I'm looking to upgrade my electric toothbrush and am considering an Oral-B iO series. What are the key unique features of the iO series that set it apart from other Oral-B electric toothbrushes, like the Genius series? Also, how can I tell when it's time to replace my Oral-B brush head, and where on the website can I find replacement brush heads for both iO and non-iO models?
Navigate to oralb.co.uk. Click on the 'Electric Toothbrushes' pull-down menu. Navigate to the iO Series collection page. Identify and list the key unique features of the iO series. Navigate back to the main 'Electric Toothbrushes' section or homepage to identify features of the Genius series (if available, otherwise note its general existence as another type). Click on the 'Replacement Brush Heads' pull-down menu. Navigate to a general replacement brush head page (e.g., 'Everyday Replacement brush head collection page'). Locate information on how to tell when a brush head needs changing (e.g., time frame, bristle indicators). Identify where to find replacement brush heads for iO and non-iO models on the website. Synthesize all collected information to answer the task.
The agent successfully navigates to the iO Series collection page. The agent identifies the iO series' unique features, such as 'Revolutionary Magnetic iO Technology', 'Interactive Colour Display', '3D TEETH TRACKING with A.I. to monitor brushing', 'Smart Pressure Sensor', and 'Magnetic Charger'. The agent identifies the Genius series as another distinct type of Oral-B electric toothbrush. The agent states that dentists recommend replacing brush heads every 3 months. The agent states that brush heads should also be replaced when bristles are faded or frayed (indicated by the blue indicator bristles fading halfway). The agent indicates that replacement brush heads can be found via links to 'iO Replacement brush head collection page' and 'Everyday Replacement brush head collection page' on the website.
