Roborock E4 Robot Vacuum Cleaner Black (E452-00)

Methodical Cleaning Perfection
Clean your floors more effectively and efficiently with Roborock E4. Every movement it makes is precisely monitored by a suite of precision sensors. Combined with an internal map of walls and obstacles it encounters, it knows where it has been and what is left to clean. It moves up to 10% faster1, while an 11% increase3 in suction and double the battery power delivers deeper, longer-lasting cleaning. Combine suction with mopping2 to eliminate the fine dirt that other vacuums may miss. Use the app to set detailed schedules for different days and even suction levels

Fast and Logical
Using gyroscopes, OpticEyeTM motion tracking, and a bumper, E4 closely tracks its movements, edges of rooms, and obstacles. It knows where it has been, and can calculate where it needs to go. Because it moves up to 10% faster1, it finishes cleaning quicker.

Dual gyroscopes
Onboard gyroscopes monitor minute changes in the angle of motion and recognize if the robot has been flipped.

Internal route plan
Gyroscope and motion tracking data combine to create an internal map used to create logical cleaning paths.

Serious suction
Strong suction is great for lifting grime off floors and critical for dragging it out of carpets. That is why E4's suction is 11% stronger3 maxing out at 2000Pa4. Expert airflow engineering, streamlined ducts, and a bell-shaped high static pressure zone keep suction consistently powerful throughout the clean.

More than a Vacuum
Make your floors shine and remove fine particles that other vacuums may leave behind with the easily attached mop2. Now 28% larger1, the upgraded E4 mopping system2 uses innovative hydraulics to let you adjust the water flow to meet different cleaning preferences.

Clean Deeper and Further
Able to climb up to 2cm (0.8in)5, E4 roams smoothly around the home, over thresholds and carpets. At the same time, a 100% larger3 5200mAh battery gives it the energy to vacuum up to 200sqm (2152sqft) on a single charge6.

Harsh on Hair
Anti-tangle main brush, side brush, and omnidirectional front-wheel resist tangles better, keeping E4 cleaning without interruption.

Handle Larger Homes
Extremely large homes can be cleaned effortlessly using Auto Top-Up. E4 knows if it hasn't finished a job so if the battery runs low it will return to the dock for a top-up charge and continue where it left off.

Everything in an App
Your phones is all you need for control. Start cleaning from anywhere, set schedules, choose cleanup modes, check on cleaning progress in real-time, and more. After a cleanup, review a completed map to make sure E4 has covered your entire home.
