Hi all, I have a house full of cats (I foster), and I need to replace my crappy handheld cordless vacuum cleaner. I was wondering if anyone can recommend one. Reviews often talk about how good handhelds are with picking up pet hair, but they never mention the main thing I use it for--stray litter. I've had some upright vacuums that spit litter right back out in the exhaust, and my previous handheld let the clumpable litter dribble out of the vacuum when it was turned off. I'm looking for a 20v, cordless handheld with decent run time after charging. Thanks in advance for your suggestions.
