1. Its a glossier style black diamond plate. Really smooth so it wipes up really easy. I usually clean it off with windex and a rag.
2. It weights like 700# or about 1 harley!
On the painted floor with no bike on it... it slides around pretty well. Plus as you can see the in the first slightly assembled pic of it... it came with a hand truck that helps roll it around on those wheels. Their real is to roll when the lift goes up and down.
3. The electric cords are just for the battery tender or my little heater (its cold here in the winter). The lift is 100% air powered.
