Comparison between Roborock E4 vs S4
Design
Roborock Technology Co Ltd has completely changed the robot vacuum industry when debuting their affordable machines into the market. With precision in construction and premium quality in the engine, both models offer users easy access to home cleaning.
At first glance, Roborock models seem to have an identical construction with a basic O-shaped machine, black matte finished, and two touch buttons. However, you can easily spot that instead of going with a turret’s laser navigation like S4 robot vacuum cleaner, the E4 roborock model is adopted with the OpticEye algorithm.
The mapping method of E4 is quite efficient with dual gyroscopes and inertial mapping technology, which are used to produce internal and logical cleaning paths for different houses. And all of these technologies are grabbed inside just a tiny, little turret in front of the machine head.
Due to this, the E4 Roborock vacuum cleaner does not add up much in height and dimensions. With only 13.7 x 13.7 x 3.5 inches, this 7.7 lbs can pass through any narrow paths without even “breaking a sweat.”
You might experience some weight changes for the E4 Roborock model since it is compatible with a water tank for mopping function. If the water is filled, you’re likely to have more than just a 7.7 lbs machine.
On the flip side, the S4 robot vacuum cleaner offers users the same weight but a 2-inch higher than its counterpart. Worry not! It can still perfectly slide under most of your furniture.
As a person who has recently adapted to the minimalist lifestyle, I prefer to own a Xiaomi E4 vacuum cleaner to the S4 model. Personally, I don’t think the turret’s design is friendly when its laser navigation gives me a feeling of being checked continuously. Therefore, I will just stick with a simple, ease of use – E4 advanced robot vacuumD.
Suction Power
Not even a single debris can escape the 2000 Pa level of suction when it comes to these two robot vacuums. By generating this strong suction power, cleaning dirt dredging deep inside low-pile carpet fibers or hardwood seems not a big deal.
This strong suction of carpet boost will be given a massive advantage when E4 vs S4 are the machines that can climb up to 0.8 inches and escape the areas where other vacuum cleaners would get stuck.
Within the possible scales, the adaptive single brush of two models will repel any tangling of hair and sweep dust effectively on limited access corners. Instead of going with one brush, the Roborock E4 is equipped with an additional side brush, allowing the robot vacuum to work without interruption.
Good news to all budgeted homeowners, these brushes are removable and washable. You won’t need to spend extra money on getting new brush tools for your machine after each cleaning.
Both Roborock devices can perform well with a 2000 Pa level of suction; however, the Roborock E4 device provides more than just one type of brush. The duo brushes will wipe away more dust than its competitor’s single brush. In the end, this round’s winner is the E4 robot vacuum cleaner.
Cleaning Performance
Most people focus so much on the robot vacuum’s cleaning performance but forget that Roborock E4 is the two mopping machines as well. It has an efficient mopping capability, which can remove fine particles that vacuuming might leave behind. With a 180 ml water tank (sold separately), its gliding method will mop away those thin dust layers on the floor.
As for the vacuuming, while having a larger dustbin capacity, the Roborock E4 can only clean non-stop a 2152 square feet room. On the flip side, its counterpart’s limited cleaning area is up to 2700 square feet.
One of the features that I very like about automatic vacuum cleaners is the versatility of using APP to control everything. Not just only turning the machine on/off, you can create your own barrier, mopping/cleaning zone, virtual boundaries, route planning, timer, etc.
However, the roborock E4 does not support a virtual wall; therefore, to stop the machine from entering your undesired zones, you’ll have to put magnet strips to prevent it from intruding. The same goes with scheduling room for cleaning. While it’s impossible for the E4 robot vacuum cleaner, the S4 device can do that with just a flick of a finger.
In return, the E4 machine is equipped with a mopping attachment that Roborock S4 is missing. This is the reason why S4 vacuum cannot increase its suction level when encountering carpets.
If you want your house to have extra cleaning time, it’s time to consider the Roborock E4 mop robot vacuum. As for me, I will also choose the versatile E4 device.
Battery Life
Supersized with a 5200 mAh Lithium-Ion battery, the S4 model runtime is 20 minutes shorter than the E4 model. Using the same extra-large battery, the E4 with less advanced technology (selected zones, virtual walls, etc.) seems to eat up less battery life than its counterpart. That’s the reason why not all high-tech engines are good to use.
After continuous running, mopping, and cleaning, the drained battery of E4 will take up about 4 hours to charge completely. On the flip side, with the same battery life and material, S4 needs only 3 hours to recharge fully.
Overall, the E4 machine has longer runtime as well as a longer charging time than its competitor. Which one will you choose? Personally, I would go for the E4 model once again. Why? It would be better if you charge the device less frequently since it can affect the battery life and performance.
Noise
After doing a noise test on different levels for these two subjects, I finally concluded. The E4 machine ranges from 59-64 decibels, while the S4 vacuum cleaner’s maximum sound is 68 decibels, noisier than I expect.
You can still have a decent conversation with your friend and family while the E4 budget robot vacuum is cleaning around. And due to this, my decision has been made!
