- 1 HEPA Self-Empty Base
- 2 Side Brushes
(components list taken from the manufacturer listing; if you see different items in the retailer package, follow the retailer’s contents.)
Design & Build
The Shark AI Ultra robot uses a low-profile disc shape common to top robot vacuums, which helps it slide under couches and tables. The outer shell appears to be a durable, matte plastic that resists scuffs; precise materials aren’t specified by the listing.
At typical robot-vacuum size, it’s compact enough for most furniture clearance but tall enough to accommodate lidar and a tall dust chamber in the chassis. The self-emptying base is considerably larger than a standard charging dock because it contains a bagless dirt reservoir capable of holding multiple cleaning sessions’ worth of debris.
Ergonomically, controls are minimal on the unit itself — the product is intended to be managed via the app, voice assistant, or scheduled cleanings. The included side brushes and self-cleaning brushroll reduce the need to frequently touch the main brush, which helps keep maintenance simple.
Key Features
Powerful suction for all floor types
Benefit: The unit emphasizes “incredible suction” to pick up dirt and debris across carpets, rugs, and hard floors. That translates into fewer missed particles when moving between different floor surfaces during a single run.Where it helps: High-traffic entryways, kitchens with crumb-prone areas, and pet zones where fur and tracked-in dirt accumulate.
Matrix Clean Navigation
Benefit: Matrix Clean Navigation lets the robot clean in a precise grid and make multiple passes over areas of dirt, rather than roaming randomly. This systematic approach improves coverage and reduces the chance of missed spots.Where it helps: Open-plan living rooms, multi-room routines where you want even results, and when you want predictable cleaning paths for scheduling.
Self-emptying base with HEPA filtration
Benefit: The bagless self-emptying base stores debris for extended periods and captures 99.97% of particles down to 0.3 microns with true HEPA filtration.Where it helps: Homes where occupants suffer from allergies or where you prefer minimum contact with dust — the base can hold many cycles so you don’t need to empty it as often (source: listing, checked 2025).
360° LiDAR-guided mapping
Benefit: The robot uses 360° LiDAR vision to quickly and accurately build a map of your home, enabling methodical cleaning and better obstacle detection in light or dark conditions.Where it helps: Complex floorplans, multiroom cleaning, and homes with shifting furniture where the robot needs to adapt each run to avoid furniture and toys.
Self-cleaning brushroll
Benefit: A self-cleaning brushroll reduces hair wrap and the need to manually cut hair from the roller, which keeps suction and pickup consistent between maintenance sessions.Where it helps: Homes with shedding pets or long-haired household members where hair on brushes is a constant nuisance.
Pet-friendly pickup and filtration
Benefit: The combination of strong suction, a self-cleaning brushroll, and HEPA filtration is aimed at capturing pet hair, dander, and allergens effectively.Where it helps: Multi-pet households, beds and sofas that accumulate fur, and rooms with carpets that trap dander.
Hands-free control and smart assistant integration
Benefit: Set schedules, start on-demand cleans, and control the robot by voice with Amazon Alexa or Google Assistant.Where it helps: If you want to start a clean while leaving the house, or integrate the robot into a smart home routine (for example, run when you say “Goodnight” or at a set time each day).
Extended runtime and Recharge & Resume
Benefit: Up to 120 minutes of runtime per charge lets the robot attempt whole-home cleaning on a single run in many homes. If the battery runs low mid-job, the robot returns to dock, recharges, and resumes where it left off.Where it helps: Larger houses or multi-room jobs that exceed a single-charge duration (source: listing, checked 2025).
Where to buy
Performance & Use
Setup is typical for modern robot vacuums: place the dock against a wall with a little clearance, power up the base, and follow the app prompts to connect the robot to your Wi‑Fi and create a home map. Because the unit uses LiDAR mapping, the first run will build a detailed floorplan that you can edit in the app to set no-go zones, assign rooms, and prioritize areas.
Practical tips
- Let the robot perform an initial mapping pass at night or when fewer obstacles are present. A clean map improves future routing.
- Remove low-profile objects, cables, and loose rugs that might trip the robot during its first mapping and cleaning sessions.
- Although the base holds up to 30 days of debris (source: listing, checked 2025), check it after high-debris events (moving, parties, remodeling) and empty sooner if you notice reduced suction or increased odor.
- Clean the side brushes and check the brushroll occasionally. The self-cleaning brushroll reduces hair buildup, but small tangles can still accumulate over many cycles.
- Replace HEPA filters as directed by Shark’s maintenance guidelines (interval not specified in the listing); inspect filters if suction seems weaker or if you notice dust escaping the base.
- Use scheduled routines for predictable upkeep. For households with pets, daily morning or evening runs keep fur and dander from settling into carpets.
Maintenance
- Empty the base only when the app or indicator suggests it is full, or if you notice a performance decline. The bagless design means you won’t need replacement bags but you will need to clean the base occasionally.
- Keep the LiDAR sensor area clear of dust on the robot’s top to preserve mapping accuracy.
- If the robot frequently stalls in one spot, check the floor for debris or something the lidar couldn’t detect (transparent or very low items can still confuse sensors).
Real-world performance expectations
- For homes with moderate foot traffic and regular maintenance, the Shark AI Ultra robot’s suction and navigation should handle daily messes with minimal oversight.
- In homes with heavy shedding or abrasive debris (e.g., sand), expect to occasionally clear higher-than-average debris from the side brushes and base.
- The Recharge & Resume function reduces the need to micro-manage mid-cleaning interruptions, improving total coverage across large areas (source: listing, checked 2025).
Pros vs Cons
| Pros | Cons |
|---|---|
| Strong, multi-surface suction for effective pickup (source: listing). | Manufacturer suction numbers and exact airflow/suction metrics not provided in listing. |
| Bagless self-empty base holds up to 30 days of debris; true HEPA filtration captures 99.97% of 0.3 micron particles (source: listing, checked 2025). | Base is large and needs its own floor space; bagless design means occasional base cleaning required. |

Who Should Buy
- Households with pets who need routine hair and dander pickup without daily manual vacuuming.
- People who prefer set-and-forget cleaning: those who want a robot that empties itself and runs on a schedule.
- Owners of mixed-floor homes (wood/tile and carpet) who want consistent performance across surface types.
- Buyers who value mapped, systematic cleaning over random navigation.
Who Shouldn’t Buy
- Customers who require the most compact docking solution or have very limited wall space for a larger self-empty base.
- Those who want the lowest up-front cost and don’t need advanced features like LiDAR mapping, HEPA filtration, or a self-emptying dock.
- Buyers who need detailed manufacturer performance specs (exact suction power in Pa, noise levels, or battery chemistry and cycles) — those figures aren’t listed in the retailer’s description.
- People who prefer a fully bagged disposal system; this model’s base is bagless.

I bought this vacuum on Prime Day to replace another brand that couldn’t handle my German Shepherd’s hair — I was constantly stopping it to pull out tangled fur. After reading reviews and comparing models, I went with this one and so far I love it.
My whole house is hard floors (wood and tile) and it cleans both very well. The roller isn’t a brush-style roller, so hair doesn’t get wrapped around it. During setup it mapped my home accurately, and I was able to create zones/rooms to target high-traffic areas. Through the app I can choose cleaning modes (eco/normal/max/ultra); I keep it on Ultra Clean. Instead of running randomly, it vacuums in neat rows and does the edges, which makes a big difference.
The robot returns to its base and the base automatically sucks the hair and dirt into its storage bin — I named mine “Hair Destroyer.” It recharges reliably, and scheduling is easy (I run it Mon/Wed/Fri/Sat). It also does a good job on small rugs by the doors.
The clearance is a bit tall (about 4½ inches), but it still fits under my couches and most furniture. Narrow corners around plants require my dust mop, so it’s not perfect, but it’s very close. With the amount of hair it picks up I empty the base every other day; it filled quickly the first few runs because there was so much hair.
It’s quieter than my previous machine. It plays a sound when it goes to empty and a different sound when it returns — not bothersome to me. Be sure to let it fully map your house and register the product. I did have one charging issue that I think was user error; customer service was helpful and walked me through basic troubleshooting that resolved it.
Overall I’m very pleased and wanted to share because this unit actually works for pet hair. I’ll update if any problems arise.

With two big dogs and a cat, keeping the house free of pet hair is a constant battle, and this robot vacuum has made it so much easier. It effectively lifts hair and debris from both carpet and rugs without tangling or flipping up the edges. The dock tucks neatly into a corner (mine fits perfectly under a table), it’s MUCH quieter than the two previous “top of the line” robots I tried, and it moves more gently and intelligently—no more running over my toes.
Setup and mapping were quick and easy, and the overall feature set is impressive. I do wish it had two small additions: the ability to include or exclude specific rooms when scheduling cleanings, and an app alert for when the dust bin is full. Even with those minor drawbacks, Shark vacuums are reliable, efficient, and a lifesaver for pet owners. I’d choose this over any other robot vacuum—well worth the money.

It took me over four hours to connect it to Wi‑Fi — really difficult, and many others seem to have the same problem. The app isn’t available in all regions, so you need an account in a store region that offers it. If you bought the robot internationally on Amazon, you must select the region where you purchased it in the app, not the region where you’ll use it.

I was initially skeptical after reading another review that changed their mind, but this robot surprised me — it works very well.
The app pairs easily with my Android after following the download and installation instructions and enabling Location (which I almost never do). Once paired the phone and robot communicated smoothly. That said, neither Wi‑Fi nor the app are required for basic cleaning — they’re mainly for programming zones and schedules.
Before pairing, after a full charge I just turned it on to see what it would do. It spun to orient itself, found and “kissed” the dock, then went to work on my wood floors. It navigated around the dining table and chairs, didn’t get stuck under the rockers, cleaned the living room area rug fine, went into every room and even cleaned the back hall by the back door. It found a little pile of coarse sand in my husband’s room and picked it up (I wouldn’t recommend feeding it sand on purpose). I was impressed by how much hair and lint it collected.
There are limitations: it’s too tall to reach toe‑kicks, the round shape struggles with tight corners and some edges where floor meets wall, and certain spots will still need a broom or hand brush. It also can’t deep‑clean very dirty plush carpet the way a heavy upright with a strong beater bar can — but that’s not its claim. After I pre‑cleaned the carpets with my upright and then ran the robot every couple of days, it began lifting the pile in high‑traffic areas. My carpet hasn’t looked this good in years.
The app has useful options to return to the dock to recharge and resume, and to empty itself and continue — very handy features. I highly recommend this machine for anyone, not just the elderly. The entertainment value alone made it worth the price, and it saves a lot of time.
This robot is simply brilliant.
