I used the product to clean a condo that had really been neglected by a tenant. I used to clean the cupboard doors outside and on the inside. First you wouldn't the grime but using the Bissell, with a scrub brush it did the job. It was unbelievable They were brought back to looking new. Another area I used the unit was cleaning up a spillage that had been on the Bathroom floor for quite sometime. Again it did a great job. I also used it to clean the patio door, this attachment work very good and did remove what looked like years of cigarette Smoke. Also used the unit to remove dirt and grime that had built up in the corners of the floors, again great success.
