I've tried to design the Package so that it pretty much covers what you will need to get started. You might want to order some extra pads - maybe another ten or dozen - just to be prepared for an early large job. The Tile & Grout brush is only an additional $35, and will enable you to offer this service from the get-go. The sample pak of stain treatments from Vacaway that you also will receive should take care of things in this area, so you'll be pretty much good-to-go right from the start.
