ProTeam 103243 Sierra Backpack Vacuum Cleaner Review
The ProTeam 103243 Sierra Backpack Vacuum Cleaner is manufactured by veteran professional appliance company ProTeam. It is a commercial-grade vacuum that is built with an unparalleled four level filtration system. Not only does it clean carpet, but it also uses a microfilter to filter out dust, microbes, allergens, and other harmful material from the air, all without disturbing and stirring up dust. The result is a thoroughly clean carpet and a friendlier breathing environment. You’ll also see a noticeable absence of odors after a few uses. 
The ProTeam Sierra is effective on carpet, but its excellent suction power also makes it effective on hardwood floors, tile and linoleum. The vacuum is a light-weight at only ten pounds, and its backpack design makes it easy to maneuver difficult and tight spaces. This makes it a favorite in hotels and other facilities where frequent, thorough cleaning is a necessity. This vacuum is also quiet, with an operational noise level of only 68 decibels. Its versatile design also allows you to use it as a canister. As an additional convenience, it also includes a tool belt to keep necessary items within reach.
The ProTeam 103243 Sierra Backpack Cleaner retails at about $414.00, and is well worth the price. This vacuum uses a replaceable bag system, and the bags must be purchased separately.
