If you search the Internet for ratings for vacuum cleaners, you will find a variety of websites and a variety of information. Other than our blog here, where can you find good info?
Of course, probably the best place to start is Consumer Reports. Consumer Reports should provide a pretty good review and ratings of vacuum cleaners from an unbias source.
Another good site is Consumer Search, that reviews hundreds of product reviews, analyzes them, distills the information shoppers need and recommends which products are the best. This site has a nice listing of vacuum reviews and ratings and breaks it into numerous settings:
Another interesting site is Consumer Democracy where consumers can list comments, links, etc on vacuum cleaners. You can see the vacuum cleaner section.
No matter what site you decide to do, you should spend some time reviewing ratings on vacuum cleaners when you decide to buy. If you ever have any questions, please feel free to post them here.
