iRobot Braava Jet 240 Review: Best Mopping Robot

As we all know, iRobot is an industry leader when it comes to home cleaning robots. And, Braava Jet 240, a floor mopping smart robot, is one of their recent launches.

Dried stains, coffee spills, pet drools, Braava Jet 240 is designed to sweep and mop floor with the help of different cleaning pads. It is intended for smaller areas like bathroom and kitchen, and for not multiple rooms.

Overall, it is smart, navigates intelligently and is ideal to help you with daily mopping chores. It can adeptly perform damp sweeping, dry sweeping and wet mopping.


Let’s jump into the detailed review of iRobot Braava Jet 240

Simple Design:

The Braava Jet 240 flaunts a simple yet elegant aesthetics with White plastic encasing. It’s a two-wheeled smart robot with an inbuilt 150 ml capacity water tank and a front mop.

Compact square shape of the bot and iAdapt 2.0 Navigation System is meticulously designed to tackle tight spaces and corners.

The petite machine measures only about 7” x 6.7” x 3.3”. And, it becomes one of the lightest mopping robot to ever exist by weighing just about 2.7 lbs.

Control Panel:

Top panel of Braava Jet 240 features a backlit “Clean” button, which also doubles as a power button.

There’s a foldable handle for convenient pick up and portability of the robot. Right below this handle there is an opening to water tank and a “mop eject” button as well.

Just press this button and the Cleaning Pad will come off in no time. No need to touch the dirt or gunk whatsoever!

Battery performance:

Powered by a Lithium-Ion 1950 mAh battery, the Braava Jet 240 operates effortlessly and quietly. It can mop smaller spaces, right from 150 sq. ft. (in damp sweeping and wet mopping modes) up to 200 sq. feet (in dry sweeping mode).

The Braava Jet 240 comes included with a charger, rechargeable battery and 6 different cleaning mops.

Removable battery is housed in the rear panel. The battery run time is for up to few hours, depending on type of mopping used. And, the recharging takes about 2 hours.

Quite naturally, wet mopping mode will consume maximum battery due to Jet Spray operation.

There’s no charging dock provided here, unlike other robot vacuums. You need to remove the battery and fit it into the charger for recharging. This is also the reason why you cannot schedule Braava Jet 240.

Three Cleaning Modes:

Front panel has a small hole that sprays water in “wet mopping mode” ahead of the robot for precise cleaning.

Also, front panel acts like a bumper and moves up/down, forward/backward with the help of spring action whenever it bumps into obstacles. The integrated sensor informs the robot about the obstacle. Thus, robot tries to find other direction.

Underneath the bumper, there’s a holder to fit different mops. Braava Jet 240 comes with total six mops viz. 2 for damp sweeping, 2 for dry sweeping and 2 for wet mopping. Each mop is designed with a cutout pattern for sensor. This is so the robot knows which type of mop is installed.

Attach the Cleaning Pad onto the robot, and press “Clean”. Your Braava Jet will automatically start cleaning based on mop type attached.

  • Dry Sweeping will pick up small dirt and dust particles from the floor in single pass. Thereby, clearing and preparing the floor for wet mopping.
  • Damp Sweeping is provided to clean up liquid spills or dried up stains from the floor, if any, in two passes. This cleaning mode makes use of Vibrating Cleaning Head and Jet Spray to get rid of spills and stains.
  • Wet mopping is for thorough cleaning of the floor in three passes, as the robot will spray water on the area ahead and mop it nicely. Not only will the head vibrate, but it will also use back and forth mopping pattern for deep cleaning.

Smart Sensors:

Braava Jet 240 includes 3 types of sensors viz. 1 to detect floor, 1 to identify mops and 1 Cliff Detect sensor.

Altogether, these sensors work to avoid gaps, stairs, etc. and clean the area effectively. Braava Jet automatically shuts off after it has completed a run or if it gets stuck.

Braava Jet 240 works pretty well on regular floors, tiles as well as glassy surfaces.

Smart robot makes use of progressive zig-zag pattern to clean the entire area.

As it detects any wall, furniture or fixture, it will clean its surrounding area by moving around it. But, it won’t go over carpets or rugs. Virtual Wall™ Mode in Braava Jet 240 creates a virtual boundary to prevent the robot from entering certain areas.

Smartphone App Control:

You can control your Braava Jet 240 through smartphone via Bluetooth connectivity. All you need to do is pair it up with iRobot HOME app.

You can instruct your robot to start/stop cleaning, create virtual wall and even adjust water level for Jet Spray through this smartphone app. Adding to this, you can check battery status, cleaning errors, type of mop, obstacle problems in the app as well.

Impressive thing is that you can command it to perform “spot cleaning”, which is not possible through robot’s control panel.

Quiet Operation:

As for quiet operation, Braava Jet 240 ticks that point as it does not feature vacuum motor. Even the indicator tones are sober enough and do not feel annoying.

Wheels on Braava Jet 240 feature soft rubber treads for snug grip on any type of floor.

The Final Word

Bottom-line is Braava Jet 240 is an ideal robot to sweep and mop smaller spaces of your home. This compact robot really isn’t suitable to clean large dirt particles.

Silent operation, bunch of sensors and an onboard computer in Braava Jet is what makes it so efficient in cleaning tasks. It works on almost all types of hard floors and can smartly collect dirt, dust and pet hair.

Wet mopping, damp sweeping and dry sweeping, use any of the three cleaning modes here as per the condition of floor. Low price of Braava Jet 240 offers excellent value for money!
