A review is of interest because not as many Powerbot owners reporting compared to more famous robotics brands.
The original 9250 (first WiFi model) -- not the newer "R" version -- does not have the mapping report which was introduced in the later more expensive 9350 with "select a room" (requiring such info). Samsung has a peculiar wide array of models with different features and prices, so only the manual would specify whether the app has a feature. The R9250 may differ from the original in using mag strip boundary markers instead of IR Virtual Guards (at least in U.S. distribution compared to European), and might have counter weights in the front -- would have to check the marketing material (you can see any counter weights shining a flashlight through the front).
I do not see any use for the map history feature apart from idle curiosity. To really tell how it is working I think it must be observed in action, for interaction with furniture etc. I am skeptical of the value of all the WiFi stuff as far as cleaning goes. It is a pretty expensive toy for minimal screen entertainment -- just an opinion. The marketers have obviously seen WiFi throughout the industry as a valuable option.
It is interesting you find the 9000 behavior more attractive than the latest 7000 series behavior, in the smaller size and the odd intake shutter. The original 9250 proved susceptible to traps against furniture legs well cured with two modifications, shown in the 9000 thread, disabling the wheel extension sensor and expanding the side bumper. It works very well with these corrections over hundreds of cleaning runs now. Thread
http://www.robotreviews.com/chat/viewtopic.php?f=22&t=19388I got the WiFi model only for possible software improvements in updates. It has been updated 3-4 times (up to RV0.0.53 now) with no additions to behavior, such as 3-times corner poking mentioned on the 9350, but never supplied (not to mention select-a-room). I suspect updates are only for WiFi aspects itself, app features and complexities of WiFi tech itself, protocols and what not --
Amazon Alexa... The App screens have just been modernized a bit with more standard formats used in the industry. With the first WiFi model, of course, it was not possible to anticipate the marketing policies of the company. They have since added WiFi to cheaper models in the series, pursuing this perceived marketing advantage, equally sought by other brands.
The most obvious software fault they could have fixed, insufficient interpretation of wheel extension sensors for picking up off the floor, causing unnecessary furniture leg traps, was never fixed. More money in WiFi apps I suppose. One report posted seems to describe a similar fault remaining the new 7000 series. Fortunately that sensor can be easily disabled in absence of a proper software fix (notice Neato robots have such sensors and never exhibit this kind of trap shut down -- proper software, like checking both sensors etc.).
