Dreame RDB3 Replacement Dust Bags 3-Pack for L10s Ultra, L10 Ultra, L20 Ultra, L20 Ultra Complete – 3L Capacity, Self-Sealing, High-Efficiency Filtration

Robot vacuums with auto-empty docks are only as good as their dust bags—and a full or torn bag means dust, pet hair, and allergens escape back into your home. The Dreame RDB3 replacement dust bags are engineered specifically for Dreame L10s Ultra, L10 Ultra, L20 Ultra, and L20 Ultra Complete models, ensuring a perfect fit and reliable seal every time. Each bag holds up to 3 liters of debris, so you empty less often and keep your robot running at peak performance.

Tips

Replace the dust bag every 4–8 weeks depending on usage. If you have pets or high-traffic areas, check the bag more frequently and replace when it feels full or the dock's suction seems reduced. Always keep a spare pack on hand to avoid downtime. Dispose of used bags in household waste—do not attempt to wash or reuse.
