Pet messes know no limits. The fact that this can only be used on horizontal surfaces is a bit limiting when messes happen down the back of the couch cushions or on the kickplate of the steps. The power cord also does not appear it will withstand pesky cat cord chewers. The cleaning power when using as instructed, though, is outstanding. Would recommend this but would also urge Bissell to update the quality of the cord and the ability to use vertically.
