Maximise the performance of your Miele vacuum cleaner by using official Miele HyClean 3D Efficiency dustbags. The first to market random-spun bag with 3D effect, this dustbag will allow you to vacuum for up to 20 percent longer before it needs replacing. The new generation of dustbags offer the highest level of efficiency when vacuuming at low power levels; this allows you to save energy when vacuuming without compromising the high cleaning performance you are used to. Using Miele dustbags with your Miele vacuum cleaner will form a perfect lock-and-key principle which results in vacuumed dust being directed securely into the dustbag. This means that you can breathe easier whilst doing the chores, as dust re-emissions are vastly reduced.
