I'm interested in purchasing a new Oral-B electric toothbrush and want to understand the different types available, especially the iO series. Please find out what makes the iO series unique and identify at least two other distinct types of Oral-B electric toothbrushes mentioned on the website. Additionally, locate information on how often I should change my brush head and where I can find replacement brush heads.
Navigate to the Oral-B UK homepage (oralb.co.uk). Click on the 'Electric Toothbrushes' pull-down menu (ID 195). Look for information about the iO series and identify its unique features. Identify at least two other distinct types or categories of Oral-B electric toothbrushes. Navigate back to the homepage or a relevant section to find information on replacement brush heads. Click on the 'Replacement Brush Heads' pull-down menu (ID 204). Locate information on how often brush heads should be changed. Synthesize all collected information to answer the task.
The agent successfully navigates to the 'Electric Toothbrushes' section or a page detailing different models. The agent identifies what makes the iO series unique (e.g., micro-vibrations, interactive display, AI recognition). The agent identifies at least two other distinct types or categories of Oral-B electric toothbrushes (e.g., SmartSeries, Genius, Vitality, Pro). The agent successfully navigates to a page with information about replacement brush heads. The agent states how often brush heads should be changed (e.g., every 3 months or when bristles are faded/frayed). The agent indicates where replacement brush heads can be found or purchased (e.g., through links on the website).
