The dust bag is made of melt-blown fabric and non-woven fabric, combined with the cleaning station to effectively capture 99.7% of ultra-fine dust down to 0.3 microns. It locks automatically when lifted, sealing the dust bag inlet to ensure dust and dirt remain inside. To maintain optimal robot performance, clean and replace parts as needed. For households with allergies or pets, it is recommended to replace the dust bag every 2–3 weeks. Large capacity design allows for more dust collection, reducing cleaning frequency. Simple and easy to replace—no special tools or professional skills required. Compatible with Henry Numatic Quick Models: Hen.100, NQ100, HET.100. Product weight: 30.5g. Dimensions: 12 x 12 x 19cm.
