Cleaning comparison – Roomba 675 vs 677

The two models use a combination of two different rollers for extraction. The first roller is a smaller paddled beater roller that agitates the carpet and the second roller, also the primary one is a bristled brush roller that picks up loosened dirt and debris.

The rubber roller doesn’t have a greater function. Both the rollers are enclosed in a cage that adjusts to different floor heights. However, the rubber paddles do not expand far through the cage, less than 1/16 of an inch so they don’t really pick up much dirt beyond the first layer of the carpet fibers.

On the other hand, the brush roller is pretty decent and does most of the work. It will seep into low and medium pile carpet fibers easily but traps a lot of hair, sting and pet fur around the bristles. Though, the two models come with a cleaning tool that helps you unclog them.

The robots perform quite well on hard flooring too. The main floor is cleaned nicely enough, the edges, however may still have a little debris left behind. The side brush spins too fast (a problem not rectified until the Roomba s9+). The edges and corners will be cleaned by it, but not as per your expectations.

 The filtration is also found to be lacking. Using the AeroVac standard filter system, there isn’t any HEPA quality filtration. People looking for in-home allergen reduction won’t be able to find it with these two models. The filters are designed in a manner so as to keep the motor area cleaned and prevent large debris from entering your home.    

Maintenance and operational cost comparison

It is very important to keep your Roomba cleaned and maintained to ensure it works properly and lasts you long. Most of the issues that come with Roomba are because of improper cleaning.

All the constituent parts are really easy to find either directly through iRobot or there are a ton of third party manufacturers.

The cleaning methods for both models are relatively same. The filter and bin should be kept clean so that you don’t face any issues with air-flow restriction and loss of power.

The brushes also need to be thoroughly cleaned every now and then. The pack of filters and brush for iRobot Roombas or replenishment kits are available on Amazon as well as iRobot’s official store as well for $49.99.

If you run out of batteries, they are available for $89.99. All other constituent parts are available to help you care for your Roomba.

The batteries and replenishing kit are the two things that you are most definitely going to need at some point that is why, the care cost of both the models will actually be similar. If you face issues with other parts then you can get them through iRobot official store or Amazon.
