The Roomba 670 and 675 are both part of iRobot’s affordable 600-series robot vacuums, designed to provide an accessible way to automate your home cleaning routine. Although both models offer reliable performance, they have a few key differences that may influence your purchasing decision. This detailed comparison will help you choose the right robot vacuum for your needs, based on design, features, and overall cleaning performance.


Design and Build Quality

Identical Dimensions with Subtle Variations

The Roomba 670 and 675 share nearly identical dimensions and weight, but there are minor differences in their finishes and aesthetic details.

Dimensions 13.4 x 3.7 inches 13.4 x 3.7 inches
Weight 7.8 lbs 7.8 lbs
Finish Matte Black Matte Black with Silver Accents

The 670 has a standard matte black finish, while the 675 adds a small silver accent, giving it a slightly more polished appearance. However, the overall look is quite similar, making the design differences negligible in terms of functionality.


Cleaning Performance

Same Cleaning Power for Both Models

Both the Roomba 670 and 675 deliver solid suction power and use the same basic cleaning system. This includes a combination of a main brush and side brush to effectively clean along walls and edges.

Suction Power Standard Standard
Brush System Dual Multi-Surface Brushes Dual Multi-Surface Brushes

Performance on Different Surfaces

Surface Type Roomba 670 Performance Roomba 675 Performance
Hardwood Floors Good Good
Low-Pile Carpets Fair Fair
High-Pile Carpets Poor Poor

Both models are great for hard floors and low-pile carpets but will struggle with deep cleaning on high-pile carpets. The overall cleaning performance is similar in both, with no significant advantage in suction or brush effectiveness.


Navigation and Mapping

Basic Navigation System

The Roomba 670 and 675 both rely on iRobot’s basic navigation system, which uses random pathing to clean rooms. They don’t feature advanced mapping or room recognition technology, which means they might miss spots or take longer to clean a room.

Navigation Feature Roomba 670 Roomba 675
Navigation System Random Path Random Path
Smart Mapping No No
Obstacle Avoidance Basic Basic

Given their reliance on random navigation, these vacuums are best suited for smaller spaces without complex floor plans.


Battery Life and Runtime

Identical Runtime

Both models come with the same battery capacity, providing a similar runtime on a full charge.

Battery Aspect Roomba 670 Roomba 675
Runtime ~90 minutes ~90 minutes
Recharge and Resume No No

Neither vacuum supports “recharge and resume,” which means they won’t automatically continue cleaning after recharging. However, their runtime is sufficient for smaller homes or spaces with minimal obstacles.


Smart Features

Wi-Fi Connectivity and App Control

Both the Roomba 670 and 675 are equipped with Wi-Fi connectivity, allowing users to control them via the iRobot Home app. However, there is a small difference in the app features.

The 675 offers slightly more advanced app control, with additional features like the ability to set up cleaning schedules and receive notifications. Both models are compatible with voice assistants like Amazon Alexa and Google Assistant.


Maintenance and Accessories

Similar Maintenance Requirements

Both models are easy to maintain, with similar dustbin capacities and filters. They don’t come with premium accessories like virtual walls, making them a good choice for users looking for simple robot vacuums without additional costs.

Maintenance Aspect Roomba 670 Roomba 675
Dustbin Capacity 300 ml 300 ml
Filter Type Standard Standard

Neither model includes additional filters or spare parts, but their simple design makes them straightforward to maintain.
