Was going to buy the spot cleaner (https://www.ozbargain.com.au/node/391081), but figured i could clean the whole carpet with this one.
No idea if it actually cleans better than a store rented cleaner, but it claims to do so.
from Amazon site:
Dual Dirtlifter Powerbrushes combined with Heatwave Technology work to remove dirt and stains from your carpet. Now you don't have to rent a deep cleaner from a store to refresh your carpets and it's easy to store at home. The Proheat 2x Revolution offers multiple cleaning modes to fit your needs. In deep clean mode, the Proheat 2x Revolution has unbeatable cleaning versus the leading rental machine*. When using express clean mode, your carpet dries in about an hour** So you don't have to stay off your floors all day long. Plus, the attached hose and tools make it easy to clean stairs, upholstery, and hard-to-reach areas.
Have one - great machine
