A handheld sprayer (10′) includes a fluid module (12′) mounted to a drive module (14′) at a static connection (16′) and a dynamic connection (18′). The static connection (16′) supportably attached the fluid module (12′) to the drive module (14′). The dynamic connection (18′) connects a drive (84) of the drive module (14′) to a pump (24′) of the fluid module (12′) such that the drive (84) can power the pump (24′) by the dynamic connection (18′). The fluid contacting components of the handheld sprayer (10′) are in the fluid module (12′). The fluid module (12′) can be mounted to and dismounted from the drive module (14′) by a sliding motion.
