If that fuse blows, does swapping it help? Wouldn't the blown fuse typically mean the fan bearings are broken and a new fuse would just blow soon again?

i my case I shorted it and have been using the vacuum for another 10 years. there was dust in the fan bearings, but i sluiced it out with mineral oil.

  So, the end result of having a soldered fuse was exactly the same as a socketed one: it was successfully repaired. I don’t see the justification for the extra BOM item. For the 99% of people who don’t attempt electrical repairs on their vacuums, that fuse socket would be sitting inside of a vacuum in a landfill. Drive around any US suburb on trash night and pick up a couple of appliances. Most of them either still work 100% or have trivially fixable issues. People (US consumers especially) don’t fix stuff. Don’t get me wrong, I love fixing things myself. I’ve probably saved $10,000 over the past 5 years by fixing things people were throwing away instead of buying. The ease with which this is possible to do demonstrates how few people attempt repairs themselves.

    >So, the end result of having a soldered fuse was exactly the same as a socketed one: it was successfully repaired. I don’t see the justification for the extra BOM item. You joking? You realize houses and cars have socketed fuses that can be replaced almost turnkey. This is a simple solution to build into the product a UI that let's the user know a socket was blown and allow the user to replace a fuse like replacing a AA battery. FUSES are designed to fail and be replaced. Making those FUSES inaccessible is ALSO a design choice because it's contradictory. There was a point in time where every phone had a replaceable battery. You think that replaceable batteries disappeared because companies wanted to save costs? Sockets for batteries have been part of the design philosophy for consumer products for decades, the fact that these sockets are removed from phones is not a cost saving measure. This issue is much more widespread than you think: https://www.youtube.com/watch?v=SrDEtSlqJC4 https://www.youtube.com/watch?v=SrDEtSlqJC4

      My above point is was that cost is an example of an engineering tradeoff, not that it is the only engineering tradeoff. Phone batteries are designed to be replaceable. They’re internal because of design considerations, not cost. In fact, nearly all cell phone batteries are secured with removable adhesive because they’re specifically intended to be replaceable. Homes have circuit breakers (fuses haven’t been mainstream for a while) because the load is not predefined, and can be occasionally exceeded by the end user. This is not the case for a consumer appliance with a known load. An unexpectedly high load is an indication that another component has also failed. There’s some diagnosis that should be done when replacing a fuse on a system with an unexplained over current situation.

        Your logic doesn't make sense for why socketed fuses even exist. So why do cars have socketed fuses then? Do cars have unexpected loads? Not nearly as much as houses. Cars have socketed fuses same as houses because fuses are designed to fail and be replaced. This is the logical intention of fuses. Making something that is designed to fail and be replaced (fuses) inaccessible is a contradictory design philosophy... Unless this design philosophy is INTENDED to make the product fail. You place a component designed to fail inside a vac and make it inaccessible then that means you are designing the vac to fail. Phone batteries are not designed to be replaceable this is a lie or pure stupidity. You realize that glue or adhesive is not designed to be removed right? It's designed to be permanent. Screws and socketed components are designed to be removed. Additionally the iPhone isn't even designed to be opened. It's extremely hard to open that device and it's completely obvious the reason is because that device is designed to both fail in a certain time frame and only be serviceable by apple technicians. Here's how easy it is to "replace" a battery you claim was glued into the phone as a design decision to be "replaceable": https://youtu.be/gkCyl7kRGns https://youtu.be/gkCyl7kRGns >My above point is was that cost is an example of an engineering tradeoff, not that it is the only engineering tradeoff Who in the universe isn't aware that tradeoffs outside of cost don't exist? Kind of useless if the point is to obvious. How about you address my point in the fact that deliberate decisions were made to make products fail and that these failures are not design tradeoffs. A thinner phone for an irreplaceable battery in the iPhone is not actually a tradeoff. In fact if you look inside the phone they very much could've screwed the battery in without increasing the thickness of the phone. You realize that Steve Jobs once said the iPod was designed to only last a year?

  Aren't you worried about the fan stalling and catching fire?

    eh. even if it takes you a few seconds to wonder why its not spinning up they usually dont burn out right away. and if they do there is a little puff of smoke, nary even a pop.
