## Questions owners ask

### How often should I replace the Roomba Max 775 Combo filter?

iRobot's 775 product page says to change the filter every 3 to 6 months. Its Max 700 Series care guide lists every 2 months, so heavy use or pets may call for the shorter end. The carbon filter 3 pack is $24.99 at the iRobot US store.

### Which bags fit the Roomba Max 775 Combo dock?

The Carbon AllergenLock debris bags (item 4861286, $24.99 for 3) list the Roomba Max 775 Combo Robot + AutoWash Dock as compatible. iRobot says the carbon bags keep homes fresh for about 3 months of hands off maintenance.

### Can I buy a replacement roller mop or battery for the 775?

As of October 16, 2026 the iRobot US store's roller mop (4849939) and Max combo battery (4850895) list only the Roomba Max 705 and 707 Combo, not the 775. Contact iRobot support before buying either for a 775.

### Are iRobot parts still available after the Picea sale?

iRobot was sold to Picea in January 2026 after Chapter 11, and iRobot says parts and support continue. The US store still lists bags, filters, edge brushes and a replenishment kit for the 775.
