Meet the Roomba 620

iRobot Roomba 620

The Roomba 620 only weighs 12.8 pounds, which provides it enough weight to push around the dust bunnies invading our laboratories. At only 3 inches tall, the Roomba 620 is slim to slide under the majority of the furniture.

It will not fit under some of the shelving and cabinets we have, but it was smooth enough to slide those a little bit away from the wall to have cleaning behind them. The Roomba 620 is a technological masterpiece adding acoustic sensors.

We were really impressed that such a tiny vacuum would have this function. The idea behind the sensors is finding places of concentrated dust that tells the Roomba 620 to concentrate its process on that place.

Biggest Attractions

  • Removes tons of dust with regular use
  • Simple, push-button operation
  • Quieter than other robotic vacuum cleaners

While the Roomba 620 model is a simple robot, it’s still a powerful cleaning device. The standard functions of the 600-line help this model reliably remove dust and dirt.

1. Sensor-driven Navigation

The Roomba 620 model uses the iAdapt 1.0 navigation system. When some owners complain that this cleaning design is random, the robot vacuum is actually learning your floor plan whenever it cleans.

When you push the Clean key, the 620 model sets out straight until it encounters an obstacle. It then stores that location and sets off in a new way. Throughout the cleaning operation, it starts to understand the contours of your house.

It becomes more effective as it cleans. An important note about this magnificent system is that the Roomba 620 doesn’t store the map in its memory. It always begins with a clean slate with each cleaning operation.

This could be frustrating if you’re only cleaning one room, as you may think the robot vacuum would figure it out over time. But, this system permits your droid to adapt to its changes in your floor plan.

It means that your Roomba could be used to clean multiple places in your house without reprogramming. Top of that, the obstacle sensors which detect barriers, your Roomba vacuum has Cliff Detect sensors which keep it from falling down from the stairs.

These sensors are perfectly calibrated so that the model could handle the tiny drops that come with its changes in surfaces. When it observes a more significant drop, it‘ll change directions and then stay safe.


The Roomba 620 comes with a Virtual Wall machine that could steer it away from sensitive places by emitting an electronic signal which triggers the obstacle sensors.

You could also use a Virtual Wall to block the doorway and keep your vacuum from leaving a place before it’s totally clean.

2. AeroVac Cleaning System

iRobot Roomba 620

The AeroVac Cleaning system has 3 stages of cleaning power. First, a rotating side brush and 2 main brushes loosen and also lift debris and dirt, putting it in the path of the vacuum cleaner. Next, the dust is sucked into the dustbin. Lastly, the AeroVac filter separates dirt and dust from the air, keeping it in the dustbin.

Most users find that they require to change the filter every 3 months with normal use. You could additional filters online as well.

3. Remote Control

When there’s an unexpected mess, you don’t have time to wait for your robot vacuum to find it. The remote control permits you to guide the Roomba vacuum to the scene of the mess.

This is a helpful tool if you’ve got a bigger floor plan which needs multiple charges to clean. Instead of waiting for the robot vacuum to find new territory, you could guide it to the area where it last stopped cleaning.

4. Rechargeable NiMH Battery

The replaceable hydride nickel-metal battery is the main source of the Roomba’s power. The 620 model has about sixty minutes of cleaning power on a solo charge.

When its charge drops low, it will automatically stop cleaning and seek out its charger. For the ideal results, put your dock in place with open space, so it’s easy to find. If the robot vacuum registers too many obstacles nearby, it might fail to find the dock and run out of charge.

5. Clean, Spot, Dock

There are 3 buttons on top of the 620 models. The Clean key is the biggest button that sends the model on a general cleaning mission.

Although you can’t schedule a cleaning for the 620 models, some owners make a habit of pushing the Clean key as they head out the home for the day.

The Dock key interrupts the cleaning operation and sends the Roomba vacuum back to its docking station. The final key is a special cleaning mode.

Whenever you put your robot vacuum in the center of a spill and then press the Spot key, it starts cleaning in a tight, spiral design.

Unless you interrupt the operation, it will continue this design until it has vacuumed a circle about three feet in diameter. Hopefully, you’ll not be dealing with so many spills, which are much bigger than that.
