Decent unit if you have an electric power washer and want to clean up a patio or driveway. If doing a huge space I would opt for something larger that can handle more psi on a gas unit, otherwise this is worthy especially at this price. I just snagged the 1800 PSI Greenworks from Lowes for $59.99 I am going to pair with this.

Well, if it's underpowered it only means the power washer is but not the caster. I don't believe that has anything to do with it... Seems like it just spins. If your washer has sufficient power it should spin faster.

I think the logic here is that given the washer is already not very strong, paring with this attachment would further decrease the psi. If I'm not mistaken it has two water outlet and the spin motion itself certainly cost some power as well. In the other thread, people reported using the washer to clean the driveway/patio and had good results. It probably means that the power of the pressure is just borderline sufficient to do the job, but would become underpowered if puting this on.
Just pure speculation though. I too just bit the $59 deal, after seeing the positive reports on cleaning the patio. I'm now trying to gather more information and decide whether or not to get this.

Quote from ccbowers :
I bought the same Greenwworks deal and was wondering if these work well at that lower PSI and water volume. I have a more powerful gas pressure washer with surface cleaner that works well, but am unsure this will be useful. Maybe if I had a deck, but I have just concrete surfaces to use this.
I have a 3000psi gas pressure washer and i bought a similar surface cleaner to this by Karcher and even though it was only rated for 2300psi, I was blasting 3000 through it no problem and I've done the job at least 8 years in a row and its held up, but its certainly on its last leg. I figured I would give this one a try for $20. Not so sure the 1800 psi will be powerful enough, but in my case I see myself using it for touching up areas, or for quicker jobs when I don't want to break out the gas machine. Seems like reviews are decent, but not great, so time will tell.

They sell these really nice stainless steel ones that are 14"-16"+ for around $50-$60+ on Amazon, eventually I'll probably buy one of those for my gas machine to get the job done even quicker.

That makes sense if the pressure is split between two heads that rotate. FWIW, these were on clearance on SD through Lowes last year for $10. That's the lowest I've seen it.

With these sorts of things, you have to test it out first on the kids to make sure there's no risk to the cat.

Correct.
Can you expand one the machine you used? The psi etc? Would save a lot of people time and having to go through amazons return process.

I've used this with a Greenworks 1800 psi electric washer on 2 smallish patios fairly often for three seasons with no issues. Works as it should.

It's very underpowered, I'm returning mine as well.
Pressure is a function of the power washer you attach it to though. Can you explain how it could be "underpowered"?

I ordered this yesterday and just received my delivery from Amazon. The one that got delivered came with a foam cannon and a set of nozzle tips. That happen for anyone else?

Was supposed to receive mine yesterday but it was delayed for delivery today. That would be sweet if that was the case!

yes very odd, someone at amazon messed up?
The nozzle tips aren't worth much but the turbo nozzle and foam cannon are probably worth about $30 together.

this is a really slick deal if a lot of people got the whole kit......Wink
