These Vacuum Heads were designed to fit the popular Maxi Jet 1200 series pumps

Both heads have reliefs around the top of the nozzle to help encourage water flow when cleaning in tight areas (see pictures-marked with a red circle)

It will also fit  similar pumps with a 3/4" (19 mm) outside diameter (OD) fitting

There are two heads to choose from:

Head 1 offers a bigger volume allowing you to clean up in open areas

Head 2 offers a more narrow opening allowing you to get into those hard to reach areas around the sump

Instructions:

1. Slide on the vacuum head to the 3/4" (19 mm) water inlet fitting

2. Cut a reasonable piece of tubing and attach it to the other end of the MJ 1200

3. Run the other end of the tubing into a filter sock

4. Power on the MJ 1200 and Happy Cleaning! 

Note: Maxi Jett 1200 pump is not included
