of the electronics and cutting system
• moisture damage inside the chassis
• unnecessary strain on the drive system

To avoid these problems, keep a close eye on outdoor conditions and temperatures.

The best time: when should you winterize a robotic lawn mower?

The best time is determined not by the calendar, but by grass growth and the weather.

1. As soon as the grass stops growing

The robotic mower can be stored once the grass is barely growing. This is usually the case when:

• average temperatures remain below 10 °C
• the lawn remains almost unchanged for several days
• the nights become noticeably colder

In most regions, this point falls between late October and mid-November.

2. No later than when frost threatens

As soon as night frost occurs regularly, the robotic mower should no longer operate outdoors.
Cold reduces battery performance and can cause permanent damage.

3. Heavy rain and waterlogged ground

In late autumn, the ground is often soft and heavy. This puts strain on:

• the drive motors
• the wheels
• the cutting system

Even if temperatures are still somewhat mild, an overly wet lawn can be a sign that the mower should enter winter storage earlier than planned.

The final lawn cut before winter

Before storing the robotic lawn mower, cut the lawn one final time to about 4–5 cm. This helps prevent:

• fungal disease
• snow mold
• weakening of the turf

After that, the mower is ready for winter storage.

Modern assistance: Navimow winter storage mode

Some manufacturers now make winter preparation much easier.
With a recent software update, Segway introduced a dedicated winter storage mode that actively guides users through the preparation process.

How to winterize the mower correctly—step by step

Choosing the right time is one thing; following the right procedure is another.
To help the robotic mower get through winter safely, you should:

• clean it thoroughly
• care for the battery properly
• store it somewhere dry and frost-free
• disconnect the charging station from power and store it safely as well

Conclusion: nature determines the ideal time for winter storage

The right time to winterize a robotic lawn mower depends on three factors:

1. Temperatures below 10 °C
2. Barely visible grass growth
3. The first frosty nights

Anyone who follows these signals and stores the robotic mower correctly will maximize its service life and enjoy a trouble-free start to the garden season in spring.
