There is no doubt that the iRobot Roomba is among the best robotic vacuum cleaners, if not the THE best one. Yet, buyers might get lost because there are actually many Roombas. Currently, iRobot promotes 8 Roomba versions in 2 different series: the 600 series and the 700 series. Prices range from approx. $325 up to nearly $700 for the luxurious Roomba 790.
To help you pick the one that best fits your needs, we made a short list of 3 Roombas we describe below. They are representative of the latest Roombas, since the others differ basically in the number of spare parts (filters, area delimeters, …).
The Roomba 620: the Budget Roomba
If you have a tight budget and a small area to clean, take the Roomba 620
for approximatively $325. It does the job, but you need to launch the cleaning manually by pressing the clean button. Once your home is cleaned or if it runs out of battery, the 620 will find its way back to the charging dock.
The Roomba 650 for Scheduled Cleaning
Vacuums are noisy, and the Roomba is no exception. It’s better to run it while you are away, for example during work hours. The Roomba 650
makes it easy for you with its scheduled cleaning mode. Besides, it comes with a Virtual Wall beacon that allows you restrict areas covered during a cleaning cycle. It acts as a wall, so the Roomba will bounce away and thus focus on a particular room, or avoid some region.
The Roomba 780 for Large Houses
The iRobot Roomba 780
comes with several improvements. First, it uses the new generation Virtual Walls named Lighthouses that confines Roomba in one room until it is cleaned, before moving to the next room. The Lighthouse can also be used to block off-limit areas like plain Virtual Walls. Another feature of the 780 is the full bin indicator that lets you know when the bin has reached capacity and needs to be emptied. This is useful since latest Roombas (including the 600 series) fill the dirt bin more evenly, requiring you to empty it less often.
Having pets or allergies is yet another reason to choose the 780. It comes with dual HEPA air filters that capture even tiny dust particles. It also has two sensors to find dirt: one optical and the other acoustic (the 600 series have only the acoustic sensor). Besides, in areas where excessive debris is sensed, the 780 employs a back-and-forth cleaning pattern, which is more effective than the spiral pattern used in former Roombas.
