The vacuum works on carpets that are low pile carpet. The vacuum's effectiveness is reduced on medium and high pile carpet types. Please see below for examples of each type of carpet.

The A10 has a HEPA filter that traps 99.97% of particles as small as 0.3 microns. This allows the sealed air filtration system to output clean air when vacuuming. Depending on how often the vacuum is used, we recommend cleaning the filter once every 6 months by removing the HEPA filter from the main body and running it under running water. Please make sure that the filter is completely dry before reinstalling back into the vacuum.
