Easiest smoker to clean

Just spent 2 hours cleaning my Zgrills smoker. If I ever upgrade I would want one that is much easier to clean. Is there a model of pellet grill out there that is dead simple to clean? One that doesn't require using a wet dry/vac to vacuum and scraping and scooping out the grease. Does anyone have one that they love using that also is a breeze to clean and maintain?
