If your Shark robot vacuum isn't picking up like it used to, these replacement side brushes will probably fix it! This 10-pack gives you plenty of spares for when those little brushes get worn down from regular use. They're made from durable plastic that holds up well and installs in seconds - just pop off the old one and snap the new one into place. Super compatible with Shark IQ R100, R101AE, RV1000, RV1001AE, UR1005AE and a bunch of other models (seriously, they work with like 20 different Shark vacuums). The black color matches the original perfectly, and the quality is actually really good - no flimsy plastic or weak bristles. Most people don't realize you should replace these brushes every 2-4 months to keep your robot vacuum cleaning at peak performance. Having 10 means you're set for years of maintenance without having to reorder. They come in simple packaging but work exactly like the expensive OEM parts. Whether your current brushes are looking sad or you just want to be prepared, this 10-pack is seriously smart to have on hand. Your robot vacuum will thank you with better cleaning performance!
