Suction Cleaner
Close
You have a “suction cleaner” with a water hose that comes out of the top of the cleaner and plugs into the skimmer or pool wall, similar to those pictured below.
Customers report that in some cases, two clips installed in a “plus” pattern on each drain cover is needed because of the variables involved in the particular application.
Below are a few examples of suction cleaners.
Robotic Cleaner
Close
There are a wide variety of main drain covers and robotic cleaners in use today, and many possible combinations of drain covers and robotic cleaners.
Main Drain Clip-On has had mixed success preventing “robotic” cleaners from getting stuck on the main drain cover. With two clips installed on each drain cover some customers report that the clips prevent the “robot cleaner” from getting stuck, however, other customers say that the robot cleaner still gets stuck from time to time. Some customers report that the clips make the situation worse.
Even though we have a low return rate, Main Drain Clip-On makes it a policy to let customers with “robotic” cleaners know about our results.
Main Drain Clip-On recommends that you use two clips installed in a “plus” pattern on each drain cover because the clips are only ¾ inch wide, and the intake slots for many of the robotic cleaners is wider than ¾ inch and can cause the cleaner to hang up on the clip.Below are a few examples of robotic cleaners.
Style "A" Drain Covers
Close
The D1 clip fits main drain covers similar to the Style "A" pictured above. Depending on the drain cover manufacturer, the distance between the holes on the drain varies from 6-0” inches to 6-5/8” inches.
If the distance between the holes on your drain is from 6-0" to 6-3/8" apart, the D1 SMALL clip will fit. If the distance between the holes on your drain is from 6-3/8" to 6-3/5" apart, the D1 LARGE clip will fit.

You can use your pool basket as a measuring device. Put two strips of electricians tape on the “scoop” edge of your pool basket, separated by 6-3/8” inches as pictured below. From the side of the pool, place the basket “scoop” edge over your pool drain to measure the distance between the holes on the pool drain cover.
