Which is better for pet stains on carpet?

For a single accident or a small area, the Little Green is quicker to grab and cheaper at $74.62. For repeated messes across a whole room, the ProHeat's heated cleaning and rotating brushes lift more embedded dirt.

Can the Little Green clean a whole room?

It can, but slowly. The 48 fl oz tank and spot tool mean many refills and passes. A full-room job is what the ProHeat's 1 gallon tank and 12-row brush roll are built for.

Is the ProHeat worth the extra $123?

Only if you have carpet wall to wall. If your messes are on stairs, sofas and car seats, the Little Green covers them for $74.62 at Walmart as of November 4, 2026.

Which is easier to use on stairs and in a car?

The Little Green. It is a portable canister you carry, while the ProHeat is a 7.9 kg upright with a 2.4 m hose that you balance on steps.

How fast does each one dry?

The ProHeat has an Express Mode that dries carpet in about 30 minutes. The Little Green has no fast-dry mode, so spot areas air dry on their own.

Do both use BISSELL formula?

Yes. Both ship with an 8 oz trial-size formula, and both take BISSELL carpet cleaning solutions.
