Spectra S1 and S2 similarities

There are a few key differences between the Spectra S1 and Spectra S2. But, naturally, they also have a few key similarities. Let’s get the similarities out of the way so that we can focus on the key differences between the two models.

Both include a timer function which lets you know when to stop pumping
Both have a cycle speed control
Both offer single and double-pumping options
Both weigh 3lbs (1.36kg)
Both have a night light function for late-night pumping
Both use an LCD screen for you to cycle through options and settings
Both come with a standard two-year warranty from the date of purchase

Spectra S1 and S2 differences

Despite having many similarities, when comparing the Spectra breast pump s1 vs s2, there are a few key differences that will be the deciding factors for any mom trying to decide between the two breast pump models.

The Spectra s1 is blue, while the Spectra s2 is pink
Despite being the same weight, the s2 is slightly smaller in size
The s1 has a built-in battery which lasts for 3 hours
The s1 is generally around $15/£10 more expensive

The big deciding factor, especially when looking at Spectra breast pump reviews s1 vs s2, is the s1’s built-in battery. This can be charged at the wall, then allows for three hours of independent, mobile pumping. There’s no Spectra s2 rechargeable battery, which puts the s1 ahead, in my opinion.

When you look at Spectra s2 breast pump reviews, this omission of a built-in battery is usually the deciding factor for moms who choose to pick up the Spectra s1 instead. This extra mobility is so important and adds a lot of quality-of-life improvements.

For an extra $15/£10, you’re getting a built-in battery that helps so much with the freedom to pump when and where you need to. This freedom is very much worth that extra bit of money.

So, which is better?

It’s a close call, but if I have to choose one, I’d take the s1.

They’re so alike that it comes down to two things for me: the color and the battery.

Now, I understand that you might want a color that matches the sex of your little one. I have two boys so baby blue comes naturally to me. However, the built-in battery just makes the S1 slightly better. If you’re out a lot; visiting family or friends, in the car, or traveling, you’d want a breast pump that’s mobile and easy to bring.

They’re both great breast pumps so you can’t go wrong with either, but my personal choice is the Spectra S2.

How to use Spectra s1 and s2 breast pumps

When you’ve chosen your Spectra breast pump, you need to know how it works. I’ve written a tutorial on how to use the Spectra breast pump, but here’s a quick guide.

Both pumps come with identical parts, and they both also have the same button interface on the front.

Same parts:

Flanges
Duckbill valves
Backflow protectors
Tubing
Bottles

Same buttons:

Power
Cycle Buttons (+/-)
Vacuum Buttons (+/-)
Massage/Expression
Night light

Now that you have all your parts, here’s how to use the Spectra s2 breast pump (or s1; the same instructions apply):

Attach the duckbill valves to the bottom of the flange
Screw the bottle onto the flange
Insert the diaphragm of the backflow protectors into the base of the breast pump
Attach the backflow protector to the top of the breast shield
Connect the tube to the backflow protector at one end, and to the pump at the other
Turn on the pump and have it set to “massage mode”
Attach the flange to your breast
Begin at “Cycle 70/Vacuum 1” until the milk starts to flow
Once the milk is flowing, switch to “expression mode” at “Cycle 54/Vacuum 4”
Gradually decrease cycle speed and increase vacuum level
If milk flow slows, switch between “expression mode” and “massage mode” as needed
