A lean operator can start with a used cargo van or pickup, a pressure-washing skid, water tank, hose reels, containment berms, wet vacuum, basic filtration, hand tools, personal protective equipment, and a small chemical inventory. A more automated operator may use a specialized tunnel or batch system. Alliance Manufacturing, for example, describes a machine-controlled shopping cart sanitizing system for high-volume stores, while commercial pressure-washing suppliers list individual washers, skids, and trailer systems from a few thousand dollars into the mid-$20,000 range. Those vendor prices are useful anchors, but the founder still needs to budget for water recovery, vehicle capacity, installation, insurance, and working capital.
Planning assumptions in the table are intended for a one-vehicle U.S. operation. Current supplier listings show examples such as $2,099-$4,450 pressure-washer units, $6,000-plus skids, and a roughly $25,985 trailer package on a commercial pressure-washing equipment catalog. Quotes, freight, installation, taxes, and regional vehicle prices will differ.
The SBA startup-cost framework is useful here because it separates one-time purchases from monthly expenses and opening cash. That cash reserve is not optional: retailers may pay on net-30 or net-45 terms, while technicians, fuel vendors, and insurers must be paid sooner.
