iRobot Roomba j7+ vs. Dreame L40 Ultra: A Detailed Comparison

## iRobot Roomba j7+ vs. Dreame L40 Ultra: Detailed Comparison

Choosing the right robot vacuum cleaner can seem like a daunting task, especially when there are so many options. Today, we’re going to compare two popular models in detail: the iRobot Roomba j7+ and the Dreame L40 Ultra. Both promise to keep your floors clean, but each has its own pros and cons. Let’s take a look at the features of each robot.

Cleaning Performance

Roomba j7+ and Dreame L40 Ultra are designed to handle different types of floors, from hard surfaces to carpets. The Roomba j7+ has a patented dual brush roll design that is especially effective at picking up pet hair and debris from carpets. However, on hard floors, it pulverizes coffee grounds rather than sweeping them up.

The Dreame L40 Ultra, on the other hand, does a great job on both hard floors and carpets, effectively removing dust, pet hair, and debris. It also features retractable side brushes and mop attachments for more thorough cleaning of edges and corners. The Dreame does a better job than the Roomba with small debris on hard floors.

Obstacle Avoidance

When it comes to getting around the house, both robots take their own approach. The Roomba j7+ uses its front-facing camera and artificial intelligence to identify and avoid obstacles like cables and shoes. While this is a great method overall, it’s not perfect and can bump into furniture or get stuck on unfamiliar objects.

The Dreame L40 Ultra combines LiDAR, cameras, and sensors to avoid bumping into obstacles. The system is very effective and can avoid furniture and other obstacles with amazing accuracy. Dreame is less likely to get stuck, but can still collide with very small or low objects. Roomba is more cautious and Dreame is more confident, but both have their moments.

Auto Dustbin Cleaning and Self Cleaning

One of the biggest conveniences of modern robot vacuums is the ability to empty the dustbin on its own. The Roomba j7+ comes with an automatically emptied clean base that can hold up to 60 days worth of garbage. It has a compact and aesthetically pleasing design and even accommodates a spare dust bag. However, it is quite noisy when emptied - the sound is reminiscent of a jet engine.

The Dreame L40 Ultra solves this problem with a self-cleaning docking station. This docking station not only empties the dust bag, but also washes and dries the mop head and fills the water tank. This hands-free approach is truly revolutionary and makes vacuuming much easier. The Dreame dock is big and bulky, but for many users the extra functionality is worth it. Personally, I love that I don’t have to empty the dust bag or clean the mop attachment every day.

Mop Functions

Both models have mop functions, but approach it differently. The Roomba j7+ has an innovative cleaning system with a metal lever that raises the mop to avoid carpets and an electric pump for cleaning fluid. It does a great job on tiles and can tackle some dirt, but it’s not a magic wand.

The Dreame L40 Ultra uses two rotating nozzles that automatically lift up when they hit the carpet. This allows you to vacuum and clean at the same time, saving you time and effort. The nozzles also automatically clean and dry in the dock, always ready for the next cleaning cycle. We found the cleaning process with the Dreame mop to be more thorough and convenient, especially with the self-cleaning feature.

App and User Experience

The Roomba j7+ has an easy-to-use app that lets you set schedules, create no-go zones, and customize cleaning settings. It also supports voice commands. However, the app is not perfect and sometimes the robot stops working or does not return to the dock.

The Dreame L40 Ultra also has a handy app with extensive customization options including room management, cleaning schedules, and mop pad settings. The app is great overall, but it could be improved with more advanced customization features, such as saving cleaning modes. We found both apps easy to use, but we found the Dreame app to be a bit more complex and feature-rich.
