Designed with optimum dust retention in mind, Miele have created the HyClean Dustbag with 3D efficiency. The bag side-folds ensure the whole of the bag is inflated when in use. This equates to an additional 20 per cent more than the previous design. Miele deliver performance and build quality to the finest detail. The vacuum cleaner filtration system is no exception to this. With a three stage filtration process built into the body of each vacuum cleaner, dust, allergens and odours are captured and contained, leaving your home clean and free of dirt. Miele have created a special fleece that provides nine layers of filtration that retain more fine dust and small particles then a conventional Dustbag. Also featured is the auto-shut mechanism that automatically closes the bag when the vacuum cleaner is opened, preventing dust from escaping back into the air.
