Roomba i4 vs i6: High Suction Vacuums

Roomba i4 vs Roomba i6: Higher Suction Pressure vs Non-tangle Brush

Testing to see if the Roomba i4 is a match for the newer Roomba i6 showed the i6 to be the better cleaning robot with higher suction pressure, more bin capacity, and quieter noise. However, pet hair handling is better in the Roomba i4 vs i6, thanks to the non-tangle design of its brushes.

Suction and dustbin capacity

There is a significant difference between the Roomba i4 versus the i6. The Roomba i6, with a suction power of 1700 Pa, is more effective in picking up dirt and unwanted particles off the ground. The i4 with 900 Pa suction power is far behind the i6 in this category, almost halfway behind the former.

Having a big dustbin is a plus in vacuum cleaners. If you place dustbin capacity as a rationale in choosing the better product between the i6 vs i4 Roomba, the former should be your choice. The i6 has a bigger dustbin capacity than the two products, with 500ml against 400ml of the i4.

Using area

I have always been a fan of iRobots with the capability of covering a large area. The difference between Roomba i4 and i6 in this category is non-existent due to their similarity. These two robots offer excellent maneuverability and range limited by how long their 1800 mAh batteries last.

Noise level

One main reason people use Roomba vacuums is their low-noise feature. Testing the Roomba robots shows that the machine's cleaning sound is as loud as a casual conversation.

I conducted multiple tests on the iRobot Roomba i4 vs i6 robots, showing that i6 has the lowest noise. It has a noise level of 65 dB, which is quieter than the 70 dB on the i4.

Carpet cleaning

Like many other Roomba products, you can count on the products under review to effectively clean your carpets. However, they only suit medium and low-pile carpets and bare floors. In this Roomba i6 vs i4 category, the carpet cleaning of the i4 is no match for the capability of the i6. Since the i6 has high suction, it is no surprise that it outperforms the i4 in repeated tests in the iRobot i6 vs i4 comparison.
