Cielo, who holds the world records for the 50 and 100 metres freestyle, said the speedy times are now irrelevant given Fina's decision last year to ban all-polyurethane suits in competition from Jan 1.
"The times we did last year should be gone," Cielo said after finishing third in the final of the men's 100 metres freestyle at the Pan Pacific Swimming Championships. "It's just messing with everybody's head."
The decision to ban the high-tech racing suits was made by the sport's international governing body after 43 records were smashed at last year's world swimming championships by swimmers clad in the new-generation suits.
Only Camille Lacourt at the recent European Swimming Championships got close to a world record in the 50m backstroke.
Cielo set all of his top times wearing the high-tech racing suits that help reduce water resistance and increase buoyancy.
He set his world record 100 metres time of 46.91 seconds at last year's world championships in Rome and grabbed the 50 metres record of 20.91 seconds in December in Brazil.
"I don't see a reason to keep a 46.9 world record if we are barely breaking 48 (seconds)," said Cielo. "The most important thing is winning, not breaking the world record."
