How often do I have to reprogram Whiz?

Once you program Whiz to clean a route, you never have to reprogram Whiz. As you make small changes to the environment (for example, if you change a piece of furniture) Whiz will adapt to the new environment. However, if you make significant changes to the environment (restructuring the layout, adding significant and additional obstacles) it is recommended to reprogram the route for maximum efficiency. As you get better at route mapping, and learn more about your unique traffic patterns, you may uncover more efficient mapping techniques, and decide to remap an earlier route to gain efficiency.
