The Tucker PRO High Flow 4-Stage RO/DI Cart (T-Cart-S4) is a mobile pure-water system built for professional window cleaners who want spot-free results without climbing ladders. It filters ordinary tap water through four stages into ultra-pure water, which rinses glass clean and dries with no spots or streaks - so technicians can clean from the ground with a water-fed pole instead of squeegeeing every pane by hand. An ultra high flow reverse osmosis membrane, available only from Tucker, produces more water than typical membranes, keeping the pole flowing on big jobs.
Where the T-Cart-S4 fits best
Pure water plus a water-fed pole changes how high and glass-heavy jobs get done. Crews use this cart to:
- Clean storefronts, office buildings, and multi-story glass safely from the ground.
- Wash solar panels without leaving mineral spots that cut efficiency.
- Service skylights, atriums, and other hard-to-reach glass that is dangerous to squeegee by hand.
- Clean fleets, RVs, and signage where a spot-free finish matters.
Because there is no squeegee and no detergent, water-fed pole work is faster, safer, and leaves a cleaner finish than traditional methods, and the cart's pure water reduces callbacks for spotting.

Frequently asked questions
What does a 4-stage RO/DI cart do?
It turns ordinary tap water into spot-free pure water for window and surface cleaning. Water passes through a sediment filter, a carbon filter, a reverse osmosis membrane, and a deionization resin, which strips out the dissolved minerals that leave spots when water dries.
Why does pure water clean glass without streaks?
Tap water contains dissolved minerals that dry into visible spots. Pure water has those minerals removed, so it rinses dirt away and evaporates without leaving residue - no squeegee or towel drying needed. That is what makes water-fed pole cleaning so fast.
How much water does the T-Cart-S4 produce?
At 60 PSI it produces about 1.5 gallons per minute with 70F water, and at 80 PSI it produces about 1.91 gallons per minute. The ultra high flow RO membrane is exclusive to Tucker and produces more water than typical membranes.
What are the four filter stages?
A 10-inch sediment pre-filter removes debris and rust, a 10-inch carbon pre-filter removes chlorine and chloramines, a 40-inch ultra high flow RO membrane removes dissolved solids, and a 10-inch refillable DI filter gives a final ultra-pure polish.
Is the cart easy to move around a job site?
Yes. It is built on a powder-coated lightweight steel frame with large no-flat tires, so a single technician can roll it across grass, gravel, and pavement without worrying about flats.
