Design & Build Quality

The Eureka J15 Max Ultra presents a sturdy, rounded‑square chassis that balances sleek modern styling with functional robustness. Its matte finish feels premium under the hand, while the Flex‑Arm Design allows the dual spinning mop pads to extend into corners for edge‑to‑edge cleaning—eliminating stubborn grime where other vacuums miss. At 9.3 inches in diameter and 3.6 inches tall, it navigates under low furniture yet houses an advanced IR‑vision sensor array to detect spills in any lighting.

The build integrates rugged wheels capable of climbing thresholds up to 40 mm, uncommon in this price tier. Plastic components feel durable, with no creaks even when lifting the chassis to inspect the brush assembly. Eureka’s FlexiRazor anti‑tangle technology is built into the central brush, with internal razors that continuously trim hair wraps, reducing maintenance downtime. The self‑emptying base station is similarly robust: a reinforced water reservoir, hot‑air drying vents, and a 75‑day debris bin.

Ergonomically, the top-mounted handle makes repositioning easy, and the low‑profile form factor ensures it won’t get stuck under most sofas. The overall impression is of a device designed not just to perform, but to endure daily household demands with minimal wear.

Navigation, Mapping & Sensors

At the core of the Eureka J15 Max Ultra is IntelliView AI 2.0, which fuses LiDAR mapping with infrared and RGB vision to build a 3D model of your home. Unlike earlier models that struggled with clear liquids, the J15 Max Ultra’s IR vision accurately detects both colored and transparent spills, automatically raising its brush to avoid damage and rotating to mop the area.

Mapping is swift: initial room scans complete in under three minutes, generating precise floor plans accessible in the mobile app. Virtual no‑go zones and carpet‑boost areas can be drawn with finger‑drag accuracy. The robot even marks detected obstacles—pet bowls, cables, shoes—on the map, letting you track exactly what it encountered.

Obstacle avoidance is best‑in‑class. The combination of depth‑sensing IR and LiDAR means the J15 Max Ultra rarely bumps furniture; instead, it slows and navigates gently around legs and low obstacles. In dim light or total darkness, cleaning continues unhindered—an advantage of infrared vision over camera‑only systems.

Finally, the threshold‑climbing ability (up to 40 mm) ensures smooth transitions between rooms, even over thick rugs or slight elevation changes. This robust sensor suite and navigation logic deliver a near‑human level of spatial awareness.

Performance & Cleaning Power

When it comes to raw suction, the Eureka J15 Max Ultra raises the bar with a peak 22,000 Pa motorized punch—over 30% stronger than its predecessor. In tests on hardwood, low‑pile carpet, and rugs, it lifted dust, cereal, and pet hair in one pass more consistently than average competitors.

The multi‑stage filtration captures 99.7% of particles down to 0.3 microns, making it a solid pick for allergy sufferers. During week‑long trials in a dual‑pet household, the J15 Max Ultra maintained peak performance with barely any loss in suction—courtesy of the self‑cleaning base that automatically clears hair and debris from the brush roll.

Its dual spinning mop pads, driven by ScrubExtend Technology, exert adjustable pressure—up to 3 psi—to scrub dried‑on stains. Though not a substitute for manual deep‑scrubbing, it significantly outperforms most robot mops on dried spills. The trade‑off is speed: a combined vacuum‑and‑mop run can take upwards of 120 minutes for a 2,000 ft² space, but the spotless result is worth it for many.

Noise levels measure 58–68 dB depending on suction setting—noticeable but comparable to a dishwasher. In Quiet mode, cleaning continues at 12,000 Pa with minimal disturbance. Overall, this model sits at the top of its class for cleaning efficacy.

Wet‑Mess Handling & Mopping

The standout of the Eureka J15 Max Ultra is its liquid‑spill intelligence. Most robot vacuums smear puddles, but the J15 Max Ultra’s infrared vision discerns liquid depth and composition, prompting it to switch to mopping mode and raise the brush deck.

Its dual mop pads, driven by ScrubExtend Technology, extend into corners and apply consistent scrubbing motion. The base station automatically drains dirty water, refills the onboard tank with fresh cleaning solution, and uses hot‑air drying to prevent mildew. Unlike legacy models requiring manual mop maintenance after each wet run, the J15 Max Ultra can handle up to 75 days of mopping cycles without intervention.

This capability transforms robot vacuums from a dry‑debris tool into a true wet‑dry cleaner—ideal for families with kids or pets. It even offers a Pre‑Soak mode, where it wets the floor first, lets the solution dwell for two minutes to loosen grime, then scrubs and suctions. This three‑step process yields a noticeably deeper clean.

While not replacing a full wet‑vac for large floods, its performance on everyday spills is unmatched. If your priority is accident‑proof floor care, the Eureka J15 Max Ultra sets a new standard.

Battery Life & Charging Base

Equipped with a 5,200 mAh Li‑ion battery, the Eureka J15 Max Ultra delivers up to 120 minutes of continuous cleaning on quiet mode and around 75 minutes at maximum suction.

When battery dips below 20%, it auto‑docks, recharges to 80% in 30 minutes, then resumes cleaning—a feature known as smart resume. The self‑emptying base holds 75 days of dust and debris and includes a hot‑air drying function to keep mop pads hygienic. Water drainage from the mop reservoir is handled automatically, so no manual emptying is needed even after extensive mopping sessions.

The charging station’s LED indicators show bin status, water levels, and filter health. A built‑in UV‑LED lamp in the base offers optional sterilization for mop pads, reducing bacterial growth over time. Overall, the combination of long runtimes and an autonomous base makes the J15 Max Ultra genuinely low‑maintenance.

Connectivity & App Features

The Eureka Home app (iOS & Android) offers comprehensive control over the Eureka J15 Max Ultra. In addition to viewing real‑time camera feeds, users can set multi‑level maps, define virtual barriers, and schedule zone‑specific cleans.

Carpet‑boost, mop intensity, and suction power are all adjustable per room, with presets for hardwood, tile, and carpet. Live video streaming works as a pet camera, with 1080p resolution and night vision—handy for checking on pets or children.

The app also logs cleaning history, with area‑cleaned, time‑spent, and maintenance alerts. Integration with Alexa and Google Assistant allows voice‑activated cleaning commands (“Hey Alexa, tell Eureka to clean the kitchen”). IFTTT support enables custom automations—e.g., start cleaning when you leave home.

Firmware updates download and install automatically via Wi‑Fi, ensuring the robot benefits from the latest navigation and spill‑detection enhancements. Overall, the app experience feels mature and feature‑rich, on par with top‑tier competitors.
