Difference between Spectra S1 and S2
The detailed Spectra 1 vs 2 report clearly shows how both are somewhat similar with only minimal differences. If an in-built battery is mandatory for you, go for the Spectra 1 and if you can do without one, buy Spectra 2 at a great price.
How to Use Spectra Pump
Let us go through this step by step.
Step 1
The first step is assembling. According to both Spectra S1 and Spectra S2 Reviews assembling is pretty easy. Just be familiar with the parts of the Spectra breast pump. Put the flanges, valves, protectors, and tubes together to begin.
Step 2
Turn the power button on and adjust the speed to whatever you are comfortable with. The cycle buttons control the speed. Then regulate the vacuum level to how strongly you want the machine to suck. It is recommended to start vacuum at a low level and gradually increase it. This is one of the most important breast pumping tips.
Step 3
Switch to and fro from massage and expression mode according to your comfort in the process.
Step 4
Collect the milk and store it in sterilized bottles. After you are done, detach the parts and place them carefully in the best breast pump bag.

How to Clean Spectra Breast Pump
Cleaning the breast pumps is pretty easy. After every use, wash all the parts in soapy hot water except the tubing. Make sure it is lukewarm water as hot water could damage your equipment.
Use a dishwasher to wash the detachable parts. Remember to put them on the top shelf only. Again do not include the tubing in your washing process.
Use a damp cloth to wipe the dirt off your pump. Do not put it directly into the water. Also you can sterilize it (however, complete sterilization can’t be achieved at home).
If you are to go through any Spectra S1 review or even , you will see cleaning the devices is no rocket science.
