This is a practical accessory for the Dyson V10 that also fits the V7 and V8 models. This accessory holder makes it easy to store all 5 parts at the base unit, even though the vacuum can only hold 2. The accessory includes a "Right", "Left" and "Offset" version so you have room for all your brushes and tools. An additional "Mattress" version has also been added for fitting the Mattress Tool.
