Good

Very high quality kit that comes with everything necessary to install them on to your robot the only drawback is that the screwdriver that comes with it is a little weak and may bend when unscrewing the brush

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.

Full Refund on Vacuum
I purchased the 3 year plan for my robotic vacuum. It stopped working at about the 1 year point. Went to their site, printed the prepaid label, dropped it off at UPS store near me. The sent an email letting me know they received the vacuum, then another email that they were trying to repair it, then another email about two weeks after I mailed it letting me know that a gift card for the full amount would be issued via email to mail as they could not repair it. Took the gift card credit on amazon and purchased a different vacuum. I bought the insurance again, it is worth it!
