There has been a growing outpouring of solidarity in and around Valencia to help those affected by catastrophic flooding.
Organisers believe at least 15,000 people showed up on Saturday morning alone for the first coordinated clean-up.
Spain's prime minister, Pedro Sánchez, has said 211 people have been confirmed dead, with the toll expected to rise further.
He has ordered 5,000 more troops and 5,000 police officers and civil guards to the Valencia region as residents criticise local authorities over their response.
