perfect fit for the L40 Ultra
Color: L40 Ultra Accessories
I'm very pleased with this accessories kit. All the included items work perfectly with the L40, and are good quality, fit correctly, and cause zero issues. They install just as the OEM items do, and the L40 works exactly the way it did when it came out of the box. I was particularly pleased that even though it's a replacement, it came with another little screwdriver, as I'd misplaced the original.
These hepa filters fit snugly, stay in place, and work to take up dust and trap it rather than just spread it around the house. The mop pads appear to be good quality and get the job done. I like how they attach - easy to put on and take off, just like the OEM, so I can clean them easily and use them for a little longer. The main brush is so close to identical that I can't really tell them apart, and they work as advertised - little wrapping and tangling, and they deal with dog and cat hair without a hitch.
In all, this is a good value for replacement components that work and are good quality. Recommended.
