Smart floor cleaners should have a compact design so that they can slide and reach all the places in your house that need cleaning. These include under the sofas, beds, and so on. The Roomba 650, 620, and 655 have compact dimensions that enable them to clean all the hidden areas.

Design

The iRobot company does not disappoint in the design aspect. The Roomba 620 comes in a round, modern, and appealing design. The product is short in height. This allows it to get under the sofas and bed with much ease while cleaning. 

It also comes with brushes that have different lengths. This helps to ensure that no dirt is left behind during the cleaning process.

The robotic vacuum comes in a variety of colours that include grey, white, and black so that you can choose your favourite. It measures 17.7 x 16.9 x 4.7 inches, and it weighs 7.9 lbs. The lightweight and compact design make the gadget portable and easy to carry around.

Setup process

Setting up the Roomba 620 is a simple process that will take you just a few minutes. You do not need any technical assistance from an expert to set it up. You just need to follow the guide, press the necessary buttons, and you are good to go.

When you buy the robotic vacuum, it comes with a user's manual. You can follow the instructions on the guide to set it up. In case you still have challenges, you can contact the iRobot's support team on their website.

Features

iRobot Roomba 620 is a random cleaning volume machine. What that means is that it does not have an understanding of its surroundings, and it cannot tell which areas require more or less cleaning. 

One essential feature of the Roomba 620 is the iAdapt system. iAdapt is a system of iRobots software and sensors that allows the gadget to learn the layout of your home. It then makes multiple passes that give your rooms a more comprehensive clean.

The other important feature of the robotic vacuum cleaner is the dirt detect. The dirt-detect uses an acoustic sensor to identify the areas in your house that are prone to be dirtier than others. The cleaner will then spend more time cleaning the areas. The detector will also detect areas under tables, TV stands, and beds that have not been cleaned and clean them. The feature is essential as it helps the cleaner to focus less on the clean surfaces and more on the dirtier ones.

Roomba 620 also has a feature known as auto docking. When the robotic vacuum cleaner is working, and it realizes that the battery is getting low, it will automatically go to its docking station to recharge. The cleaner never fails to locate its docking station.

Additionally, the Roomba 620 robotic vacuum cleaner has an outstanding battery life. When fully charged, the cleaner can run for about 90 minutes, which is commendable.

The gadget also offers you more suction power than its counterparts. This means that more dirt and debris is picked up and significantly saves on energy as it reduces the number of times that the gadget has to go over to do the job. Its dust bin is also bigger, which means you do not have to empty it all the time.

The 3-step cleaning system is another feature the Roomba 620 offers you. This is a system that helps you to clean all the small particles and large debris on your floor and carpets. The system employs dual multi-surface brushes and sweeping edge brush and vacuum suction to do its job.

The virtual wall technology is a technology that creates an invisible wall that confines the gadget in one area. The model, however, does not have an obstacle sensor that would help it not to avoid obstacles on its way.

Lastly, the product comes with a two years warranty.

One vital feature of the Roomba 650 is the convenient scheduling. This means you can schedule your gadget to do the cleaning for a certain number of times in a week without any human assistance. This makes the cleaner very efficient as it does not require you always to be there.

The automatic docking feature is another highlight of the Roomba 650 robotic vacuum. When the gadget is cleaning, and the battery starts to run low, the device goes to its docking station to recharge. Its battery is also known to last for a long time before running low. The 650 can also recharge itself-which is a massive bonus.

Another essential feature is the dirt detect technology. This feature makes the gadget to use more time on dirtier areas and less time on the clean areas. This saves time and energy.

It also has a virtual wall technology. This feature helps confine the gadget in one area and prevents it from going to areas that you set as off-limit. It also has an obstacle sensor that enables it to avoid bumping into obstacles and get destroyed.

The device also can automatically adjust to floors. The gadget detects the distance of the bottom of the robotic vacuum and the floor and pivots accordingly. This keeps the brush rolls in contact with the floor without using too much pressure. The cleaning head also keeps the brush roles to a certain angle so that they can clean thoroughly regardless of the type of floor.

Additionally, the Roomba 650 has a 3 stage cleaning system. It has a side brush that cleans the hard to reach areas, corners, and edges. Then there are the rotating brush roles that loosen the dirt and lift it to the air chamber. Lastly, there is the suction that pulls the dirt into the dust bin.

Then there is the iAdapt technology that enables the robotic vacuum cleaner to navigate your home. This is made possible by infrared and acoustic sensors.
