Freeze Caution
Own a slightly older model than this one but it has the same Trigger gun as this model. Unit works well and have had no problems with it. Takes a little while to set up with all the hoses, electrical and loading of detergent but once operating it does the job. I live in climate where it gets below freezing and thought I drained the unit prior to winter so left it in my garage. Big mistake. The trigger gun has a chamber in it that doesn't drain so the water froze and cracked the plastic. Leaked so had to replace it ($40). If you live where it gets below freezing I strongly suggest you bring entire unit inside for winter or at least remove the trigger gun and store that inside.

Robustness
I've had a consumer grade Karcher electric pressure washer for a number of years that I purchased from Costco, and the one listed here is no different. It has served me faithfully for many years until yesterday, when I stepped on the input garden hose just in front of its input hose bib - crack!! (*&#$*&(*&#$

Its input hose bib was plastic (polycarbonate?) and not strain relieved!!!

I dissasseble the plastic case (deeply recessed torx screws!! - no problem) and discovered that the plastic hose bib is integrated into the cylinder head and was non-replaceable.

Karcher's web site has no useful consumer information re: non-waranty repairs or parts. Only non waranty repairs are for pro-grade gas washers (which have nice brass hose bibs by the way). No parts list available for my model and discontinued.

I ended up encasing the cracked hose bib with epoxy putty. Sealing the margins with RTV silicone, then conpressing the RTV with adhesive conpression tape, so maybe I can finish my deck project before having to buy a new washer.

What I find disheartening is here you have a moderately expensive piece of equipment, ~$200, with moderately expensive components (electric motor, precision machined pistons, check valves, GFI switch, etc.) and it's completely destroyable by a non-replaceable, non-strain relieved, externally exposed, cheap plastic hose bib! They could have put in a brass one, or mechanically supported the plastic one, or even mechanically decoupled the whole thing by a short flexible section of hose!

great home pressure washer
This is my first pressure washer and I have been impressed with its performance. I have cleaned my pool decks and coping as well as my driveway. I thihnk it takes a longer than a gas powered model but it also does not damage the deck. I am pleased.

Karcher Power Washers A Waste of Money
I stupidly bought this product and it virtually never worked. They have designed this (and all of their other products) so badly that if you can actually get through a complete job, you deserve an award!! The reset switch goes off constantly and the "temperature sensitivity switch" gaurantees that unless you live the Antartic, it wil not work outside under any conditions. This Karcher product is a complete waste of money!!!! Save yoursdelf a lot of time and frustration and buy anything other than Karcher!!!

Don't Buy A Karcher
DO NOT BUY A KARCHER!!!!
I had an electric pressure washer model K3.86 that started pulsing and leaking after less than a dozen uses and approximately 16 months. I called the 800 number on the unit and was transferred to tech support. They told me it sounded like broken seal or something and asked for my zip code to find the nearest service center. I took it in to their recommended service center and agreed to a $40.00 bench charge to diagnose it, only to find out it had a cracked manifold and wasn't worth the price (over $100.00) to fix it. I then called Karcher just to complain about the quality of their product and was told that I should not have taken it locally because all electric units need to go to Illinois for repair. So not only am I throwing out a $160.00 pressure washer, but I am out $40.00 because Karcher admitted to incorrectly telling me to take it to a local center. And they will not even reimburse me the $40.00. Another local center said that these units are throw-aways made of cheap plastic parts and that you should buy a different brand (such as a Husky). Do yourself a favor and do NOT buy a Karcher. They truly are junk.
