Their Roomba collection is one of the most advanced, efficient and cost-effective robot vacuums, that is sure to leave you satisfied with the great service that it will provide.

Today, we compare the iRobot Roomba 671 and the iRobot Roomba 690, in terms of design, costs, cleaning power, and other factors. If you are looking to buy a robot vacuum cleaner, the iRobot Roomba 671 and 690 are your best budget options, but which one to choose? Let us have a look.

Design And Build

A sleek design and awesome functionality are what both iRobot Roomba 671 and 690 provide. They both can reach those difficult-to-clean areas in which traditional vacuum cleaners cannot reach, and are effective in cleaning up.

The only difference in their designs is a slight difference in color and other subtle aesthetic properties. The battery life on these two devices is almost the same, even though the 671 has a larger 3000 mAh battery as compared to the 690’s 1800 mAh battery.

Both devices can work for around 90 minutes before returning automatically to their dock for recharging, which usually takes around 120 minutes for both devices.

They are both suited for low pile and medium pile carpet floor types, and hardwood, marble tile, vinyl, ceramic tile, laminate, and linoleum bare floor types.

Cleaning efficiency and features

Both the iRobot Roomba 671 and iRobot Roomba 690 are again very well matched in this regard. They both have the patented 3 stage cleaning system that iRobot devices are known for. They loosen the set in the dirt on the floor before uplifting the debris and cleaning the floors efficiently.

Small debris, hair and large particles can all be easily gathered by both the 671 and the 690. Dual cleaning brushes are another great feature of both devices, and currently no other automatic vacuum cleaners on the market boast of this feature.

These dual brushes work in conjunction with each other; while one loosens dirt, the other sweeps it into the device. This helps in removing dirt from hard to reach corners that other typical vacuum cleaners often miss.

If you have the Google Assistant or Amazon Alexa with you, then you can easily connect your iRobot Roomba 671 or 690 to these devices for a great cleaning experience.

True handsfree cleaning can be achieved when connecting these devices since this allows you to control your robot vacuum cleaners simply using the sound of your voice.

If at all you cannot procure the Google Assistant or Amazon Alexa, then there is nothing to worry. Both devices work flawlessly with the iRobot home app, which can be installed on your smart devices and the robot cleaners then controlled from there.

This allows you to schedule your vacuum to begin cleaning on specific times that you want and get real-time updates on the cleaning process.

Extra features

Roomba 690 dirt detectors

It is in this category that we see the first difference between the iRobot Roomba 671 and the 690. The Roomba 690 has special dirt detectors that can determine the areas of your home which have the highest dirt density.

The robot then provides extra cleaning power and spends more time working on these areas instead of other ones.

Both of these devices are incredibly powerful when it comes to cleaning, but it is this extra feature of the Roomba 690 that truly sets it apart.

Another additional feature for the 690 is that you can add a virtual wall to the device, to prevent it from entering into areas you do not want it to enter into.

Cost and pricing

The iRobot Roomba 671 is priced higher than the 690, at around USD 290 as opposed to the latter priced at USD 250.

This final distinction between the two devices leads us to our decision of which iRobot Roomba device to buy, and the previous category of features discussed has aided us in making a decision.

The final verdict

Both the iRobot Roomba 671 and 690 are awesome devices. They possess unmatched cleaning power, dual brush systems that are yet to be released in any automatic vacuum cleaner out there, and a sleek and subtle design. But the iRobot Roomba 690 takes the cake for us.

With its extra dirt detector feature to help clean out dirt from the filthiest of areas in your home, and a significant cost reduction, the iRobot Roomba 690, even with its less battery capacity, beats the 671 for us.
