I went down to Kmart to have a look at the pressure cleaner today, the have it ticketed for $79 but scanned at $59! Makes for a very cheap cleaning tool! They also have accessories available at clearance prices; patio brush attachment - $15, and two different types of brush attachments for $5-6. I couldn't resist so I bought one and a patio cleaner. Got it home and tested it, and the results were great! I mainly got it for cleaning my dirt bike which it did an excellent job of, it also has a detergent reservoir which mixes well, and the pressure is more than ample! It also has a 5 metre hose which I know is a major selling point for these devices. Only drawback is it doesn't have any storage oles for the handle or shaft, but that's a small issue and for the price it's nothing.
I don't know how long it's at that price for but worth considering if your not sure what to get or just need a cheap replacement.
Not recommended to use on bikes.
Personally I'd rather spend a little more on a branded product.
