I'm able to walk without it so this may or may not work for you. Going into the room, I positioned the
ECV pointing towards the door. Put it in neutral via the lever in back. Unlocked the door. Pushed it open a little. Turned around and while pushing the door open with my bum, pulled the ecv into the room.
Going out, I positioned the ecv with the back of the seat pointing towards the door. Opened door. Pushed ecv out. Then flipped the latch on the door so I didn't accidentally lock myself out of the room.
