Be random with your strokes, make figure 8's and 4 leaf clovers type passes. Back and forth can create streaks on some piles.
ALWAYS groom/wand out the room before you move on to see if you missed any areas. PITA to come back in once you are on the other side of the house.

Check jets often for plugs/blockage
Don't fook around on glue downs.
Be aware of where seams are located and don't sit on them for too long, the intense heat will loosen the glue.
Run two inch hose all the way to the head.
Don't whack any tile or wood transitions. Practice your approach with a helper watching, it's hard to see just how close you are.

Call Marty a hack as often as possible.
