Bissell Little Green vs Hoover CleanSlate: Which Spot Cleaner is Best?

If you follow a strict house cleaning schedule, your hard floors are likely sparkling. You probably even have a robot vacuum handling the daily dust. But what happens when the dog tracks mud onto your favorite rug, or someone spills coffee on the living room sofa?
You can't put a couch cushion in the washing machine, and scrubbing by hand only pushes the stain deeper into the fabric.
Enter the Portable Carpet & Upholstery Cleaner. These compact machines spray a specialized cleaning formula deep into the fabric and immediately use powerful suction to extract the liquid, pulling the dirt out with it.
Right now, two machines are completely dominating the market: the incredibly viral Bissell Little Green Machine and the powerful Hoover CleanSlate. We put them head-to-head to see which one deserves a spot in your cleaning closet.

1. The Viral Classic: Bissell Little Green Machine
If you have spent any time on cleaning TikTok or Pinterest, you have seen the Bissell Little Green. It is an absolute powerhouse that has remained a bestseller for years, and for good reason.
Why It Wins (Tank Capacity & Simplicity): The Little Green holds a massive 48 ounces of clean water and formula. This means you can clean an entire armchair or a staircase without having to stop and run to the sink to refill it. It is also incredibly lightweight and easy to carry by the top handle.
The HydroRinse Tool: One of the grossest parts of older spot cleaners was the dirty water getting trapped in the ribbed hose. Bissell includes a "HydroRinse" attachment. When you are done cleaning your couch, you pop this tool on the end of the hose, and it flushes clean water entirely through the hose to wash it out before storage.
The Catch: The standard scrubbing brush is only 3 inches wide. While this is great for a small coffee spill, it takes a long time if you are trying to clean a large area rug or the entire backseat of your car.
The Verdict: The absolute best choice for quick, everyday spills and households that want a lightweight, easy-to-store machine.
2. The Power Upgrader: Hoover CleanSlate Pet
Hoover looked at everything people loved about the Bissell and decided to upgrade the tools and the suction power. If you have stubborn, set-in pet stains, the CleanSlate was built specifically for you.
Why It Wins (The Wide-Path Tool): Instead of a tiny 3-inch brush, the Hoover comes with a massive 7-inch WidePath tool. If you are cleaning carpeted stairs, car floor mats, or a large rug, the Hoover gets the job done in literally half the time it takes the Bissell.
Tight Spot Tool: It also includes a specialized crevice tool that shoots water and suctions from the very tip. It is perfect for getting deep down into the cracks of your sofa or the tight edges between your car seats where french fries and dirt accumulate.
The Catch: The clean water tank is slightly smaller (40 ounces), meaning you might have to refill it once during a heavy cleaning session.
The Verdict: The undisputed winner if you are dealing with heavy pet messes, dirty car interiors, or larger stains that require wider scrubbing tools.
Critical Decision Guide: Spot Cleaners vs. Upright Washers
1. Portable Spot Cleaners (Bissell Little Green / Hoover CleanSlate)
Best For: Couches, upholstered dining chairs, carpeted stairs, car interiors, and small pet accidents.
Pros: Lightweight, easy to store under the sink, very affordable.
Cons: You have to sit on the floor to use them. Too small to clean a whole room.
2. Full-Size Upright Washers
Best For: Deep cleaning entire carpeted bedrooms or massive area rugs.
Pros: You push them like a vacuum cleaner. Huge water tanks.
Cons: Heavy, expensive, and useless for cleaning couches or car seats. (If you are looking for a machine that vacuums and mops hard floors, see our Bissell Crosswave vs Tineco Review).
Final Verdict: Which One Should You Buy?
Buy the Bissell Little Green If:
You want the largest water tank so you don't have to pause and refill.
You want a tried-and-true, lightweight machine for quick coffee or wine spills.
You value the self-cleaning hose tool to keep the machine smelling fresh.
Buy the Hoover CleanSlate If:
You have pets that frequently have accidents on your rugs.
You want the 7-inch WidePath tool to clean large areas much faster.
You want the crevice tool to detail the interior of your car.

Frequently Asked Questions (FAQ)
Q: Do I have to use Bissell or Hoover formula in my spot cleaner?
A: While both manufacturers strongly recommend using their proprietary cleaning solutions to prevent motor damage and excessive foaming, many users successfully use a DIY mix. A popular, safe alternative is warm water with a tiny drop of clear liquid dish soap (like Dawn) or a splash of white vinegar. Never use bleach or heavy laundry detergent, as it will ruin the machine's seals.
Q: Does the Bissell Little Green Machine heat the water?
A: No. Neither the standard Bissell Little Green (1400B) nor the Hoover CleanSlate features an internal water heater. To get the best stain-removing power, you must fill the clean water tank with hot (but not boiling) tap water directly from your sink before you start cleaning. (Note: Bissell does make a "ProHeat" version of the Little Green, but it costs significantly more).
Q: How long does a couch take to dry after using a portable carpet cleaner?
A: Both the Bissell and Hoover feature powerful suction to extract the water they spray. If you use the proper technique (one wet spray pass, followed by multiple dry suction passes), your couch or car seats should only feel slightly damp to the touch. In a well-ventilated room with a ceiling fan running, upholstery typically dries completely in 4 to 6 hours.
Q: Can I use the Bissell Little Green or Hoover CleanSlate on a mattress? A: Yes! Both machines are excellent for deep-cleaning mattresses to remove sweat stains, spills, and allergens. Just be careful not to over-saturate the mattress with water. Use quick, light sprays and spend extra time suctioning the moisture out so the foam layers dry quickly.
