I've been watching this vac for a while and this is the cheapest I've seen (apart from costco at $150, but without the steam cleaner).
The reviews are pretty decent, just keep in mind that a cordless vac will never be as powerful as a mains-powered vac. Batteries will eventually die too.
This is for the latest 12V model with the LEDs on the front. The suction part is detachable for use as a standard cordless vac.
The steam cleaner is an Optim which Godfreys lists at $99 usually:

how good is a cordless vac for $169/$150?
