FAQ sur WashR
General Pressure Washer Questions
Can I use an extension lead with my bigboi WashR?
Yes, but you must use the correct extension lead for your model.
For WashR PRO, WashR TRADIE, WashR DUO, and WashR QUAD, use an extra heavy-duty extension lead no longer than 15m. Heavy-gauge conductors are required to reduce voltage drop and help protect the unit.
For WashR FLO, use a heavy-duty 10A extension lead with heavy-gauge conductors.
Important: Using an incorrect extension lead, a lightweight cable, or a lead longer than recommended may cause voltage drop, damage the electronics, affect performance, and may void your warranty. The same applies when using a generator.
Can I use a generator with my bigboi WashR?
Yes, selected WashR models can be used with a generator, but the generator must be able to supply stable, consistent power.
Undersized or unstable generators can cause voltage drops, performance issues, or damage to the unit.
| Model | Generator Guidance |
|---|---|
| WashR PRO | Use a generator capable of producing 4000 watts. |
| WashR TRADIE | Use a generator capable of producing 4000 watts. |
| WashR DUO | Use a generator capable of producing 3500 watts. |
| WashR QUAD | Use a generator capable of producing 2500 watts continuous power. |
| WashR FLO | Contact bigboi before use, as the unit may need to be modified for generator use. |
Can I use my WashR with a power board?
No. WashR PRO and WashR TRADIE must be plugged directly into their own wall outlet or an approved heavy-duty extension lead.
Power boards can cause power instability, performance issues, or damage to the machine, and may void your warranty.
How does the Total Stop System benefit the user?
The Total Stop System, or TSS, senses water flow through the pump and automatically stops the unit when the trigger is released.
This helps reduce noise, lower motor wear, prevent unnecessary heat build-up, and extend the life of the machine.
Can I use a bigboi WashR with water from a bucket or tank?
This depends on the model.
Most bigboi WashR pressure washers must be connected to a pressurised mains water supply. They are not designed to draw water from buckets or tanks, as inconsistent water flow can reduce performance, strain the pump, and may void your warranty.
For best performance and product life, always follow the water supply requirements for your specific model.
| Model | Bucket or Tank Use |
|---|---|
| WashR PRO | No. The WashR PRO must be connected to a pressurised mains water supply. |
| WashR TRADIE | No. The WashR TRADIE must be connected to a pressurised mains water supply. |
| WashR DUO | No. The WashR DUO must be connected to a pressurised mains water supply. |
| WashR QUAD | No. The WashR QUAD must be connected to a pressurised mains water supply. |
| WashR FLO | Yes. The WashR FLO is self-priming and can be used with water from a bucket or tank. |

Where do I get replacement washer oil?
Applicable WashR pressure washers use non-detergent pump oil.
We recommend a high-quality non-detergent oil rated API SF, SG, SH, SJ or higher. You can use SAE 10W-30 or 15W-40, depending on your climate and operating temperature.
Change the oil after the first 30 hours of use, then every 100 hours after that.
Tip: Never use automotive or detergent oils, as they can damage the pump over time.

The result is a more robust and reliable unit, especially for commercial and mobile detailing use. The MKII has also been field-tested by professional detailers around Australia, with strong feedback on reliability and performance.

Is the WashR QUAD suitable for professional use?
The WashR QUAD is a strong choice for enthusiasts and light professional use, offering professional-style performance in an affordable and lightweight form factor.
However, it is not serviceable and may not be ideal for long periods of heavy commercial use. For full-time professional detailing, the WashR PRO or WashR TRADIE is the better choice.
Why is my WashR QUAD taking longer to build pressure?
If your WashR QUAD is taking longer than usual to build pressure, check whether the hose is running up a slope, hill, or stairs.
Elevation changes can cause pressure to take longer to stabilise. For best performance, keep the hose positioned on a flat surface where possible.
If the issue continues, contact bigboi support for further assistance.
