Pros

  • D-shaped body style offers improved cleaning performance
  • Wider cleaning path
  • Imprint smart mapping + link technology

Cons

  • Expensive price point

Roomba S9+ / S9 Design

The design of the S9+ and S9 is pretty unique compared to previous Roomba models, for a number of reasons. Some of the highlighted features are listed below:

D-Shaped Body

The Roomba S9+ and Roomba S9 are currently the only two Roomba models that have a D-shaped body style. This shape is designed to have better cleaning performance along edges and corners while also navigating more efficiently.

The D-shaped body also allows for a wide brushroll, since the brushroll is located closer to the front of the vacuum instead of being positioned between the wheels.

Imprint Smart Mapping + Link

The S9+ and Roomba S9 also come integrated with Imprint technology, which includes two parts:

  1. Imprint Smart Mapping
  2. Imprint Link

Imprint Smart Mapping allows these vacuums to create digital maps of your space. The S9+ and S9 also have the ability to set up advanced Zoned Cleaning.

The Imprint Link technology pairs the Roomba robot vacuum with the new Braava Jet m6 mopping robot (read our Braava m6 review). If you are interested in a duo mop / robot team that works together, Imprint Link technology lets these two devices alternate which one cleans which spaces.

First, the Roomba S9 will clean the space. When it is done, the vacuum can digitally communicate with the m6 mopping robot to let it know what it is time for mopping.

October 2019 Update – several weeks ago iRobot released an update for s, i, m, and 900 series robots, allowing these models to now take advantage of Keep Out Zones. These keep out zones can prevent Roomba from entering certain rooms or areas of your home. You can activate Keep Out Zones via the iRobot app.

App Control

The Roomba S9 and S9+ can both be controlled via app when connected to a wifi network. The app control works the same as other app-controlled Roombas, like the Roomba 980, Roomba 690 or the Roomba 675.

How big is the Roomba S9?

The Roomba S9 and Roomba S9+ both have the same size body. The robot vacuum is:

  • 12.25″ diameter
  • 3.5″ tall
  • 8.15 pounds

How long can the Roomba S9+ / S9 run?

The Roomba S9+ and S9 both have a run time of 75 minutes per cleaning cycle.

These models are also equipped with Recharge & Resume which allows for two additional cleaning cycles within a single run.

This increases the combined run time to up to 225 minutes, spread out over 3 separate cycles.

Roomba S9+ / S9 Differences

The main difference between the Roomba S9+ and the S9 is the charging base. The charging base on the S9+ is the CleanBase, which has the ability to automatically empty the dust bin as it fills up.

There is a disposable dust bag designed into the CleanBase. When the robot vacuum docks back at the base, suction power relocates the debris from the dust bin canister on-board the vacuum into the dust bag in the charging base.

Roomba S9+ / S9 Cleaning Performance

The Roomba S9+ and S9 models are new to the robot vacuum market and have not gone through the complete Modern Castle testing process.

That being said, we have run complete tests on comparable models, like the Roomba i7+ and Roomba i7.

Roomba S9+ edge cleaning

According to Roomba, the S9 has 40x the suction power (of the Roomba 600 series) while the Roomba i7 has 10x the suction power.

For this reason, we would expect the cleaning performance of the S9 to be as good, if not better than the performance of the i7.

But I’ve got to admit… the cleaning scores for the Roomba were near perfect all ready so I’m not sure the higher suction power would have even been that noticeable in our cleaning tests.

Roomba i7+ vs. i7

The Roomba i7 series are two vacuums that were released before the Roomba S9 series. Unlike the S9 which has the D-shaped body style, the Roomba i7 series still has the classic round body style.

Features also vary between the these two different series types. Let’s jump in.

Imprint Technology

The Roomba i7 series has the same Imprint smart mapping and Imprint link technology as what is on the Roomba S9. This technology allows for zoned cleaning cycles and improved navigation.

Imprint Link technology makes it easy to use the Roomba i7+ or Roomba i7 in conjunction with the Braava Jet m6 mopping robot.

App Control

Like the Roomba S9, the Roomba i7+ can be controlled from a wifi-based app, accessible from any smartphone. It uses the same iRobot Home app as the S9 series and other Roomba models.

From the app, you can:

  • Schedule a cleaning
  • View digital map
  • Set up cleaning zones
  • See cleaning performance

How long can the Roomba i7+ / i7 run?

Similar to the Roomba S9 series, the Roomba i7+ series can run for up to 75 minutes for each cleaning cycle. It also has Recharge & Resume which allows it to run for two additional cycles (returning to the last spot it cleaned each time).

Recharge & Resume combined with digital smart mapping, the Roomba i7 series is able to more efficiently clean the entire space.

Roomba i7+ / i7 Differences

Similar to the Roomba S9+ and Roomba S9, the i7+ and i7 Roombas have one main difference.

The charging base.

Self-emptying CleanBase charger

(comes with the Roomba i7)

The Roomba i7+ comes with the larger CleanBase charging base (specs listed above) and the Roomba i7 comes with the standard low-profile charging base.

The CleanBase charger is significantly taller than the standard charging base and also has the on-board dust bag, which can hold up to 30 loads of debris from the on-board dust bin on the vacuum itself.

Roomba i7+ / i7 Cleaning Performance

The cleaning performance of the Roomba i7+ / i7 is exceptional across all floor types. Compared to the Roomba S9 it does have less powerful suction (40x on the S9 vs. 10x on the i7 — compared to the Roomba 600 series).

Roomba S9 vs. Roomba i7 Differences

Wondering about differences between the newest Roomba S9 and the slightly older Roomba i7?

Roomba S9

Roomba i7

The main differences between the S9 vs. i7 models are:

  • BODY STYLE: The Roomba S9 has a D-shaped body while the Roomba i7 has the standard round Roomba body style.
  • SUCTION POWER: The Roomba S9 has 40X the suction power (compared to the Roomba 600 series) while the Roomba i7 has only 10X the suction power.
  • SPINNING BRUSH: The spinning brush on the S9 is located right at the corner and is designed specifically for cleaning corners, with shorter bristles. The spinning brush on the i7 has longer bristles to help capture more debris and pull it into the cleaning path of the central brushroll.

Roomba e5

The Roomba e5 is one of the newly released models that comes in as more of a budet choice compared to the i7 and S9 series.

This robot vacuum does not have the option to include the self-emptying CleanBase charging station, but it does have a number of nice features and is an excellent value.

Pros

  • More reasonably priced than the S9 or i7 series
  • Great cleaning performance on all floor types

Cons

  • No on-board camera so the performance of the navigation may be slightly diminished
  • No Recharge & Resume function

Roomba e5 Design

The Roomba e5 has the classic round body style with familiar button controls and wifi connectivity.

Like the Roomba i7, there is a central “CLEAN” button with smaller buttons on each side – one for Spot Cleaning and one to send the vacuum back to the charger.

There is no on-board camera on the Roomba e5.

The bottom of the e5 contains the rolling brushes, wheels, spinning brush, and dustbin
For comparison, here is the old brushroll style, located between the wheels.

Also similar to the i7, the brushrolls are located between the two large wheels, resulting in a narrower cleaning path than the Roomba S9, but still powerful performance.

App Control

Despite the lower price point, the Roomba e5 does have app-based control when paired with a local wifi network.

The app allows you to schedule a cleaning and start / pause a cycle.

The Roomba e5 does not have Imprint technology so there is no digital mapping or the ability to pair the e5 with any robot mop, like the Braava Jet m6.

How big is the Roomba e5?

The Roomba e5 is:

  • 13.3″ diameter
  • 3.6″ tall
  • 7.2 pounds

Roomba e5 Cleaning Performance

The cleaning performance of the Roomba e5 was excellent across all flooring types, capturing between 98-100% of each debris tested.

We ran a total of 12 cleaning tests, 4 on hardwood, 4 on low pile carpet, and 4 on high pile carpet. We tested the e5’s ability to clean cereal, rice, kitty litter, and sugar for a wide variety of debris sizes and densities.
