1. Which cleaning tasks must the accessories cover?
Start with the workload, not with the tool catalogue. The Cleaning Equipment Series page positions the driving-style PWD02 for indoor garages and narrow outdoor parking spaces, where a single operator walks around a vehicle instead of driving it into a fixed box. Write down what one shift actually covers: exterior bodywork, wheels and sills, engine compartment, or interior upholstery and floors. The machine ships with a high-pressure water gun with nozzle for the steam and hot-water work, plus a vacuum cleaner with a flat nozzle that feeds a sewage tank. Anything outside those two tool sets needs a separate accessory decision.
2. Does the gun need lance extensions or angled attachments?
A standard gun reaches flat panels comfortably. Underbody rails, wheel wells and door sills usually demand an extension lance; interior corners, seat runners and vents usually demand a narrower or angled nozzle. Ask the supplier which attachment lengths and spray patterns are offered, and whether they connect to the fitting already fitted to the gun. Buying tools with the wrong connection turns a useful option into dead stock.
3. Are steam and water tools interchangeable on the same wand?
The PWD02 offers three working modes — dry steam, wet steam and hot water — and each mode behaves differently on a surface. Dry steam is the low-moisture setting for degreasing and for areas where you do not want standing water; wet steam and hot water carry more volume and do the flushing. Confirm whether one wand and one set of nozzles can be used across all three modes, or whether mode changes require a different tool. This single answer changes how many items the operator has to store in the bay.
4. How long are the hoses, and is that length enough for one bay?
Because the unit is a driving-style mobile device that can be stopped and driven at any time, hose length is often less critical than in a fixed installation — but it is not irrelevant. Measure the distance from the parking position to the farthest point of a typical vehicle, then compare it with the hose and cable lengths quoted by the supplier. Published specification sheets for the PWD02 list machine dimensions (L1275 mm × W570 mm × H1185 mm), a 60 L clean water tank and 4.5 kW of semiconductor heating power, but they do not publish hose, wand or cable lengths. Treat those as open questions in your enquiry, not as settled numbers.
5. Which consumables are needed from day one?
Microfibre cloths, interior brushes, wheel brushes, foam pads and sealant bags are cheap individually and expensive when a bay runs out mid-shift. Ask the supplier to price a starter consumables package in the same order, and to state which parts are wear items with a replacement interval. A spare nozzle set in the cupboard costs far less than one stopped line of vehicles.
6. Is the configuration battery-powered or mains-supplied?
PowerDe lists the PWD02 in two variants: a version without battery and a version including battery. The specification table records 220 V working voltage with a replaceable mobile battery option. That choice drives the accessory list: a battery variant needs a defined charging arrangement and a spares plan, while a mains variant needs cable routing that survives wet, vehicle traffic. Match the accessory order to the variant you actually buy.
7. What protection and service items come with the machine?
The product description states leakage protection, short-circuit protection, high-temperature protection, high-voltage protection, water-shortage protection and high-voltage explosion-proof design. Use these names as a checklist when you ask for spare parts and for the filter, seal and nozzle items that a wet, hot environment wears out. Also ask which items are stocked locally and what the lead time is, since a machine sitting idle while a $20 fitting ships is the most expensive accessory of all.
8. Can the supplier adapt the package to your site?
Shenzhen PowerDe Automation Precision Equipment Co., Ltd presents customised configurations and technical support alongside its equipment lines, and its Solutions pages are aimed at buyers with a defined duty cycle rather than a catalogue SKU. Send your bay layout, the vehicle types you wash and the modes you expect to use most, then ask for an accessory list built around that profile.
A short enquiry checklist
- Tasks: exterior, wheels and sills, engine compartment, interior — which of these run every day?
- Tools: extension lances, angled nozzles, spray patterns, and the fitting standard of the existing gun
- Modes: can the same wand serve dry steam, wet steam and hot water?
- Lengths: hose, wand and cable — ask, because the published table does not list them
- Power: battery variant or 220 V mains, plus charging or cable plan
- Spares: nozzles, seals, filters, wear items, stock location and lead time
- Warranty and commissioning: what is included, what is charged separately
Answer those seven questions and the accessory list writes itself. If you want a package matched to your site instead of a generic catalogue, contact PowerDe at sales@powerde.net or call +86 13023198376.
