Obviously I like buying things once and for all, but I feel it’s extra difficult with anything electrical because I just don’t know that much about it personally, and I can’t exactly check the insides.
So lately I’ve been wanting to buy an upright vacuum. I don’t know if there are more durable brands, what kind of accessories I should consider to make my life easier, what budget I should consider, or what characterics are more likely to make it shorter lived than others.
Well the minimal bars for electronics is:
0 - The repair manual exists and is readily available with full schematics of the item in question.
1 - Replacement parts are available for purchase.
2 - Compatible replacement parts are made by 2 or more 3rd party companies
3 - Designs for replacement parts are available
4 - Local maker space is able to make the needed replacement parts.
If you can’t get level 0, you probably shouldn’t buy it if you expect to keep it working for life.
