8 Best Robot Vacuums Under $100 (2025 Guide)

This 2-in-1 robot vacuum and mop combo delivers a compelling balance of power and convenience, making it a standout for budget-conscious buyers who refuse to compromise on core performance. With 4200Pa of strong suction, it confidently tackles embedded dirt and daily debris across hard floors and low-pile carpets, while its smart obstacle avoidance helps prevent frustrating jams—especially in cluttered living spaces. The inclusion of app and voice control compatibility with Alexa adds a modern touch, letting users automate cleaning routines effortlessly, a feature typically reserved for higher-end models.

In real-world testing, the vacuum maintains consistent coverage using a methodical zig-zag pattern, efficiently navigating open floor plans up to 1,500 sq. ft. before returning to its dock. It transitions smoothly between surfaces, though the mopping function is best suited for light maintenance rather than deep scrubbing—ideal for homes with mostly hard flooring. While the water tank is modest, it provides even dampness without leaks, and the self-charging capability ensures no job is left unfinished. However, it struggles slightly in dark corners where sensors misread shadows as drop-offs, occasionally causing hesitation or detours.

Positioned as the best overall pick under $100, this model outshines basic robots by blending solid suction, smart navigation, and mopping in one package. Compared to the ILIFE V2, it offers far more functionality with app control and stronger cleaning power, though it lacks the ultra-tangle-free design favored by pet owners. For those upgrading from a manual mop or basic sweeper, this robot delivers a smart, all-in-one solution that punches above its price point—offering more features and intelligence than simpler models, without the complexity of premium units.

If raw cleaning power is your top priority, the Pureatic V3 is an absolute beast in the sub-$100 robot vacuum arena. Boasting 5000Pa of continuous suction, it outmuscles nearly every competitor in this range, making quick work of pet hair, cereal crumbs, and embedded dust on both hardwood and low-pile carpets. Its tangle-free suction port and dual-flow channel are engineered with pet owners in mind—no more yanking clumps of fur from bristles. This is a robot that dominates on deep-cleaning tasks, solving the #1 pain point for homes with shedding animals.

During testing, the Pureatic V3 consistently cleared thick layers of pet hair from area rugs and baseboards, a task where lower-suction models often falter. The gyroscope-based smart navigation enables a predictable zig-zag path, ensuring full-room coverage with minimal missed spots. It climbs 0.6-inch thresholds with ease and adjusts water flow during mopping via the app for a customizable clean. However, its 2.4GHz Wi-Fi-only requirement can be a hurdle for users with dual-band routers, and the app occasionally lags during mode switching—minor frustrations that don’t outweigh its cleaning prowess.

When compared to the Lefant M210 Pro, the Pureatic V3 trades slightly quieter operation for superior suction and a larger 650ml dustbin, making it better suited for larger homes or multi-pet households. It’s the go-to choice for users who prioritize maximum debris pickup over whisper-quiet runs, and who want a 3-in-1 vacuum, sweep, and mop without overspending. While it doesn’t have the sleekest app experience, its cleaning performance is unmatched in this price bracket, delivering power usually found in more expensive units.

The AIRROBO robot vacuum shines as a feature-packed smart cleaner that brings high-end convenience to an affordable price. With smart navigation and a 120-minute runtime, it covers large apartments thoroughly, using a zigzag cleaning pattern to maximize efficiency—no random bouncing here. Its 2800Pa suction may not top the charts, but it’s more than sufficient for daily maintenance on hard floors and low-pile carpets, especially in homes with pet hair. What sets it apart is the intuitive app interface, which lets users schedule cleanings, switch modes, and monitor progress remotely—perfect for busy households.

In practice, the AIRROBO delivers consistent, reliable performance across tile, laminate, and area rugs. It detects edges and avoids stairs with precision thanks to advanced anti-drop and anti-collision sensors, and its ultra-thin 3-inch profile slips under sofas and beds with ease. The 3-stage cleaning system captures fine dust and larger debris alike, though it’s not as aggressive on thick pet hair as tangle-free models. On carpet, suction doesn’t auto-boost, so users must manually switch to Turbo mode for deeper cleans—a small oversight in an otherwise smart design.

Compared to the Vexilar, the AIRROBO offers better app functionality and longer runtime, though it’s slightly louder in high-power mode. It’s ideal for tech-savvy users who want a seamless smart home integration without paying premium prices. While it doesn’t lead in suction or mopping, it strikes an excellent balance—delivering smart navigation, strong connectivity, and dependable cleaning in one well-rounded package. For those who value automation and control, this is the most intelligent pick under $100.

For buyers seeking no-frills reliability at the lowest price, the ILIFE V2 is the undisputed budget king—a stripped-down workhorse that gets the job done without app clutter or voice gimmicks. With a tangle-free suction port, it excels at picking up pet hair without clogs, a major win for fur-parents tired of maintenance. Its 2.99-inch slim body glides under furniture effortlessly, and the 120-minute runtime covers up to 1,200 sq. ft., returning to its dock automatically when done. This is a robot built for simplicity, durability, and daily upkeep.

In real-world use, the ILIFE V2 performs admirably on hard floors and low-pile rugs, using a random navigation pattern that, while not as efficient as smart mapping, still covers most rooms over time. It handles baseboards and corners well thanks to dual edge brushes, and its anti-bump and anti-fall sensors prevent accidents on stairs. However, without app control, scheduling must be done manually via remote—double-pressing buttons isn’t as intuitive as tapping a screen. And while it’s quiet enough for background cleaning, the lack of suction adjustment limits versatility.

Stacked against the Lefant M210, the ILIFE V2 trades smart features for rock-bottom pricing and mechanical reliability. It’s perfect for renters, seniors, or anyone who wants a set-it-and-forget-it cleaner without smartphone dependency. While it can’t match the intelligence or power of pricier bots, it delivers solid core performance where it counts—suction, runtime, and pet-hair pickup. For those who want the most value for the least money, this is the smartest basic robot vacuum under $100.

The Lefant M210 redefines what’s possible in the budget robot vacuum space by offering true smart home integration without breaking the bank. Its brushless suction port is a game-changer—designed specifically to pull in pet hair without tangling, eliminating one of the most common pain points for owners. With up to 120 minutes of runtime on a single charge and FreeMove 3.0 anti-collision tech, it navigates complex layouts with fewer snags, making it ideal for homes with furniture clutter.

In testing, the M210 proved highly responsive to app commands, with smooth mode switching and real-time cleaning tracking via the Lefant app. The six cleaning modes, including scheduled and edge cleaning, offer impressive flexibility for a sub-$90 robot. It operates quietly at ≤55dB, making it suitable for daytime or nighttime runs without disturbing pets or babies. However, users must ensure they download the correct app—Lefant, not Lefant Life—or risk connectivity issues, a quirk that could frustrate less tech-savvy buyers.

Against the AIRROBO, the M210 offers similar smart features but better pet-hair handling and quieter operation. It’s the best choice for pet owners who want voice and app control without sacrificing reliability. While it doesn’t have the strongest suction, its balanced mix of intelligence, tangle-free design, and ease of use makes it a top contender. For those seeking a smart, pet-friendly robot that integrates seamlessly into daily life, the M210 delivers exceptional value with modern convenience.

The Lefant M210 Pro is the evolved successor to the M210, fine-tuned for homes dominated by pets and daily messes. With 2200Pa suction and self-adjusting rubber brushes, it lifts pet hair from medium-pile carpets and hardwood with zero tangles—a rare feat at this price. Its ultra-slim 2.99-inch body slips under furniture like a shadow, while Freemove 3.0 sensors prevent collisions and drop-offs with impressive accuracy. This is a robot built for real homes with real fur, crumbs, and clutter.

During extended use, the M210 Pro maintained consistent performance across varied floor types, automatically boosting suction on carpets for deeper cleaning—a feature missing in many budget models. The Lefant app offers full control over modes, schedules, and suction levels, and voice commands via Alexa work flawlessly. It runs up to 120 minutes and returns to charge without user input. The only caveat? Zigzag mode should be avoided on carpets, where it can get stuck—stick to random mode for best results.

Compared to the Pureatic V3, the M210 Pro trades raw suction for smarter navigation and quieter operation, making it better for households that clean frequently rather than deeply. It’s the best choice for pet owners who want quiet, daily maintenance with zero hair hassles. While not the most powerful, its balanced performance, pet-optimized design, and smart features make it the most well-rounded pick for furry homes—offering refined cleaning intelligence at a mid-range price.

The betboyles robot vacuum and mop combo stands out as the most capable mopping robot under $100, combining solid suction with a 250ml water tank and washable mop cloth for homes that prioritize floor shine as much as suction. Its 400ml dustbin is larger than average, reducing emptying frequency, and the 2200Pa suction handles daily debris and pet hair with ease. With 6 cleaning modes, including a dedicated Mop mode, it offers flexibility unmatched by basic models—ideal for homes with mostly hard flooring.

In real-world testing, the mopping function delivered even, streak-free results on tile and hardwood, outperforming competitors with smaller tanks. The smart app allows precise control over water flow and cleaning patterns, and voice commands via Alexa work reliably. It navigates with a mix of sensors and obstacle avoidance, though it occasionally misses tight corners. The 120+ minute runtime covers up to 1,600 sq. ft., but performance dips on thick carpets where mopping isn’t recommended.

Versus the base Lefant M210, the betboyles model adds true mopping functionality and a larger bin, making it better for homes that mop regularly. It’s the go-to for users who hate switching between vacuum and mop. While suction isn’t class-leading, its dual cleaning capability and smart scheduling make it the most practical 3-in-1 option for hard-surface homes. If you want one robot to handle dust, debris, and floor shine, this delivers the best mopping performance under $100.

The Vexilar robot vacuum earns its title as the quietest performer under $100, operating at just 60dB in quiet mode—so silent it can run during naps or late-night cleaning without disturbance. Its brushless motor delivers 2000Pa suction with less noise and longer lifespan, making it perfect for apartments, nurseries, or noise-sensitive environments. With a 2.89-inch ultra-slim profile, it accesses tight spaces other bots miss, and the 360-degree universal wheel enhances maneuverability around furniture legs and corners.

In testing, the Vexilar handled hard floors and low-pile carpets effectively, using carpet boost technology to increase suction when needed. The Vactidy app allows full scheduling and mode control, and voice commands via Alexa or Google Assistant work reliably. However, the 100-minute runtime falls short for larger homes, and navigation relies on random patterns rather than smart mapping, leading to occasional inefficiencies. It also struggles on darker rugs where sensors misread elevation.

Compared to the AIRROBO, the Vexilar offers quieter operation and a slimmer profile but sacrifices battery life and advanced navigation. It’s best for small to medium spaces where noise level is a top concern. For light daily cleaning in studios, bedrooms, or offices, it provides stealthy, unobtrusive performance—making it the top pick for quiet, compact cleaning without app bloat or loud motors.
