i absolutely love this vacuum. i’ve been skeptical of cordless vacuums with  bad experiences w/shark and dyson. this  thing blows them away big time. its actually too powerful for me to use on high on my carpets + battery time is awesome. i have a 4 bed 2 bath home 2,000 sqft & a single charge  on med is enough for my entire home & still not die. cleaning  is a breeze and goodbye foam filters! 1 thing i need help with if possible is i want to buy an extended warranty but i don’t know how to do this. can someone help me and direct me where to go? thanks for the amazing device samsung!!
