10 Best Steam Cleaner For Cars 2025 in the United States

The BISSELL Little Green Mini is a lightweight (7 pounds), portable carpet and upholstery cleaner designed for small stains and general deep cleaning, including car interiors. It excels in spot cleaning with its 4-inch Tough Stain Tool and HydroRinse self-cleaning feature, making it handy for removing dirt, pet stains, and allergens in tight spaces. Its 16-ounce water tank and corded electric power source allow for continuous use without needing battery swaps.

This model does not use steam for cleaning, so it lacks steam pressure, heating time, and on-demand steam control that are typical in steam cleaners for cars. If you’re specifically looking for steam cleaning to sanitize and loosen grime with heat, this product won’t meet that need. However, if you want a straightforward, convenient cleaner that can handle upholstery and carpet stains inside your car or home, it’s a solid choice.

Its compact size is great for easy storage and portability, though it may require some effort to clean larger areas due to the smaller water capacity. The BISSELL Little Green Mini is best suited for users needing a compact, effective stain remover rather than a steam cleaner for deep sanitizing.

The Hoover PowerScrub Deluxe Carpet Cleaner is designed primarily for deep cleaning carpets and upholstery. It uses rotating brushes and heated suction to remove tough stains and dries faster than many similar machines. It includes useful tools such as a pet stain cleaner, upholstery scrubber, and crevice tool, which can be helpful for cleaning car interiors, although it does not produce steam, a feature often favored for sanitizing and loosening dirt in automotive cleaning.

The machine features a water tank capacity of about 3.8 liters, allowing for longer cleaning sessions before needing to refill. It weighs 18.5 pounds and is corded, which may limit portability and maneuverability in tight car spaces. Its dual tank system separates clean and dirty water, making operation cleaner and easier.

While it lacks steam pressure and does not provide on-demand or continuous steam, it offers strong scrubbing power and useful attachments for removing stains from fabric surfaces. For those prioritizing stain removal without requiring steam, this model is effective. However, for steam cleaning or detailed sanitizing of car interiors, a dedicated steam cleaner would be more appropriate.

The BISSELL Little Green Max Pet Portable Cleaner is a powerful, easy-to-use option for cleaning car interiors, especially if you deal with pet messes. It offers strong suction that’s 30% more powerful than many similar portable cleaners, which helps remove stains, dirt, and pet hair effectively. The cleaner includes useful attachments like a self-cleaning tough stain tool and a pet hair removal tool, making it versatile for tackling different types of messes inside your car. It uses a two-tank system to keep clean and dirty water separate, which simplifies refilling and emptying.

Weighing just over 8 pounds, it’s reasonably portable but may feel a little heavy for some users during extended cleaning sessions. The product excels in suction and stain removal; however, it is not a traditional steam cleaner and does not produce steam or have a heating element, so it won't sanitize surfaces through heat. This model is best suited for those who want a deep cleaner for upholstery and carpets in cars, especially pet owners, and is less appropriate if you specifically want steam cleaning for sanitizing or chemical-free cleaning.

This makes the BISSELL Little Green Max Pet a solid choice for effective deep cleaning and stain removal inside cars, while lacking steam cleaning features.
