UPDATE:

I sent the same text directly through the app. According to technical support, the problem has been identified and they will send a solution as soon as possible.

Until then, I think I'll be left with the robot running around and vacuuming poorly...

Thank you for your update. Keep us posted if the problem got resolved!

Solution What should I do if the RV20 Series Robot Vacuum keeps spinning during cleaning?

BIG NEWS

I've just received the new firmware update for version: 1.1.3 Build 240318 Rel.161138

Wish me luck and I'll share the feedback soon

  @Johnny-5 

I made the request for help directly through the app:Settings ->Help and Feedback

I explained what was happening, shared the report and technical support in Portugal contacted me via email. The firmware appeared in the app, it seems that support has the ability to "release" new firmwares.

I believe that this is not the "final firmware" and is just an emergency solution and that a version with more improvements will be released in a short time.

As I'm a beta tester for the app and I've sent several requests for feedback, this may have speeded up the process.

The robot's erratic behaviour happened on marble floors, wood and carpets. With the lights on or completely in the dark.

I hope I've helped

  @nevesd5 How did they provide the firmware update to you? Our RV20 is still on Firmware version 1.1.3 build 240103 Rel. 150809, and there is no update available. Do you happen to have a dark floor, and is the Hall a dark environment?

Here's a new update of version 1.1.3 Build 240318 Rel.161138, now with more than a month of daily use.

Whenever it vacuums, the robot spins on itselfeven in areas without obstacles (it seems that it has to "look around" to know where it is). Interestingly, these turns no longer appear on the map, only straight lines. Work of the programmers :) Example: The robot goes in a straight line. It stops, rotates 360 degrees and continues in a straight line again. It doesn't get lost.

Vacuuming is quite fast, although 3 or 4 times it has changed the direction of the cleaning pattern. Maybe I was tired of always vacuuming the same way.

Another issue is hitting some objects that are always in the same place, cupboards, plant pots... Sometimes it stops before, sometimes it goes around and sometimes it hits at full speed.

Another thing, and I may be being a bit meticulous, but when climbing onto a carpet the robot takes a few seconds to increase its suction capacity and sometimes it's already halfway across the carpet when it revs up the motor. Even if you increase the carpet detection sensitivity, the behavior is the same. In this case, if the sensitivity is increased, the robot accelerates the motor in places without carpets. In other words, halfway through the carpet the cleaning isn't as powerful.

But so far the balance is very positive, but improvements are always possible.
