The J7 is the smartest of all Roomba models and can identify and navigate around obstacles on the floor, such as a charging cable or dog poop. Some even allow you to create no-go areas the robovac won’t enter. When it comes to smarts, each design offers a number of features including voice control and the ability to map your home so you can schedule cleans for specific rooms as well as the whole floors. The robot vacuum will empty the contents of the dust canister into the bag automatically, so all you have to do is remove the disposable bag once a month.
These higher-tech versions come with a base station that includes a disposable bag designed to hold up to 30 days worth of debris. All four of these models come in two variations a standard model and a self-emptying model, which feature a + in the name. The S9 is also more methodical when cleaning, taking a logical path around your home, while the 694 employs a random route, which can mean cleaning takes longer.īelow the S9, sits the Roomba J7 - the brand’s newest model, along with the i3 and i7. The iRobot S9 is the top-of-the-range model and is 40x more powerful when it comes to suction than the Roomba 694 – the brand’s entry-level robovac, which is known as the Roomba 698 in the UK. There are seven models in iRobot’s Roomba range that are available worldwide, with the suction power and level of smarts being the clear differentiation between the designs.
