This vacuum is an amazing beast.
If you have open straight-lines with no objects in between two walls, it speeds through those areas very efficiently and in the optimum manner. It dances around objects and obstacles and goes around them to clean. It is fascinating to watch it while it does its job in rather crowded obstructed spaces. I was greatly impressed by its ability to wiggle itself in tiny spaces to clean those areas, and then come out unscathed (that, I thought, wasn't possible for a mere machine!). I had some issues in making the Android App work but support team from Roborock responded in minutes and offering to set up a private call for support (see Q&A on how to set up Mobile App & Wi-Fi Password on the Unit). 5 stars to them. What else can you expect from a few hundred dollar machine?
What I like about this vacuum are:
- Excellent Cleaning Power Both on Floor and Carpets
- Automatic Powerboost Mode on Carpet
- Very low noise that is barely noticeable. Excellent here too.
- Power and Resume Feature to cover bigger areas in a large house
- Cleans and Docks perfectly (most of the times)
- Mop attachment (that I have yet to use). Versatility!
- Very Easy to Operate and Clean
- Extra accessories supplied (filter and cleaner brushes). Very thoughtful. Awesome!
- Mobile App that builds and shows the map of the area cleaned. Superb.
- Covers big cleaning areas without any problem. Great Battery life!
- Voice Prompts & push notifications when starts cleaning and ends cleaning
I don't know about reliability part yet, but feature and performance wise this an excellent machine.
Cons and Improvements Needed
Of course, this is not perfect by all means. This being a mid price model, there are certain missing features that you need to be aware of.
- Battery life is enough for about 1000-1200 sq feet floor, but unit needs recharging for larger floor areas or carpeted area where it spends a lot more energy with carpet boost. It does mostly return back from the base to re-do remaining area, but the behavior I found is not consistent specially if for some reason unit failed to return to the base and lost the map or sensors were not clean etc. If you have a lot more area to handle, you may like to buy a vacuum with a larger battery or one which is more modern camera imaging.
- The unit like all other vacuums will not vacuum dark black or very dark colored carpets or carpets with dark blue or black borders. This is because sensors interpret non-reflection of light as "stairs" to avoid falling. I wish there was a way to disable those sensors when it is ground level and then warn before starting the robot.
- Mopping Feature is hard to use if you have a mixed floor with lots of rugs. Since there is no way to stop it from mopping on rugs without attaching magnetic boundary line markers to stop it going on those areas.
- Mobile App is good for starting and stopping the vacuum, seeing the areas covered in map, and getting alerts. I wish there was a way to create virtual boundaries and restrict to certain area of the floor only. Only way to do that is by putting obstacles or magnetic tapes to block is from going to certain areas.
If you need these features, you may be better of with the higher model.
I would definitely recommend it. Just buy it and you will be happy.

Works Great But Not With Alexa or Google Home
We've had the Robovac E20 for about a week now and have used it several times, in vacuum and in mop mode and so far we are very happy with it. In vacuum mode it took the unit 98 minutes to vacuum our 1600 sq ft home.A couple of things of note. First, this unit does not work with Alexa or Google Home. I tried for a couple of hours to no avail. I enabled the Mi Home skill and added the vacuum but nothing happened. I called Roborock after searching Google for a phone number for U.S. support. I called twice because the first person I talked to didn't explain things well and I had a hard time believing what he was telling me but when I called back I got the same answer. I was told that the Roborock does not work with Alexa or Google because these units have not been officially released in the U.S. The plan is to release them later this year and at that time they will work with Alexa and Google. The representative did suggest that I change the region in the Mi Home app (the app for Roborock) to the China server. I did that but the server could tell I wasn't in China so that didn't work and I had to switch back to the U.S. server.Anyway, I asked how I could buy one of these units on Amazon if they have not been officially released in the U.S. yet and I was told that the vendor must have purchased these units in Europe or Asia or another region and is selling them in the U.S. Not a showstopper because the vacuum still works fine and it speaks to me in English. I just wasted a couple of hours trying to connect it to Alexa and Google because the product information on the site says the vacuum works with those. It does not so don't waste your time trying to do it. I did read about some complex work arounds to get the Roborock to work with Alexa but it was way more than I wanted to get into because it involved getting into the code of the app. I'm fairly computer and tech savvy but not that savvy and like I said, the unit works fine with the app so it's not a huge deal.The second thing is the mop function. As one reviewer stated, it works better if you dampen the mop attachment completely before you send the unit to mop your floor. Otherwise it takes a while for the mop head to get damp from the tiny squirts of water that come through the water tank. I just took my hand and cupped water in it and then spread it on the mop head a couple of times until it was damp. Not soaking wet, just damp, and it worked fine.Another thing with the mop function is that the unit cannot distinguish between carpet and hard flooring when it is in the mop mode, so if you have a carpeted area or rugs, make sure you take up the rugs and block off the carpeted area before you start the unit to do the mopping. Our house has all tile flooring so it was easy for us. We do have a couple of small rugs which I took off the floor and we have a large rug between the couch and love seat which I was able to block off with a 2 x 4 on each side of the couch/love seat. It literally took me 30 seconds to get the 2x4s from the garage and just lay them down on the floor to block off the areas from the couch/love seat to the wall so the Robovac couldn't get in there and it worked great.I watched numerous YouTube videos and read a lot of reviews on various vacuum/mop units and for the price point I don't think we could have gotten a better one. It would be nice if it stored the mapping of the house and that you could customize that because then I could map around the rug for the mopping mode and wouldn't have to block it off but in the big scheme of things it's not a huge deal. For less than $300 we have a unit that does a very good job and my wife loves it so that's worth its weight in gold.
