Why Does Your Bissell Carpet Cleaner Leave Dirty Water?

When you clean your carpet, you expect all the stains to be gone and the fibers to be soft and smelling fresh. But when your carpet cleaner leaves dirty water, something is wrong. You might not be cleaning your carpet the right way, among other reasons.

Below are some reasons why your carpet cleaner may leave dirty water, even after cleaning it:

Cleaning Too Fast

You can’t hurriedly clean your carpet and expect it to be thoroughly clean. If you do, you may not achieve the results you desire. 

When you are washing your carpet with a machine, it is paramount that you move it slowly. That way, you’ll give it time to dispense the shampoo solution at a suitable rate, covering every inch of your carpet. So when the shampoo is rinsed and sucked out, there should be no dirty spots remaining. 

That means when your machine rinses the carpet and sucks out the shampoo, the water should be clear. You probably need to do this several times for the water to be clear. Note that if you are using a small carpet cleaner, it will take you longer to clean. 

Too Much Foam

Check out this carpet shampoo on Amazon.

If you mix too much shampoo with water in your carpet cleaner, you’ll leave a lot of foam as you clean. Thus, your carpet cleaner will not suck up all the foam. The foam that’s left on the carpet will attract dirt. 

To avoid this situation, follow the directions provided by the manufacturer. It will help you mix the correct quantities of the shampoo solution. 

Missing Some Sections On The Carpet

You can find this Bissell carpet cleaner on Amazon. 

It’s easy to miss some parts of your carpet while cleaning it with a machine. If you miss some sections, those parts of your carpet may look dirty. This means the moisture left after rinsing may still look dirty. 

The best way to avoid missing a spot is to move your carpet cleaner in straight lines. Press the trigger on the carpet cleaner to release water and then push it forward. Release the trigger, and move it backward on the same line. When you finish one line, move over to the next line. As you do so, make sure you overlap slightly on the lines. 

Mold Infestation

If your carpet does not dry well after cleaning it, mold can form in it. If not attended to quickly, the mold can penetrate deep into the carpet. 

Dirt Too Deep In Carpet

A carpet can be very dirty, even though it appears clean. Therefore, the water may still be dirty if you don’t rinse the carpet enough times. That’s why you should rinse it until the water is clear.

To prevent your carpet from being too dirty, no one should walk on it with the shoes worn outside. On top of that, vacuuming often helps minimize dirt on your carpet.
