Where I work they don't have cleaning trolleys, so I have to carry a caddy full of chemicals, drag a cylinder hoover about and also carry a mop and bucket... the hallway is narrow so cannot even leave them in there so I have to leave them inside the rooms! I want to carry less stuff so would you just carry the caddy and hoover first then mop afterwards? There's a bathroom at the end of the hallway so I am thinking of leaving the mop and bucket in there till I've done one side of the corridor. 
random I know! I am quite organised and efficient but this baffles me and I want to get my work done properly without going to and fro.
