Evidence (1) — verified 2026-09-14

Filter, 3-Pack for Roomba 600 and 500 series — Official product explicitly covers both the 500 and 600 series.

Replacement AeroVac Bin (600 series)Unknown

iRobot's own AeroVac Bin page (SKU 4359682) gives an exact compatible-model list — 671, 676, 677, 692, 694 — and "635" is not on it, despite being sold on the "600 series" accessories page. Per this site's exact-list-over-series-name rule, we don't extend the claim just because "635" is a 600-series number. It may still fit, but that's not confirmed from this source.

Roomba 500 Series AeroVac Bin (White)Unknown

Downgraded per full not_compatible dataset audit: Live re-fetch of the cited SKU 21633 page found only "Compatible with Roomba 500 Series robots" -- a positive series statement that never mentions the 600 series, with no "only" wording and no physical/structural difference statement. A different official 600-series bin (SKU 4359682) existing isn't itself incompatibility evidence. May still be incompatible in practice -- just not confirmed from this source.
