I bought this so I could easily vacuum and mop all of my floors at the same time. I love the lights on the vac as  I can easily see all of the pet hair on my floors. However, every time I use the mop, after I am done, all of the liquid slowly leaks out when not in use. I end up with a huge puddle on the floor and have to refill the solution. It is very expensive and frustrating, so I have stopped putting any solution in and just using the vacuum.
