I have my Mini wiping PLA at 140C and ABS at 170C. It works 99% of the time at those temps. I have had some problems in the past but those were due to me entering the wrong wipe and probe temps when I transferred settings to S3D and Slic3r.
It cleans really well in my experience. On the Mini, if you are having probing problems, generally, you need to manually clean the hot end and probing washers and flip or replace the wiper pad. That pad only lasts so long. The nozzle should just tap the corner washer. If you see a deflection… time to clean’er up and check your probing temps.
That said, if you are not adding conductivity based bed leveling to the Taz, I would not see any real benefit to adding the wiper.
