Funny, lots of Hoover steamvacs seem to have this exact problem. I just fixed mine today and it was a problem with the turbine that spins the brushes. It took me a while to get to the part without breaking the plastic housing. If you have the patience, you should have no problem figuring it out. When I got to the turbine part, I opened it up and found that the metal disc at the end of the shaft was rusted and that no grease was ever applied. I took a metal brush, cleaned it up, greased the wheel, and then closed it back up. After putting it back together, it worked great. It almost looks like they don't grease this part on purpose so that it rusts and fails in order for you to spend more (buy parts, extended warranty, etc.). There's tons of grease on one of the other wheels that doesn't even need it. The product works great other than this. I've had mine for about 1 and 1/2 years and this is the first problem I've had with it.

Re: brushes won't spin
Open unit's bottem cover and look for the following:
- Motor works
- Belt which transfer motor's movment to the brushes, in place and not broken (most frequent phenomenon).
- No mess on brushes axis which prevent their free movement.
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.
- Provide details, support with references or personal experience.

Usually when the brushes won't turn it is due to a bad turbine. Insert a screwdriver into the square hole that the pin on the brush fits into, and see if it turns. If it is seized up, the turbine assembly will need to be replaced.
There is no belt on the Hoover SpinScrub. The brushes are turned by an air driven turbine. To test the turbine, insert a flat screwdriver into the square hole that the pin on the brush assembly normally fits into, and see if the fitting turns. If it doesn't turn, the turbine has seized up and will need to be replaced.
The brush system on this model has a poor engineering design in that the brushes are running off an air turbine, which uses a steel bushing to spin the turbine which gets rusty from the moisture when the machine is being used. No long term solver. I would replace the machine with a Dirt Devil Platinum Force model
The brushes are turning by an air driven turbine. The turbine has a
pivot bushing made of steel inside of it that gets rusty because of the
water that is running through it. The turbine gear will have to be
You can access the turbine gear by removing the hood. You can find a
genuine hoover replacement part by following the link
below. Just find the model number of your Steamvac.
If the speed control switch on the hood is in the On position, it would appear the drive mechanism for the brushes is not spinning internally. The drive mechanism could easily be replaced by a technician.
for the spin brushes it is most likely the motor is fried if you smell something burning it could be jammed or the wires have be shaken off the motor terminals. for it not turning off you need a new switch.
SAME PROBLEM Hoover F7452 900 brushes won't spin; cleaned and move freely, under filter slid out and cleaned, still froze up....had it a little more than a year so probably no warranty.....assuming turbine related and will take it to dealer......how common is this problem with this model???
