How It Works
Three purification stages take your tap water down to a pure 0 TDS, with dual RO for higher output.
Carbon + Sediment Pre-Filter
Tap water enters through a standard garden hose and passes through a carbon and sediment pre-filter that removes dirt, chlorine, and particulates before they can reach and damage the RO membranes.
Dual RO Membranes
Two commercial RO membranes work in parallel, stripping out the majority of dissolved solids while producing roughly twice the output of a single-membrane system.
DI Resin Polish
The deionization stage polishes the water the rest of the way to a pure 0 TDS. That spot-free water feeds your pole and dries without a squeegee.

Rhodi Output vs. Inlet Pressure
Expected product flow at each inlet pressure. Every extra 10 PSI adds roughly 0.32 gal/min.

Built for Higher-Demand Work
More output, stronger rinsing, and the reach to handle bigger jobs.
Twice the Output
Dual RO membranes produce roughly double the pure water of a single-membrane system, so your filtration never becomes the bottleneck on a demanding job.
Ready to Run
Arrives fully assembled and pre-plumbed. Connect your feed and pure water lines, flush the membranes, and start producing pure water.
No Proprietary Parts
Standard-sized filters and membranes. Buy replacements from Rhodi or any water-filtration supplier. No vendor lock-in.
Reach and Rinse
Designed to support water-fed pole work at roughly 30 to 40 feet or higher, with stronger rinsing through longer hose runs.

Maintenance Guide
Keep your dual RO system running at peak output.
How often should I replace the carbon and sediment pre-filter?
Replace it after about 5,000 gallons, every two months, or sooner if flow drops or the filter looks contaminated. Protecting the RO membranes from chlorine and sediment is the key to long membrane life.
When do the RO membranes need attention?
Membrane life depends on water quality, chlorine exposure, and operating pressure. Test your source-water TDS and RO-output TDS periodically. A steady drop in rejection or production after proper flushing means the membranes need cleaning or replacement.
How do I know when the DI resin is exhausted?
Watch the TDS meter on the output. For professional window cleaning, replace or refresh the resin before output climbs past 10 ppm. Resin life depends heavily on your input water hardness.
Do I need to flush the membranes?
Yes. Flush the RO membranes before and after use as directed. Regular flushing clears concentrated dissolved solids and supports membrane performance and longevity.
How should I store it in freezing conditions?
Never let water inside the system freeze. Drain the housings, membranes, and tubing, and for long storage follow the membrane-preservation procedure with an RO storage solution. Keep it out of direct sunlight.
Frequently Asked Questions
When does the Rhodi 00 Flow ship?
The Double O Flow is scheduled to become available in October 2026. Pre-order customers are reserved from the first production run and fulfilled in the order received. The October window is an estimate and can shift with manufacturing, freight, or customs timing.
How does the pre-order work?
Reserve your system now with a fully refundable $100 deposit and lock in 30 percent off plus free shipping. The remaining balance is due October 1, 2026, before your unit ships.
How is the 00 Flow different from the 0 Flow?
The 00 Flow runs two commercial RO membranes instead of one, producing roughly twice the pure water under the same conditions. It is built for cleaners running larger properties, longer hose runs, and taller work where a single membrane becomes the bottleneck.
How much water does it actually produce?
Output depends on your inlet pressure, water temperature, input TDS, hose length, and membrane condition. At typical city water pressure of 40 to 80 PSI it produces roughly 1.3 to 2.5 gallons of pure water per minute. See the output chart above for the full range.
Do I need a booster pump?
Not usually. More output does not remove the need for adequate incoming pressure, so in low-pressure conditions, very long hose runs, or high-reach work, a compatible booster pump may be recommended to reach full production.
Are the filters and membranes proprietary?
No. The 00 Flow uses standard-sized filters and membranes. Buy replacements from Rhodi or any qualified water-filtration supplier. You are never locked into a single source or overpriced cartridges.

Frequently Added Together
Most customers pick up at least one of these before their first job.
Do I need a water-fed pole to use this system?
Yes. The Rhodi 0 Flow produces pure water, but you need a water-fed pole to deliver it to the glass. Without a pole, you have no way to apply the water at height. The Rhodi UP and UP CORE are designed to work directly with this system.
Why do I need a dedicated pure water hose?
Your standard garden hose is fine for feed water coming in, but you need a separate pure water hose for the output line running to your pole. Mixing up the two or using a low-quality hose on the output side can introduce contamination and raise your TDS readings.
What does a rinse bar actually do?
A rinse bar attaches to your brush and adds a second row of jets that rinse the frame and glass as you work. It reduces the number of passes needed on each window and speeds up your cleaning time on larger jobs.
Can I use my existing brush with this system?
You can, as long as it accepts standard fittings. If you are starting from scratch or want the best results, the brushes in the Rhodi lineup are matched to the flow rate of this system and are sized for common residential and commercial work.
