- The Braava Jet 240 is small enough to maneuver itself around obstacles in your home without damaging them.
- Fairly inexpensive as far as robot mops go
- This Braava robot mop needs a new cleaning pad fairly often, which means more maintenance.
- The 240 struggles with mopping up thicker, stickier substances.
The Bottom Line
The Braava Jet 240 mopping robot is great for light and maintaining cleans. However, the relative size and power mean it has more trouble with sizable messes. It won’t be a replacement to your traditional mop, but it could be a nice addition to help keep floors sparkling between deeper cleans.
The design of the Braava Jet 240 is simple, but sophisticated. There is only one button on the top of the unit and a small handle that lifts up for direct access to the water reservoir and cleaning pad release.
BATTERY | As you move down the side of the unit, there is a battery slot where the battery can be inserted and removed for charging.
SPRAYER | On the other side of the Braava Jet 240 is the sprayer. This is a small hole that projects water in front of the unit when it is being used as a mop.
CLEANING PADS | The cleaning pad holder and wheels can be found on the bottom. The cleaning pads can be slid into the slot found on the underside of the unit. The wheels work to drive the unit and can turn easily, helping to add to the maneuverability of this Braava robot mop.
STYLE | With regard to colors, the Braava Jet 240 contains an all white color scheme with a few hints of blue. From an aesthetic standpoint, I have no complaints about the Braava Jet 240.
How Braava Jet 240 Cleans
The Braava Jet 240 utilizes three different cleaning styles; wet mop, damp mop, and dry sweep. Bear in mind, the user does not select the cleaning mode on this Braava robot mop. Once a cleaning pad is inserted, the mop will recognize the pad automatically and place itself in the correct cleaning mode.
- Wet mop – When in wet mop mode, the Braava Jet 240 uses a triple pass cleaning motion, precision jet spray, and a water activated cleaning agent to help mop up the dirt and grime. Once the water has loosened the dirt or grime, the mop passes over the mess three times and uses a vibrating head to lift the remaining mess.
- Damp mop – In damp mop mode, the Braava Jet 240 drops down to two passes over the mess, a reduced amount of spray, and the same water activated cleaning agent to mop up the dirt or grime.
- Dry sweep – When used in dry sweep mode, a dry cleaning pad works to lift dust, dirt, and pet hair with a single pass.
All three of these cleaning modes use the same navigation software, as the iRobot Braava Jet 240 houses several sensors on the perimeter of the unit to help it mop and sweep in a more efficient manner. In other words, this Braava robot mop will not go back over the same area after it has attempted to clean it already.
Size & Dimensions
The Braava Jet 240 is quite small, coming in at 6.7″ wide, 7″ long, and 3.3″ tall. This robot mop also weighs 2.7 pounds.
- Length – 7″
- Width – 6.7″
- Height – 3.3″
- Weight – 2.7 pounds
The Braava Jet 240 is one of the less expensive mopping robots from iRobot, but it does include a few extra parts and accessories:
Battery: The battery included with the Braava Jet 240 is a separate item that has to be removed from the main unit to be charged. This battery is an 1,800 mAh, lithium-ion battery that needs 2 hours to charge fully.
Battery Charger: A battery charger is also included. This charger plugs directly into the wall and holds the battery while charging.
Dry sweeping pad: Two dry sweep cleaning pads are included with the Braava Jet 240. These can be inserted onto the bottom of the unit and the mop will automatically place itself in dry sweep cleaning mode. These pads are best suited for dirt, dust, and hair.
Damp sweeping pad: Two damp cleaning pads also come with this Braava Jet robot mop. Once again, these can be slid into the respective slot on the bottom of the mop and it will place itself in damp mop cleaning mode. This pad is best suited for dirt and dust.
Wet mopping pad: Two wet mopping pads are included and can be used to mop your floors. These pads are best used when lifting dirt and stains.
Although there are not a ton of extra parts and accessories included with the Braava Jet 240 robot mop, the items iRobot includes are more than enough to get you started.
You will need to order more cleaning pads as you continue to use the mop, but there are lots of options available. These washable pads on Amazon are a great value, in our opinion.
The following tests are designed to show how the Braava Jet 240 performs as both a mop and a sweeper.
We tested the Braava Jet 240 as a mop on tile flooring, spreading three different debris types across the floor and allowing the robot mop to clean the floor until it thought the job was complete.
Next, we tested the Braava Jet 240 as a sweeper, allowing it to run on a dusty hardwood floor for 30 minutes. After doing so, we took a look at the floors and made our assessment of the Braava 240’s cleaning performance.
- Dirt & Mud 95%
- Honey 85%
- Soda 70%
- Sweeping 93%
For starters, the mop test contains three debris types:
- Dirt / mud
Each of these debris types offer a different level of stickiness and consistency, allowing us to test the Braava Jet 240 robot mop against a light, heavy, and liquid substance. All three debris types are spread across our testing lane in three separate sections.
Throughout our mopping tests, we try to give real life examples and be as consistent and fair as possible. The mopping test procedure goes as follows:
- Measure out 3 oz of soda and spread the soda across the back of the testing lane.
- Squirt honey in the middle of the testing lane, covering a majority of the width of the lane.
- Create a muddy substance from dirt and water then spread the mud with a shoe.
- Make a pass across the testing lane and compare the amount of each debris type mopped up on pass one to the untouched debris.
- Make pass number two across the lane and analyze the amount of each debris type mopped up.
- Make a third pass, if necessary.
The Braava Jet 240 did reasonably well on our mopping tests, but there were a couple of problems that came up during testing. We ended up running two separate tests with this mop, one with soda and one without. Both the honey and mud were present for each test.
SODA CLEANING | The first test that included soda was almost a complete failure. The soda was simply too much for the 240 to handle, as it did its best to soak up the soda, but could not get it all. Once the wet cleaning pad reached its capacity of soda soaked up, it began pushing the remaining soda around our testing lane.
MUD & HONEY CLEANING | During this same test, the mud and honey were less of an issue. The Braava Jet 240 made a few passes over the mud and had no problem mopping it up. As it moved to honey, the process was not as easy. However, tt was eventually able to remove a majority of the honey before moving onto the soda.
After removing the soda from the testing lane and testing the Braava Jet 240 against just the mud and honey, we saw a different result.
Once again, the mud was not much of an issue. The 240 worked its magic and quickly cleaned up the mud. On the other hand, the honey became more of a problem this time around. The Braava Jet 240 robot mop made passes back and forth across the honey while spraying water in front of the unit to use as a cleaning solution. The water did help to loosen the honey, but it was not a total solution.
As the iRobot Braava Jet 240 continued to work on the honey, it would stop and use a vibrating cleaning head technique to agitate more of the honey, which also helped in the long run.
All things considered, the Braava Jet 240 performed well, but did show signs of struggle with the honey and soda. Messes that involve a large quantity of ultra sticky substances or liquids will need a stronger mop or floor cleaner (see our Bissell Crosswave review). The relative size of the cleaning pad may also have played a role.
The larger cleaning pad on the iRobot Braava 380t (in addition to other superior features) allowed it to pass our cleaning tests more easily.
The sweeping tests were much more of a positive on the Braava Jet 240. After letting the robot drive around a hardwood floor with heavy foot traffic for ~30 minutes, we found a good degree of dirt and dust on the dry sweep cleaning pad.
Additionally, the Braava Jet 240 covered a good amount of ground during those 30 minutes. Overall sweeping performance was fairly good.

Braava Jet 240 vs. 380t
So what are the differences?
CLEANING PERFORMANCE | Most notably, cleaning performance. During our cleaning tests the Braava 380t created strong cleaning performance across all of our tests. Dirt, mud, honey, and our sweeping tests were virtually flawless.
|Braava Jet 240||Braava 380t|
|Dimensions||6.7″ x 7″ x 3.3″||9.6″ x 8.5″ x 3.1"|
|Warranty||1 year||1 year|

The Braava Jet 240’s issues with soda were more to do with a lack of absorption (due to the size). It’s cleaning issues on other debris types can at least be partially attributed to the size and relative pressures applied.
NAVIGATION | Navigation on the Braava 380t is better than the Braava Jet 240. The 380t uses their Northstar navigation cube, which helps orient the robot mop. Not to say the 240 is bad, but compared to the 380t, it seemed to struggle more, especially when it came to cleaning larger spaces.
OVERALL | In a question of Braava Jet 240 vs. 380t, which is the better mopping robot? In my opinion, it’s clear that Braava 380 is the better robot mop. It has better navigation, better cleaning performance, and a longer run time. True, it’s around $70 more expensive, however, that seems like a small increase compared to the superior performance offered.
I suppose if you really just want to save the money and your floors rarely get super dirty, then the Braava Jet 240 can work, but if it was my money, I’d still get the Braava 380t.
iRobot Braava 240 vs. 245
Simply put? Nothing.
At least, that is what seems to be the case. The Braava Jet 245 only seems to be available at a handful of retailers (Walmart, Jet.com, a few others), where as the iRobot Braava 240 is available at a much larger selection.
I have not been able to find absolute confirmation, but it appears the Braava Jet 245 is more or less functionally the same as the Braava Jet 240.
What most likely is going on is Walmart and a few other retailers got iRobot to create a unique SKU (the Braava Jet 245) just for them. This may allow them to offer more aggressive discounts or market it in other ways that they otherwise could not with the Braava Jet 240. This is reinforced by the fact that Walmart and Jet don’t have the iRobot Braava 240 for sale at all, only the 245.
OVERALL | To sum up, there really doesn’t appear to be any difference between the Braava 240 vs. 245.
Using the Braava Jet 240 is extremely easy. The process is as follows:
- Insert a cleaning pad
- Fill up the water reservoir (if needed)
- Press clean
There is no physical labor required to use this mop. It’s as easy as choosing the cleaning pad you would like to use and pressing clean. The rest of the work is done by the Braava Jet.
When it comes to charging the battery of the Braava Jet 240, just pop it out of its slot and insert into the portable wall charger. Once it is fully charged up you can replace it back into the unit and you’re good to go.
Can Braava Jet Clean Corners & Baseboards?
The Braava Jet 240 maneuvers well, as it is an ultra small, lightweight unit.
The square shape and small size are among the most notable benefits of the Braava Jet 240. It’s able to easily squeeze into tight spaces that might otherwise not get cleaned.
Additionally, the square design allows it to clean baseboards and corners more easily.
The following table indicates the frequency at which you will likely want to replace the various parts and components of the mop. However, your individual experiences may vary
|Accessory / Part||Replacement Frequency||Replacement Cost|
|Cleaning Pad||As needed||Check Price|
|Battery||As needed, typically 2-3 years||Check Price|
- Change the cleaning pad – The damp and wet cleaning pads should be changed after every major cleaning cycle. The dry cleaning pad can last a little longer, since there is no water used during the dry sweep mode. Getting a set of washable cleaning pads is a must.
- Replace the battery – Once the battery dies, it will need to be replaced. iRobot’s warranty covers the battery for 1-year, but outside of that time frame you will be responsible for replacing the battery.
To maintain the Braava Jet 240 it will cost around $5 / year. This will cover replacing the battery every 3 years.
We didn’t factor in replacement cleaning pads into the annual maintenance costs. It seems crazy to buy iRobot’s disposable pads, when there is a washable alternative. For around $15 you can get washable cleaning pads that should last the life of the unit.
The overall value of the Braava Jet 240 is good, but not great. The price compared to the cleaning performance makes sense for the most part, but I would have liked to see a slightly stronger cleaning performance from the 240.
During our cleaning tests, this Braava struggled with the liquid test, which caused a bigger mess than we originally started with. Once we removed the liquid and tested the Braava Jet 240 against honey and mud, we saw a better performance, but there were some struggles around the honey. The honey was just too thick and sticky, therefore the mop was not able to fully lift it off of the surface.
That said, the Braava Jet 240 does an excellent job when sweeping, as well as mopping light to medium levels of dirt, dirt, and other messes. If you set your expectations accordingly I think most users will be happy, but it’s definitely not capable of deep cleaning.
Maneuverability is one of the strong suits of the Braava Jet, which really helps to win points. This unit is quite small, but moves quickly. Additionally, it is able to turn a full 360°, which helps it maneuver around your furniture and other obstacles with ease.
Warranty and returns are both in line with iRobot’s standard policies. The warranty is 1-year and the return period is 30-days, via Amazon.

The iRobot Braava Jet 240 is a versatile mop with the ability to mop and sweep your floors at the push of a button. This robot is designed to take all of the labor out of mopping, as it works to clean your floors on its own.
I would recommend the Braava Jet 240 if you’re looking for the following features in a mop:
- Want a robot mop – As a robot, the Braava Jet 240 is able to complete your mopping on its own. Simply add a cleaning pad and water, press clean, and you’re ready to rock and roll. The robot will do the rest of the work for you.
- Don’t need a bunch of bells and whistles – Although a robot mop, this is iRobot’s older, less developed mop. Therefore, there are not as many bells and whistles included with this specific unit. If you’re okay with more of a basic mop and don’t need the higher end model (the Braava 380t), this could be a great fit.
- Want a mop for everyday use – This is not a mop that should replace your primary mop, but it can be used every day for light mopping and sweeping. The downfall of this unit is its lack of force applied to the ground. The Braava Jet 240 does not apply enough pressure to lift extremely sticky substances, nor does it have a large enough cleaning pad to remove a large volume of liquid. It’s great for light and maintenance cleaning, but it’s not a replacement to your traditional mop.
