A trigger actuated cleaning device includes an adjustable retainer assembly for alternately holding a full-size or compact aerosol spay canister, thereby allowing the device to be used as a mop with an extension wand and a large canister or a wandless hand-held device with a small canister. The retainer has a “ski-boot” configuration with a heel assembly slidable on a fixed rail having a spring biased latch engaging the rim at the bottom of the canister and clamping it against a toe stop, which is configured to align the canister with a trigger operated actuator. The heel assembly slides and locks in position for either a full-size or compact canister to snap into the device. The canister is removed by depressing a thumb operated release lever which clears the latch from the canister.
