One of the significant innovations by iRobot was the bin that self-emptied technology launched with the I series, which includes the Roomba 7150, Roomba i7 (7150) vs. Roomba i7+ (7550).

Cleaning is one of the vital tasks that must be performed regularly to keep the place clean and neat. Cleaning does not just improve the appearance of space; however, it also assists in the removal of any unnecessary materials that are in the area. The waste materials include wrapped wrappers that have been thrown away, packaging covers, wrappers, etc. 

The removal of dust is essential to cleaning. A lot of people are allergic to dust. Uncleanliness can cause a worsening of their health condition. It is therefore vital to keep the space tidy and clean. The traditional methods for cleaning floors include sweeping using Broomsticks.

The two models have been quite confusing. Today we will discuss the two models. With this Roomba i7 and i7+ review, we’ve discussed the differences in depth and offered our advice for the best option.

If you cannot do it, here’s the short version. The i7 doesn’t have an auto-emptying docking station and is less expensive.

What Are the Differences?

Let’s remove this from the way. You can choose between two models when you purchase the most recent version of Roomba, the Roomba range. Are you going to choose the i7 or the more expensive i7+? There’s more than just cost in the models.

In addition to the price tag, there are only two distinctions:

  • The collection bin, as well as
  • A charging station.

We can determine what this signifies now that we understand what they are.

Roomba I7 vs. the i7+ Face-to-Face Comparison

Roomba I7 4

In this segment, we’ll examine the two Roombas through a look at their significant attributes and how they differ. With that said, we’ll get right to work.

Design and Aesthetics

As a prospective buyer, you must be able to distinguish between these two models based on the design. It is also essential to purchase one with a low-profile design to ensure that it can slide under sofas, chairs, and other low-profile furniture, where the majority of dirt can be found.

In terms of style, the two models look the same. They both have 13.34-inches diameter and measure 3.63-inches.

However, overall the i7+ is more spacious since it has the CleanBase unit that measures 19-inches tall and 12.2-inches wide.

For appearance, they’ve completed in black and some metallic accents. The top interface comprises three buttons: a big CLEAN button in the middle and two smaller Home and Spot mode buttons on opposite sides of the clean button.

Cleaning Performance

Which Roomba of the two has the highest cleaning efficiency? This is what we’re going to discover within this section. We’ll also share the cleaning test results that we have compiled.

Cleaning Orientation

Roomba’s i7 and i7+ are designed to vacuum and sweep only, So don’t expect additional features like mopping. Even the most expensive Roomba currently available, the S9 and the S9+, do not include mopping features like we’ve seen on other brands, like Roborock or ECOVACS.

In terms of their use, they are very similar. They can be used to clean floors (hardwood tiles, linoleum, tile vinyl, and so on) and low- to medium-pile carpets. They also excel at collecting pets’ hair (short and long hairs of pets) without a problem.


Roomba I7 5

The filtering system is an excellent point to discuss when comparing the two robot vacuums. In this article, we’ll look at two aspects: filters as well as the capacity of the dust bin.

Roomba I7 and i7+ feature high-efficiency filters which aren’t HEPA certified; however, they will accomplish the task. Contrary to other AeroForce filters available, this one is smaller yet packs the same power.

Concerning the bin size, the two models are similar in size. They have an 0.3L bin and a full bin indicator.

Automatic Self-Emptying

The buzzword in the world of robot vacuums is self-emptying bin technology. This is a technology that transforms robot vacuums into completely automated machines.

The Roomba i7 and i7+ both consist of self-emptying features. It automatically empties the bin whenever it docks. This means that users don’t need to be concerned about emptying the bin now and later because the unit can store a month’s worth of dirt.

Although both Roombas use self-emptying technology, there’s a distinction in the type of accessories included. Roomba i7 does not come with a CleanBase unit, whereas the i7+ is equipped with this feature.

Battery and Runtime

The battery of robot vacuums determines the duration of their runtime and, in turn, the amount of floor space they can clean with one charge. It’s also essential to evaluate factors like power management and life-cycle.

Roomba I7, as well as i7+, look remarkably like each other in this regard. They are both equipped with 1800mAh lithium-ion batteries designed to last for 75 minutes and then recharge for 2-3 hours.

In terms of power management, both vacuums come with the auto-recharge feature and resume meaning that they dock automatically to charge. 

When fully charged, they will begin cleaning again without further prompting. In terms of lifespan, the battery can last for 12- 18 months, subject to usage.

Navigation and Mapping

The battery decides on the space the robot vacuum can clean. The map and navigation system decides the areas the robot can reach and the cleaning efficiency. Navigation is the robot’s process of navigating through your home, while Mapping is about scanning the area and mapping the cleaning pattern.

Roomba, the i7, and i7+ come with the exact Mapping and navigation systems. Both come with the iAdapt 3.0 navigation. It is a technique based on the VSLAM (Visual Simultaneous Mapping and Localization) algorithm. 

There’s a set of sensors for detecting obstacles and for detecting cliffs that integrate with a real-time camera. Compared to Roombas, which depend on SLAM algorithms alone, the pair is highly accurate in areas with high traffic and houses with many rooms.

Regarding maps, Roomba i7 and i7+ are equipped with an advanced floor scanning system and mapping system called Imprint(TM) innovative Mapping.

This add-on allows the robot to recognize different rooms and store maps. You can instruct Roomba Roomba to wash the kitchen area only, not the whole home. This is the last thing to consider, as both Roombas use Virtual Walls.

Smart Features and Convenience

In the age of intelligent homes that are taking place, you must have an advanced Roomba which can connect to other devices, such as your smartphone. The Roomba i7 and i7+ are very smart and have the same features and functions.

You can operate via your mobile device thanks to the iRobot HOME app, which is available for Android or iOS devices. Apart from smartphone control, these two Roombas can integrate with voice assistants, such as Alexa and Google Assistant.

For efficiency, both feature the scheduling function. The name says it all; the scheduling function lets homeowners program the vacuum cleaner to operate their home at specific time slots. You can program them to clean for seven consecutive days.

Can We Upgrade From an I7 to an I7+ Later?

Roomba I7 1

If you purchase an I7 and decide later that you’d prefer an i7+, you can upgrade yourself. Since the vacuums are the same (except in the case of dust collection), it is only necessary to buy a Clean Base’s Dirt Removal System. 

You can receive the clean Base if you buy this item, a brand new collection bin, and a starter bag to fit this Base’s tower. You should get a new bin of collection because Clean Base requires a rubber cover on the bin to ensure that it can collect dust without the assistance of humans.

Switch the collection bin inside the i7 to the new one, then plug into your Clean Base, removing the Home Base, of course, and you’re done. You’re today the proud proprietor of the Roomba i7+.

This is a great bargain for those looking to save money in the beginning since the first costs for both models are roughly $250.

Once you’ve purchased the i7 to save money, You can buy a Clean Base. The clean Base system for the upgrade cost around $300. The difference of $50 is not significant for those who want to save some money initially or make “installment” payments to get the i7+ model.

Are the Vacuums Themselves Exactly The Same?

Apart from the charging bases and bins for collecting, The two robots have the same components. This includes the wheels, motor extractors, and all other internal components.

The only difference between the robots is where the dustbins are placed in. The memory is identical, and the connectivity to wireless networks and the use for mobile apps, the iRobot mobile application, and voice commands and controls are all the same.

Will the Two Models Use Either Charging Station?

When you recharge the batteries, the Home Base and the Clean Base can restore each other.

The most crucial issue is the detectability of the Clean Base of the rubber flap seal that is on the bin for collection. If it’s detected, it will trigger the Clean Base to vacuum out the bin’s contents. It won’t perform anything other than charging the robot’s battery if it’s not seen.

In theory, you could use the i7 or the i7+ to charge at any station. This is important given that the robot can keep up to 10 different floor plans. It is possible to purchase the i7 and purchase a Home Base, then upgrade to the i7+ after purchasing the Clean Base.

Doing this will give you two charging stations that can be stored in different places. Transferring this robot to another location allows it to tidy up the floor plan and use its Home Base to recharge. Return it to the original location, and it will wash there and empty the contents of the Clean Base while recharging.

Can We Downgrade to the I7?

There is currently not any way to upgrade. iRobot might, shortly, offer the i7 collection bin as an individual item or the Home Base with a collection bin as a kit; however, as of the moment, they have no plans to do so.

You’d just require the bin, but without the hole for a downgrade. Clean Base handles all of the excellent dirt removals. Clean Base. If you do not want to utilize the automatic emptying feature, it’s unnecessary; however, it’s more convenient (and cheaper) to buy the i7 and upgrade later than buying the i7+ and then deciding to upgrade.

Which One Should We Buy?

The individual makes the purchase decision based on the differences in price and the dirt disposal system; the decision is open to both.

We would recommend purchasing the i7 model as it’s more affordable. You’ll save around $250 upfront and also have the best vacuum for cleaning your floors.

There is also the option to upgrade in the future by buying an upgrade to the Clean Base system with an overall price difference of around $50.

There is nothing else for purchasing the i7+ in comparison to the i7 since the two robots have the same features and provide the same advantages, except the automatic clean-up of the bins, which is obvious.

Due to the amount you save using the i7, it’s practically a no-brainer to select this choice. However, in the end, it entirely depends on you, and regardless of which route you decide to go, you’ll be content with your decision.

Our Verdict: Roomba i7 vs. i7+

As we mentioned before, these two Roombas are very identical. They’re just different in that the Plus model is equipped with a cleaner unit. So, the main issue is: should you go with the Roomba I7 or the i7+?
