How useful is the ViRobi depends ultimately on its own demands on the purity from home. The one or the other is with regular use of red Brummers (yes, he does not sing cheerfully to himself but hums somewhat loud) reduce the vacuuming. It should, however be clear that the thing can only edit larger contiguous and smooth surfaces. There's so many bad or not abfahrbare surfaces and / or carpets can also equal the rest mitsaugen.
The cleaning performance on suitable areas has its limits. Depending on the paper used etc. rings of dust and soil particles are collected up to a certain size. But as it can be described in other reviews happen that the ViRobi with a lot of dust tends to spread this again as beads. Could be avoided through frequent use.
Now a few words about the towels or rings that are required necessarily. I've actually made very good experience with the original rings of Vileda. The rings for RoboMop I whether the (still) higher price untested. Unfortunately, the Viledaringe are currently not offered by Amazon. This fall for me (Prime customer) additional delivery fee and the price is thus quite unacceptable. Unfortunately, I have also never discovered these rings in shops. To use the option, Swiffertücher or similar, I have also tested. I found the result is now not so great. On the one always has the Schnippelei, secondly, the 4 individual strips tend to slide together, or not to withdraw from the device. Another alternative are tested microfibre cloths. I have taken a suitably large cloth and it cut out a matching ring. This did much better than the strip and showed the Viledaringen least comparable dirt. I was skeptical that this ring machine washing survived (Attention micro setter always without softener). This was the case. Thus, this could be an inexpensive option for me.
