10 Best Steam Cleaner For Cars 2026 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 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.

The McCulloch MC1270 Portable Power Steam Cleaner offers a strong option for those wanting a chemical-free way to deep clean cars as well as various home surfaces. It heats up quickly in about 5 minutes, providing up to 30 minutes of steam from its 25-ounce water tank, which is a decent runtime for detailed cleaning sessions without frequent refills. The steam output is adjustable and features a lockable trigger, allowing for continuous steam release which helps when tackling tough dirt or hard-to-reach spots in your car’s interior.

Weighing just over 4.5 pounds, this steam cleaner is quite portable and includes a shoulder strap plus a long power cord and hose, making it easy to maneuver around your vehicle or house. With 16 accessories ranging from brushes to a mop head, it is versatile enough for cleaning tile, grout, upholstery, and car detailing jobs like seats and dashboards. While the water tank size is adequate, it may not be ideal for very large or continuous jobs due to the 30-minute limit per fill.

Its handheld form factor and included attachments make it beginner-friendly, though users looking for a lightweight solution might find it a bit bulky compared to smaller handheld steamers. This cleaner suits car owners who want a multi-use, chemical-free cleaner that balances power, runtime, and accessory variety, but those needing extremely high steam pressure or longer uninterrupted use might want to consider other options.
