The Dyson Root 6 is a battery-powered, rechargeable handheld vaccum touted as the vacuum that doesn't lose suction. It doesn't because of its filterless design, that eliminates dirt build up. It features the RootCyclone technology and a quick charge time. One of its key features is that it can be emptied with a push of a button - meaning no one needs to handle any dirt.
It is a fairly powerful handheld vacuum with 21.6 Volts of power from its rechargeable Lithium Ion battery. However, expect to only get about 5 - 6 minutes of continuous use before requiring a recharge. Dyson claims that the Root 6 charges three times faster than its competition (no references of charge time could be found). It is a fairly heavy handheld vacuum, weighing 3.3 pounds. There have been conflicting reviews on the weight balance of the Root 6 and its easy-of-use.
The Dyson Root 6 was released in October 2006 and retails for around $150. If you are not impressed with the style of the Root 6, see the Dirt Devil Kurv.
