DERA DK-K6 High Pressure Washer
powerful Cleaning. Effortless Results.
1900W Motor | 20–160 Bar Adjustable Pressure | 480 L/H Flow Rate | Self-Priming & Direct-Connect | Overheat + Leakage Protection
The DK-K6 High Pressure Washer from DERA is built for one purpose: to make every cleaning job faster, safer, and more controllable. Whether you‘re rinsing the family car, blasting moss off a patio, or stripping years of grime from a workshop floor, the DK-K6 High Pressure Washer adapts to the task without compromise.
It pairs a 1900W pure-copper motor with a 20–160 Bar adjustable pressure system and a high 480 L/H flow rate, then wraps it all in a compact, portable housing with built-in safety protection. Hook it up to a tap, dip its inlet hose into a bucket, or pull water straight from a tank — and get to work.
1. DK-K6 Adjustable Pressure 20–160 Bar — One Machine, Every Task
Fixed-pressure washers force a compromise: too harsh and you risk damaging paint or wood, too gentle and stubborn grime stays put. The DK-K6 High Pressure Washer ends that trade-off. A simple twist of the on-board pressure dial sets the output anywhere from a soft 20 Bar mist to a 160 Bar high-pressure jet — and you can adjust on the fly while the machine is running.
Pair with the adjustable nozzle — twist between a 0° concentrated jet for cutting power and a 40° fan for wide coverage. Pressure plus spray angle gives you complete control over how aggressively you clean.
2. DK-K6 1900W Pure Copper Motor — Steady Power Under Load
Headline wattage is meaningless if power drops the moment you pull the trigger. The DK-K6’s 1900W pure copper motor is built for sustained output — it holds 160 Bar without sagging, even on long cleaning sessions. Copper windings deliver better thermal conductivity and longer service life than aluminum equivalents, so the motor stays cooler, runs quieter, and lasts longer.
In practical terms: when you switch from low pressure to high mid-job, the motor responds instantly. There’s no lag, no power dip, and no need to wait between passes.
3. 480 L/H Flow Rate — Pressure Without Sacrificing Volume
Pressure cuts grime; flow rate carries it away. Many cheaper washers boost their pressure rating by starving the flow, which leaves dirty water sitting on the surface you just cleaned. The DK-K6’s 480 L/H flow keeps the rinse moving — soap, mud, and debris get flushed off the panel instead of streaking across it.
High flow also means low-pressure mode is gentle but never weak. A soft 30 Bar rinse with 480 L/H still moves real water, so you can foam down a car or water plants without it feeling like a trickle.
4. Self-Priming + Direct-Connect — Use It Anywhere
Most pressure washers are tied to a garden tap. The DK-K6 isn’t. Two water intake modes mean it works wherever you need it:
Self-priming mode — drop the inlet hose into a bucket, water tank, or rain barrel. Ideal for outdoor sites, balconies, car parks, or anywhere a tap isn’t within reach.
Direct-connect mode — thread the inlet onto a standard garden tap and start cleaning immediately. No priming, no fuss.
Why this matters: for car detailers, mobile cleaners, and anyone working away from plumbing, self-priming turns a 20-litre bucket into a complete water source. For homeowners with a tap nearby, direct-connect is plug-and-play.
5. Built-In Safety — Overheat + Leakage Protection
Water and electricity demand serious safety engineering. The DK-K6 ships with two layers of protection as standard, not as add-ons:
Overheat protection — if the motor temperature climbs past safe limits, the system cuts power automatically. Once cooled, it restarts ready for the next job. No burnt-out windings, no service calls.
Leakage protection (RCD) — the power cord includes a residual-current device that detects ground faults in milliseconds and disconnects power before current can reach you. Essential when you’re spraying water in a live electrical environment.
⚠ Always pull the trigger after switching off to release residual line pressure before disconnecting hoses. It’s safer for you and extends the life of every seal in the system.

Quick Start Guide
Assemble the unit. Connect the spray gun, high-pressure hose, and inlet hose.
Connect water. Either thread onto a tap (direct-connect) or drop the inlet hose into a bucket / tank (self-priming).
Plug in and switch on. Squeeze the trigger to bleed any air from the line.
Set the pressure. Rotate the dial — start low, then increase to the level the job needs.
Choose your spray angle. 0° jet for concentrated impact, 40° fan for wide coverage.
Clean. Keep at least 30 cm from delicate surfaces and work in steady passes.
Shut down safely. Switch off, then squeeze the trigger to release residual pressure before disconnecting hoses.
Frequently Asked Questions
Q: Do I need to switch off the machine to change the pressure?
A: No. The pressure dial works while the unit is running — turn it during use and the output adjusts immediately.
Q: Is low-pressure mode really safe for car paint?
A: Yes. The 20–60 Bar low range is below the output of most professional drive-through car wash machines. Combined with the 40° fan nozzle, it safely lifts dust, salt, and foam without risk to clear coats.
Q: Can the DK-K6 draw water from a bucket?
A: Yes. Self-priming is a built-in feature. Just drop the inlet hose (with the supplied filter) into a clean water source, and the motor will pull the water up.
Q: What surfaces should I be careful with at high pressure?
A: Soft wood, old paint, loose render, and unsealed grout can be damaged at 160 Bar up close. Stay at least 30 cm away, use the fan spray, or drop to medium pressure on these surfaces.
Q: Will the overheat cut-off damage the motor?
A: No — it’s the opposite. The cut-off protects the motor by stopping it before it can be harmed. Once the motor cools (usually 5–10 minutes), simply restart and continue.
Q: What voltage does it run on?
A: 220–240V at 50/60Hz, suitable for standard domestic and commercial outlets across Europe, the Middle East, Africa, Australia, and most of Asia.
