Pool Central Aluminum Weighted In-Ground Gunite Swimming Pool Vacuum Head on Wheels 17.5" -

After limited use, this seems to be a top-notch vacuum. It rolls and brushes as it goes so it counteracts the shortcomings of a brush vacuum that's hard to push and a rolling vac that can't pick up things that cling to the bottom. It's heavy, but under most circumstances, that's a good thing. There are two squeegee strips on either side of the brush. I'm not sure what purpose they serve, and one detached itself several times at first before I pushed it in as far as it would go. All in all, this seems to be a very good value, well made, and it vacuums a fairly wide swath.
