You just need to replace the drive belt. https://www.google.com/search?q=eureka+optima+replace+belt+replacement ..

Question edited to clarity. Question moved to Eureka Vacuums from Health and Beauty. 25 Volts for similar models. Test it with a meter, it is more likely the battery has failed. https://www.amazon.ca/Adapter-Replacement-MC2508A-NEC-124A-CC170001A/dp/B081Z9DJZR ..

Remove water fill cap. Remove rubber washer under cap. Unscrew three phillips head sscrews, one on end of handle, two under rubber washer. Take handle apart. remove clip holding rubber hose onto steam flange. Unloosen plastic steam flange and remove. Using a large pair of pliers or channel locks gently squeeze valve together. It will only move an eighth to a quarter inch. Dove several times until you can depress the pin by hand. Reassemble.

you can check this link. I guess this should be helpful. If not, check for the related products underneath.

I am not sure about your "Boss", but a lot of vacuums have thermal cut-off switches built into the circuit so if the machine overheats from things like clogged filters/hoses the switch kicks in and kills power. You usually can NOT reset it manually ... you just have to wait until the machine cools down.

I no more use Eureka 4331 (Boss Lite). But the most common reason for not picking up dirt might be the vacuum bag might be full. Need to be Clean or replace as recommended by the manufacturer or The air filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner's manual for cleaning instructions. I recommend having Eureka Power Speed for yourself.

That sounds like a design feature and it the same as my Dyson. It stops you leaving it in one place with the brush turning. Google Eureka (model) Manual (or Review)

belt doesnt have to be broken, check the metal arm on the vacuum, see if there is build up of old rubber from previous belts, clean the arm that spins the belt and double check to make sure u have the correct belt

Boy, it's been awhile since I took one of these hoses off, but I think at least one of those plastic hose guide things has to come off in order to remove the hose. Those screws that look like they cannot be removed are probably torx screws which need a T20 torx scredriver that you can get at any hardware store. That is the most common size torx screw that Eureka uses.

Here is a link to the owner's manual in case you need any diagrams for getting the clear tubes off:

Hope this helps. :-)

Check belt

I think I know what the problem is with your machine. It's a rather lengthy repair, and I'll be happy to photograph it for you (like I do on most of my Fixya answers), but I'd like to know before doing all of that if you still need help, or if you've already fixed it.

Thanks,

Well documented issue, overheating, melted cheap wiring, cheap burned out switches made in China, a Dyson, it is not! Had exactly the same problem with my upright Eureka Model 5893 bagless. Eventually, the handle would get hot, and finally it just quit. When handle was disassembled, the wires were melted and it was toast. Ordered a switch after talking to several repair men. Talked to Eureka, too, and they were absolutely no help. Cheap wiring and switch made in China. Good luck trying to find a switch. vacuum-depot.com has switches, so you might try there, but make sure you get the 3-prong switch (same switch used on Eureka's Genesis). It is Part #27871. And lots more https://www.google.com/search?q=Eureka+vacuum+model%232961+Won%27t+start

Check for a reset switch.

You need to fill it with 2 cups

There should be four screws on the bottom that will allow you to take the hood off for cleaning. If the hood doesn't lift up check for other hidden screws. Sometimes they will hide them under wheels.

Check the belt

If the problem is the brushes aren't turning the belt might not have proper tension.

Make sure the hose is not jammed up with dust or it will trip the internal breaker.
