Roborock S8 roller / main brush kit (hair + pickup upgrade)
Rollers and brush assemblies wear over time. Replace when pickup drops or noise increases.

Fit check

Replacement schedule (realistic)
This is a practical baseline. High dust, pets, long runtime, and carpets shorten the timeline.
| Part | Typical cadence | Notes |
|---|---|---|
| Filter | Every 1–3 months | — |
| Side brush | Every 3 months | — |
| Main brush | Every 6–12 months | — |

Fit checklist (avoid wrong orders)
- Mixing S8 vs S8 Pro Ultra parts with look-alike listings.
- Assuming 'universal' pads fit (some do, many don’t).
- Replacing brushes but not checking for hair wrapped around end caps.

FAQ
Should I clean or replace my robot vacuum filter?
If the filter is lightly dusty and the manual allows gentle cleaning, you can extend life a bit. Replace when it stays gray, smells, or airflow doesn't recover. A worn filter often looks fine but performs poorly.
Why does my robot vacuum start to smell?
Odor usually comes from a clogged filter, dirty bin seals, hair buildup near the brush housing, or (on mopping models) a damp pad left too long. Replacing the filter and fully drying any washable parts is often the fastest fix.
Do 'universal' replacement kits work?
Sometimes, but model-specific kits are safer. 'Universal' listings can be close-but-not-quite in tab placement or thickness. Use the fit checklist below and compare listing photos to your existing part.
