Decided to refinish the hardwoods in my bedroom before repainting they walls (600 sq ft, roughly). Loads of damage from the last decades and not proper care with prior owners. All walk-behind sanders were rented out at all stores near me so I took a chance and went for this one based off sale price and an even split of reviews pos/neg. This little thing has power! The dust bag sucks but I connected my shop vac to the back and that helped tremendously. It’s time consuming given the machine for use in a decent sized room, but it did the job well. I went with 36>60>80 grit sequence and it was perfect. Bought a 5-pack of each grit paper and used 3 of the 36 & 60, 2 of the 80 (mainly cause of my pickiness but 1 would’ve been enough). Photos are the before and afters - you can see the damage I was working with; so bad! I purchased this house knowing it was a fixer upper and my room had the floors of the house with the damage. Overall I would recommend this for smaller rooms and projects if you don’t mind the workout - it served its purpose really greatly much to my surprise. I’m happy with my purchase and now have added a new Ryobi tool to my growing collection. \m/
