I am looking at purchasing an electric pressure water blaster . I plan to use it for cleaning pavers and concrete around the house, blasting flaking paint off steel and 4WD cleaning. As we have acres of mouldy paving or so it seems, I thought a machine with around 2000 psi and with as much water flow rate as possible , as I have been told that the key to a good machine is the water flow rate. It would have to be 240 volts, 10 amps too.

As it will get a fair bit of use I need something pretty sturdy and reliable with good backup service etc.

I have been looking at machines such as karcher and Stihl etc. If anyone has any ideas, preferences or information on sortintg through the maze of such machines on the market, I would be grateful.

Gerni, don't waste your money on Karcher as they have some plastic components in the pump while Gerni are metal. Our Gerni Crown has lasted twice as long as the Karcher (which we fixed twice) which is now landfill.

They cost a bit more but last a hell of a lot longer.

Be careful with the water restrictions where you are. In SA it is naughty to use water to clean pavers.

Here in SE QLD it is also verboten...I bought a 120 litre plastic container and fitted a click on hose fitting to it. The Mrs fills it up with washing machine water and I use that to clean pavers and concrete via the Gerni.

The only proviso is that you must get all the air out of the hose (prime it) before firing up the Gerni.

Regards,

Greg

Good point Pajman

However I am in Darwin and it is the wet season. I do not like wasting water, but up here we are lucky to have more water than we need. Our rainfall is around 2.5 metres pa.and mould grows while you watch it.

Half your luck!

I spent 6 years up there and will be visiting (for work) again in December. Have the storms started yet? I was up there 3 times last wet and didn't even see rain.

Storms have not started yet Pete

This morning at 7 am it felt like a dry season morn. Come 9am however and she is pretty muggy.

This dry has been one of our best. I would expect them to start on Christmas day!

Gerni is the go, bronze pump, good quality fittings etc. cheaper ones have either plastic pumps which warp with the heat and use or diecast which corrode and wear.

Another vote for Gerni, I had a Karcher that after limited use (but outside warranty) would not stop cycling on and off. Repair shop said it was cheaper to by a new one than fix.

supercheap superworks - $150.00 and a 2year replacement guarantee - had mine for three trying to kill on jobs, cars, boats, pool, house - keeps living. The brother in law also has one with nil complaints.

I've got a petrol 4stroke powered unit- big flow rate, super powerful, changeable spray patterns and heaps cheaper than comparable electric unit. Plus safety of no electricity near water!

Hi Junior,

Your petrol unit sounds the way to go. Can you let me know what make etc. and where you got it. My son had a Karcher, repaired once under warranty then blew its top as soon as it was out of warranty. Not worth repairing.

cheers, John L.

You may not like the sound of this... it's a Karcher!!!
Good unit though- uses a Honda motor. Mine gets used a lot and no problems in the last year that I've had it.
Karcher model- G 2400 HH
2400 PSI
9.5 Litres Per Minute
5 HP Honda 4 stroke
I bought mine at 'Total Tools Industrial' outlet.
There are other versions of the same concept available on ebay and at Repco etc.

Johnotoo,

I have used Gerni and can't knock the product. However when I went shopping I was a little put off by the price and availability out here in the bush. I ended up with a Stihl. It has the all bronze, 3 stage pump and goes pretty well. It was significantly cheaper than the Gerni.

I have had it for about 3 years now and never had a problem. Actually I do have one small problem. The nozzle which has the loose ball bearing in it plays up. That is caused by the high salt content in our water and I have been assured that it will clear up when and if the water quality improves. I fix it with a quick spray of WD40 before and after use.

Mine runs about the 2000psi and about 9l of water per min. It does the job adequately.

For really sticky stuff or large areas I use the work truck. It is only about 3500kpa but at 57 l per second it really shifts dirt. Sometimes it shifts the pavers, whoops!

Go the gerni, ours has been going for over 15 years, just got to watch the paint on old cars and EO stickers (other stickers too). paint on plastic panels can be a bit vulnerable too at times but not if you're careful.

I have a Karcher 2.91 ,

I just used it for 3 full days cleaning old pavers and they look like new ,it hasnt missed a beat , it doesnt have a metal spray head , I am not usually given to throwing my tools around the place.

It came with 3 heads , Power head : blasts dirt , Variable power head : adjustable pressure , Car wash brush .

No problems, kicks ass !

Just dont buy the smallest unit and expect the earth of it .

one word "GURNI" 16 years old & still going well .(heavy workshop use ) had more problems with the Honda driving the unit than the gurni itself (even that is not a lot but when some apprentice runs it out of oil i guess its to be expected lol)

Hi Johnnotoo,
Well it looks like the Gerni has got the nod so far....

One thing i will say is that get one that stands up and has wheels. Apart from being easier to move around, they usually have hooks you can roll up the hose onto.
We have a Karcher, it has no wheels and as such after lending it to friends many years ago, they dragged it around by the gun and this has left a crack in the body of the pump(plastic). This has happened twice now and cost around $80-$90 to fix the first time (part only). We will not be fixing it this time, as it will be replaced by a bigger and better unit.

Cheers Greg
