What are (hot water) pressure washers?
pressure washer These are among the most important tools in professional cleaning. Using water applied to the surface under high pressure, they can be used to remove dirt and grime. Dirt, dust, moss and loose debris remove effectively.
Hot water pressure washer go a step further: Through the interplay of high pressure and high water temperature solve it yourself Fats, oils and stubborn dirt Significantly faster and more thorough than cold water-only devices. This makes them ideal for Industry, trade, agriculture, vehicle fleets, construction and demanding private applications.
In this category you will find at GRAEFER MASCHINEN both a powerful hot water pressure washer from Daewoo and a robust cold water unit – both consistently designed for professional use designed.
Who are these pressure washers suitable for?
The devices offered here are particularly aimed at:
Building cleaners && Service Providers – Facades, terraces, parking areas, outdoor facilities
Demanding private users – if the yard, house and vehicle fleet are regularly and thoroughly cleaned
Whether Hot water or cold water Whether or not to use a hot water cleaner depends on the type of soiling: where oil, grease, protein or stubborn deposits are involved, hot water is the best option – for normal soiling, a cold water cleaner is often sufficient.
Hot water vs. cold water – when to use which system?
Hot water high-pressure cleaners are the "Workhorses" for stubborn dirt, while cold water appliances are more than sufficient for many everyday applications.The most important differences:
Hot water high-pressure cleaner
Very effective on grease, oil and encrusted deposits
Reduces cleaning agent requirements and working time
Ideal for Vehicles, machines, engines, workshops, agriculture and industry
Cold water high-pressure cleaner
Ideal for general cleaning tasks such as terraces, driveways, garden equipment, vehicles
Less complex in design and handling
Often more compact and lighter, ideal for mobile use around the home and business
This category covers the Daewoo DHPW 7300 (Hot water, diesel) and the Daewoo DAW400E-3 (Cold water, electricity) cover precisely these two application areas.

Selection criteria && Interpretation
When choosing the right pressure washer, you should consider not only your budget but also the... Work tasks and the degree of pollution Keep an eye on it.
Type of pollutionOil, grease and stubborn deposits → hot water (DHPW 7300); general dirt → often cold water (DAW400E-3) is sufficient.
Location: Fixed location with electricity → electric appliance makes sense; yard, stable, construction site with variable positions → diesel hot water appliance is advantageous.
Frequency of useDaily, heavy-duty professional use → robust hot water system; occasional/changing locations → mobile cold water unit may suffice.
Surfaces &materials: sensitive surfaces (e.g. Materials such as old plaster and softwood require adjusted pressure and nozzle selection, regardless of the device type.
Use of cleaning agentsHot water often reduces the need for chemicals – important for environmental regulations and operating costs.
A sensible combination could be: Daewoo DAW400E-3 as an "everyday device" plus Daewoo DHPW 7300 for heavily soiled machines and special tasks.
Safety, operation && Maintenance
High-pressure cleaners – especially hot water units – are developing high forces and temperaturesSafe operation and regular maintenance are therefore essential.
GRAEFER MASCHINEN will help you clarify the following points:
What types of surfaces and soiling occur regularly?
How frequently and for how long should the devices be used each day?
Are electrical connections available, or only mobile fuel supply?
Are there any special requirements for Environment, emissions or use of chemicals?
