BISSELL Little Green Pet Pro vs 1400B: 1400B lightens smaller spill jobs and Pet Pro adds tank and hose room

Quick verdict

A larger clean tank and a documented five-foot hose point to Pet Pro 3909. Lighter carrying for smaller spills and upholstery jobs points to Little Green 1400B.

Before you buy

Why, and what it costs you

Put tank capacities in the same units

Clean-liquid capacity is 0.5 US gallon for Little Green Pet Pro and 0.38 for Little Green. 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 64 and 48 fl oz. Converting puts tank volume on one scale and says nothing about cleaning coverage.

In practice

Differences you will notice

Put tank capacities in the same units

Clean-liquid capacity is 0.5 US gallon for Little Green Pet Pro and 0.38 for Little Green. 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 64 and 48 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 4.17 pounds of water weight on Little Green Pet Pro and 3.13 pounds on Little Green. 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 64/128 and 48/128 gallons. The real total shifts with formula concentration, leftover dirty water and tools.

Pet Pro gains one-third more clean capacity and 1.35 pounds of empty weight

The 64-ounce tank is 33% bigger than the 48-ounce tank on the 1400B, and empty weight goes from 9.65 to 11 pounds.

How we worked this out

(64 / 48 - 1) × 100 = 33.3%. 11 - 9.65 = 1.35 lb. Knowing the clean capacity does not tell you how much area gets cleaned.

Decision guide

How to decide

For a larger clean tank and a documented five-foot hose, choose Pet Pro 3909. For lighter carrying on smaller spills and upholstery jobs, choose Little Green 1400B.

01

Pet Pro is the portable with more capacity

Compared with the 1400B, its 64-ounce clean tank adds 16 ounces. The exact 3909 page documents a five-foot hose, and the selected package includes pet-focused tools.

02

Lifting the original machine is easier

At 9.65 pounds, the 1400B is lighter than the 3909 at 11. A lower carrying weight can count for more than tank size when the cleaner regularly changes floors.

03

Don't make up an exact hose advantage

BISSELL's documentation for the 1400B conflicts, with hose lengths between four and 4.5 feet. The five-foot figure for Pet Pro is clear, but the exact difference should stay a range until someone checks the carton.

Check these before you buy

  • Before ordering, check the exact model and what the Amazon package includes.
  • Hose length for the 1400B is documented inconsistently, between four and 4.5 feet. Pet Pro's five-foot figure is clear, so keep the difference as a range until the carton is checked.

What this page can’t tell you

  • These conclusions rely on published specifications and the stated calculations. No hands-on performance test was done.
