The Complete Roborock Qrevo S Pro Accessory Guide

The Complete Roborock Qrevo S Pro Accessory Guide
The Roborock Qrevo S Pro has ten wearable parts: a main roller brush, two side brushes, a HEPA filter, a water tank filter, mop pads, a mop pad plate, a main brush cover, dust bags, a dust bin, and universal wheels. Each one wears out on a different schedule, and replacing them on time is the difference between a robot that still cleans like new and one that smears, leaves dust lines, or loses suction.
This guide covers what every Qrevo S Pro part does, when to replace it, how to install it, and where to get it — so you can keep the robot performing the way it did on day one.

Your schedule will land at the short end if you have pets, carpets, or a large home — at the long end for a small apartment with hard floors. The Roborock app also tracks usage hours and will prompt you when a part is due, which is a good backstop but not a substitute for a quick visual check once a month.
1. Main roller brush
The rubber roller brush is the part that takes the most abuse. Long hair wraps around it, carpet fibers wear down the fins, and over time it stops agitating dirt out of the carpet pile.
Replace it when: the rubber fins look flattened or torn, the brush rattles on hard floors, or you have to re-vacuum areas it used to clean in one pass.
How to replace it:
- Flip the robot over and press the two clips on the main brush cover to lift it off.
- Lift the roller out by its end cap — untwist any wrapped hair first.
- Wipe the brush compartment and the two end bearings clean.
- Seat the new roller so both ends click into place, then snap the cover back on.
A two-minute clean of the bearings and axle each time you empty the bin will nearly double the roller brush's life.
2. Side brushes
Side brushes sweep wall edges and corners toward the main suction path. They're cheap and wear fastest — the bristles splay outward and the brush starts flicking debris away instead of toward the robot.
Replace both at the same time. A fresh brush on one side and a worn one on the other makes the robot track unevenly along walls.
How to replace: flip the robot, grip the brush, and pull straight up — it snaps off its mount. Press the new one on until you feel the click. No tools needed.
3. HEPA filter
The HEPA filter traps the fine dust that would otherwise pass through the bin and back into your air. A clogged filter is the single most common cause of weak suction.
Rinse it every two weeks: tap the dust out, rinse under lukewarm water until it runs clear, and let it dry for at least 24 hours before reinstalling. Never put a damp filter back in the robot — it will clog immediately and can grow mold.
Replace it when: rinsing no longer restores the color, the pleats stay gray, or suction stays weak with a clean dust bag and bin.
4. Water tank filter
This small inlet filter sits where water enters the mopping system and keeps mineral deposits and debris from clogging the pump and pad moistening mechanism. It's the most forgotten part on the robot.
Rinse it monthly under running water and check that water flows through freely. If it stays discolored or the flow slows even after rinsing — or the pads come out unevenly wet — replace it. A clogged tank filter is a common cause of "the mop barely wets the floor" complaints.
5. Mop pads
The Qrevo S Pro's dual spinning mop pads do the actual floor scrubbing, and they degrade gradually enough that many owners don't notice the decline. Worn pads smear rather than scrub, and they hold less water.
Wash after every mopping session — warm water, mild detergent, air dry completely. Skip fabric softener; it coats the fibers and reduces absorbency.
Replace when: the surface looks shiny and smooth instead of fuzzy, edges fray, or streaks remain after a full mopping pass even with fresh water and solution.
6. Mop pad plate
The plate is what the pads Velcro onto, and it spins at high RPM the whole time the robot mops. Two things go wrong: the Velcro loses its grip so pads fly off mid-cycle, or a cracked plate vibrates and leaves circular scuff patterns on the floor.
Replace when: pads detach during mopping, you hear a rattling from underneath, or you can see hairline cracks in the plate. It's a cheap part and a five-minute swap: peel the old pads off, unlatch the plate from the module, click the new one in, press new pads on.
7. Main brush cover
The brush cover holds the roller at the right height against the floor and seals the suction channel. Its clips are the failure point — they fatigue over months of opening and closing for brush cleaning.
Replace when: a clip has snapped off (the cover won't stay closed and the brush lifts away from the floor), or the rubber seal along the edge is flattened and the robot leaves an un-vacuumed strip in the middle of its path.
8. Dust bags
The auto-empty dock pulls everything the robot collected into a disposable bag. In a typical home one bag lasts four to eight weeks; with shedding pets, plan on monthly.
Don't wait until the bag is packed solid — an overfilled bag strains the dock's vacuum motor and can split. Pull the bag out by its cardboard collar, close the rubber seal, and discard. Seat a new bag fully onto the inlet before closing the dock cover; a half-seated bag leaks fine dust back into the dock.
9. Dust bin
The dust bin itself rarely wears out, but the clear plastic cracks around the latches and the gasket flattens with age, which is when fine dust starts leaking back onto the floor instead of going into the dock.
Replace when: you see dust lines where the robot parks, the bin rattles in its slot, or a crack is visible near the latch. Until then, wash the bin monthly and keep the gasket groove free of compacted dust.
10. Universal wheels
The small caster-style universal wheels let the robot pivot and climb thresholds. Hair wraps tightly around their axles, and the housings wear into an oval shape over time.
Clean monthly: pull out the wheel, cut away wrapped hair, and wipe the axle. Replace when: the robot wobbles or lists to one side, drags or scores the floor, or a wheel no longer spins freely after cleaning.
Floor cleaning solution
Mopping with plain water leaves grease and sticky residue behind. A proper floor cleaning solution breaks that grime down so the mop pads can actually lift it — and since the dock washes the pads with water from the same tank, what you put in that tank matters.
The EcoCleanPath Cleaning Solution (1L, $15.99) is a plant-derived, low-foam formula made for robot vacuum mopping systems. It won't clog the pump or leave streaks, one bottle lasts months of regular mopping, and it fits every Roborock model — not just the Qrevo S Pro.
How to use it: pour a small amount into the clean-water tank before a mopping run and let the robot do its normal cycle. Skip regular household detergent — those formulas foam too much and can damage the pump over time.
Best value: the accessory kit
If two or more parts on this page are due at once — which is common, since they age on similar schedules — the Accessory Kit for Roborock Qrevo S Pro at $29.99 bundles the consumables together for less than buying them one by one. It's the option most owners pick for a once-a-year refresh.
Signs your Qrevo S Pro needs new parts (before the app says so)
- Weak suction, dust left behind → HEPA filter or dust bag first, then check the dust bin gasket
- Streaks or dry patches when mopping → mop pads, then the water tank filter
- New rattling or vibration → roller brush bearings or a universal wheel
- Pads flying off mid-cycle → mop pad plate Velcro
- Dust leaking around the dock → dust bag seating, or a cracked dust bin
Frequently asked questions
Are these original Roborock parts? The parts linked on this page are premium aftermarket replacements built to the same fit and performance specifications, at a fraction of the original-brand price. Every part is checked for exact fitment with the Qrevo S Pro before shipping.
How often should I do maintenance on the Qrevo S Pro? A two-minute routine every time you empty the bin (check brush, tap out the filter), a monthly deep clean (rinse filter and tank filter, wash bin, clean wheels), and part replacements per the schedule table above.
Can I wash the HEPA filter? Yes — rinse it under lukewarm water every two weeks and let it dry for at least 24 hours. Replace it entirely every 6–12 months depending on use.
Do Qrevo S Pro parts fit other Roborock models? Not reliably. Roborock revises consumable designs between series, so always match the part to your exact model. Every part page on this site lists its confirmed compatibility.
One dust bag lasts how long? Typically 4–8 weeks in an average home. With multiple pets or heavy sanding-season dust, check monthly and replace when the bag feels firm to the touch.
