SRX Rainbow systems
Current-generation Rainbow systems where the motor unit, separator, basin, hose, power nozzle, and attachments need coordinated checks.
Rainbow / Rexair Vacuum Repair
Rainbow systems from Rexair use water-based filtration, a separator, hoses, wands, power nozzles, tanks, and attachments rather than a standard bag or bin. Diagnosis should separate airflow, water-basin setup, separator condition, hose or wand power, and power-nozzle brush behavior before replacing major parts.
Repair frequency grade
B
Lower repair frequency
Rainbow repairs are usually high-value diagnostics involving motors, separators, basins, hoses, power nozzles, switches, cords, and attachment systems.
Grade reflects non-routine repair frequency, with A as the best grade for lower-frequency repair issues and F for the highest-frequency repair issues; routine bags, filters, and tuneups are not counted. Rexair has manufactured Rainbow systems for decades, supports manuals and distributor-based service, and the machines are expensive enough that targeted repair often makes sense.
Popular Rainbow / Rexair model families
E2 and e SERIES systems
Popular Rainbow generations where hose power, wand contacts, power nozzle operation, water-basin condition, and motor sound are key clues.
D4C, SE, D3, and legacy Rainbow models
Older Rexair machines where repair value depends on motor condition, seals, cords, switch parts, basin fit, and attachment availability.
Power Nozzle, AquaMate, and attachments
Accessory systems where brush-roll operation, belts, hose/wand electrical contacts, tanks, valves, and solution paths may be separate from the main unit.

Repair questions
Rainbow / Rexair repair notes
Why does a Rainbow diagnosis focus on the separator and water basin?
Rainbow systems depend on correct water-basin setup, clean separator airflow, seals, and attachment paths, so those checks come before assuming a major motor failure.
Can the Rainbow power nozzle fail while suction still works?
Yes. The main unit can still have suction while the power nozzle has a belt, brush roll, wand contact, hose electrical, or nozzle-motor issue.
Are older Rainbow or Rexair models still repair candidates?
Often, yes. Older D-series and E-series machines can be worth evaluating when the motor, basin, hose, power nozzle, and available parts are in practical condition.
