different benefits Excellent experience with the S7 vacuum. The only aspect of the dust collector's design that I did not appreciate was how awkward it was to remove the trash. But purchasing a self-cleaning station fixed this issue, and now everything functions perfectly. Obviously, going a few weeks without cleaning is an optimistic idea, but one week should be fine. Most importantly, it is considerably more pleasant to empty the station container. With no complaints, the self-cleaning station rakes everything out of the vacuum cleaner. The dust collector is as much as possible clogged after each cleaning (1 time per day). We possess a lab. It cleans better than earlier models since hair does not wrap around the rollers. Some drawbacks include the dust collector's form, which makes it difficult to remove the trash by hand.
