The air passages through the machine may be plugged, or the impeller (fan) on the motor is slipping on the shaft so that no vacuum is produced. Remove the brush assembly to check the air passage behind it and inspect the brush bearings for collections of thread, string, and hair. Also, inspect the debris collection area for air passage blocking. If there is a filter where the air discharges that might be plugged. Hope some of this helps!

The motor still works but it doesn't collect the dust


did you check all hoses to see if they are clogged? there is a spot at the bottom of the vac where it sucks the dirt/dust into the bag. if there is anything clogged in the hoses it will not allow suction. plus you may want to check the filter if your vac has 1.

Problem sucking up water
Pos Problem sucking up water
Ted by raybrower on Jul 01, 2008
Have a Hoover SteamVac with 5 brushes and it will not suck up any water and I have cleaned all the brushes but it still wont pick up any water

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Part of the problem is with your holding tank, there is a rubber gasket that seals the unit to pup the water and if that gasket is cracked or missing it will not pup. Also there could be something wrong with the suction motor or the Hoover SteamVac may be clogged and will not pup the water, if there is a way to say back track the suction then follow the suction back to the suction motor and if you see a clog – remove it. Otherwise you may have a bad suction motor and it would need replacing as a last resort. If the Hoover SteamVac is less than one year factory warranty it would be covered under the Hoover factory warranty and then feel free to contact the local Hoover Factory Authorized Dealer in your area, so call the cust serv @ Hoover and they can direct you to a dealer that would cover this under warranty. So, 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.

Vaccum has no suction


Here is what we did to fix the problem of our vacuum having no suction.
We unscrewed the three screws on the back and took the hose off of the vacuum.  Then we took the hose outside and put the water hose through the vacuum hose and turned on the water.  After about 30 second the water pushed through a dust bunny the size of a fist and a marker.  Basically, the vacuum did not have suction because the hose was clogged with dust, etc.  After reassembling the vacuum, it worked just fine.

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
Normally if your vacuum has a round belt you may have your belt on backwards, please reverse the belt and the suction will return also you may have a clog in the tube leading up to the bag or dirt cup would be anther reason for the blowing instead of suction. This is not covered under the factory warranty. Feel free to contact your local vacuum dealer for questions.
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.

No suction


Roomba does much of its cleaning by the brush and roller on the bottom, but an important part is the little fan at the back of the debris bin which provides 100% of the 'suction.'
First, take off the vent cover on the back of the debris compartment and start Roomba on a mission. You will see the little turbine spin (if it's working) and probably a little dust cloud will come out.
It may not be working at best efficiency, however, because dirt gets sucked into the housing and blocks much of the air flow. Now that you know what the fan/turbine looks like (it's quite small, only the size of two stacked silver dollars), peer down into the larger opening of the debris bin and view the turbine from the other side. Chances are there's some crud stuck down there which is impeding air flow. (There's a hollow part of the turbine where the air is sucked into before being expelled out the back, that's probably filled with pet hair/dust/etc.) Clean that out using a long knife, chopsticks, or anything else that can reach down in there. Bang the dust bin down (lightly) to dislodge any more hair that's up there and continue cleaning until it's all gone.
I've had 3 Roomba's and they all get hair stuck up there. I only have to do this once a year or so (multi-cat and dog household here!) but it makes all the difference in the world.

Wet dry vac suction not woking


The wet and dry vaccuums should normally have the dust filter removed when used for wet work. If the filter was left in, it will certainly be clogged and useless. I would suggest trying the unit with no filter, just to check there is good suction. If there is, a replacement filter is required. If there is still little or no suction, then it is possible that there is a blockage within the impeller area somewhere. Wet dust/dirt tends to stick really well to the impeller blades, reducing their efficiency to point of almost no suction. I'm not sure if you can get that far into your unit, if you can, it would be worth using a stiff brush to remove and adhered debris.

RC3000 cannot return to the base smoothly


Mine was doing the same thing.  Turned out to be dust that had gathered inside preventing the electric eyes (ir sensors) from work well.  Carefully using some lock ring pliers turn the three grey fasteners 90 degrees counter clockwise.  Then lift off the yellow top cover.  Using an air hose or soft brush clean the sensors sticking up from the circuit board.  Be careful not to bend the out ones has they are not hard mounted.  Then also clean the inside of the IR windows on the yellow top cover.  While your at it take the time to blow out all the dust from the unit.  You should remove the inner screen prior to using compressed air so you can blow out the vac fan itself.  About every six months I do this or when it starts to act weird.  You should blow of all sensors on the base unit also.
