I've worked on hundreds of sharks and I picked one up just to keep around my place after a fire took my old bagged Kenmore I bought new in 1984. What I've noticed with this specific model is how the dirt hose entrance is designed.
I have worked at an industrial steel fab shop that made cyclones and dust collection systems so I have a good idea of how this should
work. This model has a tendency to clogg at the elbow where the hose enters the cup. What happens if not due to the elbow or anything in size blocking it it's where the air enters the cup.
The upper part of the cup is basically designed to slow air down so the dirt can separate from the finne dust particles. But the hose actually enters into that upper cup area that has the screen separating the exhausting air tube from the inside of the dirt cup.
I never understood why they did this since anything that's large like a paper towel or let's say some larger solid items like a pill bottle cap will end up swirling around on that screened area and requires it to be cleaned out or everything clogs at the elbow before the entrance.
This design is flawed severely because it's blocking the main purpose for this entire type of system to work properly. Ther hose should enter below that upper screened cup and the air should swirl around and slow down while the entire time, the air is being drawn through the main exhaust tube going to the filters.
The large items should be on the bottom of the diet cup and not caught in the screen cup. Also there's no need for the fine dust to be sucked into the filters unless it's caught up in the turbulent air entering the dirt cup and that's fine that's how it should work. It should not be trying to suck anything but air into the filters for it to work efficiently.
So by entering right at the exhaust there's no way for large items to escape that screened cup shelf they have enacted as the separator. This is simply wrong. It's almost like they copied someone else's but didn't look closely at what it was meant to do and just drew it up wrong..
I have yet to use this thing without stopping constantly for clogs. I know they have a few changes they made to similar models that had an air straightener cell filter part that was encased in another plastic cage and it fit in the upper area.
My filters have larger particles collecting on top of the filter which might be a leak that occurs while the suction is high and the bypass valve opens, it flexes the bottom cover and allows dirt to enter right at the tune seal.
I've never had this with any other shark and I'm looking into how other dirt cups are designed , I have at least 5 other dirt cups from broken cased machines that I never repaired. The best has always been the shortest dirt cup models this model is the largest tallest in height with the highest full level marked as well
Has anyone tried to modify that screened cup area to have the dirt enter below it or next to it?. I would have to block off part of that screen cup to allow air to enter into the main body without any restrictions I would just use a hot knife and cut a flat area that I can glue a divider across that area i cut out. It has excellent suction and works fine unless large or heavy stuff is sucked into the dirt cup. A small pile of little rocks will fill up that screen cup quickly blocking the exhaust air and deducr suction. You'd think they would have seen this instantly I did!
The picture with the phone sitting in the screen cup area shows where I'd be cutting away the cup.
