Procter & Gamble’s push to add sensors and app-functionality to seemingly common household items continues here at CES 2020. From electric toothbrushes to fragrance diffusers to baby monitors, the old-school company is banking on smart homes needing some smart consumer goods. While many of the products showcased this year have been seen before, some that were in prototype stage last year have been refined, while others have only recently gone on sale.

The Oral-B iO electric toothbrush.

One new addition to P&G’s lineup is the Oral-B iO, an electric toothbrush with pressure sensors and what the company calls a “linear magnetic drive” — and the ability to learn from user habits and recommend improvements to brushing routines.

Marc Pritchard, P&G’s chief brand officer, also demonstrated one of the iO’s key features: a quiet motor that we had trouble hearing in a quiet conference room.

Alongside the heated Gillette razor we saw last year, P&G also showcased the Treo, a razor it says is designed for caregivers looking after loved ones.

The Lumi by Pampers Connected Care System has been shown before, and it was available to order last fall, but attendees will get a chance to check out the activity tracker/app/baby monitor combo up close here at CES 2020.

The $349 system includes an activity sensor parents can attach to their baby’s diaper, a video monitor, and a 10-day supply of diapers. The idea is for the sensor to build an activity record over time and help parents develop routines with their child.

“Lumi helps parents blend intuition with real-time data,” CEO of P&G Baby and Feminine Care Fama Francisco said.

The company also brought its Airia scent diffuser for some hands-on time at the show. Seen at last year’s CES, the Airia lets you control settings via app or Alexa-enabled devices.

Lastly, Pritchard also showed off a “cheeky” (their word) prototype for an app-controlled robot that can deliver toilet paper when you’ve run out and there’s none within arm’s reach.

Of course, not everyone necessarily needs or wants an activity tracker for their baby or an Alexa-enable scent diffuser, but it’s clear the 182-year-old company is trying to stay on top of tech trends, including the increasing popularity of smart homes, and the tech-infused devices that live in them.
