"The maintenance I put in takes literally 3 minutes."
"it’s way less of a headache. ... If I’m still gonna have to clean on my own, at least I’m not dealing with untangling freaking dog hair and three women’s worth of hair every few days."
"Maintenance consists of a replacement canister once a year, like $100. However, it's pretty much maintenance-free otherwise."

"We have three kids, two dogs, and a cat that sheds more than both dogs combined, and having robot vacuums has been a game changer. ... But the robot keeps the main areas of the house from getting hairballs and dirty."
"I've had my roomba for like 5 years now.. We have 3 big dogs and a cat, in a small house. Still works great, I've replaced the brushes and obviously the filters on it but it still works awesome."

"I run it every day. ... It saves me at least an hour worth of sweeping a week."
"Honestly it is brilliant ... Instead of getting the big vacuum out almost daily, it comes out about once a month now."
"We have two small dogs and five children. The floors are one thing I don’t have to worry about anymore. ... they run every day, this keeps the stairs pretty clean and I vacuum the stairs once a week."

"The fan that circulates the air is so ridiculous it sounds like an airplane is idling inside my house, and it literally changes the air pressure in my kitchen and hurts my ears"
"The biggest issue is the noise it makes, I move a lot from side to back and vice versa during the night. The noise sounds like balloons rubbing against each other. I've tried wrapping it in a blanket, which helps a bit but still makes a lot of noice."
"Loud as hell. ... Ditto works really well, but loud as hell."

"they are not sturdy. ... Actually, I think I’m on my 5th pair in 2 years and I am a weekend overnight backpacker. ... I’ve had the treads come loose less than 15 miles out of the box. ... Their durability is crap to the point it’s hard to believe a legit company accepts this as their product."
"They’re dogshit for rocky terrain with mesquite and cacti around. ... The bottom of the sole is 95% foam and cactus thorns and mesquite spines will go right through them into your feet, ask me how I know lol. ... An absolute no-go for rugged hikes in the desert."
"they begin to fall apart after 200 miles. ... these shoes often don't last a year at the rate I use them. ... I put in a warranty claim regularly because these shoes often don't last a year at the rate I use them."

"the mopping function is useless"
"However, the few times I have attempted to use the mopping feature, it has not worked well at all. ... It starts off fine, but after no more than 10 min if that, it seems to get stuck. ... What it's stuck on is beyond me because it happens in dining room each time & sounds like it's spinning it's wheels (like a car stuck in mud). ... There are no rugs, chairs are moved out of the way & there's no visible debris obstacles like one of my son's marbles or a plastic milk cap or anything. Literally just hardwood flooring. ... I've tried rebooting, I've tried popping the water/mop pad on & mopping immediately (thinking it would help reduce soaking & "puddling" near the wheels), I've tried wiping the wheels and following behind it to wipe up the drag marks of water. But it still spins & does nothing."
"I had to replace it once because one of the mop spinning motors stopped working"

"the second one required a call to Amazon's tech help within the month. ... They told me how to do a factory reset. That worked for about a month. ... Then it started beeping continuously and wouldn't run."
"My guess is it might be something to do with my wireless so I'm not sure I can blame the robot. ... Maybe if they went back to the drawing board and just made a robot you didn't have to use your phone to work. ... That would take one unknown out of the problem of fixing them when they go wrong."
Lefant has been decent. Has never got lost. Seems to not miss anything.
r/RobotVacuums • I fucking hate this thing ->I love mine, use it at least once a day due to the amount of shedding my dogs do. not a deep cleaner but works great keeping things under control. bought one for my son and he loves it too.
r/RobotVacuums • Need advice: how's Lefant's robot vacuum? ->Reading this I wonder if robot vacuums are ready for prime time -- all of them. I have two Lefants. One worked great for years, the second one required a call to Amazon's tech help within the month. They told me how to do a factory reset. That worked for about a month. Then it started beeping continuously and wouldn't run. What it had must be contagious (snark) because the one that worked great started doing something similar -- runs about one minute then stops and starts beeping. Tech help was no help. My guess is it might be something to do with my wireless so I'm not sure I can blame the robot. Maybe if they went back to the drawing board and just made a robot you didn't have to use your phone to work. That would take one unknown out of the problem of fixing them when they go wrong. Just an observation after reading the posts here.
r/RobotVacuums • Dreame is a scam ->lol what the fuck got up OPs ass about robot vacs? I have a LeFant I got for $90. Thing runs 4 hours or so on one charge. I run it every day. I only empty it once a week. The maintenance I put in takes literally 3 minutes. It saves me at least an hour worth of sweeping a week.
r/unpopularopinion • Robot vacuums are expensive and a waste of time. ->I have a cheapo LeFant that I got for free. Just swapped the battery. It's only a vacuum. I swear by it. We only have 1 kid but the crap that, that thing sucks up is incredible. Sometimes it even gets little toys. It's a heck of a machine. I'd recommend it.
r/homeowners • Are robot vacuums worth it? I’ve got 4 small kids and I’m always sweeping up the kitchen. Now I have a crawling baby so I’m thinking about getting a robot vacuum, preferably the mop/vacuum kind but they are so expensive! Curious if they are worth it and an investment. ->I'm sitting here regretting my Lefant purchase from 18 months ago. I'm sure you weren't thinking of going that cheap, but in case you're tempted. I'm shopping again.
r/RobotVacuums • Help me choose a robot vacuum? ->I bought Lefant on Amazon 1 year ago and I love it. We had some issue with water tank and they sent new one for free
r/RobotVacuums • Need advice: how's Lefant's robot vacuum? ->I have a cheap Lefant robot vac that I run every night that is well worth it, only paid $100 and it keeps my floors very clean with 2 dogs. Like it better than the shark I paid 5x as much for.
r/dogs • Is a Roomba-like vacuum worth it for dogs? I need to be de-influenced for my wallets sake ->A robot vaccum is worth it, IMO, but there are cheaper models than a Roomba. We had an Ecovacs Deebot for several years and now we have a Lefant model. We bought both heavily discounted on Amazon Prime day.
r/dogs • Is a Roomba-like vacuum worth it for dogs? I need to be de-influenced for my wallets sake ->I have the same number of animals. I broke down and bought a cheaper sort of robotic vacuum, without all the bells and whistles. I run it every other day—sometimes daily. I think I paid $95 for it on Amazon. I live in under 1000 square feet. It is a Lefant. One day I will upgrade to one with greater capabilities, but for now it is heaven.
r/CleaningTips • I'm about to check myself in a mental institution ->I have one and it works well
r/RobotVacuums • Need advice: how's Lefant's robot vacuum? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
