Bests & Worsts Reviews from Amazon

To start this review let's get one thing out of the way: The Roborock E35 is a really good robot vacuum but is by no means the best you can get. I would give that designation to the E35's "big brother" the Roborock S50 However, the E35 is still a really good choice and offers many of the same features, quality, and cleaning efficiency as the S50 but with a few major exceptions. First let's talk about what the E35 does well. Probably the most important factor for a vacuum of any kind is suction. The E35 has class leading suction in not only the budget robot vacuum category but for all vacuums. The 2000pa motor is the same that can be found on the S50 and preforms equally well. Each run I am astonished at how much dirt and debris the E35 comes back in it's dust bin. And speaking of dust bin the E35 actually has a very large dust bin which is quite a bit larger than the S50's. It is very nice to not have to empy the dust bin on the E35 after each run The second impressive quality of the E35 is battery life. Again like the S50 the E35 comes with the same 5200Mah lithium ion battery which provides long run times and I believe is probably class leading for robot vacuums. My E35 has been able to run for 90 minutes or more on a single charge. Now for the quality that separates the E35 from many of it's other budget vacuum competitors: Navigation. Unlike many budget robot vacuums that bump and ping pong randomly across the room and never seem to be able to vacuum over every spot, the E35 has an advanced sensor system coupled with a complex algorithm that helps it navigate floor plans in a back and forth motion and is very similar to the system used by robot vacuums like the S50 that utilizes a lidar navigation system. Instead of bumping into a wall and bouning away in an odd angle like "pong" the E35 runs a straight path,finds an edge, then shifts a few inches, and comes right back. It almost reminds me of mowing a yard but instead of the yard it's carpet! Speaking of which I had read that some vac's have trouble with brushing carpet but not the E35! It leaves fresh brushed carpet lines and almost make you not want to walk across the floor and mess it all up. The E35 also offers app integration and can be controlled through the app with wifi connectivity. From the app you can schedule cleaning times, check on maintenance, and it will even allow you to view a generated map of your home and past cleanings. So what keeps the E35 from the top of the mountain? Navigation. While as I previously mentioned it does navigate much better than most robot vacuums it still cannot compete with robots that use Lidar navigation systems. Lidar allows robots like S50 to create a much more detailed and accurate map of your home. Then it allows users to set "no go" lines and zones to keep the robot from certain areas. It also allows users to vacuum only certain areas in a zone clean. The E35 simply cannot do that and because of this limitation it opens up the possibilty of it going places that it shouldn't or getting stuck more often. So what is the bottom line. The E35 is a very good quality made robot vacuum that cleans, navigates, and performs almost as well as the top robotic vacuums. I think it is a very good choice for those on a limited budget or not willing to shell out $500- $1000 for a flagship.. As the title of this review spells out the E35 is a mid tier robot vacuum that bridges the gap between poor quality cheap budget vacuums and flagship robot vacuums. If you want a quality robot that cleans and navigates well the E35 is a solid choice. I'm giving this vacuum a 5 star review because even though it is not the best overall robot vacuum I believe it is the best of the robot vacuums without a lidar navigation system on the market If you can't afford those vacuums with lidar the E35 is the vacuum for you!
