The cleaning appliances were taken sometime over the weekend between Friday 23 March and Monday 26 March 2012, when a heavy duty padlock which was securing the garage door on Coppice Gate, in the New Park area of the town, was cut off.
The offenders got away with an Ebac industrial humidifier, an Ebac air mover, a Steam Pro Power Max carpet cleaner, a Steam Pro Plus 2000 industrial steamer, a Sebo vacuum cleaner and a Pro Chem dry fibre machine.
Officers are appealing for anyone who has any information about the theft to come forward.
