Compact and lightweight, Miele's S4 Galaxy Series Vacuum Cleaners are easy to use and quiet! The entry-level S4212 Polaris and Neptune vacuum cleaners come complete with a Super Air Clean Filter, manual power controls on the canister, three professional grade accessory tools and more. The Super Air Clean Filter can be replaced with a HEPA Filter (sold separately) if desired. Color and the type of standard floor tool are what separate the Polaris and Neptune from each other. The light blue Polaris comes standard with a combination floor tool and can be upgrade to our Deluxe or Supreme package to include additional floor tools to accommodate highly polished bare floors and low-medium pile carpets. The turquoise Neptune comes standard with a parquet floor brush and air-driven turbo brush for highly polished bare floors and low-medium pile carpets. This vacuum is amazing! My rugs look as clean as they did when I first bought them 3 years ago! The vacuum has an active air filter too so it cleans the air while cleaning my floors! My house has leveler windows that do not keep the dirt out so there is always dust in my home. But this vacuum has helped so much that I feel like I moved into a new home. The quality is unmatched.
