A budget robot vacuum that navigates in straight lines and picks up debris as well as premium Roborock models but lacks the mapping and app features that come with lidar.
Where reviewers disagree: Hair tangle resistance varies: one reviewer found zero tangles with seven-inch hair while others saw significant tangling requiring scissors; Navigation around furniture: some reviewers found it efficient while others noted it bounces off chair legs and misses coverage; Deep carpet cleaning scored well in one test at 69.83% but others did not focus on this metric
Reviewers splitWhat they praise
- Navigates in efficient straight-line patterns using gyroscopes and optical sensor instead of bouncing randomly
- Picks up debris on hard floors and carpets as well as or better than more expensive Roborock models with excellent airflow
- Battery matches premium models at 5200 mAh with two and a half hours runtime on low power
- Large 640 milliliter dustbin capacity, bigger than premium S-series models
- Brushroll resists tangles well with five-inch hair strands
What they knock
- No real-time map or app features like no-go lines or room selection because it lacks lidar
- Struggles with longer seven-inch hair which tangles around the brushroll and requires manual cleaning
- Edge cleaning performance is weak with side brush scattering debris along walls
- Struggles to navigate properly underneath chairs and around chair legs

What owners single out
Buyers' weakest aspect—navigation and getting stuck repeatedly—directly overlaps the video reviewers' concern about poor navigation underneath and around furniture obstacles.
In their words
“The vacuum is not very loud. It can be programmed easily. The charge lasts for a fair amount of time. It does a good job on my ceramic floors. I have no rugs. For the price and the time cleaning that it saves me I'm happy with it. The price was very fair compared to other brands”

“Brought this unit to replace a old Roomba 610 model which I had for 5 years. I must say this unit is very disappointing compared to my old unit. I only use it on manual setting since the APP doesn't work but its infuriating that it keeps getting stuck on different locations and just keeps going back to those locations over and over so you manually have to remove it from a stuck area constantly.Its”

Frequently asked
What buyers want to know.
What is the Roborock E4 vacuum?
The Roborock E4 is a budget robot vacuum that uses gyroscopes and optical sensors to navigate in straight lines instead of random patterns. It picks up debris on hard floors and carpets as well as more expensive Roborock models.
How does the Roborock E4 navigate?
Reviewers note it navigates in efficient straight-line patterns using gyroscopes and optical sensors rather than bouncing randomly around rooms. However, it lacks lidar mapping, so it has no real-time map or app features like room selection and no-go zones.
Who is the Roborock E4 best for?
The E4 is best for buyers with clean, open floor plans who want strong pickup performance and efficient navigation without needing app-controlled software features or virtual boundaries. It is not suited for homes with many obstacles, long hair, or anyone who needs room selection and no-go zones.
How does the Roborock E4 handle hair?
Reviewers found the brushroll resists tangles well with five-inch hair strands. However, reviewers are split on seven-inch hair: one found zero tangles while others saw significant tangling that requires manual cleaning or scissors.
What are the main drawbacks of the Roborock E4?
Edge cleaning performance is weak with the side brush scattering debris along walls. It also struggles to navigate properly underneath chairs and around chair legs, and lacks app features for virtual boundaries or room selection.
How long does the Roborock E4 run on a charge?
The battery has a 5200 mAh capacity that delivers two and a half hours of runtime on low power, matching runtime found in premium Roborock models.
