Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.
My vacuum cleaner. You know how the roller brush gets all tangled up with hair and threads and whatnot, and the way you fix that is to remove the roller and cut it all out?
The external screws are torx security bits. The internal screws are Phillips. The only reason is to get someone who isn’t persistent to go buy a new vacuum cleaner when their roller gets tangled
Name the brand so we can avoid
At this point I think at least a modest tamper kit should be in a household the same way a screwdriver was previously.
I just pull the hair directly off the roller as is. No need to take it out. I clean it often enough that it would take more time to take it off no matter what screws it has. The worst part imo is the internal screws being phillips. Torx (whether “security” versions or not) > Phillips/Flathead.
Pro-tip: cut the hair along the roller with a knife. Don’t have to unwind it more than a single turn this way.
