Got the machine, and yes had to screw it together (easy). Used it yesterday and what a surprise.
I have a townhouse and it is light enough to carry upstairs.
Very easy to fill with water and product.
Does a GREAT job cleaning!!
Very easy to empty tank.
Easy to clean, as parts are removable.
I recently purchased this product and am perfectly happy with it. We have 3 dogs who make the high traffic areas in our house a challenge. This product is light-weight, and effective for regular cleanings and pet accidents. I would use a larger machine for a bi-annual cleaning. For the price and size of the machine it's worth the investment!
