I'm looking for an alternative replacement hose since the original has been discontinued

The hose assembly model number 11621714110 is a genuine OEM (Original Equipment Manufacturer) part for use with a variety of appliances, including vacuum cleaners and washing machines. This hose assembly may be used to connect various parts of the appliance, such as the pump and the tub, or to connect the appliance to a water source.
I hope this information is helpful! Let me know if you have any other questions.

Here is a link to hoses that will fit your unit. You did not say if it was 1 1/4 or 1 1/2 inch fitting so this page covers both sizes.

Here is their site, it looks like the canister vacuum is discontinued.
If this is not adequate information, you can find several contact options on this page.

according to the schematic it doesnt look like you can take that coupling apart. Usually when one has a problem with an electric canister hose its just easier to replace the hose because trying to shorten it without damaging the internal electrical wires and reassembling with the hose working is very unlikely. the hose part # is 43433113. you might have a hard time finding it tho. that hose was discontinued on 1/09 (same time that dirt devil bought out hoover and moved them over to china.) if you need anything else feel free to let me know.

The early hose on these was prone to tearing. If you are careful you can shorten it once. Beyond that it will become too short to use on the vac properly. This hose was copied from the original Black and Decker hose and power head kit and was likely upgraded by a flex vinyl molded hose which should be more resistant to tearing.
Some vac shops carry hose "refills" and a Samsung dealer may have one in stock even if the hose was discontinued. The vac is good quality in its general design and worth fixing although the original diameter of this hose may be tough to match

I filled a bowl with hot bleach water and sucked the water up. It cleaned the hose pretty well (along with the gunk that was stuck in the hand wand). Mine was filthy. It looked like it had mold growing in it. Then I ran several rounds of hot water through the hose. I alternated hot water & bleach. Did this about 8 times. It is not perfect, but it sure does look a lot better. 90% of the gunk is gone.

Usually the older hose get replaced, they just weren't made to be repaired, if it looks like something that will come off, then try either warming the sleeve up with hot water or a hair drier to see if you can work it off after it has warmed up.
