Bissell Little Green vs ProHeat (2022): Which Carpet Cleaner Should You Buy?

While vacuums are a staple in every home, they’re not exactly an all-in-one machine. For tougher surfaces like carpets and rugs, a carpet cleaner is better. In this category, Bissell is one of the most reliable brands. The Little Green and ProHeat are two of its most popular cleaners, but they couldn’t be more different. Bissell’s Little Green machine thrives on being a portable appliance. On the other hand, the ProHeat is more of your high-capacity upright model. Given these differences, when do you choose one over the other?

Bissell’s Little Green has a unique, highly portable design, while the ProHeat comes with a larger body that resembles traditional vacuums.

When it comes to design, the Bissell Little Green and Bissell ProHeat Essential couldn’t be more different. The Little Green is a compact appliance with an unusual, dome-like form. Its body is sandwiched between two tanks β€” one for the cleaning solution and another for collecting dirt.

On the Little Green’s top, you’ll find a handle that allows you to carry it around. Meanwhile, a flexible hose wraps around the base of the machine. As its name suggests, the Little Green comes in an avocado-green color finish.

In contrast, the upright Bissell ProHeat more closely resembles traditional vacuums. However, compared to vacuums, the ProHeat has a larger base to house its water tank and cleaning components. As it moves up, the body narrows to a height of 3.5 feet.

Like the Little Green, the ProHeat’s upper handle comes with a hook that serves as a cord wrap. There’s also an ergonomically designed spray trigger on its handgrip. Bissell’s ProHeat comes in a sleek black finish with red accents on the body and on its lifting brush.

Cleaning Power

The Bissell ProHeat is more powerful than the Little Green Machine.

Bissell’s Little Green is portable enough to use for car interiors (left), while the ProHeat is limited to the house (right).

The Bissell Little Green is equipped with a 3-amp motor for strong suction. It’s not as powerful as a vacuum cleaner like the Dyson Cyclone V10, but it gets the job done. Based on user reviews, the Little Green is suitable for tackling spot stains and daily messes. However, it’s not perfect, and some stubborn stains aren’t as easy to remove using the cleaner.

On the other hand, the Bissell ProHeat Essential boasts a more powerful 6-amp motor. Aside from its suction power, the ProHeat can also lift more debris thanks to its PowerBrush technology (more on this inΒ Features and Accessories). These two features on the ProHeat β€” suction and cleaning bristles β€” work together to remove not only dirt but also allergens and odor.Β 

Bissell’s Little Green has a tank capacity of 48 oz, while the ProHeat has a tank capacity of one gallon. Both machines are suitable for stairs, carpets, and rugs but the Little Green’s design makes it useful for upholstery and auto-interiors, too.

Features and Accessories

The Bissell Little Green attachments are fewer than the ProHeat’s.

Bissell Little Green vs ProHeat Features and Attachments
Here’s a look at the Bissell carpet cleaners and their default cleaning attachments.

The Bissell Little Green and ProHeat are both packed with features. The Little Green, for instance, comes with a flexible hose that’s easy to maneuver. Cleaning it is easy, too, thanks to a HydroRinse Self-Cleaning Hose Tool. On the other hand, the Bissell ProHeat’s biggest draw is a HeatWave Technology that maintains water temperature during the deep cleaning process.

Now, the Little Green’s hose is capped by a 3-inch Tough Stain Tool attachment. It’s basically a brush with 15 sets of packed bristles that help loosen tough stains on any surface. With its scrubbing mechanism, the Tough Stain Tool is ideal for cleaning auto interiors. And because it’s smaller, you can target spots and clean upholstery without heavy lifting.

However, if you want to clean faster, the Bissell ProHeat is a better option. The ProHeat’s base can cover more swaths of floor area, including along baseboards. Its default cleaning tool is theΒ DirtLifter Power BrushΒ which comes with six rows of rotating cleaning bristles. You can also attach other cleaning tools to a dedicated knob near the machine’s base.

Bissell shares the ProHeat is compatible with two attachments β€” a standard hose that comes with a Tough Stain Tool and a Spraying Crevice Tool. The latter is suitable for targeting corners, edges, or hard-to-reach areas in your home.

Cleaning Solutions

The Bissell Little Green and ProHeat come with their respective cleaning solutions.

Bissell’s cleaning solutions and tools work together to remove dirt, stains, and allergens in your home.

Bissell’s carpet cleaners work best with their proprietary formulas. For instance, the default Bissell Little Green cleaning solution is the Spot & Stain with Febreze Freshness mixture. Designed for portable carpet cleaners, the Spot & Stain can tackle stubborn messes, including coffee, grease, and wine. According to Bissell, the formula is pet and family safe, too.

The Bissell ProHeat, on the other hand, comes with the PRO MAX Clean + Protect Formula. Unlike Spot & Stain, the PRO MAX solution works on ground-in dirt and stains. It’s suitable for soft surfaces like carpets and rugs but is also effective in tackling soiled areas around the home. Like most of Bissell’s cleaning products, the PRO MAX follows an earth-friendly formula.

Bissell offers several other cleaning solutions aside from these default options. They typically come in 48 oz and 60 oz sizes and are available in bundles and kits as well.


If you’re on a budget, the Bissell Little Green is a solid purchase. However, if you have money to spare, the Bissell ProHeat will deliver a better clean.

It’s also a lightweight appliance that you can carry around anywhere in your home β€” and even outside to clean your car’s interior.

Now, if you want a deeper clean, opt for the Bissell ProHeat Essential instead. This vacuum-like machine uses heat technology for a more consistent clean. Its larger base and extra cleaning tools mean you can clean more while still targeting specific areas in your home.
