Claims20
A surface cleaning apparatus comprising:
- a housing adapted to be moved across a surface to be cleaned;
- a fluid distribution system provided with the housing for storing and supplying a fluid, and comprising a supply tank from which a portion of the fluid is provided;
- a cleaning pad mounted to the housing and in fluid communication with the fluid distribution system;
- and
- a reactive oxygen species generator provided with the housing in fluid communication with the supply tank, the reactive oxygen species generator comprising:
- a transducer;
- and
- an acoustic horn operably coupling the transducer to the portion of the fluid;
- wherein the acoustic horn transfers energy to the portion of the fluid to generate reactive oxygen species which are provided to the cleaning pad.
A method of generating reactive oxygen species on-board a surface cleaning apparatus having a housing with a cleaning pad attached to the housing, the method comprising:
- ultrasonically cavitating a fluid containing water molecules to generate reactive oxygen species;
- and
- providing the generated reactive oxygen species to the cleaning pad.
