BISSELL Little Green 1400B vs Max Pet SmartMix, Compared: Max lightens carrying and measures formula, while 1400B stretches fills

Quick verdict

A larger clean tank and manual solution control favor Little Green 1400B. Lighter carrying and automatic formula dosing favor Max Pet SmartMix.

Before you buy

Why, and what it costs you

Put tank capacities in the same units

Clean-liquid capacity is 0.38 US gallon for Little Green and 0.25 for Little Green Max Pet SmartMix. The gap between them is 16 fluid ounces, before recovery-tank limits come into play.

Where this comes from

128 US fluid ounces =1 US gallon. The capacities on record are 48 and 32 fl oz. Converting puts tank volume on one scale and says nothing about cleaning coverage.

The catch

BISSELL Little Green

With such a short attachment hose, you end up repositioning the body around a sofa or vehicle.

The catch

BISSELL Little Green Max Pet SmartMix

A large sectional is too much for the 32-ounce tanks, which suit spot work.

In practice

Differences you will notice

Put tank capacities in the same units

Clean-liquid capacity is 0.38 US gallon for Little Green and 0.25 for Little Green Max Pet SmartMix. The gap between them is 16 fluid ounces, before recovery-tank limits come into play.

How we worked this out

128 US fluid ounces =1 US gallon. The capacities on record are 48 and 32 fl oz. Converting puts tank volume on one scale and says nothing about cleaning coverage.

Factor in the water before you lift

Filling the clean tank puts roughly 3.13 pounds of water weight on Little Green and 2.08 pounds on Little Green Max Pet SmartMix. Follow the manual when you move and fill them.

How we worked this out

Approximate water mass = clean capacity in US gallons ×8.34 lb/gal. Inputs 48/128 and 32/128 gallons. The real total shifts with formula concentration, leftover dirty water and tools.

Max SmartMix is 1.45 pounds lighter, at a cost of 16 ounces of clean capacity

On the lighter Max the clean tank is 32 ounces, while the 1400B has 48 ounces.

How we worked this out

9.65 - 8.2 = 1.45 lb. 48 - 32 = 16 US fl oz. 16 / 48 × 100 = 33.3%, which is the drop in nominal clean volume.

Decision guide

How to decide

If you want a larger clean tank and to control the solution yourself, choose Little Green 1400B. If lighter carrying and automatic formula dosing come first, choose Max Pet SmartMix.

01

The original Little Green carries more clean liquid

Compared with the 32-ounce tank on the Max SmartMix, its 48-ounce tank is 50% larger. Longer spot work is where that counts, although your application technique decides the actual coverage.

02

SmartMix cuts weight and dosing effort

At 8.2 pounds, the Max is lighter than the 1400B at 9.65. Automatic dosing earns its keep when a quick setup matters more than getting the most out of each fill.

03

Check the exact tool pack

Accessories listed on the 1400B official page may differ from the Amazon carton. Verify the rinse and stain tools in the package you pick instead of assuming that every Little Green bundle is identical.

Check these before you buy

  • Verify the exact model and package contents on Amazon before you order.
  • Don't assume all Little Green bundles match. The official 1400B page and the Amazon carton can list different accessories, so confirm the rinse and stain tools in the selected package.

What this page can’t tell you

  • These conclusions are drawn from published specifications and the stated calculations. No hands-on performance test stands behind them.
