TrackDrive 

Will stay on track 
The Boost CX1 bagless vacuum cleaner from Miele follows obediently on the heels of its user thanks to TrackDrive. Wheels on the sides of the appliance lend it stability and direction. This protects both furniture and door frames from damage. What’s more, it can be manoeuvred with ease and convenience – for outstanding vacuuming results without compromise.
