Main differences

In the beginning, we would like to address, that both products are a decent choice, especially in this price range. What’s more, most of the consumers should be satisfied with either one of them. However, there are some things which you should keep in mind before you make the final decision.

The first major difference are the included attachments. Many people don’t pay attention to this aspect, which is a mistake in our opinion. The tools, that come included can often completely change the efficiency of the whole process, so it’s definitely something to keep an eye on.

The Steamfast 275 comes with 15 attachments, whereas the Steamfast 370 has 17 tools included. Additional tools in the 370 model, can make the cleaning process a little more versatile, although the 275 version should satisfy most of the users.

Another important dissimilarity is the power cord length. Although we don’t usually think about this aspect too much, there is a quite significant difference. The Steamfast 275 has a 12 ft. power cord, while the Steamfast 370 has a 15 ft. power cord.

It’s not something, that you should be bothered about unless you don’t have too many outlets and you are not planning on using an extension cord. Although, to be fair, for most of the users the 12 ft. option also should be a satisfactory choice.

The last crucial difference is portability. Using a steam cleaner for whole-house cleaning is, unfortunately, often connected to dragging the unit up or down the stairs. Therefore, portability is something to keep in mind when choosing a new cleaning device.

The Steamfast 275 has a total weight of 10.06 lb., while the Steamfast 370 has a total weight of 8.42 lb. The second one is noticeably lighter and can be a much more comfortable option if you have many stairs in your household.

Those are pretty much all the important dissimilarities, that you should keep in mind. Based on those factors, you can already decide which steam cleaner is a more appealing option for your household. However, if you would like to learn more, we strongly suggest to continue reading the article.

Both Steamfast 275 (Click here to see the price!) and Steamfast 370 (Click here to see the price!) can be found on the Amazon.

Cleaning efficiency

The cleaning efficiency is one of the most, if not the most important factor when it comes to choosing a new steam cleaner. By this, we mean how well a particular unit does, compared to other products from a similar price range.

We honestly have to say, that both Steamfast 275 and Steamfast 370 are decent options, especially in this price range. They are great for cleaning various surfaces, including ceramic tile, grout, granite, sealed wood flooring, laminate, appliances, grills, autos, and more.

Both units can also be used to simply disinfect those surfaces, or clean furniture and different appliances.

As you can see, there are many ways to utilize one steam cleaner, which is one of the reasons those tools got so popular. Both products operate using a similar motor and, therefore, are capable of producing a similar steam rating.

The approximate temperature gets to around 200 degrees Fahrenheit, which should be enough for all the possible utilizations.

One of the aspects, that can alter the overall cleaning efficiency is the hose length. In both units it’s actually the same size, measuring around 6.5 ft. This length allows for removing dirt from those hard-to-reach spots, as well as works for everyday cleaning.

Another factor, that has a major influence on the overall cleaning efficiency are the included attachments. We won’t be getting into details, however, we will touch on those aspects more in the latter part of the article. Nonetheless, it’s worth saying, that the Steamfast 370 comes with 2 more attachments.

To start cleaning, you need to fill the 48 oz. tank, and wait for the water to heat up. In both units, this takes around 8 minutes depending on the temperature of the water. Then, you just need to press a special steam control button to create steam. The button can be also locked in place for continuous steam production.

This process is very similar in every steam cleaner, so you should quickly get a hang of it. There is also a special light indicator, which tells you when the steam is ready. When the light turns off, it’s the sight, that you can start cleaning.

Those are pretty much all the aspects, that you should keep in mind when it comes to cleaning efficiency. Of course, there are also other aspects, which can indirectly influence this aspect (such as the cleaning time), and we will touch on those later.

Tank capacity

The tank capacity is another crucial aspect when comparing different cleaning devices. This will be the main limiting factor when it comes to the maximum cleaning time. It is because opposed to portable cleaners, the manufacturers aren’t limited by the weight of the device.

Both units boast a 48 oz. water tank, which is a pretty regular size for a steam cleaner. This will easily be enough for everyday cleaning, as well as getting rid of a little more stubborn dirt. Especially, taking into account the ease of refilling the tanks. This size of tanks provides approximately 50 minutes of continuous steam production.

Of course, you can get more time, if you are going to use it more sparingly. Nonetheless, this should be enough for most people.


The design is another important aspect since every good cleaning device has to be maneuverable. Additionally, we highly value ergonomic construction, which will ensure you are comfortable, even after long periods of cleaning.

Fortunately, both products in this comparison provide ergonomic construction with great maneuverability. Going around or under furniture won’t be a problem with either one of them. The manufacturer also implemented a number of convenient features, which improve the overall cleaning experience.

One of those features can be a steam indicator light. It tells you whether the steam is ready to use – You just have to wait for the light to turn off, to start the cleaning process. In both units, you can also find a steam control switch, a special button that produces the steam when pressed.

You can also lock the mentioned button, in order to have the steam produced continuously. It’s a great way to rest your hand when you are doing a longer cleaning session.

If you would like to see some more technical information, the Steamfast 275 has the dimensions of 17.32 x 13 x 11.1 in. and weighs around 10.06 lb. The Steamfast 370 on the other hand, measures 15.4 x 9.5 x 12 in. and weighs 8.42 lb.

Those are pretty much all the necessary information, in terms of the design. It’s hard to pick a winner in terms of this aspect, however, the reduced weight in the Steamfast 370 is unarguably a big advantage.

Cord length

The cord length is an aspect, that we don’t pay too much attention to. However, since the difference here is noticeable, we decided to mention it. Although, to be honest, most people won’t be bothered about the short cord length.

That being said, if you don’t have too many outlets around, in your house, and you don’t want to use any extension cords, the Steamfast sf370 will be a better option. It boasts a 15 ft. power cord, which is noticeable longer, than the 12 ft. power cord in the Steamfast sf370.


The price is usually the first thing you research when comparing different steam cleaners. However, since there are so many markets and the price often fluctuates, it may be hard to get up-to-date information.

Both steam cleaners can be found in a similar price range, however, there is a small price difference. The Steamfast 275 is listed on Amazon for the price of $159.99 (Click here to see the price!), while the Steamfast 370 can be found on Amazon for the price of $119.99 (Click here to see the price!).

To decide on a better option, you need to consider whether the additional benefits of the Steamfast 275 are worth the price difference.

Package content

The package content, as we earlier said, is an aspect often skipped by many customers. In our opinion, it’s a mistake since the attachments included, can really change the way you are thinking about everyday cleaning.

The Steamfast 275 comes with a number of tools included, and those are:

  • 2-Extension Wands
  • Mop Head
  • Scrub Tool
  • Sponge Pad For Corner Tool
  • Scrub Pad For Corner Tool
  • Brass Utility Brush
  • 2-Nylon Utility Brushes
  • Corner Tool
  • Measuring Cup
  • Squeegee
  • Jet Nozzle
  • 2-Microfiber Pads
  • Steam Cleaner

The Steamfast 370 also comes with an impressive number of extras, and those are:

  • Jet Nozzle
  • 2 Nylon Utility Brushes and Brass Utility Brush
  • Squeegee
  • Scrub Tool and Corner Tool
  • Scrub Pad and Sponge Pad for Corner Tool
  • 2 Extension Wands
  • Mop Head and 2 Microfiber Pads
  • Measuring Cup

Those are pretty much all the extras, that can be found in the package. In our opinion, in both cases that should be enough, even for an everyday user. That being said, the Steamfast 275 has more attachments included which can be an advantage to some people.

Necessary maintenance & warranty

The necessary maintenance and warranty are another two aspects, which are often missed by people who compare particular products. Maintenance is a crucial activity if you want to keep your new steam cleaner operating at the desired level and prevent any permanent damage.

When it comes to the warranty, both products have included the 2 years limited warranty.

We won’t be getting into details when it comes to the necessary maintenance, as it would make the article simply too long. We will, however, give you a few quick tips, that can be very useful when it comes to this aspect. Those steps should apply to most steam cleaners.

In order to keep your new device working at the desired level, you need to:

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

To learn all the crucial maintenance steps, we highly recommend reading the user guide. You will learn everything you need to know from there.


In conclusion, both steam cleaners are a decent choice, especially in this price range. What’s more, most people should be satisfied with either one of them. That being said, there are some things to keep in mind before making the final choice.

To some of the most important differences, we can include the attachments (Steamfast 275 has 17 accessories while the Steamfast 370 has 15 accessories), power cord length (Steamfast sf370 has 15 ft. long power cord when the 275 version has only 12 ft.), and portability (Steamfast 370 is lighter).

Based on those factors, you should easily decide which steam cleaner is a better option for your household. In our opinion, the Steamfast 275 is a winner of this comparison, due to more attachments and a longer power cord. Although, it’s safe to say, that the Steamfast 370 will do comparably well most of the time.

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