DESC: Reviewers top-rate this Hoover more often than any other full-sized canister vacuum on the market. It offers powerful suction and good edge-cleaning ability. Experts especially like the WindTunnel's nozzle design, which helps prevent dirt from being "spit" back out of the machine. Although this vac doesn't offer HEPA filtration (recommended by most allergists for allergy and asthma sufferers), it performed very well in emissions tests.
