Main differences

At the beginning, we would like to address, that both products provide a very satisfying cleaning experience. Removing most of the stains and dirt shouldn’t be a problem for either carpet cleaner, however, there are some crucial differences, that you need to know about.

The first and main difference is the cleaning efficiency. The brush tool used in the Bissell Little Green 1400m is more efficient than the one in the Bissell Little Green 1400b. This is due to the brush running at a much faster pace. This allows for better dirt removal and, in the end, better cleaning efficiency.

The second crucial difference is the weight and overall design. The Bissell Little Green 1400m comes in darker green and is heavier, compared to the 1400b version. Although, the difference is rather small, as it’s only 0.2 lb. The dimensions of both products are also different – The Bissell Little Green 1400m measures 19 x 14.5 x 10 in., while the 1400b version is 8.25 x 17.25 x 12.5 in.

Those are pretty much all the important dissimilarities. In order to make the final decision, you need to think about what you are after. If you are looking for a slightly more portable solution, you may consider picking the 1400b version, and if you want to maximize the performance, 1400m would be a good choice.

In our opinion, the Bissell Little Green 1400m is a better choice, due to the more efficient brush tool. Even though the difference isn’t big, we highly value good cleaning efficiency. At the same time, the 0.2 lb. difference in the weight, doesn’t feel too important.

Based on those factors, you can easily decide which carpet cleaner is a better choice for your household, although, we highly recommend to continue reading the article. You will learn more details about each of the products, as well as find out some useful maintenance tips.

Cleaning Efficiency

Cleaning Efficiency is probably the most important factor when it comes to picking your new carpet cleaner. By this measure, we mean how effective is a particular product at removing the dirt and deeply embedded stains from your carpet.

As we said, both products do a fairly decent job at removing even the dry stains. Honestly, we think, that each of the cleaners should satisfy most of the users when it comes to day-to-day cleaning.

The cleaning technology implemented by the manufacturer is practically the same.

There is, however, a slight difference in cleaning performance between those two products. The Bissell Little Green 1400m has a little more efficient brush tool, which results in better cleaning performance overall. The brush can run at a faster pace, removing the stains and dirt better.

The tank capacity of both products is the same, which is exactly 48 oz. This much water should be enough for removing all the dirty spots from your carpet. Because as the manufacturer clearly states, those are only spot cleaners.

Since we are talking about the tanks, those are also easy to fill, thanks to the convenient design. You can easily detach each of the tanks to fill or empty them. To prevent from spilling, there’s also a cap. The proper level of water and solution is marked on the tanks, so you won’t overfill them.

Another thing you need to know is the trigger located at the brush tool. During the cleaning process, you will rely on the trigger, that sends a stream of water mixed with solution on the desired spot, and dry sucking. While the first couple of passes may not be enough for dry stains, pouring some more water with solution and running the spot over with the brush should do the job.

This is pretty much all you need to know when it comes to cleaning efficiency. The carpet cleaner, that is slightly better when it comes to this factor is the Bissell Little Green 1400m.


What’s also important for this type of carpet cleaner is the portability. Since those are spot cleaners, they should be easy to carry around in case of any unexpected spills or smudges. Luckily, both products offer a pretty lightweight design, which allows you to freely transport them.

Thanks to the low weight, those spot cleaners are also a common choice for cleaning the car upholstery. We highly recommend using them in your car, even if you think, that it’s relatively clean. You may be surprised to find out how dirty the seats actually are.

The devices also slightly differ when it comes to portability. A better choice here is the Bissell Little Green 1400b, due to the 0.2 lb. lighter design, which is exactly 12 lb. Therefore, the 1400b version weighs 12.2 lb.

The Bissell Little Green 1400m is also a little bigger, measuring exactly 19 x 14.5 x 10 in., while the 1400b version is 17.25 x 12.5 x 8.25 in.

An important aspect when it comes to portability is the power cord. Fortunately, both models have a pretty sufficient length of 15 ft. Considering, once again, that those products are spot cleaners, this should be enough for most of the consumers.

Taking all the aspects into account, the Bissell Little Green 1400b is a better option in case of portability. 

Ease of use & package content

Another factor, that we value in our tests is the ease of use. The more intuitive is a particular cleaning device, the better. Most of the time, you don’t need any special settings or customizability, in order to effectively clean your carpets, so we decided to take it into account.

When either of the products finally arrives, in the box you can find a cleaner, hose, brush tool, two holders (which you need to pop into the main unit), a power cord, and cleaning formula.

The whole unit is almost ready to use, all you have to do is pop two parts into the main unit. This assembly is effortless and you can start using either one of the products, right after you finish.

The cleaning process also isn’t too demanding – It all relies on spraying the dry stains with water and solution mix (using the trigger on the brush tool) and dry vacuuming with the brush tool. Since the first few passes may not be enough, you just need to focus on more demanding spots.

There are no significant differences when it comes to the ease of use, therefore you need to base your opinion on other factors.

Necessary maintenance

Maintenance is an important step after buying any cleaning device. Lots of people don’t understand how crucial this process really is. It not only helps you keep the unit running at the desired level but also reduces the chance of any permanent damage.

In order to learn all the necessary steps when it comes to maintenance, you should read the user’s guide of the particular product. However, we will try to give you all the most important steps when it comes to the maintenance of any carpet cleaner.

To keep your unit running at the desired level at all times, you should:

  • Regularly rinse both clean and dirty water tanks
  • Regularly check the brush roll for any stuck dirt and/or debris
  • At least once a week clean the cover of the brush, nozzle, and rinse the tank
  • Replace any used or damaged elements as fast as possible

Once again, we highly recommend reading the user’s guide to learn all the most important maintenance tips for your new cleaning device.


Both spot cleaners are a great choice for removing stubborn stains and deeply embedded dirt. If you often find yourself cleaning the carpets, either one out of those two devices should be a big relief. There are, however, some crucial differences, that you should know about before you make the final decision.

Some of the most important dissimilarities between those two carpet cleaners are the cleaning efficiency (the 1400m version is better at removing stubborn stains), design (different colors), and portability (the 1400b version is 0.2 lb. lighter and little bigger than the 1400m version).

Based on those factors you can freely decide on the best carpet cleaner for your situation. If you would like to know our opinion, the Bissell Little Green 1400m is a winner in this comparison. This carpet cleaner has a slightly better cleaning efficiency, which is the most important aspect for us.

We hope, that after reading this article, you will be satisfied with your final choice.
