Cleaning Power

• Gentle Yet Effective: With wider spray nozzles (25° or 40°), it’s safe for car exteriors, windows, outdoor furniture, and painted surfaces without causing damage.
• Consistent Output: The Total Stop System (TSS) ensures the pump runs only when needed, maintaining steady pressure and conserving energy.
• Extra Soap Power: The 20 oz onboard detergent tank boosts cleaning effectiveness on greasy or heavily soiled areas.

Verdict on Cleaning Power: With 4,400 CU, the ePX3500 delivers a solid balance of muscle and control—perfect for most home cleaning tasks, though not intended for industrial-grade jobs.
