So here we go. The Sanitaire Tradition Wide Track Upright Commercial Vacuum Cleaner, SC899H comes in a standard size box. Completely disassembled. Now this is the DUMPING BAG model. So go to the right page. Pro tip: YOUR CABLE must be inserted into the gray cable holders before you snap them into place. And all of this can only happen in one way. So there may be some sort of reassembly. All in all, the assembly is NO problem next. You need to find and watch an actual video on how to empty a garbage bag. THERE IS NO INSIDE THE BAG - THATS IT - REMOVE and discard the bag. Take it outside, put it half back on and REMOVE dust from all sides. Then clip the top into the silver clip. And THAT is the BAD AND disgusting part of this vacuum. Throwing it away is TERRIBLE. And it's awful because it's such an incredibly powerful suction cup that you pick up every molecule and particle on the floor. AND IT'S GOOD - I have a Kirb. My pride and joy. There are two Mieles cars nearby, three Dysons and so on and so forth. I KNOW VACUUM CLEANERS. When I collected this beast and took it with me on my first trip, I was a little amazed. A lot is gone. THIS VACUUM IS MORE POWERFUL THAN MY KIRBY AVALIR - WHAT?!?!?!? Yes, that's right. I tracked down a few test looks and confirmed it. A believable story. Now more about what's great - the ALL CHROME hood. You don't need any tools - just a screwdriver - it doesn't matter which one - both work. An air motor so damn powerful you really need headphones. Seriously LOUD. For example Mieles, very quiet. Plumbing - VERY LOUD! After reviewing the steps I had to take to review this model, I found that my ears really hurt. So, PLEASE hearing protection! 50' cable. But the cable holder does NOT open, it has to be unwound manually, which annoyed me. BUT, if you have to suck up miles every day, you'll LOVE LOVE LOVE when you have 50 feet of cord to work with. Now WIDE nozzle. Works consistently, sucks across the entire width. If you have tons of flat rugs with minimal or industrial furniture (wider bases), this isn't a problem. For office work this can be a real problem, not a time saver. Because the head is more difficult to guide through the chair legs. You must also always remember to get out of the room you are trapped in because this vacuum cleaner DON'T TURN A PENNY! So no zoning. Miles of carpets in hotel rooms - PERFECT PERFECT PERFECT. Watch your settings or you'll pick cheaper rugs straight from the upholstery. NO JOKE! After all, it's a beast. It weighs a ton. It looks old fashioned and NOT FINE. It's poorly made. This is NOT a GERMAN sports car. It's a sucking beast. Beautifully surrounded by plastic bumpers. You will need them until you learn to drive. Works FANTASTIC well. He is more powerful than Kirby. Waste is a nightmare. I would go with the bagged version of this vacuum to throw away the bag. And finally, NO HEADLIGHTS. Still, the power is so great that I can ignore all of these things (except for the bag - I'll have to get used to that bag). Therefore 4 stars. A HEPA bag is required to get five stars. On my wish list for this vacuum would be a power cord, headlights and a little more maneuverability. Here it is. Hope this helps you decide!
