Enhance Your Shark ION Robot Performance with SOFOXYI 6Pcs Side Brushes Replacement Kit – Compatible with AV751 R85 RV850 RV850BRN RV850WV S87 RV851WV RV700_N RV720_N RV750_N Review

I bought them in September and in January all six were broken. My previous brushes lasted over two years and never broke. I think you pay for what you get.

Looks ok but very difficult to confirm correct size. Our Ion came from Costco and was supposed to have its own model number. We have an almost identical non-Costco ion on a different floor. In any case, the round fastener is too big for proper installation, so they fall off easily.

We have been using our Shark every day for almost a year and up to its week have never had a brush break. I was so excited to find a 6 pack replacement on Amazon. The brushes look exactly the same but broke on first use. Very very badly done. Don't waste your time and money on this. . :(

I liked the price but they seem easy to break. I don't know why or if the originals don't break so easily. I replaced the original ones that didn't break just to see if they work. I only bought these to have extras on hand. They work well, but I'm too new to Shark and the originals to comment on the durability of these brushes.

I bought a set of 6 replacement brushes. I put the first 2 on my Shark Ion and they lasted 2 cleaning cycles. Then I replaced them with the second 2 and they only lasted 1 cleaning cycle. I then replaced them with the last 2 and they lasted 3 cleaning cycles. At this rate it will be cheaper to buy a new Hai-Ion. I wouldn't waste your money on these replacement brushes. Very cheaply built.
