DMX Vacuums Nightclub -- The Clean Streak Continues! [VIDEO]

Just days after mopping up at a Waffle House last week, DMX was once again spotted cleaning up his act -- vacuuming the carpet at a nightclub in South Carolina ... and TMZ has the video proof.

As for what prompted the latest cleaning spree at Club Universal in Spartanburg Saturday night -- X tells us, he just loves to clean and if he can help out the people who do it for a living, all the better ... "Broom, vacuum, mop, whatever ... it's a rewarding experience."
