Main trade-off
BISSELL Big Green Professional Carpet Cleaner
At 42 lb empty, it asks much more of you on stairs.
Head-to-head
Choose Big Green 86T3 for its larger clean-water tank and longer hose when the machine can stay on one floor. Choose PowerScrub XL Pet if carrying weight and automatic detergent mixing matter more. Hoover's wider path does not establish better stain removal.
Before you choose
Hoover is about 54% lighter while empty. Carrying either with water adds mass, so emptying before moving floors remains useful.
What this is based on
(42 - 19.15) / 42 × 100 = 54.4%. Empty-product specifications only.

Winner by situation
Big Green weighs 42 lb. Hoover weighs 19.15 lb.
The stated capacities are 1.75 and 1 gallon.
PowerScrub XL meters formula. Big Green uses a premixed tank.
Big Green lists nine feet. Hoover lists eight.
No matched carpet, humidity and pass-count drying test is available.
What matters in practice
Hoover is about 54% lighter while empty. Carrying either with water adds mass, so emptying before moving floors remains useful.
(42 - 19.15) / 42 × 100 = 54.4%. Empty-product specifications only.
Its extra 0.75 gallon equals 96 US fluid ounces. That reduces refill pressure on a large task, without telling us how much carpet each gallon cleans.
1.75 - 1 = 0.75 US gallon. 0.75 × 128 = 96 US fluid ounces.
Hoover's nominal path is 14.3% wider. Extra overlap, slower passes or a second treatment can erase that geometric advantage.
(12 - 10.5) / 10.5 × 100 = 14.3%. No time-per-room or stain-removal test is implied.

BISSELL, 86T3
A heavy upright extractor with large tanks, a long cord and a nine-foot attachment hose.

Hoover, FH68050
A wide upright with five SpinScrub brushes, larger tanks and an eight-foot attachment hose.
Meaningful differences
| What changes | BISSELL Big Green Professional Carpet Cleaner | Hoover PowerScrub XL Pet | Why it matters |
|---|---|---|---|
| Empty machine weight | 42 lb | 19.15 lb | Hoover removes 22.85 lb before water or formula is added. |
| Clean-water tank | 1.75 US gal | 1 US gal | Big Green holds 75% more clean liquid by rated volume. |
| Cleaning path | 10.5 in | 12 in | Hoover covers a wider nominal strip. Overlap and pass count still matter. |
| Hose and cord | 9 ft hose, 25 ft cord | 8 ft hose, 23 ft cord | Big Green adds one foot of hose reach and two feet of cord. |
| Formula handling | Premix in clean tank | Automatic detergent mixing with separate supply | Hoover changes preparation between water and formula tasks. |
| Drying assistance | Extraction passes | HeatForce airflow assistance | The feature difference does not prove a drying-time advantage in your carpet. |
What you give up
Recommendation switch
Choose Hoover PowerScrub XL Pet. Only PowerScrub XL meets that limit.
Choose BISSELL Big Green Professional Carpet Cleaner. Big Green meets the volume requirement.
Choose neither. Neither selected model has a steam mode.
What matters in practice
Big Green makes more sense when its storage and main cleaning area are on the same level. The empty weight difference becomes a recurring burden if you carry it upstairs. Tank capacity should not outweigh a lifting limit that makes the machine difficult to use safely.
Big Green's larger clean tank can extend a filling interval. Neither capacity figure proves room coverage because spray use changes with stain severity and technique. Recovery tanks also need monitoring, and dirty water must be emptied before storage.
Hoover's HeatForce is a documented feature, while actual drying depends on how much water reaches the carpet and how much is extracted. Use dry passes and the carpet maker's instructions. Neither machine is a steam cleaner, and neither justifies wet-cleaning a fabric that prohibits it.
