Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
A suction cleaning device for cleaning hard-to-access areas such as crevices and corners, comprising: a hollow suction tube extension for a vacuum cleaner having a slotted portion therein, said suction tube extension having an inner wall defining a suction pathway, and an outer wall; a housing attachment affixable to said hollow suction tube extension, said housing attachment having a surface cleaning mouth portion operatively communicating with said suction pathway; an extendable crevice wand operatively communicating with said suction pathway and slidably supported by said suction tube extension, said wand being movable between a first retracted position and a second extended position, said second position placing a mouth portion of said crevice wand ahead of said housing attachment, whereby said crevice wand is reachable into hard-to-access areas; and a hand-held appurtenance supported by said crevice wand and extending through said slotted portion in said suction tube extension for slidably moving said crevice wand between said first and second positions.
