I purchased this last November at Edion, but I'm selling it because I bought a separate vacuum cleaner! One was used, so this is a set of two! iRobot Roomba AllergenLock Bags, Genuine, 2 bags [Brand] ・iRobot [Google AI Product Information] Brand: iRobot Product Name: Roomba AllergenLock Bags (Replacement Paper Bags) Contents: 3 bags per pack (※Only 2 bags for sale※) Features: These are paper bags specifically for the "Clean Base" automatic dirt disposal system. They prevent dust from scattering when emptying the dustbin. They use a special 4-layer high-performance filter that captures allergens such as pollen and mold. One paper bag can hold about 30 dustbin's worth of debris, up to a year's worth (depending on the home environment). Compatible Models: Compatible with Roomba i-series, j-series, and s-series models (e.g., i3+, i7+, j7+, s9+ etc.) that support Clean Base. Please confirm the compatible models at your own responsibility. The box will be folded and transferred to another box due to the thickness for packaging, so please understand. For those who understand personal management, thank you.
