From Enozo to OzoJet: The Evolution of the Ozone Spray Cleaner
A spray bottle that makes its own cleaning solution from water sounds like a very new idea. Although it isn't, really.
The technology behind handheld ozone spray cleaners has been developing for well over a decade, with several companies taking very different approaches to the same basic challenge: how do you shrink ozone-water technology into something small, practical and easy enough to use like an ordinary spray bottle?
Some products reached commercial and institutional markets. Some made it into American homes. Some disappeared. Others evolved. Along the way, manufacturers experimented with different ozone-generation methods, water-conditioning systems, price points, batteries and service models.
Now a new generation is emerging.
More than 15 years of handheld ozone development
From early synthetic diamond electrode systems to today's replaceable ozone modules, the handheld ozone spray cleaner has gone through several distinct generations.
A Short Timeline of the Handheld Ozone Spray Cleaner
Key milestones in the category, arranged as an actual timeline rather than a table.

Next-generation development
Shanghai Xiyun Ozonetek begins development of the spray platform that would eventually become OzoJet™ in the Roving Blue U.S. market.
Inflection point
- March 2025: CPSC issues a safety warning covering a specific O3waterworks Home model because of a lithium-ion battery overheating hazard.
- 2025: Xiyun reports broader international sales of its new-generation ozone spray platform.
OzoJet™ enters the U.S.
Roving Blue begins a limited U.S. release of OzoJet™, introducing a handheld design with replaceable major components.
The story continues
Additional U.S. laboratory testing and product development continue as the category enters a new generation.
2010: The Enozo Story Begins Before There Was an Enozo
One of the important early companies in this history was originally called Electrolytic Ozone, Inc.
The company says it began taking shape in 2010 around the idea of using electrolytic ozone technology to replace conventional cleaning and sanitizing chemistries in commercial and household applications.
Traditional ozone-water systems were often relatively large pieces of equipment. Ozone could be generated from air or oxygen and then transferred into water through pumps, tubing and gas-dissolution equipment.
That works well in many industrial applications. It does not fit inside a spray bottle.
Electrolytic generation offered another possibility: produce ozone directly from water inside a compact electrochemical cell.
EOI worked with synthetic boron-doped diamond (BDD) electrode technology, and by 2013 the company was publicly discussing compact ozone-generation systems for applications that had previously been impractical.
2018: Tersano Shrinks Its Commercial Technology
Tersano followed a different path. The company dates back to 2002 and had already been developing larger systems that produced what it calls Stabilized Aqueous Ozone, or SAO®.
On March 16, 2018, Tersano formally introduced the iClean mini, describing it as a handheld device that converted ordinary tap water into an aqueous-ozone cleaning solution.
The iClean mini uses an electrolytic cell with a diamond electrode to generate ozone from water. Tersano paired it with a replaceable water-conditioning cartridge that reduces selected minerals before the water reaches the electrolytic cell.
2019: Enozo Reaches Documented Commercial Use
By 2019, the technology developed by Electrolytic Ozone had emerged under the Enozo Technologies name.
U.S. trademark records filed by Enozo Technologies identify May 2, 2019 as a first-use-in-commerce date for aqueous-ozone generators and spray bottles used for cleaning and sanitizing.
The Enozo system used a trigger-activated pump to move tap water through an electrolytic diamond cell, producing aqueous ozone immediately before it exited the spray nozzle.
Instead of creating an entire bottle of ozonated water and allowing the ozone concentration to begin declining while it sat in the reservoir, the system generated fresh ozone water during use.
Enozo also invested substantially in microbiological testing, including testing on hard, nonporous surfaces. That testing later became important documentation for both Enozo and O3waterworks.
2020: The Category Suddenly Comes Home
If there was a breakout year for consumer ozone spray cleaners in the United States, it was 2020.
O3waterworks launches nationally
On April 21, 2020, O3waterworks announced the U.S. consumer launch of its household aqueous-ozone spray bottle.
The product used technology manufactured by Enozo Technologies but was positioned directly toward ordinary households rather than primarily technical or professional buyers.
The timing was impossible to ignore. The launch came during the early months of the COVID-19 pandemic, when consumers were intensely focused on cleaning, surface treatment and alternatives to traditional products.
Later that year, O3waterworks publicized additional testing involving a human-coronavirus surrogate.
HoMedics drives the price downward
HoMedics also entered the category with the Ozone Clean Multipurpose Cleaner, SAN-OZ100.
Where earlier sophisticated aqueous-ozone equipment could cost hundreds of dollars, the HoMedics unit carried a $99.99 list price.
Its design was also different. Instead of generating ozone continuously during spraying, the HoMedics unit first generated a batch of ozonated water during a two- or four-minute cycle. The user then removed the bottle from its base and sprayed the prepared solution.
The category was already branching into different engineering approaches.
Tersano moves toward the household market
Tersano also returned to the consumer conversation in October 2020 with a home-oriented launch of the iClean mini.
The iClean mini combines an electrolytic diamond cell that generates ozone with a separate replaceable cartridge that conditions the incoming tap water.
By the end of 2020, the handheld aqueous-ozone category had something it had never really had before:
The First Generation Begins to Thin Out
Over the next several years, the consumer market changed.
The HoMedics ozone cleaner eventually became a discontinued product. O3waterworks' spray bottles later became difficult to obtain and are currently shown as sold out. Tersano continued with the iClean mini and its cartridge-based SAO system.
The category had clearly demonstrated that compact aqueous-ozone generation was technically possible. But it had also exposed some of the practical challenges of putting sophisticated electrochemical equipment into an everyday rechargeable appliance: cost, water quality, battery life, generator life and serviceability.
2024: Another Generation Begins
In 2024, Shanghai Xiyun Ozonetek began formal development of a new handheld ozone spray platform, according to information supplied by the manufacturer to Roving Blue.
Xiyun reports that international market activity followed in 2025, with units sold into multiple countries. Those sales figures are manufacturer-reported rather than independently audited.
The basic concept would have been familiar to engineers working on this category a decade earlier: put water into a handheld device, generate ozone electrolytically, and deliver freshly generated ozone water as a spray.
But some of the engineering priorities had changed.
2025: A Reminder That Serviceability Matters
On March 13, 2025, the U.S. Consumer Product Safety Commission warned consumers to stop using O3waterworks Home model SB100 HD spray bottles because the lithium-ion battery could overheat and create a fire hazard.
CPSC reported four overheating incidents and identified Enozo Technologies as the manufacturer.
The warning concerned that particular Home model. It was not a finding about every product Enozo or O3waterworks had ever made.
But it underscored something the next generation of small electrochemical appliances would have to confront:
The battery, electronics, water system and ability to repair or replace components also determine whether the appliance remains useful.
2026: OzoJet Enters the U.S. Market
Roving Blue began a limited U.S. release of OzoJet™ on August 13, 2026.
Like several earlier designs, OzoJet generates ozone electrolytically from water rather than requiring a cleaning concentrate to be added to the bottle.
But its service model is different from many earlier consumer appliances.
The rechargeable battery is replaceable. So is the ozone-generating module.
The manufacturer has confirmed an expected generator-module life of approximately 200 operating hours, after which the module can be replaced rather than discarding the entire appliance.
Roving Blue's first U.S. release was deliberately limited while retail packaging and broader commercialization were still being completed.
OzoJet also enters the market with something its predecessors helped make possible: more than a decade of lessons about what matters in a handheld ozone appliance.
What Has Actually Evolved?
Looking across the timeline, the evolution of the ozone spray cleaner is not simply a story about making more ozone.
The Story Isn't Finished
The handheld aqueous-ozone cleaner has already gone through several distinct eras.
Enozo helped develop and commercialize compact diamond-electrode ozone generation. Tersano brought its own diamond-electrode stabilized aqueous-ozone technology into a handheld format, coupled with cartridge-based water conditioning. O3waterworks pushed the concept into the U.S. household market. HoMedics demonstrated that a consumer ozone appliance could reach a much lower price point.
And newer systems such as OzoJet are beginning another cycle of development around serviceability, component replacement and additional efficacy documentation.
Roving Blue is currently commissioning additional U.S. laboratory testing of OzoJet as a spray-applied hard-surface system. As those results become available, this history will continue to be updated.
And we are very definitely still early in the story.
