Description
At bigboi, we understand that achieving the perfect wash requires the perfect combination of PSI and water flow rate. Thats why weve fine-tuned every aspect of the WASHR PRO, from the pump head to the motor, hose kit, and nozzle orifice, creating the ultimate professional washer kit. Built with the latest cutting-edge technology typically found in machines over $1500 AUD, the bigboi WASHR PRO is equipped with a Total Stop System (TSS) that senses water flow in the pump and automatically turns off when the trigger is released, reducing noise and motor wear.
The WASHR PRO features Brushless Induction Technology, providing it with four times the lifespan of conventional washers. Its commercial duty Italian-designed Triplex forged brass pump head and 4-pole setup deliver low 1450RPM with high torque, making it one of the quietest units with a noise level under 80DB. The WASHR PROs commercial-grade construction is backed by a standard 2-year warranty and an impressive 10-year limited warranty on the pump head.
With a maximum rating of 1850PSI (130BAR) and a flow rate of 9.5LPM (2.5GPM), the WASHR PRO outputs a tuned rate of 1450PSI with a water flow rate of 9.2LPM, ensuring efficient cleaning.

WashR PRO Set FAQ’s
Whats the difference between the original WashR PRO and the MKII?
Based on valuable feedback from our customers, we have upgraded the WashR PRO to the MKII. The MKII features a new operating system that no longer relies on a PCB board, addressing a common issue faced by our mobile detailers. The original unit was sensitive to incorrect extension leads, excessive distances, or inconsistent power, which could affect performance. The MKII resolves these issues, making it more robust and reliable for commercial use.
Weve also had the new units field-tested by professional detailers all around Australia, receiving great feedback on its improved reliability and performance.
Can I use an extension cord?
Yes you can – just make sure it is a Heavy Duty, 10A plug. You need heavy gauge conductors rto reduce voltage drops. As an example check out the HPM 10m 1.5mm 10A 3 Core Extra Heavy Duty Tradesman Extension Lead from bunnings.
