By Owen PalmerA Bissell Big Green carpet cleaner is a portable-style deep cleaner built around a large tank, a powerful suction system, and a rotating brush that loosens soil from carpet fibers. Used correctly, it can lift embedded dirt, pet odors and everyday traffic grime from wall-to-wall carpet and area rugs. This guide walks through setup, cleaning technique, drying and maintenance so you can get consistent results without soaking your floors or damaging the machine.
What the Big Green Carpet Cleaner Does Well
The Big Green line is best known for handling larger rooms and high-traffic areas. Its tank capacity means fewer refills, and its suction removes most of the water and dissolved dirt after each pass. Owners often report that it performs best on synthetic and nylon carpets that tolerate moisture well, and on low-to-medium pile fibers where the brush can reach the base of the carpet.
It is less suited to delicate natural-fiber rugs, very old carpet with loose backing, or floors that stay damp for long periods. Check the care tag on any rug before cleaning. If the tag says “dry clean only,” skip wet extraction altogether.
Before You Start: Preparation Steps
Good results start before the machine comes out. Skipping prep is the most common reason people feel disappointed with their results.
- Vacuum the entire area thoroughly. Loose grit left behind will turn into mud when wet and can scratch fibers.
- Move small furniture, or place foil or plastic protectors under heavy pieces to prevent rust stains from metal feet.
- Pre-treat visible stains with an appropriate carpet cleaning solution and let it dwell for 5 to 10 minutes.
- Test the solution on a hidden spot, such as inside a closet, and wait for the carpet to dry before judging color and texture.
- Open windows or run a fan. Good airflow shortens drying time significantly.
Tools and Supplies You Will Need
- Bissell Big Green carpet cleaner, fully assembled and inspected
- Manufacturer-approved carpet cleaning solution
- Clean water for the tank, ideally room temperature
- A small spray bottle for pre-treating spots
- Clean microfiber towels for blotting edges and stains
- A rubber-tipped tool or old toothbrush for stubborn spots
- A squeegee or wet vacuum for tight corners, if needed
Step-by-Step: Cleaning Carpet With the Big Green
Work methodically and avoid rushing. The goal is thorough rinsing and extraction, not saturation.
Step 1: Fill the Tanks Correctly
Fill the clean water tank to the fill line, not above it. Add solution according to the label, usually a measured capful per tank. Too much detergent leaves residue that attracts dirt and can make carpet feel stiff. Too little leaves soil behind.
Step 2: Set the Machine for Your Carpet
Adjust any heat or settings to suit your fiber. If your carpet is synthetic and in good condition, standard settings usually work. For delicate wool blends, use the gentlest option and test first.
Step 3: Clean in Overlapping Passes
Push the machine slowly in straight lines, overlapping each pass by about 2 to 3 inches. Pause at heavily soiled spots, letting the brush and suction work for a few extra seconds. Pulling the machine backward without spraying can help release stubborn grime, then resume normal cleaning.
Step 4: Extract Thoroughly
Release the trigger on the upstroke or after each section so suction can pull moisture out. Repeat passes over the same area without adding more solution until the carpet feels only slightly damp. Empty the dirty tank before it reaches the max line.
Step 5: Rinse With Clean Water if Needed
If the carpet feels sticky or looks dull after drying, run a rinse pass using plain water. Sticky carpet resoils quickly, so rinsing is worth the extra few minutes.
Drying Your Carpet Properly
Drying matters as much as cleaning. Carpet that stays wet for more than 24 hours can develop odors and mildew, and the backing may separate from the pad.
| Drying Factor | Recommended Approach |
|---|---|
| Airflow | Run fans pointed across the carpet, not at it |
| Foot traffic | Keep people and pets off until fully dry |
| Humidity | Use a dehumidifier if the room feels damp |
| Expected drying time | Often several hours, longer in humid weather |
| Test for dryness | Press a dry paper towel firmly on the carpet |
Handling Pet Stains and Odors
Pet accidents need a slightly different approach. Urine residue binds to fibers and padding, and surface cleaning alone rarely removes the source of the smell. Blot fresh accidents first, then pre-treat with an enzyme-based cleaner designed for pet odors before using the machine. Enzymatic products break down the organic compounds that cause odor. For more on this, see Bissell Carpet Cleaner for Pets: How to Choose and Use One Well and Bissell Animal Carpet Cleaner: How to Use One for Pet Stains and Odors.
If odor persists after cleaning, the padding may be contaminated. In that case, consult a professional carpet cleaner or flooring specialist for advice on pad replacement.
Comparing Models Before You Buy or Use
Not every Big Green-branded machine has the same features, so check which model you own.

Common Mistakes to Avoid
- Overwetting the carpet. More solution does not mean cleaner carpet, and it prolongs drying time.
- Skipping pre-vacuuming, which turns loose dirt into a muddy film.
- Using household detergents instead of approved solutions, which can leave sticky residue.
- Letting the dirty tank overflow, which can spread contamination back onto the carpet.
- Neglecting brush and hose cleaning, which reduces suction over time.
- Cleaning delicate rugs that are not rated for wet cleaning.
Tips for Better Results
- Clean high-traffic paths twice in separate passes rather than saturating them once.
- Empty and rinse both tanks immediately after use so odors do not build up.
- Check the brush roll for hair and debris before every session.
- Schedule deep cleaning every few months, and spot clean between sessions.

FAQ
Can I use the Big Green carpet cleaner on all types of carpet?
Most synthetic carpets handle it well. Natural fibers like wool and some delicate rugs may be damaged by heat or excess moisture, so check the manufacturer guidance and the care label first.
How much solution should I use per tank?
Follow the label on your solution bottle. Using more than recommended usually leaves sticky residue rather than cleaner carpet.
How long does carpet take to dry after cleaning?
Drying often takes several hours, and longer in humid conditions. Using fans and keeping foot traffic off the carpet speeds the process.
Why does my carpet feel sticky after cleaning?
Sticky carpet usually means leftover detergent. Run a rinse pass with clean water and extract thoroughly.
Can I clean pet urine stains with the machine alone?
Machine cleaning helps, but pre-treating with an enzyme cleaner is usually needed to remove the source of odor.
How often should I clean my carpet with this machine?
Many households do well with deep cleaning every few months, plus spot cleaning as needed. Homes with pets or heavy foot traffic may need more frequent sessions.
What if my carpet still smells after drying?
Persistent odor may mean the padding is contaminated. Consult a professional carpet cleaner or flooring specialist for guidance.
Is it safe to use the machine around children and pets?
Keep children and pets away from the area while the machine is running and until the carpet is fully dry. Store solutions out of reach.
Conclusion
A Bissell Big Green carpet cleaner can deliver strong results when you prepare the room, use the right solution, clean in overlapping passes, and dry the carpet thoroughly. Focus on extraction rather than saturation, and treat pet stains with an enzyme cleaner first. With regular maintenance and realistic expectations for your carpet type, the machine can keep floors looking and smelling fresh between professional cleanings.
