Downgraded per full not_compatible dataset audit: Live re-fetch of the cited SKU 4636450 page found "Compatible with select Roomba 500 and all Roomba 600 Series robots with an AeroVac Bin" -- a positive two-series statement, silent about the 700 series, with no "only" wording. Being unmentioned isn't exclusion evidence, even though a separate confirmed 700-series filter (SKU 4503461) also exists. May still be incompatible in practice -- just not confirmed from this source.
