Carpet-machine rentals can cost up to $50 per day, so a 2-day rental can cost more than buying a Bissell Little Green outright. Plus, those machines are, well, huge.

Amazon has discounted the Bissell Little Green Pet Deluxe Carpet Cleaner to its cheapest price ever — but the markdown is only here for a limited time. Here's the super deal to shop before it's gone ...

Simply bust out your portable Little Green Pet Deluxe Carpet Cleaner, and make any mess a thing of the past, all for just $124.99 this week on Amazon.

I expected green companies to be higher priced than the highly rated traditional carpet cleaners I've used in the past, but they're not. Expect to pay $150 to $300 for most homes.
