The part number is what identifies the right part
Roborock spare parts are identified by codes in the 9.01.xxxx format. The code is usually printed on the part itself, on its packaging or on the service report. If the code on your old part, or the one given by a service centre, is 9.01.3498, this is the same part. If you cannot read the code, do not choose by appearance or by the device name alone; confirm the code with a service partner before fitting.
