With a 13-amp induction motor powering it, the axial cam pump of this unit is capable of achieving a pressure of 2100 PSI (approximately 35 times greater than that of a standard garden hose) and a flow rate of up to 1.2 GPM (CETA-certified values). Corresponding to these values is a cleaning power of 2520 Cleaning Units.
Kärcher ensures easy motor startup for this electric pressure washer, thanks to the K2100PS'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 K2100PS's commitment to mobility is evident through its portable design and approximate dimensions of D18.9 x W18.5 x H35.4 in. Built with an aluminum frame, this pressure washer prioritizes mobility and longevity, offering corrosion resistance and lightweight design for ease of use and durability. The folding handle enhances its mobility, while allowing for a convenient storage.
With a weight of 39.7 lbs, the unit is comfortably maneuverable for most users, allowing for efficient handling during cleaning tasks. While its motor adds considerable weight, Kärcher's decision to employ an aluminum frame helps keep the unit's overall weight in check. Still, the K2100PS's two 10" never-flat wheels ensure easy handling and maneuverability.
