Benefits of an All-In-One System
Improved Efficiencies
lotus PRO V9 creates SAO on-site and on demand, eliminating the need to purchase, store, and manage multiple cleaning products. By replacing multiple chemicals with one solution, SAO streamlines cleaning processes.
Cleaner, Healthier Spaces
Leaving no toxic residues behind that can reattract dirt and grime, SAO helps keep surfaces clean for longer. With no added toxins or fragrances, SAO supports cleaner, healthier spaces and is dermatologically approved for sensitive skin.

Patented Technology.
Proven Science.
The lotus PRO creates SAO on demand by safely infusing tap water with ozone that has been stabilized to extend usability. SAO acts as a powerful oxidizer that breaks down soils and inactivates microorganisms*, then reverts to water and oxygen without leaving chemical residues.
The system connects to cold tap water.
The cold tap water enters the cartridge, removing select minerals to maximize ozone's longevity.
The lotus PRO V9 dispenser safely infuses the water with ozone.
A simple on/off switch controls the flow of SAO.
A series of indicator lights communicate the system's status in real time.
The desiccant filter removes moisture from the air and tracks the cartridge's cycles.
The lotus PRO V9 plugs into a standard electrical outlet.
The ready-to-use SAO solution dispenses into spray bottles, mop buckets, and floor scrubbers from the yellow nozzle.

Frequently Asked Questions
The lotus PRO V9 is an on-site cleaning system that converts tap water into Stabilized Aqueous Ozone (SAO®) for daily cleaning tasks, replacing multiple traditional chemicals.
SAO is water infused with ozone that has been stabilized to extend its usability. It acts as a powerful oxidizer that helps break down soils and contaminants, leaving no harmful residues.
Aqueous ozone (AO) is ozone dissolved in water that typically dissipates quickly. SAO is engineered to remain stable for up to 24 hours for disinfecting* and up to 6 days for cleaning, allowing it to be stored and used over longer periods.
On-site generation means the cleaning solution is produced at the point of use from tap water, eliminating the need to purchase, transport, and store conventional chemicals.
SAO works through oxidation. The ozone reacts with organic matter, breaking down dirt, grease, and contaminants into simpler, harmless substances.
Ozone gas and aqueous ozone have very different safety profiles. Ozone dissolved in water at controlled levels—such as SAO—is widely approved and used in cleaning applications as a safer alternative to traditional chemicals.
SAO appears as a clear liquid and has a very light, fresh scent that dissipates quickly. It does not contain the harsh or toxic artificial fragrances typically associated with conventional cleaners.
The system is utilized by facility managers, cleaning professionals, food service providers, educational institutions, corporate offices, and organizations that seek to reduce chemical use while maintaining high cleaning performance. Major lotus PRO users include ISS, Sodexo, McDonald’s, Google, Microsoft, Intel, Stanford University, and more.
While nearly every industry can benefit from the lotus PRO, common applications include healthcare, education, hospitality, food service, commercial real estate, and industrial facilities—any environment focused on cleaning efficiency and sustainability.
Using IoT technology, the lotus PRO V9 transmits usage data to the iClean Dashboard, a digital platform that enables managers to track system usage in real time, monitor cartridge life, and download ready-made sustainability reports to simplify ESG reporting.
Unlike traditional systems that rely on multiple chemicals, the lotus PRO produces a single, versatile solution on-site, reducing chemical handling, storage, and operational complexity. With no toxic chemicals, SAO provides a safer, healthier environment for staff and guests while helping reduce plastic waste and chemical pollution.
The lotus PRO and SAO reduce reliance on packaged chemicals, lowering plastic waste and minimizing transportation-related emissions by generating a cleaning solution on-site and on demand. Unlike many traditional cleaning chemicals that persist in the environment, SAO is 100% biodegradable, reverting to water and oxygen after use.
The lotus PRO and SAO replace up to 90% of everyday cleaning chemicals, reducing purchasing costs, lowering inventory management needs, and simplifying training and operations.
The lotus PRO and SAO streamline operations by consolidating multiple cleaning products into a single solution, reducing training requirements, minimizing usage errors, and decreasing storage needs. The system dispenses SAO ready-to-use, reducing the need for measuring, mixing, or batching chemicals.
