Re: hoover steam vac model 7210-900
Did you clean both filters? There is one on the tank and the other is from the bottom, it ha a red frame, pull it out to clean. Pull the brush block out, is the shaft that goes up into the machine broken off? If so replace the brush block. While it is out, trn the machine on and see if the square hole up where the brush block goes, is turning. If not then the turbine has gone bad. You can sometimes clean the turbine out, otherwise replacing it may be the best option.

The brushes turn by the airflow from the vacuum suction turning a turbine motor to spin the brushes. First try to spin the brushes by hand. If they won't turn it usually means the brushes are clogged with hair and debris or need replaced or the turbine could be seized up. If the brushes won't spin reach under the brushes and push the little tabs and remove the brush block asssembly from the machine. If the brushes spin freely after you remove them from the machine then that means that most likely the turbine is seized and will need to be repaced. If the turbine is not seized you may simply just have a clogged filter screen. Most steam vacs have a red screen filter either on top or underneath the machine. On the top it is under a little clear plastic cover that you have to pry off before you can pull the screen out to clean it. If it's underneath you can pull it out and clean it.
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 not spinning is most likely is caused by seized bearings in the turbine, requiring shop service (easy fix). The suction issue can be caused by the standpipe seal missing or lower recovery tank not on properly, on some models missing front panel. I would need more exact model info to assist further.
The brushes are all connected to a single shaft. This square shaft is connected to 2 sets of gears and then another shaft which is turned by an impeller (suction from the vaccum pump is used to turn the impell and thus the brushes). There are 2 bearings that the impeller shaft turns on. It's likely these are rusted up and just need a bit of WD 40. Took me 30 min to take apart, lube, and put back together. Remember, its plastic. If things won't come apart, look for another screw. Mine was a brand new unit and the top bearing was rusted.
Take out the brush block, make sure that the shaft is ok, it goes up into the turbine, which is what drives the brushes. If the shaft is ok, then the turbine either needs to be cleaned and lubed, or replaced.

This also happened to my own Hoover Steam Vac and there was a broken part that connected to the brush assm that I had to replace, it has been a while but once they replaced the part everything worked just fine and it was not that expensive and I am still using the vacuum still to date and it is working just fine. I believe it was something like the switch for the brushes on/off switch or the part was part of the handle assm. Check you owner’s manual for the exploded view on the vacuum or also check with your local vac dealer. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions. http://www.hoover.comTelephone Contact our Customer Service Department at 1.330.499.9499 Monday through Friday 8 a.m. - 7 p.m. EST Don – The Vac Man Go Ahead.Use Us.
