Roborock S80ULT – Plus.Parts® Spare Dust Bags

Roborock’s S80ULT belongs to the S8 Ultra family, Roborock’s top-spec tier, combining high suction output with a comprehensive auto-empty dock that handles debris collection, mop washing, and water refilling without requiring manual steps between sessions. The dock keeps the robot ready to clean again on schedule, and the dust collection bag at the heart of the debris loop is the one part of that system that needs regular replacement. Every time the robot returns from a run, the dock’s evacuation motor pulls the collected debris into the bag. Over a week of daily cleaning in a typical home, the bag accumulates a significant volume. At full capacity, the bag needs to be swapped: the dock’s suction cannot compress debris into a full bag any further, and the robot’s dustbin will not empty as completely on each docking. For a robot at this level of specification, keeping the collection system in good condition is a straightforward part of protecting the investment.

This set of four Plus.Parts® spare bags is designed as a direct-fit alternative to the original Roborock collection bags for the S80ULT dock. The collar matches the dock holder’s profile and the bag body fits within the chamber at the proper depth. Four bags per order is sufficient for several months of typical use, and having spares on hand means each bag change is a one-minute task with no wait for a replacement to arrive.

The bag material seals at the neck for contained removal and traps fine particles at the inner surface during use. Our team is reachable for any question about compatibility with your S80ULT dock or delivery of your order; we answer directly.
