Trouble with vacuum suction

I have a Thermax AF vacuum/steam cleaner. I purchased it in 1994. The problem is, when I put the recovery tank in the machine and then put the dome lid on and turn on the vacuum switch there isn't any suction. Normally if you put your hand on the hole in the center of the dome lid you can feel immediate and powerful suction. The hole in the dome lid is where the flexible hose is attached to the unit. If I take out the recovery tank and turn the machine on I can feel the suction through the hole in the bottom where the recovery tank sits. I'm not sure what the actual problem is. The recovery tank seats properly when I put it in and turn it until it drops/locks into place. The dome lid also has both rubber gasket seals so I know that isn't the problem. I did recently have to have the cord replaced. Could the repair person have done something to affect the vaccums suction? Any help would be greatly appreciated. Thanks, Kelli

Why will my hoover spin scrub steam vac upholstery attachment not suction?

With this model, check all hose connections and recovery tank lid. if you have good suction before you put on the tool it may be the tool that needs service. inspect the tube under the recovery tank for the round gasket and the filter inside the tank.

Won't pick up brown water

Hello! Follow these quick trouble-shooting steps to restore suction to your Hoover F5835900.

1. Remove the clean water tank.

2. Recline the handle and let the cleaner lay flat.

3. Remove the dirty water tank lid.

4. Reposition the front panel located on the outside of the tank in the center. It should be flush to the tank, even straight across and pushed down as far as it will go.

5. Assemble the dirty water tank lid back on from the front to the back. The lid should not lift up from the front.

Try it out. The cleaner should now have suction. Good luck!

My steam vac doesn't seem to have suction. Help?

(1) Make sure tank lid is sealed to the tank.
(2) Is the filler panel in place on the front of the recovery tank? (Square shaped plastic panel)
(3) Is the tank gasket in place under the hood? There must be a rubber gasket on the round pipe that the recovery tank seals to when it sets down in to the cleaner foot. This connects the vacuum path to the tank.

I would almost guarantee the recovery tank is not seated properly. Trust me, I reseated the tank 5-10 times before giving up. I finally decided to give it one more try before forking out the money for another cleaner. I removed the clean water tank, turned the machine on (you could feel the air blowing out the sides on the bottom). With the machine still running, I unclipped the recovery tank and lifted it up (yes, you can do this, and it creates a very loud air thrust, but don't be scared), then I SLAMMED it back down into the seat and immediately I could tell the difference. The air stopped blowing from underneath and I could tell I had suction once again. I turned it off, put the clean water tank back on, and it worked like a charm. Trust me, you may be convinced that the recovery tank is seated ain't! Hope this helps!

Lost suction, gasket problem

This is a great basic steam cleaner. I have not heard of repeated problems of this type. The gasket is called a standpipe gasket. I would try to use a non-permanent sealant such as RTV silicone to adhear the gasket, eventually if this needed service you will want the gasket to be able to be removed.

The recovery tank also has a clear plastic piece in the front that is suppose to be snapped into place to make sure its in place pull on it in the direction of the handle of the steam cleaner if it snaps then that was the problem it got out of place
