Mammotion Robot Mower Maintenance: A Season-by-Season Guide

A Mammotion Luba or Yuka does the mowing so you don't have to — but "robot" doesn't mean "no upkeep." A handful of small jobs spread across the year keeps the cut clean, the sensors seeing clearly, and the machine running for seasons instead of just summers.

Here's what to do and when — with Mammotion's own numbers — plus straight answers to the two questions owners ask most: how often to change the blades, and how to clean underneath without wrecking the robot (or your back).

🌱 Spring — waking it up

After a winter in storage, don't just send it straight back out. Run through this first:

• Wipe it down and inspect the body, wheels and sensors for cracks, grime or pest damage from storage.
• Check the cutting blades. If they were put away dull, bent or rusty, replace them now — fresh blades at the start of the season pay for themselves in cut quality and motor wear.
• Inspect the cutting disc itself for cracks or wobble.
• Charge fully, update the app and firmware, and run a short test mow before trusting it on the whole lawn.

Spring is the cheapest time to catch small problems. A cracked disc or worn blade found now is a five-minute fix — not a mid-season breakdown in peak grass.

☀️ Summer — keeping the cut clean

This is when the robot works hardest, and when two jobs matter most.

Blades. Dull blades don't cut grass, they tear it. You'll see browned, frayed tips a day or two after mowing, and the motor works harder for a worse result. Mammotion's blades are double-edged, so the guidance is to flip them at around 50 hours of mowing and replace them by roughly 100–150 hours (their figure, measured on tough Zoysia grass — softer lawns often go a little longer). In plain terms, most owners change blades once or twice a season, depending on how much they mow.

The fastest way to stay on top of it is to keep a second cutting disc, pre-loaded with fresh blades, on the shelf. When the mounted set goes dull, you pop the whole disc off and the spare on in under a minute, then re-blade the dull one whenever it suits — coffee in hand, off the clock, not mid-mow with the grass getting away from you. Sharp lawn, no weekend pit-stops, and neither you nor your better half left waiting on a robot to finish before the guests arrive. Happy blades, happy lawn, happy spouse. It also covers you for the bit nobody mentions: Mammotion's own discs have a habit of being out of stock exactly when you need one.

Cleaning underneath. Grass clippings pack into the underside, especially around the disc and wheels. Left there, they trap moisture (which rusts blades and hardware), throw the disc off balance, and steadily drag down cut quality. Two rules, both straight from Mammotion:

1. Power it off first, then clean with a soft brush or a low-pressure hose. Never a high-pressure washer — Mammotion is explicit that it forces water into the electronics. After cleaning, stand it upright and let it dry for at least 30 minutes before it mows again.
2. Protect the camera. Mammotion tells you to support the body when you tilt the mower so the vision module never takes the weight or touches the ground. That's exactly why balancing a heavy robot on its nose or against a wall is asking for trouble — and why a purpose-built stand earns its keep. It holds the machine upright and steady, sensitive camera and LiDAR safely off the deck, with the underside facing you for a proper brush-out. Two-minute job instead of a wrestling match.

🍂 Autumn & winter — putting it away right

Storing it dirty is how you guarantee a rough spring. Mammotion's winter routine, in short:

• Disable all scheduled tasks in the app so it can't wander off mid-service.
• Charge the battery to around 80–100% for storage.
• Deep-clean the whole machine — shell, wheels, chassis and underside — and let it dry completely.
• Tilt it up (camera supported), remove the blades and cutting plate, brush everything down, and check the lifting seal sleeve for damage.
• Store it indoors, dry and frost-free — Mammotion specifies roughly -10 to 25 °C — along with the charging station and RTK reference station.

❓ Quick answers

How often should I change Mammotion blades? Mammotion's figure: flip the double-edged blades at about 50 hours of mowing and replace them by roughly 100–150 hours — in practice, once or twice a season for most lawns. Swap sooner if the cut looks torn rather than sliced, or if a blade is bent.

How do I safely clean under my robot mower? Power it off, then tilt it upright on a stand so the underside faces you and the camera isn't bearing weight. Brush out the packed grass around the disc and wheels with a soft brush or low-pressure hose — never a high-pressure washer — then stand it upright to dry for 30 minutes before it runs again.

Do I have to remove the blades for winter? Mammotion's winter routine has you remove the blades and cutting plate for a full clean and inspection. At minimum, replace anything worn before storage so it's ready to mow in spring with no surprises.

Can I change the cutting disc myself? Yes — it's just a few screws. Keeping a spare disc means you swap it in seconds and re-blade the old one whenever it suits you.

Two things make every job above easier: a spare cutting disc so you're never waiting on stock, and a service stand so cleaning and blade changes take minutes instead of muscle — with your camera and LiDAR kept safely off the ground, exactly as Mammotion recommends.
