In one embodiment, a handheld laser treatment apparatus comprises: a handset including a treatment chamber, the treatment chamber having an open treatment aperture; a laser array arranged to project optical energy into the treatment chamber and coupled to a power source; at least one vacuum channel positioned within the treatment chamber and coupled to a vacuum source; a trigger sensor coupled to logic that controls activation of the laser array and the vacuum channel; an attachment sensor arranged to detect which of a plurality of attachments are inserted into the treatment chamber through the treatment aperture. The logic enables activation of the vacuum channel when the attachment sensor detects a first attachment of the plurality of attachments inserted into the treatment aperture. The logic disables activation of the vacuum channel when the attachment sensor detects a second attachment of the plurality of attachments inserted into the treatment aperture.
