Hey Tom, first, thank you so much for reading the article and expressing your approval of it. It means a lot to me that the information posted on this site is useful for the people. To your question about pellet grills, yes. You must always use BBQ grilling pellets with these cookers. You cannot use raw wood with them. However, should you find yourself with access too hard woods like Hickory or maple, or fruit woods like apple, cherry, or peach – this is something that could be readily used in a charcoal smoker.
The biggest cleanup issue is the buildup on the heat deflector under the cooking grates. You'll need good gloves and an apron. On most models, a thorough cleanup means a 30 minute process of taking out the greasy grates and the gooey deflector plate, scraping them and washing them. You should do this when the carbon and grease cover the deflector plate. Stainless parts can go in the diswasher, but I wouldn't do it. That grease is like tar and it could get all over the insides of the dishwasher and hang on for dear life. I use a handheld steamer like the Steamfast SF-320 Portable Steam Cleaner shown here.
What makes it stand out from the crowd is that it’s the only pellet grill on the market (so far) that has an ash cleanout system… no more hauling out your vacuum to the patio to suck out the ashes when it’s time to clean out your grill! You just need a small cup… and with a simple turn of a small lever, the ashes drop out! You’ll LOVE this feature!
Most grills feature a primary cooking area (the main grate) and a secondary cooking area (additional racks). In a pellet grill, there’s less difference between the two grilling areas because it mainly cooks by indirect heat, so the temperature is the same throughout the grill. It’s best to pay attention to a pellet grill’s total cooking area because it is the sum of the primary and secondary cooking areas.
