View replacement filters on Amazon ↗
Fit: The Roborock Amazon listing explicitly names the S8 Pro Ultra in its compatible-model list.
Replace when: Roborock recommends replacing the washable robot filter every 6–12 months, or sooner if it is damaged or remains clogged after cleaning.
Before buying: This is the air filter in the robot dustbin, not the separate water filter in the dock. Select the two-filter white Filter-A option. After rinsing, let the filter air-dry for at least 24 hours before reinstalling it.
Third-partyPELLYDA
Roborock S8 Pro Ultra replacement dual main brushes
Two sets of dual main-brush replacements in the selected “Main Brush Replacement for roborock S8” option.
View dual main brushes on Amazon ↗
Fit: The PELLYDA Amazon listing explicitly includes Roborock S8 Pro Ultra in the selected S8 dual-brush option.
Replace when: Roborock recommends cleaning the main brushes every two weeks and replacing them every 6–12 months, or sooner if a brush or end fitting is damaged.
Before buying: S8 Pro Ultra uses two short rollers as a set, not one full-width roller. Choose the S8 option, compare both brush ends with the originals, and treat this as a third-party fit claim; we have not physically fit-tested it.

Roborock S8 Pro Ultra replacement side brushes
Two black Roborock robot side brushes.

Fit: Roborock's Amazon listing title and compatibility details explicitly include S8 Pro Ultra.
Replace when: Roborock recommends cleaning the side brush monthly and replacing it every 3–6 months, or sooner if bent or damaged.
Before buying: This is the screw-mounted brush on the robot underside. Compare its shape and screw fitting with your existing part; it is separate from the two main rollers and the dock's cleaning brush.
Third-partyKGC
Roborock S8 Pro Ultra replacement mop pads
Six gray washable microfiber mop pads in the selected six-piece option.
View mop pads on Amazon ↗
Fit: The KGC Amazon listing says these dual-sonic pads fit the S8 Pro Ultra only. Roborock's manual confirms this model's VibraRise 2.0 mop system; the seller's fit claim has not been physically tested by DustMigo.
Replace when: Clean the mop cloth after each use. Roborock recommends replacing it every 3–6 months, or sooner if worn or no longer attaches securely.
Before buying: This is a third-party cloth-only pack; it does not include the mop mount. Confirm the gray VibraRise 2.0 pads match your original attachment surface. The replacement interval printed in the seller listing differs from Roborock's manual, so follow Roborock's 3–6 month guidance and inspect wear.

Roborock S8 Pro Ultra replacement dock dust bags
Six original disposable dust bags; Amazon lists each bag at 2.5 liters. The selected option is “2-Dust Bag.”
View dock dust bags on Amazon ↗
Fit: Roborock's Amazon listing explicitly names S8 Pro Ultra. Its official U.S. store lists the same six-pack for this model.
Replace when: Replace the disposable bag when it is full, as directed in the S8 Pro Ultra manual.
Before buying: These bags are for the S8 Pro Ultra Empty Wash Fill Dock (EWFD07LRR/EWFD08LRR), not the robot dustbin or a different auto-empty dock. Confirm the selected six-pack and 2.5 L capacity before ordering; install a bag before the dock auto-empties.

Roborock S8 Pro Ultra replacement dock cleaning brushes
Two Roborock high-speed cleaning brushes for the Empty Wash Fill Dock.
View dock cleaning brushes on Amazon ↗
Fit: The Roborock Amazon listing explicitly names S8 Pro Ultra and describes the brushes as parts for mop washing and dock self-cleaning.
Replace when: Roborock recommends cleaning the dock maintenance brush as needed and replacing it every 6–12 months, or sooner if damaged.
Before buying: This small high-speed brush rotates in the dock's mop-washing tray; it is not either of the two floor rollers under the robot. Check the brush and holder against your dock part before ordering.

EXACT-MODEL FIT
What is shared, and what needs checking?
- S8 Pro Ultra vs. S8 and S8+
- S8 Pro Ultra is a distinct S8-series configuration with the Empty Wash Fill Dock and VibraRise 2.0. Check each component separately; the S8 Pro Ultra dual main-brush assembly is not the single full-width roller used by earlier Roborock models.
- S8 Pro Ultra vs. S8 Max Ultra and S8 MaxV Ultra
- These are separate robot models. A listing naming S8 Pro Ultra can support a specific shared consumable, such as the black side brushes or dock brush, but does not establish compatibility for filters, rollers or mop parts across all S8 models.
- Robot filter vs. dock water filter
- The washable white filter sits in the robot dustbin. The dock's water filter is a separate part that the manual says to remove and rinse as needed; it does not give a scheduled replacement interval.
- Robot rollers vs. dock cleaning brush
- The two main rollers underneath the robot pick up floor debris. The smaller high-speed brush in the Empty Wash Fill Dock cleans the mop in the washing tray. They are different parts.
- S8 Pro Ultra dock bags
- The listed six-pack is a 2.5 L disposable dust-bag pack that names S8 Pro Ultra. Confirm your dock model is EWFD07LRR or EWFD08LRR; a bag listing alone does not establish compatibility with another station.
CLEAN FIRST, REPLACE WHEN NEEDED
Roborock S8 Pro Ultra maintenance intervals
The manufacturer’s published care guidance for this model gives these intervals. Wear and your cleaning routine can change when a part needs replacement; follow the replacement manufacturer’s care instructions too.

|---|
| Washable robot-bin filter | Every 2 weeks | Every 6–12 months |
|---|
| Dual robot main brushes | Every 2 weeks | Every 6–12 months |
|---|
| Robot side brush | Monthly | Every 3–6 months |
|---|
| VibraRise 2.0 mop cloth | After each use | Every 3–6 months |
|---|
| Dock high-speed cleaning brush | As needed | Every 6–12 months |

|---|
Rinse the robot's washable filter with clean water and leave it to dry for at least 24 hours before reinstalling. Clear hair from both main-brush ends during routine cleaning. Keep a disposable bag installed when the dock auto-empties; rinse its separate water filter and clean the dock brush as needed.
Before you order
Which replacement filter fits the Roborock S8 Pro Ultra?
The linked original Roborock two-pack explicitly lists S8 Pro Ultra. Choose the white Filter-A option. It is the robot-bin air filter, not the dock water filter.

Which dust bags fit the Roborock S8 Pro Ultra dock?
