Introducing the new & improved bigboi WASHR PRO MKII, a professional-grade pressure washer designed for the fussiest detailers. Equipped with advanced technology, including a Total Stop System (TSS), Brushless Induction Technology, and a commercial duty Italian designed Triplex forged brass pump head, this washer delivers a perfect combination of PSI and water flow rate. With a maximum pressure of 1850PSI and a flow rate of 9.5LPM, the WASHR PRO ensures an efficient and quiet operation, making it an indispensable tool for professional car care.
At bigboi, we understand that achieving the perfect wash requires the perfect combination of PSI and water flow rate. That’s why we’ve 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 PRO’s 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. The washer also includes ¼ inch quick connect attachments all around and is designed with the iconic bigboi colour palette.
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.
We’ve 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 1.5mm² 10A 3 Core Extra Heavy Duty Tradesman Extension Lead from bunnings.

"I purchased this to replace a faulty previous pressure washer and my expectations have been exceeded. This is by far the best pressure washer I’ve ever used."
"Nick and his Team are second to none. I ordered some products and decided to pick them up from the store and was left feeling more confident in my choices and selections. During the first intial meeting nick and i started talking about the pressure washers and equipment and was run through every detail i needed. Will be coming back time and time again."
"This unit is absolutely worth the hype. I'm not a detailer, just an enthusiast, but the flow rate and PSI strike the perfect balance. And the noise level? Next level. My young son usually runs away when I fire up a pressure washer because of how loud they are. But with this one, it's so quiet that the sound of the water hitting the car is louder than the machine itself. He had a blast using this with me to wash my car, with the adjustable pressure on the pump heling to reduce pressure for him! Well done, Bigboi."
