What kind of sweeping robot is the most practical? 3 well-known brand comparison evaluation

I didn’t want to clean, so someone invented the vacuum cleaner. Then I didn’t even have to think about it anymore — they developed a sweeping robot. As a lazy person, I’ve tried many different models, but most of them still ended up bumping into walls and getting stuck in corners, looking quite frustrated. The dust on the floor was more than just visible — it looked like a cloud of particles floating around.

Of course, with technological advancements, today’s sweeping robots can now clean a house much more effectively. However, despite their appearance, they often leave behind allergens such as pollen, mold, and pet hair trapped in cracks and carpets. These tiny particles are hard to remove completely, which is why some models still fall short in real-world performance.

Recently, the media tested three of the most popular sweeping robots on the market: the Dyson 360 Eye, iRobot 980, and Cowbot DR95. They designed a series of challenges to evaluate their suction power, filtration efficiency, and climbing abilities. Here's what we found.

Part 1: Suction Test

In the suction test, four different levels were evaluated to assess how well each robot handled various cleaning scenarios.

Level 1: Carpet Suction Test

When faced with soda powder spread over a carpet, all three robots showed some level of suction. The Dyson 360 Eye was the fastest and cleaned the best. The iRobot 980 also performed well but needed multiple passes, making it slower overall. The Cowbot DR95 struggled with suction and required more effort to clean the same area.

Level 2: Gap Test

This time, the challenge increased — the gap between the floorboards was 0.5 cm wide. The Dyson 360 Eye, equipped with a powerful 78,000 rpm motor, easily sucked up the powder. The iRobot 980 came second, while the Cowbot DR95 still had room for improvement.

Level 3: Mesh Fabric Test

What if there was a layer of mesh fabric over the gap? In this upgraded test, the Dyson 360 Eye still managed to suck up the powder cleanly, while the Cowbot DR95 outperformed the iRobot 980.

Level 4: Micropowder Test

For the final test, fine powder (0.3 microns) was sprinkled on the floor. At first glance, all three robots seemed to do a good job, but under a microscope and UV light, the Dyson 360 Eye stood out — it left almost no residue. The iRobot 980 had visible traces, and the Cowbot DR95 showed smear-like deposits that needed improvement.

Part 2: Filtration Test

Secondary pollution is a common issue many people overlook when using a robotic vacuum. This part of the test focused on how well each robot could filter out dust and prevent it from being released back into the air.

Level 1: Color Test

All three robots were fitted with new filters, and then colored powder was suctioned. The Dyson 360 Eye performed the best, barely lifting any color powder. The iRobot 980 and Cowbot DR95 both raised a significant amount of powder, indicating less effective filtration. After the test, the Dyson filter was the lightest, followed by the iRobot 980. The Cowbot DR95 filter was the most stained.

The Cowbot DR95 uses a double-layer filter system, which improves filtration through physical separation. However, it still struggles with complete dust containment, leading to secondary pollution. The iRobot 980 features a triple filtration system, capturing more allergens and small particles. Dyson’s cyclonic technology separates large and small dust particles efficiently, minimizing the risk of recontamination.

Level 2: Gas Test

For the gas test, cigarette smoke was used in a sealed box. The iRobot 980 let out a lot of smoke, while the Cowbot DR95 released it slowly, like a humidifier. The Dyson 360 Eye, however, kept the smoke inside, showing superior filtration.

Part 3: Climbing Test

The final test evaluated the robots' ability to climb over obstacles.

Level 1: Stair Test

The iRobot 980 and Cowbot DR95, with their roller-based designs, could easily climb the first step but struggled with the second. The iRobot 980 got stuck halfway, while the Cowbot DR95 turned around. The Dyson 360 Eye, with its tracked design, successfully climbed both steps.

Level 2: Obstacle Test

Equipped with different navigation systems, the robots faced a bowling alley setup. The iRobot 980 and Cowbot DR95 knocked over some pins, while the Dyson 360 Eye avoided them with ease thanks to its panoramic camera and SLAM mapping technology.

After completing these rigorous tests, it's clear that the Dyson 360 Eye outperformed the others in most categories. If you're looking for a smart, efficient, and reliable sweeping robot, the Dyson 360 Eye is definitely worth considering. Choose the one that fits your needs and lifestyle best!
