V 36.13: Software Behavior Earlier and Now- Interesting Information!
I am new here, so let me start with some background that covers my PUREi9 usage:
I can easily see changes in software and how it affects performance since I have a rather big apartment- 192 sqr meters (2067 sqr feet) in total. So if I remove the entrance, balcony, laundry room, 3 bathrooms, and 2 storerooms. Then we have bed platforms in three of the bedrooms- so that are additional areas that the robot doesn't need to clean. The robot reports that the area that is cleaned is 80 to 90 sqr meters. Same area but a different number of sqr meters are reported each time (interesting!) This area to clean is divided into 9 rooms.
I have 1Gbps fiber optics internet connection and the WiFi system I am using is Netgear Orbi RBR50- 1 base station and 3 satellites, covers the whole apartment and no weak signal spots.
We have hardwood flooring in all rooms and no carpets.
My way of measuring if the cleaning is good or not is simple, yet very effective! I live in Singapore and in this humid tropical climate, so we always walk barefoot at home. If there is any dirt on the floors it will stick to the feet and when I take my evening shower and put my feet on the wet white tile floor, I can see my footprints on a scale going from nothing to different shades of grey and to almost black. Simple but a true measurement of cleanliness. :-)
I bought the PUREi9 on the 10th of November last year and it worked rather well! But I quickly realized that the cleaning was NOT done in a smart organized way but more of a non-logical way! It starts with one room and before that room is completely cleaned it leaves for another room. Then wasting battery power by later coming back to the rooms which still have small patches left to clean. But I was not concerned about it since the robot cleaned the apartment in two rounds- so only one recharge.
But recently the behavior of the robot has drastically changed! Since there is a bug in the App software I can't check when the last software upgrade happened, but now I have version 36.13.
Sorry, but let me be honest and straight forward here. Version 36.13 is a nightmare and my robot has totally "changed its personality" and I can hardly believe this is the same robot vacuum cleaner I bought 5 months ago!!!
First of all, I only get about 1 good (good, but not great!) cleaning out of 4- 5 cleanings. The robot goes from room to room without actually finishing any of the rooms. Then wasting battery power by going back to clean small leftover spots in rooms which are up to 15 meters away!
It now also frequently bounces off the furniture and try to go under places which didn't try earlier. So the plastics are all scratched up. My apartment can, as we have seen earlier, get properly cleaned in 2 rounds- one recharge. But now it can go on from early morning to evening and still can't finish the apartment! The record at the moment is 5 recharges!!! After that, we just stopped the robot's "crazy cleaning tour"! Then when I checked the status between each recharge I realized that the robot could spend one whole battery charge on cleaning less than 1 sqr meter up to only 5- 6 sqr meters!!! Something is obviously seriously wrong with the navigation system!
But that's not all! Many times it can "lose a whole wall"! You can see it all in these screen captures:
Then yesterday what should never happen did for sure happen- the robot fell down the staircase to our entrance area!!!
Then now very often it can't find its way Home! And ends up in some corner with the battery dead! After that when fully charged- it has no idea what happened and will start from the very beginning! :-(
So there is no question about it- the current software is a low-performance navigation system and in my personal opinion rather useless. I sincerely hope that you guys at Electrolux realize that by releasing buggy low-performance software upgrades, you are slowly but very effectively killing the sales of your PUREi9!!! First of all, I have seen several reviews online which highlights your robot's strange navigation behavior. Then I personally had to protect myself and call around to the people I recommended to buy PUREi9 to tell them to hold on for a while and not buy now! Otherwise, they will blame me for buying a "crazy robot"!
You have a great product (mechanically only at this moment) which has gone from great to bad because of software updates which has step by step lowered the performance to unacceptable levels. If you could get your internal software upgrade process in order and start to release software upgrades which each time increases the performance of the PUREi9, I gurantee that you will soon find Electrolux in a Google Search for "the best robot vacuum cleaner".
P.S. I have a 9 minutes long video of PUREi9 bouncing back and forth between the legs of a chair, footstool and a table, totally lost, before it finally finds its way home. I can send it to you if you need?
