Query: Don't waste your money

I've had this products for a little over a year, and never have been able to get it to work properly. The spray mechanism is worthless, and we right off the bat wound up having to use a separate spray bottle. At the start, the suction portion (and yes, contrary to other reviewers' suggestions, we did have it correctly positioned for the job) would only pull back up less than a quarter of the solution put down. After a while it stopped suctioning anything up at all. The suction port quickly clogged with debris, and is impossible to clean, because the clear plastic shield is not removable. The rotating brushes aren't too difficult to remove, clean and replace ... but that is about the only plus to the thing.The machine is not worth the money spent, I'm sorry to say. Another life lesson learned.
