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.
