Roborock Q7

The Roborock accessories-catalog main-brush listing we cited explicitly names "Qrevo, Qrevo MaxV, Qrevo S, Qrevo Pro, Qrevo Plus, Q7 Max, and S7 MaxV" -- this model isn't literally on that list (a "+" variant, a plain Q7/Q7+, Qrevo Edge/Slim, or "S7 Max Ultra" which is a DIFFERENT model from the listed "S7 MaxV"). We'd been extending the claim via the Q7/Qrevo family grouping rather than the source's own exact wording. Downgraded; may well still fit, just not confirmed from this source.

Previously cited us.roborock.com/collections/accessories as "authorized_retailer_confirmed" evidence, but a live re-check of that page found no washable filter product covering this model at all -- the citation did not actually support the claim. Downgraded rather than leave an unfounded citation in place. A genuine Roborock-brand filter listing does exist for Q7 Max/Q7 Max+/Qrevo Slim (see those models), but not for this one specifically.

Live re-fetch of both official Roborock main brush listings (the DuoDivide listing linked from the Saros 10 product page, and the "standard" Qrevo/Q7-family listing at us.roborock.com/collections/accessories) found this exact model named only in neither official main brush listing at all (only "Q7 Max" is named in the "standard" listing, not bare "Q7"). Neither listing uses "only compatible with" or any exclusive wording, states a physical/mount difference, or explicitly excludes this model from the other listing -- a different official part existing isn't itself incompatibility evidence. Downgraded from not_compatible: absence from the DuoDivide listing isn't exclusion evidence.
