After about 20-30 seconds of vacuuming it starts to make a really loud sucking noise. Yes, I’m sure it’s not just the regular vacuum sound. It almost sounds "sputtery" like it’s not getting enough consistent suction. I’ve cleaned out the rotating brush area and used my dryer vent cleaner as far as I could through the hose. It’s a Kenmore Progressive upright bagless 12 amps. Model number is 116 36933502 Thanks so much!
check the hose for a partial obstruction, possibly an irregular wad of paper, that has not made it through into the bag
you probably caught something in the hose,can you turn the hose around and pull it back out,
You need to get a vacuum cleaner that is simple to clean the insides. Try vacuum robot, it vacuums your carpet for you automatically, has a high suction power with 15 months Warranty, it’s hard to go wrong.
