Roborock S4 vs Roborock E4

Roborock E4 vs S4: Budget Cleaners with Powerful Suction

This head-to-head Roborock E4 vs S4 comparison reveals the difference between two robotic cleaners from Xiaomi's budget line. Both of these models are universal for any floor surface, have an exceptionally powerful 5200 mAh battery that can work more than 2 hours on one charge, and have a charge & resume feature. However, as they belong to different series, these cleaners have some significant differences.

Suction and dustbin capacity

Both cleaners have variable suction, and their maximum is 2000 Pa. As for compact robotic vacuum cleaners, this level is fairly powerful. This means that the bots are able to suck in both large and tiny debris with ease.

When it comes to Roborock S4 vs E4 dustbin capacity comparison, it instantly becomes clear that the E4 has a larger one due to its bigger size. Indeed, its dustbin has a capacity of 680 ml, whereas the S4 has a 480 ml dustbin.

Using area

If you compare Roborock E4 and S4 using areas, you will notice that they have the same one: 2152 square feet. This is pretty much enough for owners of large and mid-sized houses

Noise level

The cleaners don't demonstrate a great discrepancy in the noise levels they make during the cleaning sessions. Nevertheless, the E4 appears to be a bit noisier (according to my measurements): 62.2 dB versus 56 dB. You can compare this to the level of noise made by the background music.

Carpet cleaning

The biggest difference between Roborock E4 and S4 is in their on-carpet cleaning ability. The E4 delivers stronger performance on high-pile carpets. Meanwhile, the S4 struggles to pick up the ingrained dirt from high-pile carpets and does a much better job on bare floors and low-pile carpets.
