The short answer: DETRAILERS systems run from about $6,995 for a budget-friendly entry-level setup up to $35,000+for a fully-loaded, enclosed, hot-water or multi-line hybrid system. Pricing is subject to change and depends on your exact configuration — this range is here to give you a real starting point, not a final number.
What actually drives the price
- Water tank capacity— more gallons means more jobs between refills, but more weight and cost.
- Hot vs. cold water— hot-water systems cost more but open up jobs cold water can't touch, especially for pressure washing.
- PSI and GPM— higher pressure and flow rate mean faster jobs, at a higher equipment cost.
- Open vs. enclosed— an enclosed trailer protects your equipment and your brand, but costs more than an open rig.
- Single-purpose vs. hybrid— combining pressure washing, soft washing and mobile vehicle wash on one rig costs more up front than any single system, but it's often less than buying two separate rigs.
The budget end (~$6,995)
An entry-level, cold-water, single-reel system is the most affordable way into the business, and it's a completely legitimate way to start and prove out your market before spending more. Our Economax is built specifically for this — the budget-friendly way to launch a mobile wash business. As a rule of thumb, banks generally won't finance equipment below about $6,000, which lines up almost exactly with where a real entry-level system starts.
The mid-range
Most operators land here: more tank capacity, hot water for pressure washing, or an enclosed trailer to protect equipment and look more professional on the job. Systems like the DB Series, DE Series, and DBP Series sit in this range, sized and configured to your budget.
The high end ($35,000+)
Fully-loaded systems — enclosed, hot water, larger tanks, multiple reels, or a custom multi-line hybrid that combines pressure washing, soft washing and mobile vehicle wash on a single rig — land at the top of the range. This is where a system stops being a starter rig and becomes a purpose-built, multi-service business on wheels.
Financing it
Most operators don't pay cash outright. Your own bank, an equipment credit card, or a home equity loan are all common ways to fund a system — see our financing options for specifics. And if your budget is tight right now, a modular system you can add to later is often the smarter move than stretching for capacity you don't need yet.

What's the cheapest way to start a mobile wash business?
A budget open-trailer, cold-water system with a single reel is the most affordable way in, and it's a legitimate way to start and prove out a market before spending more. As a rule of thumb, banks generally won't finance equipment below about $6,000, which lines up closely with where entry-level systems start.
Why do some wash trailers cost so much more than others?
The biggest cost drivers are water tank capacity, hot vs. cold water capability, PSI and GPM, whether it's open or enclosed, and whether it's a single-purpose system or a multi-line hybrid (pressure wash, soft wash and mobile vehicle wash combined on one rig).
