Roborock E4 Review

Introduction to the Roborock E4

The Roborock E4 is a robot vacuum designed to deliver reliable, hands-free cleaning for homes up to 1,500 square feet. With powerful suction, efficient navigation, and simple app controls, it tackles dirt, dust, and pet hair across hard floors and low-pile carpets. Its straightforward setup and robust build make it an excellent entry point into automated floor maintenance.

Equipped with a large dustbin and long-lasting battery, the E4 focuses on performance and value. It combines systematic cleaning patterns with obstacle avoidance to ensure comprehensive coverage, while its quiet operation means you won’t be disturbed during cleaning cycles.

Key Features of the Roborock E4

1. 2,000 Pa High-Efficiency Suction
   Delivers strong airflow to lift dust, crumbs, and pet hair. The dual-layer filter captures fine particles and helps maintain suction over time.

2. Gyroscope-Assisted Systematic Navigation
   Uses onboard gyroscopes and optical sensors to map your home in real time. The E4 follows a row-by-row cleaning pattern, minimizing missed spots and reducing overlap.

3. Large 640 ml Dustbin
   Holds more debris than many competitors in its class, so you can go longer between empties—ideal for larger apartments and homes with shedding pets.

4. Edge-Sweep Brush Design
   Dual side brushes sweep debris along walls and into the vacuum’s path, ensuring corners and edges are cleaned effectively without manual intervention.

5. Automatic Recharge & Resume
   When battery levels fall below 20 percent, the E4 returns to its charging dock. Once recharged, it picks up exactly where it left off to complete unfinished areas.

6. Quiet Operation
   Operates at around 60 dB in standard mode, allowing daytime or evening cleaning without disrupting conversations or work.

7. App Control & Scheduling
   The Roborock app lets you set cleaning schedules, select suction modes (Quiet, Balanced, Turbo, Max), and monitor cleaning history. Basic voice control via Alexa and Google Assistant is also supported.

Performance and Efficiency

In practical tests, the E4 methodically covers floor space, often cleaning a 1,000-square-foot area in under an hour on Balanced mode. Its 2,000 Pa suction power handles everyday debris—including cereal, pet kibble, and dust—with ease. While not equipped with Carpet Boost, it still picks up 90 percent of debris on low-pile rugs in a single pass. The systematic row-by-row pattern avoids the “random bump-and-turn” approach, resulting in more predictable and faster cleaning cycles.

Obstacle detection sensors prevent the E4 from crashing into furniture. It gracefully slows before contact, then negotiates around legs and low obstacles. The onboard cliff sensors ensure it won’t fall down stairs or ledges.

Battery Life and Charging

Powered by a 5,200 mAh lithium-ion battery, the Roborock E4 can run up to 200 minutes in Quiet mode—enough to clean most medium-sized homes in one session. In Max suction mode, runtime decreases to about 100 minutes, still ample for thorough cleaning. A full recharge takes around 4 hours. Thanks to its auto-resume feature, the E4 can finish large floor plans across multiple charge cycles without user intervention.

Pros of the Roborock E4

• Strong Suction: 2,000 Pa tackles dirt and pet hair effectively.

• Systematic Navigation: Row-by-row cleaning reduces missed areas.

• Large Dustbin: 640 ml capacity for less frequent emptying.

• Long Runtime: Up to 200 minutes on a single charge.

• Quiet Operation: Suitable for use during work or rest hours.

• Simple App & Voice Control: Easy scheduling and basic voice commands.

Cons of the Roborock E4

• No Carpet Boost: Suction does not automatically increase on rugs.

• Vacuum-Only: Lacks mopping function for wet spill cleanup.

• Basic Mapping: Cannot store multiple floor plans or set no-go zones.

• Manual Dustbin Emptying: No self-empty base option.

How to Get the Most Out of Your Roborock E4

1. Allow Initial Mapping Runs: Let the E4 complete one full cleaning cycle uninterrupted so it learns your floor layout.

2. Choose Suction Modes by Room: Use Quiet mode in bedrooms and Max mode in high-traffic areas to balance noise and cleaning power.

3. Empty the Dustbin Regularly: After heavy-debris runs or weekly, to sustain peak suction performance.

4. Keep Brushes and Sensors Clean: Remove hair from side brushes and wipe cliff sensors monthly to prevent navigation errors.

Conclusion

The Roborock E4 offers an outstanding combination of performance, runtime, and affordability. Its powerful suction and systematic navigation deliver reliable cleaning across both hard floors and low-pile carpet. While it omits advanced features like Carpet Boost, mopping, or multi-level mapping, the E4 remains a compelling choice for those seeking a straightforward, no-fuss robot vacuum that gets the job done.
