Quick answer
The CELLONIC 2800mAh battery fits both Klarstein R290 and several iRobot Roomba models including the 960, 760, and 780, but not all Roomba models are compatible.
What makes the CELLONIC battery compatible with multiple brands
The CELLONIC 2800mAh battery is designed as a drop-in replacement for robot vacuums that share similar battery connectors and voltage requirements. This means one battery can serve both Klarstein and select iRobot models, simplifying your replacement search.
Limitations you need to know
Not every Roomba model uses the same battery shape or connector. For example, Roomba 600-series models like the 605 and 620 are listed as compatible, but newer models like the Roomba e5 or i7 series use different batteries. Always verify your specific model number before ordering.
