Still deciding? Follow the whole category.

Robot vacuums, vacuum-and-mop combos and dedicated robot mops. Any brand, with optional budget and discount filters.

THE SHORT ANSWER

Which robot vacuum should you buy?

Our overall vacuum-and-mop pick is the Roborock Saros 10R. For vacuuming only, compare the budget Roomba 105 Vac with our overall pick, the Shark PowerDetect AV2820S. If you already vacuum and only need a robot mop, see the Braava jet m6 and its limitations.

Need an affordable combination? Compare the Q7 M5+ budget self-emptying combo and MOVA P10 Pro Ultra value pick. Check each model’s historical low before deciding whether its current offer is attractive.

Roborock

Roborock Saros 10R review

Our overall pick for its combination of navigation, hard-floor cleaning and automated dock care. It is strongest in mainly hard-floor homes; carpet pet hair and the current asking price are the reasons to pause.

24/24Obstacle-avoidance testVacuum Wars ↗

What the reviews tell us

RTINGS found excellent hard-floor pickup and effective mopping, but struggled to remove embedded carpet fur. Vacuum Wars recorded 91.5% pickup in its flattened-hair test. Those results describe different jobs, so we would prioritize this model for hard-floor homes.

+ Reasons to shortlist

  • Low profile for reaching beneath furniture
  • Strong hard-floor and stain-cleaning results

− Trade-offs to know

  • Embedded carpet fur is a weakness
  • A premium design with a premium asking price
THE DEALAGRAM PRICE TAKE

The checked item price is $700.00 above this listing’s 180-day low of $899.99. The time-weighted new-price average was $1,163.13. Shipping is separate from the historical series.

iRobot

iRobot Roomba 105 Vac review

Our budget vacuum-only pick makes room-by-room cleaning affordable. This exact 105 Vac listing includes a charging dock: it does not mop, and you empty its dustbin yourself.

LiDARMapping with room selectioniRobot specifications ↗

What the reviews tell us

RTINGS recommends the 105 for low-cost routine cleaning. Vacuum Wars found good carpet-debris pickup when testing the AutoEmpty version of the 105 Vac, but pet hair, long-hair tangles and battery efficiency were weaknesses. Its mapped routes are more controllable than random-navigation robots; clear cables and small clutter before it runs.

+ Reasons to shortlist

  • LiDAR maps, room selection and no-go zones
  • A lower entry price without mop upkeep

− Trade-offs to know

  • Manual dustbin emptying on this listing
  • Weak flattened-hair pickup; not our pet-heavy-home pick
THE DEALAGRAM PRICE TAKE

The checked item price is $25.50 above this listing’s 180-day low of $134.49. The time-weighted new-price average was $153.34. Shipping is separate from the historical series.

Before you buy

Buy the 105 Vac, not the 105 Combo. This ASIN has the charging dock, not the AutoEmpty dock. The linked Vacuum Wars test and iRobot specifications cover the AutoEmpty sibling; their dock capacity and dock convenience do not apply to this package. The robot cleaning findings are useful context, not a separate test of this bundle.

Shark

Shark PowerDetect AV2820S review

Our overall vacuum-only choice combines automatic dust disposal with capable carpet cleaning. The AV2820S has a bagless HEPA base and no water tanks or mop pads to maintain. Its current price deserves a close look at the history before you buy.

30 days*Advertised bagless dock capacityShark · exact AV2820S ↗

What the reviews tell us

Vacuum Wars found strong carpet deep-cleaning and debris pickup on the larger-dock AV2820AE sibling. Battery efficiency, app flexibility and small-object avoidance were compromises, and long hair still wrapped around the brush. Just A Dad identifies the AV2820S as the same robot with a smaller base. We use those cleaning findings with that model distinction made explicit.

+ Reasons to shortlist

  • Self-emptying without disposable dust bags
  • Good carpet-debris results on the tested sibling

− Trade-offs to know

  • Not dependable around every small obstacle
  • Less flexible app; brush still needs hair removal
THE DEALAGRAM PRICE TAKE

The checked item price is $220.00 above this listing’s 180-day low of $329.99. The time-weighted new-price average was $510.04. Shipping is separate from the historical series.

Before you buy

This is the AV2820S, with the smaller up-to-30-day base; the AV2820AE reviewed by Vacuum Wars has a larger up-to-60-day base. Emptying frequency depends on your home and debris. Neither is a mop combo. There is no claim here that DEALAGRAM physically tested either variant.

Roborock

Roborock Q7 M5+ review

Our budget self-emptying combo keeps LiDAR mapping and automatic dust disposal at a lower cost than the fully automated mop systems in this shortlist. Mopping uses a basic removable pad that needs manual care.

Basic padOccasional hard-floor wipingVacuum Wars ↗

What the reviews tell us

RTINGS found strong hard-floor and carpet pet-hair cleaning on the Q7 M5 and confirms the Plus adds the dust dock. Vacuum Wars praised navigation but recorded more modest flattened-hair results. Its mop is a stationary pad that needs manual care; it cannot lift itself over rugs.

+ Reasons to shortlist

  • LiDAR mapping and self-emptying dock
  • Basic detachable mop for hard floors

− Trade-offs to know

  • No mop lifting or washing at the dock
  • Clear small clutter before cleaning
THE DEALAGRAM PRICE TAKE

The checked item price is $145.00 above this listing’s 180-day low of $214.99. The time-weighted new-price average was $276.45. Shipping is separate from the historical series.

Before you buy

The linked ASIN is the Q7 M5+ with its self-emptying dock. RTINGS tested the Q7 M5 robot and identifies the dock as the Plus model's difference. This dock empties dust; it does not wash mops or refill water. Its price can move quickly: compare the current quote with the history rather than assuming this budget pick is always on sale.

MOVA

MOVA P10 Pro Ultra review

Our vacuum-and-mop value choice for mostly hard-floor homes. It combines everyday pickup with a dock that washes and dries its pads, making it a practical step up from a basic wipe-only mop.

OriginalP10 Pro Ultra generationModel-specific review ↗

What the reviews tell us

RTINGS found good hard-floor pickup and capable obstacle avoidance. Its carpet results were weaker: the side brush stays inactive on carpet, and embedded pet hair is difficult to lift. We would shortlist it for mostly hard floors and dock convenience.

+ Reasons to shortlist

  • Dock handles emptying and mop care
  • Good hard-floor edge cleaning

− Trade-offs to know

  • Misses material along carpet edges
  • Poor embedded pet-hair pickup
THE DEALAGRAM PRICE TAKE

The checked item price is $79.00 above this listing’s 180-day low of $320.00. The time-weighted new-price average was $403.76. Shipping is separate from the historical series.

iRobot Braava jet m6 review

Already happy with your vacuum? This dedicated robot adds mapped wet mopping without another vacuum system. It can dry-sweep with a different pad, but it has no vacuum suction.

Mop onlyNo vacuum suctioniRobot specifications ↗

What the reviews tell us

Tom’s Guide found effective kitchen cleaning and accurate targeted zones, with a light water trail that dried quickly. Its 70-square-foot mopping test took about 30 minutes. Good Housekeeping still includes the m6 for shoppers who want a separate mop.

+ Reasons to shortlist

  • Room mapping and targeted cleaning zones
  • A dedicated mop to complement an existing vacuum

− Trade-offs to know

  • Older design; refill water and service pads by hand
  • No vacuuming or automatic pad-washing dock
THE DEALAGRAM PRICE TAKE

The checked item price is $30.99 above this listing’s 180-day low of $169.00. The time-weighted new-price average was $187.95. Shipping is separate from the historical series.

Before you buy

The linked product is the white m6 / M6110. New offers were available from third-party marketplace sellers, with seller fulfillment. Check the specific seller, warranty and return terms. This is a dedicated-mop option for accessible hard floors, not our recommendation for an all-in-one cleaner.

eufy Omni E25 review

Our pick here for households interested in a roller mop. It continually rinses the roller and separates dirty water while cleaning, rather than relying only on dock washes.

88%Carpet deep-clean pickupVacuum Wars ↗

What the reviews tell us

Vacuum Wars measured 88% embedded-grit pickup and 93% flattened pet-hair pickup. Its wet-spill results were encouraging, although it left more residual moisture than the test average and the roller does not extend out to the wall.

+ Reasons to shortlist

  • Roller refreshed with clean water
  • Promising carpet-cleaning test results

− Trade-offs to know

  • Roller does not extend to wall edges
  • Check the early water-tank caveat below
THE DEALAGRAM PRICE TAKE

The checked offer matches this listing’s tracked 180-day low. The time-weighted new-price average was $661.33. Shipping is separate from the historical series.

Before you buy

Vacuum Wars reports leaks in early dirty-water tanks and says eufy supplied corrected tanks. The reviewer did not experience the fault. This is a reported correction, not a long-term reliability guarantee. Our history follows the current linked ASIN only.

Dreame X50 Ultra review

The specialist for awkward room transitions. Retractable navigation hardware and powered climbing assistance make it worth investigating when a home's layout limits other robots.

97.5%Flattened pet-hair pickupVacuum Wars ↗

What the reviews tell us

Vacuum Wars measured 97.5% flattened pet-hair pickup with no wrapping in its seven-inch hair test. RTINGS was less impressed by fine-dust pickup on hard floors and stain removal. We would choose it for access and layout flexibility before mopping alone.

+ Reasons to shortlist

  • Powered assistance for suitable thresholds
  • Retractable LiDAR for lower clearances

− Trade-offs to know

  • Fine dust may need another pass
  • Stain-cleaning results were mixed

The checked item price is $150.00 above this listing’s 180-day low of $849.99. The time-weighted new-price average was $924.86. Shipping is separate from the historical series.

Before you buy

Dreame's advertised 60 mm climbing figure applies to suitable multistep obstacles. It is not a promise to clear a single vertical 60 mm ledge. Measure your thresholds and check the manufacturer's conditions.

BEFORE YOU BUY

The questions
worth asking.

Choose around your floors, maintenance tolerance and budget. A spec sheet is only part of the story.

Which one should I choose for a home with pets?

Separate loose hair from fur embedded in carpet. Vacuum Wars' flattened-hair tests favored the Dreame over the Saros, while RTINGS found embedded-hair limitations on both. Treat the tests as different evidence, and keep your floor type in mind. Read the comparison ↗

What is the difference between mopping only and a mop combo?

The Braava jet m6 has no vacuum suction: it wet-mops or dry-sweeps with the appropriate pad. Choose it to complement an existing vacuum. The E25 is a vacuum-and-mop combo with a rinsed roller; the MOVA and Saros use spinning pads. A dedicated mop is not automatically a better mop—it simply fills a different need.

Should I buy now or set a notification?

Compare the latest price with the same ASIN's history. A price near its recorded low may already be attractive. A large gap can justify setting a lower target if you can wait. Previous discounts do not guarantee another sale, and seller quality, shipping and warranty still matter.

What does a self-cleaning dock actually save me?

The Q7 M5+ empties dust, but its mop pad needs manual care. The Saros, MOVA, E25 and X50 also wash and dry their mops. The Braava m6 is different: it only mops or dry-sweeps, and its dock only charges. You still need to refill clean water, empty dirty water, replace consumables and clean components. Check the manufacturer's maintenance instructions and whether the dock fits your available space.

Why don't you give every robot a single score?

A numerical average would hide differences in test conditions and household needs. We credit each publisher's measurements and explain the trade-offs. Our awards describe the role each product fills in this eight-model shortlist.

Are these today's newest robot vacuums?

No. This guide focuses on eight established models with published testing and usable price history. Newer models exist. The goal is to evaluate the fit and price of these exact products; we do not claim a complete survey of the market.

HOW THIS GUIDE WAS MADE

Research you can follow.
Numbers you can check.

This is an AI-assisted research synthesis of independent published tests, manufacturer specifications and Keepa observations. DEALAGRAM has not physically tested these robots. We selected eight established models for distinct needs: overall performance, budget and overall vacuum-only picks, a budget self-emptying combo, affordable automated vacuuming and mopping, a dedicated mop, roller mopping and raised thresholds. We retained material drawbacks, including conflicting test results.

Price and review sections have different jobs: published tests inform product suitability; actual historical observations inform the price discussion. The choices are editorial judgments within this shortlist, not endorsements from the source publishers.

Price updates: Prices, new-offer availability and history refresh about once a day. Each item shows its own last successful check in your local time. Delayed checks are marked overdue; prices can change between checks. Editorial reviews are updated separately.

Amazon availability

We checked the exact Amazon US listing for a fresh new-condition offer that was shippable, not a preorder or backorder. At selection, every listing had a new-offer price recorded for at least 95% of the preceding 90 days. Availability may subsequently change; unavailable products remain visible with their history and a clear status. Historical price coverage is a useful availability signal, not proof of stock at every moment or delivery to every address.

Some listings may be offered through Other sellers or fulfilled by marketplace sellers; those distinctions appear beside the buying links. The selected seller can change at each refresh. Check the current seller, delivery, warranty and returns on Amazon.

Price methodology

Source: Keepa Product API, Amazon US, NEW history (new marketplace offers). Prices exclude shipping, tax, coupons, membership-only offers and used products. One ASIN per model; histories are not stitched across replacement listings or variants.

Time-weighted averages use available-price intervals through the product's last history update. Missing intervals are omitted. The low is the minimum observed price within the selected range; it is not an all-time or all-retailer claim. The suggested target rounds the 180-day item-price low up to the nearest $25. Individual notifications compare your target with the checked new offer plus listed shipping, before tax or coupons. They send once per confirmed target. Category notifications find new matching robot-cleaner deals beyond this shortlist, at least 10% below their 90-day new-price average; the first scan establishes a baseline. Timing depends on the scanner and available data.
