Replacement for iRobot Roomba s9+ s9 s9 Plus Filters, 12 Packs Replacement Parts Compatible with Roomba S9+ (9550),S9（9150),Roomba S Series Replacement Parts

Filters fit perfectly and are a great substitute for the more expensive iRobot branded filters. Easy to install.

These work perfectly - I do cringe when I realize the country that is profiting from making them.

Absolutely perfect for my Roomba S9+. I have 4 dogs so my Roomba gets used a lot. These filters fit exactly and filter the same as stock. Not an upgrade or downgrade. A huge savings.

THE filters look just like the IROBOT filters and fit into the machine. I did find that the gasket on the filter is thicker than the filters from IROBOT, and to make them work for the first 2 or 3 times I used them, I had to tape the filter door shut with duct tape. After that they fit fine and have worked really well. I will buy them again when I need more filters in about a year.

So far same as original product.

Fits and works like OEM at an economical price

For Roomba S9 - Filters are slightly larger than OEM filters and the lid doesn't stay shut. I taped the lid shut in the hopes of it working and it works for a partial job and then errors out with "error 8" vacuum error. Basically doesn't keep the necessary seal. Don't order this junk.

These filters work perfectly! The price is right and they wash out and dry easily.
