incorrect brushes
Style: 24pcs * Accessories Kit
The side brushes do not fit my Dreame L40 Ultra. This kits brushes have a hexagon within a round shape to insert into vacuum as to where the actual shape that fits is a square. All the other items are fine though.

Great Value for Mova Owners 💡
Style: 24pcs * Accessories Kit
✅ Perfect Fit: Everything fits perfectly with my Mova P10. I’m probably set for the next year and a half by buying this in bulk. 🧹 Usage Tips: The dust bags last about a month, the mop pads can be washed and reused, the rubber rollers last roughly a year, and the filters about 3–4 months. 🤖 Smart Reminders: My Mova tells me when it’s time to switch things out, which makes upkeep super easy. 💰 Worth Every Penny: The quality is solid, the fit is perfect, and it’s absolutely worth the price.
