Aqueous ozone is produced by our unique on-board, on demand system will clean hard floors during daily use, reducing the harmful bacteria that can build up on hard floors & in the scrubber itself. Our Zer03 unit produces the aqueous ozone on demand so there is no chance of degradation or dilution of the product as with other systems. If deeper cleaning or floor preparation is required the operator can switch to the Suds system which will inject chemical from a reservoir at a preset dilution into the water that feeds the scrub deck.
