Karcher K5 740 pressure washer review
Electric pressure washers require less maintenance, but you shouldn’t pay the price of a gas model for an electric with a mixed bag of attributes. This Karcher pressure washer was effective at stain removal but not impressive at cleaning overall. It has two nozzles–one adjustable and one for soap. The hose reel is attached at one end, so you only unreel what you need and easily rewind it after. But there’s a quick connect only for the wand end of the hose. We liked the built-in soap tank and the flow control for the cleaning agent. The trigger lock, however, must be manually set. Generally, you could do better for the price.
Karcher K5 740 pressure washer Test Results
Easy to move and transport. Easy to operate — just plug it in — but may need an adapter for some outlets. Very convenient hose storage, built-in reel with only a wand connection. Cord is very easy to wrap and store. Wand very easy to remove and use. Very easy to use and read on-off switch.
The Karcher K5 740 is part of the Pressure washer test program. In our lab tests, Pressure washer models like the K5.740 are rated on multiple criteria, such as those listed below.
Cleaning: Versatility and efficiency in cleaning a range of surfaces. The better performers have multiple spray patterns that can cover various cleaning chores, from light, superficial cleaning to deep cleaning of concrete, decking, and other hard-to-clean surfaces.
Power: A combination of pressure, measured in pounds per square inch (psi), and flow, measured in gallons per minute (gpm). Higher pressure results in better cleaning of a given surface; coupled with a higher flow as well, you’ll get the job done the fastest.
Noise: A combination of measurements, based on dBA, reflecting the proximity of the operator to the pressure washer. While our Noise score averages measurements taken close by the machine and at the end of the hose’s typical reach, we strongly strongly recommend hearing protection for working close by a gas-powered model in particular.
