Hi Sorry to hear that.
Usually the vacuum in this case will need a good cleaning and if it was used extensively may need new bushings on the motor shaft.
This is something best done by any local vacuum shop
The screeching is work bushings, they aren't very expensive if they are available and likely your local guy has them. If he cant get them he may want to replace the motor.
But this really is a basic service for these vacs:-)
They just need a little TLC every now and again lol.
SO a simple tune up is all that's likely needed.
But I will be here for you if you need me further at no additional cost to you.
Since you may need me further, if you will rate my service as good or betterbefore you close this window, the system here will allow me to schedule free follow ups with youso your question wont close or time out and you can contact me anytime at no additional cost.Thank youTech Michael
Thank you Mike, as my wife is a clean freak, I will be most likely taking this vac in for that service this week. I had a feeling myself, but needed that little push from a 3rd party..........thanx
Please don't forget to rate my service, I will still be here for you and will schedule free follow ups with you:-)
Have a great evening!
