This kinda fits an old Electrolux Ergorapido wireless vacuum cleaner (model markings: CT180LI-BRC, ZB 2941). Some trickier dimensions are eyeballed, but it can definitely work if you figure out a way to reliably attach it to the motor.

I did not succeed in repairing the vacuum: something still needs to be done about securely attaching the impeller to the motor. Friction alone gives you maybe 5 minutes of work before it's dislodged. I tried positioning the impeller on the spindle, heating up the center with a rework station and pressing the middle of the central cylinder with angled tweezers to take advantage of the narrow middle section of the motor's spindle. In hindsight it's probably better to just use a soldering iron (maybe with an angled tip) to press the middle section in, as hot air gun can make the impeller's base wobbly before the central cylinder becomes pliable. Either might work for you, but personally I broke the motor in the middle of my experiments and won't see this project through :)

(on breaking the motor: the metal piece on the motor's spindle looks like a threaded insert you would normally melt into plastic with a soldering iron, so I thought if I can unscrew it, the task of securing it inside the impeller will be much easier. DO NOT try to lock the spindle by lodging something into the motor through a side hole, you will likely break the wiring on the coils)
