Roomba 860

The Roomba 860 has a number of unique features that make it an efficient robotic cleaner. On the top of the list are dual counter-rotating, rubber debris extractors that effortlessly grab dirt from all types of flooring—from hardwood and linoleum to carpet and tile. The extractors are designed in a way that minimizes the chance of hair getting tangled and debris getting clogged inside. Both lower the need for maintenance. The overall cleaning capability has been enhanced, compared to earlier models. And like the Roomba 805, you can schedule up to 7 cleaning runs ahead of time. Overall, this is an attractive option among robotic cleaners.

Key Features

  • The Roomba 860 features responsive navigation technology that enables it to vacuum the entire house without interruption or missed areas. It moves well around furniture and along walls.
  • The unique Aeroforce Cleaning System comes with debris extractors that have a durable rubber tread design. They can grab dirt from any type of flooring and reduce the chance of it getting tangled inside the vacuum. This lowers the need for brush maintenance.
  • Its Gen 2 motor enhances the vacuum’s cleaning performance up to 5 times and requires less maintenance than the motors of older models.
  • The Roomba 860 operates with Dirt Detect Series II technology. It is built on optical and acoustic sensors that detect particularly dirty areas of your home and guide the robot to clean them with a combination of agitation, brushing, and suction.
  • You have the option to set a virtual wall barrier. Roomba’s Virtual Wall Mode keeps the vacuum in areas you want cleaned and out of the ones that you don’t. Additionally, Halo Mode keeps it away from sensitive items like pet bowls or breakable decorations.
  • The included HEPA filtration system is of particular value to people suffering from allergies. The filter is able to trap dirt particles as small as 0.3 microns at an efficiency level of 99.9%.
  • The included lithium-ion battery has a life cycle approximately 3 times as long as that of other batteries. It charges quickly and has a low self-discharge. This means the vacuum can operate longer, with a better cleaning performance and less required maintenance.


  • The Roomba 860 requires little to no maintenance.
  • Like the Roomba 805, the 860 can be scheduled to clean at predetermined times. You can select up to 7 cleaning runs per week.
  • The Roomba 860 is an efficient and powerful vacuum. Its suction power is far superior to older models. It shortens the time it takes to effectively clean the entire house.
  • The device automatically returns to its docking station when the battery charge starts to run low. There is no need for the user to keep track of the battery, since the Roomba does it for you.


  • The Roomba 860 cannot be controlled via Wi-Fi. In today’s connected world, and with technology rapidly advancing, most electronic devices can be controlled via an app or a Wi-Fi connection. That the Roomba 860 does not offer this feature is a drawback.
  • Cleaning corners is a challenge for the Roomba 860, largely because of its circular shape. Thus, it is possible for some dirt to not be swept up.
  • This robotic vacuum tends to move erratically. While it is part of the cleaning method, it can be an odd sight to see the unit lurch around the floor.

Overall Performance

The Roomba 860 has been designed to enhance its overall cleaning capability. Improved suction power and better sensors, paired with the option to set virtual walls, ensure that the vacuumed areas are left spotless. While the motor is not as powerful as the ones included in other models, the longer battery life enables the vacuum to make more cleaning runs to ensure no dirt is left behind. In that regard, the Roomba 860 compares favorably to other robotic cleaners. The biggest drawback is the Roomba’s difficulty in cleaning corners.
