Pool robot transforms into an underwater vacuum cleaner. Compatible with Talosbo S1Pro.

Background:

Unfortunately, our pool robot for the large pool broke down after a year and had to be sent in for repairs. Knowing that the repair could take 3–4 weeks, I bought a small, inexpensive Talosbo S1Pro to use in the interim. Due to the very slight slope of the floor and the 12-meter length, the cleaning performance was actually very poor, and dirt kept accumulating in the same spots. After all, it was only supposed to be reasonably okay as a stopgap solution. The S1Pro likely works quite well for smaller pools. So I decided to convert the pool robot into an underwater vacuum cleaner and clean the dirty spots by hand, which worked really well. That should certainly be achievable for a hobbyist beginner using Fusion 360 and 3D printing ;-). The result is impressive.

Realization:

First, of course, the left and right exhaust outlets—which provide the propulsion—had to be completely deactivated, requiring the flow to be redirected upwards. Then, just add a flexible joint connecting to the telescopic pole, and it's done! All parts are compatible with Talosbo S1Pro.

Part 1: This part attaches to the bottom of the carrying handle.

Part 2: This component, featuring the pivot pins, attaches to the top side of the carrying handle. After printing, the joint hole must be fully re-drilled to 8 mm. Parts 1 and 2 are fastened together using 4x20 mm countersunk screws. Supports only in the area of ​​the lower curve.

Part 3 is the joint fork for Part2. Again, re-drill the 8mm joint hole. The joint connecting Part 2 and Part 3 is assembled using an M8x80 screw and a self-locking nut. The mount for the telescopic poles accommodates a 22mm diameter. Since other poles might be used, this file is also available in F3D format, allowing anyone to make their own modifications. To secure the telescopic pole, I use an M6x60 screw with a wing nut on each side, making the pole easy to remove. Support only for inside the 22mm diameter hole.

Part 4 is the water outlet deflector. It is also attached to the Talosbo S1Pro using 4x20 mm countersunk screws, utilizing the small longitudinal slots on the S1Pro. The two turquoise-colored outlet flaps must be folded all the way back so that Part 4 can be installed. To make this part fit on the 250x250 build plate, you need to rotate it 45° and print it diagonally on the plate.

Designed in Fusion 360, printed on an Anycubic Kobra S1 using PETG silver, 0.2 mm layer height, 30% infill Gyroid, 10 walls. For print orientation, see photo. All the screws and nuts are, of course, made of stainless steel. You can actually get them at any hardware store.

One advantage is that the S1Pro is now finding a new use as a vacuum cleaner, instead of just gathering dust on a shelf in the basement. If anyone builds this, it would be great to see your makes here.

This part is a custom-designed accessory for the Talosbo S1Pro pool robot. Talosbo and S1Pro are used solely to clearly describe compatibility.
