The Tristar KR-2156 is a handheld vacuum suitable for dry and wet dirt. Don't consider it as a substitute for vacuum cleaning jobs, since the voltage of 7.2 volts is too limited. However, it's very suitable for sucking up breadcrumbs or for getting into the small corners you can't get to with the regular vacuum. The cordless hand vacuum has 3 attachments; 1 for chinks, 1 for furniture, and 1 for wet dirt. After use, simply hang it up on the wall mount where it charges itself. Is the handheld vacuum losing suction? Simply wash the filters under the faucet.
