Fits. Shark explicitly names RV750 on the 1171FK870 supported-model list. Preserve the _N or regional suffix; the record does not automatically cover a similarly numbered model without that suffix.
The attachment point matters more than the number of arms. Check whether the brush uses a screw or a push-fit hub, the shape of its center and the manufacturer's part identifier. Three-arm and five-arm brushes can look interchangeable while belonging to different drive modules. Keep any module-version caveat on the official listing with the fit decision.
With the robot powered down, inspect the user-removable brush for wrapped hair, damaged arms and a cracked hub. Use the removal method in the model manual. A push-fit brush must seat normally; a screw-fit brush should not require a substituted screw or extra force. A brush that still stalls after cleaning needs further manufacturer diagnosis rather than repeated replacement purchases.
An aftermarket seller may describe a longer bristle or softer material as an upgrade. Those descriptions do not establish fit or measured cleaning performance. Compare the mounting method and complete model list with the source below.

Questions about Shark ION RV750
Does a listed original part verify an aftermarket pack?
No. Match that pack separately. The original identifier, source market and any model suffix must agree, and seller-only wording remains unverified.
Why can the page show an excluded or unverified item?
Those records explain a known mismatch or an evidence gap. They help prevent an incorrect purchase; neither state has a shopping button.
