Beam has added an electronic user-information panel to the Serenity IQS central vacuum system's list of features. A vivid blue LCD screen monitors the 640-air-watt system's cleaning efficiency, the amount of dirt in the collection tank, and service needs. As an added perk, it also delivers up-to-the-minute time and temperature updates. Beam Industries, 800.369.2326; www.beam.com.
