Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
My model number is actually U6425-900 but that doesn't come up in search....there doesn't seem to be any suction under the vacumn...when I disconnect the hose there is some suction..the hose that is curved and goes to the bottom of vacumn appeared to be clogged so I cleared that with a flexible brush but still no suction....can you help?
Make sure you have a good bag installed in the vacuum and the door is properly in place. Remove the attachment hose from the bag chamber and turn the machine on. You should have good suction coming from the hose inlet. If you don't you have a problem in the bag chamber. Bad bag, door is not on correct, door is defective, dirty secondary filter.
Connect the hose back to the machine and pull the other end out from the bottom, and turn the machine on. You should have good suction there. If you don't you have a clog or hole in the attachment hose and it needs to be unclogged or relplaced.
Reconnect the to the bottom. Flip the mahine upside down. Take the screws out of the bottom plate and remove. Remove the brushroller and belt. Turn the machine on and you should have suction at the inlet coming off the brushhousing. It you don't, then you have a clog in the nozzle hose and it needs to be removed. It will probably be more accessable from the bottom side since that is the way that it entered.
Sometimes a suction problem can be confused with an brush problem. The belts on that machine should be replaced every 6 to 8 months because they will strentch and wear. This is an inexpensive maitainance that will dramatically improve its function. Part Numbers are 38528-035 and 38528-034
