# How the Haakaa silicone breast pump generations differ How do the different generations of Haakaa silicone breast pumps differ? Haakaa Generation 3 Silicone Breast Pump: The Gen\. 3 pump keeps the original Haakaa design but lets you express straight into a detachable silicone bottle\. The Gen\. 3 gives the strongest suction of the Haakaa pumps compared in the video, and its top distorts far less, so the nipple is not pinched the way it can be on the standard pump\. Two capacities are offered, 6oz and 9oz\. Haakaa Generation 2 Silicone Breast Pump with Suction Base: A suction base on the bottom stops the pump falling over and spilling\. It arrives ready to use with no small parts and nothing to assemble\. The listing labels each pump's size as 4 oz \(100 ml\)\. Haakaa Generation 1 Silicone Breast Pump: A lactation\-consultant\-written review describes it as more accurately a milk collection device than a pump, using continuous vacuum to promote flow rather than actively pumping\. The Gen\. 1 is described by the maker as the world's first one\-piece silicone breast pump\. The pump holds 4 oz / 100 ml of milk\. ### 1.

(blog) Every value in the table is a fact RoboTrunk checked, linked to the page it came from\. A dash means no checked fact fills that cell\. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\. Written 2026-10-14T03:26:59.179Z. This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card.
