In-depth iRobot Roomba s9+ review

Independent editorial — no manufacturer input on scoring.

Overview

The iRobot Roomba s9+ is iRobot's 2019 entry in the self-empty vacuums space, positioned squarely at homes that want irobot's d-shape flagship with the strongest suction. At a current street price of $999 — down from a launch RRP of $1,299, it competes head-on with everything else on our self-empty vacuums shortlist. Over an average of 6,840 verified owner reviews it holds a 4.4-star rating, which puts it comfortably in the upper tier for the category. What makes it worth a closer look is the specific combination of d-shape for corner cleaning, 40x suction of roomba 600, perfectedge corner brush and clean base with sealed bag — a set of decisions that reflect iRobot's house style and set clear expectations for who this robot is (and is not) for.

Performance & cleaning

In day-to-day use the Roomba s9+ delivers on its headline specs: suction of Not published (highest in iRobot lineup), runtime of 120 minutes. Independent testing and long-term owner reports converge on the same story — class-leading edge and corner cleaning is consistently the standout, followed closely by excellent build quality. In practical terms that translates into predictable, quiet cleaning cycles that you can schedule and forget. The trade-off is that expensive, which some buyers will care about and others will happily ignore.

Navigation, mapping & smart features

iRobot equips the Roomba s9+ with vSLAM + Imprint, which handles the boring-but-critical job of getting the robot around your home efficiently. The companion iRobot Home exposes imprint smart mapping, anti-tangle rubber rollers and braava jet imprint link, which is standard for this class in 2019 but noticeably better than what you get on generic no-name alternatives. If you already own other iRobot products, the ecosystem integration is a genuine advantage — one app, one login, and consistent notification behaviour across the household.

Build quality & design

Physically the Roomba s9+ measures in line with class norms and weighs 4.1 kg. iRobot has clearly prioritised powerful suction for irobot in the industrial design — panels align cleanly, the buttons feel deliberate, and the accessible components (filters, brushes, tanks) are easy to remove without tools. The stated warranty of 1 year matches what serious iRobot buyers expect, and the after-sales support network is one of the reasons long-term owners keep coming back to iRobot even when cheaper Chinese alternatives spec higher on paper.

Maintenance & running costs

Ongoing costs for the Roomba s9+ are dominated by consumables — expect to replace brushes, filters and mop pads every 3–6 months. Budget roughly $60–$150 per year for a mid-range self-empty vacuums robot; the Roomba s9+ sits in the middle of that range. Cleaning the unit itself is a five-minute weekly job — clear brushes of hair, wipe sensors, empty bins. The iRobot app will remind you when consumables need attention, which sounds trivial until you've owned a robot without that feature.

Pros & cons at a glance

Reasons to buy: class-leading edge and corner cleaning, excellent build quality and powerful suction for irobot. Reasons to hesitate: expensive and older platform. Neither list is decisive on its own — the Roomba s9+ is a well-considered product with clear priorities, and the question is whether those priorities match yours.

Verdict — who should buy the iRobot Roomba s9+

Buy the iRobot Roomba s9+ if you need homes that want irobot's d-shape flagship with the strongest suction and you value d-shape for corner cleaning and 40x suction of roomba 600 above raw specification bragging rights. Look elsewhere if expensive would meaningfully reduce your enjoyment of the product. At $999 (a 23% discount off the $1,299 RRP) it represents solid value in a segment where prices routinely climb past $1,500. Cross-shop against the other self-empty vacuums on our list, factor in your specific home layout and household needs, and this one deserves a place on your shortlist.
