Pack of 10 dust bags for vacuum cleaners i7/i7+/S9/S9+/i3/i3+/i4, dust bag extractor holder

100% perfect fit. The dust bag is compatible with iRobot Roomba i7 / i7+ (i7556) / i3 / i3+ (i3552) S9 / S9+ / i4 robot vacuums. Suitable for all models with a self-cleaning base station, ideal as an iRobot Roomba bag replacement. High-quality materials. The dust bag consists of two layers of fine fiber filter layers and two layers of non-woven fabric to ensure high-efficiency filtration and capture 99% of dust and dirt, effectively preventing secondary pollution. The high-density fabric ensures the dust bag is extremely durable and won't be punctured by sharp debris inside. Additionally, there's an on/off door that prevents dust and pollen from escaping. Great design. The sliding door design features a robust seal, ensuring that the collected fine dust is fully contained within the vacuum cleaner bag. For allergy sufferers, this means relief from allergenic fine dust particles in the indoor air, promoting a healthier lifestyle. We recommend changing the bag every 2-3 months. This ensures the vacuum cleaner's cleaning efficiency and reduces the release of dust, pollen, and other allergens into the air. Please note that vacuum cleaner manufacturers' brand names are used only to demonstrate compatibility.
