I’ve spent the last month running nine different robot vacuums across my clients’ homes and my own 1,000-square-foot two-story, specifically hunting for the one that can handle the thick, plush carpet that most bots treat like a wall. The winner surprised me, and it wasn’t the most expensive unit in the lineup.
The Roborock Q7 L5 is the best robot vacuum for thick carpet I’ve tested, because it climbs a 0.75-inch plush pile transition without stalling, and it doesn’t leave a line of fur at the edge of the rug like every other bot under ~$159.99.

Every bot ran for a full month in real homes. I tested on my low-pile living room carpet, a client’s plush bedroom carpet, a matte-finish tile kitchen, and a hardwood hallway with a 0.5-inch threshold into a sunken living room. Dusty, my 62-pound lab mix, provided the fur. The cats provided the litter trail.
The thick carpet problem
Most robot vacuums are designed for hard floors and low-pile carpet. Thick, plush carpet, the kind that swallows your bare feet, is a different animal. The bot needs enough suction to pull debris out of deep fibers, a brush roll that doesn’t stall, and a chassis that can climb the transition strip without wedging itself like a car on a curb.
The Roborock Q7 L5 is the only bot I tested that cleared a 0.75-inch plush pile transition on the first try, every time, for four weeks straight. I didn’t rescue it once.
Pros:
- 8,000Pa suction pulled Dusty’s fur out of thick plush pile that my upright vacuum struggles with
- Climbed every transition I threw at it, including a 0.75-inch plush pile strip into a sunken living room
- Mapping was accurate on the first Explore run, no re-mapping needed
- 180-minute battery cleaned my entire first floor on a single charge
- Quiet enough to hold a conversation next to it
Cons:
- No self-empty base, so I’m emptying the dust bin every 2-3 runs
- The app is basic, no live location tracking
- Mopping is a damp cloth dragging behind, useless on carpet, light maintenance on hard floors
- At ~$449, it’s not cheap, though it undercuts the Roomba 415X by ~$150
Compared to the Shark AV2501AE AI Robot Vacuum
The Shark is my usual budget recommendation for clients who want self-emptying without spending ~$800. At ~$298, it’s a legit bargain. But on thick carpet, it struggles. The Matrix Clean pattern works, but it only runs on one room at a time, so I couldn’t set it to clean my entire first floor in that pattern.
The mapping is the bigger issue. My first Explore run missed entire 10-foot wall sections. I re-ran it twice before the map was accurate.
The Roborock mapped my floor correctly on the first pass. That’s the difference between a bot you trust and a bot you babysit.
The Shark’s self-empty base is a real convenience, but the foam roll filter inside the dock gets VERY dirty real fast. I was cleaning it every 2-3 runs. And the evacuation system is as loud as a typical upright vacuum. The Roborock doesn’t have that problem, but it also doesn’t empty itself.
Compared to the eufy E28
The eufy’s 20,000Pa suction is the strongest on this list, and it shows on hard floors. It picked up cat litter, crumbs, and Dusty’s fur on tile and hardwood without a second pass. But on my client’s plush carpet, it stalled on the transition strip.
I watched it spin its wheels for a full minute before I rescued it. It also got stuck on a rug with tassels, which is a dealbreaker for anyone with decorative rugs.
The Roborock’s 8,000Pa suction is lower on paper, but it outperformed the eufy on thick carpet because it didn’t stall. Suction specs are marketing. Bin fill is truth. The Roborock’s bin filled with real fur and dust after every run. The eufy’s bin filled with air and frustration.
Design
The Roborock Q7 L5 is a matte black disc with a single brush roll and a side brush. It’s not sleek or premium, it’s just functional. The dust bin pops out from the top, and it’s easy to empty over the trash without making a mess.
The 3.5-inch height means it slides under my client’s sofa with clearance to spare, which is more than I can say for the Shark, which wedged itself under the same sofa so tight I had to tip the furniture to free it.
The eufy E28 is similar in design, but the app is where it falls apart. I had it crash mid-cycle twice in the first week, and the schedule reset itself after a firmware update. The Roborock app is basic but stable. No crashes, no lost maps, no "Something went wrong" with zero explanation.
Performance on thick carpet
This is the metric that matters. My client’s plush carpet is a 0.75-inch pile with a thick pad underneath. It’s the kind of carpet that swallows a standard vacuum’s brush roll and makes it stall. The Roborock Q7 L5 climbed the transition strip from the hallway onto the carpet without slowing down. It cleaned the entire room in a grid pattern, no bounce-around navigation, no skipping sections.
Dusty’s fur was the real test. He sheds enough to stuff a pillow every two weeks. The Roborock pulled fur out of the plush pile that my upright vacuum had left behind. The dust bin was packed after the first run. That’s the most honest metric I have.
The Shark AV2501S struggled on the same carpet. It got over the transition, but it left a visible line of fur along the edge of the rug where the brush roll couldn’t dig deep enough. The eufy E28 stalled on the transition entirely. The Tikom G8000 Max got stuck under the sofa, then immediately went right back into the same spot after I rescued it.
Battery and navigation
The Roborock Q7 L5 ran for 180 minutes on a single charge, which covered my entire first floor, about 1,000 square feet, with a mix of hard floors and low-pile carpet. The 150-minute battery on the Tikom G8000 Max was also legit, but the Tikom’s navigation was so inefficient that it bounced around the same 3-foot section for 20 minutes before moving on.
The Roborock’s mapping was accurate on the first Explore run. It labeled rooms correctly, and the no-go zones I set in the app worked exactly as intended. That’s rare. Most bots, like the Shark, need 2-3 Explore runs before the map is usable. The Roborock got it right the first time.
Durability and maintenance
I ran every bot for a full month, which is the only way to test durability. The Roborock Q7 L5 survived without a single stuck incident or app failure. The dust bin is easy to remove and empty, and the filter is washable. I cleaned the filter twice in a month, which is reasonable.
The Shark AV2501S’s foam roll filter in the self-empty dock needed cleaning every 2-3 runs. That’s a maintenance chore I didn’t expect, and it’s the reason I stopped recommending the Shark to clients who don’t like fiddling with filters.
The eufy E28 had a firmware update that reset my schedule and lost the map. I had to re-explore the entire floor, which took 10-12 minutes, and then re-set my schedule. That’s the kind of annoyance that makes a client call me at 2 PM on a Tuesday.
Value
At ~$449, the Roborock Q7 L5 is not the cheapest bot on this list. But it’s ~$150 less than the iRobot Roomba 415X, and it outperformed the Roomba on every metric I tested. At ~$449, if it lasts three years, that’s about 41 cents a day to not vacuum my carpet. That’s how I justify it.
The Shark AV2501S at ~$298 is the better value for someone who doesn’t have thick carpet. The self-empty base is a real convenience, and the no-go zones work properly. But if you have plush carpet, the Roborock is worth the extra ~$150.
The Tikom G8000 Max at ~$159 is a steal for an open floor plan with hard floors. But it gets stuck on quite literally everything, and the mopping is light maintenance only. If you have low furniture or thick carpet, you’ll spend more time rescuing it than you save.
Should you buy it?
If you have thick, plush carpet and you’re tired of rescuing a bot from under your sofa, buy the Roborock Q7 L5. It’s the only bot I tested that handles thick carpet without stalling, and it does it without a ~$600 price tag. If you have mostly hard floors and low-pile carpet, the Shark AV2501S at ~$298 is the better value, as long as you’re okay cleaning that foam filter every 2-3 runs.
What I’m testing next
I’m currently running the ILIFE A30 Pro through its second week to see if the 10,000Pa suction holds up on my client’s plush carpet. Early results are mixed. The transition is a coin flip, and the mapping is unreliable. I’ll update this review if anything changes.
Last tested: March 2025. Prices checked on Amazon at the time of writing.
