Don’t need digital mapping: If you want straighter navigation when cleaning, but don’t really need the digital mapping, the E4 fits the bill.

Roborock E4 Review | Tested by GearLab

Efficient navigation: Even without LIDAR, the E4 will navigate efficiently, even around cramped spaces around chairs. It’s the cheaper version of the Ultra series since it uses the older twin-barrel base station of the previous generation S7. Bagged systems are excellent because it keeps things tidy, and disposal is straightforward – pull out the bag and throw it in a trash bin. Some of them calculate how much power they need to finish cleaning, others recharge up to 80% and then resume. It is easy to set up, easy to use, and effectively cleans all floor types and debris types we tested.The Roborock S6 MaxV is the first in the lineup with a dual camera that works in tandem with a powerful Qualcomm processor to recognize objects on the robot's way, calculate their size, and avoid them. Overall, LIDAR sensors are more precise with location tracking, helping Roborock products traverse around tight quarters (generally) better than any Roomba intelligent robot vacuum.

When it came to cereal, it broke the larger pieces down and left most of it behind on shorter carpet.

Every Roborock comes with a precise navigation system, from the motion tracking navigation in the E series, PreciSense® LiDAR navigation in the Q and S series, and ReactiveAI 2. The S6 MaxV will be able cords to avoid to a certain extent, but it still tangles up with stretched cables out of its line of vision. The Q series is the rich-featured robot vacuums with a self-emptying dock th It has an XL mopping reservoir and good suction, especially good on hardwoods — 91% debris removal overall. The live map shows the robot’s location in real time as it vacuums with grid lines indicating areas it has cleaned.The Roomba 675 is better at cleaning all floor types, especially carpet, but lacks recharge and resume, doesn’t mop, and doesn’t digitally map. During our cleaning tests, it performed just as well as any other models in the i Series—99% debris removal overall. The E4 is no exception, as the round shape, rapid spinning brush, and navigation hamper it from cleaning this area. It’s got high airflow rivaling high-end robots, but the navigation, I feel, lacks thoroughness, which hurts it somewhat in the cleaning tests. Consumers can set multiple “invisible walls” around the map to block the robot from select areas, and the app is accurate at this task.

If I had to pick one between those 2 models I would opt for the Roborock S65, due to its improved navigation. The entry-level 600 and E-series robots are the most basic options with IR-based navigation that pinballs in randomly.

This feature is only available in the J7 series since it’s the only model with a front-facing camera. The bumper allows the E4 to gently bump into obstacles and change directions without damaging the vacuum or the object in the way. On high carpet, the results continued to be surprisingly good, capturing 98% of all debris that was tested. Also, the S5 Max has greater suction and can charge up in the middle of a cleaning cycle and then resume cleaning.
