KÄRCHER Pressure Washer K1800PS Cube — 1800 PSI TruPressure, 1.2 GPM, CETA Certified

The Kärcher K1800PS Cube is a compact electric pressure washer delivering 1800 PSI TruPressure and 1.2 GPM for everyday home cleaning tasks.

The K1800 Cube pairs a small footprint and lightweight design with CETA™-certified performance so you can wash cars, patios, siding, and decks without tugging around a heavy machine. It ships with three quick-connect nozzles (15° for general cleaning, turbo for stubborn grime, and 65° for soap application), an integrated removable detergent tank, a 20 ft M22 hose, and easy on-board storage for the wand and gun. No tools are required to assemble the unit and an on/off foot switch makes powering the washer simple while your hands remain free to control the spray.

What cleaning power and flow does this unit actually provide?

The K1800 Cube produces a rated 1800 PSI TruPressure output and moves water at up to 1.2 gallons per minute. That balance of pressure and flow is tuned for routine residential use rather than commercial heavy-duty stripping.

• CETA™ certified TruPressure testing for verified output
• 1800 PSI suitable for pavement, vehicles, and siding
• 1.2 GPM to conserve water while delivering effective cleaning

How do the included nozzles change cleaning results?

The three quick-connect nozzles let you match spray angle and force to the task. Use the 15° nozzle for concentrated cleaning, the turbo nozzle to tackle stuck-on dirt, and the 65° soap nozzle to apply detergent gently across larger areas.

• 15° nozzle: targeted, controlled spray for grime and wheel wells
• Turbo nozzle: rotating high-impact spray for heavy deposits
• 65° soap nozzle: wide, low-pressure coverage for detergent application

How easy is it to store, transport, and use around the home?

The Cube’s small dimensions (approx. 15.1 x 12.6 x 11.8 in.) and ~16.3 lb weight make it simple to lift, carry, and tuck onto a shelf. Integrated storage on the unit secures the trigger gun, hose, and wand, while the detergent tank stores or detaches for filling and cleaning.

• Compact cube shape fits tight storage spaces and small garages
• On-board storage keeps accessories organized and accessible
• Removable 0.3 gal detergent tank for easy filling and rinsing

What controls and setup features help me get started fast?

Assembly requires no tools and the system includes a garden-hose adapter for quick hookup. Power is controlled with an on/off foot switch so you can start or stop the washer without bending, while water flow is regulated at the trigger gun during use.

• Tool-free assembly for immediate operation out of the box
• 3/4" garden-hose adapter included for standard connections
• Foot switch for power control; trigger gun for flow control

Who is this for: The Kärcher K1800 Cube is designed for homeowners, car enthusiasts, and renters who need a portable, easy-to-store pressure washer for routine exterior cleaning. It’s ideal if you want verified, CETA-certified residential power without the size, weight, or complexity of a professional-grade machine.
