What matters in practice
The differences that matter
Compare tank capacity in the same units
Little Green Pet Pro holds 0.5 US gallon of clean liquid and Little Green 0.38. The difference is 16 fluid ounces before considering recovery-tank limits.
How we reached this conclusion
128 US fluid ounces =1 US gallon. Recorded capacities 64 and 48 fl oz. This normalizes tank volume without predicting cleaning coverage.
Account for the water before lifting
A full clean tank adds roughly 4.17 pounds of water-equivalent weight to Little Green Pet Pro and 3.13 pounds to Little Green. Move and fill according to the manual.
How we reached this conclusion
Approximate water mass = clean capacity in US gallons ×8.34 lb/gal. Inputs 64/128 and 48/128 gallons. Formula concentration, residual dirty water and tools change the actual total.
Pet Pro adds one-third more clean capacity for 1.35 pounds more empty weight
Its 64-ounce tank is 33% larger than 1400B 48-ounce tank, with empty mass rising from 9.65 to 11 pounds.
How we reached this conclusion
(64 / 48 - 1) × 100 = 33.3%. 11 - 9.65 = 1.35 lb. Clean capacity does not establish cleaned-area coverage.

Meaningful differences
What changes the fit
| What changes | BISSELL Little Green Pet Pro | BISSELL Little Green | Why it matters |
|---|---|---|---|
| Machine type | Portable spot cleaner | Portable spot cleaner | A spot cleaner is not an efficient replacement for a whole-room upright. |
| Nominal clean tank | 64 US fl oz | 48 US fl oz | Capacity is not a promise of area coverage. |
| Empty weight | 11 lb | 9.65 lb | Water, tools and solution add weight. |
| Hose | 5 ft | Maker page conflicts between 4 and 4.5 ft | Check exact bundle contents and any conflicting model documentation. |
| Power cord | 15 ft | 15 ft | Outlet position affects usable reach. |
| Cleaning system | Manual formula mixing, pet and crevice tools | Manual solution mixing and hose extraction | Features do not establish a matched-test cleaning winner. |
What you give up
Every choice has a cost
If you choose BISSELL Little Green Pet Pro
- The portable head is inefficient for cleaning an entire carpeted room.
If you choose BISSELL Little Green
- Tool packs vary. The current official 1400B page lists HydroRinse, so verify the Amazon carton contents.
