Before ordering this part
First read the complete model code on your machine and the number 155FFJ on the listing. With power disconnected, compare the original head or roll, connection points, and the complete machine code. A motorized head, loose roller, and above-floor tool are separate components even when they share a model list. If the label differs from the published list, treat the fit as unverified and ask Shark support.
