Remember always buy one that uses replaceable battery packs. Even better if you can just use a power tool battery. There are even adapters for certain brands of vacuums so you can put a power tool battery into the vacuum.
If the battery is not replaceable you have to trash the vacuum after a couple of years of use, since the battery won’t hold a charge. Replacing the li-on cells is not easy and requires a spot welder, you can’t just use a soldering iron.
Or worse yet, the battery is serviceable (barely, one has to completely disassemble the unit for access), only to find that a replacement costs almost as much as a brand new vacuum. The best part is, since there is usually little to no info online about the part number for the battery, one only learns of the cost until after one has taken on the challenge to take the damn thing apart (which definitely didn’t take 1-2 hours).
