I haven't. It would probably be easier. I tried with my little food processor . . . mess, mess, mess! A fork would have taken a tenth of the time to clean. I guess if you were making a lot you could use a potato masher . . . .
This morning I did, in a half dazed state. My youngest was up most night and I woke up before the rest of the house and realised I hadn't made any hummus for a party tonight. I starting mashing the chickpeas with a fork, it was hard work! That was before the coffee and common sense kicked in! Seriously, what was I thinking?
I have to admit to taking blenders and mixers to a bedroom and shutting the door to use them while we had people sleeping in the house. My mother-in-law even took the kettle to her room to make tea once so she would not wake us!
