When my wife asked me, but to get her times as a part, I have no idea how many times a good piece would be used. It does not replace a reasonable vacuum cleaner and wipe to get around not around it, but in between the thing is great. Super would be if they still could wean the annoying sound the part, but that's life. Who puts the Swivel regularly to the wall socket, has gained a patent assistants. Tip ... never about carpet fringe drive, or something of that nature.
Conclusion: If you have, when smooth floors are available.
