The short version

The PCR-3100 makes its strongest case beside the dustbin

A generous dustbin and a hard floor focus give the PCR-3100 a useful everyday role. We favour it for keeping routine dust from becoming another evening task. Homes expecting it to replace every session with the main vacuum should temper that ambition.

Verdict

7.5/10

Sichler PCR-3100 brings useful help to a familiar chore

A kitchen floor with less dust waiting beneath your slippers is a worthwhile ambition. We consider this robot well placed overall for that ordinary, useful job. Let the dust take up less of your evening.

Our verdict: We recommend it for mostly hard floors and regular upkeep. The DJI Romo A alternative has higher stated battery life, making it worth considering for longer cleaning runs without promising whole-home coverage before recharging.

One caveat Avoid it if your priority is pet fur embedded in carpet: the modest suction specification is what holds us back from recommending it for that job. A spacious bin cannot do the pulling.

Who it's for

Who should give the PCR-3100 a place in the house?

  • Pet households with mostly hard flooring
  • Busy evenings with less routine vacuuming
  • People wanting longer gaps between bin emptying

This model suits households with pets and mostly hard flooring, where dust and loose debris keep returning between proper cleans. If you would rather spend Saturday morning out for a walk than circling the kitchen with a vacuum, its regular upkeep role has appeal. The generous bin also suits people who want longer gaps between emptying.

Less suitable if

Look elsewhere if your main aim is a robot that can take over demanding carpet cleaning. This model makes more sense as help with routine maintenance than as a reason to retire the main vacuum.

Our scores explained

Every model on the site is scored on the same criteria, using the same scale for all: its rank among models with a verified specification. Last place scores 6.5, first place 9.6, with the rest scored proportionally to their rank. Here's how this model's scores were calculated.

Two model counts: the rank and average include models with a product page scored on this criterion; the calculation compares this model with all catalogue models with a verified specification, whether or not they have a product page. A score assigned at publication may remain without a verified specification, so the first count can be higher.

Our full methodology

Detailed analysis

The dog has settled down, the kettle is on, and a scatter of dust across the kitchen floor is still waiting for you. The Sichler PCR-3100 offers a route towards less daily vacuuming, with a generous dustbin, a mop function and voice assistant support. Its strongest case is regular hard floor upkeep, especially when you would rather sit down after work than fetch the vacuum.

With 500 mL, the PCR-3100 robot vacuum cleaner leaves room for daily dust

A robot becomes more appealing when you are not constantly following it to the bin. The PCR-3100 has a 500 mL dustbin, a generous capacity that should allow longer intervals between emptying. For a home with pets, that is a practical attraction: dust and loose fur still need somewhere to go while you get on with your evening.

Consider the hallway after everyone has come in, with small bits of dirt scattered towards the kitchen. Regular vacuuming could keep that accumulation more manageable, while the larger container gives the routine some breathing room. There is less appeal in handing over the vacuuming if you immediately inherit a constant emptying job.

Capacity earns its keep. We would still check the bin regularly rather than wait for it to become packed, especially during a pet's shedding season. A roomy container helps with maintenance; collection depends on the cleaning system too.

The PCR-3100 puts 1600 Pa to work on everyday hard floor dust

What do you actually want collected: dust across kitchen tiles, or fur woven into a thick sitting room carpet? The stated 1600 Pa suction points towards everyday dust on hard floors. That gives this model a clear role in a house where wooden flooring and tiles make up most of the cleaning route.

Its pet-friendly designation needs that context. The modest suction specification makes us cautious about recommending it for carpets full of pet hair. A dog can turn a favourite rug into a remarkably effective fur collection system without contributing anything to its upkeep.

For routine dust beneath the dining chairs, the specification is more encouraging. The robot also has 2 side brushes, giving its cleaning arrangement brushes at the sides as well as suction beneath the body. Their presence alone says little about the finish along skirting boards. Manufacturers measure suction pressure differently, so the figure helps position the machine without promising a clean carpet.

Could 90 min give this robot vacuum enough time for your flat?

The stated 90 min battery life suggests a decent cleaning run before returning to recharge. That gives a regular routine some useful scope while you are occupied elsewhere, rather than leaving another chore squeezed between getting home and making dinner. Coming back from work to less dust underfoot is the attraction.

Keep the setting in mind. The maker's runtime figure comes from the gentlest setting; stronger suction or mopping shortens the run. Your layout and cleaning demands determine how much floor gets covered before recharging, so treat that duration as a guide to planning rather than a whole-home promise.

The stated noise level of 63 dB sits around the average. We would organise cleaning around your household's routine rather than assume it will disappear beneath a television programme. Before a run, follow manufacturers' preparation advice and lift socks, charging cables and small objects from the floor. The laundry basket still has a job.

A mop gives the PCR-3100 robot vacuum cleaner another hard floor chore

A mop function broadens the appeal for kitchen tiles and other suitable hard flooring. After an afternoon snack, vacuuming addresses loose debris while damp floor upkeep serves a different purpose. We like the combination for regular maintenance, provided you keep expectations grounded: a dragged mop dampens the surface rather than scrubbing it like a hand mop.

Wooden flooring needs some thought before moisture enters the picture. Manufacturers advise checking that unfinished, waxed or poorly sealed wood can tolerate damp cleaning. That check belongs before adding mopping to your routine, particularly if your kitchen tiles lead straight into a wooden sitting room floor.

Connectivity is specified as Wi‑Fi 2,4 GHz, which means checking that your router offers the matching Wi-Fi band before ordering. Alexa compatibility and Google Assistant support also give this robot a place in a household that uses voice commands. Those conveniences sit alongside the familiar business of preparing the floor and looking after the cleaning parts.

Our Sichler PCR-3100 review favours routine upkeep over ambitious cleaning

For the everyday job of keeping floor dust in check, this robot is well placed overall in our assessment. Its strongest argument is practical: a generous dustbin, useful runtime and a mop function suit someone trying to reduce the floor work waiting at home. The appeal is steady assistance with a familiar chore.

The DJI Romo A has higher stated battery life at 180 min, a reason to consider it when your priority is a longer cleaning run rather than a guarantee of covering the whole home before recharging. That longer running window is useful when your intended cleaning route stretches beyond the kitchen and hallway. The DJI Romo A is also better rated overall. For a more ambitious cleaning routine, those are concrete reasons to consider the alternative.

Before ordering, check replacement brushes and mop pads, warranty support and the returns policy with the retailer. Those arrangements deserve a place in your decision: you want straightforward access to the parts and help that keep a household appliance useful.

Frequently asked questions

Your questions about living with this robot vacuum cleaner

Does the PCR-3100 suit a home with pets?

It is designated pet-friendly, and its generous dustbin makes routine collection appealing. We would favour it for loose debris on hard floors, while keeping the main vacuum available for more demanding cleaning.

How long can the PCR-3100 clean before recharging?

Stated battery life is 90 min, enough to suggest a decent cleaning run. That figure comes from the gentlest setting; stronger suction or mopping reduces runtime. Your home's layout and cleaning demands determine how far the run gets.

Can I use voice commands with this robot vacuum?

The PCR-3100 supports Alexa and Google Assistant. Its connection is Wi‑Fi 2,4 GHz, so your router needs to offer that Wi-Fi band. Voice commands add convenience, while preparing the floor and maintaining the cleaning parts remain part of the routine.

What should I check before buying and maintaining it?

Check that replacement brushes and mop pads are available, alongside the retailer's warranty support and returns policy. Plan to check the robot's bin and maintain its cleaning parts regularly. Easy access to those essentials matters when you want it working throughout the week.
