Rated 5 out of 5 by from Great pressure Got this one to replace my old garage sale bought Karcher that finally pooped out. If it lasts nearly as long as my old unit, I will be very satisfied

Rated 2 out of 5 by from Did not last long Bought this unit a little over a year ago, will not build pressure now. Use maybe once a month to spray off vehicles.cycles on and off nonstop without trigger depressed. Stored inside always, in heated basement in cold weather. I guess i will find out if warranty is any good.

Rated 5 out of 5 by from Best value at this pricepoint Since reviews for all brands, makes, and models varied so much, I decided to buy the Karcher K1800 based on mostly good reviews, and price. Assembly was easy except I had a little trouble putting the handle on...had to get the angle just right. I encountered a user error, in that I was attempting to attach the water inlet valve backwards but after consulting a Karcher service rep the issue was resolved in very short order. Thanks again, Gabe! I purchased the K1800 to clean the vinyl siding on my house and intend to use it to wash my car and anything else that may crop up. The performance can only be described as excellent, the siding on my house looks new! I also used it to clean a toy bin that's been sitting outside for 4 years, and that looks great, too. The only caveat I have is longevity/durability...I won't know how reliable this unit will be until I use it repeatedly over the coming years but that's a gamble with any product.

Rated 1 out of 5 by from Keeps shutting off! Ive tried to use this twice but the machine keeps shutting off after only 30 min of use. Is this simply user error or ??

Rated 1 out of 5 by from Worked Once Purchased in May and used in September once and it worked fine. We used again after 2wks and the spray wand connection leaks when attaching both nozzles and surface cleaner. Time wasted trying to figure out why it leaked and the connector loosely fits with the nozzles and attachment. Returning and not happy it wasted our time.

Rated 1 out of 5 by from Not Happy I purchased this power washer to replace my older Karcher. I like the size and the mobility of the product. However none of my attachments fit this machine. I have an extension wand which doesn’t fit this washer! And yet it says it has universal fittings. Very disappointing! I will be returning this machine! Buyer beware!

Rated 4 out of 5 by from Great for smaller household jobs We've used this on our driveway, patio, brick around the house...it does a great job of removing stains/dirt/algae and making everything look fresh and clean. I've been pleasantly surprised by the performance. It's not heavy, so it's easy to move around without a huge hassle.
