Meet the new Guardian XP™ GXP-WST
For years, the Unitec Wash Select 2 was one of the most recognizable automatic wash entry systems in the car wash industry. Thousands of operators relied on its simple interface, dependable performance, and familiar footprint to manage customer transactions at automatic wash bays.
But times have changed.
Following industry acquisitions and shifting product strategies, support for the Wash Select 2 has become increasingly limited. As existing units age, operators are faced with a difficult question:
What is the best replacement for a Wash Select 2 pay station?
At Standard Change-Makers, we believe the answer shouldn’t require expensive touchscreens, complicated software subscriptions, or a complete site redesign.
That’s why we developed the Guardian XP™ GXP-WST.
A Direct Replacement for Aging Wash Select 2 Units
The GXP-WST was specifically engineered to fit within the same footprint as the Wash Select 2, allowing operators to upgrade aging equipment without major modifications to their site.
Instead of replacing concrete pads, redesigning entry lanes, or investing in expensive custom installations, operators can replace an obsolete unit with a modern platform designed around simplicity, reliability, and affordability.
For operators looking to control costs while modernizing their wash entrance, the GXP-WST offers a practical path forward.
Why We Didn’t Build Another Touchscreen
Many new pay stations entering the market today are built around large touchscreens.
While touchscreens can be visually appealing, they also introduce challenges:
- Higher replacement costs
- Increased maintenance requirements
- Greater exposure to vandalism
- Reduced visibility in direct sunlight
- More expensive field service calls
The Guardian XP GXP-WST takes a different approach.
Instead of relying on a touchscreen, customers interact through rugged illuminated metal selection buttons, a durable metal keypad, and a sunlight-resistant LCD display.
The result is a user experience that is straightforward, dependable, and easy for customers to understand – just like the Wash Select 2.
More importantly, it helps operators reduce long-term ownership costs.
Compatible with Leading Credit Card Processing Systems
Payment flexibility is critical in today’s car wash environment.
The GXP-WST is compatible with several of the industry’s most popular credit card and mobile payment platforms, including:
- Nayax
- Cryptopay
- Monex
- Cantaloupe ePort
This gives operators the freedom to select the processing solution that best fits their business model, rather than being locked into a single payment ecosystem.
Customers can pay with cash, cards, mobile payments, or promotional codes, depending on the site configuration.
Marketing Tools Built Into the Machine
A wash entry system should do more than collect payments.
It should help operators grow revenue.
The Guardian XP platform includes a powerful suite of built-in promotional tools that can be programmed directly into the machine:
- Time-of-Day pricing
- Day-of-Week discounts
- Promotional discount codes
- Charity fundraising codes
- One-Time-Use codes
- Discount token programs
These features allow operators to drive traffic during slower periods, support community events, reward customers, and create targeted promotions without requiring expensive third-party software.
Designed for Real-World Operators
The GXP-WST includes features operators actually use every day:
- Painted or Stainless Steel Cabinet options
- CPI T7-Talos bill validator
- SlugBuster III electronic coin acceptor
- Four illuminated wash selection buttons
- Sunlight-resistant LCD display
- Industrial metal keypad
- LED accent lighting
- Voice prompt activation through proximity sensing
- Integrated cooling fan
- 2,000-coin hopper capacity for quarters, dollar coins, or tokens
Every component was selected with durability and serviceability in mind.
Another Option for Hamilton ACW Owners
Operators running older Hamilton ACW installations should also consider the original Guardian XP™ (GXP).
The GXP was specifically designed to be retrofitted into older Hamilton ACW cabinets after the original equipment is removed. This allows operators to modernize payment acceptance while reusing existing site infrastructure.
Like the GXP-WST, the GXP provides access to the same promotional tools, payment flexibility, and proven Guardian XP platform.
The Bottom Line
Not every car wash needs a complex touchscreen kiosk.
Many operators simply want a reliable, affordable wash entry system that customers can understand, technicians can service, and owners can depend on for years to come.
The Guardian XP GXP-WST was designed with that philosophy in mind.
If you’re searching for a replacement for an aging Wash Select 2, the Guardian XP GXP-WST delivers modern payment flexibility, powerful promotional tools, and a familiar footprint—all without the cost and complexity of today’s touchscreen-heavy alternatives.
