Dyson V7 any way to run wall powered since battery life is so bad?

Dyson stick vacuums have terrible battery life on Max mode, even with new batteries. I can’t even do half my house at once. I would like to run it off wall voltage. However if you insert the plug into the vacuum even if the other end isn’t plugged into the wall it will not run. Is there any hack or workaround? If it could run straight off the wall transformer I wouldn’t need to buy a new vacuum.
