Here is my Hoover Self propelled Wind tunnel with dirt finder in action. This is a very nice powerful vacuum that actually has a transmission on it to pull itself forward and backwards. It also has a dirt finder light that tells you when your carpet is dirty or clean. Unfortionatly it is very loud.
Could you make a new vid of this and post it?
It sounds like ur vac is dying
i did it in winter, it was in the back of my suv for a week and was kinda frozen. I’ll dig it out and make a new one soon.
Not a healthy sounding cleaner
