Price Difference: Roomba s9+ vs. Roborock s7 MaxV Ultra

The Roomba s9+ is priced at $749, while the Roborock costs $1399 at the time of writing this article. In spite of the huge price difference, both robots are highly sought after. Even though the s7 MaxV is costlier, it delivers excellent features like self-cleaning and auto-filling.

It is worth the price. But if you don’t have that huge a budget, then Roomba s9+ will satisfy your needs. It is the top model from iRobot, so it has the best features.

Which one has better navigation?

The Roomba s9+ relies on a top-mounted camera for navigation. It uses the vSLAM navigation system. However, the Ultra uses the LiDAR navigation system. This system is capable of cleaning perfectly, even in dark rooms. This makes the Roborock more precise than the Roomba.

Roborock s7 MaxV has better navigation capability, which makes it preferable over the Roomba s9+.

Design comparison of both robots

There are two major differences in the design of the Roomba s9+ and MaxV Ultra. The first is the shape, and the second is the side-sweeping brush. The Roomba s9+ has an efficient D-shaped structure for better maneuverability at the corners. The Roborock comes in a regular circular shape.

Both models have a 5-pronged side sweeping brush, but the s7 uses a silicone brush, while the Roomba s9+ has regular bristles. The MaxV Ultra also has Scratch Safe Wheels And Brushes.

Overall, more points go to the Roomba s9+ for its efficient design.

Which robot vacuum is better for cleaning?

With the Roomba s9+’s 3-Stage Cleaning System and amazing Dirt Detection Technology, it can identify areas that need more cleaning and give them heavy focus. The Roborock MaxV, on the other hand, uses Sonic Vibration Technology to detect debris. It is more efficient than Roomba’s dirt detection technology.

The Ultra is equipped with the latest ReactiveAI 2.0 Obstacle Avoidance technology, which uses AI to identify and avoid obstacles. It also has a unique VibraRise Mopping Technology. The VibraRise can detect when the vacuum is climbing on carpets and raise its mop accordingly to avoid dampening.

All in all, the s7 MaxV is equipped with better cleaning technology than the Roomba s9+.

Battery Comparison: Roomba s9+ vs. Roborock s7 MaxV Ultra

The MaxV Ultra has a better battery capacity of 5200 mAh. It takes 4 to 5 hours to complete charging. With this battery, it gives a runtime of 180 minutes. The Roomba s9+ can run for 75 mins with charging of 2-3 hours. It has a battery capacity of 3300 mAh.

If you are okay with the higher charging time of the s7 Ultra, then it is the better choice.

Which one has more additional features?

The MaxV Ultra comes with a bunch of additional features that the Roomba s9+ does not have. Both the vacuums can auto-empty their bins into the docking station, but the Roborock does so much more. The Ultra has a water tank for the mop. It can auto-refill this tank when the water level gets reduced.

Not only that, but the s7 MaxV can clean itself using the water from this water tank. The Roborock’s mop also has a self-washing mechanism where a slider slides across the mop and cleans it up. It also has a child lock feature so that no change will occur in the cleaning mode even if your child toys with it.

Overall, the Roborock s7 MaxV Ultra is equipped with more features.
