iRobot really impressed us with the Roomba i7+, the first robot vacuum we tested than can clean your house and clean itself by emptying its dustbin. Did it get any much better than that? As it happens it could. iRobot’s latest vacuum, the Roomba s9+, takes what we like about the i7+ and puts it in a fresh condition that’s better at reaching difficult areas, with four times the suction power. And with a good amount of sensors and camera-based navigation, it learns the layout of your house as time passes. At $1,399.99, it is the priciest robot vacuum we’ve tested to date. But its powerful suction, smart navigation, and capability to empty itself out helps it be the best one you can purchase and our Editors’ Choice for high-end models.

Design
As opposed to the standard circular condition you see of all robot vacuums (include almost every other Roomba), the s9+ includes a D form like the Neato Botvac D4 Connected. This enables it to get deeper into corners and align itself against walls.

Apart from the change in shape, in addition, it looks a whole lot sleeker compared to the i7+, with an eye-catching copper-like lid that matches the accents on the Clean Base (more upon this in an instant). It is also smaller, measuring 12.3 inches in diameter and 3.5 inches tall, weighed against the prior model’s 13.4-by-3.7-inch dimensions.

The most notable of the vacuum houses the RCON sensor (room confinement), clutter sensor, a camera, and buttons for Clean/Power, Spot Clean, and Home. Addititionally there is an LED ring indicator that glows red when charging, white when cleaning, and blue when connecting to Wi-Fi. The medial side of the vacuum houses a wall sensor. Under the lid you will discover the dustbin and filter together with the carrying handle.

Underneath of the s9+ houses a corner brush, multi-surface rubber brushes, brush caps, a brush latch, a brush frame release tab, charging contacts, and cliff sensors. In addition, it houses the dirt disposal port, floor tracking sensor, and rear caster wheel.

Then there’s the Clean Base (which should be connected to a wall outlet), where in fact the robot docks, charges, and empties its dustbin. Leading holds an LED indicator, together with the canister lid, exhaust vent, wheel wells, and debris evacuation port. When the s9+ docks itself, all of the dirt it collected is automatically sucked in to the Clean Base, which stands up to 30 cleanings of debris; the iphone app notifies you if it is time to swap it out for a fresh one. The vacuum includes two bags, and you could buy more in packs of three for $14.99.

Additional accessories include a supplementary filter and a supplementary corner brush. More Clean Bases are for sale to $299 if you wish to include them to other rooms. On the other hand, you can purchase the s9+ without the Clean Base as the standard s9 for $1,099.99.

Setup, App, and Voice Control
To pair the s9+ to your phone, you need to download the iRobot Home app, which is designed for Android and iOS devices. Setup is really as simple as creating a merchant account, choosing your unique vacuum model, selecting your Wi-Fi network and entering the password, then pressing the location and Home buttons on the vacuum until you hear it beep.

Once connected, the key screen of the iphone app features a major Clean button to start out and prevent vacuuming, with the battery level displayed above. Underneath of the screen has tabs for Schedule, History, Smart Maps, Help, and Settings. Tap the Schedule tab to assign the vacuum to completely clean on a particular day and time. THE ANNALS tab introduces a log of your cleaning sessions. Smart Maps shows the layout of your property, which requires a few rounds for the vacuum to understand. After that you can label specific rooms to send the vacuum to unless you want it to completely clean the complete home. The Help tab houses care and maintenance manuals, an owner’s guide, FAQs, and warrantee information. The Settings tab is where you could change your Wi-Fi information, switch the language, locate the vacuum, and perform a factory reset.

You can also hook up the s9+ to Amazon Alexa or Google Assistant via their respective apps. Once connected, you can issue voice commands through your phone or other compatible devices to tell the vacuum to start out, stop, pause, or get back to the dock.

Performance
The s9+ has terrific navigation functions and rarely required manual intervention in testing, something very important to a totally hands-off experience. I followed the s9+ around since it cleaned, as watched since it were able to wiggle its way around chairs and tables easily. Its relatively low profile also allows it to create its way under most low-clearance furniture.

It also gets the strongest suction we’ve observed in a robot vacuum. In testing, the s9+ sucked up dust, hair, and all the manner of debris without issue at all. In addition, it changes its suction strength automatically according to be it cleaning carpet (heavier suction) or wood and tile (lighter suction). Generally, it cleans in a back-and-forth pattern in open spaces, and its own D form is ideal for tough-to-reach areas. In testing, it could graze against walls, allowing the medial side brush to seize dust and debris in corners.
