You do not need to move everything. Our general rule is: if you can vacuum around it, we can clean around it.
For insurance and safety reasons, we do not move heavier items over about 50 pounds, such as beds, dressers, entertainment centers, large tables, credenzas, or heavy specialty furniture. For sofas and smaller furniture, we can often clean in front, move the item carefully to clean behind it, and then place it back on protective pads while the carpet dries.
