Cleaning | Roomba

Part 1. Spinning Side Brush

As Roomba’s body is round in shape, cleaning dirt that is against a wall would be difficult if not for the spinning side brush it is equipped with. This brush sticks out of Roomba, spins and kicks up dirt or dust and then directs it under Roomba to be vacuumed.

Part 2. Agitator Brushes

These are located on the underside of Roomba, and consists of two counter rotating brushes that traps and deposits dirt directly into Roomba’s dirt bin.

Part 3. Vacuum

The vacuum works like a traditional vacuum cleaner, and sucks dirt into the dirt bag.

CLEANING POWER

Roomba’s cleaning ability is made up of a three part system:

Advanced Functions

While cleaning, there are times when a certain spot on the floor needs more attention than others. This is when the dirt sensors, located on the underside of Roomba just above the agitators, come into action. The dirt sensors are acoustic impact sensors and respond to vibrations made by dirt on the metal plates of the sensors. Hence, more dirt causes more vibrations and the sensors tell Roomba to clean the area more thoroughly.

Limitations

One problem with most Roomba models is the amount of hair that gets trapped in the agitator brushes. Be it human or pet hair, the accumulation of hair is not only a hassle to clean but also impairs Roomba’s performance. So besides emptying the dirt bag when it is full, Roomba users also have to manually dismantle the agitator brushes and rid it of trapped hair from time to time.

AeroForce Technology

In the latest Roomba 800 series, new Aeroforce technology overcomes the trapped hair problem that plagued older models. Aeroforce extractors replace the old agitator brushes in the 800 series. These dual counter rotating extractors incorporate a durable rubber thread design that grabs and breaks down dirt and debris from any floor type. They sweep and comb your carpets just like the bristle brushes on the older Roombas do, and since the extractors can be squeezed closer together, air being pulled in between them by the vacuum is accelerated more, effectively increasing the robot's suction power. At the same time, the overall size of the cleaning head has been shrunk, making more room for the dust bin, which translates into users having to empty it less frequently.
