The NII Hot Skid 21LPM 12V is a fully self-contained, van-mounted commercial pressure washing system combining a Honda GX390 21LPM pressure washer with a 12V Mazzoni Hotbox for cold water, hot water and steam cleaning.
The key advantage of this system is that no external electrical power supply or separate generator is required. A dedicated alternator is fitted to the Honda GX390 engine, supplying the power required to operate the 12V Mazzoni Hotbox.
Simply start the GX390 and the system is ready to work — making it an ideal setup for mobile commercial cleaning.
Mounted alongside a 460-litre baffled water tank within our custom laser-welded aluminium frame, this is a complete professional pressure washing system designed and built for everyday commercial use.
Purchase your NII Hot Skid directly through our website and we'll include a FREE Turbo Lance with your system.
Unlike a traditional 240V hot-water pressure washing system, the NII 12V Hot Skid does not require mains electricity or a separate generator to operate the hotbox.
We fit a high-output alternator directly to the Honda GX390 engine, which supplies the electrical power required by the 12V Mazzoni Hotbox.
This means the complete system can operate solely from the GX390 engine, giving you a cleaner, simpler and more compact setup inside your van.
Start the engine. Turn on the hotbox. Get to work.
The 12V Mazzoni Hotbox gives professional cleaners the flexibility to carry out standard cold-water pressure washing as well as hot-water and steam cleaning.
Ideal for tackling:
We can professionally fit and install the complete system into your van, giving you a secure, tidy and ready-to-work commercial pressure washing setup.
If you require installation, we recommend calling our office before purchasing so fitting can be added to your order and we can discuss your van and installation requirements.

The biggest advantage is simple:
No mains power. No separate generator. No additional power supply.
The Honda GX390 powers the pressure washer and the fitted alternator supplies the electrical power for the 12V Mazzoni Hotbox, creating one complete self-contained hot and cold pressure washing system.
For mobile operators, this means less equipment in the van, quicker setup on site and no reliance on the customer's electrical supply.
Designed, built and assembled by NII Clean Products, the NII 12V Hot Skid is made for professional cleaners who want a fully self-contained cold, hot and steam cleaning system without the need for an external electrical power supply.
Fully Self-Contained, No Mains Power Required.
Made in the UK & Northern Ireland, Reliable Quality.
