The catch
BISSELL Little Green Mini
The 16 oz clean tank and 13.5 oz recovery tank are far smaller.
Side by side
BISSELL Little Green Mini 4075 vs Max Pet SmartMix 38572, Compared: Dosing and rinse convenience come with Max, at 1.2 lb more empty carrying weight
Quick verdict
Little Green Mini 4075 is the pick for a seven-pound cleaner that deals with small, isolated spills. Max Pet SmartMix 38572 is the pick when larger tanks and automatic formula dosing will spare you repeated preparation. The Max is 1.2 lb heavier when empty and adds a dedicated water-only rinse mode.
Before you buy
Why, and what it costs you
Max has twice the clean capacity at 17% more empty weight
That trade pays off if your current spot jobs take several fills. It says nothing about how much floor each tank cleans.
Where this comes from
32 / 16 = 2. 1.2 / 7 × 100 = 17.1%, the added empty weight.
The catch
BISSELL Little Green Max Pet SmartMix
Empty, before any liquid, it is 1.2 lb heavier.

In practice
Differences you will notice
Max has twice the clean capacity at 17% more empty weight
That trade pays off if your current spot jobs take several fills. It says nothing about how much floor each tank cleans.
How we worked this out
32 / 16 = 2. 1.2 / 7 × 100 = 17.1%, the added empty weight.
Recovery capacity grows by even more
Max's 32 oz dirty tank is roughly 2.37 times the size of Mini's 13.5 oz tank. On a larger spot job, that can ease the pressure of stopping to empty it.
How we worked this out
32 / 13.5 = 2.37. The amount recovered depends on spray, fabric and extraction passes.
Under a strict eight-pound empty limit, Mini is chosen
Mini at 7 lb passes, and Max at 8.2 lb is over the limit by 0.2 lb. Either gains weight once filled, so the threshold has to say whether it means empty or ready-to-clean.
How we worked this out
8.2 - 8 = 0.2 lb. 7 ≤ 8 and 8.2 > 8. Only published empty weights are used.

Trade-offs
What each pick costs you
With BISSELL Little Green Mini
- SmartMix dosing and a dedicated rinse-mode selector are both missing.
With BISSELL Little Green Max Pet SmartMix
- Bigger tanks do not turn it into a push-along cleaner for whole rooms.
Change of plan
When the answer changes
The eight-pound empty-weight ceiling is firm
Go with BISSELL Little Green Mini. Only Mini comes in under that limit.
I need automatic mixing plus a clean capacity of 24 oz or more
Go with BISSELL Little Green Max Pet SmartMix. Both are covered by Max SmartMix.
For full rooms I need an upright cleaner
Neither model fits. Go with a whole-room carpet cleaner instead.
Decision guide
How to decide
For a seven-pound cleaner used on small, isolated spills, take Little Green Mini 4075. When larger tanks and automatic formula dosing will save you repeated preparation, take Max Pet SmartMix 38572. The Max weighs 1.2 lb more while empty and adds a dedicated water-only rinse mode.
Go by the typical spill and leave the largest possible job aside
Mini suits small seat spills or a short patch of carpet. As recurring messes get larger, Max's tank volume becomes worth more. Max still relies on a handheld cleaning tool, so repeated full-room passes aren't the main reason to choose either.
Empty weight and working weight are different things
The specifications make the 1.2 lb difference in body weight plain. More liquid means more to carry, though a larger tank does not need to be filled to the maximum for each small job. Work out whether your lifting limit applies to the dry machine or to a ready-to-use setup.
SmartMix is worth it when it changes your routine
Automatic dosing and the rinse selector come in handy when you go back and forth between cleaning and rinsing. If you only clean one small spill now and then, Mini's fill marks may already be simple enough. After use, both machines still need the dirty water disposed of and the parts dried.
