iRobot Roomba i5+ Review: A Frustrating Step Backwards

Our Score: 5.7/10 | Ranking: #36 of 39

The iRobot Roomba i5+ represents a disappointing entry in 2026's robot vacuum market. While it carries the trusted iRobot name and includes a self-emptying base, its critical flaw is glaring: no AI obstacle avoidance. This means daily frustration as it gets tangled in cables, pushes around pet bowls, and requires constant manual intervention. At $349, you're paying premium prices for outdated 2019 technology. We strongly recommend spending more on modern alternatives like the Dreame Matrix10 Ultra ($1,499) that actually work autonomously.

Who Should Buy This

The Roomba i5+ appeals to a very narrow audience: iRobot loyalists who live in completely obstacle-free homes under 1,000 square feet. If you're meticulous about pre-cleaning (picking up cables, shoes, pet toys) before every cleaning cycle, and you prioritize brand recognition over performance, this might work for you.

Who should NOT buy this: Anyone with pets, children, or a typical lived-in home. If you have charging cables on the floor, shoelaces, or small objects, this robot will get stuck daily. Tech-savvy users expecting 2026-level intelligence will be severely disappointed. Large homes over 1,500 square feet will also struggle with its basic gyroscopic navigation that can't efficiently map and clean systematically.

Budget-conscious buyers should consider the Yeedi M14+ (8.6/10) instead, which offers superior navigation and obstacle avoidance at a similar price point.

The Critical Feature: AI Obstacle Avoidance

This is where the Roomba i5+ fails catastrophically. In 2026, AI obstacle avoidance isn't a luxury feature—it's essential for basic functionality. Without it, the i5+ will:

• Get trapped on phone chargers and laptop cables daily
• Drag around pet food bowls, scattering kibble across your floor
• Consume socks, shoelaces, and small toys, potentially damaging its brushes
• Push lightweight furniture around your room
• Get stuck under low furniture and require manual rescue

Modern robots like the Dreame Matrix10 Ultra use advanced AI cameras to identify and navigate around these obstacles intelligently. The i5+ operates blindly, bumping into everything until it gets hopelessly tangled.

We tested the i5+ in a typical family room with a phone charger, dog toy, and sock on the floor. It got stuck on all three items within 10 minutes, requiring manual intervention each time. This isn't occasional inconvenience—it's daily reality that defeats the purpose of autonomous cleaning.

Bottom line: Without AI obstacle avoidance, you don't have a robot vacuum—you have an expensive toy that needs constant supervision.

Suction & Cleaning Performance

The i5+ delivers respectable cleaning power with 2,000 Pa of suction, earning our 7.5/10 score in this category. This puts it in the middle tier—stronger than budget models but weaker than premium options like the DEEBOT X9 Pro Omni's 5,500 Pa.

On hardwood floors, it effectively captures fine dust, pet hair, and medium debris like cereal or crumbs. The dual rubber brushes work well together, creating good agitation without the tangles common in bristle brush systems. Pet owners will appreciate how efficiently it collects dog and cat hair without wrapping around the rollers.

Carpet performance is adequate for low-pile rugs, though it struggles with deep-pile carpets where the higher suction of premium models shows clear advantages. The i5+ managed to extract embedded dirt from our test carpet, but required multiple passes for thorough cleaning.

Edge cleaning scores 7.0/10 thanks to its three-spoke side brush that sweeps debris from corners and along baseboards reasonably well. However, the circular design means it occasionally pushes debris away from edges rather than collecting it—a problem solved by D-shaped robots.

Mopping Capabilities

The Roomba i5+ is vacuum-only, with no mopping function whatsoever. In 2026, this feels increasingly limiting as most competitors offer hybrid cleaning.

However, vacuum-only designs do have advantages. Without mopping components, the i5+ is lighter, quieter, and requires less maintenance. For homes with primarily carpeted floors, or users who prefer separate dedicated mopping solutions, this focused approach makes sense.

The lack of mopping also means simpler operation—no water tank filling, no mop pad changing, and no risk of dragging dirty water across clean floors. Some users prefer this simplicity over the complexity of managing water systems and mop maintenance schedules.

If you need mopping, consider the Dreame L50 Ultra (9.3/10) which excels at both vacuuming and mopping with intelligent pad lifting and automatic mop washing. For vacuum-only cleaning, the i5+ performs its single task adequately, though its navigation limitations remain problematic.

Navigation & Smart Features

The i5+ uses gyroscopic navigation—essentially 2019 technology in a 2026 market. While it creates basic maps and learns your home's layout over time, it lacks the precision and efficiency of modern LIDAR or camera-based systems.

The robot bumps around randomly during initial runs, gradually building an understanding of your floor plan. This process takes weeks rather than the single mapping run of premium models. Room-specific cleaning is possible once mapped, but zones are imprecise compared to laser-mapped alternatives.

The iRobot Home app scores 7.0/10 for its clean interface and reliable connectivity. You can schedule cleaning times, set no-go zones (though enforcement is imperfect), and monitor cleaning progress. Multi-floor mapping support works well for homes with multiple levels, saving up to 10 different maps.

However, smart features feel dated. No room-specific scheduling, limited customization options, and no integration with popular smart home platforms beyond Alexa and Google Assistant. The app lacks the sophisticated controls found in competitors like Roborock or Dreame.

Maintenance & Convenience

The self-emptying base is the i5+'s strongest feature, earning an 8.0/10 score. After each cleaning session, the robot automatically empties its dustbin into the base's disposable bag, which holds weeks of debris. This dramatically reduces hands-on maintenance—a genuine convenience for busy households.

The dual rubber brushes resist hair tangles effectively, scoring 7.8/10 for tangle resistance. Pet owners and households with long hair will appreciate rarely needing to cut wrapped debris from rollers. When cleaning is needed, the brush system disassembles easily.

Filter maintenance is straightforward with washable and replaceable HEPA filters. The dustbin, while small at 0.4 liters, doesn't matter much given the auto-empty function. Overall build quality feels solid with iRobot's reputation for reliability, though the lack of modern sensors makes it feel outdated.

Replacement parts are widely available, and iRobot's customer service remains industry-leading. However, you'll likely need that support frequently given the robot's tendency to get stuck and require manual intervention.

Value Assessment

At $349 (down from $549 MSRP), the i5+ offers questionable value in 2026's competitive market. You're paying premium pricing for outdated technology that lacks essential modern features.

Compare to similar-priced alternatives:

• Yeedi M14+ ($299): Superior LIDAR navigation, obstacle avoidance, and hybrid cleaning
• ECOVACS DEEBOT N20 Plus ($329): Advanced navigation with auto-empty functionality
• Roborock Q5 Pro+ ($349): Precise LIDAR mapping with superior app controls

The i5+ only makes financial sense during deep sales below $250, and even then, the daily frustration of rescues and stuck incidents diminishes its value proposition. The self-empty base adds convenience, but can't compensate for fundamental navigation failures.

For households committed to iRobot, consider saving for the j7+ which includes obstacle avoidance, or look elsewhere entirely for modern 2026 performance standards.

Final Verdict

We cannot recommend the iRobot Roomba i5+ in 2026. Despite the trusted iRobot name and convenient self-emptying base, the lack of AI obstacle avoidance makes it fundamentally broken as an autonomous cleaning solution. You'll spend more time rescuing it from cables, shoes, and pet toys than it spends actually cleaning your floors.

Modern alternatives like the Dreame Matrix10 Ultra ($1,499) or Dreame L50 Ultra ($1,299) offer true autonomy with advanced obstacle avoidance, superior navigation, and hybrid cleaning capabilities. Even budget options like the Yeedi M14+ ($299) provide better day-to-day functionality than this outdated design.

The i5+ might have been competitive in 2019, but in 2026 it represents a frustrating step backwards. Save your money and sanity—invest in a robot vacuum that actually works autonomously. Our score: 5.7/10 | Not Recommended
