Compatibility varies by part. Being in the same series does not mean every part is shared — check each part below individually.

Common compatibility traps:
  • S8 MaxV Ultra and S8 look similar, but Edgewise Mop Cloth (hot-water-wash) is compatible for S8 MaxV Ultra while it's unknown for S8.
  • S8 MaxV Ultra and S8 look similar, but Sonic Mop Pad (standard) is unknown for S8 MaxV Ultra while it's compatible for S8.

FlexiArm Design Side Brush

Unknown
FlexiArm functionality does not establish a distinct replacement brush. Previously compatible (manufacturer_confirmed) on the strength of Roborock's support article (https://support.roborock.com/hc/en-us/articles/33954114436761-What-is-the-difference-among-of-S8-Pro-Ultra-S8-Max-Ultra-and-S8-MaxV-Ultra), which only says S8 Max Ultra and S8 MaxV Ultra "are equipped with the FlexiArm Design Side Brush" — a feature difference, not a statement about which replacement brush fits. No official FlexiArm-specific replacement brush product was found, and Roborock's standard side brush (SKU RR-BS5-Q85MaxPlus-M2) names S8 Max Ultra and S8 MaxV Ultra directly. Whether this is a real separate part is under audit.

Sonic Mop Pad (standard)

Unknown
No source states this standard mop cloth does not fit. Previously not_compatible (manufacturer_confirmed) on Roborock's support article (https://support.roborock.com/hc/en-us/articles/33954114436761-What-is-the-difference-among-of-S8-Pro-Ultra-S8-Max-Ultra-and-S8-MaxV-Ultra), which only lists "Edgewise Mop Cloth" among S8 Max/MaxV Ultra features — and the Edgewise cloth is the side (rotating) mop's cloth, not a replacement for the main mop. Roborock sells a dedicated main mop cloth for these models (SKU RR-KJTB2-S8MaxVUltra-P02), and this standard product (RR-TB2-S7MaxV-02) does not list them, which suggests a different main cloth but is not an explicit exclusion.
