CONCLUSION

   For an “entry-level” model the 850T robot vacuum cleaner by Proscenic actually performed very well during my tests. Suction power is very good (although it doesn’t feel as 3000Pa, more like 2500Pa), battery life exceeded 150 minutes at quiet mode (remember, i don’t have any carpets in the lab which should require more power and thus battery life should drop faster) and as for covered area the 850T is the 2nd best model in the charts (currently anyways). Unfortunately, the gyroscope navigation is not very accurate and so aside bumping on most things in its path (which some people may not like) the 850T also doesn’t share the same map features (virtual wall/restricted area/editors) one can use from the app as with LDS models. The addition of a 1 meter long magnetic tape may help in some situations but it’s nowhere near as effective.

   Proscenic currently sells the 850T robot vacuum cleaner for just USD238 inside the USA (Amazon.com) and for 239Euros inside the EU (Amazon.de) a price tag which is quite balanced for what you’re getting. Still even though I found no issues with the 850T the fact that it bumps on everything in its path (just like every other robot vacuum using a gyroscope navigation system) means that I strongly recommend getting an LDS model instead (like the M6 Pro). If, however spending more on a robot vacuum cleaner is not possible for you then the 850T certainly deserves checking out.
