You are obviously doing WAY too much house work! And need to spend more time with your feet up relaxing ;)
Seriously, I’ve been noticing the lack of quality in most things I’ve been buying, from socks to washing machines. The same brand socks I’ve been buying for years are now much thinner - I have old pairs from 5 years ago to compare with. And our old Kenmore washer lasted 25 years and the new one is so chinzy, all plastic parts, that I hope it lasts a bit longer than the warranty. Your vacuums are probably the same way. ;(
We have the same problem with socks. I got some Gold Star socks from Penneys....expensive, but thicker. ;0(
I know exactly what you are talking about. I have a clothes dryer that is almost 30 years old. And it's STILL going strong.
