Regular maintenance is required for the iRobot Roomba s9+, including cleaning the filter, brushes, and CleanBase, and replacing the filter every 2 months, but replacement components are widely available and the vacuum has a self-cleaning dock and Smart Recharge and Resume feature.
The iRobot Roomba s9+ requires regular maintenance, including cleaning the filter once a week (twice if you have pets) and replacing it every 2 months. The brushes and CleanBase also need to be cleaned regularly to keep the vacuum in good order. Replacement components for the s9+ are widely available and easy to replace.
The dustbin automatically empties into the self-cleaning dock after each cleaning session, and the disposable bag can hold the debris collected by Roomba during 30 cleaning sessions. The charging dock has no specific maintenance requirements mentioned. The rechargeable battery is not user-replaceable, but the Smart Recharge and Resume feature allows the vacuum to automatically return to the charging dock when the battery is low and resume cleaning where it left off once the battery is recharged.
The frequency of maintenance depends on the size of the home and the amount of debris on the floors.
