Buy Irobot Roomba 780 -

Because the 780 is an older model, finding it brand new at major retailers is rare. You can typically find it through these channels:

: If you already own one, official sites like iRobot Support still provide information on compatible parts, and specialty shops like iRobotof list accessories like brushes and filters.

: Websites like eBay and local marketplaces like Avito are the most common sources for pre-owned or refurbished units.
