Choosing between the Bissell Little Green 1400B and the Proheat comes down to trading 11 ounces of tank capacity for an internal water heater. The standard 1400B gives you a 48-ounce clean water tank that easily handles a full sectional sofa without a refill. The Proheat drops to a 37-ounce capacity to fit Bissell’s HeatWave technology, which maintains hot tap water temperatures to break down dried pet urine and set-in coffee stains. If you deal with biological messes, the Proheat’s heated cleaning and included HydroRinse hose-flushing tool justify the upgrade. For occasional fresh spills on car seats or rugs, the 1400B offers better capacity for less money.

Design & Build Quality
The standard 1400B relies on basic, lightweight plastics that make it easy to carry up a flight of stairs without straining your wrist. The Proheat upgrades the ergonomics with a contoured handle design that prevents hand cramping during long upholstery cleaning sessions. Both extractors share a common weak point: the corrugated plastic hose and its connection joint. The plastic retaining clips at the base of the hose are prone to snapping if you pull the machine by the handle rather than lifting it.
Features & Performance
The 1400B holds 48 ounces of clean water, giving you enough runtime to extract an entire three-seat couch without stopping to refill. The Proheat drops the tank size to 37 ounces to make room for its internal heater. This component does not actually heat cold water; it maintains the temperature of hot tap water while you work. Keeping the water at a high temperature makes a massive difference when extracting dried pet vomit or old coffee stains from carpet fibers. The Proheat also includes a HydroRinse tool. You plug it into the hose nozzle to flush out trapped dirt and pet hair before storing the unit, preventing odors from developing inside the tubing.
Tank Capacity vs. Portability
When evaluating portable extractors, look at the clean water tank volume. A 48-ounce tank lets you clean a standard vehicle interior or a large area rug without stopping. However, larger tanks increase the machine’s footprint and filled weight. If you live in a multi-story home, a smaller 37-ounce unit is easier to carry up stairs. Always check the dirty water tank capacity as well; most machines require emptying the recovery tank before the clean water runs out to prevent the float valve from shutting off suction.
Water Temperature Maintenance
Portable spot cleaners rarely have the wattage to heat cold water to extraction temperatures. Instead, look for models with temperature maintenance technology. These systems use a small internal heating element to keep hot tap water warm throughout your cleaning session. Hot water lowers the surface tension of the cleaning formula, allowing it to penetrate carpet padding and break down enzymatic stains like pet urine much faster than room-temperature water. If you only clean fresh, liquid spills, this feature is unnecessary.
Hose Maintenance Tools
The corrugated hoses on portable spot cleaners trap dirt, dirty water, and pet hair in their ridges. If left uncleaned, this debris breeds bacteria and creates severe odors. Look for extractors that include a dedicated hose-flushing attachment. These tools cap the end of the nozzle and force clean water backward through the hose directly into the recovery tank. Without this tool, you have to manually suck up clean water from a bowl to rinse the hose, which is messy and less effective.
Frequently Asked Questions
Can I use regular laundry detergent in a Bissell Little Green?
No. Standard laundry detergents create excessive suds that will bypass the float valve and enter the vacuum motor, potentially destroying the machine. Only use non-foaming extraction formulas specifically designed for portable carpet cleaners.
Do I need to use hot water in the 1400B?
You should fill the clean water tank with hot tap water to improve cleaning performance. However, because the 1400B lacks a heating element, the water will cool down to room temperature within 15 to 20 minutes.
Conclusion: Our Final Verdict
Buy the Proheat if you regularly extract dried pet messes; the temperature maintenance and hose-flushing tool are essential. Choose the 1400B for fresh, occasional spills. Check the current prices below and pick the model that fits your household.
