It also automatically dries the carpet with heated air every time you pull the machine backwards.

2. Bissell ProHeat 2X Carpet Cleaner
If we’re going to be writing a review of the top performing carpet shampooers, the Bissell name is bound to come up. In this case, we’re talking about the Bissell ProHeat Revolution Pet carpet cleaner.
Not only is this an ideal machine for pet lovers, but Bissell also has the best cleaning products for homes with pets. When using this carpet cleaner together with the Bissell Professional Pet Urine Eliminator + Oxy formula and the Antibacterial formula that goes with it, you’ll get the best results when cleaning up after your pets. Bissel claims that the Pet Urine Eliminator carpet shampoo is able to remove even skunk odor. So if you own a skunk (like so many people do), there can be no better carpet cleaner.
Regardless of what carpet shampoo you choose to use, the Bissell ProHeat Revolution has what it takes to deep clean any carpet – removing even the toughest stains. The DirtLifter Power brushes use what they call heatwave technology, though I’m not exactly sure what this means. Whatever it does, these brushes are excellent at working the detergent into the carpet and lifting away seriously ingrained grime which is then sucked into the dirt collection tank. It has a CleanShot pre-cleaner that sprays heated cleaning formula directly onto stubborn stains when needed. This is really effective at removing stains that many competing models aren’t able to do.
If you want your carpets to dry quickly, you can forgo the deep cleaning mode and opt for the express clean mode that will leave your carpets dry after about an hour. This would depend on weather conditions though, on a cold rainy day it’s obviously going to take longer for the carpets to dry. It also comes with a 2-in-1 wet/dry pet upholstery tool. This can be used as a dry vacuum to remove pet hair from your furniture and can also clean your upholstery when using the wet mode.
The Bissell ProHeat Revolution carpet cleaner isn’t all that bulky, the extra pipes and 2-in-1 upholstery cleaner come in a separate bag, reducing the size of the machine. It has a reasonable weight for a powerful carpet cleaner at 20-pounds. What may well be the most outstanding feature of this Bissell model is in that it’s so easy to clean. The brush cover can be removed with a quick unclipping action. This means that you have easy access when you need to clean and maintain the carpet cleaner. It’s clear that the Bissell ProHeat 2X Revolution Pet Pro 1986 is an excellent choice for homes with pets. For that matter, it’s one of the best even if you don’t have pets and it comes with an outstanding 5-year limited warranty.

The Antimicrobial Pet Tool is small enough to get in anywhere, so you clean areas where many other carpet cleaners cannot.
The Hoover Power Scrub Elite can easily be the best when it comes to convenience. It weighs only 18.5-pounds and has four really convenient carrying handles. The clean water and dirty water tanks a bigger than most, each holding 1.25-gallons and the detergent is mixed automatically. The water tanks are removable, as are the brushes.

5. Hoover Power Scrub Carpet Cleaner
Staying with the Hoover brand, we’re stepping things up here in the form of the Hoover Power Scrub Carpet Washer (FH50150). This incredible carpet cleaner shares all the same great features of the SteamVac with some additional ones. Making this one of the best Hoover carpet shampooers. The Hoover Power Scrub has the same SpinScrub roller brush as the other Hoover model.

This means no measuring and mixing, the Hoover will ensure that you always have the correct ratio of clean water to the cleaning formula.

6. Rug Doctor Deep Cleaner Carpet Cleaner
As one would expect from Rug Doctor, this is a professional grade carpet cleaner. The industrial strength and power of this machine have earned it a Gold rating from the Carpet and Rug Institute (CRI). Out of the top-end upright carpet cleaners tested, the Rug Doctor proved to be 75% more powerful than any of the others.
Of course, having a commercial grade carpet cleaner does mean that you have to deal with a larger, heavier machine. The Rug Doctor Carpet Cleaner weighs 25-pounds – quite a bit more than the other carpet cleaners in this review. The engineers have done a lot to make this carpet cleaner more manageable, considering its size and weight.
It has a large grip at the top of the handle, making it easy to use with both hands. The large rubber-clad wheels aid its maneuverability and won’t harm your floor surfaces. When it comes to storage, the Rug Doctor may even be better than the smaller machines. The handle folds down to make it more compact when storing.
With its professional-grade dual action cross brushes, consisting of 14 rows and the improved suction, the Rug Doctor easily has the best cleaning power of any home carpet cleaner. The high suction of this carpet cleaning machine removes more water from the carpet than most others. This means a shortened drying time of 4-hours. This doesn’t look too impressive when compared to the carpet cleaners with heat-assisted drying, but for a heavy-duty commercial grade machine, this is one of the best. You can boost your cleaning for heavy traffic areas and serious stains, by easily applying extra cleaning solution with a control at your fingertips.
The separate clean and dirty water tanks are really large, each holding 1.1-gallons. This is fantastic for large homes with a lot of carpeted flooring. These tanks have over-sized openings for easy filling. It has a 12-inch cleaning path and an upholstery cleaner that uses a 7.7-foot hose. Another advantage when cleaning large areas is the extra-long 28-foot power cord. All the cleaning attachments and the hose fit into a neat caddy that attaches to the machine. This is a convenient storage system that gives you quick access to the tools at any time.
For those of you who want a carpet cleaner that matches the cleaning capabilities of a commercial grade machine, the Rug Doctor is bound to impress you. Naturally, a carpet cleaner of this caliber is going to cost more than most, but it can easily be considered as the best in its class. The 2-year limited warranty for domestic use has basically no real limitations – you really have to abuse the carpet cleaner to nullify the warranty. It also has a 1-year commercial warranty, proving that this machine is up to the task of heavy-duty commercial carpet cleaning work.

There are quite a few reasons why many might see the Bissell Deep Clean Premier as being the best for pet owners.

10. Bissell 1887 Proheat Carpet Cleaner
As you can see, Bissell models dominate the list. This is due, in part, to their popularity in being high-quality machines and their extensive range of products in all price categories. The Bissell 1887 Proheat Essential carpet cleaner is on the lower end of the price scale. The lower price, when compared to other high-end carpet cleaners, is not so much because this is an inferior model but rather that it’s smaller. The Bissell Proheat Essential is, therefore, is a good choice for smaller homes or less carpet areas to clean.
One of the cool factors in having a smaller carpet cleaner is that this model is more compact and lighter than most other Bissell models. The Bissell Proheat Essential weighs only 19.8-pounds. This does mean that it’s not going to clean a large area as quickly as the others, but it still has the superior cleaning abilities of all the others.

Important Features of an Effective Carpet Cleaner
What are the most important features in an effective carpet cleaner? What features are over-hyped or counterproductive when it comes to these machines?
An effective carpet cleaner needs strong suction to pull as much shampoo out of the carpet as possible. Carpet cleaners with powerful water jets and heavy duty brushes but weak suction will leave carpets clean but damp, at best taking hours before you can walk across them and at worst taking days to dry while nurturing mold growth.
Carpet cleaners don’t actually use steam, though some generate so much water vapor they seem to use steam. However, some units not only use hot water but heat up the water. The ideal carpet cleaners can heat up lukewarm water, but good ones can keep the hot water you add warm. This keeps the cleaning solution warm and effective as you continue to work. But if you are looking to sanitize your carpet without the use of the chemical cleaners, then you need a carpet steam cleaner. Steam cleaners use hot steam that regular carpet cleaners are unable to.
Thorough Scrub Brushes
An often overlooked but critical feature of carpet shampooers is the quality of their scrub brushes. Will they remove dried juice stains, that mess the puppy made or where the cat threw up out of the carpet? And will they remove not only the goo on the surface but what seeped into the carpet itself? Another factor to consider is how hard the brushes are on the carpet. If you put the carpet cleaner on a spot to scrub out a deep stain and it rips up the carpet in the process, it isn’t a fair trade-off.
Carpet cleaning machines tend to be heavier, bulkier and harder to move around than vacuum cleaners. Even spot cleaners are harder to use compared to handheld vacuum cleaners.
Ease of Emptying the Dirty Water Tank
The ease of emptying the dirty water tank is more important than the ability to put clean water in the unit because spilling used water creates a new, nasty mess while spilling clean water is solved by drying the area with fans. Too many units, too, use dirty water tanks that are nested inside of the clean water tank so that you have to manipulate both in order to empty the waste water. The ideal machines have separate dirty water tanks that are easy to remove without touching the clean water tank.
Another aspect of this is how easy it is to get all of the dirt and debris out of the used water tank. If the dirty water tank has nooks and crannies that trap debris or gunk in it so you can’t get it all out, the machine will start to stink over time.
Separate Dirty and Clean Water Tanks
This feature is too often overlooked, but it is an essential feature if you want truly clean floors when doing more than spot cleaning. If you have a single water tank for clean water and waste water, the dirt that you just pulled up gets pumped into the tank that gets progressively dirtier. The end result is that the last areas you clean may end up dirtier than they were before.
Less Important Features of Carpet Cleaners
1. The set-up of the clean water tanks in the carpet cleaners matter but not as much as the features above. If the machine meets the criteria above, one of the next features to look for are separate clean water and soap reservoirs. You want soap and clean water reservoirs separate so that you only have to add as much soap as required.
2. Spin scrub hand tools that let you scrub a particular area. These tools tend to be weaker than the full unit, but it is the only way to thoroughly spot clean upholstery. Crevice tools are rarely useful, since it is hard to get these nooks and crannies in furniture dry after you’ve shampooed them. Tools like hard floor attachments rarely do as good a job as an old-fashioned mop, and they become outright dangerous if someone takes the machine onto a hardwood floor.
3. Trigger spray dispensers on carpet shampooers are a nice to have. They are considered essential since you have the options of spraying the solution via a spray bottle on your own or making multiple passes with the shampooer. And these trigger spray dispensers separate from the standard shampoo jets and are prone to clogging, which is a reason you may not want them at all.
4. The ability to have a separate rinse of clean water is another luxury that is not needed as often as others claim. You may need to make more than one pass to lift up the stain or give it a pass with a standard vacuum cleaner to lift up all the moisture. If the shampooer model has a tendency to spray too much shampoo and sells its water sprayer as the solution, it is better for you to use a model that doesn’t waste that much soap and risk leaving floors too sticky from soap residue.
5. One reason why many carpet cleaning machines have a single large water tank where the debris builds up over time is because of the size and bulk of the tanks. Yet you need a large clean water tank if you don’t want to have to make multiple trips to refill it. Conversely, you want a large waste water tank so you don’t have to make five trips to the sink to empty it. The challenge is balancing the capacity of the clean and dirty water tanks with the ease of emptying them. Overall, we consider the ease with which you can empty the dirty water tanks more important than the need to take two or three trips to the sink to empty them.
