Vacuum cleaner having a dual filter assembly

摘要

A vacuum cleaner (10) having a dual filter assembly (26) includes a filter cage (32), a primary filter (28) disposed on the filter cage (32), and a secondary filter (30) disposed downstream of the primary filter (28). A float valve (64;52;62) between the primary filter (28) and the secondary filter (30) inhibits liquid from coming into contact with the secondary filter (30).
