Our pressure washer range spans from a R809 replacement hose to a 2,500L diesel-braked jetting trailer at over R100,000 — so “which pressure washer” really breaks down into three separate decisions: power source, pressure rating, and whether you need a trailer at all.
Petrol, diesel or electric?
Electric units (2.2kW, 220V) are the simplest option where you’ve got reliable power on site — workshop yards, fixed wash bays. No fuel to manage, lower noise, less maintenance.
Petrol units free you from a power point and are common on our mobile trailer models, typically running 186-248 bar. Good middle ground on upfront cost and portability.
Diesel units dominate the higher end of our range — 10hp diesel engines pushing 241 bar, often with electric start. Diesel suits sites already running diesel plant (farms, fleets, construction), and generally handles continuous heavy-duty use better than petrol over a long working day.
Reading the bar rating
Our stock ranges roughly 100-248 bar. As a rule of thumb: 100 bar units suit lighter routine washdown (vehicles, yard equipment); 186 bar covers most general industrial cleaning; 241-248 bar is jetting-grade pressure for stubborn build-up, drain jetting, and heavy equipment. Higher bar isn’t automatically “better” for every job — it’s more aggressive, so match it to what you’re actually cleaning rather than defaulting to the top of the range.
Trailer-mounted vs mobile unit vs trolley
If the washer needs to travel between sites behind a vehicle, our trailer units (500L-2,500L integrated water tanks) mean you’re never dependent on an on-site water source. Smaller jobs are better served by our mobile skid units (1000L) or 210L trolley units, which are easier to manoeuvre around a single yard or workshop without needing to be towed.
Braked vs unbraked trailers
The same logic applies here as with our water and diesel bowsers: unbraked trailers rely on the tow vehicle alone to stop, and are only suited to lighter loaded weights. Once you’re running a 1,500L-2,500L trailer full of water plus the pump unit and chassis, you’re well into braked-trailer territory. Always confirm your tow vehicle’s rated towing limits and local regulations before ordering — see our braked vs unbraked guide for the detail.
Quick reference
| Format | Typical bar | Best for |
|---|---|---|
| Electric mobile (2.2kW) | ~100 bar | Fixed wash bays with grid power |
| Petrol trailer | 186-248 bar | Portable general industrial cleaning |
| Diesel trailer/jetting unit | 186-241 bar | Heavy-duty, continuous, off-grid sites |
| 210L trolley unit | 241 bar | Single-yard use, easy manoeuvring |
