Define the service before the equipment
Equipment should follow a written process. Decide whether the first offer is maintenance washing, interiors, full details or a combination. That determines water use, extraction, chemical range, working time and the price the setup has to support.
- Write the steps for one exterior and one interior service
- Record expected minutes and consumables at each step
- Remove any machine that does not shorten or improve a paid process
The minimum working chain
A reliable setup needs supply, delivery, recovery and storage. For exterior work that normally means a water source, suitable hose, pressure or rinse method and safe chemical storage. Interior work needs dry debris removal, agitation, controlled moisture and drying—not necessarily an extractor on day one.
- Water: source, connector, hose and shut-off
- Power: customer outlet, generator or battery system with compatible loads
- Vehicle: restrained storage, spill control and enough remaining payload
Buy in dependency order
Choose the vehicle constraints and service process first. Then size water and power. Only after that should you choose machines, because their flow, electrical load and physical dimensions decide what else must fit.
- Confirm payload and usable dimensions
- Model water use and simultaneous watts
- Shortlist equipment by specification, warranty and service support
- Price the job with labour and consumables included
Compare the workable approaches
| Approach | Best for | Check before buying | Main trade-off |
|---|---|---|---|
| Lean starter kit | Testing demand or working from a car | Customer water and power permission | Lower independence and more setup at each job |
| Working mobile setup | Regular weekly bookings | Backup water, hose reach and power plan | More storage and payload pressure |
| Self-contained rig | Sites without reliable utilities | Full-tank payload and simultaneous load | Highest cost, weight and maintenance |
