Mighty Tyke Duo Features

The Rumble Tuff Mighty Tyke is a closed-system, double electric breast pump intended for daily personal use. This lightweight and compact pump is easily portable for mothers on the go, and the powerful motor is capable of delivering strong suction power to help you complete your pumping quickly and effortlessly.

A built-in lithium-ion battery makes it easy to pump wherever you are, whenever you need. A rechargeable lithium-ion battery provides a low-cost, low-maintenance alternative to traditional alkaline batteries. This pump can also be converted into a manual breast pump (Manual Pump Diaphragm Kit not included).

The built-in belt clip of this powerful little pump provides you with more freedom and greater mobility during your pumping sessions. The simplified control panel allows easy access from all angles, whether the pump is stationary or clipped to your side, and an LED display makes it easy to view your pump’s current settings at a glance.

With the Swift Expression and Natural Expression patterns and adjustable suction, the Mighty Tyke is designed to help you best match your baby’s natural nursing patterns. The customizable settings allow you to choose the most comfortable and effective vacuum strength for you. The Swift Expression features 8 levels of suction, while the Natural Expression has 9 levels to choose from.

The Mighty Tyke Duo Electric Breast Pump comes with a 120-day limited warranty and a 1-year extended warranty for the pump motor (wearable accessories excluded). Warranty information can be found in the User Manual.

BPA free.

Included Accessories


Anti-Backflow Diaphragm

The Mighty Tyke Duo is designed with a closed-system diaphragm which prevents any milk backflow. While milk flows freely into the collection bottle, the diaphragm acts as a protective barrier, preventing any milk from leaking into the tubing or electric motor.
