My Eureka vacuum model 4471 does not pick up - the bag is new??

is filter dirty or bag full. (clean or replace) check for clogs

Check the belt. It may be slipping or broken. You can turn the vacuum over and turn it on briefly to make sure the brushes rotate.

If this is not the case, their may be a vacuum leak or something obstructing airflow, which is necessary to create a vacuum to pick up the dirt.

Good luck!

The model 4460 is for a Victory model which uses Eureka Type AA bags

They can be found at http://www.totalvac.com/eureka_aa_bags.html

Assuming this is a Eureka vacuum. Here is a link to Eureka T vacuum bags

Is the belt slipping. Are all the seals good

The problem is that your belt is stretched and worn. This causes that burning smell and it also causes the vacuum to not pick up well. You need to replace the belt. Here is the belt you need and the manual with instructions:

Below I have listed a link for your models manual which has instructions and a link for the belt you need. Hope it helps you!

Eureka 4471 Replacement Belt

There should be an toll free # to call for eureka and they can direct you to the nearest authorized eureka service center in you area. If its a new model places like wallmart wont stock it. There are so many vacuum makes and models its impossible for any one business to stock every single bag, belt, filter etc. for them all. But a decent vacuum repair shop should be able to get it for you.

filters are internal and if blocked will affect air flow. Check brushes in the foot not jammed or wrapped in hair

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.
