A Brief Comparison Table

My Journey With The Roomba j6 And j7

I’ve always been a fan of robot vacuums.

They’re like little helpers that save me from the daily grind of sweeping up dog hair and stray Cheerios.

When I got my hands on the Roomba j6 and j7, I was excited to see how these two models stacked up.

Both are part of iRobot’s premium lineup, promising smart navigation, powerful cleaning, and pet-friendly features.

But as I put them through their paces in my 1,200-square-foot home with two dogs and a toddler, I quickly noticed differences that could sway your decision.

The j6 and j7 share a lot of DNA, but they’re not twins. The j7 boasts advanced obstacle avoidance, while the j6 is often a better deal price-wise.

I’ll walk you through their key features, share my real-world observations, and break down the pros and cons to help you figure out which one deserves a spot in your home.

Key Features of The Roomba j6

The Roomba j6 (and its self-emptying j6+ variant) is a solid contender in iRobot’s lineup. It’s designed for homes with pets, kids, or anyone who wants a reliable vacuum without breaking the bank. Here’s what stood out during my testing:

• Navigation and Mapping

The j6 uses iRobot’s iAdapt 3.0 with vSLAM (visual simultaneous localization and mapping). It relies on a camera and sensors to map your home, creating a digital layout you can view in the iRobot Home app.

After a few runs, it learned my home’s floor plan, letting me send it to specific rooms like the kitchen or living room. It’s not perfect—it occasionally bumped into chair legs—but it rarely got stuck.

• Cleaning Performance

With suction power rated at 10 times that of iRobot’s 600-series, the j6 handled my hardwood floors and low-pile carpets well. It picked up dog hair, dust, and small debris like cereal without issue.

The dual rubber brushrolls and edge-sweeping brush did a decent job, though I noticed some pet hair tangled around the brushes after a week of use.

• Obstacle Avoidance

The j6’s obstacle avoidance is basic but effective for pet owners. It’s programmed to dodge cords and pet waste, backed by iRobot’s P.O.O.P. (Pet Owner Official Promise) guarantee, which promises a replacement if the vacuum runs over pet messes.

In my tests, it steered clear of a charging cable and a (fake) pet mess I placed for science. However, it didn’t always spot smaller items like socks or toys.

• Smart Features

The j6 integrates with the iRobot Home app, where you can schedule cleanings, set no-go zones, and monitor cleaning history. It also works with Alexa and Google Assistant, so I could say, “Alexa, tell Roomba to clean the kitchen,” and it obeyed.

The app’s interface is intuitive, and I loved the ability to name rooms for targeted cleaning.

• Self-Emptying (j6+)

The j6+ comes with a self-emptying Clean Base that holds up to 60 days of debris. Emptying the base was a breeze—just pop out the bag and toss it. The non-plus j6 requires manual emptying, which got old fast in my busy household.

• Design and Battery

At 13.3 inches wide and 3.4 inches tall, the j6 slips under most furniture. Its 120-minute battery life was enough to clean my downstairs in one go, though it occasionally needed to recharge before finishing larger jobs.

The recharge-and-resume feature ensured it picked up where it left off.

Key Features of The Roomba j7

The Roomba j7 (and j7+ with self-emptying) is a step up, with a focus on smarter navigation and versatility. Here’s what I found during my tests:

• Navigation and Mapping

The j7’s PrecisionVision Navigation is a game-changer. Its front-facing camera is more advanced than the j6’s, allowing it to identify and avoid a wider range of obstacles. It mapped my home just as well as the j6, but it was noticeably better at navigating tight spaces and avoiding clutter.

I could see the map evolve in the app, with options to set keep-out zones or clean specific areas.

• Cleaning Performance

The j7’s suction power matches the j6’s on paper (10x the 600-series), but in my tests, it edged out slightly, picking up 9.8 CFM of debris compared to the j6’s 7.27 CFM. It tackled pet hair, dust, and even ground-in dirt on my carpets with ease.

The dual rubber brushrolls were less prone to tangling than older Roomba models, though I still had to clean them occasionally.

• Obstacle Avoidance

The j7’s obstacle avoidance is where it shines. It’s programmed to dodge not just cords and pet waste but also socks, shoes, towels, and even pet bowls. In my home, it navigated around my toddler’s scattered toys and my dog’s water bowl without a hitch.

It even sent me photos of obstacles via the app, letting me decide whether to avoid them in the future. This feature made the j7 feel like a smarter, more autonomous cleaner.

• Smart Features

Like the j6, the j7 works with the iRobot Home app and voice assistants. The app experience is identical, with scheduling, room-specific cleaning, and cleaning history tracking.

The j7 also supports geofencing, so it can clean when you’re away and pause if you return home. This was handy when I forgot to start it before leaving for work.

• Self-Emptying (j7+)

The j7+’s Clean Base is the same as the j6+’s, holding 60 days of debris. It’s a lifesaver for hands-off maintenance. The standard j7, like the j6, requires manual emptying, which I found tedious after a few runs.

• Mopping (j7+ Combo)

Unlike the j6, the j7+ Combo model adds mopping with a retractable mopping pad. When it detects carpet, it lifts the pad to avoid wetting it. I tested the Combo version, and it did a decent job on my hardwood floors, though it struggled with tough stains like dried juice.

The j6 lacks this feature but can sync with the Braava m6 mop for sequential cleaning.

• Design and Battery

The j7’s design mirrors the j6’s—13.3 inches wide, 3.4 inches tall, and 7.35 pounds (slightly lighter than the j6’s 7.49 pounds). Its 120-minute battery life matched the j6’s, with recharge-and-resume ensuring no job went unfinished.

Pros And Cons of Roomba j6

Pros

• Affordable Price Point: The j6 and j6+ are often hundreds of dollars cheaper than the j7, especially during sales (I snagged a j6+ for $399.99 on Amazon).
• Solid Cleaning Performance: It handles pet hair, dust, and small debris well on hard floors and low-pile carpets.
• Smart Mapping: Imprint Smart Mapping lets you target specific rooms and set no-go zones.
• P.O.O.P. Guarantee: Peace of mind for pet owners.
• Self-Emptying (j6+): The Clean Base reduces maintenance to once every two months.
• Voice Control: Seamless integration with Alexa and Google Assistant.

Cons

• Basic Obstacle Avoidance: It only avoids cords and pet waste, often bumping into socks or toys.
• No Mopping: You’ll need a separate Braava m6 for mopping, adding cost.
• Tangle-Prone Brushes: Pet hair occasionally wrapped around the brushrolls, requiring manual cleaning.
• Slightly Weaker Suction: It lagged behind the j7 in deep-cleaning tests, especially on carpets.

Pros And Cons of Roomba j7

Pros

• Advanced Obstacle Avoidance: Detects and avoids a wide range of objects, making it ideal for cluttered homes.
• Stronger Cleaning Performance: Slightly better suction (9.8 CFM vs. 7.27 CFM) for tougher messes.
• Mopping Option (j7+ Combo): The retractable mopping pad adds versatility for homes with mixed flooring.
• Smart Features: Geofencing and obstacle photo alerts enhance automation.
• Self-Emptying (j7+): Same convenient Clean Base as the j6+.
• P.O.O.P. Guarantee: A must for pet owners.

Cons

• Higher Price: The j7 and j7+ are pricier, with the j7+ often retailing for $799.99.
• Mopping Limitations: The j7+ Combo struggles with tough stains and requires manual pad washing.
• Occasional Hair Tangling: Like the j6, it’s not completely tangle-free.
• No Significant Battery Advantage: Identical 120-minute runtime as the j6.

My Real-World Testing Experience

To get a true sense of how the j6 and j7 perform, I set up a series of tests in my home. My living space is a mix of hardwood floors, low-pile rugs, and a high-traffic kitchen where my toddler loves to scatter crumbs.

Two dogs add a constant layer of fur, and random toys and cables are a daily reality.

• Test 1: Pet Hair and Debris

I scattered dog hair, Cheerios, and coffee grounds on my hardwood floor and low-pile rug. Both Roombas did well, but the j7 was noticeably better at picking up fine debris like coffee grounds, especially on the rug.

The j6 left a few stray pieces behind, requiring a second pass. On pet hair, both were effective, but I had to clean the j6’s brushes more often due to tangling.

• Test 2: Obstacle Avoidance

I set up an obstacle course with a charging cable, a sock, a toy car, and a (fake) pet mess. The j6 avoided the cable and pet mess but nudged the sock and toy before redirecting.

The j7, however, dodged everything flawlessly, even sending me a photo of the sock to confirm whether it should avoid it in the future. This made the j7 feel like a more hands-off option for my cluttered home.

• Test 3: Navigation and Mapping

Both Roombas mapped my home accurately after three runs, letting me send them to specific rooms via the app. The j7 was smoother in tight spaces, like around my dining table, while the j6 occasionally bumped into chair legs.

Neither got stuck, thanks to their cliff sensors, but the j7’s PrecisionVision made it more graceful.

• Test 4: Mopping (j7+ Combo)

Since the j6 doesn’t mop, I tested the j7+ Combo on my kitchen’s hardwood floor, where juice spills are a daily occurrence. It handled light dirt well but couldn’t fully remove a dried-on stain. I had to wash the mopping pad manually, which was a minor hassle.

If you have hard floors, the j7+ Combo is convenient, but don’t expect it to replace a traditional mop for tough messes.

• Test 5: Battery and Coverage

Both Roombas lasted about 110 minutes in my tests, covering my entire downstairs (about 1,000 square feet) before needing a recharge. The recharge-and-resume feature worked flawlessly, ensuring no area was missed.

For larger homes, this feature is a lifesaver.

Which Roomba Suits Your Home?

Choosing between the j6 and j7 depends on your budget, home size, and lifestyle. Here’s how they fit different scenarios:

If You Choose the Roomba j6

The j6 is perfect for budget-conscious buyers who want a reliable robot vacuum with smart features. It’s ideal for:

• Pet Owners on a Budget: The P.O.O.P. guarantee and solid pet hair performance make it great for homes with one or two pets.
• Small to Medium Homes: Its 120-minute battery life handles apartments or single-story homes well.
• Simple Layouts: If your home isn’t cluttered with toys or small objects, the j6’s basic obstacle avoidance is sufficient.

However, if you have thick carpets or need mopping, you’ll need to look elsewhere or pair the j6 with a Braava m6.

If You Choose the Roomba j7

The j7 is better for those willing to spend more for a smarter, more versatile vacuum. It’s ideal for:

• Cluttered Homes: Its advanced obstacle avoidance handles toys, socks, and cables with ease.
• Mixed Flooring: The j7+ Combo’s mopping feature is a bonus for homes with hardwood or tile alongside carpets.
• Hands-Off Cleaning: Features like geofencing and obstacle alerts make it feel more autonomous.

The j7’s higher price is the main drawback, but sales (like $529.99 for the j7+) can make it more affordable.

My Verdict After Living With Both

After weeks of testing, I lean toward the j7 for its smarter navigation and obstacle avoidance. In my busy home, the ability to dodge my toddler’s toys and my dog’s water bowl made the j7 feel like a true set-it-and-forget-it device.

The j7+ Combo’s mopping was a nice bonus, though it’s not a game-changer for heavy stains. That said, the j6 is no slouch. It’s a fantastic value, especially at sale prices, and its cleaning performance is nearly as good for simpler homes.

If money’s tight, the j6 or j6+ gets the job done. If you want the most polished experience and can stomach the cost, the j7 or j7+ is worth the splurge. Your choice depends on how much you value convenience versus cost.
