Question about Bissell 7920 ProHeat Pro-Tech Upright Wet/Dry Vacuum

1 Answer

Hmmm Hi there, I actually had tried everything you mentioned except for the vinegar idea which I'll do when I get back up to my home in Oregon. I checked for pinches, the heater, etc. Water does NOT come out of the accessory tool and only will dispense out of the main area for a second or two..any liquid actually starts filling up the area right behind the nozzles and around the pump instead of OUT of the machine. I checked gaskets, made sure there was a tight seal, and even made sure the little valve on the reservoir opens to let cleaning solution out AND made sure the knob on the other section was turned to water and that the spigot/valve on the underneath of that was very well attached. Basically, there are still all of these bubbles and air in all of the tubing...and any water that is going anywhere is going into the machine by the pump instead of out onto the carpet. Any other thoughts?

    I've tried all of these solutions again, and today, I had success! (For about 10 minutes.) Then, after about 5-10 seconds, the flow indicator stops spinning and the solution stops flowing. I notice if I change the solution to "water only", fluid will come up into the flow indicator cap, but it won't spin no matter how tight or loose I tighten the flow indicator cap. Like I said, after taking it all apart again, it DID spin/dispense liquid/soap for a good 10 minutes and then just quit right in mid cleaning. Also, it will "prime" itself if I just turn the cleaner off and back on again. I don't have to remove either of the liquid containers so I know they are seating okay. I replaced the pump months ago when it started not working at all so that's brand new.

Check the nozzles to make sure they aren't clogged. Sometimes there is a problem with the flow indicator cap, maybe too tight or not tight enough. Try squeezing the trigger while turning the can one way or the other. If at a certain point it starts to spray, leave the cap at that point. ( Pump may be bad).

My bissell spot lifter model 1716 won't spray water at all, how do i fix this?

ok - this works even though it probably isn't the "best" solution. Unclog the input and output nozzle ares with a pin. The input area (behind the solution) was my clog problem - I put 2 or 3 drops of CLR into the hole, waited 5 minutes, then primed the trigger. This unclogged it! Fill the tank with a 1:1 ratio of white vinegar and warm water. Insert tank into unit and spray out the contents into the sink. This will eliminate any leftover CLR residue and clean the nozzle thoroughly. For the intake (suction part of the tank) I just rinsed through the lines with the vinegar mix and it seemed to unclog the rest. These things are a pain to take apart and if you break any pieces you'll be stuck - replacement parts have been discontinued for older models.

HOW TO SPOT CLEAN A CARPET I have a "furry family" of a dog and 2...

I have a "furry family" of a dog and 2 cats who I love dearly. Unfortunately, my carpet has suffered from several "accidents" and "upset tummies". It is a challenge to find an effective cleaner that cleans the stain, reduces the odor in the carpet, and is reasonably priced.

In the past, I have tried commercial products that were both expensive and ineffective. I have also used vinegar mixed with water and, although it was effective, it did not achieve the results that I would have liked. So one day, I decided to mix a little scented fabric softener in with the vinegar and water and VOILA what a difference! It removed the stain and left the carpet soft and smelling fresh. It has become my preferred method of dealing with pet stains on the carpet.

If you decide to give this a try, be sure to test this solution on an inconspicuous place on your carpet to be sure it does not discolor or lighten it. So far, I have had only good results from its use.

To Spot Clean a small area:

  1. Fill an empty clean spray bottle with equal parts of water and vinegar. Then add a capful of scented fabric softener to the bottle. Shake it up for 30 seconds.

  2. Spray the stained area

  3. Let it sit for 2 minutes and then spray a little more on it.

  4. Rub the stain with a dry cloth until it disappears.

  5. The vinegar odor will fade as it dries and helps to remove the foul smell

  6. Let it dry and you will notice a nice fresh smell and your carpet will be soft.

  7. Once you vacuum, you will have a hard time telling where the stain was.
I have actually used the mixture above in my Bissell Carpet Cleaning machine with good results. It is much less expensive than commercial carpet cleaning solutions. Be sure to read your machine manual or contact the manufacturer to make sure it does not affect its operation. So far my machine is tolerating it well.

This is a personal tip that I just wanted to share with others. I hope you find it useful.

Steamer has quit steaming. I have not used distilled water (didn't know I was suppose to. It seams to be stopped up.

Any device that actually makes steam should use distilled water. You are boiling away the water to make steam. Everything in the water that is not water will remain in your 'boiler'. So, what to do now ... treat it with vinegar. Vinegar should disolve the minerals left in your boiler.

Thanks for your question @

Hi, I have a older model Sunbeam water cooler that hasn't been used for a while ..Need to know how to clean and sanitize it? got any ideas

Vinegar might help. Run a bunch through the water cooler and it can help clean out the unit (and will give you some disinfection as well) without damaging it. I have used vinegar in my coffee pots with much success over the years. Once you are done, you will want to run a LOT of water through it to get the vinegar taste out of the system, though. If you are not a fan of the idea of vinegar in your water cooler, you can try coffee-pot cleaner ... it is more expensive, but is designed for the same basic use.

You will need to steam the debris out. Place a microwave proof dish half full of water and two tablespoons of white vinegar into the microwave. Heat on high for two minutes. Let this sit for two or three minutes then heat again for thirty seconds. Take a warm damp towel and then try to remove the marshmellow. Don't use a paper towel or sponge. Keep boiling the water/vinegar and rubbing with the damp towel until everything is removed. Its going to take a while but you will eventually get it all.

My Europro shark steam mop won't steam, light on but no steam.

Hard water deposits. I ran some white vinegar through mine, like a coffee maker, and it worked for a while, but clogged again. So I unplugged it, let it cool and turned it over in the bathtub and squirted a small amount of Lime-Away into the hole where the steam comes out. Let it soak for 5- 10 minutes and it is working like is is brand new.

Heating up but not producing steam. Tank may be furred up as limescale deposits in water when tank emptied.

OK. This is an actual guaranteed solution to the Shark "No Steam" problem. The problem is well documented as hard water clogs the steam mops head. And using distilled water should prevent problem (not confirmed). But now that you have the problem, how do you unclog?

First off, Ive had two now. And my solution probably invalidates 1 year warranty, but I'm not interested in going through all the rigamarole of taking my mop back to the store. Maybe yours has expired or you want solution now like me.

This requires a drill. If you've tried the white vinegar route like me and it hasn't worked, and the toothpick, now it's time to get serious.

Remove the four screws. Then slide connection back and remove final two screws. Try blowing thru the small round hole at the end of the connector. If you can't blow through it, the smallest choke point near the hole is your problem.

Using the smallest drill bit in the standard drill set (not sure the size but it fits easily in the hole with room to spare) drill gently into the hole until it breaks thru the first resistance. Now blow through the hole. It should blow through easily now. Run some white vinegar thru to loosen up and remove other hard water deposits if you like.

Replace nozel. Replace two screws, Replace 4 screws. Done.

Use only bottled distilled water from now on would probably be a good idea.

In my opinion the problem is a design flaw built in by the Shark people. Appropriate name. Its called planned obsolescence. :( It breaks, you buy a new mop head (or entire mop if you can't find their part's website.)

Hi Bobbie Take apart the electro floor head if you can and inspect inside - it may well be that there's clogged dust preventing the brush from turning and also check both sides of the actual beater bar as thread and tangled hair can often lead to a brush turning every so often.
