Battery charger cradle 

Vacuum for longer with the battery charger cradle 
The battery charger cradle and a spare battery help to double the running time of your Miele vacuum cleaner. You can continue charging the appliance while vacuuming at the same time: charging is independent of operation. With the Miele Triflex HX2 Pro vacuum cleaner, the handy battery charger cradle and spare battery are always included.
