    Pros: Runs and runs and runs
    Cons: Loses Pressure when uploader sticks

    Summary: Like others, I like the Karcher 2400 except when it loses the high pressure state. I just fixed mine as someone suggested, by greasing the uploader. It's relatively easy and the pump is back to full operating state. Just follow these instructions: ... read more

    Pros: The HONDA motor works unbelievably great
    Cons: The pump leaves much to be desired

    Summary: The Karcher from Costco worked well for a while but developed the identical loss of power described in dozens of these reviews. The fix recommended at the very end works great -- I guess Karcher cannot put it in their maintainence manual for fear ... read more

    Pros: Respected name
    Cons: Lousy product

    Pros: Relatively cheap to buy
    Cons: Pump is junk. Customer service is non-existent at Karcher.

    Summary: I too had the pressure problem so many of you had...luckily I stumbled upon the link through this site that has literally a 5-10 minute fix to the problem. The only thing that I did different from the instructions was that I tied a rag over the hole (on ... read more

    Pros: - Great engine - Good price
    Cons: - Poor unloader valve, causing the unit to not work.

    Summary: WHEN it works, this power washer is great. The Honda engine starts every time, right off, but the pump is a problem. With only a few hours on it, the unloader valve started failing. From what I have read and heard, this is very common. They should ... read more

    Pros: Honda engine starts each time.
    Cons: Pump problems will render this unit useless.

    Summary: Unloader valve (pump)problem. Those that gave it 5 stars obviously must work for the company. Just read how they wrote the review. Does it sound like statements from the company? After calling several service centers listed on the Karchers web site. ... read more

    Cons: Not a good machine for people that don't like fixing things (will need fixing)
