Which is better: Roomba i7/i7+ or Roborock s7?

The Roborock s7 is a better robot vacuum than the Roomba i7. It has an extended battery life and sonar navigation which is excellent in the price range. The biggest pro is the extra mopping feature. But if you are looking for a cheaper piece, then the i7 should be your choice.

We have seen people favoring Roombas over any other vacuums. But it would be a mistake in this case.

The i7+ is exactly similar to the i7 except for its docking station. It comes with a Clean Base docking station that not only charges the vacuum but also empties its bin.

It suctions the contents of the dustbin from a hole at the bottom and transports it into the docking station. There, the contents are sealed in a vacuum bag.

It can hold debris collected from 30 cleaning cycles before the sealed vacuum bag needs to be taken out. The Clean Base will indicate when you need to take out the vacuum bag.

Their products are built using advanced technologies and undergo rigorous testing. This makes Roborock a trusted choice for customers seeking dependable cleaning solutions.

It offers a powerful combination of sweeping and mopping functions. It thoroughly cleans various floor surfaces, thus making it an ideal choice for a versatile and efficient cleaning solution.

Roomba i7/i7+ vs. Roborock s7 Comparison

Let’s see in detail how the three robot vacuums differ.

Which one costs less? Price compared

You will find a whooping price difference of $100 between the i7 and s7. But even though the s7 is costlier, it comes with an additional mopping feature.

But if you go for the i7, you might have to get another robot for mopping, which is definitely going to cost more than $100. The i7+ costs $200 more than the i7, which doesn’t make sense as the only additional feature is the self-emptying capability which we also get in the s7.

Thus, we think that getting the Roborock s7 is the better choice.

Who Gives A Better Cleaning Performance: Roomba i7/i7+ or Roborock s7?

Cleaning performance-wise, there’s no doubt that s7 has the lead. It has 2 cleaning modes: vacuuming and mopping. In comparison, the i7 and i7+ can simply vacuum.

Due to the mopping cleaning mode, the s7 has a greater suction power of 5100 Pa, while the i7+ only has a suction power of 1700 Pa.

Roborock s7 will undoubtedly give you a better cleaning experience than the Roomba i7/i7+.

Battery Performance- which runs longer?

Even though all these robot vacuums have Lithium Ion batteries, there’s a huge difference between the battery capacities of Roomba and Roborock. The i7 and i7+ run for 75 minutes on a full charge with a battery capacity of 1800 mAh.

It takes approximately 2 hours for the i7/i7+ to charge. On the other hand, the s7 has a battery capacity of 5200 mAh and a runtime of 180 minutes. s7 takes around 4 to 6 hours for a full charge.

If you are okay with the more charging time of the Roborock s7, then go for it; otherwise, choose the Roomba i7/i7+.

Build Quality And Design

The s7 is of superior build quality to the i7 and i7+. It has fewer parts that require regular replacement and hence incur less cost. It is slightly bigger in size than the i7/i7+. But it is significantly heavier.

The reason is the extra mopping technology in the s7. The Roomba i7 and i7+ present a sleeker look with a Charcoal Grey color. You have Black and White options to choose from for the s7, so that’s definitely something.

We would definitely go for the Roomba i7/i7+ as it carries a modern design with a slimmer body type. But if you prefer a stronger build quality, then go for the Roborock s7.

Dustbin and Tank Capacities

The i7 and i7+ have a dustbin capacity of 0.5 L, while the s7 has a dustbin capacity of 0.47 L. But the difference in their capacities is not that significant. In addition to a dust collection bin, the s7 also has a water tank with a capacity of 0.3 L. The water tank is used for mopping.

Cleaning Technologies Compared

Both robot vacuums have Smart Mapping Technology, which maps your home and memorizes the nooks and corners for better cleaning. The s7 uses Sonic Vibration technology for better detection of dust, dirt, and other particles.

In comparison, the i7/i7+ uses visual Simultaneous Localization And Mapping (vSLAM) Technology to continuously spot areas that require extensive cleaning.

We would always prefer the advanced Sonar Technology over vSLAM, so this round goes to the Roborock s7.

Roomba i7/i7+ vs. Roborock S7: Conclusion

Roomba is a reliable brand, and there’s no doubt that it performs excellently. But in the Roomba i7/i7+ vs. Roborock s7 comparison, the s7 is winning the game.

Its 2 cleaning modes, automatic dirt disposal system, sonic vibration technology, better battery capacity, and runtime just make it irresistible.

Paying an extra $100, as compared to the i7, for the s7 is worth every penny. Also, paying the extra $200 for the self-emptying feature doesn’t seem worth it.
