This machine does a great job. Easy to fill clean water canister and empty dirty water canister. Canister is not that big so when dirty water canister is full machine shuts off. So with a big area you might have to empty dirty water 3 or more time's. But easy to do. Love the roller cleaning feature when you set it back on the base to be re charged push the button and it cleans the roller for you. Great machine #sweepstakes
