The IRIS USA Cordless Vacuum has a wide cleaning path to pick up crumbs, dust, pet hair, dander, and other debris. The 2-stage Centrifugal Separation System uses advanced cyclone suction to divide small and large particles, while maintaining suction power at 99%+. The power head brush roller (P model only) spins at up to 60,000 RPM for powerful cordless cleaning performance. The rechargeable battery runs ~35 min on Low or ~15 min on High on a full charge, with full suction power the whole time. The easy-to-read indicator on the control panel shows you how much battery is left, so you know how much clean time you have left. A full recharge of the battery takes ~4 hours.For most types of flooring (hardwood, tile, low rugs). The IRIS USA Cordless Vacuum lays down flat and can flex up to 90 degrees for impressive reach. Swivel steering allows you to clean under beds and furniture with ease. Remove the middle extender tube for more versatility or attach the included crevice tool to make it even easier to clean stairs, upholstery, cars, RVs, boats, and more. The double filtration system uses both a sponge filter and an exhaust filter to catch fine dust particles and help keep the exhausted air clean. When you’re done cleaning, you can empty the dust cup easily with the press of a button. This durable dust cup is 100% washable, and saves you money over expensive vacuum bags. The rechargeable battery and filters are easy to install and remove, so you can replace them whenever you see fit. For regular use, clean the filter every 2–4 weeks, or more frequently if vacuuming daily in homes with pets or heavy debris. If you notice reduced suction, it may also indicate the need for filter cleaning.
