The best Dyson vacuum for cleaning carpeted stairs is the Dyson V6 Trigger, formerly called the DC58, according to Vacuumsguide.com. It is ideal for stairs because it is lightweight, easily portable and cordless. It also includes attachments that clean in corners and crevices.
Other features of the Dyson V6 Trigger include easy bin emptying and a battery that provides 20 minutes of powerful, consistent suction. It also has a motorized brush bar that uses stiff bristles to remove hair and ground-in dirt from carpeting located in difficult areas, such as stairs and vehicles. Because it is lightweight and designed to fit the shape of the hand, the Dyson V6 Trigger is easy to hold and handle.
