Vaccuum
Does not work well on deeper pile carpeting.
Does not have an adjustment to raise or lower the beater bar . Good on hardwood floors or tile.

Great customer service.
Glad I bought the protection. The vaccume worked great for a while then quit holding a charge. They refunded my purchase price (Amazon gift card).
