The Carpet and Rug Institute (CRI) has developed the Seal of Approval program to measure cleaning effectiveness of vacuums and other cleaning systems. Tested in an independent laboratory, each product is put through a series of scientific, measurable tests. Those that perform well enough earn platinum, gold, silver and bronze medallions. For a list of the highest-rated products, visit CRI’s website ( and search Seal of Approval. In no time, you’ll find a vacuum cleaner that’s right for you.
