iRobot Braava Jet240 Mopping Robot Review

All of the robot mops I’ve covered so far use a built-in water tank system that these machines use to make the microfiber mop underneath damp or keep it damp.

iRobot Braava Jet 240 Review

From the top of the line Braava 380t to the cheaper ILIFE robot vacuums and mops, all of these utilize a similar system. These machines a water tank on top that use gravity to soak the towel attached underneath.

One thing Braava has over the other brands is its advanced navigation that has a back-and-forth mopping motion.

Other brands merely drag the mop over the surface

The Braava Jet is unique. Instead of water dripping under the water tank, it squirts water up front and then mops the area then repeats the cycle until it finishes.

The cleaning pattern is similar to the Braava 380t but it uses a different kind of cleaning cloth.

It does not use a washable microfiber cloth, instead it uses a disposable pad pre-soaked with cleaning solution. In terms of cost, it’ll will cost more in the long term because you’ll have

That’s the convenience that these provide at the cost of around $7 per 10-pack of these mops. But if you feel like it’s an added expense and you are okay with soaking a reusable pad then you can purchase the blue microfiber pad and pre-soak it yourself.

What to expect from this floor scrubbing and spraying robot?

The Braava Jet is iRobot’s cheapest robotic mop and sweeper available in the market right now at just under $170 in Amazon and iRobot’s store.

Before moving any further watch this video to get a feel what this robot mop is all about, what’s inside the box and how it works…

Three cleaning modes

Take note that this robotic cleaner does not have any vacuum motor. It is purely a mopping robot with 3 modes that the robot automatically detects depending on the mop you attach.

How does the robot know what mode to use? Well underneath each pad is a paper cutout pattern that the robot scans and automatically detects.

These cleaning modes are the dry sweeping, damp sweeping and wet mopping…

Dry sweeping:  This mode comes on when the dry sweeping pad is on. In this mode the robot goes in a straight pattern without spraying any water. The dry pad will attract any fine dust, dirt or hair and this will work on all hard floor surfaces.

Damp sweeping: To access this mode, use the pink pad. It will have a similar cleaning pattern as it would have in dry sweeping mode but the mop will vibrate and the sprayer will squirt water to activate the cleaning agent. Use this when cleaning sealed floors.

Wet mopping: Slide in the blue mop and the wet mopping mode comes on. This mode will provide the most agitation and will be able to clean out relatively fresh coffee stains. Not only will the mop vibrate, it also activates the back and forth mopping motion after the sprayer squirts water to activate the cleaning solution in the blue pad.

What if I don’t like to buy disposable pads?

If you feel that disposable pads are too costly or impractical, iRobot provides you with an alternative. You can purchase the blue washable wet mopping pads instead of the disposable ones for around $18 for a pack of two.

These pads will last for around 150 to 200 uses and you simply spray on the cleaning solution on the pads before letting the robot do its thing. In my opinion these pads are the most cost effective solution in the long run for wet mopping.

And leave the cleaning to a robot vacuum instead.

Efficient Navigation

This robot mop actually uses the same iAdapt 2.0 navigation system found in the Roomba 980, this means a fast and efficient cleaning pattern that will systematically go back and forth until it finishes the area you want it to clean.

In dry mode, this robot will be able to clean around 200 square feet. In damp mop or wet mopping mode that number goes down to 150 square feet.

So this robot will be able to clean one small area at a time and does not have multi-room cleaning capabilities which I think is a good think because the pads will be too soiled by then.

Battery

Unlike the Roomba or the Braava 380t where the battery is built in, the Braava Jet’s battery is removable and is charged through a wall pluggable charger similar that’s similar to a digital camera.

It only takes 2 hours to recharge and will cover between 150 to 200 square feet.

Water Tank

Braava Water Tank

This robot has a 150ml water tank that sprays water in front of robot. I like this setup because water is used more efficiently compared to robots that use a dripping mechanism to keep the pads wet.

Cleaning Performance

Before showing you how this robot mop cleans, watch this video to see how different this is from the Scooba…

You’ll notice that with the Scooba that it takes longer to prep. Post cleaning steps are also different. With the Braava, just remove the pad, throw it in the trash and you’re done. Scooba has multiple steps from removing the tank, cleaning filters, etc. This is a big reason why Scooba is no longer in production even if it cleans more thoroughly.

Here’s another video of the Braava Jet in action this time on tile.

It’s basically a time lapse video that shows how this robot will navigate and how it will handle dried stains…

Based on the video it didn’t completely remove the stains. For stains such as these you may need a stronger cleaning solution or make your own and use the blue pad that is washable. In terms of navigation it looks to be efficient as it does not go in a random direction.

Here’s how much dirt a microfiber pad can pick up…

Dirty mop

I wouldn’t suggest using this to clean up such mess as it could scratch your floors.

Consumer Reviews

This robot has gotten mixed reviews. Some like the mopping motion while others said it did squat. But if you read carefully, those who gave high ratings used this for it’s intended purpose which is relatively clean surfaces.

It is an in-between cleaning tool that is a finishing step after you vacuum. This would be a great tag team partner to a Roomba 980 or 650 or any robot vacuum you have.

Since it is compact, it will reach into tighter places compared to the larger Scooba or Braava 380t.

Some consumers did not like that fact that this did not come with reusable pads. But you can buy reusable pads from Amazon so that option is available.

As for the dry sweeping feature, don’t expect it to clean more than moderate messes. A robot vacuum would be a better option.

I must warn you that if you have black flooring, this may not work well on it as some consumers have shared.

When utilized properly this robot is a great and relatively cheap option to the more expensive Braava 380t with a similar navigation pattern minus the cube.

Where can I buy this?

You can buy this in Amazon for less than $170 and it is eligible for their free 2-day shipping if you join Prime.

Amazon also sells extended warranties of up to 3 years if you want that extra peace of mind.

To wrap up

This robot mop is a great option for home owners looking for an affordable and smart mopping option. But you have to remember that this is basically a Swiffer that does the mopping for you.

You have the option of buying reusable pads if you want to save on the cost of buying disposables. Just buy a good cleaning solution that you can spray on the mop.

It has a relatively efficient navigation that uses the same iAdapt 2.0 system found in the Roomba 980. A full charge will clean an area between 150 and 200 square feet but some consumers reported that this robot does not clean that much floor space.

This robot is great to use on relatively clean floors. On really dirty surfaces, you’ll need a hard floor cleaner.

Make sure to use a fast drying cleaning solution that does not streak and use distilled water to avoid water marks.

This robot will work best on surfaces like granite and tile where you’ll see the benefit of the mopping motion.
