Sanitaire S677 Type D Professional Upright Vacuum

This is my Sanitaire S677D upright vacuum (from 2007), that I bought on Ebay. I've always wanted to have a Sanitaire, I've seen theme all over in the Commercial line, I've never used one before this and I can already say, I'm very impressed with this machine. This is from the Professional line since it's colored in blue, while the red colored models are for commercial use. This was one of the top of the line Sanitaire's back them since it came with the fingertip on/off switch and the updated outer bag. It features a 7 amp (Eureka metal) motor with direct air design (and I believe it has the Quick Kleen fan chamber) and takes Style ST bags (In my opinion way better than the F&G bags that lower models come with). The suction is decent, but airflow is fantastic, and the agitation is amazing (being that this has a VibraGroomer 1 with 4 brush strips). My only complaints about this machine is that it's quite heavy and I hear that these stretch belts easily, but I haven't had any stretched belts on this just yet. I absolutely love this vacuum and would recommend this for anyone needing a new vacuum or one for commercial use.
