How we reached each verdictThe numbers behind each model's score
Oral-B iO Series 9
Experts rate the iO Series 9 highly (score 88), and all 8 hands-on reviewers praise its cleaning. Owners are cooler (score 71), and reliability is the weak spot at 32: 27% of owner comments mention failures, 16% say the brush broke or died, and 24% of retail ratings are 1-star. Battery life is the biggest split. Experts reported anywhere from about 10 days to 38.5 days, and 20% of owners complain about the battery while only 3% praise it. The evidence is solid on cleaning, based on 175 owner comments (151 first-hand) and 9,395 retail votes, but less settled on long-term durability.
Oral-B Pro 1000
All 4 expert reviews were hands-on, and the clearest finding is cleaning power: every expert rated it at least decent, and 61% of 299 owner comments (269 first-hand) praise how well it cleans. Value is the other strong point, with all 4 experts highlighting the roughly $50 price and 13% of owners mentioning value, while only 2% of owners report a unit breaking and 6% mention any failure. Experts split on battery life (two measured roughly 10 to 12 days; one six-year user calls it long-lasting) and on gentleness (Forbes says it suits sensitive gums, TechGearLab found it too harsh). Only 2 experts published scores, so evidence is solid on cleaning but thinner on long-term durability and comfort for sensitive mouths.
