iRobot Roomba s9+ vs. Dreame X40 Ultra: A Detailed Comparison

## iRobot Roomba s9+ vs. Dreame X40 Ultra: An In-Depth Comparison

Choosing the right robot vacuum cleaner can seem like a big decision, especially with so many options on the market. Today, we’ll be doing an in-depth comparison of two high-end candidates: the iRobot Roomba s9+ and the Dreame X40 Ultra. Both promise top-notch cleaning, but they each have their own pros and cons. Let’s take a closer look at them.

Cleaning Performance

The Roomba s9+ is a beast when it comes to carpet cleaning. I was genuinely impressed with its ability to pull out embedded dirt and sand. It penetrates deep, not just the surface, and the D-shaped design really grabs the edges and corners for a more thorough cleaning. The suction power is amazing and automatically adjusts depending on the type of floor. However, it sometimes fails to handle large debris and can make an annoying squeaking sound.

The Dreame X40 Ultra, on the other hand, does a great job on both hard floors and carpets. Its powerful suction system effectively sucks up all kinds of debris, from pet hair to spilled cereal. The retractable side brushes and mop are great for cleaning edges and corners, reaching places that other robots might miss. The X40 Ultra also features the Intelligent Carpet Management System, which raises the side and main brushes when they hit wet carpets to prevent cross-contamination.

Self-Cleaning and Maintenance

One of the main benefits of the Roomba s9+ is its self-cleaning brush base. Incredibly conveniently, it automatically empties the dust bag after each cleaning. The upgraded filter is also a nice touch, and the bag has a lifespan of about one month. However, in the long run, you’ll have to splurge on buying replacement bags.

The Dreame X40 Ultra takes self-cleaning to a new level with its self-cleaning dock. In addition to emptying the dust bag, it washes and dries the mop head and fills the water tank. This saves a lot of time and gives the robot a real sense of autonomy. The mop cleaning process can be a bit noisy, but the convenience is worth it.

Navigation and Obstacle Avoidance

The Roomba s9+ uses the camera to map your home, which is generally effective but not as accurate as a lidar-based system. It’s a bit clumsy near obstacles and can bump into things more often than expected; the D-Shape is great for clearing edges, but can make navigation a bit fuzzy.

The Dreame X40 Ultra, on the other hand, has a very effective obstacle avoidance system. It avoids furniture and other obstacles with minimal problems. However, it may not be able to handle very low objects, so you should be careful if there are thin pieces of furniture nearby.

App and Customization

The Roomba s9+ app is user-friendly and allows you to schedule cleaning, assign specific rooms, and memorize multiple floor plans. The Dreame X40 Ultra app is also user-friendly and offers a wide range of customization options. It allows you to customize cleaning modes, set restricted areas, and monitor the robot’s progress. However, some users may find the customization options somewhat limited, such as the inability to save cleaning zones.

Noise and Battery Life

The Roomba s9+ can be quite noisy, especially at maximum power. Battery life is also shorter than some competitors, so recharging and restarting may be necessary in larger homes. The Dreame X40 Ultra vacuum cleaner is also a bit noisy when mopping, but is generally quiet for normal cleaning. The battery life is decent and can be used in most homes without having to recharge while cleaning.

Price and Value

The Roomba s9+ is a premium investment and one of the most expensive robot vacuums on the market. Although it provides excellent carpet cleaning, the high price may be a disadvantage for some. The Dreame X40 Ultra is also more expensive, but has many features that justify its price, including a self-cleaning docking station and an advanced obstacle avoidance system. It’s a significant investment, but well worth it if convenience and thorough cleaning are important to you.
