Bissell, a US company, based in Michigan, is famous for its 2-in-1, vacuum and mop, cleaners. These are versatile, mid-range vacuums that are specifically designed to help pet owners combat pet hair and messes.

Their dry and wet vacuum cleaning modes also make them a perfect choice for removing the dirt that gets tracked deep into the carpets. This dual function means that the vacuum cleaner eliminates the need for purchasing two separate cleaning tools. It also saves you money that you’d otherwise use you for professional carpet cleaning.


The 15651 comes from one of Bissell’s product lines, dubbed Proheat 2X Lift-Off Pet. This line gets its name from the fact that it uses a dual cleaning brush system and Bissell’s Proheat technology that we’ve explained in detail in the next sections of this review.


This carpet cleaner will come halfway assembled for secure shipping. Luckily, all that you’ll need to assemble it fully is a screwdriver. The only assembling process involved is sliding the handle into the main component and tightening it using four screws that are attached on the handle itself.

Construction Design

Before getting deeper into this Bissell Pro Heat 2x Lift Off 15651 review, let’s brush over its construction design.

As a 2-in-1 unit, you can use this cleaner as an upright vacuum when dealing with the carpets in general, and as a canister when cleaning the stairs. The ability to clean the stairs without struggling to lift the entire upright vacuum cleaner is among the most significant benefits that this particular vacuum cleaner offers compared to vacuums from other Bissell lines, including Crosswave.

Size and Weight

When fully assembled, this vacuum cleaner has a height of 44 inches from the brush roll to the top of the handle, a width of 13 inches, and a depth of 19 inches. This is pretty much the size of most upright vacuum cleaners.

However, at 24.03 pounds, this model is a few pounds heavier than most typical upright vacuum cleaners that we’ve reviewed so far. This slight increment in weight is understandable, though, considering that the Bissell 15651 packs 2 separate vacuum cleaner designs. Again, a good amount of its weight comes from its dual brushroll configuration and twin water tanks.

Amazingly, there were no complaints regarding weight from the reviews that this vacuum cleaner had garnered when compiling this article. Actually, several buyers, including this one, reported that this machine is lightweight enough to make weekly or biweekly carpet cleaning an easy task.

Cleaning Reach

This vacuum cleaner’s incredible amount of reach is another of its key highlights. The power cord itself offers you a range of 22 feet while the hose has a length of 6 feet. So, roughly, this pet hair carpet cleaner affords you at least 26 feet of reach. This is more or less enough to clean most rooms from a single wall socket.

This reach is then complemented by the 12-inch cleaning path that the brushes offer. The swiveling head also goes a long way in letting you access hard-to-reach areas, including under furniture.

Bissell Proheat 2x Lift Off Review: Key Features and Strengths

Dual cleaning modes

This vacuum cleaner offers you two choices when you are using it. You can use it as a typical upright vacuum cleaner by pushing it across your carpeted floors and area rugs. When you want to do spot-cleaning, simply lift off the pod that sits snuggly at the front of the base and take it where you need it. This versatility is what makes cleaning the stairs and auto interiors possible.


Dual DirtLifter Power Brush

The Bissell Proheat 2x Lift Off 15651 uses two brushes to offer twice the agitation that you’d experience with typical vacuum cleaners with the lowest price on Amazon. Besides making it an ideal vacuum cleaner for pet hair, the dual brush roll design, coupled with the 6.7A motor, makes the perfect combination for giving your carpets a deep clean whenever there is a need.

Utilizes Proheat technology

When cleaning your carpets using this unit, you can use either warm or cold water. For those instances when you’ll be using warm water, don’t forget to activate the Proheat technology that is built into this vacuum cleaner. Although this technology won’t make the water hotter, it maintains the temperature throughout the cleaning process, thereby making it easy to remove stains and odors.


What accessories are included with the Bissell Proheat 2x Liftoff?

Besides the dual Dirtlifter Power Brush set, the Bissell Proheat 2x Lift Off Pet Carpet Washer, and Shampooer also comes with;

  • Tough stain tool– this 3-inch tool is ideal for cleaning furniture, stairs, and hard-to-reach areas.
  • Spraying crevice tool– great for spot cleaning and pulling dirt sitting in narrow spaces and crevices.  
  • 6ft hose– for added reach.
  • 2 Bissell Carpet Cleaning shampoos.

Bissell Proheat 2x Revolution vs Lift Off

The Liftoff and Revolution come from Bissell’s Proheat line. Both of them feature dual cleaning brushes, a twin water tank configuration, and Proheat water heating technologies.

The major difference between them is the 2-in-1 design of the Lift Off that allows you to lift off the pod. This design is handy for maneuverability and spot cleaning. It also makes it a breeze to clean hard-to-reach areas, including stairs and inside your vehicle.

On the other hand, the Revolution has a couple of functions that leave the Lift Off jealous, including two carpet-cleaning modes, and Clean Shot pre-treater. In addition, this vacuum cleaner has a longer hose, and it also includes lots of accessories that you’d otherwise have to purchase separately with the Proheat 2x Liftoff.

Frequently Asked Questions

How do you replace Bissell Proheat 2x Lift Off belt and brush rolls?

  • To replace either of these, all you’ll need is a screwdriver. Here is how to go about it; 
  • Start by removing the canister by lifting it off. 
  • Remove the three screws that are used to tighten the four nozzles and pull the nozzles out. 
  • Locate the side where the pad release pedal is located. Next, lie the vacuum cleaner with the pedal on the bottom. 
  • Use the screwdriver to remove the end cap by removing the screws. 
  • Remove the single screw that holds the pivot arm and gently pull the arm off. 
  • At this point, it should be easy to inspect the condition of the belts and the brush rolls and remove them too. Importantly, when removing the brushes, make sure not to lose two caps located at the end. 

How do I fix Bissell Pro Heat 2x Lift Off loss of suction?

There are two leading causes of loss of suction with the Lift Off. First, the dirty water tank may be full and, therefore, won’t take any more water. The solution here is to empty it. Secondly, one or both of the water tanks may not be sitting correctly on the canister. Lift each of them off and replace them, ensuring that they fit snugly. 

Why is my Bissell Pro Heat 2x Lift Off not spraying?

If your Lift-Off is not spraying the solution, the problem may be caused by an empty water tank. So, check it first and refill if necessary. If that’s not the problem, another issue could be that the removable canister is not sitting well on the base. Lift it and replace it, ensuring that it is not slanted.
