The iRobot Roomba series continues to be a top choice in the robotic vacuum market, offering a range of models that cater to various needs and budgets. Two models that have garnered attention are the Roomba i4 and Roomba 694. Both vacuums offer solid cleaning performance and smart features, but they differ in several key areas such as navigation, cleaning power, and advanced functionalities. In this comparison, we’ll break down the features, pros, and cons of each model to help you decide which one is the better fit for your home.


Design and Build Quality

Size, Weight, and Aesthetics

Both the Roomba i4 and Roomba 694 have a similar design, with a circular, compact body that allows them to navigate under furniture and around obstacles. They are both sleek, black robots that fit well into any modern home decor. The size and weight of both models are nearly identical, making them easy to store and maneuver in tight spaces.

Dimensions 13.4 x 3.63 inches 13.4 x 3.63 inches
Weight 7.44 lbs 7.44 lbs
Finish Black Black

Both models are of a similar size, so there’s no major difference in terms of physical design. However, the i4 has a slightly more refined build, reflecting its position in the i-Series, while the 694 is part of the more affordable Roomba 600 series.


Cleaning Performance

Suction Power and Cleaning System

The Roomba i4 and 694 are both equipped with iRobot’s AeroForce® 3-Stage Cleaning System, which includes dual multi-surface brushes and a strong suction system designed to pick up dirt, debris, and pet hair. However, there are slight differences in the efficiency of each model’s suction power.

Cleaning Aspect Roomba i4 Roomba 694
Suction Power High Moderate to High
Brush System AeroForce® Dual Brushes AeroForce® Dual Brushes

Both vacuums handle hardwood floors and low-pile carpets effectively, but the Roomba i4 has a stronger suction capability, which allows it to pick up more debris and clean more efficiently on medium-pile carpets. The 694 is designed more for basic cleaning tasks and may require a little more time to clean deeply.

Performance on Various Surfaces

Surface Type Roomba i4 Performance Roomba 694 Performance
Hardwood Floors Excellent Excellent
Low-Pile Carpets Excellent Good
Medium-Pile Carpets Good Fair
High-Pile Carpets Fair Poor

The Roomba i4 excels in homes with medium to low-pile carpets, whereas the Roomba 694 is best suited for hardwood floors and low-pile carpets. If you have high-pile carpets or heavy pet shedding, the i4 will likely perform better.


Navigation and Mapping

Navigation System

One of the key differences between the Roomba i4 and 694 lies in their navigation systems. The i4 features iAdapt® 2.0 Navigation, which ensures systematic cleaning by guiding the vacuum in a more organized pattern. However, it doesn’t offer advanced mapping or room-specific cleaning.

On the other hand, the Roomba 694 also uses iAdapt® 2.0 Navigation, but with fewer optimizations. It moves in a more random pattern, which may result in less efficient cleaning, particularly in larger rooms or spaces with a lot of obstacles.

Navigation Feature Roomba i4 Roomba 694
Navigation System iAdapt® 2.0 iAdapt® 2.0
Cleaning Pattern Systematic Random

While both models use iAdapt® 2.0, the i4 offers more efficient navigation due to its more refined movement and ability to clean spaces in a systematic manner. The 694, however, may take longer to clean larger areas due to its less methodical approach.


Battery Life and Runtime

Runtime and Recharge Features

Both models provide similar battery life, lasting approximately 90 minutes on a single charge. When their batteries are low, both vacuums return to their charging stations, recharge, and resume cleaning where they left off.

Battery Aspect Roomba i4 Roomba 694
Runtime ~90 minutes ~90 minutes
Recharge and Resume Yes Yes

Both vacuums are suitable for homes of small to medium size, but may require multiple cycles to complete cleaning in larger areas. The “Recharge and Resume” feature ensures that both models can clean uninterrupted, though larger homes may need more time.


Smart Features

Wi-Fi Connectivity and Voice Control

Both the Roomba i4 and 694 offer Wi-Fi connectivity, allowing you to control the vacuum remotely using the iRobot Home app. This feature enables scheduling, progress monitoring, and the ability to customize cleaning preferences. Both models also support voice control through Amazon Alexa and Google Assistant, allowing you to start, stop, or schedule cleanings using simple voice commands.

Wi-Fi Compatibility Yes Yes
App Control Yes Yes
Voice Commands Alexa/Google Alexa/Google

The app and voice control features are similar in both models. However, the i4 provides a slightly more refined experience thanks to its more advanced cleaning system and systematic navigation.


Maintenance and Accessories

Dustbin Capacity and Filter System

Both the Roomba i4 and 694 come with a 600 ml dustbin and high-efficiency filters that trap dust, allergens, and other fine particles. The dustbin size is large enough for most cleaning tasks in a small to medium home, and the filter system in both models is effective for general household cleaning.

Maintenance Aspect Roomba i4 Roomba 694
Dustbin Capacity 600 ml 600 ml
Filter Type High-Efficiency High-Efficiency

Both models require regular emptying of the dustbin, and the filters will need to be replaced periodically. The maintenance for both vacuums is simple and easy to manage, making them low-maintenance options for busy households.


Price and Value

Aspect Roomba i4 Roomba 694
Price Range Moderate Budget-Friendly
Value for Money Excellent Excellent

While both vacuums offer excellent value, the i4 sits at a higher price point due to its enhanced cleaning system, more efficient navigation, and better performance on a variety of surfaces. The Roomba 694 is a more budget-friendly option, ideal for smaller homes or simpler cleaning needs.


Who Should Choose Which?

Final Verdict

The Roomba i4 and 694 are both fantastic robotic vacuums, but they cater to different needs and preferences. If you’re looking for an affordable, reliable option for light cleaning tasks in smaller spaces, the Roomba 694 is a great choice. It offers solid performance on hardwood floors and low-pile carpets, along with convenient app and voice control features.

However, if you need a vacuum that can handle more demanding cleaning tasks, such as medium-pile carpets or larger homes, the Roomba i4 is the better option. Its superior suction power, more efficient navigation, and better overall performance make it a more versatile choice for homes with pets or larger areas.

  • Choose the Roomba i4 if you need a more powerful vacuum that can handle a variety of surfaces, especially in medium to large homes or homes with pets.
  • Opt for the Roomba 694 if you’re on a budget and need a simple, effective vacuum for light cleaning in smaller spaces.

Ultimately, both models offer great value for money, but the i4 provides a more advanced cleaning experience, while the 694 offers excellent performance for everyday cleaning at a lower cost.
