What matters in practice
The differences that matter
Compare tank capacity in the same units
SmartWash Pet Complete holds 1 US gallon of clean liquid and Big Green Professional Carpet Cleaner 1.75. The difference is 96 fluid ounces before considering recovery-tank limits.
How we reached this conclusion
128 US fluid ounces =1 US gallon. Recorded capacities 128 and 224 fl oz. This normalizes tank volume without predicting cleaning coverage.
Account for the water before lifting
A full clean tank adds roughly 8.34 pounds of water-equivalent weight to SmartWash Pet Complete and 14.59 pounds to Big Green Professional Carpet Cleaner. 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 128/128 and 224/128 gallons. Formula concentration, residual dirty water and tools change the actual total.

|---|---|---|---|
| Machine type | Upright | Upright | A spot cleaner is not an efficient replacement for a whole-room upright. |
| Nominal clean tank | 128 US fl oz | 224 US fl oz | Capacity is not a promise of area coverage. |
| Empty weight | 20.5 lb | 42 lb | Water, tools and solution add weight. |
| Hose | 8 ft | 9 ft | Check exact bundle contents and any conflicting model documentation. |
| Power cord | 22 ft | 25 ft | Outlet position affects usable reach. |
| Cleaning system | Automatic dosing and movement-based wet/dry operation | Eight-row brush, forward and backward cleaning | Features do not establish a matched-test cleaning winner. |
