# Mop Roll Worn Out error

## If Matic shows a "Mop Roll Worn Out" error, this is usually caused by wear on the mop roll or an assembly issue. The steps below will help you resolve it.

### Step 1: Check the Mop Roll

If the mop roll looks worn, frayed, or flattened, try washing it under running water and letting it dry fully. This can help it fluff back up. If it still looks worn after washing, replace it.

We recommend replacing the mop roll every 1–3 months depending on use. You can order a replacement mop roll [here](https://maticrobots.com/accessories/mop-roll).

⚠️ Whenever you reinsert a dried mop roll or install a replacement, go to **Settings \> New Mop Roll Inserted** so Matic knows to fully saturate it before the next mopping session.

### Step 2: Check Alignment and Assembly

Remove the mop roll and reinsert it, pressing firmly until it clicks into place. The white handle should sit flush in the cavity.

#### If the error keeps coming back

The mop roll is made up of three parts — the idler(white handle), core, and mop roll. The error can return if any of them is broken, not fully assembled, or became dislodged during a cleaning cycle.

Remove the mop roll and fully disassemble it into its three parts. Check each one for visible damage and make sure everything reassembles correctly before reinserting.
