Here is one more Dyson's product Dyson Root 6.
This little, lightweight vacuum cleaner, only 3.3 lbs with balanced weight distribution for easy handling, is made by advanced Cyclone™ technology, uses centrifugal force to spin dust out of the air. Recharges faster thanks to 21.6 volts lithium ion battery technology. Root 6, like all Dyson vacuum cleaners, hygienic and quick to empty (one-touch emptying and you don't need to touch the dirt). Has twice the suction of others in use, picks up crumbs and larger pieces.
Has combination accessory tools: nozzle converts to a brush tool for dusting and has an extra tool for cleaning in tight gaps and awkward spaces. The clear bin lets you see how well it’s working and when to empty.
Lifetime filters that never need to replace, just wash it six months. And of coarse this vacuum cleaner has 5 years warranty.
