The cited page's title/scope is "Roomba Cleaning Head for Roomba 500, 600 & 700 series" -- a positive three-series statement that never mentions the s9 line at all. No "only" wording or explicit s9 exclusion appears on the actual page. May still be incompatible in practice -- just not confirmed from this source.
