Water Tech Pool Blaster Max Battery Powered Pool and Spa Cleaner
The most versatile vacuum here that will work on virtually any pool surface from concrete to vinyl, that's what makes the Water Tech Pool Blaster Max #1 on this list. It's lightweight at about 5 pounds, and gets even lighter once under water. The rechargeable battery lasts over an hour of run time, which should be enough time to clean virtually any pool. The easy rinse collection bag makes cleaning painless, and it will suck up just about anything that it comes into contact with beneath the water, and that includes algae. Attach it to the end of a pool pole and get to work.
