The Samsung VC21F50UKGC is a 2100w Vacuum Cleaner with extreme suction power which works with the extreme force brush. The extreme force brush distributes pressure evenly over the brush whilst being able to work on any surface to clean with ease picking up dirt and dust particles as well as delivering outstanding results. With the CycloneForce it has a centrifugal force that will separate the dirt and debris and place it into an outer chamber helping it to maintain its suction whilst also keeping the filter clear. It also has built-in control buttons on a remote control handle (2 xAAA batteries Not Supplied).There is also an easy to empty & Clean Dustbin. Thanks to the unique Air Cushion Protector design of the Samsung VC21F50UKGC the soft curved bumper will stop any unsightly scratches, dents and marks that can accidentally happen. Another feature is a dust sensor which will light red if it identifies a dust patch and then changes green when it becomes clean.
