Off Season Robot Mower Storage at the Home Yard: A Winter Guide

How should you store a robot mower over winter at home?

Clean the mower, charge the battery to the level its own manual names, and keep the mower and its charging station indoors, above freezing and away from wet weather. That covers most of the job. The details vary by brand, and the battery target is where the brands disagree most.

As of November 2026, the vendor pages we checked gave different battery targets. Mammotion says to store at 80% or higher and top up to at least 80% at intervals of no more than 90 days. Einhell advises 30% to 60%, shown as two lit LEDs on the charge indicator. Eufy says about 50% to 80%, depending on the model.

Vol.at, an Austrian consumer article, reports that some manuals call for 40% to 60% in extended storage while others require a full charge. It also reports that Worx warns a drop to 0% can damage the battery. Whatever the number, do not let the pack run flat.

Why do the charge targets differ so much?

The sources we gathered do not explain the gaps, so do not assume one brand's figure carries over to another. Husqvarna tells owners to fully charge and switch off before storage, which sits far from Einhell's 30% to 60% range. Each vendor writes for its own mower, so the manual for your exact model should set the target.

Mammotion gives the most concrete schedule in the research. Put a reminder on the day the mower goes in, then another every 90 days, so the battery is not left untouched for the whole winter.

What cleaning and blade care should happen before storage?

Clean the mower before it goes in. Brush clippings, mud and debris off the deck, the wheels and the sensors. Leftover organic residue can hold moisture and lead to corrosion, which is a good reason to finish this before the first hard freeze rather than in spring.

Blades deserve the same attention. Several manufacturers recommend replacing dull or damaged blades before storage, so the mower cuts cleanly when it returns to the lawn. Husqvarna's guide advises fitting new blades and screws, which it says prevents rust and keeps edges sharp.

Doing this work in autumn means the first spring mow starts from a known blade condition, not a guess.

Where should the mower wait out the cold?

Indoors, above freezing, is the common instruction. Husqvarna says to store its mower and charging station indoors above freezing, in a garage, shed or basement. Mammotion asks for a dry, frost free spot, ideally between 10°C and 20°C, with its charging station brought in as well.

Mammotion's wider storage range runs from minus 10°C to 40°C, and it says to bring the mower indoors once outdoor temperatures fall below minus 10°C. Those figures are not the same as Husqvarna's above freezing rule, so the stricter reading is the safer one for a home yard. Navimow adds that an unheated garage can be too cold, and its charging station should come indoors or stay sheltered.

The test is simple. If the garage or shed can drop below freezing overnight, the mower belongs in a heated room or a basement that stays above freezing through the coldest weeks.

How do you keep a stored mower secure and easy to reach?

The sources we gathered give no verified guidance on securing a stored robot mower at a home yard, so the points below are planning choices, not manufacturer rules. Start with the bay itself. Pick a space that locks, stays dry, and can be reached in spring without moving other equipment first.

Route the charging cable so it does not cross a walkway or doorway where someone could trip on it. Keep the mower, its charging station and the app login details in one place, so setup can be restored quickly when the mower comes out. Decide ahead of time who else can reach the bay, because a shared garage calls for a different plan than a closed room.

What should you check before the mower goes back out?

Mammotion suggests installing firmware updates during the off season. Doing that on a mild indoor day gives the mower up to date software before the first mow, rather than during the morning it is needed.

Then check the charge level against the manual's target, wipe the deck once more, and confirm the blades are sharp and secure. A short run in a small test area before the full lawn shows whether anything has changed over the winter.

Where storage planning meets commercial mowing

Storage is a site question, and it grows when a contractor runs several mowers across client properties. Each site needs a dry, frost free place for the mower and charger, a bay that locks, and a clear route for the spring restart. The vendor guidance above is written for individual models, so confirm each unit's manual before setting a schedule across a fleet.

Service Robot Co. is an OEM neutral integrator. We lease commercial robots on a three year lease with one fixed quote after a site assessment, then deploy, train and service them under RoboCare, our service plan, backed by regional service engineers. If you are weighing robot lease options for mowing or cleaning, storage bay questions belong in the same conversation as access and charging, before a quote is made.
