Kärcher K1800 Cube Pressure Washer — 1800 PSI, 1.2 GPM, CETA Certified, 3 Nozzles, Detergent Tank | Compact & Portable

The Kärcher K1800 Cube is a compact electric pressure washer designed for everyday cleaning around the home. With an 1800 PSI TruPressure output and a steady 1.2 GPM flow, it tackles dirt on cars, driveways, siding, and patios without taking up a lot of space. Independently tested and CETA certified, this unit offers reliable performance for routine chores that homeowners frequently face.

Three spray options unlock versatile cleaning capabilities. The 15° nozzle provides precise cleaning, the turbo nozzle powers through tougher grime, and the 65° soap nozzle applies detergents for a refreshed finish. All three nozzles connect quickly via a universal fitting, so you can switch tasks in moments. An integrated detergent tank sits on top for convenient detergent application, and it is removable for easy filling and cleaning when needed.

Practical design details enhance everyday use. The compact cube shape keeps the unit light (about 16.3 lbs) and easy to carry, while a dedicated back storage area stows the gun, hose, and wand when not in use. No tools are required to assemble the K1800 Cube, so you can start cleaning right away. The on/off foot switch allows for simple power control, and water flow is managed at the trigger gun for precise operation.

In real-world scenarios, you might refresh a vehicle’s exterior, lift algae from siding, revive a weathered deck, or rinse a driveway before sealing. The K1800 Cube is designed for garages, sheds, and tight storage spaces, and the included hose, adapters, and nozzle options make it compatible with standard garden setups for quick connections.
