Stain-Removing and Deep-Cleaning Attachments

Bissell SpotClean Professional (3624)
You have your choice of two cleaning attachments to use with the Bissell SpotClean Professional. The 3-inch-wide attachment has three rows of bristles affixed to it, making it ideal for getting rid of stains. The 6-inch tool is simply a more robust version of the stain-removal attachment, and it’s designed for use on stairs and upholstery.

When pressed, a thumb trigger releases a strong spray of water on the carpet or fabric. As you pull the tools across the area you’re cleaning, the SpotClean Professional suctions water and lifts dirt. Both tools are equipped with a transparent cover, so you can instantly see the stain disappear.

Bissell SpotClean ProHeat (2694)
With the Bissell SpotClean ProHeat, you get two tools. The three-inch-wide brush features three rows of grouped bristles that scrub away spots and stains. The larger brush is not only lined with bristles that deep clean carpeting but also furnished with one row of rubber solution injectors.

Each attachment has a clear nozzle, allowing you to monitor your progress as you clean. To prevent oversaturation, the SpotClean ProHeat generates suction that sucks up the water released by the thumb trigger. As a bonus, you get a HydroRinse tool makes it a breeze to keep the hose free of dirt and odors.

Conclusion: Although Bissell supplies the SpotClean Professional and ProHeat with a see-through stain-removal tool, the ProHeat’s deep-cleaning attachment is more effective thanks to its solution injectors. Plus, the SpotClean ProHeat comes with a tool that rinses the hose in under a minute.

Flexible Hose and Compactly Sized

To help you reach tight, awkward spots, Bissell includes a 5-foot-long flexible hose together with the 3624 model. When not in use, you can store the hose on the side reel. The power cord measures 22 feet in length, which is long enough to stretch from end to end of most staircases. A turn hook allows for quick cord unwinding.

At a weight of 13.2 pounds, the SpotClean Professional is manageable enough for most people to carry by its top-situated tote handle. Its length and width of 10 inches mean the carpet cleaner is small enough to rest on a stair tread and store one tool on board.

Bissell SpotClean ProHeat (2694)
On the SpotClean ProHeat, there is a 4.5-foot hose that flexes to extend the carpet cleaner’s reach and 15-foot quick-release power cord. While the cord winds around two hooks on the back of the cleaner, the hose wraps around the bottom of the ProHeat, securing to a clip.

The 9-pound portable carpet cleaner is incredibly lightweight, and its thick looped handle provides a firm grip during transport up the stairs or to the car. Bissell gives you places on the cleaner to keep both brushes, and its compact size of 6.5 by 12 inches means the ProHeat takes up minimal storage space.

Conclusion: In terms of reach, the SpotClean Professional offers 7.5 more inches. However, the SpotClean ProHeat’s cord is easier to unwrap, and the ProHeat itself is smaller and weighs less than the Professional. The ProHeat also provides two tool storage spots as opposed to the Professional’s one.

Motor Amperage and Separated Tanks

Bissell SpotClean Professional (3624)
For a small, portable carpet cleaner, the SpotClean Professional’s motor is strong and has 5.7 amps of electrical current flowing through it. Although the SpotClean lacks a water-heating mechanism, it’s safe to add hot water at a maximum temperature of 140 degrees Fahrenheit.

The SpotClean Professional’s clean and dirty-water tanks boast a large capacity of 96 ounces. Thanks to the clean tank’s flat bottom, adding water and cleaning solution is a headache-free process, and the collection tank has a wide outlet for easy emptying. Additionally, both tanks have a hinged handle to help you carry them to and from the sink.

Bissell SpotClean ProHeat (2694)
Rated at 2.3 amps, the motor falls on the lower end of the portable carpet cleaner motor-power scale. However, Bissell’s Heatwave Technology more than makes up for it by maintaining the temperature of the hot water you add to the reservoir. A thermal protector stops the motor from blowing in the event that the Heatwave mechanism overheats.

Both the reservoir and collection tank hold 37 ounces’ worth of water and have a recessed grip on their housing. A rubber stopper on the collection tank keeps dirty water from leaking while the reservoir has marked lines to denote the fill level for cleaning solution as well as water.

Conclusion: When it comes to the motor, the SpotClean Professional’s is more powerful than the ProHeat’s. The Professional also has larger tanks that are easier to handle. Regardless, the SpotClean ProHeat is the only one equipped with Bissell’s Heatwave Technology, which means the clean water won’t cool down before you’re finished cleaning.

Convenient for Carpet Touch-Ups

Both Bissell carpet cleaners performs well at removing dirt and stains; however, each one shines in different ways. The SpotClean Professional has a longer hose and power cord. Its motor is more powerful, and it has bigger tanks. The Professional’s tanks are also easier to deal with due to their handle and flat bottom.

With the Bissell 2694 SpotClean ProHeat, you get a portable carpet cleaner that takes up less storage space yet has enough room for all the brush attachments. Hose access is simplified, and the deep-cleaning tool’s solution injectors make it more efficient than the Bissell 3624 Professional‘s stair tool. The ProHeat also comes with Heatwave Technology and a HydroRinse cleaning tool.
