iRobot Roomba s9+ Review 2026: Is It Still Worth It?

Hook & Quick Verdict

The iRobot Roomba s9+ is a flagship robot vacuum that aims to do two things very well: deep cleaning (especially pet hair and fine debris) and hands-off convenience via the Clean Base automatic dirt disposal. Aggregating about 21,650 user reviews and scores from Amazon, Reddit, YouTube and expert blogs, the consensus is clear: the s9+ is one of the strongest cleaning performers on the market in 2026, but it’s also an expensive, maintenance-minded choice. Overall rating: 4.3/5 (quality 4.5, reliability 4.0, value 3.3, ease of use 4.6).

If you want top-tier suction and best-in-class edge pickup and don’t mind the higher upfront and ongoing costs, the s9+ remains a top pick. If you’re budget conscious or want the lowest-maintenance solution, look elsewhere.

What Is the iRobot Roomba s9+?

The Roomba s9+ is iRobot’s premium robot vacuum that pairs a D-shaped cleaning head (optimized for edges and corners) with a high-suction motor and the Clean Base self-emptying dock. It combines systematic LiDAR-style mapping and Imprint Smart Maps for room-level control, zone cleaning, scheduled routines, and multi-floor support. The s9+ is designed primarily for hard floors and low–medium pile carpets and is widely recommended for homes with pets because of its ability to pick up hair and fine debris.

Key hardware & software highlights

• D-shaped body for focused edge cleaning along baseboards and corners.
• High-suction motor and rubber multi-surface brushes to reduce tangles.
• Clean Base automatic dirt disposal that holds several weeks of debris in replaceable bags.
• Imprint Smart Maps for reliable mapping, no-go lines, and room-based commands.
• App control plus Alexa and Google Assistant voice integration.

What Reviewers Across the Internet Say

We synthesized reviews from four major sources to create a balanced picture.

• Amazon (4.3/5, generally positive): Buyers regularly praise the s9+ for suction power, edge cleaning, and the convenience of the self-emptying base. Positive reviews frequently come from pet owners and households with lots of hard-floor debris. Negative Amazon feedback centers on the product’s high price and occasional DOA or early-failure units; some buyers also reported frustrating warranty or service interactions.

• Reddit (3.8/5, mixed): Community threads are pragmatic. Enthusiasts confirm the cleaning capability but emphasize day-to-day maintenance: brush care, replacement-bag costs, firmware quirks, and intermittent reliability issues reported over longer ownership periods. Redditors are more likely to discuss real-world long-term trade-offs rather than first-impression performance.

• YouTube (4.4/5, positive): Video reviewers and comparative tests show measurable cleaning advantages—especially along edges—and demonstrate the mapping features. Reviewers call the s9+ a flagship model but repeatedly note noise during empty cycles, the high price, and the need to see long-term durability.

• Expert blogs (4.5/5, positive): Professional reviewers highlight the engineering: suction, edge design, and mapping quality. Experts tend to rate the s9+ among the best-performing consumer robot vacuums, while criticizing the premium price and the ongoing cost of consumables.

Taken together: performance and feature set are excellent; value and long-term cost are the main sticking points.

Performance & Real-World Use

Cleaning power: The s9+ consistently outperforms many competitors in suction-focused tasks. Users report excellent pickup of pet hair, cereal, coffee grounds and fine dust on hard floors and good results on low-pile carpets. The D-shaped front and side brush placement noticeably improve baseboard and corner cleaning compared with round robots.

Navigation & mapping: Imprint Smart Maps give predictable, repeatable room mapping and support zone cleaning, no-go lines, and multi-floor profiles. Most users find the mapping reliable out of the box; however, a minority of owners report occasional map drift, phantom obstacles, or the need to re-map after firmware updates.

Clean Base convenience (and trade-offs): The Clean Base is the strongest convenience feature—automatic emptying for weeks at a time reduces hands-on maintenance. But it introduces recurring costs (disposable bags) and extra mechanical points that can jam or fail. Users also report the auto-emptying cycle is loud and can be disruptive if located near living spaces.

Maintenance & longevity: To keep performance high, plan on regular brush cleaning (hair removal from the main brush and counter-rotating extractors), filter replacement, and periodic sensor cleaning. Community reviewers note that over years, replacement parts and bag costs add up—so the total cost of ownership is meaningfully higher than the sticker price.

Noise & household impact: The s9+ is louder during cleaning than many budget robots and particularly loud during auto-empty cycles. If you work from home or need quiet overnight operation, this matters.

Real-world tips from aggregated users

• Schedule emptying or runs while you’re out of the house if the Clean Base emptying noise is an issue.
• Keep a small toolkit and routine for brush and roller maintenance—these tasks materially preserve suction and performance.
• Buy replacement bags in multi-packs or consider third-party bag options where available, but weigh warranty and quality trade-offs.

Pros and Cons

Pros

• Industry-leading suction and excellent pickup of pet hair and fine debris.
• D-shaped design and focused edge-cleaning outperform many round robots along baseboards and corners.
• Clean Base auto-emptying provides real hands-off convenience for weeks of use.
• Robust mapping (Imprint Smart Maps) with room control, no-go lines and multi-floor support.
• Easy-to-use app and reliable voice assistant integration; systematic navigation yields efficient, repeatable cleaning.

Cons

• High upfront cost and lower perceived value (value score 3.3/5).
• Ongoing expense for Clean Base bags, filters, and replacement parts increases total cost of ownership.
• Some users report occasional reliability and software glitches (base jams, map errors) over long-term ownership.
• Emptying cycle is loud; overall operation is noisier than many competing models.
• Brushes can tangle with pet hair—regular maintenance is required to sustain performance.

Who Should Buy It (and Who Shouldn't)

Should buy if:

• You have pets or heavy hair/dust load and want the best possible pickup on hard floors and low-pile carpets.
• You value hands-off convenience and will pay for a self-emptying solution to reduce weekly chores.
• You want advanced mapping and room-level control for scheduled, targeted cleaning.

Shouldn't buy if:

• You’re price-sensitive or dislike recurring consumable costs; cheaper models offer good cleaning at a lower lifetime cost.
• You need a whisper-quiet machine for shared living spaces—emptying and run noise can be disruptive.
• You want a truly maintenance-free device—expect to perform routine brush and filter care.

Final Notes

The Roomba s9+ remains one of the strongest performers on the market in 2026 for households that prioritize suction, edge cleaning, and the convenience of automatic dirt disposal. Its strength is real-world cleaning, especially for pet owners, and its weaknesses are primarily cost and maintenance.
