I got tired of my Dirt Devil Spider 2 robot vacuum getting stuck under our furniture as it is just about the same size as the vacuum and it would force itself underneath it, get stuck and sound the alarm.

Instead of continuously freeing and restarting it, it got kind of discontinued and forgotten.

Now, after some time, I decided to give it another chance and designed these bumper extenders to snap onto the bumper of the vacuum.

After a week of testing, running it daily, I have to say it actually works perfectly and I enjoy using the vacuum.

I used 6 extenders (closed)

I added an open extender as a replacement part, in case one would break, that way you don't have to replace everything.

Might also fit on other Dirt Devil robot vacuums.

If it doesn't stick onto your bed as it is quite narrow, use some sticking additive like 3DLAC, glue stick or hairspray or print with a brim/raft.

Snap on all extenders onto the bumper.
Run a piece of filament through the holes and cut it to size. I opted for some PETG.

Fixate the filament to the outer extenders using super glue.

It doesn't really make any difference to fixate the inner extenders in my opinion.
