Barca have signed a deal to buy the service of a small cleaning company for a reported €5m, the Spanish newspaper Marca reports.
The club will pay €3.5m for the company, which has offices in the city of Bilbao and the nearby city of Córdoba.
The deal will be made public once Barca confirm its signing, Marca says.
The Spanish giants have been struggling to find cleaners in the capital, with some clubs only able to afford one service.
Barca’s signing comes as the Catalan club is considering selling its most expensive player, Neymar, in an attempt to shore up the finances ahead of the new financial year.
The Catalans are due to pay €30m (£25.7m) to buy Neymar from Barcelona for around £60m, with the remainder of the deal expected to be paid by the Brazilian club.
The Brazilian international, 27, has scored 27 goals this season and is the most expensive signing by a Spanish side this summer.
