iRobot Roomba j7+ vs. NARWAL Freo Z Ultra: A Detailed Comparison

## iRobot Roomba j7+ vs. NARWAL Freo Z Ultra: Detailed Comparison

Choosing the right robot vacuum cleaner can seem like a daunting task. The iRobot Roomba j7+ and NARWAL Freo Z Ultra are two popular candidates. They offer advanced features but fulfill different needs. Let’s compare them in detail to see which one is right for your home.

Performance

Roomba j7+ vacuum cleaner boasts excellent performance when cleaning hard floors and carpets thanks to its patented dual brush roll design. It is particularly effective at sucking up pet hair. On hard floors, however, it grinds up coffee grounds rather than sweeping them up.

The NARWAL Freo Z Ultra, on the other hand, does a great job with pet hair thanks to its zero-tangle roller brush. However, it falls short of the Roomba when it comes to deep cleaning carpets and hard floors. The Freo Z Ultra seems to focus more on surface cleaning than deep cleaning.

Cleaning Capabilities

When it comes to mopping, the Rumba j7+ features an innovative system with a metal lever that raises the mop to avoid carpets and an electric pump for mopping fluid. It does a good job with light soiling but can’t tackle stale, embedded dirt.

However, the NARWAL Freo Z Ultra shines with its superior cleaning capabilities. Its intelligent AI stain-sensing feature adjusts the cleaning process in real time to effectively remove dry spots and spills. The Freo Z Ultra also features a mop cleaning and drying station, which is a significant advantage over the Roomba.

Obstacle Avoidance and Navigation

Both robots have advanced obstacle avoidance systems, but they work differently. Roomba j7+ uses its front-facing camera and artificial intelligence to identify and avoid obstacles such as cables and shoes. Not bad overall, but it can still bump into furniture or snag on odd objects.

The NARWAL Freo Z Ultra has an outstanding obstacle avoidance system, using dual cameras and a chip to pinpoint and avoid objects. However, its navigation is inconsistent, sometimes pausing and making unnecessary turns. Mapping on the Roomba can be a bit clunky, with awkward movements during initial mapping, while map updates on the Freo Z Ultra can be slow.

Automatic Emptying and Maintenance

Rumba j7+ features an automatically emptying bin (clean base) that holds up to 60 days worth of waste. The base is compact and aesthetically pleasing, even accommodating a spare dust bag. However, it is quite noisy when emptied.

The NARWAL Freo Z Ultra has an advanced automatic emptying station with dust bag, cleaning and mop drying functions. This is a great advantage, but the logic behind the automatic emptying system can be confusing because the frequency of emptying is not the same. In addition, Roomba cleaning equipment requires more frequent maintenance due to the possibility of moisture getting into the brush roll housing.

App and User Experience

The Roomba j7+ app is user-friendly and allows you to set schedules, create restricted areas and customize cleaning settings. It also supports voice commands. However, it’s not perfect: sometimes it gets stuck for no reason or won’t return to the dock.

The NARWAL Freo Z Ultra app is also user-friendly, with advanced features like multi-level maps, schedule management, and 3D maps. However, the app can sometimes be too detailed and map updates can be slow.

Pros and Cons of iRobot Roomba j7+

Pros:

• Patented dual brush roll design for excellent vacuuming performance on both hard floors and carpets.
• Auto-emptying bin (clean base) is well designed and can hold up to 60 days of debris, reducing the need for maintenance.
• Advanced collision avoidance system with front camera and headlights and continuously updated software.
• Innovative cleaning system with a metal lever that raises the mop head to avoid carpeting and an electric pump for cleaning fluid.
• Easy to navigate features such as no-go zones, room-specific cleaning schedules, and indoor zone selection.
• This robot is quieter than many competing products and is suitable for home use.

Disadvantages of iRobot Roomba j7+:

• Hardware cleaning reduces navigation efficiency, resulting in increased cleaning time compared to competitors.
• Water can enter the brush roll housing during cleaning, causing debris buildup, requiring more frequent maintenance.
• The robot’s mapping is clunky and less satisfactory than other options.
• The front camera handles obstacle avoidance well, but may not keep the robot intelligent during mapping.
• Despite the improved obstacle avoidance, the robot can still get stuck on some odd objects.
• The robot sometimes does not return to base or complete cleaning tasks.

Pros and Cons of NARWAL Freo Z Ultra

Pros:

• Excellent obstacle avoidance system, accurately detects and avoids objects.
• Advanced automatic emptying station with dust bag, mop washing and drying functions.
• Superior mop capability, effectively removes dried dirt and spills.
• Intelligent Artificial Intelligence, adjusts cleaning to different stains in real time.
• Tangle-free brush roll catches even pet hair.
• User-friendly app with advanced features such as multi-level map, scheduling and 3D mapping.

Cons:

• Deep carpet cleaning performance is below average, can’t handle deeply embedded debris.
• Inconsistent navigation patterns.
• Automatic emptying system logic can be confusing due to inconsistent emptying frequency.
• Hard floor cleaning performance below average compared to previous model.
• Side skirting board cleaning module sometimes scuffs up dirt on furniture.
• Maps may update slowly and may behave unexpectedly when moving carpets.
