Roomba E5: Review

Roomba E5 vacuum cleaner

The iRobot Roomba e5 robotic vacuum is among the latest models launched by iRobot. The robotic vacuum is equipped with high-performance performance, intelligent features for homes, and a mid-range price. 

It looks like an upgrade that is a version of Roomba 890 to us. The specs, as well as the software and pricing, are identical to the 890. However, the cleaning capabilities of the e5 are an enormous improvement.

The e5 is an excellent option if you don’t require the latest capabilities but still require exceptional cleaning performance.

  • Can recharge itself to restart cleaning
  • It has WiFi connectivity, which allows people to manage the vacuum using their mobile phone or another compatible voice device.
  • Cleans well
  • It offers a strong cleaning performance and a variety of interesting features.
  • Affordable
  • It can navigate its way around easily.
  • Not too loud
  • No alerts about a full dustbin
  • Small dustbin
  • The e5 can’t recharge or return. Once the battery has died, the vacuum will recharge and stay in the base.
  • Doesn’t have an onboard camera used to create maps of your home.
  • Cleansing is more random and less systematic.

Roomba i3: Review

irobot roomba i3

The Roomba i3 is a highly dependable robot vacuum cleaner that takes care of itself – nearly. It will automatically empty dirt from it into baggies that are placed in its charging dock.

It’ll transfer itself back to charge when it gets low, and it’s possible to schedule cleaning according to specific times, meaning that you’ll have nothing to accomplish from week to week.

But it’s pricey, the charging dock is large, and you’re obligated to pay for costly bags regularly.

  • Affordable price
  • It follows a pattern of systematic cleaning.
  • Uses a floor-tracking sensor to help navigate
  • Dual rubberized main brush
  • Amazing suction power
  • A little too loud
  • Small dust bin
  • Sometimes, it is stuck.
  • The auto-empty bin can be purchased separately.
  • The map is not configurable.

We have compared two models and all of the differences in terms of specifications, features, and similarities here:

The Key differences

Differential 1: The Roomba i3 can “recharge and resume,” but the e5 does not.

Because it can tell exactly where it is relative to your house, it comes with its “recharge and resumes” feature, normally only available on top robotic vacuums.

If the i3 detects a low battery in cleaning, it will be able to remember the area is cleaned, then return to the docking station to charge its battery, then begin cleaning from the area it stopped. The e5 isn’t able to do this.

This is a different feature that we recommend most customers consider when making a purchase decision. We were pleasantly amazed to see iRobot included this feature in their announcement of the i3. It makes the decision between the two vacuums simple.

Differential 2: The Roomba i3 features intelligent navigation, while the Roomba E5 doesn’t.

The Roomba i3 can navigate your home in a rational manner which means that it vacuums less or more straight lines and can navigate around obstacles just like humans could.

This is different from the e5’s randomly “bump and turn” style navigation, which flits around randomly until the whole flooring is entirely covered.

Smart navigation is quite an important feature, and because of this, we would suggest buying the i3 instead of the e5.

Differential 3: The Roomba I3 Robot is compatible with the iRobot self-emptying base. The e5 isn’t.

You get Roomba i3 in a different version called the i3+. This complete model includes the self-emptying docking station known as”the home base.”

As you’re probably aware, the home base creates it so that you don’t have to manually empty the Roomba’s garbage bin. Instead, the dust gets collected in the garbage bag located inside the base of the home after cleaning.

Although this is great, it means that you will need to purchase disposable bags to replace them now and then. The bags used for disposal are not recyclable.

If you’re not keen on self-emptying home bases, the difference isn’t a big deal to you. For clarity, the i3 does not include an auto-emptying base. Only the i3+ has it.

6. Mapping, Boundary Marking, and Navigation

As you might have guessed, robotic vacuums can operate autonomously, which is not the case with vacuum cleaners and hand-held models.

They are linked to smart systems that permit the robots to navigate the way to your home and, more importantly, to be safe from accidents.

They also assist the robot plan efficient cleaning patterns that will ensure the highest level of cleaning. Therefore, with no further delay, here’s how the two robot vacuums are compared.


iRobot Roomba E5 1

Roomba E5 can be called an entry-level robot vac that runs on the IAdapt 1.0 Navigation system. It’s a SLAM-based method that relies on sensors for localization.

There are sensors to detect obstacles as well as an adjustable bumper. If the sensors spot obstructions, the machine alters the direction of travel.

The bumper retracts and absorbs the impact force if the robot comes into contact with an obstruction. Anti-drop sensors are also present to stop the machine from falling down the staircase.


The Roomba i3 and Roomba i3+ are also equipped with the “iAdapt” 1.0 navigator. There are sensors for obstruction detection and stopping the machine from dropping down the steps. The i3 series models have a retractable bumper that can minimize the impact when they hit an obstruction.

In a home with low traffic, it isn’t stuck as the E5; however, expect the robots to strike barriers everywhere in busy homes.

Is the Roomba E5 Worth buying?

iRobot Roomba E5 5

Yes. It is true. Roomba E5 is a tremendous robot vacuum for people on a tight budget. The robot vacuum is reasonably priced and can provide excellent cleaning on floor surfaces that are not cleaned.

It can also handle pet hair with ease, comes with intelligent features to make life easier, and comes with the Dual-Mode Virtual Wall(r) barrier to ensure it is contained.

Hence, it is, however, not the best choice for carpets due to its weak suction power. So, it can also cause problems in larger apartments due to its lack of a sophisticated mapping system.

It simply does its cleaning randomly and can be unable to locate certain places.

Is the Roomba i3 Worth buying?

The Roomba I3 and Roomba I3+ prove to be great robot vacuums. They’re well capable of handling any kind of flooring, including pet mess. What’s more? The higher suction is ideal for carpets with low piles.

Another advantage of this robotic vacuum is the auto-emptying bin that automatically cleans it. You do not need to worry about emptying the bin by hand after each cleaning session.

The vacuum can recharge and resume independently and includes iRobot Genius Home Intelligence.

Talking about the negative side, the i3 doesn’t come with the Virtual Walls barrier, so it is necessary to invest more money in the nodes if you require this feature.

Additionally, the navigation of the i3 isn’t up to standard, but given the price, it’s still worth your money.

Roomba E5 vs. i3: Expert’s Verdict


After all, it’s the Roomba I3 and Roomba i3+ that rule through the night in the hot comparison review. The i3 series comes with increased suction power, self-emptying bins, systematic cleaning routines, iRobot Genius Home Intelligence, and an auto-resume option.
