Roomba 690 vs. 675: Differences and Comparison

There are a few differences between these two robot vacuums. The differences are so significant, anyway.

Virtual barriers

Roomba 690 comes with one dual-mode virtual barrier, which helps to guide the bot’s movement around the room. The 690 vacuum cannot penetrate into places where the virtual wall is being set; instead, it creates a bend and continues cleaning, ignoring the environment covered by the virtual barrier. Unfortunately, Roomba 675 doesn’t come with this feature.

Winner: Roomba 690


Roomba 690 is costlier than Roomba 675. Considering the technical specifications, features, and technologies, these units aren’t so different. Thus, the 675 model offers great value for the price, while the 690 appears to be costlier with no special difference. The filters, brushes, motor, filters, and many other important parts of these robot vacuums are the same. In this aspect, it is apparent that Roomba 675 wins over the 690 model because it saves you reasonable cost and still offer the same value as the 690 model would deliver.

Winner: Roomba 675

Recharge and resume

Although both Roomba 690 and 675 automatically dock and recharge, the 675 model won’t resume cleaning after charging. However, Roomba 690 will automatically dock itself, recharge, and resume cleaning from where it stopped. That’s a big advantage over Roomba 675; it saves the owner the stress of carrying the bot from the dock station to where it stopped cleaning. Auto recharge and resume feature is seen in high-end Roomba vacuums, but the 690 unit includes this feature to offer its owner a commensurable value for the price tag. It takes around three hours for either of these robo-vacs to charge fully.

Winner: Roomba 690

More accessories included in the box

When you buy Roomba 675, it comes with all the important accessories, excluding extra options. On the other hand, when you buy the Roomba 690 vacuum, it does not only include a virtual barrier unit but also comes with extra filters and extra cleaning tools. These accessories included in the box with Roomba 690 are quite important.

Roomba 675 vs. 690: Which is a Better Roomba?

Based on cleaning performance, overall value, and features, it is quite impossible to overlook the capability of the Roomba 675. Unless you’re looking at it from the point of the benefits of the virtual wall barrier, the Roomba 675 is quite expensive compared to the 690 models.

For a powerful vacuum with good cleaning performance, great battery life, easy Wi-Fi connectivity, and voice control ability, the Roomba 675 is certainly a great option.

Features and Parts of the Roomba 675 and the Roomba 690

Accessories included in both Roombas have notable distinctions. However, both models have the following accessories and parts in common:

  • Robot Vacuum
  • HAPA Filter (2)
  • Spinning Brush
  • Cleaning Tool
  • Charging Station
  • Battery
  • User Guide.

However, the accessory that separates the two models is the; Virtual Barrier Wall (dual-mode).

The Virtual Barrier Wall functions to block off certain areas of your floor plan that you don’t want the Roomba to access. This can be an effective tool when you’re cleaning larger floors or overloaded layouts with too many obstacles.

The virtual barrier dual-mode is very much capable of blocking off a radial area up to 4’ in circumference or a liner path up to 10’ long. This will help in protecting a variety of areas including pen concept wide spans, hallways, as well as sensitive areas such as pet food areas or furniture.

Roomba 675 vs. 690: Performance Level

So far we’ve analysis the outside quality of both Roombas, how about we analyze the inside cleaning performance.

The performance level of each of these vacuums is based on several key factors, which include:

  • Filtration system
  • Brushroll style
  • Motor
  • Battery
  • Cleaning tests

Each of the above factors functions together to establish the general cleaning performance.

Filtration System

The Roomba 675 and the Roomba 690 use the AeroVac filtration system. This system, however, is slightly less efficient than its successor. Regardless, the AeroVac isn’t bad by any measure. The AeroVac in both vacuums is still a HEPA filter.

Brushroll style

The Roomba 675 and the Roomba 690 work with a bristle-style brush roll. This is unlike the rubberized brushroll in advanced models such as the Roomba 980 and 17+
However, the bristle style offers a lesser price point and is effective especially on hardwoods. Likewise, the brush roll tends to struggle with fine debris type on carpeted floors.

Motor and Battery

According to our findings, both the Roomba 675 and the Roomba 690 uses the same motor and work with similar 1,800 mAh batteries. They both have the same 90-minute operational time.

The Cleaning Performance of Roomba 675 and the Roomba 690

All of the above features help in determining the general cleaning performance level of each model.
Due to the software and hardware similarities between the Roomba 675 and the Roomba 690, we can theoretically assume that the cleaning performance level would also be basically the same.

The recent operational test we carried out on the Roomba 675 is where our research findings are majorly based. A full cleaning performance test done at Modern Cycle include 12 different tests; that’s on four different types of debris (pet litter, cereal, sugar, rice) and three different types of floors (low pile carpet, hardwood floor, and high pile carpet)
On the hardwood floor cleaning test, the cleaning performance was relatively excellent.

The Roomba 690 eliminated up to 96.5%+ of all types of debris( cereal 100%, pet litter, 96%, rice 98%, sugar 95%).

However, the Roomba 675 performance on the hardwood floor proved to be slightly better. It removed up to 99% of debris on the hardwood floor. While the total low pile cleaning performance on low pile carpet was impressive as well. It recorded 3 of the 4 tests, with a score of 97%+ (cereal 100%, pet litter 98%, sugar 70%).

The overall score on sugar wasn’t great; nonetheless, this was a fair score for most available robot vacuums. The ultra-fine sugar substance tends to be difficult for robot vacuums to remove.

Likewise, the high pile carpet cleaning test performance is almost exactly with the low pile carpet cleaning results ( cereal 99%, pet litter 99%, rice 99%, sugar 67%). 99% of the debris was eliminated on 3 of our cleaning research tests.

The only issue here is the sugar test score, which only made 66%. Again, this is not really a bad score for a robot vacuum. Most robot vacuums tend to struggle in removing sugar on carpets.
