How to Winterize a Navimow X4 (Complete Checklist)

Winterizing a Navimow X4 (the X430 and X450) is six steps, a handful of hand tools and an afternoon. Do it right and the mower wakes up in spring on the same map, on the same dock spot, with a healthy battery.

This is the exact checklist we run on our own X4s, in the order we do it, and it’s the one in the video above. Own a different robot mower? Our general winterizing guide covers any brand.

When is it time to winterize?

Watch the overnight lows in your weather forecast. When the lows are above 32°F but below 40°F for several days in a row, it’s time to winterize.

Don’t wait for the first hard freeze. Cold is hard on the battery, and you want the mower stored before temperatures drop below freezing.

What you’ll need

A hand screwdriver. No electric drivers: they make it too easy to strip or overtighten a screw.
A Torx screwdriver, only if you’re removing the battery for shed storage.
Protective gloves.
A brush and a damp cloth.
A garden hose. Not a pressure washer.
4 silicone marker pegs from the original box. Golf tees work too.
A plastic bag and a zip tie, for a wall- or roof-mounted antenna.
The original Navimow box.

Step 1: Charge it, then hibernate it

Leave the mower on the charging station until the battery is at 85% or higher.
In the Navimow app, tap Begin hibernating. This powers the mower off and uses less energy than a normal shutdown.
Make sure the mower is fully off before you handle the blades.

The Navimow app's Winter storage screen with its Begin hibernating button, beside a Navimow X4 being washed on the lawn — The Navimow app has its own Winter storage screen. Begin hibernating is the first thing we tap, so the mower is off before anyone reaches for a blade.

Step 2: Remove the discs and blades

Put on protective gloves.
Remove the cutting discs so you can clean all around them.
Remove the blades completely for the season.

Removing a cutting disc from a Navimow X4 with a hand screwdriver, the mower tipped on its side — A hand screwdriver, not a drill. With the discs off, every corner of the deck can be cleaned.

Step 3: Clean the mower

Hose off the top of the mower.
Wipe the underside with a damp cloth and brush out the grass and dirt.
Do not use a pressure washer.
Let the mower dry completely before you pack it.

Packed clippings left in the deck are trapped moisture sitting against the machine all winter. For the everyday version of this job, see how to clean a Navimow.

Step 4: Break down the charging station

Disconnect the power supply and bring it inside.
If you have a Navimow Garage, take the lid off.
Unscrew the 4 screws holding the charging station down.
Push a marker peg into each screw hole and leave them in the ground, so the dock goes back in the exact same spot.
Disconnect the charging station from the antenna cable.

Step 5: Protect the antenna

Wall or roof mount: leave it in place and cover it with a plastic bag, open end down, secured with a zip tie.
Ground pole: remove the antenna head and upper pole, and leave the bottom section in the ground.
Do not move the antenna base. Moving it means creating a new map in the spring.

The antenna’s spot is the one you worked hardest to get right (here’s why placement matters). Leaving the base exactly where it is keeps every boundary you drew lined up.

Step 6: Pack it and store it

Pack the mower, charging station, antenna, discs and cables back in the original box.

Best option: store the boxed mower in a heated area, like a basement shelf, between 41°F and 113°F.

If the mower stays in a shed:

Remove the Torx screws on the bottom of the mower.
Unplug the battery clips and remove the battery.
Store the battery inside, somewhere warm and dry.
Keep the mower dry and off the floor.

Why 85%, why hibernation, and how cold is too cold: winter battery storage has the reasons, beside Mammotion’s numbers.

Lifting the battery pack out of an upturned Navimow X4, its wire leads still attached, after removing the Torx screws on the bottom — Wintering in a shed: the battery comes out after a few Torx screws and spends the winter inside.

A Navimow X4 parked against the wall of a garage beside a stroller and a child's ride-on car — An unheated garage counts as a shed. Battery inside, and the mower dry and up off the concrete.

Spring startup

Reinstall the battery (if you removed it), the discs and the blades. Worn blades? Here’s the swap.
Set the charging station back on the marker pegs, and reconnect the antenna and power.
Charge the mower first, then power it on to wake it from hibernation.
Run a test mow and check that the map lines up.

The whole spring order, including the firmware update and the first mowing height, is in the spring startup guide.

The X4 winter checklist at a glance

☐ Lows between 32°F and 40°F for several days? It’s time
☐ Charge to 85% or more, then Begin hibernating
☐ Gloves on, discs and blades off
☐ Hose the top, cloth and brush underneath, let it dry completely
☐ Dock: power supply in, 4 screws out, pegs in the holes, antenna cable off
☐ Antenna: bag a wall or roof mount; on a pole, head and upper pole in, base stays
☐ Everything in the original box, stored between 41°F and 113°F (in a shed, the battery comes inside)

Frequently asked

When should I winterize my Navimow X4?

Watch the overnight lows in your forecast. When they sit above 32°F but below 40°F for several days in a row, it's time. Don't wait for the first hard freeze: cold is hard on the battery, and you want the mower stored before temperatures drop below freezing.

What battery level should a Navimow X4 be at for winter storage?

85% or higher. Leave it on the charging station until it gets there, then tap Begin hibernating in the Navimow app. Hibernation powers the mower off and uses less energy than a normal shutdown. Make sure it's fully off before you handle the blades.

Do I take the Navimow antenna down for winter?

Not the base. A wall- or roof-mounted antenna stays where it is, covered with a plastic bag (open end down) and a zip tie. On a ground pole, take the antenna head and upper pole inside and leave the bottom section in the ground. Moving the antenna base means creating a new map in the spring.

Can I store my Navimow in a shed or an unheated garage?

The best place is a heated area, like a basement shelf, between 41°F and 113°F, with the mower boxed. If it has to stay in a shed, take the battery out (Torx screws on the bottom, then unplug the battery clips) and store the battery inside somewhere warm and dry. Keep the mower dry and off the floor.

How do I put the charging station back in the same spot in spring?

Mark it before you lift it. After you unscrew the four screws holding the station down, push a marker peg into each screw hole and leave them in the ground. The silicone pegs come in the original Navimow box; golf tees work too. In spring the station goes right back on the pegs.

Can I pressure wash my Navimow before storing it?

No. Hose off the top with a garden hose, wipe the underside with a damp cloth and brush out the grass and dirt. Then let the mower dry completely before it goes in the box.
