Since its introduction in 2002, the Roomba models have been considered to be the most effective brand of robot vacuums which serves the purpose of cleaning. It gives a tough competition to all the other brands marketed with its unique features. Let us look into them in a detailed note.

It comes with a sealed gearbox along with the detachable filters and brushes. Unlike the previous models, it is easier to remove the collected debris and dust sticking in the brushes.

The Roomba models are being built with the dirt sensors in all its models that are effective in dirt detection. This latest version also features dirt detecting acoustic sensor combined with the optical sensors for clear vision to map the areas of dirt.

The Roomba 770 has a 3 stage cleaning system to lift deep dirt and debris from the floor and the carpet area. The presence of the spinning side brushes enables cleaning along the edges of the walls. The counter-rotating brushes are designed to perform functions similar to a broom and the brush to sweep and pick up dirt effectively.

The suction capacity used is the aero vac 2 technology, which helps in removing any hidden debris including pet hairs. It is also equipped with the dual HEPA filters to enable the emitted air to be cleaner and safer.

With the help of the self-adjusting cleaning head suspension, the device automatically switches from cleaning the carpet to the floors without the necessity of instructing it manually.

The on-board scheduling, offers pre-scheduling of the tiny device, to perform cleaning at a particular time. This can be done up to seven times in a week.


The Roomba uses iAdapt technology for navigation. This is a technology which comprises of software and sensors with a low profile design to make the roombas clean more effectively by making a number of passes, avoiding the staircases, cleaning the area around and beneath the furniture, and cleaning along the wall edges and corners.


It is made with the ease of using the control pads. As it charges on itself, it is equipped with a home base technology to make the roomba get to the dock as soon as it gets low on battery. There is an indicator that displays to empty the bin whenever it is full. It has effective cleaning strokes that pick up all the dirt and perform filtering to enable breathing the cleaner air.


The tiny device is louder than its rivals. It is reported that it forgets the dock at times. Even though the bin is built bigger, it can still be made bigger to incorporate more debris. It is not able to clean the stairs and gets tangled between the rugs.
