Harmony® Breast Pump with PersonalFit Flex™ | live price, prepared checkout

Built for shopping agents: what RoboTrunk does for every product

We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built.

RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product.

• Deep research: We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read. check_product returns them with a source for each. This product: 29 checked facts, research depth trimmed read, checked 2026-09-25T10:47:34.086Z, in the evidence pack.
• Receipts: Every published fact has a receipt showing its source quote. check_product and get_product return the checked facts that have one. This product: each checked fact listed below has one; the source quotes are in the evidence pack.
• Safety: check_product asks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. This product: this page holds no recall result for it yet; check_product asks the regulators now.
• Recall watch: watch_recalls tells the buyer if a product bought here is recalled later.
• Second-hand listings: check_listing runs the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new.
• The real price: The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on: check_product and search_catalog take the buyer's country and postcode. This product: this store's price was read from its catalogue at 2026-10-18T19:50:07.465Z.
• A checkout that finishes: RoboTrunk lists only stores whose agent checkout it has verified. create_checkout prepares the order at the store; complete_checkout returns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs.
• Markdown copy: Every page has a Markdown copy: this page's copy.
• Photos and ratings: Search results carry the product photo and, where the store's own page publishes one, its rating (search_catalog).
• Fit answers: check_fit answers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known.
• Back-in-stock watches: watch_back_in_stock starts a watch on a listing the store shows as sold out; get_back_in_stock_watch shows when it is back in stock.
• Maker's manual: ask_product_manual answers from the maker's manual with the exact passage and page, or says the manual does not cover it.
• Tools and guide: Every tool and its description is at https://robotrunk.com/mcp; the guide is at /agents.md.
• Research from other stores: Coming soon: reading other stores' listings of the same product as research sources.

Checked facts

Each fact below was checked against the source it cites before it was published. Each carries that source's link and the time RoboTrunk read it. 29 checked facts, checked 2026-09-25T10:47:34.086Z. Research depth: trimmed read. Deep read: the store's own data and 8 outside pages (the store's own product page; maker page; manual; review; regulator recall search (CPSC (United States)); regulator recall search (Health Canada); regulator recall search (ACCC Product Safety Australia)), each read in full by RoboTrunk and trimmed to its main content, then written up and checked. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada, ACCC Product Safety Australia: The supplied CPSC search returned no Medela/Harmony records, Health Canada records mentioned no Medela products, and none of the 100 most recent ACCC recalls mentioned Medela or this model. The ACCC feed does not exclude older recalls outside that window.

• Best use case: Medela positions it for occasional pumping, travel or backup use; frequent pumpers may be better served by a double electric pump..

• Comfort and feel: The shield rim felt soft, smooth and flexible and sealed comfortably, but the handle was less hand-friendly, could become uncomfortable and its unintended rotation was annoying during longer sessions..

• Standard compliance: Medela's manual says the bottle intended for infant feeding complies with European Standard EN 14350; its mention of a teat concerns the separate Essentials Pack.. Source: https://www.medela.com/010-products/010-pumps/030-manual/010-harmony---manual-breast-pump/pdf-downloads/101041805-2021-05-b-harmony_flex_ifu_en_es_pt_ar_he-low.pdf (manual), read 2026-09-25T10:30:33.111Z.
• Efficiency: Testing found strong suction at times but inconsistent milk removal: small positioning changes could break the latch, the measured average was 0.13 oz per minute and maximum suction was 240 mmHg..

• Pumping controls: Use fast presses on the short side of the handle to stimulate flow, then slower full strokes on the longer side to express milk; stroke speed and compression control vacuum..

• Frequent use: The tester considered it better for occasional or backup use than regular double-breast pumping because operating it by hand takes longer and can cause hand fatigue..

• Assembly: Assembly is tool-free but requires correct placement of the membrane, sideways valve head, O-ring, diaphragm and stem to create a seal..

• Cleaning and assembly: Assembly was considered easy, but cleaning was relatively involved because there are about eight parts; the tiny O-rings are easy to lose and the pump may not work properly without them..

• Low suction: Low or absent suction can result from a missing or damaged O-ring, a poor breast seal, dirty or damaged valve parts, a membrane that is not flat, or incorrect assembly..

• Durability cautions: Frozen plastic parts become brittle and may break if dropped; dropping, overtightening or knocking parts over can also damage them..

The full evidence pack, with every citation, source and gap.

Questions we researched but could not confirm

Every fact above is cited. To find them we read the store listing, the maker's page, the manual, owner reviews and the recall records of CPSC (United States), Health Canada and ACCC Product Safety Australia. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess.

• What are the pump's exact assembled dimensions?
• How thick is the soft breast-shield rim?
• Does any printed finish or marking rub off over time?
• How long do the valve membrane and O-ring typically last?
• Are replacement valve membranes and O-rings available separately?
• Which regional sanitizing time applies to this exact retail unit?
• Does the 90-day warranty apply outside the United States and Canada?
• Will bottles from other brands fit the connector?
• Is a storage or carrying bag included?
• How much hand force is required at maximum comfortable suction?

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.
