Have looked at previous threads which are now a year old and one is locked so thought would start a new thread

 

I presently have an old, at least 10 year, Top Craft 2100w motor with O/P 1886psi (10-13MPa or 130 bar). Karcher Tauranga inform me they have a Karcher K5 motor in them with bespoke everything else. My problem is the 6mtr hose is about to go and the two wands (dirt blaster & variable wand) nylon seal bush has gone with the dirt blaster nylon ball bearing gone. So am in need of a replacement.

 

The requirement is for every six months or so to keep a non painted fence, which we like el natural, clean & treated. Also have a 40 x 4 mtr driveway to keep treated and clean. Plus to lend out to lalatives every so often.

 

So I am looking at two machines:

 

Ryobi RPW140SC $198 and the Karcher K3 Plus $199 on special, (not on their website) both from Bunnings. Am leaning towards the Ryobi at the moment as have been told that the karcher surface cleaner is not as robust as the Ryobi and that the Ryobi hose reel is great as opposed to manual curling the hose up over the Karcher hook.

 

Thoughts please

I've always found electric water blasters weak and inefficient. I hire a commercial petrol powered one once every year or two and get the jobs done in half the time. Our local hire place charges $70 for a day. Dont have to worry about maintenance either, or loaning to people and being returned damaged.

I have the k3 premium and it works great. There are couple variations of it. Get the one that is water cooled and comes with a 5 year warranty.

Only every 6 months? Hire a real one when you need it. Proper petrol one puts the domestic electric models to shame.

It seems somewhat weird that "K3" is used for three different products, in that the "Premium" sold by Mitre 10 looks totally different to the models sold at Bunnings - they have the $199 model, and then the $299 variation with the "home kit" (I find that deck cleaner works pretty well) which appear the same, but then the "Full Control and Home and Car Cleaner" model is different again!

 

And none of these seem quite the same set as the "K3 Full Control Home" that topped Consumer's test, but it appears to be a cut-down version of the last model linked to above from Bunnings (without the car-cleaning additions).

 

Has anyone got a good handle of the differences between the various models? Looking at Karcher's website, all variants of the K3 have the same primary specs, but there are certainly three different looking models (reflected in the different size measurements).

 

I had been planning on buying the $299 K3 with home kit, but if it's worth spending a bit more to get a better quality one I'd certainly look at that (and the car cleaning accessories would no doubt be useful), but I'm not sure if there are meaningful differences in terms of performance.

My search of Mitre 10's site only finds the $500 Premium model I linked to above, and another model at $329, both viewable at https://www.mitre10.co.nz/shop/search?text=Karcher%20k3&q=Karcher%20k3

Is that $500 model different to the one you've got?

With my research into this I found that Karcher has their main models; K2, K3, K5, K7. Then within those models are their sub models and these sub models can change by just one item including but limited to the PSI rating and boy is there a price difference. Personally I think this structure is a pricing rip off and a selling gimmick. Their spares are also quite pricey.

 

I agree that yes the Karcher seems to have the better motor but today I bought the above Ryobi RPW150G from Bunnings. Why, well on inspection I liked the overall metal vs nylon/plastic couplings of the Karcher. Karcher will not let you use any detergent products other than their own and you will void your warranty otherwise. The Ryobi handle assemble felt stronger and more robust. Their spares are not so pricey.

 

Of course only time will tell.

Yes maybe using the foam gun attachment but NOT via the inbuilt detergent tank.

Yep, that's my assumption, in that it's essentially deliberate obsfication; there could also be a desire to provide specific retailers with 'exclusive' models (I see some are advertised as such) - a big thing for Bunnings and Mitre 10 as it means no matching +15%.

Interesting to read this assessment, given the substantively different ratings from Consumer - 89 vs 67% as mentioned by another poster earlier in this thread. The specific comments on the Ryobi were "This model has OK cleaning performance. But it has a couple of ease-of-use bugbears: it's the loudest unit on test, and it's fairly heavy for a domestic waterblaster." I agree the hose winder looks a great idea, as I too have found Karchers always coil up.

 

The only other model recommended by Consumer is a Nilfisk - has anyone had experience with their units?
