Roborock Saros Z70

Page last built: 2026-09-14

Worth knowing"TriCut" is NOT Roborock's official name for this brush — it's aftermarket-seller branding. The real official name, confirmed directly on Roborock's own US product page, is the "FreeFlow™ Main Brush" (part of the Dual Anti-Tangle System). We initially missed this on a first pass and incorrectly said Roborock used no special name at all — corrected. Also, "Saros Z70 Ultra" — a model name that appears in many third-party parts listings — could not be confirmed on Roborock's official site; we're not treating it as a real, distinct model until we find an official source.

Models in this series may share some parts, but compatibility must be verified for each part individually — this page groups them for browsing only. Where an exact per-part verification exists, the model below links to it.

Do not assume these fit: despite similar names, Saros 10, S9 MaxV Ultra, Saros 10R, Saros 20 use different parts and are NOT covered by this page.
