That still makes it a pretty expensive robot vacuum. But, this is the best robot vacuum that you can currently buy. Whether that's from iRobot or another company. So it's definitely worth the money.
The Roomba S9 sports iRobot's very popular 3-stage cleaning system. It also delivers up to 40x the suction compared to its 600 series. That gives you the deepest clean ever from a Roomba robot vacuum. It will also automatically increase the suction, when it knows it is on carpets. That is going to allow it to easily get up all of the pet hair out of the carpet and other dirt too.
iRobot has its PerfectEdge Technology included, which sports some advanced sensors and has a specially designed corner brush that optimizes cleaning deep into corners and along edges.
Like the previous iRobot robot vacuums, it also will map out your home. It can remember multiple floorplans, for your entire home. This is good for those that have multi-level homes. It uses the advanced vSLAM navigation technology, and can gather over 230,400 data points each second. This is going to optimize coverage so that you don't miss any part of the room.
Much like other Roomba robot vacuums, the S9 also has support for the iRobot HOME app, as well as voice support. So you can use your voice through Amazon Alexa or Google Assistant to control the Roomba and tell it when to start vacuuming. With the app, you have the ability to set up a schedule for it to vacuum everyday, and do zone cleaning as well. Among other features.
