    I have the same problem! The green light flashes only shortly when first turned on.

    I have a similar problem...my red light indicator stays on and the green never comes on. I installed a new bag. Washed and dried the intake filters, checked for any blockage in air flow tubes. My suction is strong but my green light never comes on...the red light stays on constantly. When the unit was new the green light would come on and flicker...is it possible that the green light bulb is defective/burned out?

    The green light came on and operated as it was supposed to for the first hour of use, but after that, the red light is on constantly!

You either have a problem with the sensor or the circuit board. Most times it is with the sensor. Take the hose off, look inside of the part that the hose hooks to, you will see a disc, it may be clogged with dirt, try cleaning it, if that doesn't work, then the sensor may be bad.

Velocity red light on


Hi! If the full indicator doesn't turn off, this may be an indication of dirty filters or a possible clog.

The vacuum is not rolling easily. It "drags" on the rug.


Hi There,

When a Hoover Windtunnel becomes hard to push, this usually indicates that self-propelled has stopped working.

When this stops working, it can be caused by several things. The first, most common problem is that the belts have either broken, or stretched to a point where they no longer engage the self-propelled mechanism. In order to verify this, simply make sure that the machine is set to the Carpet setting, turn the machine on, and turn it over on it's side with the handle release pedal reclined (make sure it's not in the upright position). Is the brush at the bottom of the vacuum spinning? If no, this definitely indicates that your belts have gone bad and need to be replaced. There are two belts on your machine, one controls the brush, the other controls the self-propelled mechanism. We've shot a helpful video that walks you through step by step on how to replace the belts.

This is by far the most common problem that we see on your particular model:


The other problem if the belts are installed properly that would cause the self-propelled wouldn't work would be the self-propelled actuator arm. There is a cable that starts at the handle of the vacuum, and runs all the way down to the floor head of the vacuum that controls the transmission. As you pull backwards on the handle of the vacuum, the cable pulls this actuator arm backwards, which then turns the wheels backwards, and when you push forward it turns the wheels forward.

The problem with the way it's designed however, is that if you pick up the vacuum cleaner by the handle of the machine rather then using the carrying handle on the back of the vacuum, it causes too much tension on the actuator arm, and will cause the cable to rip right out of the arm.

This is a VERY common problem on this model. To check and see if this part is broken on your vacuum, step on the handle release pedal so that the handle is in the vacuuming position, push the pedal a second time so the machine lays flat on the floor.

Now if you look right behind the height adjustment switch, and the rug / floor switch where the floor part meets the upright part, you should see a cable that connects into the actuator arm. Pull up and down on the handle and look for movement. Is the cable loose with only a nut attached to it, or is it resting in the actuator arm?

Here's a very helpful link that shows you exactly how to replace the actuator arm:

Leaving bigger dirtier wet spots after cleaning


Sounds like the vacuum motor is defective or you have a clog in the vaccum line. Basically everything is running except the vacuum "Suction" cycle. Do you hear the "Suction" phase (light indicator) during operation when it loudens like a whine? That would be the vacuum phase. Is the dirty water reservoir clean, do you rinse it thoroughly when you empty it? Have you removed the hose assy and rinsed it out? I think it is still part of the auto cycle even if you don't use the manual tool.

Hoover vacuum cleaner indicators stuck


the sensor is located in the tube that the bag mounts to, if you take the bag off of the unit and have an air compressor handy you can blow out the port hole this should dislodge the particulates that are causing the false reading, there is defintely a clog in the system. let me know if this helps thanks Don the Vacuum Doctor Alb, N.M.

Bissell Rug Cleaner Model 1695


I think you have the same problem as me, If you lay the handle down and remove the tank you'll see a vacuum hose that runs from about the middle of the machine back towards and up into the handle. that hose probably has a hole in it. which is my problem also I can't get at the part of the hose that runs into the handle. I hope I could at least help you figure out what the problem was.

Beater bar works intermittently


When you push the hose into the tube, there is an acuator that will push the switch so the beater bar will turn. That switch could be just dirty, dust gets in them and they won't always work, the acuator may need to be replaced. Either that or you have a bad wire connection somewhere in the noozle or where the wires just go into the noozle asm.
