Roborock S7: replacement filters & parts that actually fit

Roborock S7 owners typically replace the main brush, side brush, filters, and mop pads on a regular cadence. Mop pad quality matters—better pads can improve streak-free performance and reduce odor buildup.

Fast win

If performance dropped suddenly, start with the filter. Filters clog gradually, so the decline can sneak up on you.

Compatibility trap

Kits are often labeled “fits many models”. Use the fit checklist below and compare the frame shape + tabs to your current part before buying.

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	Washable on many units; still replace periodically.
Mop pads	Every 1–2 months	Replace sooner if fraying or persistent odor.
Main brush	Every 6–12 months	—

Filter timing details Clean vs replace

Fit checklist (avoid wrong orders)

Ordering S8 pads/brushes for an S7 (and vice versa).
Choosing pads that are too thin (reduced pickup) or too thick (fit issues).
Ignoring filter frame differences between revisions.

Where to find your exact model

Flip the unit over and look for the label near the wheels or charging contacts. If your model has a “Plus” dock version, replacement parts are often the same — but always confirm the part shape.

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.
