This is probably the cheapest carpet cleaner in the market, if you want a light weight powerbrush shampoorer that has good reviews.

At the end of the day, there are not many options of carpet shampoorer in the land down under. I was considering Bissell ReadyClean (20W7F, sold at $279 at major stores or $239 at David Jones), until I found this one in Bing Lee.
This model appears to be the previous generation of Bissell ReadyClean Powerbrush. The only difference is probably the handle: the ReadyClean handle can be retracted. Other than this, almost the same configuration. The same model (Bissell 2080) was sold at ~US $100 from Amazon a while ago, and reviews are also very positive

With over $100 difference, it is a no brainer for me. After using it for two or three times, I am very satisfied with the performance. The only drawbacks are the small tanks and no upholstery hose. But I can live with that.
Whats the performance like compared to the machines hired at woolies etc.
