The iRobot Roomba 670 is part of the Roomba 600 Series, it’s one of the entry-level models iRobot released. This model is a budget-friendly vacuum robot but it still provides excellent cleaning performance and does have some smart features too. This  model is perfect for those who are planning to get a vacuum robot for the first time or for people who are on a budget.

The Roomba 670 is great for small to medium-sized homes and can clean dirts, dust, and hair on different flooring like carpets, vinyl, hardwood, tile, and linoleum. It supports WiFi connectivity and has Smart Home Integration via Amazon Alexa and Google Assistant.

Design and Dimensions

Just like any other Roombas, the Roomba 670 is also a round device with its control buttons at the center. If you are familiar with the logo of Spotify, the device looks like that. It also looks like a big cd player. Also the Roomba 670 is color white compared to other black Roomba models. It does not come in color black or any other color for that matter. The control buttons at the center of the device consists of the following: the Clean/Power button, Spot button, and Dock button. The Roomba 670 is 3.5 inches tall and weighs 6.7 lbs. Just like other Roombas, the Roomba 670 also has a duo brush design, a unique patented design for all Roombas.

Performance and Technology

When it comes to performance, the Roomba 670 may be a mid-range Roomba unit, but it is powerful. Despite it being a budget-friendly vacuum robot, it is equipped with smart features that other advanced Roomba models have. It uses a 3-stage cleaning system. It loosens, lifts, and suctions dust, dirt, and hair from your hardwood, tile, linoleum, or carpet flooring. It also uses two different brushes–one brush called the Dual Multi-Surface Brushes that work together to grab dust, dirt, and large debris and the other, Edge-Sweeping Brush, a brush that is specially designed at a 27-degree angle to sweep debris away from edges and corners.

The Roomba 670 has Dirt Detect Technology that detects the areas that are dirty and will thoroughly clean that area by going back and forth until it’s free from dirt, dust, and other debris. It also has an AeroVac filter that filters fine dust and particles. Another technology that the Roomba 670 uses is the iAdapt Technology. This technology prevents the device from falling off the stairs or from bumping on the wall because it allows the Roomba 670 to move around the room and detect walls, bumps, and cliffs.


The Roomba 670 is a pretty impressive vacuum robot and the battery does not disappoint. It is equipped with lithium-ion batteries and runs for up to 90 minutes. It also docks and recharges automatically when the battery is low, however, the device does not resume cleaning or return from where it left off. The battery of the Roomba 670 is better than the kind of battery the latest Roomba units use. The more advanced Roomba units use nickel-metal hydride batteries and they run out of power faster than the older models that use  lithium-ion batteries.

Navigation and Connectivity

The Roomba 670 does not use smart navigation. It has random navigation and pinballs around the room randomly as it cleans because unlike the more advanced Roomba units, the Roomba 670 does not have a camera to map your home and does not remember the layout of your home. However, it does support WiFi connectivity which means that you can use the iRobot Home App and monitor and schedule cleaning from anywhere using the app. With the WiFi connectivity, the device can also recognize voice commands via Amazon Alexa and Google Assistant.

While the Roomba 670 supports WiFi, it does not have Keep Out Zones feature– a feature advanced Roomba units have, where you can draw  boxes on the iRobot Home App on your phone to keep your Roomba unit out of certain places.

Pure Clean Robot Vacuum Cleaner

The Pure Clean Robot Vacuum Cleaner is among the cheapest that you can find in the market. It uses the same lithium ion battery that the Roomba a670 uses and can also run for up to 90 minutes. It also has anti-fall cliff sensors that guide the device from falling off the stairs. This robot vacuum also has dual rotating brushes and it is allergy and pet friendly. It is almost the same as the Roomba 670, however, it does not support WiFi and does not have Dirt Detect Technology.

iRobot Roomba i7+

This iRobot Roomba model is one of the latest models and it is far more advanced than the Roomba 670. It has all the smart features of the Roomba 670 but it is so much better. Instead of using the AeroVac filter, the Roomba i7+ uses a HEPA filter that can capture ultra fine particles, as small as 0.3 microns. It also has a Power Lifting Suction that delivers 10x more air power. The Roomba i7+ also has Imprint Smart Mapping and Imprint Link Technology which means the device uses smart navigation and it adapts to your home. It also has the Keep Out Zone feature that the Roomba 670 lacks. This Roomba unit also has a Clean Base Automatic Dirt Disposal with AllergenLock bag that can hold up to 60 days of dirt, dust and hair. The Roomba i7+ is so advanced but it costs a lot more than the Roomba 670.

Robocist 850 Robot Vacuum

The Robocist 850 Robot Vacuum is on par with the Roomba 670 in terms of features and performance but it is slightly cheaper. This vacuum robot has 100-minute running time compared to the Roomba 670’s 90-minute running time and just like the Roomba 670, it also automatically docks and recharges itself when the battery is low. It also supports voice command via Amazon Alexa and Google Assistant. Plus it has a remote control, a piece of accessory that the Roomba 670 does not have. The Robocist 850 can also be linked to its own app that you can download to your phone. And like the Roomba 670, it is also equipped with cliff and bump sensors to prevent it from falling down the stairs. It, however, does not have Dirt Detect Technology.

What I don’t like about the Roomba 670

  • Does not have a HEPA filter.
  • Does not come with a remote control.
  • Does not have Smart Navigation.
  • A noisy device.


The Roomba 670 is a decent vacuum robot. For its price, it has a lot of smart features that latest Roomba units also have. It looks very sleek and modern too. Considering that it is an entry-level, mid-range iRobot Roomba model, the smart features it has are very impressive. It is WiFi-enabled and supports the iRobot Home App. You can also use voice commands via Amazon Alexa and Google Assistant. The Roomba 670 also has Dirt Detect technology and has been equipped with bump and cliff sensors to prevent it from falling off the stairs.

For a lower price, the Roomba 670 is already a catch. If you are looking for a decent vacuum robot that won’t break the bank, the Roomba 670 is a good choice. Of course, there are other brands or Roomba units that are cheaper but this vacuum robot does the job well. The only thing that I think this device is missing is the HEPA filter, although the AeroVac is a good filter, the HEPA filter captures ultra fine dust, debris, and allergens that the AeroVac can’t filter. I also think that it would be nice if the Roomba 670 has smart navigation instead of the random one.
