I suck better than them.

Cordless anything sucks inherently. Just use a cord nigga.

Vacuum suction strength and power efficiency don’t go hand in hand

It is their purpose.

>why do cordless vacuums still suck?
Because that's their job!
but yeah, I get what you mean. Vacuums in general are stupid. if you go corded, they're underpowered and you constantly have to change bags. If you wanna skip that shit and go shop vac you've just exchanged underpowered because underpowered with underpowered because filter is clogged, so you're now constantly cleaning your filter (and thereby inhaling all the shit you don't wanna inhale) instead of constantly changing bags. Maybe a really pro-tier one with cyclone and autoclean is better, but fuck spending 1k for a vacuum!
And "robots"?
You've either got some dumb machine that's bumping around your room randomly and you now have to spend the time you saved vacuuming with tidying up your room so the "robot" can do its thing, or you buy a smart one, but now even more of your life's details are in the hands of google, the CIA, NSA and a few more glowies, plus the CCP and it's various companies (but of course you still have to vacuum all the parts the robot can't do by hand).
