DETAILING PRESSURE WASHERS
Power, Precision & Performance — The WashR Range
Step into the next era of car detailing with bigboi’s professional-grade pressure washers.
The right machine makes all the difference, and our WashRs are engineered specifically for detailing. With state-of-the-art features, cutting-edge design, and the iconic bigboi colour palette, these aren't just pressure washers — they're your upgrade to smarter, safer, more powerful detailing. Explore the range and find the perfect WashR for your setup.
bigboi Pressure Washers
When it comes to serious car care, nothing hits harder than a bigboi WashR. Engineered by detailers for detailers, our pressure washers deliver the perfect balance of high flow, controlled pressure, premium pumps, and ultra-quiet induction motors. Whether you're washing at home, running a weekend gig, or detailing full-time, bigboi has a WashR built around how you clean — not how a hardware store thinks you clean.
And unlike generic “one-size-fits-all” units, every bigboi WashR is designed specifically for automotive detailing, with the right PSI, the right LPM, and the flow you need for fast, safe, swirl-free washing.
Why bigboi Pressure Washers Are Different
Purpose-Built for Detailing
Where other brands chase big PSI numbers, we focus on what actually matters for cars:
Flow rate, pump quality, induction power, noise reduction, and expandability.
This means better foam, safer washing, and faster rinsing — without destroying paint, trims, or seals.
Premium Pumps & Induction Motors
Depending on your model, you’ll find:
- Commercial-grade Triplex pumps (PRO 20)
- German-designed wobble plates (DUO)
- Quiet-drive induction motors
- Long-life serviceable components
- Consistent pressure and high torque
This is the gear detailers trust when washing all day, every day.
Wall-Mount Ready, Garage-Friendly Designs
Most WashRs can be paired with bigboi’s wall-mount systems:
- Fast access
- Permanently plumbed setups
- Cleaner, more organised garages
- Better workflow for professionals
Plug in, pull out, wash. Too easy.
High Flow for Faster, Safer Cleaning
bigboi pressure washers are engineered around high GPM flow, giving you:
- Thicker, more stable foam
- Faster rinsing
- Better dirt lifting
- Reduced swirl-risk
- Less water wasted
This is why professional detailers don’t chase 3000+ PSI — they chase flow.
Choosing the Right bigboi WashR
Which Pressure Washer Should I Get?
For Home Users (FLO)
Perfect for washing your pride and joy on weekends.
Safe on paint, easy to use, plenty of power, and plug-and-play.
For Enthusiasts & Semi-Pros (DUO)
Higher flow, induction motor, and a German-designed wobble plate pump.
A noticeable upgrade if washing 1–5 cars per week.
For Professionals (PRO 20)
Our flagship unit — commercial Triplex pump, huge flow, whisper-quiet operation, and built for continuous use.
If you want the best of the best… this is it.
What PSI Do You Actually Need?
Cars don’t require extreme PSI. In fact, too much PSI increases the risk of damage.
Here’s the truth:
- 900–1400 PSI is perfect for vehicles
- Higher PSI is only beneficial for driveways, bricks, and heavy cleanup
- Flow (GPM) matters more for detailing than PSI ever will
This is exactly why bigboi units are engineered around high flow and balanced pressure, not inflated PSI numbers.
Gas vs Electric — Why bigboi Chooses Electric
Electric pressure washers offer:
- Lower noise
- Consistent pressure
- Better control
- Lower vibration
- Zero fumes inside a garage
Simply put: gas is overkill for detailing. Electric gives you precision, safety, and reliability.
What is the best pressure washer for car detailing?
The ideal pressure washer for car detailing offers a balance of safe PSI, high flow rate (LPM), and consistent performance. bigboi's WashR range is specifically designed for detailing, ensuring effective cleaning without damaging your vehicle's paintwork.
Can I mount my pressure washer to the wall?
Yes — the WashR QUAD, DUO, and PRO are all compatible with wall mounting. Pair them with our custom mounting solutions for a clean, space-saving setup that's ideal for home garages and professional detailing bays alike.
Can I use a foam cannon with bigboi WashRs?
Yes, all bigboi WashR models are compatible with foam cannons — and better yet, every unit comes with one included. This lets you lay down thick, clinging foam for a proper pre-wash and safer contact washing. Want to level up? Upgrade to our premium FoamR PRO+ Foam Cannon for maximum coverage and control.
Do you offer complete detailing kits?
Yes! Our Ultimate Garage Detailing Kits include everything you need for professional-level detailing — from pressure washers and blowers to vacuums, mounts, and premium detailing chemicals. It’s the all-in-one setup trusted by both home enthusiasts and pro detailers.
What maintenance is required for WashR pressure washers?
The WashR DUO and WashR PRO are fully serviceable, making them ideal for high-use setups and long-term performance. Routine maintenance includes checking hose connections, cleaning or replacing filters, and following the care instructions in the manual.
While the WashR FLO and WashR QUAD are not fully serviceable, some replacement parts are available to keep them running at their best.
What’s the ideal PSI and GPM for a detailing pressure washer?
For car detailing, a pressure washer with a PSI between 1200–1900 and a flow rate of 1.4–2.0 GPM is recommended. This range ensures effective cleaning without risking damage to your vehicle's paintwork.
What's better for detailing — high PSI or high flow (LPM)?
For car detailing, flow rate (LPM) is more important than max PSI. A higher flow helps rinse away dirt and chemicals more effectively without damaging the paint. That’s why bigboi WashRs prioritise flow with safe PSI ranges.
