The hosts failed to reach three figures with the bat in Durham as they suffered a 157-run loss to the tourists, and Root admits that the supporters deserve to see more from them at Old Trafford on Wednesday.
"We don't want fans turning up for games and seeing a performance like that," the 23-year-old told reporters. "It's quite embarrassing.
"We don't want to play like yesterday, where people come to watch and feel let down. We want to make sure everyone who comes in is impressed by what they see and want to come again.
"What we're expecting is to come back strong on Wednesday and show how good a side we can be. We should be able to win in these conditions."
The five-match series is currently tied at 1-1 ahead of the third ODI.
