This also comes with the XL self-empty base and self-cleaning brushroll. Which will definitely make your life a lot easier. That self-empty base can hold dirt and dust for up to 45 days. That number will vary depending on how you use your robot vacuum and how much dirt and dust is actually in your home. The Shark IQ AV1002AE also has a faster mapping feature now, so it is going to be better at mapping out your home and not missing a spot. It’ll clean row by row, so you won’t need to worry about it missing stuff. Or going in a random pattern and missing entire areas. Shark has also included powerful suction here, which uses deep cleaning to take on those larger debris and dirt that is tracked deep into the carpet. This is also really good for pet hair on carpets. Definitely useful for those that are allergic to pets too.
