Karcher T250 Hard Surface Cleaner for Electric Pressure Washers (Deck, Driveway, Patio, Tool Accessory)

Received it yesterday and tried it out today to see how well it worked. I used it straight out of the box and it worked just ok. I only did a small section of my driveway and stopped. I went inside and was going to throw the box away when I noticed a piece of cardboard with 2 small nozzles attached (somehow I missed this when unpacking). I looked thru the user manual again to see if it mentioned what these were. Bingo...it said to use these nozzles for pressure washers under 1700psi instead of the ones that come attached. The next day I figured I would try again with the different nozzles since my pressure washer is only rated at 1300psi and WOW!! Almost finished the driveway in a fraction of time it normally takes and it looks beautiful. Seriously I wish I had taken a picture because my driveway went from a blackish color to a nice beige/white color, with none of those steaks from using the wand. I'm impressed because my karcher pressure washer is 15yrs old and is only rated at 1300psi and my driveway looks awesome after using this attachment. Highly recommend.Instead of just browsing quickly thru the user guide, I should have spent the extra 5 minutes reading it completely because it clearly states which nozzles to use per psi rating.

I used the T250 a couple of times with 5,540 k model and the feeling that I have is that it is a useful product, but it does not work exactly as advertised.Perhaps because the two nozzles on the inside of the brush out of the water allow a much lower pressure than the normal nozzle using direct and washer, so that the pressure is substantially reduced and therefore the power to starting the dirt .The great advantage of this product is the ability to concentrate all water under a small bowl and spread without wasting so much water.I think if it is worth and be more effective in wooden suprficies concrete.Hope this is helpful.-----------------------------------Util pero no perfecto.He utilizado el T250 un par de veces con el modelo k 5.540 y la sensación que tengo es que es un producto útil, pero que no funciona exactamente como se anuncia.Quizá sea porque las dos boquillas en la parte interior del cepillo permiten una salida del agua con una presión mucho menor que utilizando la boquilla normal y directa de la hidrolavadora, por lo que la presión se reduce sustancialmente y por ende el poder de arrancar la suciedad.La gran ventaja de este producto es la posibilidad de concentrar todo el agua bajo un recipiente pequeño sin desperdiciar y esparcir tanto agua.Creo que si vale la pena y que sea más efectivo en suprficies de madera que de concreto.Espero que esto le sea de utilidad.

Package arrived quickly and parcel was undamaged, but on first use it was evident that one of the extension sections had a big crack in it, which made that part of the tool unusable. Fortunately the tool could be used with just one of the extension sections attached. Since it had been shipped overseas I couldn't return it cost effectively, but Amazon customer service provided a partial refund which was a satisfactory outcome. (Although I'd rather have the full extension of the device to avoid backache!)In my opinion device doesn't make the task of cleaning the pathway significantly quicker, but it certainly does make a lot less mess (no wall splatter to clean off). The reason I haven't given it a higher rating is that water has a tendency to pool underneath the rotary during use, which makes it more difficult to see what you're trying to clean. With the standard sprayer head attached it blows the water away as you clean, so you can clearly see how well the area has cleaned before moving on. I found that with the rotary attachment I had to keep going back over areas that I had already covered. If you haven't got a particularly large area to clean, it's probably not worth the investment, but if the area you have to clean is near windows or painted surfaces that you don't want to have to spray down with a pressure washer, then well worth grabbing it. It is particularly effective on very flat paved areas, e.g. around the pool, but obviously less useful on uneven crazy-paving.

I have never used a pressure watcher in my life. After watching Youtube videos on the Karcher 2.300 1600 psi & this attachment i bought both. I swear i cleaned my walkway and steps in 30 minutes! The area this attachment cleared was incredible. You just keep it flat, and pull. It hovers in the water and glides. It makes the job about 5 times faster!I used it on steps from the slab going right to left. Then the top landing. All i had to do to finish job was use the dirt blaster attachment from the pressure washer and clean up the edges and corner on steps.About a month prior, i hand scrubbed dirt and moss off the walkway and steps using oxyclean - everything looked pretty good but it was back breaking work. Upon closer inspection i could still see moss.After using this, it was like night and day, it was cleaning off so much grime-everything looked spanking brand new! I had such a blast, i almost volunteered to do my neighbors walkway too! Maybe next time.Note: You must use on flat surface, clear of rocks and debris.

I bought this to use with a Karcher K5.540 to clean my concrete driveway because my son borrowed my gas pressure washer and he does not live nearby. It doesn't clean squat. One problem is that the Karcher K5.540 has less pressure than my Dobie, Max. I would like to try it with my gas pressure washer when I get it back but I doubt that the fittings will match. I guess Karcher does not want anyone to hook up their attachments to a gas pressure washer because then you would know just how useless is the Karcher pressure-less washer. I will try to find some fitting at Lowes and Home Depot and if that fails then into the recycle bin goes this alleged driveway cleaner. I don't have any wood decks or other surfaces of wood so that makes this useless if it can't hook up to a gas pressure washer. No more Karcher anything for me.
