Safety first: Use gloves and ensure good ventilation when using cleaning chemicals.

• Clean gasket: Wipe the Roborock door gasket thoroughly with a cloth soaked in a mixture of water and mild bleach or a washer cleaner. Pay attention to folds where water collects.
• Run cleaning cycle: Run an empty hot wash (90°C if available) with a washer cleaner or white vinegar to flush the tub.
• Leave door open: After each use, leave the door and detergent drawer slightly open to allow drying.
• Check drain filter: Clean the drain pump filter to remove trapped debris that can cause odors.
