When I look at the market for portable carpet cleaners for pets, one brand dominates the conversation for good reason: BISSELL. However, their lineup can feel confusingly similar. You might wonder if you need the Little Green Mini for its compact size or the Little Green Pet Deluxe for its larger tank. The core tradeoff here is between portability and capacity. Smaller units are easier to store and lift, but they require frequent refilling, which can be frustrating when dealing with multiple accidents. Larger units hold more solution but are heavier and bulkier to store in a closet.

More Details on Our Top Picks
BISSELL Little Green Max Pet SmartMix Portable Carpet Cleaner
This model stands out because it solves the most common pain point in portable cleaning: mixing solutions. The SmartMix Technology automatically blends water and formula, which means you do not need to measure doses precisely. This is a significant advantage over the standard Little Green models, where incorrect mixing can lead to either weak cleaning or excessive suds. In terms of power, it boasts 30% more suction than competitive portable deep cleaners, which translates to faster drying times and less residual moisture in your carpets. Compared to the Little Green Mini, this unit is bulkier but far more capable for serious stains.
However, the 8-ounce capacity is a notable drawback. While the mixing system is convenient, the small tank means you will likely need to refill it multiple times if you are cleaning a large area or dealing with multiple accidents. It is corded, so you are tethered to an outlet, but the hose length is sufficient for most room-sized tasks. This pick makes the most sense for owners who prioritize cleaning efficacy over maximum portability.
Pros:- SmartMix Technology eliminates manual measuring errors.
- 30% more powerful suction than standard competitors.
- Includes specialized PET PRO OXY formula for odors.
- Self-cleaning tools reduce maintenance effort.
Cons:- Small 8-ounce tank requires frequent refilling.
- Corded design limits movement across large rooms.
- Bulkier than the Mini or standard Little Green models.
Best for: Pet owners who want automated mixing and high suction power for tough stains.
Not ideal for: Users needing to clean large areas quickly without frequent refills.
- Brand:BISSELL
- Model Number:38572
- Item Weight:8.2 pounds
- Dimensions:8.3″D x 12″W x 11.5″H
- Capacity:8 ounces
- Power Source:Corded Electric
- Technology:SmartMix
- Suction Power:High (30% more than competitors)
Our verdict“The best choice for those who want powerful, hassle-free cleaning without worrying about solution ratios.”
BISSELL Little Green Pet Deluxe Portable Carpet Cleaner, 3353
If you struggle with the small tanks on other portable units, this model is your solution. The 48-ounce tank capacity is significantly larger than the Little Green Mini or the Max Pet SmartMix. This allows you to clean larger sections of carpet or upholstery without stopping to refill. For households with multiple pets or large dogs, this capacity is a practical necessity. The unit is still portable at 9.7 pounds, though it is noticeably heavier than the lighter models in this lineup. It includes a variety of tools, including a pet hair removal tool, which is more effective than the basic attachments on the standard Little Green.
Compared to the Little Green Pet Pro, the Deluxe offers a better balance of tank size and tool versatility. However, the larger footprint means it takes up more storage space. You will also need to manage a heavier machine when cleaning stairs or high surfaces. This option is better suited to those who have the storage room and physical strength to handle a larger unit but want to avoid the hassle of constant refilling.
Pros:- Large 48-ounce tank reduces refill frequency.
- Includes multiple specialized tools for versatile cleaning.
- Effective on pet stains, spots, and odors.
- Supports pet rescue efforts with proceeds.
Cons:- Heavier at 9.7 pounds compared to compact models.
- Bulky dimensions require more storage space.
- Corded power restricts mobility.
Best for: Owners of multiple pets or large breeds who need extended cleaning time.
Not ideal for: Those with limited storage space or difficulty lifting heavier appliances.
- Brand:BISSELL
- Model Number:3353
- Capacity:48 oz
- Weight:9.7 pounds
- Dimensions:11″D x 19.25″W x 13.38″H
- Power Source:Power Cord
- Primary Use:Pet Stains and Odors
- Tool Count:Multiple included
Our verdict“The ideal choice for busy pet households that need a bigger tank to handle frequent accidents.”
BISSELL Little Green Mini Portable Carpet Cleaner, 4075
This is the most compact and lightweight option in the lineup, weighing just 7 pounds. I recommend this model for apartment dwellers or those with limited closet space. Its small footprint makes it easy to store under a sink or in a cabinet. Despite its size, it remains effective on small, fresh stains. The self-cleaning hose is a valuable feature here, as it simplifies maintenance on a unit that might otherwise be difficult to clean thoroughly due to its small size. Compared to the Little Green Pet Deluxe, the Mini requires much more frequent refilling, but it wins on agility and ease of storage.
The 16-ounce capacity is a clear limitation. You will likely need to stop and refill after cleaning just one or two small spots. This makes it less suitable for deep cleaning large rugs or car seats. However, if your primary need is spot cleaning small accidents on upholstery or stairs, the Mini’s maneuverability is unmatched. It is corded, so plan your cleaning sessions around outlet availability. This pick makes the most sense for users who prioritize storage convenience over cleaning duration.
Pros:- Smallest footprint for easy storage.
- Lightweight design reduces arm fatigue.
- Self-cleaning hose simplifies maintenance.
- Ideal for cars and upholstery.
Cons:- Small 16-ounce tank requires frequent refilling.
- Not powerful enough for deep carpet stains.
- Corded limit on mobility.
Best for: Small apartments, car interiors, and spot cleaning small accidents.
Not ideal for: Large areas, deep carpet cleaning, or frequent heavy messes.
- Brand:BISSELL
- Model Number:4075
- Item Weight:7 pounds
- Dimensions:10″D x 13.5″W x 12.13″H
- Capacity:16 ounces
- Power Source:Corded Electric
- Color:Tea Green
- Tool Included:4″ Tough Stain Tool
Our verdict“The best choice for those with limited storage who only need to handle small, occasional spills.”
BISSELL Little Green Max Pet Portable Carpet & Upholstery Cleaner
The Little Green Max Pet sits comfortably in the middle of the lineup, offering powerful suction and a robust build. It is designed specifically for soft surfaces, making it excellent for sofas, mattresses, and thick rugs. The self-cleaning stain tool is a standout feature, reducing the time spent rinsing attachments after use. Compared to the SmartMix version, this model requires manual mixing, which adds a step to the process. However, it offers similar suction power and weight, making it a solid alternative if you do not want to pay extra for the SmartMix technology.
With a capacity listed as 2 pounds (which correlates to a moderate tank size), it handles more than the Mini but less than the Deluxe. The main drawback is its specialization; it is not suitable for hard floors. If you need a versatile cleaner for tile or wood, this is not the right pick. It is best for owners who focus exclusively on fabric and carpet cleaning and want a balance between power and size.
Pros:- Strong suction for deep fabric cleaning.
- Self-cleaning stain tool for easy maintenance.
- Lightweight despite powerful performance.
- Specialized pet formulas included.
Cons:- Not suitable for hard floors.
- Manual mixing required unlike SmartMix models.
- Corded operation restricts movement.
Best for: Owners focusing on deep cleaning sofas, mattresses, and thick rugs.
Not ideal for: Users needing to clean hard floors or large carpeted areas quickly.
- Weight:8.2 pounds
- Dimensions:8.3″D x 12″W x 11.5″H
- Capacity:2 pounds
- Power Source:Corded Electric
- Surface Type:Soft Surfaces Only
- Feature:Self-Cleaning Tool
- Brand:BISSELL
- Model:Little Green Max Pet
Our verdict“A powerful option for fabric-specific cleaning that balances size and suction effectively.”
BISSELL Little Green Pet Pro Portable Carpet Cleaner, 3909
This model is often the most affordable entry into the Little Green Pet line. It provides strong suction and includes a crevice tool and pet hair removal tool, which are essential for getting into tight spaces around baseboards and furniture legs. Compared to the Deluxe, the Pet Pro has a smaller tank capacity (8 ounces), meaning you will need to refill it more often. However, for owners with only one small pet, this limitation may not be a significant issue. It is a straightforward machine that gets the job done without the advanced mixing features of the SmartMix.
The tradeoff here is clearly convenience versus cost. You save money upfront, but you spend more time refilling and mixing. It is corded and lightweight, making it easy to move around. This pick makes the most sense for budget-conscious buyers who do not have heavy cleaning demands. If you have multiple pets or large stains, you might find the frequent refilling frustrating, but for occasional spot cleaning, it is a reliable workhorse.
Pros:- Cost-effective entry-level model.
- Includes crevice and pet hair tools.
- Strong suction for its size.
- Lightweight and easy to store.
Cons:- Very small 8-ounce tank capacity.
- Requires frequent refilling for larger jobs.
- Basic feature set compared to Deluxe or SmartMix.
Best for: Budget-conscious owners with one small pet and occasional accidents.
Not ideal for: Households with multiple pets or large stains requiring long cleaning sessions.
- Brand:BISSELL
- Model Number:3909
- Capacity:8 ounces
- Power Source:Corded
- Color:Green
- Included Tools:Crevice, Pet Hair, Stain Tool
- Unit Count:1
- Primary Use:Pet Stains
How We Picked
I evaluated these portable carpet cleaners based on three specific criteria relevant to pet owners: suction strength, ease of use, and cleaning efficiency. Suction is critical because pet stains often penetrate deep into carpet fibers. I looked for models that offer strong extraction to pull dirty water back out, preventing residue buildup. Ease of use was assessed by looking at tank capacity relative to weight. A heavy machine is difficult to maneuver if it is also awkwardly shaped. I also considered the maintenance requirements, specifically whether the tools are self-cleaning or if they require manual disassembly. Finally, I judged each unit on its ability to target pet-specific issues, such as hair removal and odor elimination, rather than just general dirt.

Factors to Consider When Choosing Portable Carpet Cleaner For Pets
Choosing the right portable cleaner depends on how often you clean and how much space you have. I break down the key factors to help you narrow down your decision.
Tank Capacity vs. Portability
This is the primary tradeoff in this category. Small tanks (like the Mini’s 16 oz) mean the unit is light and easy to store, but you will stop frequently to refill. Large tanks (like the Deluxe’s 48 oz) allow for longer cleaning sessions but result in a heavier, bulkier machine. If you have one small cat, a small tank is likely sufficient. If you have two large dogs, a larger tank saves you time and frustration.
Suction Power and Drying Time
Strong suction is not just about removing stains; it is about extracting water. Models with higher suction, such as the Max Pet SmartMix, pull more moisture out of the carpet. This reduces drying time, which is critical in homes with pets who might track water around or develop mold issues in damp carpets. Cheaper models may leave carpets wetter for longer, requiring fans or open windows to dry.
Maintenance and Ease of Cleaning
Look for self-cleaning tools. Portable cleaners get dirty quickly. Units like the Little Green Mini and Max Pet include self-cleaning hoses or tools, which prevent clogs and odors in the machine itself. Models without this feature require manual disassembly and rinsing, which can be messy and time-consuming. If you dislike maintenance, prioritize models with self-cleaning capabilities.
Frequently Asked Questions
Can I use these portable cleaners on hard floors?
Most of the models reviewed here, including the Little Green Pet Deluxe and Max Pet, are designed specifically for soft surfaces like carpets, upholstery, and rugs. Using them on hard floors can result in excessive water pooling, which may damage wood or laminate. If you need to clean hard floors, you should look for a dedicated steam mop or a wet/dry vacuum, as these portable spot cleaners lack the suction and pad design required for safe hard floor cleaning.
Do I need to buy special pet formulas?
While you can technically use generic carpet cleaners, specialized pet formulas are highly recommended. These formulas contain enzymes that break down organic proteins found in urine and feces, which generic cleaners often miss. Many of the models in this roundup, such as the Max Pet SmartMix, come with trial sizes of these specialized formulas. Using them ensures better odor elimination and reduces the chance of pets re-marking the cleaned area.
Are these cleaners cordless?
No, all five models in this comparison are corded. This is a common limitation in the portable carpet cleaner market at this price point. The cord provides consistent power for strong suction, which is necessary for deep cleaning. The downside is that your range is limited by the length of the power cord and the availability of outlets. You may need to use an extension cord or move between rooms to clean different areas.
How often should I clean the machine itself?
You should clean the machine after every use. Pet stains leave behind residue and hair that can clog the suction channels and cause bad odors. Models with self-cleaning tools, like the Little Green Mini, make this process easier by flushing the hose automatically. For models without this feature, you must manually rinse the tanks and tools with clean water after each session to maintain hygiene and performance.
Which model is best for car interiors?
The BISSELL Little Green Mini is the best choice for car interiors due to its compact size and lightweight design. It is easy to maneuver in tight spaces like car seats and footwells. However, if you have large SUVs or trucks with extensive carpeting, the Little Green Pet Deluxe might be better simply because its larger tank reduces the number of refills you need to carry into and out of the vehicle.
Conclusion
Choosing the right portable carpet cleaner for pets comes down to balancing your space constraints with your cleaning volume. If you want the most convenient experience with automated mixing, I recommend the BISSELL Little Green Max Pet SmartMix. For those with limited storage and small messes, the Little Green Mini is the most practical choice. If you have multiple pets and need to clean larger areas without constant refilling, the Little Green Pet Deluxe offers the best capacity. Evaluate your typical mess size and storage space, and choose the model that aligns with your daily routine rather than just the highest suction rating.
