The Duo itself is cute. It’s less than half the size of the Spectra S1 pump. It measures 3.7 inches by 1.9 inches by 5.19 inches, and weighs a little over a half pound. It fits in one hand, and is brightly colored, with a backlit screen. Walking around while holding it feels like holding a Tamagotchi.
The tubing and power adapter ports are located at the base. It seems physically impossible for a pump this small to pack that big a punch, and yet it does. With its small, rechargeable 7-volt lithium-ion battery, the Duo is able to generate a maximum of 250 mmHg of vacuum pressure, which is comparable to much bigger pumps on the market.
Like the Spectra S1, the Duo is a closed system. A thin, white rubber membrane prevents milk from traveling through the pumping mechanism and into the rubber tubing. To pump, you turn it on and make sure that it’s switched to massage mode to stimulate milk production. When milk is flowing, press the mode button to switch to expression mode.
You can adjust the vacuum strength and frequency of the pumping. You can also save pumping sequences—when you hold the memory button, the pump will remember the vacuum strength, the time at which you switched to expression mode, and the length of the pumping session. The Duo also automatically shuts off after 30 minutes, if you get distracted or fall asleep while pumping.
Pump On the Go
I took the Motif Duo on a recent trip, packing it into my backpack for a flight and again on a car trip. I’ve also been using it to pump twice a day during my workday.
It took a startlingly short hour to charge fully, and each charge lasted a surprisingly long time. It advertises 2.5 hours of pumping time per charge; I’ve been able to go two to three days without charging, while pumping twice a day on maximum vacuum for 15 to 20 minute sessions.
Also startling: The pump does seem capable of the advertised 250 mmHg maximum vacuum strength. I max out the vacuum strength on every breast pump I’ve used. The Motif Duo seems comparable in terms of maximum strength—and correspondingly, output—to other pumps that I’ve tried.
As far as sound goes, I measured it at an average of 55 decibels. It’s not as quiet as a pump like the Medela Sonata, but you definitely won’t struggle to talk over it. And unlike other pumps, such as the Freemie Liberty, you can stick the bottles, flanges, and membranes into the dishwasher for washing and sterilizing.
I did have a few quibbles with the pump. It is frustrating that you can’t control both vacuum strength and frequency. When you increase the vacuum strength, the frequency decreases correspondingly.
Also, I didn’t find the memory function useful, which might be more due to my circumstances and physiology. I find that my pumping routine and output can vary tremendously, depending on whether or not I’m stressed out, distracted, dehydrated, or hungry.
In the weeks that I used it, I pumped in several different states, on planes and while riding in the passenger seat of a car. Anyone who needs a pump this small is likely to be in a similar boat. (I haven’t pumped in a boat yet, but I’m not ruling out the possibility.)
