Dreame RDB3 dust bag, for L10, L10s, L20 and L30 Ultra

The Dreame RDB3 is a dust bag for the L30 Ultra, L20 Ultra, L10s Ultra, L10s Prime, L10 Prime and L10 Ultra robot vacuums. It collects the dust and debris the robot picks up, and when it is full you fit a new one. A full bag makes cleaning less effective, so it is handy to keep a spare.
