Kärcher T 350 Wide Area Surface Cleaner

Had second thought about purchasing this following some of the bad reviews. However I'm glad I did as it works really well.The instructions are somewhat brief and to the point, but my main concern, having bought some Karcher "Stone Plug and Clean" was no reference to using detergents with this device whatsoever. The answer is you can't!! The pressure in use is too high, so won't "mix" detergent with the water. Probably obvious to a regular pressure washer user, but I think there should have been a line about this in the instructions. So the procedure we used was:-Brush the Patio Area well to remove surface mess - leaves, dust, grit, and the like.Hose the area down with the Vario Power Lance and detergent set to "MIX". This is the standard lance provided with all Karcher power washers (I think...ours is a K4). It'll foam up a bit and it's quick and easy to cover the whole area, without much splashing.Leave this for a few minutes to soak inThen go over the whole area with the T-350...as per the instructions. Best to do this twice, brushing the surface down between each 'blast' of the T-350...this'll clear the very dirty water left after the initial application...of course depends on how dirty your patio is.. ours was filthy.Had one very minor problem half way through the cleaning process...I noticed it stopped cleaning as evenly, and left spray marks. On lifting the T-350 off the patio, I could see the "rotor" wasn't turning. On investigation a tiny bit of grit had jammed the rotor against the housing...took a second to remove, and no more problems...We were very pleased with the finished result. However I should point out that the "dirt grinder" lance - as supplied with the K4 does as good a job as the T-350 and is better at clearing grass and weeds from block paving BUT.....and this is the best feature of the T-350...the dirt grinder covers everything within range with muddy water and rubbish - you can't help but splash the muck everywhere...the T-350 however, is brilliant at containing this and gets just as good results over 95% of the area covered.Hope this report addresses some of the negative comments....but each to their own!

I was kind of doubtful about how effective this would be, but thought I'd give it a try as I'm sick of getting covered in dirt when I clean the patio.The good news is, it works better than I expected, with no noticeable difference in cleaning power over the standard high pressure lance. The huge improvement is in the fact that water isn't spraying everywhere and it also seems to be quicker. I'd say it easily halved the time I normally took.I used it with a new style K4 FC, and had to change the nozzles due to it having lower pressure than the higher rated ones, but the other nozzles were included and easy to change.In use, I decided to just use the lance for quickly cleaning around up the edges of the patio, then I used this cleaner. You need to go backwards and forwards over the same bit to fully clean it, but that's no big deal, as it's still quicker than the lance.I also used the lance to wash away any pooled water after the patio cleaner had done its stuff, but that was quick and easy, not needing the usual slow close up high pressure effort.Equally, you can't use this on the vertical or horizontal surfaces of steps, as it doesn't have enough surface area to make it worthwhile or effective, but that's no big deal either.But when it comes to patios, this is an absolute godsend. What's even better, is that we'll now use it twice a year to keep the patio cleaner, as it's so easy and quick to use.This really is a great product, being such an effective time saver.

I ordered this to do a lot of brick paving/patio work. Initially after setting it up i tested it against the standard (min-max) lance and also the oscillating patio cleaning head. I have to say, massively impressed with this!!! It does slightly depend on your patio style and what you are trying to lift off it, but cannot fault this! Its 10x quicker than using the pressure washer lance and a good 5-10x quicker than the oscillating head. Don't bend and scrub like i initally tried, just set the desired pressure from the top, and then run the head back and forth a few times, you're done! It really is that easy!!!PROS:Quick, Simple and Easy on the Body, no heavy scrubbing needed.Great Brush to help with the cleaning process.Keeps the water contained so you don't end up firing dirty water all over your walls and windows!CONS:A lot of water contained in a small area, because you're not using the lance you don't end up blowing the water away as you would with the 2 lance mentioned above.Not that easy to clean the brush out but not really the end of the world!!A great product, i got it with a discount on the price from Amazon in the Spring offer, but all in all superb! Exactly what i wanted, if you want to clean your patio easily, then I don't think you'll regret it!!
