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.

The Kärcher K1800PS's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher K1800PS compare to similarly priced pressure washers.

  • With a maximum pressure of 1800 PSI, the Kärcher K1800PS finds itself within the anticipated pressure band among electric models priced between $100 and $120. For those prioritizing maximum water stream power, consider the Simpson CM60976, boasting 2300 PSI, as a standout performer in this price range.
  • In the aforementioned price range, this washer, with 1.2 GPM (gallons per minute), is placed on the lower end of the GPM scale. If rinsing away debris most efficiently is your priority, one of the devices with the highest GPM in this price range is the Sun Joe SPX2688-MAX, which can reach up to 1.8 GPM.
  • Featuring 2160 Cleaning Units (PSI X GPM) in total, the K1800PS lands within the average cleaning efficiency range for similarly priced electric units. If you are after the highest overall cleaning power, the WEN PW1900 with its 3200 Cleaning Units is one of the products that can achieve the highest cleaning efficiency in this price range.
