My Journey With Robot Vacuums

As someone who’s juggled work, family, and a shedding golden retriever, I was tired of dragging out my heavy upright vacuum every few days. The idea of a robot vacuum that could clean my floors while I sipped coffee sounded like a dream. After researching iRobot’s lineup, I zeroed in on the Roomba i5 and j7, two models that seemed to balance affordability and advanced tech. I tested both in my 1,500-square-foot home with a mix of hardwood, tile, and carpets, plus plenty of pet hair and kid-related messes. Here’s what I found.

Roomba i5: The Budget-Friendly Workhorse

The Roomba i5, particularly the Combo i5+ model I tested, is iRobot’s mid-range offering, designed for folks who want solid cleaning without breaking the bank. Released in August 2023, it’s a versatile vacuum that can mop with the right setup, and its self-emptying dock (in the i5+ version) makes maintenance a breeze. I was impressed by its straightforward approach to cleaning, but it’s not without limitations.

Key Features of the Roomba i5

The i5 uses iRobot’s iAdapt 1.0 SLAM navigation, which relies on sensors to map your home. It moves in neat rows, unlike older Roombas that bounced around randomly. In my home, it created a single map that I could label for specific rooms, like “kitchen” or “living room,” through the iRobot HOME app. This allowed me to send it to clean just the dining area after my kids turned it into a crumb warzone.

The suction power, rated at 10 times that of iRobot’s 600 Series, handled pet hair and cereal bits on my hardwood floors well. The dual rubber brushrolls—a signature Roomba feature—did a decent job on my low-pile carpets, though they struggled with deeply embedded dirt. The Combo i5+ model I tested required swapping the dustbin for a mopping bin, which was a bit of a hassle but worked fine for light mopping on my kitchen tiles.

The self-emptying dock was a game-changer. After each cleaning session, the i5+ empties its onboard bin into a disposable bag that holds up to 60 days of debris. I didn’t have to touch dust or pet hair for weeks, which was a relief for my allergies. The i5 also integrates with Alexa and Google Assistant, so I could start it with a simple “Alexa, tell Roomba to clean the living room.”

Pros of the Roomba i5

• Affordable Price: At $349-$399, it’s a budget-friendly option for a smart vacuum with self-emptying capabilities.
• Solid Cleaning Performance: The 10x suction power and dual brushrolls handle everyday messes like pet hair and crumbs effectively.
• Smart Mapping: Creates a single map for room-specific cleaning, perfect for small to medium homes.
• Self-Emptying Dock (i5+): Reduces maintenance by emptying the bin for up to 60 days.
• Voice Control: Works seamlessly with Alexa and Google Assistant for hands-free operation.

Cons of the Roomba i5

• Basic Navigation: Lacks a camera, so it can bump into furniture or get stuck on cords.
• No Obstacle Avoidance: Doesn’t detect small objects like pet waste, which can lead to messy accidents.
• Manual Mopping Swap: The Combo model requires swapping bins to mop, which feels clunky.
• Limited Map Storage: Only stores one map, not ideal for multi-level homes.
• Light Mopping: The mopping feature is basic and struggles with tough stains.

Roomba j7: The Smart Navigator

The Roomba j7, particularly the Combo j7+ model, is iRobot’s premium mid-range vacuum, launched in 2021. It’s pricier at $599-$649 but packs advanced features like AI-powered obstacle avoidance and a retractable mopping system. Testing it in my home, I noticed it was smarter and more autonomous than the i5, making it a better fit for cluttered or pet-heavy households.

Key Features of the Roomba j7

The j7’s standout feature is its PrecisionVision navigation, which uses a front-facing camera and AI to identify and avoid obstacles like cords, toys, and—crucially—pet waste. iRobot’s Pet Owner Official Promise (P.O.O.P.) guarantees a replacement if the j7 runs over pet messes, which gave me peace of mind with my puppy-prone-to-accidents. In my tests, the j7 deftly avoided a charging cable and a stray sock, unlike the i5, which got tangled.

Like the i5, the j7 has 10x suction power and dual rubber brushrolls, performing equally well on hardwood and carpets. However, its mopping system is a step up. The Combo j7+ has a retractable mopping pad that lifts when it detects carpets, ensuring they stay dry. I didn’t need to swap bins, which made mopping my kitchen and bathroom floors seamless.

The j7 can store up to 10 maps, ideal for multi-level homes. I set up maps for my main floor and basement, directing it to clean specific areas via the app. The self-emptying dock, like the i5+’s, holds 60 days of debris, and voice control worked flawlessly. The j7 also uses geofencing to clean when I’m away, minimizing noise disruptions.

Pros of the Roomba j7

• Advanced Obstacle Avoidance: AI and camera-based navigation avoid cords, toys, and pet waste, reducing mishaps.
• Retractable Mopping System: The Combo j7+ automatically lifts its mop on carpets, making it hassle-free.
• Multiple Map Storage: Stores up to 10 maps, perfect for larger or multi-level homes.
• Self-Emptying Dock (j7+): Empties debris for up to 60 days, minimizing maintenance.
• Smart Features: Geofencing and app-based controls offer a highly customized cleaning experience.

Cons of the Roomba j7

• Higher Price: At $599-$649, it’s significantly more expensive than the i5.
• No Auto-Wash Dock: Mopping pads need manual cleaning, unlike some competitors.
• Similar Suction Power: Matches the i5’s suction, so no advantage in raw cleaning power.
• Occasional Software Glitches: Some users report navigation issues in low-light conditions.
• Mopping Limitations: Doesn’t apply downward pressure, so it’s less effective on stubborn stains.

Performance in Real-World Scenarios

To get a true sense of how these Roombas perform, I put them through their paces in my home. My living room, with its mix of hardwood and area rugs, was the primary testing ground. The i5 handled pet hair and dust well, but it occasionally bumped into chair legs and got stuck on a rug fringe. The j7, with its camera, navigated around furniture more gracefully and never got tangled.

In the kitchen, where spills and crumbs are common, both Roombas did a solid job vacuuming. The i5’s mopping required me to swap bins and fill the water tank, which was a minor annoyance. The j7’s retractable mop was a game-changer—it switched between vacuuming and mopping without my intervention, keeping my rugs dry.

Pet owners will appreciate the j7’s obstacle avoidance. When my puppy left a “surprise” on the floor, the i5 smeared it (my fault for not cleaning it up first), while the j7 avoided it entirely. The j7’s P.O.O.P. guarantee adds confidence, but I was relieved it didn’t come to that.

For larger homes, the j7’s ability to store multiple maps is a big plus. I could send it to clean my basement without re-mapping, while the i5 required me to reset its map when I moved it downstairs. Both models’ 75-minute battery life was sufficient for my 1,500-square-foot main floor, but they needed to recharge mid-cycle for larger areas.

Maintenance Tips

Maintaining a Roomba keeps it running smoothly, and I learned a few tricks while testing the i5 and j7.

• Clean the Brushrolls Regularly: Both models’ dual rubber brushrolls collect hair, so remove and clean them weekly to prevent clogs.
• Empty the Mopping Bin (Combo Models): For the i5, empty and rinse the mopping bin after each use; for the j7, wash the mopping pad to avoid odors.
• Check the Sensors: Wipe the i5’s sensors and j7’s camera lens with a dry cloth to ensure accurate navigation.
• Replace Filters and Bags: Use high-efficiency filters and replace them every 2-3 months; self-emptying dock bags last about 60 days.
• Update the App: Keep the iRobot HOME app updated to avoid software glitches and access new features.

Comparison with Other Brands

To put the i5 and j7 in context, I compared them to similar models from competitors like Roborock and Eufy.

• Roborock S7 MaxV Ultra: Offers superior mopping with vibration technology and an auto-wash dock, but it’s pricier than both Roombas.
• Eufy RoboVac G30: Cheaper than the i5 but lacks smart mapping and self-emptying, making it less convenient.
• Shark AI Ultra: Matches the j7’s obstacle avoidance but has a less reliable mopping system and shorter battery life.
• Dyson 360 Vis Nav: Excellent suction but lacks mopping and is significantly more expensive than the j7.

Which Roomba Suits Your Home?

Choosing between the i5 and j7 depends on your budget, home size, and cleaning needs. If you live in a small apartment with minimal clutter and don’t mind manual mopping, the i5 (or i5+) is a cost-effective choice. Its smart mapping and self-emptying dock make it a step above basic robot vacuums, and it handles everyday messes well.

For pet owners, larger homes, or cluttered spaces, the j7 (or j7+) is worth the extra cost. Its obstacle avoidance, retractable mopping system, and multi-map storage make it more autonomous and versatile. The P.O.O.P. guarantee is a nice bonus for pet owners like me who’ve dealt with unexpected messes.

My Personal Verdict

After weeks of testing, I lean toward the Roomba j7+. Its smarter navigation and hassle-free mopping system saved me time and stress, especially with a puppy and kids creating chaos. The i5 is a solid performer for the price, but its limitations—like basic navigation and manual bin swapping—make it less ideal for complex households. If your budget allows, the j7’s advanced features make it a better long-term investment.
