Description
Zoom on the Kärcher K1800PS
The Kärcher K1800PS is a light duty pressure washer, and enables:
- complete cleaning of hard surfaces, vehicle washing, and surface prep for painting
- applying detergent and cleaning solutions, and rinsing surfaces
- spot cleaning of hard, unpainted surfaces, and removing stubborn stains
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
With a 13-amp universal motor, its axial pump delivers a pressure of 1800 PSI (roughly 30 times more than a standard garden hose) and a flow of up to 1.2 GPM (CETA-certified values), resulting in the Kärcher K1800PS's cleaning power of 2160 Cleaning Units.
Kärcher ensures easy motor startup for this electric pressure washer, thanks to the K1800PS's convenient ON/OFF pedal. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.
Design & Handling
The Kärcher K1800PS is very mobile, due to its hand truck design and approximate dimensions of D17.5 x W16.5 x H33.1 in. The folding handle enhances its mobility, while allowing for a convenient storage.
This unit's low weight of 20.7 lbs ensures easy maneuverability, allowing you to tackle cleaning projects with minimal effort. Its plastic frame plays a role in ensuring its lightweight profile. Further enhancing its lightweight design, the unit features two 8" never-flat wheels, streamlining transportation and maneuverability.
Main Features
The Kärcher K1800PS's package includes a spray gun, a wand, a pressure hose, 3 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: A removable 0.3 gal tank ensures storage for detergent within the pressure washer. As the Kärcher K1800PS does not include a soap dilution mechanism, it's essential to ensure proper detergent dilution before operating the pressure washer. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
- Pressure hose: The unit comes equipped with an included 20 ft high-pressure hose, which can be neatly stored on the unit when idle, thanks to a dedicated slot, ensuring easy access and organization.
- Spray gun and wand: A front sheath enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: The table below shows you the 3 included nozzles and the surfaces they're the most appropriate for.
15° | Soap | Turbo | |
|---|---|---|---|
| Concrete, brick, masonry | Suitable | Suitable | Use with caution |
| Siding, gutters, house | Use with caution | Suitable | Not recommended |
| Fencing, deck, patio | Use with caution | Suitable | Not recommended |
