: Kärcher 300 T-Racer Patio Cleaning Pressure Washer Accessory

Rating: - Marvelous
If you prefer cleaning the patio one inch at a time and getting drenched in the process this is not for you. The design and functionality of this gadget is superb. I cleaned the patio and 100 feet of pathways in 2 hours - It used to take a full day. It's as easy to use as a hover mower.

I was almost put off purchasing this item by one previous very poor review,but after using the cleaner a couple of day,s ago I can only assume that the cleaner tried by that reviewer was faulty.
Having spent a lifietime in engineering I am familiar with all kinds of commercial equipment so I can write on this with some authority.
1)Easy to assemble.
2)My drive (blocks) had not been cleaned since laying 12 years ago and was black.
3)Switched my K4 pressure washer ans the the result was startling,immediately revealed was the original shades of red block paving,one slow pass was all that was needed,my drive has a gentle slope to a slot drain so little residue was left behind,i cannot fault ths cleaner.
I lent it to a friend who cleaned a block diveway twice the size of mine,block paths and a rear slab patio with same excellent result.
Worth every penny,i would assume it would work as well on decking and walls.

I bought this at the weekend, very sceptical having read the different reviews but I can honestly say its probably going to save me 4 times the mount of time it would have taken to clean my blocked drive with just the lance, where there is a lot of moss in between bricks you will have to go over a few times to get it up but its hardly hard work!

The best time saving device I have bought for a long time..

I was ready for the spring clean of my drive and front and rear patios. Picked up this gadget because it looked promising.

Out of the box the item looked sturdy and had the usual quality feel associated with Karcher. The cleaner is a large disc with a nylon brush which makes the contact with the floor. underneath there are 2 nozzles which spin on a propellor. There are 2 other nozzles which you have to change depending on your make (mine is a K3) this was a little fiddly, but not difficult. The lance extension is sturdy and there is a locking collar for additional support. On the body there is a dial to adjust pressure and a sliding mechanism to open and close a louvre which puts it into a hover mode.

I got everything up and ready and started off on a bare concrete driveway. I was immediately impressed with how little spray out there was, nice and clean. That is where I stopped being impressed.

The nozzle spray is very fine so there is only a pencil thin cleaning line. It isn't fast or powerful enough to move at any speed. So moving back and forth is done slowly and the clean isnt as deep as I wanted. I had it on full blast power and although it cleaned, it was nowhere near as fast or as clean as the cone shape lance I use. The "hover" slide switch made no difference whatsoever. The brush drags on the ground no matter what setting you have. This is difficult when working on a steep drive as mine is.

Moving onto a flat patio was a bit better for movement, but I was not happy with the result. When I encountered some moss in the joints of my patio, it took ages of back and forth slow moving to try to dislodge it. The only real benefit is that my windows and door didn't get covered in muck, but that is never a problem, I just give them a quick low pressure swill.

The other negative point is that as you are cleaning, the dirty water doesn't go anywhere other than usual run off. With a lance you can sweep the dirty water away. Lastly if you want a complete clean, you still have to attach a lance to get in the corners, edges and nooks and crannies.

When I went to my back patio I gave up and went back to the cone lance with extension piece to ease the lower back strain. It does the job in half the time, half the water and half the electric.

I guess that the patio cleaner would be good on decking as it is not so severe. Ideal if you have the time or are not particularly concerend about the end result and I would recommend it if you don't like getting dirty windows and wet feet and it is certainly a must for delicate stone work where erosion is a concern.

If you don't mind getting wet and having a face full of patio dirt, stick to a cone jet with extension lance. Much more fun.

Mine is being returned less that 6 hours after delivery

Rating: - Almost the perfect attachment.
First of all I bought this and amazon had it deliverd across the Irish sea in a few days so congrats to them. Excellent service as normal. The device itself has certainly made the job of cleaning the patio easier. It definitely reduces those awful splashes all over the walls and windows and therefore means that it is much quicker and tidier than the lance. If you are very fussy it could be said that it doesnt get the job done just as well as the lance. I "wrote" my childrens names onto part of the dirty patio and then went over it with the T300. You could still see the names after I had washed the area with the T300. Having said this however, I still think that it was a good buy as I am now more likely to clean the patio as the device is very user friendly.
