PowerDetect Self-Empty
A vacuum-only Shark, first sold as the Detect Pro, that empties itself into a bagless base and boosts power on dirtier patches. Testers found it picks up well, but its app is basic and navigation divides opinion.

The short version
This is the vacuum-only member of Shark's PowerDetect family, sold in the US and first reviewed in 2023 under the name Detect Pro Self-Empty. It maps your home with a laser, spots dirtier areas and makes extra passes there, and lifts itself over door bars and onto thick rugs. After each run it empties into a bagless base that Shark says holds up to 60 days of dirt.
The trade-off is polish. There's no mop, and both testers found the app thin: one couldn't save maps for more than one floor, the other couldn't schedule individual rooms. Emptying is loud, and one tester saw debris drop out of the robot on its way back to the base.
Don't confuse it with the PowerDetect NeverTouch Pro 2-in-1, which adds a mop and a dock that refills water and cleans the pad. Shark's own listing for this model was out of stock when we checked.
Our take: Consider it if you want a straightforward self-emptying vacuum for one floor, you don't need a mop, and you don't want to buy bags. Skip it if you have a multi-storey home, since one tester couldn't save more than one map, or if you want room-by-room scheduling. If you'd like mopping too, the PowerDetect NeverTouch Pro handles the pad for you. The AI Ultra Self-Empty is a similar older, vacuum-only Shark.

What reviewers found
Two home tests, both of the model when it was called the Detect Pro Self-Empty. Top Ten Reviews used it for over three weeks in a multi-level home with several floor types, and Reader's Digest ran it for about ten days. Both liked the cleaning and both disliked the loud emptying and the limited app. They disagree about navigation: Reader's Digest saw no crashes at all, while Top Ten Reviews found it unpredictable around obstacles and watched debris fall out on the way back to the base.
Top Ten Reviews, hands-on, Over three weeks, Oct 2023 (tested on the Detect Pro Self-Empty (RV2820AE)) · Reader's Digest, hands-on, About 10 days (tested on the Detect Pro Self-Empty)
Navigation: flawless or erratic
Reader's Digest reported zero crashes or bumps thanks to its mapping, and found it thorough under beds and in awkward spots. Top Ten Reviews saw something different: it left at least six inches around a dog toy but ran over the tester's feet several times. It did recognise stairs, and it usually freed itself when stuck on a toy or rug. Clutter and pets moving around may explain the gap, so clear the floor for the first few runs and watch how it behaves.
Good pickup, weaker on fine dust
Top Ten Reviews found it cleared sprinkles on laminate even at low power, but left some flour and oats behind at every setting. It did better on rugs, and its dirt sensor appeared to boost suction over concentrated mess. It picked up dog fur well from hard floors but left finer hair in rugs, and it doesn't boost power automatically on carpet. Reader's Digest called it incredibly thorough and useful a few times a week, though not a replacement for a full-size vacuum.
Loud base, occasional spills
Both testers found emptying noisy. Reader's Digest compared it to a plane taking off a few blocks away, and Top Ten Reviews measured 75dB. Top Ten Reviews also saw oats and sprinkles fall out of the robot as it crossed thresholds on the way back, and more drop from the brush area when it docked, so some mess needed sweeping up by hand. The base is bagless, so there are no bags to buy.
A thin app
Top Ten Reviews found the app confusing and short on features. It couldn't save more than one map, so the tester had to delete the downstairs map to clean upstairs, and the map itself didn't separate rooms clearly. Reader's Digest could send it to specific rooms but couldn't schedule a clean of just a few rooms, only the whole house. If you want detailed room control, other brands' apps do more.
Long runs, slow charging
Top Ten Reviews got about two hours on normal power, enough for the whole lower level of the house, and it took about four hours to recharge. Reader's Digest listed slow charging as a drawback, at up to six hours. It took about an hour to clean that tester's single-level home. For a typical single floor, one charge should do.
Both reviews tested this robot under its earlier name, Shark Detect Pro Self-Empty (RV2820AE). Shark now lists it as the PowerDetect Self-Empty; the retail version is AV2820AE.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
Don't rely on it. Top Ten Reviews found its obstacle handling unpredictable, giving a toy a wide berth but running over feet. Reader's Digest had no crashes at all. Neither tested pet waste, so keep accidents and loose cables out of its way.
Does it work on more than one floor?
Not easily. Top Ten Reviews couldn't save more than one map, so it had to delete the downstairs map to map the upstairs. If you have two or more storeys and want the robot on each, pick a model that stores several maps.
How often do I have to empty or refill anything?
Rarely. Shark says the bagless base holds up to 60 days of dirt, per the specifications, and Reader's Digest notes real-world use will vary. There's no mop or water tank. Top Ten Reviews did have to clean up debris that fell out of the robot near the base.
How does it handle rugs and door bars?
Shark says it lifts itself over thresholds and onto thick carpets, per the specifications. Top Ten Reviews found it usually freed itself when caught on a rug or toy, but some debris fell out as it crossed thresholds. Nobody has measured how high a step it can climb.
Does it fit under low furniture?
Gaps of about 9cm or more. Top Ten Reviews measured the robot at 13 x 13 x 3.3 inches, and Reader's Digest found it cleaned under beds more thoroughly than the tester managed by hand.
Compare with
AI Ultra Self-Empty
An older vacuum-only Shark with laser mapping and a bagless base that picks up well on hard floors.
It bumps into small objects and struggles with hair pressed into carpet.
PowerDetect NeverTouch Pro 2-in-1
Adds mopping, and its bagless dock empties the robot, refills it and cleans the pad for weeks.
It leaves floors wet and the app gives you little control.
Q8 Max+
A self-emptying vacuum that reviewers rate for pickup and mapping, with a basic mop added.
Edges and small obstacles still catch it out, and long hair tangles on its rollers.
