The Shark AV2501S and Lefant M330 Pro are two of the most popular robot vacuums under $300 — but they take completely different approaches. The Shark ($270) bets on power and convenience with AI navigation and a self-emptying base. The Lefant ($110) undercuts it by $160 and adds mopping. We've compared specs, verified buyer reviews, and real-world performance data to help you decide which one deserves your floor space.
Short answer: The Shark is the better vacuum if you want to forget it exists — the 30-day self-emptying base means truly hands-off cleaning. The Lefant is the smarter buy if you want a vacuum and mop in one and don't mind emptying it yourself. See all our picks in the full best robot vacuums under $300 guide.

The Shark's biggest advantage is the self-emptying base — it holds 30 days of debris with true HEPA filtration, so you only touch the dustbin once a month. The 360° LiDAR with AI obstacle avoidance creates precise home maps and cleans in a methodical grid pattern. It handles transitions between carpet and hard floor seamlessly, boosting suction automatically on carpets.
The trade-off: no mopping, and at $270 you're paying premium pricing. If you only have hard floors and want mopping, the Shark isn't the right choice regardless of budget.

- No common complaints in top verified reviews
The Lefant delivers a vacuum-and-mop combo for $110 — less than half the Shark's price. Its dToF LiDAR navigation scans up to 15 meters for smart route planning, and the carpet detection automatically avoids rugs when mopping. The 200ml water tank and washable mop pad handle light maintenance cleaning on hard floors.
The trade-off: no self-emptying base (you'll empty it after each run), less powerful suction than the Shark, and fewer verified reviews to judge long-term reliability. At this price, that's a reasonable compromise for most homes.

- You value reliability — 8,000+ reviews back it up
Get the Lefant M330 Pro if...
- You want vacuum + mop in one device
- You have mostly hard floors
- Budget matters — it's $160 cheaper
- You don't mind emptying the dustbin after each run
Frequently Asked Questions
Is the Shark AV2501S worth the extra $160 over the Lefant M330 Pro?
If you want a truly hands-off experience, yes. The self-emptying base means you only deal with the dustbin once a month. The Lefant requires manual emptying after each run but adds mopping, which the Shark lacks. The price gap comes down to whether you value convenience (Shark) or versatility (Lefant).
Which robot vacuum is better for pet hair?
The Shark AV2501S is the stronger choice for pet hair. Its more powerful suction and self-emptying base handle the volume of pet hair better — you won't need to empty it daily. The Lefant handles pet hair adequately on hard floors but may struggle on thick carpet.
Can the Lefant M330 Pro replace mopping by hand?
For light maintenance mopping, yes. The 200ml water tank and washable mop pad handle dust and light spills on hard floors. For sticky messes or deep cleaning, you'll still need a traditional mop. Think of it as keeping floors presentable between real moppings.
Do both robot vacuums work with Alexa and Google Home?
Both support app control and scheduling. The Shark integrates with Alexa and Google Assistant out of the box. The Lefant also supports voice assistants through its companion app. Both let you set no-go zones and room-specific cleaning schedules.
