I'm looking to buy an Oral-B iO Series electric toothbrush and want to understand the differences between the iO™ SERIES 9 and iO™ SERIES 8. Can you tell me at least two key features that the iO™ SERIES 9 has that the iO™ SERIES 8 does not, and describe how their travel cases differ?
Navigate to the Oral-B UK homepage (oralb.co.uk). Click on 'Electric Toothbrushes' to expand the dropdown menu. Click on 'iO SERIES Collections Page link' to go to the iO Series product overview. Scroll down the page to view the features of the iO™ SERIES 9 and iO™ SERIES 8. Identify and list at least two features present on the iO™ SERIES 9 but absent on the iO™ SERIES 8. Identify and state the difference in the travel cases provided with each model.
Successfully navigate to the Oral-B iO Series collection page. Identify that the iO™ SERIES 9 has '3D TEETH TRACKING with A.I.' while the iO™ SERIES 8 only has 'Artificial Intelligence Technology' (or similar distinction in AI capabilities). Identify that the iO™ SERIES 9 has '7 Smart Brushing Modes' while the iO™ SERIES 8 has '6 Smart Brushing Modes'. State that the iO™ SERIES 9 comes with a 'Power2go Travel Case' and the iO™ SERIES 8 comes with a standard 'Travel Case'.
