10 Best Carpet Shampoos 2025 in the United States

The Zep All-Purpose Carpet Shampoo Concentrate Cleaner is a solid choice for anyone looking to tackle tough dirt and stains in carpets. Its professional-grade formula is designed to penetrate deep into carpet fibers, making it effective for various cleaning tasks, especially if you have a lot of ground-in dirt. One of its biggest advantages is its economical nature; the concentrated formula can produce up to 25 gallons of cleaning solution, which is excellent for those who require frequent cleaning or maintain large areas. Additionally, it is compatible with a wide range of carpet-cleaning machines, including popular brands like Bissell and Hoover, making it versatile for different users.

However, there are a few points to consider. The shampoo is unscented, which may not appeal to everyone, especially those who prefer a fresh fragrance after cleaning. Also, while it excels at stain removal, its effectiveness can vary based on the type of carpet and the nature of the stains. It's important to ensure compatibility with your specific carpet type, as some materials may react differently to certain cleaning formulas.

On the eco-friendliness front, while the product is recyclable, there is no specific information about its environmental impact, which may concern eco-conscious consumers. The Zep All-Purpose Carpet Shampoo Concentrate Cleaner is a powerful and economical option for users with heavy-duty carpet cleaning needs, but its unscented formula and lack of detailed eco-friendly certification may be drawbacks for some.

The Bissell PRO MAX Clean + Refresh with Febreze is a strong contender for those looking to maintain clean carpets, area rugs, and upholstery. Its powerful cleaning formula is designed to tackle dirt and odors effectively, making it especially suitable for heavily soiled areas and stubborn stains. The inclusion of Febreze adds a fresh scent to your cleaned spaces, which can be quite pleasant for users who enjoy a nice fragrance post-cleaning. Additionally, this shampoo is compatible with upright carpet cleaners, ensuring a deep clean across various surfaces.

One of the standout features is its eco-friendliness; the formula contains no heavy metals, phosphates, or dyes, and it uses biodegradable detergents. This makes it safer to use around kids and pets when used as directed. However, it's essential to note that this product is in liquid form, which requires careful handling to avoid spills. While it effectively cleans and refreshes, the fresh scent might be overpowering for some users. Also, as it’s specifically designed for use with machines, it may not be as effective for manual cleaning methods.

If you have a compatible carpet cleaner and are looking for an eco-friendly, powerful cleaning solution, the Bissell PRO MAX Clean + Refresh is a worthy option, particularly in homes with pets and children.

The BISSELL 2X Pet Stain & Odor Full Size Machine Formula is a powerful carpet shampoo designed for pet owners. Its cleaning power is notable, effectively tackling tough pet messes like urine, vomit, and dirt. The formula is safe for use on carpets, area rugs, and upholstery, making it versatile.

One of the strengths of this product is its eco-friendliness—free from heavy metals, phosphates, and dyes, and containing biodegradable detergents, it's a good choice for environmentally conscious consumers. Additionally, the shampoo is safe to use around kids and pets when used as directed, providing peace of mind for families. The fresh scent leaves carpets smelling clean, which is a nice touch after dealing with pet odors.

The formula is specifically made for upright carpet cleaners, which may limit its use for those who own different types of cleaning machines. The product's emphasis on pet stain and odor removal might make it less appealing to those without pets. The BISSELL 2X Pet Stain & Odor Full Size Machine Formula is a strong contender for pet owners seeking an effective, eco-friendly carpet shampoo, but may not be as versatile for households without pets or those using non-upright carpet cleaners.
