Troubleshooting A Robot Mop That Isn’t Spraying Water

If you’re having trouble getting your iRobot mop to spray water, then you come to the right place.

In this post, we will outline some of the most common causes for this issue and provide solutions to fix them. We’ll also cover why a certain hose gets clogged and what you need to do to keep your Braava robot mop or other robot mops from getting clogged and not spraying.

Not Spraying Water – Do This!

The most common reason for a Braava robot mop not spraying water is that the water tank is empty or not seated correctly. Make sure to check both of these things before assuming something else is wrong. You’ll be amazed how common the tank was empty or not seating right that I see.

If the water tank is empty, simply refill it and reseat it according to the instructions in your manual. If it’s not seated correctly, this can also be the reason why water isn’t coming out. Make sure the tank is snapped in all the way and that there are no leaks.

Another common reason for a Braava not spraying water is because the sprayer nozzle is clogged. The easiest way to clean it is to remove the water tank and use a paperclip or something similar to clear any debris that might be blocking the nozzle.

You should also check the water filter to see if it needs to be cleaned or replaced. A clogged water filter can also cause your Braava not to spray water. You should be cleaning your water jet filter at least every month, if not sooner, if you do a lot of cleaning.

Here is a video on how to clean the jet filter:

There are often more filters, located near the tank, that you need to removed and cleaned. A toothbrush may be needed on the fine filters to get them unclogged. If you notice dripping or dribbling instead of spraying, this extra fine filter could be your issue.

Check Cleaning Settings

Some robot mops have an option to wet and dry-clean your floors. So make sure you have the correct setting in your robot mop app.

You can even set a no-mop zone for many of the robot mops, so make sure your home is not set as a no-mop zone. Please ensure you’re not starting the robot mop on carpet or a rug, as this can confuse its sensors as they try to avoid such things.

Don’t forget, you can adjust the water level that your robot mop will use, so make sure it’s not too low. Try cleaning with the highest settings first to see if that helps.

Use The Correct Mop Heads

Don’t forget to have the correct mop, many robot mops can determine what type of mop you have installed and will not release water if it’s a dry mop head.

I suggest going with reusable wet mop heads for your robot mop. The one-time use ones are not that great and just a pain to use.

Check Water Float

A float is used to determine how much water the robot mop has, and if this float is damaged or stuck it can read wrong and the robot mop may not release water.

Locate the float and make sure it can move up and down.

You may have some robot mops that use two electrical probes to measure the water level, so make sure those are not corroded or damaged, they should be two shinny metal probes or plates.

Braava Still Not Spraying Water

If you tried everything else and your Braava robot mop is still not spraying water, then it’s probably the pump or the hoses at the pump.

If you use a floor cleaner that is not recommended, you run the risk of clogging the small tubes the robot mop uses. The wrong cleaner can basically glue a tube shut and stop the water from flowing though it.

To solve this problem will require some basic tools, but it’s not hard to do. Follow along in this video to unclog the pump on your Braava robot mop.

Best Floor Cleaners

The best floor cleaner for your robot mop is plain and clean water.

The best type of water is bottle or distilled water, as covered here.

Some models, like the Braava, have special floor cleaners you can use. But if you’re ever in doubt, use plain and clean water.

Hard Water & Robot Mop

Hard water, or well water, is not the best for robot mops.

Robot mops use small hoses and don’t have a lot of suction, so small debris in water can get them clogged. Hard water also has more minerals that can corrode certain metals and make your robot mop not work as well.

Try to stick to distilled or bottle water when it comes to your robot mop.
