Yeedi k781+ – Plus.Parts® Replacement Dust Bags

The Yeedi k781+ is Yeedi’s mid-range robot vacuum bundled with a self-emptying station, the version of the k781 that removes daily bin emptying from the user’s routine. After each cleaning session, the station’s motor creates a strong suction pulse that clears the robot’s onboard bin into a larger sealed bag inside the dock. The k781’s bin is compact by design, sized to keep the robot’s profile low for under-furniture access; the self-emptying station is what makes this practical for regular use rather than a manual emptying step after every run. The system is straightforward and reliable, but it depends on the dock bag being in good condition and not overfull. As the bag fills, the suction available for the transfer pulse decreases, and once the bag reaches capacity, the transfer stops working effectively. The robot’s bin begins to carry residue from one session into the next, reducing available capacity and gradually trimming what the k781+ picks up in each run. Keeping the bags replaced on schedule keeps the auto-empty system doing its job.

This set contains three Plus.Parts® replacement dust bags for the Yeedi k781+ self-emptying station. Each bag is sized for the dock’s compartment, seals at removal to contain debris and allergens, and is made with filtration material that maintains airflow and particle retention through the bag’s full fill cycle.

The filtration media is selected to hold fine particles during the high-speed suction transfer, keeping them in the bag rather than allowing them back into the room air. Questions about which bag fits your k781+ dock? The team responds personally.
