I use the Shark Navigator Lift Away. You can train a rabbit to get used to the vacuum. Just watch their body language. In the beginning, I would put Trixie in her crate and carry her into the other room. But after weeks of doing that, I thought I'd try out the vacuum with her there. I have a corner in my room where her tunnel is and I would put her in the corner - furthest away from the vacuum. I would turn it on and sure enough, she would scurry into the tunnel (which is her safe zone). After I'm done, I give her a treat. She's now gotten used to our routine. Of course the initial sound of the vacuum still scares her, but after she realizes that sound, she isn't bothered by it. In fact, she's now gotten confident enough to where she's actually gotten close up to check out the "oddly shaped rabbit".
