Zoom on the Kärcher K2 Compact

The Kärcher K2 Compact, a light duty pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • cleaning of painted or delicate surfaces
  • application of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Kärcher K2 Compact in use

The Kärcher K2 Compact

Its axial pump, which utilizes a 13 amp universal motor, may deliver a pressure of up to 1600 PSI (almost 27 times more than a standard garden hose) and a flow of up to 1.25 GPM. These values correspond to a cleaning power of 2000 Cleaning Units.

Since it is an electric pressure washer, the motor of the K2 Compact is started simply by an ON/OFF switch. The unit is ready-to-use with peace of mind, thanks to the included 35 ft GFCI cord.

Design & Handling

With its portable design and approximate dimensions of D7.7 x W11 x H19.6 in, the Kärcher K2 Compact makes mobility one of its core strengths. The handle adds to the K2 Compact convenience of transport.

Since the unit weighs only 14.5 lbs, it is very easily carried around. Among other factors, the plastic frame plays a role in this light weight. Even though the K2 Compact doesn’t have any wheels, their absence is fully compensated by this light weight.

Main Features

Along with the Kärcher K2 Compact itself, the package also includes a spray gun, a wand, a pressure hose and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The Kärcher K2 Compact is not equipped with a soap dilution mechanism, and thus, it is up to the user to ensure the detergent’s correct dilution ratio when using it. Detergent is automatically dispensed when the VPS wand is in low pressure mode.
  • Pressure hose: The unit comes with an easy-to-connect 20 ft high-pressure hose. However, it doesn't feature any proper storage solution for it (no reel, strap or hook).
  • Spray gun and wand: The included classic ergonomic spray gun and its VPS wand can be easily stored in a set of notches. The Vario Power Spray (VPS) wand allows you to conveniently switch from low to high pressure, and everything between, while you clean. Simply twist the end for infinitely variable pressure adjustment.

The Kärcher K2 Compact's performance versus other pressure washers

The following charts are provided to give you an idea of how the key specs of the Kärcher K2 Compact compare to similarly priced pressure washers.

  • The Karcher K2 Compact, a device which can produce up to 1600 PSI, is on the lower end of the pressure spectrum, among the electric pressure washers in the $70-100 price range. If you're going after the highest possible power of the water stream, one of the best in this price range is the WEN PW19 that can reach up to 2000 PSI.
  • When compared to devices in the above-mentioned price range, this washer and its 1.25 GPM (gallons per minute), is on the lower end of the achievable water flow. If you’re after the highest rinsing efficiency, one of the units with the highest water flow in the current price range is the Realm BY01-VBS-WT, that can deliver up to 1.65 GPM.
  • The K2 Compact has 2000 Cleaning Units (PSI x GPM), which can be considered low in comparison to other electric devices of this price. When it comes to the highest overall cleaning power in the current price range, one of the products at the very top currently is the WEN PW19 and its 3200 Cleaning Units.
