Operates as intended

Functions as it should. Extras space added because they want more words for a review

Excellent product

Great quality. You get what you paid for. Reduces cleaning time because of the power and GPM.

Powerful machine

Decent machine for the money, pair it with a turbo tip and it will get past the dirt!
