The World's #1 Vacuum Cleaner Advice, Repair, Discussion & Information Forum
It's also possible they left resin sourcing to the factories, so they might have gone from using a trusted European supplier to discount Chinese resins, but given Dyson's obsession with control over tooling, I think it's more likely that the badness of the DC40 and DC50 may have been growing pains while they moved to remote production.Of course, given the number of shattered V11s and V15s I see on eBay, with cracks in the same places as old DC14s, I'm not hopeful. Polymer parts can be stronger, lighter and tougher than steel in the same application, but it's rare that they actually are. If Dyson wanted to make vacuums to take a beating, we'd see frames made out of glass nylon or epoxy, and shielding made out of polypropylene. We don't see that, because tough polymers tend to be ugly, expensive, and hard to process, and they don't drive obsolescence sales. ABS and PC are fast, cheap, hold a mirror finish or glasslike clarity (respectively) and last a minimum of 5 years before showing oxidation damage. Sometimes, engineering is about bringing your performance limits down to match your warranty, rather than the other way around.
