Same Results, Better Price
Easy to handle, set up, and use. Very cheap for very high performance!
I love the Rhodi 0 Flow system. It’s easy to use, and I was able to get started quickly. The extra length on the brush hoses is fantastic, and the hose is more durable than the one on my last system.
The Rhodi 0 Flow is well priced, and I like the compact design. It helps us clean quickly, get good results and save money. The team and support have been incredible.
The Rhodi 0 Flow works great for me. I'm really happy with it.
I find the Rhodi 0 Flow easy to use and well built. It works as advertised, and I’m very happy with it.
What stood out was how easy and efficient the water-fed pole system was to use. It performed very well on my vehicle, making it easy to reach and clean hard-to-access areas while leaving a clean, spotless finish. Overall, I was very impressed with the performance.
Fits in my Mazda 3 hatchback perfect
I found the Rhodi 0 Flow easy to set up and get running. The instructions were clear and well written. I earned back what I spent on it in just two weeks.
It was able to purify the water very quickly and I did not have to wait very long.
Less effort!
The Rhodi Pro system has been awesome and does a great job and is easy to use. The system does a great job. Here in Indiana we have a lot of sediment in our water, coming off of spigot I was reading 296 ppm, coming out of the system was a 4 ppm.
But the customer service and follow up has been the best thing. Sending me messages asking how the system is working and if we’ve had any questions or issues shows they really do care about the quality of their products and their customers.
The RODI Pro is an awesome window-cleaning system! It makes the job faster and easier while leaving the glass crystal clear and streak-free. The results look incredibly professional—I highly recommend it!
⭐⭐⭐⭐⭐
We’ve been extremely impressed with the Rohdi Pro water-fed pole system! 💧🙌 The quality, ease of use, and overall performance have exceeded our expectations.
The system is lightweight, easy to set up, and makes window cleaning much more efficient. The water flow has been consistent, and it’s helped us work faster while still delivering excellent results for our customers. 🪟✨
What really stands out is the value. In our experience, it offers more for the money than other systems we’ve looked at, including XERO. 💪 If you’re looking for a professional-grade water-fed pole system without spending a fortune, Rohde Pro is definitely worth considering.
Huge thanks to the Rohde Pro team for putting together such a solid product. We can’t wait to keep using it long term. Highly recommended! 🚀💙

This Rhodi system works just as well as other brands but at a cheaper price. Also happy it fits in the backseat of my sedan car
The 0 flow system has been working great for us! We use two systems to clean around 10-15 houses a day. The pressure is great and reads 0 ppm all day every day. This is a great low cost entry system to use and you can make your money back in one day! Better yet, the team is awesome! They follow up quickly and ensure we are taken care of with every angle.
We've used the R/O Rhodi 0 Flow system for a few weeks now, completely on par with other R/O systems we have used at half the price.
Not only is it going to be more cost effective, we've been able to use two poles at the same time doubling our efficiency of spot free / streak free window.
This is my first WFP system and I’m so glad i invested in it.
To have Nick and his boys see how the industry was overcharging people and then come up with a system that does the same thing but at an affordable price is not only genius but a layup for guys like me who want to do right by our customers.
If and when I reach out, I know I will get a response.
I’m a fan because these guys backed up their promise and delivered.
I am one of the initial beta group of Rhodi users and I couldn’t be happier with the product or the customer service I’ve received. I started my window cleaning business five months ago after spending 30 years in Pharma… I’m not especially handy to say the very least. I received my Rhodi system on time and at the price I expected. I did have some initial issues which turned out to be operator error, but I was walked through the rectification process by Nick and the system is working perfectly… 0-1 TDS after approximately five cleanings. A side note… in a discussion with Nick he promised to take care of shipping for a replacement deionization cartridge. In my haste I ordered it and paid for it online including the two day shipping. Nick took the very proactive step of going in and crediting my account for that shipping which I was not expecting: I just wanted the system up and running as quickly as possible and so did he. I am convinced so far that this is a reputable company with an outstanding product at a great price, and I welcome any direct questions to discuss my experience. Sincerely, John McDonald H2OMG!

They were very responsive and helpful, responding to every email quickly!
Thank you, Keegan. We really appreciate the kind words and your support.
This is a great system. It's simple and straightforward. The cart itself is built very well and feels solid, especially the wheels.
It took me a little time to learn how to use the Rhodi 0 Flow, but other than that, it’s been perfect. I’m really happy with it so far.
I’m really happy with the Rhodi 0 Flow. The pole is light, super simple, and easy to use. It’s just as good if not better than other systems. I Love the price as well!
More productive days. Less ownership hassle. A professional system that makes sense for your business.
Rhodi delivers professional pure-water performance at a price that makes sense. Standard consumables, simple maintenance, and reliable support help keep both your upfront and long-term ownership costs under control.
LONG-TERM VALUE
A lower price shouldn’t mean sacrificing quality or performance. Rhodi delivers three-stage filtration on a durable, mobile cart with a powder-coated steel frame. Every system is quality checked before shipping and backed by a lifetime warranty on the frame and RO housing, plus reliable Rhodi support.
BUILT FOR PROFESSIONAL WORK
A higher price tag alone does not make water cleaner. Rhodi uses high quality sediment and carbon pre-filtration, reverse osmosis, and DI resin to get a 0 TDS output. We include all the filters needed. Pay for the filtration that does the work, without an inflated price.
THREE-STAGE RO/DI
Brand-locked filters and cartridges can leave you paying one supplier's price for years. Rhodi uses standard replacement filters and accessible housings, so you can choose compatible parts from Rhodi or another supplier. Stay in control of maintenance costs and source what you need to keep working.
NON-PROPRIETARY FILTERS
Your Rhodi arrives fully assembled with all filters, sealed DI resin, a TDS meter, filter wrenches, waste-water hose, and operation manual included. Load the resin, connect your hoses, then use the meter to verify your output. No complicated assembly or specialized tools required. You can begin producing pure water in minutes.
EASIER TO OWN
Moving ladders from window to window eats into your day. Pair Rhodi with a compatible water-fed pole to clean upper-story exterior windows from the ground, reduce ladder use, and move through jobs more efficiently. Less time repositioning means more time cleaning and more room for paying jobs.
WORK FROM THE GROUND
Three filtration stages work together to turn ordinary tap water into pure water for professional window cleaning. Carbon and sediment pre-filtration protect the membrane, reverse osmosis removes dissolved solids, and DI resin polishes the output to a 0 TDS target.
Maintenance should fit your route. The Rhodi 0 Flow uses standard replacement filters instead of brand-locked cartridges, with accessible housings for straightforward changes.
Source compatible replacements through Rhodi or your preferred supplier.
Flow depends on feed-water pressure, temperature, TDS, and operating conditions. Maximum output may require a properly sized booster pump. Check the included TDS meter to confirm water quality.

RO means reverse osmosis, which removes dissolved solids from the feed water. DI means deionization: a resin stage that polishes the remaining water to the system’s 0 TDS target. Use the included TDS meter to check your output.
Yes. The Rhodi 0 Flow creates pure water; your water-fed pole delivers it to the brush and glass. If you already own compatible equipment, buy the system on its own. You can also add a pole and accessories from the options on this page.
The system ships fully assembled, with the carbon/sediment pre-filter and RO membrane installed. The DI resin is sealed separately and must be loaded before use. Connect your feed-water and outlet hoses, follow the start-up and flush instructions, and verify the output with the TDS meter.
The system uses standard garden-hose connections. Check your pole hose and adapters for a compatible connection before ordering. Contact Rhodi if you would like help checking your setup.
Filter life depends on your feed-water quality and usage. Monitor output with the included TDS meter and follow the current maintenance instructions for your filters, RO membrane, and DI resin.
The limited lifetime warranty covers the housing and frame for the original purchaser against defects under normal use. Factory-installed non-consumable parts and workmanship carry 12 months of coverage. Filters, membranes, resin, and other consumables are excluded. See the full warranty policy for terms.
The return window is 30 days from delivery for unused items in their original condition and packaging. Equipment that has been exposed to water is not eligible under the standard return policy. Return shipping is the customer’s responsibility. Read the returns and exchanges policy before ordering.
