The root cylone technology is one of the patented features of the dyson vacuum dc33. This feature keeps the suction of the vacuum cleaner strong even for years to come. This feature deserves to be patented so that no one else can copy this innovation made by the engineers of dyson.
Besides the root cyclone technology, the dyson dc33 vacuum cleaner comes with accessories to make cleaning much easier. It has a crevice tool for cleaning tight gaps in the house and it also has the soft dusting brush for cleaning delicate types of floor.
Another accessory of the dyson dc33 vacuum cleaner is its telescope reach wand that can extend up to 15.7 feet. With this accessory, you can clean hard to reach areas of the house like walls and stairs.
You can be assured that the patented features of the dyson dc33 will last. This is guaranteed by Dyson as shown by its five year warranty on labor and parts.
