I have 6 cats, 4 males & 2 females, and they share 2 Litter Robot 3 Connects. I bought the Robots refurbished just after my husband died as I am not physically capable of scooping litter boxes. Scooping was one of the few things he still did even with his dementia. If I didn’t have the robots I don’t know how I would have coped as my cats are my children. Everybody uses the robots and they don’t seem to have a preference as to which one, except the tray in the one in my office usually needs to be dumped sooner. I use the cheap 13 gallon twist tie garbage bags to line the trays and change the bags once a week for garbage day. It takes about 10-15 minutes to change the bag and add some litter to replace what has clumped up into the tray. I’ve never taken them apart and cleaned them because I use better litter. I don’t bother with the carbon filter and I don’t have an odor problem.
There didn’t seem to be much of a changeover hassle. I set them up, put a little used litter from one of their old boxes in the drums, and took away the old boxes. My youngest was fascinated with watching the drum go around, but the novelty quickly wore off. There is a way to put the cycling on hold at night so it doesn’t wake you up from a sound sleep, but I don’t bother with it. There is a blue light that comes on inside the drum at night so Kitty can see to do their thing.
I do buy better litter, currently using the Arm & Hammer Slide so the clumps don’t stick to the drum and fall into the tray easily. I tried the cheap Walmart litter and it didn’t clump enough so I was constantly scraping poop into the tray as it cycled. The cycle can be set for however many minutes you want it to wait after the cat exits. Mine came set at 8 minutes so it gives the litter time to clump well.
I have had only one problem with “malfunction” in that after about a year the sensors wore out on the base of one unit. I purchased the extended warranty when I bought the robots, so I called them and told them what was going on. They wanted me to try to replace the sensors, but once I said I physically couldn’t do it, they sent me a whole new base with the tray by UPS, no charge. I had it within a couple days and just scooped the litter in that robot until it got here. Roped a friend in helping me change the drum onto the new base. I can’t say enough good things about their customer service.
They’ve sold millions of these things. The people who have problems are the ones that post reviews and half the time if it cleaned itself and gave gold coin rewards they’d still find something to complain about. The rest of us just go on with our lives and don’t worry about reviews. I love my Litter Robots. They’re worth every penny. If one of them gives up the ghost after the warranty runs out I’ll gladly fork over another $600 or whatever they’re charging at that point to buy a replacement.
Be forewarned, the box it comes in is HUGE. You open it up, take out the contents, put the globe on the base, put the liner on the tray, the tray into the slot, add litter to the line in the globe, plug it in, and turn it on. It’s not rocket science. With 8 cats you may have to empty the trays sooner than once a week, but the bags are cheap. Dollar General has a roll of 10 for $1.00. You don’t need the waste bags they sell on their web site, any 13 gallon twist tie bag will work.
