How does one get the belt off of the FM625H? My

Have you checked the drive belt on the pet head? Mine comes apart and a thin belt is driven by the propellers which in turn drive the brush head via the drive belt. To check turn propeller and see if brush head rotates if not belt missing broken / jammed

You have already removed the screws so lift the brush cover off. Then grasp rotating floor brush at both ends and lift. Clean strings,hair and other debris from rotating brush, paying close attention to the brush ends. Clean the debris from motor pulley and drive belt areas.Grasp old drive belt and remove from motor pulley. Place new drive belt over motor pulley and stretch other end over rotating floor brush in the space between the bristles. Place the ends of the rotating floor brush down into slots on the sides. Turn the rotating floor brush by hand several times in the direction of motor pulley. If installed properly, drive belt will center itself on rotating brush. Reposition brush cover and screw back into place. I hope that this helps you!

You need to replace the belt. You can get Fantom replacement belts here:

I took the top of the vacuum apart and found the cable that drives the wheels was broken. I am going to order a new cable.

Remove the glide plate at the bottom of rhe machine. Remove brush and broken belt. Fit new belt and re install brush. Fit glide plate, job done.

The rod must be your brush roll. it should just pull out, Have you removed the cover over the brush roll? When you do get the brush roll out, turnb the ends and make sure they turn freely, if nit, replace it also.

Sounds like you have broken belt. I had the same thing happen, Got replacement belts, but can't figure out how to get the smaller belt back on. There two larger belts - one on each end of the brushes under the clear plastic covers. On the left side there a single silver metal gear, but nothing to hook up the other end of the small belt to drive the brushes. If you take yours apart let me know how to hook up the smaller belt.

Thanks,

There is no belt, the brush block is turned by a turbine. Check the brush block, make sure that the shaft that goes into the turbine isn't broke off, If ok, then replace the turbine, or take it apart and clean it out.

Hoover steamvacs don't use belts. If the brushes are not turning, pull the brush block out, turn the machine on and see if the square hole where the brush block was, is turning. If not then the turbine is bad. Sometimes you can take the turbine apart and clean it out. most times I have found , replace it.
