    the karcher to the test

    It has true psi power. the connections are easy to get to and its compact design make it very easy to start or stop use in an instance. Ive had the campbell hausfeld and I'll give it a 3 at best. The campbell's psi is much lower output even with the power tip on that is suppost to increase its psi.Plus u save money over the campbell. I use my karcher for drive-thru and inside restaurant cleaning as well. The only con to the electric is a short hose. Upgrade to a higher psi hose with longer length to get around easier and reach more areas. Also, you don't have to worry about someone running over the hose with a car. This washer saves me hundreds every month that I use it. I have a 3100psi gas pressure washer and its such a high cost and bother to lug around. If it does the job for a business it will do it for your home. Hope this review was helpful and don't forget to upgrade your hose.

    This is a good power washer at 1800PSI, and all the parts and pieces work as advertised. The only complaint is the on/off switch that gets stuck and must be pulled out to make it actually turn off the motor. I don;t know whether this is a design flaw or a manufacturing flaw, but the switch needs some work The work-around is to push the "reset" button on the built in GFI on the power cord.

    First, my quals: I'm a retired Marine after 32 years. I'm an auto mechanic, aircraft mechanic meaning I have at least average mech ability. I owned the smallest Karcher (little yellow pig) for years and loved it! I wanted to get more power and convenience and I upgraded (I thought) to this Karcher. I owned this model for a few months, used it 5-6 times for siding, driveway, car wash. You do not get enough increase in power to justify the price increase. The hose reel is a joke, it's a work out to use and winds the hose too small so of course it kinks when un-rolled. Unwinding the hose isn't fun either as with it being on top, it's top heavy and will tip if you try to pull the hose out. Top heavy is a problem while you're using this machine. The hose connection is "inside" the reel so it pulls over easily which of course leads to the breaking of the cheap plastic parts. The water inlet is in the bottom front which causes the hose to pull the pump housing to and fro as the port isn't supported. The high pressure wand is unreliable with the tip having two plastic pieces mated together and only one rubber o ring. The inner piece cracks and then you just have a fancy hose. Overall, if you need PSI you'll save money in the long run to just get a gas operated unit.
