Yes you can very easily remove the suction bit and the cable. I always leave it unless it gets in the way, it sucks pretty good. When it gets in the way I remove the bit only, which is super easy to do and leave the cable so I can put the suction back again. Just don’t expect it to be a replacement for an actual good fume extractor, I always use both a dedicated extractor as well as the ventilation in my office/electric workstation. Breathing solder fumes is pretty bad in the long term.
