Similarities and Differences
At a surface level, the Spectra S1 and Spectra S2 pumps look identical other than the color.
And whilst these two pumps are in fact very similar, there are some key differences that set these two pumps apart.
So, let’s take a closer look with my Spectra S1 vs S2 comparison!

Pump Design
The obvious difference between these two Spectra pumps is that the Spectra S1 is blue in color and the S2 is pink. And no, this doesn’t mean one is for boys and one is for girls.
It is simply an easy way to tell these two pumps apart.
Color aside, these two pumps are the same in design. Both are closed systems, that connect your milk collection unit to the pump motor via tubing.
Both pumps are relatively light weight with the S1 weighing 3lbs which is slightly heavier than the S2 which is only 2.5lbs.
They can be used for single or double pumping.
And both have an awesome built in night light for those late night pumping sessions and a very handy bottle holder!

Flange Design
Both the Spectra S1 and S2 pumps come with the same flange and bottle design. This setup means that you can pump directly into your storage bottle without the need to transfer your breast milk. I think this is very convenient.
The flange/bottle design consists of a few key components:
- The flange comes in various sizes to ensure a proper fit around the nipple, creating a secure seal for effective suction.
- Attached to the flange is a duckbill valve that controls milk flow into the collection bottle.
- The backflow protector, part of Spectra’s closed system design, prevents milk from entering the tubing and pump motor, maintaining hygiene and prolonging the pump’s lifespan.
- Wide neck bottle
- The tubing connects the flange to the pump motor, facilitating the suction needed for milk expression.
One thing to note is that the S1 and S2 breast pumps can also be sold just as the pump motor and without the Spectra bottles and flanges.
I actually like this as it gives you the option to choose your own Spectra compatible bottle.
Or you can simply choose to use the Spectra flange and bottles.

Pumping Modes and Suction Levels
Again, when it comes to the pump modes and suction levels, you’ll find that these pumps are exactly the same.
Both the S1 and S2 Spectra pumps have two modes:
- The massage mode which is fixed at 70 CPM and cannot be adjusted.
- The expression mode which has 5 different cycle levels: 54, 50, 46, 42, and 38.
Both pumps offer a powerful suction strength of up to 270mmHg which can be adjusted by 12 suction levels.
Tips for Effective Use of Spectra Breast Pumps
When it comes to using your Spectra S1 or Spectra S2 breast pump efficiently, there are several strategies you can employ to maximize comfort and milk expression:
- Adjust Vacuum Levels Gradually: Begin pumping with a lower suction setting and incrementally increase it until you find a comfortable and effective level. Balancing comfort with efficiency is crucial for optimizing milk output.
- Select the Right Flange Size: Ensure you are using a flange that fits properly. An ill-fitting flange can reduce the amount of milk expressed and cause discomfort. Manufacturers offer a range of flange sizes, so choose one that provides the best fit.
- Create a Relaxing Environment: Stress can negatively affect milk letdown. To promote relaxation, ensure your pumping area is calm and soothing. You might also make use of features like a massage mode if your pump offers it, as this can help stimulate milk flow and enhance letdown.

Battery Life and Charging
I know you’ve been waiting to find out what the biggest difference is between the Spectra S1 and S2 pumps, and it’s the battery!
The Spectra S1 comes with a rechargeable battery that can last up to 3 hours of operation on a single charge. Recharging your battery will take around 4 hours.
The Spectra S2, however, needs to be always connected to a power source to work. It is not battery operated or portable.
LED Screen
Both pumps have an easy to read LED screen. It displays all your key pumping information including your pumping cycle, timer, and suction level.
A minor difference is the S1 also displays your battery life.

Noise Levels
The Spectra S1 and S2 have a similar noise range at less than 45 dB.
Price And Value For Money
There is isn’t a huge difference in price between these two pumps, but as you might suspect the Spectra S1 is more expensive that the Spectra S2 given the convenience factor of the rechargeable battery.
The Verdict
If you’ve decided you want either a Spectra S1 or Spectra S2 pump, then to decide which is the best Spectra pump for you, ask yourself do I need the portability or not?
If no, then the Spectra S2 is the more affordable option and thus the better choice given these pumps are essentially the same other than the portability option.
If you want the portability, or even if you are not sure, then I’d opt for the Spectra S1. Having the extra option for portability is a big plus in my books.
That said, I know a lot of pumping moms like to use the Spectra as their main pump for home or work given it is such a workhorse, and then purchase a second wearable breast pump like the Momcozy M6 or M5 for the convenience and discretion when on the go. So just another option to consider when making your Spectra pump purchase.
