If you're running crews on residential routes or apartment complexes, the biggest softwash headache isn't the cleaning — it's the setup. Trailers don't fit everywhere. Skids are overkill for a 20-unit walkthrough. And letting employees hand-mix SH is how you end up replacing siding. The ProTool Clever is a portable softwash unit that solves all three problems: it fits in the back of a car, doses chemicals automatically, and runs off tap water with no pump.

Why Portable Softwash Units Matter for Crew Operations

Tim Carver of Fish Window Cleaning has been running the Clever on crew vehicles for several years: "I love that the Clever can easily be placed in the back of my employees' larger cars. It's perfect for residential jobs and apartment complexes. Plus I don't have to worry about chemicals being mixed wrong. My employees can just set the dial and know the mix is going to be correct. Set it and forget it."

That's the operational point most contractors miss when evaluating softwash equipment. The question isn't just flow rate or PSI — it's whether you can deploy the system without a CDL, without a trailer hitch, and without babysitting every mix. A portable softwash unit that doses proportionally eliminates the most expensive variable in crew work: human error on chemical ratios.

How the Clever Doses and Delivers

The Clever is designed around 12.5% sodium hypochlorite and a surfactant like ProTool Sticky, but it handles any liquid or soluble concentrate you load into the tote. You carry your chemical at full strength — no pre-mixing in the field.

Setup is three steps: connect a garden hose for water supply, load your chemical tote, and turn the metering dial to your target ratio. The proportional injector draws from the tote and blends in the mixing chamber at a constant ratio regardless of flow fluctuation. Output is 3.5–4 GPM from standard tap pressure — no pump, no battery, no generator.

The unit ships with a wand and tip set, but swaps easily to your own lance or softwash WFP adapter. Add whatever length of delivery hose your jobs need and it rolls.

Key Features of This Portable Softwash Unit

• Proportional dosing — the injector maintains a precise, constant chemical ratio at any flow rate. No over- or under-dosing, no guesswork.
• No pump required — runs entirely off municipal or well tap pressure, delivering 3.5–4 GPM. No battery, no motor, no maintenance on moving parts.
• SH-capable construction — built to handle 12.5% sodium hypochlorite and compatible with most liquid concentrates contractors use.
• Externally adjustable — change your mix ratio on the fly without stopping flow or opening the tote.
• Fits any vehicle — compact enough for the back of an SUV, a van, or a truck bed. No trailer needed.

When the Clever Makes More Sense Than a Skid

A full 12V softwash skid is the right tool for high-volume commercial work — multi-story buildings, large HOA contracts, fleet operations where you're pulling from a 50+ gallon batch tank all day. But most residential and light-commercial contractors don't need that capacity on every truck.

The Clever fills the gap: jobs where you need consistent softwash delivery without the weight, cost, or vehicle commitment of a skid-mounted system. It's especially effective for operators adding softwash as a service line who aren't ready to dedicate a truck to it, or for multi-crew companies that need a portable softwash unit on every vehicle without multiplying equipment costs.

For replacement parts and accessories, J.Racenstein stocks the full line — mixing chambers, suction valves, draw tubes, bypass switches, and tote caps — so field repairs are same-day, not wait-for-the-manufacturer.
