Roborock Qrevo

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 the "standard" main brush listing (bare "Qrevo"). 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.
