Steam Vac model: F7425-900

HI, it's Jim from Crucial Vacuum!

If your vacuum is experiencing difficulties with suction there are several places you can check to help your vacuum operate at its peak performance.

Check out your brush roll. Look for any noticeable debris, and be sure to manually rotate the brush roll to unearth any hidden clogs that may be behind your brush roll. If you see carpet fibers, or strands of hair remove these with a razor, or scissor.

How do the bristles look on the brush roll? If they're loose, or look worn down then it may be time to replace the brush entirely.

Is the belt intact? After usage the belt will stretch out and lessen the tension on the brush roll. This could be causing the brush roll to have a lack of resistance against it. You want to be sure the belt is on there nice and tight. If your brush roll isn't operating properly it won't be able to pick up dirt and debris.

Be sure to empty your unit's dust cup. Allowing for fine dust and debris to rest in your unit's dust cup for a long period may cause your unit to become clogged, which leads to poor or even no suction for your vacuum.

It is recommended to wash and clean your unit's filter weekly. To do so, empty your filter screen outdoors to take off any excess debris and then clean under running water until the water comes out clean. Allow the filter screen to fully dry before inserting it back into the unit. This may take up to several hours.

If you have suction as you say, the tool is faulty.
They come apart so you can clean them. remove all hair and debris from the roller brush (use a coin to split it using a quarter turn on the two/three screws). Try turning the brush with your fingers. If it is stiff, it needs attention to the bearings in the tool probably. If it turns OK, then the mini turbine inside is faulty -- replace the tool.

clean bearings on rotator possibly ruined motor

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.

(1) Assure the Brush Control on the hood is NOT set to the OFF position.
(2) Remove the brush assembly by pulling/unlatching it from base on each side.
(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
(4) Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen and reassemble.

Can you rotate the brushes manually (grab some of the yellow bristles and rotate the brushes). If they are not jammed, then your air fan drive is clogged or broken. Air must pass through the fan to spin the brushes... so confirm air flow by powering the machine on and feeling for decent air flow. Clear any obstructions that my restrict air flow....

There are no belts on the SteamVac series. If you have a brush rotation problem, please check this:
(1) Assure the Brush Control on the hood is NOT set to the OFF position.
(2) Remove the brush assembly by pulling/unlatching it from base on each side.
(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
(4)Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen

Please check two things:
(1) The shutoff switch on the hood is NOT set to OFF for brush speed.
(2) Remove the red filter panel from under the cleaner, behind the brushes, and clean the hair/debris from the screen filter. Squeeze the two panels together, and pull down to remove from the pocket.

I Had the same problem, The brushes are operated by water pressure. Under the machine were the brushes are is a white peice of plastic pull this out and try cleaning the screen. I found this when I removed the cover and lubricated the gears at the brushes, If that does nto work you will have to remove the turbines and lubricate.

The filter for the U5753 does not rotate on it's own. There is a knob on the lid of the dirt canister to rotate before you empty the container, but it does not rotate automatically. If the filter is getting dirty quickly, it could be a result of very fine dirt going through the pre-filter screen and blocking the filter. You should also check the filter UNDER the dirt container for blockage and also the exhaust filter on the side. These are both washable and must be bone dry before re-installing
The main filter cartridge is a long cylindrical style and is coated with a teflon material so that all you should have to do is tap the filter lightly to dislodge any dirt. You can wash the filter by running warm water over it and using a SOFT brush to clean the surface. This filter must be BONE DRY..... before re-installing.
By the way, the lifetime filter is not lifetime. It should be replaced every two years, under normal use.
