1. A system for delivering alternating pulses of high and low pressure fluid to a target comprising:
- a spray nozzle having a high pressure inlet, a low pressure inlet, and an outlet for directing a fluid stream;
a high pressure fluid supply line having a control valve therein for interrupting high pressure fluid flow therethrough, said high pressure fluid supply line connected to the high pressure inlet of said spray nozzle; and
a low pressure fluid supply line having a check valve therein to prevent reverse-fluid flow, said low pressure fluid supply line connected to the low pressure inlet of said spray nozzle.

Abstract
The present invention provides a system (10) for cleaning and sanitizing surfaces that incorporates a high pressure fluid supply (52) and a low pressure fluid supply (42), often carrying an ozonated fluid, and alternates directed streams of the two fluids for application to contaminated surfaces through a single applicator (70, 100).
