The kit itself is decent. The silver faceplate is a nice-looking cosmetic upgrade. Also, be advised that if your Roomba is compatible with the lighthouse, you’ll still need a pair of ‘C’ batteries to power the lighthouse.

While some users won’t have a need to ever replace their brushes, my circumstances are different and I will probably need to replace them annually. This accessory kit is a good deal at the usual price, and was a great price at the Gold box special for $39.00. As an added bonus, the box came with 4 of the bristle brushes, 4 of the beaters, and extra filters rather than the three sets of brushes shown in the photo.

Golden retrievers + Roombas = a happy dog owner with a clean house.

- Sliver faceplate – not needed, unlikely to be ever needed. It’s not clear if it fits all 500 models.

- 3 side brushes – after one year of use, our side brush does look a little dirty. I may want to replace it sometime but, over the expected lifetime of a Roomba (3 years?) I would say that one extra, maybe 2 extra would be sufficient.

- 6 filters – the filters can be cleaned easily. I believe that we got 2 of them to begin with but I don’t see why I would want to replace the existing one. It still looks good after one year.

- 3 flapper brushes – the one that comes with the Roomba should never require replacement. Getting 3 of them almost guarantees that 3 flapper brushes are going to end up in the trash in a few years because they will never be used.

- 3 bristle brushes – we are still using the original one. They tend to get dirty as they catch hair but you either clean them and remove the hair all the time or you will have to keep replacing them after every couple of uses. For as long as you clean the brush, you will not need a replacement for the first couple of years of use or maybe forever.

- 1 virtual wall – whether this is needed, it’s anyone’s call. Since we have 2 Roombas, we got 4 of them and we are okay. 2 walls may not be sufficient. However, read the review preceding this one. The reviewer suggests that what you get in the bundle is a Lighthouse which, apparently is incompatible with the low-500′s models. I believe that the virtual walls are compatible with all the 500 series so, make sure that this is what you get if your Roomba is not a 535+.

Over the lifetime of a Roomba you may need one or 2 extra side brushes and, possibly, one extra filter or 2. Depending on your house layout, you may need more virtual walls or lighthouses. As far as I am concerned, this is it.

I am taking away 2 stars because, in my view, while each of the bundled components are good quality accessories, I see no need for most of them because they are not likely to be ever used as replacements over a Roomba’s lifecycle.
