What to know before buying

Listing details to confirm

The listing is inconsistent about capacity: the details specify 2.5 Liters, while feature copy claims 3.2L. It also names Roborock C10 in one compatibility field despite otherwise listing Eufy C10 and C20 Omni. Confirm bag capacity and the intended vacuum model before ordering. The claimed 99.97% filtration is a manufacturer claim, not an independently verified result.
