iRobot Roomba 860 Review

iRobot Roomba 860

In general, the 800 series has many unique new features and technologies, making it so popular among the people. And the 860 is one of their most advanced models.

Its most appreciated and useful feature is the AeroForce 3 Stage Cleaning System. The way it works is that the rotating brushes pick out the debris on the floor and work together with the suction by bringing them near it. Thus it never misses a spot.

Thanks to it, you are getting up to 50% better cleaning performance. Also, it has five times more the suction power and requires less maintenance than the previous 600 and 700 series’ models.

Besides, the Tangle-Free Extractors prevent all the dust particles, debris, and hairs from clogging the device's interior by breaking them down. So along with its larger storing compartment, this helps to store even more waste.

Moreover, it has a dual-mode virtual wall meaning it has two different modes to keep the device out of reach of an area of the room. Thus it gives you more flexibility.

You can set it to create a 10 feet block opening to keep it out of a specific room. Or you can build a 4 feet radius to make sure it doesn't reach an object or a part of the room. The device can adjust to tiles, carpets, laminated, and hardwood floors.

Furthermore, its powerful lithium-ion battery distributes up to 2 times the cycle than others. That means you can clean an entire room and schedule the next day without having to charge it again. You can program it to 7 days a week for an auto every day clean.

Pros

  • Designed to vacuum without missing a spot or debris
  • Has five times more suction power and requires less maintenance than the previous series
  • Breaks down debris, dust, and hairs and prevents clogging
  • Has a dual-mode virtual wall for keeping it out of programmed areas
  • Lithium-ion battery distributes two times the cycle

Cons

  • Needs restarting or resetting it manually after charge
  • Might get struck

iRobot Roomba 870 Review

iRobot Roomba 870

The 870 is the next model in line in the 800 series and shares many new technologies and features as the previous. It has the same AeroForce 3 Stage Cleaning System, which helps brush the debris towards the suction for more thorough cleaning.

Along with that, it uses a unique Dirt Detect Series 2. It finds dirt around the room using its acoustic and optical sensors for an even thorough cleaning. Also, its side brush spins to clean around the edges and corners of the room.

It has the tangle-free extractors as well to help collect as much dust and debris around the room and carpet as possible. By breaking down all those hairs and pet hairs, it makes sure the system doesn't clog up and is also easy to clean.

Besides, like previous, this model in the series also delivers 5 times more suction power than their 600 and 700 series as well as needs less maintenance. You can also schedule it to any time and day of the week for regular cleaning of the house.

Its XLife Extended life battery provides a longer battery life, which means a thorough deep clean around the house without having to charge it in the middle. The battery life is around one and a half to 2 hours.

Moreover, it has a home base charging station, and it automatically goes back to the station to charge when it is low. So you don't need to check on it for a low battery.

Among other mentionable features is the virtual wall. It has two virtual walls that keep it away from areas or rooms up to dimensions of 4 feet or 7 feet. 

Pros

  • Thoroughly cleans every corner of the room
  • Brushes help to push the debris towards the suction
  • Battery life of 1 ½ to 2 hours
  • Has two virtual walls
  • Uses sensors to detect debris

Cons
