5.0 out of 5 stars Excellent Results 24 Oct 2008
This is a fantastic piece of kit. Lockblock patio and PVC Gutters/ Soffits now sparkling. Dirtblaster does the business.
Only one problem, relating to the suction hose. The instructions (page 6)state "pull detergent suction hose as far as is required out of the housing". The hose is very short and too easily pulled off the connection. Now I have a suction hose which is detached from the machine !!
I suggest the following modifications 1) longer suction hose, 2) Fix the suction hose with a proper mechanical connection (it is presently a push fit which is useless), 3)colour code the hose to indicate when it has reached the end of it's travel.
Otherwise great result.

5.0 out of 5 stars A Real Blast! 26 Feb 2009
By Menders
Verified Purchase
I've owned this product for nearly a year now and have been very pleased with it.

Its main duties are cleaning the patio and driveway and for which it does a superb job. The variable power setting is very useful. The range of Karcher accessories means there is usually some attachment available to make a job that bit quicker and better.

I would agree with some of the other reviewers that the suction hose could be better designed but it's never presented me with a real problem, just something to be aware of rather than to be avoided.

An excellent product which I have never regretted buying.

5.0 out of 5 stars Compact, Powerful and Versatile 21 Oct 2008
Verified Purchase
I purchased this pressure washer to replace a well used but almost worn out twelve year old Karcher 411A that had given excellent service. This machine is quieter, probably more powerful than the 411A when it was new and with its variable output power, wheels and storage provision is more versatile. I was also pleased with the productive communications, fast delivery and attractive cost.

1.0 out of 5 stars Only lasted just over 2 years 11 April 2009
I have now had this pressure washer for just over 2 years which i bought here on amazon and it is now next to useless. It has only been used about once every 3-4 weeks in that time and now when it is switched on with the water supply connected it pulses on and off every second and the water pressure is way down. i have looked online and there are a lot of similar problems with all karcher washers and the general opinion is that the unit is broken and needs a new cylinder head. it seems 2 years is the time you get before they start going faulty so be aware of this if you decide to buy one.

5.0 out of 5 stars Karcher K3.9 4 Feb 2009
I have found this Karcher washer to be a superb purchase. It is easy to set up, easy to use and does an excellent cleaning job on the car. I only wish I had purchased one earlier. I can recommend this product to anyone.

4.0 out of 5 stars karcher k3.99mb pressure washer 21 Feb 2009
excellent product, especially with the dirtblaster lance included has great power. the only problem is the vario lance is not as powerful as expected and the suction hose takes time to work, even with these slight problems the machine is well worth the money

4.0 out of 5 stars Good piece of kit 19 Mar 2009
Easy to assemble - no problems with instructions. decent power in unit for cleanig my car and patio. Only a couple of niggles - power cord a little short this restricts the usage a little but an extension lead sorted that and the hose for the detergent is way too short. thanks to previous review I didn't rip it out of unit. Very pleased for price.

1.0 out of 5 stars had it two years and it leaks badly 20 Feb 2010
This is the first pressure washer I have owned and it performed very well for some time. I have had it for two years and during that time has had two episodes of leaking badly. Despite two repairs it keeps producing more leaks. It does not function at all now. Beware, as other reviews state the potential for leaks. I shall buy another brand next time.
