# Mountain Buggy Carrycot Plus for Duet Luxury Double Stroller \| Out Of Box \| 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:* 43 checked facts, research depth trimmed read, checked 2026-10-19T19:31:57.264Z, in the [evidence pack](/agent/evidence/megababiesusa-com--mountain-buggy-carrycot-plus-for-duet-luxury-double-stroller-out-of-box). - **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](/agent/evidence/megababiesusa-com--mountain-buggy-carrycot-plus-for-duet-luxury-double-stroller-out-of-box). - **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 2026-10-25T19:45:44.134Z. - **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](https://robotrunk.com/products/ucp/megababiesusa-com/9001137471742.md). - **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](/agents.md). - **Research from other stores:** Coming soon: reading other stores' listings of the same product as new research sources.

The full evidence pack, with every citation, source and gap: [evidence pack](/agent/evidence/megababiesusa-com--mountain-buggy-carrycot-plus-for-duet-luxury-double-stroller-out-of-box) ## 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, blogs, owner forums and the recall records of CPSC \(United States\) and Health Canada and searched for regulator recall notices, owner reviews and video reviews. 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. - How thick and soft is the carrycot fabric in person? - Is the Herringbone fabric machine washable, and at what temperature? - What tools are needed to assemble the carrycot frameset? - What are the internal sleep\-surface dimensions? - Does the parent\-facing fabric include its own harness? - Does the small cut in the apron affect its waterproofing or footmuff use? - What is the warranty length for this carrycot? - Can the carrycot mattress cover be removed for washing? - Does the incline adjustment need any extra part or tool? - Is the carrycot compatible with Duet Heritage using an adapter? - How much does the carrycot weigh without the mattress and fabrics? - Does the carrycot need a custom sheet or a standard crib sheet?
