The iRobot Roomba s9+ is recognized as a top-performing, highly autonomous robot vacuum, earning an Editors' Choice award for its powerful suction, effective corner-cleaning D-shape design, and self-emptying base. While offering exceptional navigation, the review notes significant drawbacks, including a high $1,399.99 price tag and shorter battery life compared to less expensive competitors.

The iRobot Roomba s9+ earns a 9/10 in the Wired review for its exceptional, methodical cleaning performance, featuring powerful suction, a corner-cleaning D-shaped design, and a reliable self-emptying Clean Base. While praised for its superior navigation and debris removal, the device is criticized for its high upfront cost and expensive, proprietary replacement bags.

The TechHive review characterizes the iRobot Roomba s9+ as a high-performance robot vacuum with a unique D-shaped design, 40 times the suction of the 600 series, and automatic disposal via the Clean Base. Its superior edge cleaning and robust performance on carpets are highlighted, though the device is described as very expensive, noisy, and limited by mediocre battery life on high power.

The Ambient designates the iRobot Roomba S9+ as a premium "gold standard" cleaner, praising its superb suction, self-emptying base, and advanced mapping, while noting its high price, noisy operation, and occasional mapping imprecision as primary drawbacks. This smart robot vacuum offers superior cleaning performance but still requires manual intervention for stairs.

The TechRadar review finds that the iRobot Roomba S9 Plus is an exceptionally powerful, premium, and autonomous vacuum featuring superior, efficient D-shaped corner cleaning and an easy-to-operate app, yet it is held back by a prohibitively high cost, inferior performance on carpets, and loud, high-decibel operation. Despite its excellent room mapping and automated self-emptying, it may struggle with fine dust on rugs and occasionally get caught, making it best suited for hard-floor-heavy homes.

The T3 review of the iRobot Roomba S9+ designates the device as a top-tier robot vacuum for its exceptional suction power, mapping capabilities, and efficient cleaning performance. Key pros highlighted include effective, wide rubber rollers, reliable home mapping, and the convenience of the Clean Base self-emptying system, though it is noted for its high cost and occasional issues with getting stuck on rugs.

The iRobot Roomba s9+ is described as a premium, high-performance robot vacuum featuring a D-shape design that excels at corner cleaning, alongside an advanced, high-suction 3-stage cleaning system and automatic dirt disposal. While offering superior navigation and smart mapping, the device’s drawbacks include a very high price tag, a tall, less compact dirt bin, and a lack of real-time object avoidance for small items.

The BGR review identifies the Roomba s9+ as the superior choice for deep-cleaning carpets and pet hair due to its exceptional suction and D-shaped design, though it lacks the advanced, real-time object avoidance found in newer, less-powerful models like the j7+. Key advantages of the s9+ include its 60-day auto-empty base and superior edge cleaning, while its disadvantages are a higher price and an older navigation system compared to the j7+.

Slinky Studio’s review of the iRobot Roomba s9+ praises its durable design, user-replaceable side brush, automatic dirt disposal, and 30% larger, high-performance dual rubber brushes for comprehensive cleaning. Key disadvantages noted include the raised lip of the copper top lid, which collects hair and dust, requiring occasional maintenance to clean the unit itself.
