This is Miele's newest, non-electric, telescoping wand and it is only for straight-suction canister Miele vacuums. This replacement wand will not work with models that take an electric power head, and will not work with any upright Miele models. Miele's new design eliminates the lock button and now has an easy slide lock design. Simply slid up or down to your desired length and it will lock in place. Genuine Miele Parts. Made in Germany
