Comparison: BISSELL Big Green Professional Carpet Cleaner vs. Rug Doctor Mighty Pro X3 Commercial Carpet Cleaner

In this comparison, we’ll explore key aspects such as performance, design, ease of use, and value to help you determine which carpet cleaner best fits your needs.

Performance and Cleaning Power

Both machines are designed to tackle tough stains, dirt, and odors, but they approach cleaning in slightly different ways.

BISSELL® Big Green® Professional Carpet Cleaner features a rotating DirtLifter PowerBrush that scrubs carpets while cleaning both forward and backward passes. This feature reduces cleaning time and allows for faster drying, which is especially useful when dealing with large areas. With a 12-amp motor, it provides significant power, but it does not have the same level of targeted stain treatment as the Rug Doctor model.

On the other hand, Rug Doctor Mighty Pro X3 Commercial Carpet Cleaner utilizes a one-pass cleaning system that combines spraying, scrubbing, and extracting in one efficient cycle. It also includes a triple-action vibrating brush that scrubs all sides of carpet fibers, making it particularly effective at loosening deeply embedded dirt, stains, and pet messes. The machine’s enhanced vacuum motor ensures powerful suction, which helps in quicker drying times and thorough extraction of dirt. This machine also comes with an additional Pet Carpet Cleaner Solution, which makes it highly efficient at removing pet-related stains and odors.

Capacity and Tank Design

The tank design is an important consideration when choosing a carpet cleaner, as it impacts the frequency of refills during cleaning sessions.

FeatureBISSELL® Big Green®Rug Doctor Mighty Pro X3
Tank Capacity1.75 gallons3.9 gallons
Recovery Tank Capacity1.75 gallons3.9 gallons
Number of Refills RequiredModerate (due to smaller tanks)Fewer (due to larger tanks)
Ease of Tank Filling/EmptyingEasy to fill and emptyEasy to fill and empty

The BISSELL® Big Green® has a 1.75-gallon capacity for both clean and dirty water tanks, which means users may need to refill and empty the tanks more often during extended cleaning sessions. However, the Rug Doctor Mighty Pro X3 offers a larger 3.9-gallon tank, allowing for longer cleaning time with fewer interruptions for refilling or emptying. This larger capacity is particularly advantageous for larger homes or commercial environments where continuous cleaning is required.

Ease of Use and Portability

While both machines are effective, they differ in terms of portability and ease of use.

The BISSELL® Big Green® weighs 42 pounds, which is relatively heavy but manageable due to its well-designed handle. It’s easy to maneuver thanks to its sturdy construction, but it can be a bit cumbersome for some users, especially in tight spaces or on stairs.

In contrast, the Rug Doctor Mighty Pro X3 weighs 47 pounds, making it even heavier than the BISSELL® model. Its large size and weight may be challenging for some users, especially when used over long cleaning sessions. However, it has large wheels that make it easier to roll around, even over rough surfaces. The handle also folds down for easy storage, though its bulky size could be an issue in small storage spaces.

Pet Stain and Odor Removal

Both machines are designed with pet owners in mind, but the Rug Doctor Mighty Pro X3 has the advantage of an included 48 oz. Pet Carpet Cleaner Solution. This solution helps neutralize pet odors and effectively removes pet-related stains, making the cleaner ideal for homes with animals.

The BISSELL® Big Green® does a great job of cleaning up general dirt and grime, but it lacks a dedicated pet stain solution. It can still be used to clean pet messes, but you would need to purchase additional cleaning formulas to target pet odors and stains specifically.

Price and Value for Money

Included AccessoriesPet Formula IncludedPet Formula Included
Warranty1-year Consumer Warranty1-year Consumer and Commercial Warranty
Performance vs. PriceGreat value for home useCommercial-grade performance, higher price

In terms of price, the BISSELL® Big Green® tends to be slightly more affordable, typically ranging from $400 to $500, which offers good value for homeowners looking for a reliable carpet cleaner. However, the Rug Doctor Mighty Pro X3 is slightly more expensive, often priced between $500 and $600, but this reflects its commercial-grade power and larger capacity. If you’re looking for a cleaner that can handle heavy-duty use, the Rug Doctor may be the better investment, while the BISSELL® is great for everyday household cleaning.

Conclusion

In conclusion, both the BISSELL® Big Green® Professional Carpet Cleaner and Rug Doctor Mighty Pro X3 Commercial Carpet Cleaner offer strong performance, but each excels in different areas. If you’re a homeowner looking for a reliable, easy-to-use machine that can handle typical household dirt and stains, the BISSELL® Big Green® is an excellent choice. It offers effective cleaning with a smaller tank capacity and a user-friendly design.

However, if you’re dealing with more severe stains, pet odors, or have larger areas to clean, the Rug Doctor Mighty Pro X3 provides superior power, a larger tank, and additional features like a vibrating brush for deep cleaning. It’s a better fit for commercial environments or households with heavy carpet usage. Ultimately, both are exceptional products, and your choice should depend on your specific needs and the size of the area you need to clean.
