They are a little bigger than the bissell pads that came with my spin wave and i was worried they wouldn't fit but they fit great and work great . I have laminate and tile on the floor. I would buy again. I also bought an AirX RX 101 cleaner, which gets rid of all the streaks I've had with other cleaners and other pads. I do NOT add purifiers directly to Spin-Wave for fear that the solution might interfere with how Spin-Wave works. I mix the concentrate as instructed on the AirX RX 101 bottle, lightly spray onto the floor and then use Spin-Wave.
