BISSELL Little Green Max Pet SmartMix Portable Carpet Cleaner
Best Overall
The BISSELL Little Green Max Pet SmartMix, model 38572, is the best fit here for households that clean pet stains more than occasionally. It is a corded portable carpet cleaner with separate 32-ounce clean and dirty tanks, an 8.2-pound body, and SmartMix technology that manages the water-and-formula mixture. It is designed for spot cleaning carpet, area rugs, stairs, pet beds, upholstery, and similar soft surfaces.
BISSELL advertises 30% more powerful suction than the Shark StainStriker and Dirt Devil Compact Spot Cleaner, based on a defined ASTM air-power test. That is a manufacturer comparison, not a guarantee that every stain will come out in one pass. The self-cleaning tough stain tool can help flush residue from the attachment after use, while the pet-hair tool is useful when loose hair is mixed into a mess.
Why You’ll Like It: It offers better capacity and continuous corded operation for several spots, furniture cushions, carpeted stairs, or vehicle seats.
Who Should Avoid It: Buyers who only need a tiny handheld cleaner for one quick spill may find it larger and less convenient than the cordless option.
Pros:
- SmartMix system reduces measuring and includes a water-only rinse mode.
- Separate 32-ounce clean and dirty tanks support longer spot-cleaning sessions.
- Designed for carpet, rugs, stairs, upholstery, pet beds, and auto interiors.
- Specialty tools help with stains, tool rinsing, and embedded pet hair.
Cons:
- Corded operation limits where you can work without moving to another outlet.
- At 8.2 pounds before adding water, it is heavier than a handheld cordless cleaner.
- It is a spot cleaner, not a full-width machine for deep-cleaning an entire room.
BISSELL Pet Stain Eraser Cordless Portable Carpet Cleaner
Best for Quick Cordless Cleanup
The BISSELL Pet Stain Eraser Cordless, model 20037, is made for small messes that need attention before they spread or dry. The handheld cleaner sprays solution, lets you scrub with the built-in brush, and suctions the dirty liquid into a separate tank. Its cordless design is convenient for carpeted stairs, pet beds, upholstery, and vehicle interiors.
The official specifications list a 7.2-volt rechargeable power system, about 15 minutes of run time, a four-hour charge time, an 8-ounce clean tank, and a weight of 4.6 pounds. That makes it portable, but the limited tank and battery are better for one or two spots than for a sofa, staircase, or several rooms in one session.
Why You’ll Like It: It can stay ready for a quick spill without dragging out a hose, cord, or larger machine.
Who Should Avoid It: Buyers with frequent set-in stains or several areas to clean at once will usually be better served by a corded portable cleaner.
Pros:
- Cordless handheld design is easy to carry around the home or vehicle.
- Spray, scrub, and suction functions are combined in one compact unit.
- Ready-to-use formula storage can shorten setup time for quick cleanup.
- BISSELL lists a two-year limited warranty for this model.
Cons:
- About 15 minutes of run time limits larger cleaning jobs.
- A four-hour charge is long compared with the available run time.
- The 8-ounce tank may need frequent refilling during repeated cleanup.
- The older model may have different seller, bundle, or availability details, so check the linked listing carefully.
BISSELL PET PRO OXY Spot & Stain Urine Eliminator Formula, 32 oz.
Best Compatible Formula Option
BISSELL PET PRO OXY Spot & Stain Urine Eliminator, product 2034, is a 32-ounce formula made for compatible BISSELL portable deep cleaners. It is designed for pet spots and odors on carpet, area rugs, stairs, upholstery, pet beds, and other approved soft surfaces. BISSELL also states that the formula meets EPA Safer Choice standards and is safe for use around children and pets when used as directed.
This bottle is not a standalone trigger spray or a carpet-cleaning machine. Follow the formula label and the exact cleaner manual because mixing directions can differ by machine. Some Pet Stain Eraser models are designed around ready-to-use solution, while larger portable deep cleaners use water and formula fill lines.
Why You’ll Like It: It adds a pet-focused OXY formula option for compatible portable machines and is intended to address both visible spots and lingering odors.
Who Should Avoid It: Do not buy it as a substitute for a cleaning machine, and do not use it in an upright or incompatible cleaner unless the manufacturer directions allow it.
Pros:
- Made for compatible BISSELL portable deep cleaners.
- Intended for common pet messes and odor cleanup on approved soft surfaces.
- Meets EPA Safer Choice standards.
- Safe around children and pets when used exactly as directed.
Cons:
- Requires a compatible portable cleaner for extraction-style cleaning.
- Mixing and filling instructions vary by machine model.
- Strong or old stains may need pretreatment or more than one cleaning pass.
- The fresh scent may not suit fragrance-sensitive households.
Factors to Consider When Choosing a BISSELL Pet Stain Cleaner
The right choice depends on the size and age of the mess, how often you clean, the surfaces involved, and whether portability or sustained suction matters more. A formula bottle and a cleaning machine solve different parts of the job, so compare them by role rather than treating them as direct substitutes.
Cleaning Job and Machine Type
Choose a corded portable deep cleaner when you regularly clean several pet spots, upholstery cushions, carpeted stairs, or vehicle seats. The larger tanks and continuous power reduce interruptions. Choose a cordless handheld model for a fresh, isolated spill where quick setup matters more than capacity. Buy cleaning formula only when you already own a compatible machine or are purchasing one at the same time.
Corded vs. Cordless
Corded models are usually the better fit for longer sessions because they do not stop for battery charging. Cordless models are easier to carry and use away from outlets, but run time and tank size limit how much you can clean. Do not compare motor voltage directly with suction performance because they measure different things.
Tank Capacity and Reach
A larger clean tank means fewer refills, while a larger dirty tank reduces stops for emptying. Hose length and cord length matter when cleaning stairs, sofas, and vehicles. Handheld cleaners remove the hose issue, but the full machine must be moved across the surface and held during use.
Formula Compatibility and Mixing
Use only formulas approved for the specific machine. Check whether the cleaner requires ready-to-use solution, a measured concentrate, or separate water and formula fill lines. Never assume that one BISSELL portable formula is prepared the same way in every model, and do not mix cleaning chemicals together.
Surface Care Labels
Before cleaning upholstery, check the fabric care tag. Water-based portable extraction is generally intended for fabrics marked W or WS, but the machine manual and furniture maker’s instructions take priority. Test a hidden area first for colorfastness, and avoid over-wetting cushions, seams, or backing materials.
Stain Age and Cleaning Technique
Fresh messes are usually easier to remove than old, set-in stains. Pick up solids first, blot excess liquid, apply only the recommended amount of solution, scrub without damaging the fibers, and make extra suction-only passes to pull out moisture. Repeatedly soaking the same area can slow drying and may push moisture deeper into the padding.
Cleanup and Maintenance
Empty and rinse dirty-water tanks after each use. Flush or rinse tools as directed, remove trapped hair, and allow tanks and attachments to dry before storage. Good maintenance helps control odors and keeps spray and suction paths from becoming blocked.
Warranty and Support
Warranty terms are model-specific. The Pet Stain Eraser 20037 is listed with a two-year limited warranty, while other machines may have different coverage. Check the exact model page, keep the receipt, and register the machine if the manufacturer provides that option. Formula bottles do not carry the same machine warranty considerations.
Frequently Asked Questions
How Long Does Carpet or Upholstery Take to Dry?
There is no single drying time. It depends on how much solution was applied, how many suction-only passes you made, the material, room temperature, and airflow. Use fans or ventilation and keep children and pets off the area until it is fully dry.
Can I Use These Cleaners on Upholstery and Furniture?
Use them only on surfaces approved by both the cleaner manual and the furniture care label. Many water-safe fabrics marked W or WS may be suitable, but delicate, dry-clean-only, leather, velvet, silk, or color-unstable materials may require another method. Test a hidden spot first.
Are BISSELL Cleaning Formulas Safe Around Pets and Children?
The PET PRO OXY formula is described by BISSELL as safe around children and pets when used as directed. Follow the label, use the correct dilution, store the bottle out of reach, do not mix it with other chemicals, and wait until the cleaned surface is dry before normal use.
What Is the Warranty Period?
It varies by model. The Pet Stain Eraser 20037 is listed with a two-year limited warranty, but you should verify the exact model and seller documentation before buying. Cleaning formula is a consumable product and should not be described as having the same warranty as a machine.
How Often Should I Use a Portable Pet Stain Cleaner?
Spot-clean pet accidents as soon as practical, following the carpet or upholstery care instructions. Whole-room deep-cleaning frequency depends on traffic, pets, fiber type, and the flooring manufacturer’s guidance. A portable cleaner is mainly intended for spots, stairs, upholstery, and smaller areas rather than routine full-room cleaning.
Conclusion
For the most capable all-around setup, choose the BISSELL Little Green Max Pet SmartMix. Its corded power, larger tanks, and specialty tools make it the strongest fit for recurring pet messes. Choose the Pet Stain Eraser Cordless when fast grab-and-go cleanup matters more than run time or capacity. Add the PET PRO OXY formula only as a compatible cleaning solution, and follow the exact machine and bottle directions.
Final recommendation
Most pet owners who expect repeated stains will get more useful cleaning range from the Little Green Max Pet SmartMix. The cordless model is the convenience pick for small fresh messes, while the formula is an add-on for compatible equipment rather than a replacement for a cleaner.
