We couldn't be happier to add the new D1 model to our assortment of quality, top-rated vacuum cleaners. Sebo is known for their reliability, longevity and value price and they have certainly proven that again with this new addition. The full-size Sebo D1 with all it's features makes this an exceptional vacuum for it's price. It's tightly sealed hospital-grade filtration system also wins over our Allergy and Asthma experts making this a top choice. The D1 is perfect for homes which have primarily hard surfaces with an occasional low pile area rug. We do not recommend this for households that contain lots of carpeting as it does not have, nor can it be upgraded to use a motorized power head with a beater bar for more enhanced, deep carpet cleaning. One thing is certain still, this powerful, ultra-quiet vacuum will provide years of reliable use, without breaking the bank.
