Question about Hoover S3765-040 WindTunnel Bagless Canister Vacuum
It turns fine on hard surface, but on some carpets it just stops rotating and at least one time the motor threw the belt off so I needed to put it back on. It supposed to adjust "automatically" to the length of the carpet but it certainly doesn't. Kind of unexpected for a brand new vac (just got it yesterday). Ideas?
That all sounds very reasonable, except it wasn't the belt that was having problems turning the brush -- it was the motor itself. All that mostly happens on one particular carpet in my house, made of a pretty hard material. I didn't want to completely kill the motor and finally wound up trimming the bristle a bit. So far, it appears to be working.

This machine needs a new belt. The belt is stretched into position and even if it is not used, will fatigue over time. This can occur as the machine is in storage waiting to be sold. If you check the bristle on the roller, you will observe that it extends out the bottom of the powerhead quite far and is very stiff. This causes the brush to engage the carpet very aggressively and puts considerable strain on the belt. A tired belt will fail very quickly under these conditions. You should take it to a warranty depot and have the belt changed.
This machine also has variable speed motor in the main unit. This is so you can adjust how heavily the powerhead brushes the carpet. If it is set too high, on certain carpets, the suction will pull the powerhead down too hard and this will bogg the roller and cause the belt to fail prematurely.

• The brush bar will always default to 'ON' (spinning) each time you switch the
appliance 'ON' and recline it for cleaning.
• The brush bar will not rotate when the appliance is upright.
• To switch the brush bar 'OFF' (e.g. for delicate rugs and hard floors):
- switch the appliance 'ON'
- recline the appliance
- press the brush bar 'ON/OFF' button - the brush bar will stop spinning.
• The brush bar will automatically stop if it becomes obstructed. See 'Brush bar -
• Before vacuuming your flooring, rugs and carpets, check the manufacturer's
recommended cleaning instructions.
• Some carpets may fuzz if a rotating brush bar is used when vacuuming. If this
happens, we recommend vacuuming in 'hard floor' mode and consulting with
the flooring manufacturer.
• The brush bar on the appliance may damage some carpet types. If you are
unsure, turn 'OFF' the brush bar.
