How about this for a mammoth task? Experts are cleaning up a Blue Whale skeleton - the biggest creature on Earth - which is 27m long!
It's the first spring clean in 22 years for the 116-year-old exhibit at London's Natural History Museum.
A specialist team will take 120 hours sprucing up the Blue Whale and 25 other whale and dolphin models, while the museum's Whale Hall is closed.
The team will use 4km of scaffolding, 100m of bubble wrap, 10 special vacuum cleaners and 48 cleaning brushes! It makes tidying your bedroom seem quite easy!
