Hm, You know, your measurement of 2” got me thinking, and I measured my head, and at the widest part across the bottom of the mushroom, Mine was like 1 3/4”, So you might be alright. The vacextender comes with a noose attachment too. I would recommend it, but I hesitate to tell anyone what to do with a chunk of money over $100. My gut tells me you would be fine with the vac head.
