Vacuum Cleaners/Hoover U6470-900


My Hoover vacuum cuts off way to soon from heat overload.  Could you tell me what to look for, where the filters are, and where the overload switch is if I need to replace it.  Thanks..

Hello Ron and thank you for your question! Your Hoover has a thermal cut-off switch integrated into the motor.  It does not have a reset button.  It automatically resets after about 20 minutes.  If the reason for the thermal cutoff has not been resolved, it will trip again.
  The main cause of this is either a clog in the hose, or an overfull bag/dirty filters.
Please refer to for a parts breakdown of this unit to locate your filters.  One is under the bag in the bag compartment, the other is behind a door on the right side of the vac (as you are looking at it).  Remember the Hoover Y bag is also a filter.  Please do not reuse it, the pores of the bag will fill up.
  As far as a clog, I suggest you verify the attachment hose is clear by throwing a quarter down it.  See how quickly it comes out the other end.  If that hose is clear, look in the lower hose (#5 on the diagram) to ensure it is clear.
 Thank you again for your question, Ron.  I hope this helps.

Please ask me any questions regarding the efficiency, durability, and value of 99.5% of today's vacuum cleaners, residential and commercial. I am able to help, also, with your residential carpet cleaners and vapor steamers. I cannot answer questions such as "how much should I pay for my vac?" "how often should I change the bag, belt, filter?" or "how often should I vacuum?" , etc. I also will not advise you how to use equipment for other than its original application; including any disassembly or modification not approved by the unit's manufacturer.


I am the owner of a well-established (sixty-plus years), family-owned & operated vacuum retail and repair business. We are a full service/warranty center for 99.5% of vacuums manufactured. I, personally, have extensive hands-on experience with today's most popular vacuum cleaners, I have not only used the vacs in my own home, I have repaired them. I have been in the floor care industry for over 25 years.

I have attended certification seminars with the industry's trade association. My education, however, has been mostly hands-on, carrying on a sixty year old tradition in a brick and mortar 'mom & pop' location.
