London, Jul 6 : Aussie singer Dannii Minogue is said to have made a peace offering to `The X Factor' co-judge Cheryl Cole by presenting her with a state-of-the-art robot vacuum cleaner.

Minogue, 37, gave Cole the 300 pounds Roomba Vacuum Robot at her 26th birthday bash in London's Vanilla private club.

And the effort to end the rivalry between them seems to have worked, with sources saying that the `Girls Aloud' member was "delighted" with her unusual present.

"Dannii's gift was Cheryl's favourite," the Daily Star quoted a pal of the star as saying.

"She thought it was hilarious and really thoughtful.

"She hates housework and can't get her husband Ashley to lift a finger in the house - so it showed Dannii had given a lot of thought to her gift.

"Cheryl gave Dannii a huge hug when she saw it," the pal added.

The cleaner's manufacturers claim that sensors guide the disk-shaped droid around any room, and that it can even adjust its own height to suck up dirt from different surfaces like rugs or tiles.

Other sources have revealed that the gift has proved that the girls have been getting along much better since their earlier stages of filming.

"Things may have been a bit frosty early on last year but they've got on so much better during this year's auditions," an X Factor insider said.

"Dannii has made a real effort to bond with Cheryl this year and it looks like it has paid off," the insider added. (ANI)
