The Roborock S9 MaxV Slim uses a low-profile chassis designed to navigate under furniture that standard-height S-series robots cannot reach, pairing that compact form with a retractable mop module and a single rubber brush in a tight housing. The slim body sits closer to the floor, which concentrates the airflow through a narrower path at each run: the robot still draws the full vacuum load through the filter and into the bin, depositing that material into the dock bag when the auto-empty station runs at the end of each session. The bag fills at a rate tied to daily household use rather than to suction tier alone; three to five weeks remains the practical replacement interval. The auto-empty dock draws debris into the bag after each session, clearing the bin automatically; a full bag stalls that transfer and leaves the robot with reduced bin capacity on the following run.
This ready kit of 18 Plus.Parts® compatible bags is matched to the S9 MaxV Slim auto-empty station. The bags are sized to the dock housing for a direct fit, sealing at extraction to keep debris and particles contained from removal through to disposal. With 18 bags per order, monthly changes are covered for well over a year from a single purchase without interim restocking.
The bags are built to the S9 MaxV Slim dock housing dimensions for a consistent install. Our team is available for any question about compatibility with your specific station or about your order.
