Vax Dual V spin scrub brushes do not rotate any more

SOURCE: Spin Scrub Brushes won't turn

If the brushes quit spinning, either the brush block shaft that goes into the turbine broke off, or the turbine is bad. This unit is tricky to take apart and then put back together again. But pull the brush asm off, then start taking out screws. But if after you pull off the brush block, look up where you will see a small square hole, turn unit on and if not turning, usually the turbine is the cause and will have to be replaced.

If this is a Hoover Steam vac, the turbine which drives the brushes is bad. If not a Hoover, then what is it, they are different, need brand and model number.

The problem I found with one a neighbor was tossing out is the bearings in the part that drives the brushes were stuck. Lubing them up solved the problem, but took a bit of work to get into. This also provides a good chance to clean the crud out of bits that usually don't get much attention. I found mine clogged with a fair amount of pet hair.


You'll need a Phillips & Flat Screwdriver, some light machine (3-in-1) oil or Lithium (white) grease, and a lot of patience. Having a pan or something handy to keep all the little bits organized would help.


First remove both the soap & recovery tanks, they'll just get in the way & are designed to be easily removed & replaced for filing/dumping. Be sure to fold the "wings" for the recovery tank in or they'll foul removing the cover later (as will the brush speed button).

The tricky part is getting the Brush Speed knob off. It's held on only by friction, but can be tough to pull for without breaking the plastic stick it's pushed onto.


Remove the brushes. There are 4 blocks between the outer & next in rollers. Put the flat screwdriver between the gray & clear plastic, pushing gently toward the brushes. This pushes a wedge away far enough from a hole in the gray plastic to "unhook" the brush housing from the main body. Once all 4 are clear, the brush assembly should pull out easily.

Remove the 2 big screws in front of the brushes and the one at the back of the clear plastic front of the vacuum bit. The small ones at the extreme front corners hold on the clear plastic front, and can be removed if you want to clean out the vacuum channel, but are not necessary to remove to remove the top.

Toward the back sides of the top are 2 slots that hold this part on. Once the front screws are removed & the front is loose, push the side in gently & you should be able to lift the back of the cover. Push in lift both side, the top should pop right off.

Now I have the top off, holding 2 black & 1 silver long screw. In the center-front of the new-exposed guts is a box with a round top & a cone at the front with 2 screws.

This is the Brush Motor Assembly, and it's actually vacuum-powered. Remove the 2 screws holding down the from, then look for 2 large holes on the bottom of the unit behind the black "squirter bar".

There's very long screws at the bottom of these holes that also hold down the brush motor.Once the 2 bottoms screws have been fully loosened & the top-front screws removed, the brush motor should pull up easily.

On the right is a square port, in front the the brush speed stick (where the gray button pops onto). on the left is a gray & black hose, these should pull off easily, but may have some liquid in them.

Pull out the brush motor & set it on a convenient spill-resistant work surface upside-down. You should see the square-hole drice for the brushes, a gray piece of plastic, & a cresent-shaped hole.

The port at the front & hole on bottom provide an air path for the vacuum to poll air through this assembly & spin the brushes. You should see 2 screws at the back of the motor & 2 more at the bottom of holes surrounded by the gray plastic. Remove all 4 screws.

You can now pull off the bottom cover with the gray plastic. Front to back you should see the brush drive gear, an intermidiate gear, ant one of the bearings for the fan that drives the whole thing. pulling out the bearing & gears to clean out this area & lube up the gears with some Lithium Grease helps, as well as making sure the bearing is well lubed with 3-in-1 oil and/or lithium grease.

The top is held on at this point with 4 platic clips. The top doesn't need to be removed unless you *really* have to see the fan. The clips can be broken off if one is not careful, and there's nothing in there to be lubed. Best to leave it as-is.

At the top of the driveshaft is a second sealed bearing. I couldn't figure out how to get it out without braking it, lube this one in place. The bearings are supposed to be sealed, so removing the black "washer" from the bearing is done completely at your own risk. I just put some oil on there, spun it to work it in, then repeated with the white grease.

Replace the intermediate gear, the brush drive gear, then the lower sealed bearing in that order. You can spin the gears to ensure they're spinning well. Mine was OK, but after a bit of use worked the grease in & the brushes really started spinning.

Keep in mind everything here except the screws is plastic, be creful to get a snug fit with the screws without overtightening. "Gorilla-ing" the screws will just break the plastic & make the whole adventure an exercise in frustration.

Reattach the bottom plate with all 4 screws, 2 in the holes in the gray plastic, 2 in the back.

Reattach the gray & balck hoses to the left side of the brush drive. They're 2 different sizes, so there's only 1 place the smaller hose will fit easily. Place the assembly back in the machine & replace the 2 screws in the front.

Flip the machine up so you can put the 2 really long screws back into the underside of the brush drive. There's 2 guide slots on either side, make sure the brush with the indicator wheel on top goes into the big hole on the right. You may need to spin the brushes a bit to get the center squure stick to line up with the hole in the drive gear. The brushes should pop back in easily if everything's lined up right.


Put the top cover on, making sure the Brush Speed stick & center screwhole line up, as well as the back sides snap into place.

Screw down the top, then flip the unit up so you can snap the bottom-front of the top over the gray wedges on the front, then screw into place.

Replace the Recovery Tank, fill & replace the solution tank, and test-drive.

Greetings from GoVacuum,

The Hoover SteamVac's are notorious for this exact problem. There are several things that can be causing this probelm.

First, what you'll need to do is take the brush block out of the machine. To do this there are 4 clips on the brush block. You will need to turn the machine upside down, and pull down on the brush block to where it won't pull out any farther. There are 4 clips, 2 on top, and 2 on the rear of the brushes. (See picture I have circled one of the clips in red). Simply press these clips at the same time, and pull the brush block out of the machine. I'd say that 60% of the time that I see this problem, the main issue is that the brushes just need to be cleaned. If you have pets in the home, a lot of the time the pet hair will just be lodged inside the brushes, will prevent them from spinning. Use a pressurized water hose with spray nozzle is ideal) and spray each brush with water to dislodge any pet hair. You should be able to get these brushes spinning when you spray them. Spray each brush until the brushes are spinning pretty fast. Re-insert the brushes into the machine, and test to see if the cleaning has fixed your problem. If the cleaning still fails to fix the problem, take the brushes back out of the machine.

One you have the brushes out of the machine, the first thing you should look at the brush stem that goes into the turbine inside the machine. This is the green pole pictured in middle of the brush block. Examine this pole to determine if the top of it has broken off. It should exactly how the picture shows it. Make sure that the plastic has not broken.

If the pole has broken, you will simply need to replace the brush block. If the pole is not damaged, the next thing to try is to turn the machine on while you have the brushes out. Look inside the machine, where the pole goes into the turbine (also important, make sure the switch for the brushes is turned to "Rotating Brush Speed Hi), this female receptacle should spin when the machine is turned on. It is important the try this when the foot pedal is released, and the handle down, and not in the upright position, as there is an internal switch that shuts the brushes off when the machine is in the upright position.

If you notice that the female receptacle where the brush pole is inserted is spinning, then your turbine is fine. If this part is not spinning, then most likely you will need to replace your turbine.

I hope this helps you with your problem. If not, please feel free to request a repair clarification and I'd be happy to walk you through the diagnosing. I also can provide you with a blown up parts schematic to your machine, please just get the model number off the back of the machine and provide, and provide me with the full model number. I would be happy to provide any technical support you need, just request a clarification on the repair.

Make sure that the plastic pole has not broken.

If the pole is broken, you will simply need to replace the brush block assembly. The model F5914-900 uses Hoover 5 Brush SpinScrub Brush Block Part # 48437022.

If the pole is not damaged, the next thing to try is to turn the machine on while you have the brushes out. Step on the handle release pedal so the SteamVac handle is lowered, and not in the upright position, as there is an internal switch that turns the brushes off when the machine is in the upright position. Now look inside the machine where the pole goes in. There is a green, square shaped female receptacle. This is actually the internal turbine that spins the brush block. Make sure that the switch for the brushes on the top of the machine is turned to "Rotating Brush Speed Hi". Turn the machine on.

If you saw the female receptacle where the brush pole is inserted was spinning, then your turbine is fine. If this part is not spinning, then you will need to replace your turbine.

I hope this helps you with your problem. Please feel free request a clarification request form here on Fixya if you have any questions, I'm always happy to answer follow up questions you might have.
