4. Battery

Roomba 650

Roomba 690

  • In terms of size, the Roomba 690 is 13.0 inches in diameter and 3.7 inches in height, weighing 7.8 pounds. Its small size is a plus because this means it can easily fit in tight corners and squeeze under low furniture.

3. Accessories

Roomba 650

A Virtual Wall stops the Roomba from crossing a line marked by a beacon at about 10 ft, preventing it from going to specific areas of the house or close to certain objects. It works only in straight-line paths like through doorways for example. Other accessories include a charging station, battery, HEPA filter, and, a cleaning tool.

Roomba 690

When it comes to accessories the major difference is that this model has a Virtual Wall Barrier with an advanced halo mode, that marks a radius of about 4ft around itself so the Roomba does not hit anything within that area. The barrier is dual, it goes both ways, straight paths and in diameter. It could do so around furniture or a pet area. It also comes with a charging station, HEPA filter, battery and a cleaning tool.

Important Features

The main reason why people buy gadgets like robots is for their performance, capabilities and unique features. Basically for the things they can do, that others can’t and how easily and fast they get these things done.

Let’s see how our two vacuums fit that bill.

1. Capabilities

Roomba 650

  • An Auto docking system allows the Roomba to find its way back to its docking station at the end of every cleaning session and a self-recharge option makes it capable of going to its charger when it runs out of power. All these can also be done manually if you choose to.
  • Using acoustic sensors it locates areas that are particularly dirty and pays extra attention to them. These sensors help avoid risky zones like the edge of stairs and steep falls.

Roomba 690

  • With similar auto docking and self-recharging capabilities like the 650, the added advantage here is that the 690 can be remotely accessed via App and voice command to dock and recharge.
  • As with the 650, the 690 is guided by acoustic sensors that lead it on a safe path and point out dirtier areas.

2. Setup

The setup is relatively easier and much more convenient, it supports up to seven cleaning schedules and the programming is done via the iRobot App or through Alexa and Google assistant which is convenient since it can be done from anywhere.

Cleaning Abilities

Given that the sole purpose of their existence is to clean, this is single-handedly the most important aspect to consider when buying a vacuum cleaner and the Roomba is no exception.

It goes without saying, the big question is Does it do what it’s supposed to do? And how well does it do it?.

1. Cleaning mechanism

Roomba 650

  • An optimized AeroVac technology uses counter-rotating brushes to sweep and gather dirt, dust and debris as well as spinning side brushes to clean edges and sidewalls. It works in a three-stage cleaning process of agitating dirt, brushing it to the center and then sucking it into the dustbin.
  • The Roomba uses infrared light to scan the entire room to avoid bumping into furniture, and a set of proximity sensors at the front tells it to slow down when it comes close to any object or wall especially if it’s moving at full speed.

Roomba 690

  • Cleans with the same technology as the 650 using a three-stage cleaning process of spinning brushes, center brush roll and filtration system.
  • In addition to the infrared light scan, both models have proximity sensors and spring-cushioned bumpers
  • The spring-cushioned bumpers are found at the front of the device, the bumper is attached to a spring and its job is to cushion any impact with hard objects such as walls and furniture.
  • When it comes to parts, both models are identical, they both have wheels and share the same body parts.

2. Usability

  • Spare parts for both models are readily available at affordable rates with third-party retailers.

Final Verdict

While both Roomba 650 and 690 are very similar, they have three visible differences, that add value to the 690 models. Created to replace the 650, the Roomba 690’s advanced features of a Virtual Wall Barrier, wifi connectivity and remote control, tips the scale in its favor.
