Spring loaded vacuum cleaner nozzle

摘要

A vacuum cleaner of the fixed or floating nozzle type wherein a spring is utilized for urging the suction nozzle into the carpet pile to maintain and improve nozzle suction over a wide range of carpet pile heights and types. Such cleaners often lose nozzle suction as the pile height of the carpet increases and forces the suction nozzle upward away from the carpet. The addition of a spring to force the suction nozzle downward restores and improves nozzle suction and thereby improves overall cleaning efficiency of the vacuum cleaner.
