- intense cleaning of hard surfaces
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
Powered by a 13 amp universal motor, its axial pump can deliver a pressure of 1800 PSI (around 30 times more than a standard garden hose) and a flow of up to 1.2 GPM (CETA-certified values). Combined, these values mean that the Kärcher K1800PS has a cleaning power of 2160 Cleaning Units.
Kärcher allows you to easily start this electric pressure washer, utilizing the K1800PS's 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 offers superb mobility, with a 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.
Standing at only 20.7 lbs, this model can be carried around very easily. Among other factors, the plastic frame plays a role in this light weight. A set of two 8" never-flat wheels also improves the ease of transport of the device.
Main Features
The Kärcher K1800PS comes with a spray gun, a wand, a pressure hose, 3 nozzles and a detergent injection feature, which are detailed below.
