Roomba I3+ vs I7+: Review

Roomba I3+

iRobot Roomba i3+ EVO

The Roomba i3 Plus is a highly dependable robot vacuum that can take care of itself – nearly. It will automatically empty dirt from its vacuum and put it in bags placed in its charging dock.

It’ll transfer itself into the charging dock when its battery is low, and it can schedule cleaning to specific times, meaning there’s not much you need to do each week.

However, it’s costly, as the dock for charging is heavy, and you’re bound to pay for bags that regularly cost a lot of money.

Cleaning Performance Comparison

1. Robot’s Ability to Walk

Roomba I7 1

The IRobot Roomba i7 + comes with an area for cleaning of more than 185 square meters, and the Roomba I3 + has only 170 square meters.

With a 20-millimeters (0.78 inches) climbing capacity, both are perfect for thicker carpets and can conveniently pass over the threshold of a door (if less than 2 centimeters).

The i3+ model and the i7+ have dirt-detecting sensors. It’s a system that detects areas of high traffic, causing an ideal cleaner that goes over them a few times until the area is clear.

Each robot is equipped with numerous sensors to prevent them from hitting objects, falling, and keeping them within a distance of 10 millimeters away from furniture and walls.

2. Power

Both models have the suction power measuring 1800 Pa and an acoustic level of the 68 dB range.

3. Ability to Wash the Floor

Both models can sweep and suction. If you require mopping, use the Braava jet M6.

4. Treatment for Dirt

With a 500-milliliter dustbin capacity, the i7+ can hold greater amounts of dirt than the I3+, which comes with 400 milliliters of the dustbin.

Suppose the dust bin in the Roomba is full. The robot vacuum then returns to the dock for charging. The base then sucks the particles out of the container.

Once the Roomba has finished emptying the bin, it is returned to clean. The base can hold more than 30 bins for the robot, and you won’t need to empty it until after one month.

5. Ability to Vacuum and Sweep 

Roomba I7 4

Carpet Recognition: Roomba i7+ has sensors that recognize carpets. If the vacuum is placed on carpets, the vacuum’s suction power is up to the highest level that will automatically clean deeper.

The side brush and the back come with an additional side brush made out of rubber.

Unique Dual rubber brushes (Multi-Surface) don’t become entangled in pet hair. Brushes can be adjusted and flexed to maintain continuous contact with carpets and hard flooring.

Cleansing Brushes: Both are fitted with a clean brush with detachable tips. It is simpler to clean because hair tends to get stuck on the outside. Furthermore, the latest brush comes with 250% more bristles, which means it can pick up more.

6. Filter

In the lids of each dustbin, you will find a HEPA filter, which allows the robot to be safe for those with asthma and allergies. The filters in Roomba aren’t washable, so it is recommended to replace the filter once in every 3 months.

Feature Comparison

1. Activity Monitoring

After Roomba cleans it, you can see the results within the cleaning history. The two can’t be tracked in real-time; you are unable to see the location as the robot vacuums.

2. Create a Plan

Roomba I7 2

Roomba i3 + only has basic scheduling capabilities. It can only be scheduled to start working at a particular date and time during the work week.

Roomba i7+ features an enhanced scheduling option. Once you have mapped the map, it is possible to break the map into different areas and assign each an appropriate name.

This feature allows you to plan cleaning according to zones, areas, selected room cleaning schedules, etc.

Roomba i3 + doesn’t come with a digital wall feature, but you can purchase an additional virtual wall barrier that can create an area that is not accessible. The I7+ has an electronic virtual wall feature that helps create a clean zone. 

Zoned cleaning: The robot cleans in a specific zone

No-Go zone Keeps Roomba i7+ from certain zones.

Cleaning of rooms: It is possible to order (or program) to do a clean-up in a specific space or two.

3. Mapping

Contrary to robots that don’t have an outline of their location and cannot move until their batteries are exhausted, Roomba navigates efficiently. It goes between straight lines that cover the area of cleaning according to the map it creates.

Roomba i3+ uses a Gyroscope and an optic motion sensor to determine the home’s layout. Roomba i7 + has camera sensors. The camera is not able to work in dark spaces.

Roomba i3 + cannot save maps in memory, whereas Roomba i7 + can keep up to 10-floor plans.

4. Controls

Roomba I7 3

Manually operate it as the radio car. If you require the device to get to a certain location, you can use an app to control it remotely and monitor its motions by sending it wherever you’d like.

In addition, you can tap the map then the machine will head there. This is much more convenient to use than the remote.

You can also manage the two robot vacuums through voice prompts using Google Assistant Assistant and Amazon Alexa Support.

Design Comparison

roomba i3 1

The Roomba i3 + from iRobot measures 13.34 inches by 13.26 and 3.63 inches and weighs 15 pounds. Roomba i7 + weighs 7.44 pounds and measures 13.34” x 3.34” x 3.63”.

Battery Comparison

With a capacity of up to 1800mAh, Roomba I3 + can run for around 75 minutes and takes 90 minutes to fully charge.

Roomba i7 + has 3300 mAh batteries that can run for around 90 minutes. It will take around 180 minutes for a full recharge.

If the vacuums cannot complete all of the work on the same charge, they will return to the dock that charges.

A resume is a way to ensure that the robot resumes the same place it left off once charging is complete.

This function is ideal for large households, where it is impossible for the robot to completely clean the house in one charge.

Major Differences Between Roomba Robots the i7+ and the I3+

  4. For the IRobot Roomba i7 +, the biggest debris at nearly 0.2 Gallons is 57. While in the IRobot Roomba I3 +, the massive debris of 0.2 Gallons is 96.
  5. Barrier against allergens, North American wire cord-1, additional high-efficiency filter-1, and a bonus brush are just a few of the tools and accessories in the IRobot Roomba i7 +. The tools and accessories that come in the IRobot Roomba i3 + include the ability to clean your base, automate dirt removal, dirt management bags, and high-efficiency filtration.

Conclusion

THE FINAL ADVICE

This is the best option to consider if you own objects that you would like to keep an appropriate distance from Roomba or prefer to only vacuum a certain region.

The higher-end models have an extensive home-based substrate instead of the small charging station that comes with the I3 and the i7.

The robot’s home is large trash cans and an engine that drags the trash out.

Regarding the couch and the solid terrain vacuuming, the i3 is in line with its predecessor, the Roomba i7.

Each of them has an older sibling that has the addition of a plus after the appellation. The word plus refers to the idea that they are an automatic charging shore that empties.
